Recreational and problem gambling have been linked with adverse health and functioning outcomes among adolescents. Youth may gamble and engage in other risk-taking behaviors in casinos. There are limited data available regarding casino gambling in high-school students, and factors linked to adolescent gambling in casinos have yet to be systematically investigated. To address this gap, we analyzed cross-sectional data from 2010 Connecticut high-school students with chi-square tests and logistic regression models to examine casino gambling in relation to at-risk/problem gambling (ARPG) with respect to sociodemographic characteristics, gambling perceptions & attitudes, health/functioning measures and gambling behaviors. Approximately 11 % of adolescents acknowledged gambling in casinos. ARPG was more frequent and gambling perceptions were more permissive among adolescents endorsing casino gambling. Stronger relationships between ARPG and heavy alcohol and drug use and weaker relationships between ARPG and engagement in extracurricular activities, gambling with friends, gambling with strangers and gambling for financial reasons were observed among adolescents endorsing casino gambling. In conclusion, gambling in casinos was endorsed by a sizable minority of adolescents who gamble, and prevention efforts should consider targeting permissive attitudes towards gambling, adolescent drinking and participation in extracurricular activities when addressing underage casino gambling.

Cannabis use and related disorders are common in adults and frequently co-occur with subsyndromal and pathological gambling. However, understanding how cannabis use may moderate relationships between problem-gambling severity and psychiatric disorders remains poorly understood. Data from the National Epidemiological Survey on Alcohol and Related Conditions (N = 43,093 adults) were examined to investigate how cannabis use moderated associations between problem-gambling severity (with gambling groups based on the 10 Diagnostic and Statistical Manual [DSM-IV] inclusionary criteria for pathological gambling) and Axis I and Axis II psychiatric disorders. Problem-gambling severity groups included low frequency/nongambling, low-risk gambling, at-risk gambling, and problem/pathological gambling (PPG). Among both the group with lifetime cannabis use and that which never used cannabis, greater problem-gambling severity was associated with more psychopathology across mood, anxiety, substance-use and Axis II disorders. Significant Cannabis Use × Problem-Gambling Severity Group interactions were observed between PPG and major depression (OR = 0.35, 95% CI = [0.14-0.85]), cluster A personality disorders (OR = 0.37, 95% CI = [0.16-0.86])-especially paranoid personality disorder (OR = 0.34, 95% CI = [0.14-0.81])-and cluster B personality disorders (OR = 0.36, 95% CI = [0.18-0.75])-especially antisocial personality disorder (OR = 0.25, 95% CI = [0.11-0.60]). In all cases, associations between problem-gambling severity and psychopathologies were weaker among the lifetime-cannabis-using group as compared to the never-using group. Cannabis use moderates the relationships between problem-gambling severity and psychiatric disorders, with cannabis use appearing to account for some of the variance in the associations between greater problem-gambling severity and specific forms of psychopathology.

Various theoretical perspectives have informed intervention and program development in postpartum health, including the transtheoretical model, the health belief model, and cognitive and social processes. Mobile technology has been used in recent years to address and promote postpartum health. Mobile technologies utilizing theoretically grounded interventions can be harnessed to improve postpartum behavioral health by decreasing two major barriers to treatment in this population: avoidance of pharmacotherapy and convenient treatment delivery. Specifically, mobile technologies in the postpartum period can tailor messages to user characteristics (e.g. age, number of children, history of depression); link the user with others for increased social support; provide convenient, cost-effective, evidence-based treatment to large populations regardless of location; and provide the ability to send time-sensitive communications to devices. Current interventions for postpartum women include a mobile application for depression that promotes social connectedness and text messaging to promote smoking cessation in perinatal women. Mobile technologies represent a rich medium by which to deliver and facilitate personalized interventions for a variety of health behaviors in postpartum women.

Research has demonstrated a strong relationship between drinking motives and alcohol use among young adult populations. Further, there is substantial evidence of the association between psychosocial stressors and greater alcohol consumption. In the present study, we examined whether acculturative stress would moderate the relationship between major drinking motives and alcohol use behaviors and alcohol-related problems, and whether this relationship differs by racial/ethnic group.Six hundred diverse undergraduate students (mean age=21.50, SD=2.46; 82.8% female; 40.2% White/Caucasian) completed a series of measures, including demographic information, alcohol use/alcohol problems, and acculturative stress.Findings showed varying patterns in the moderating effect of acculturative stress on the relationship between drinking motives and alcohol consumption and alcohol-related problems, particularly for self-identified Hispanic, Black, and Asian students. Stronger drinking motives were associated with greater alcohol consumption and alcohol-related problems, and this relationship was stronger among Asian and Hispanic students who reported higher levels of acculturative stress. For Black students, greater acculturative stress was observed to weaken the relationship between coping, enhancement, and conformity motives and alcohol drinking frequency.Results are discussed in terms of incorporating acculturative stress in the development of tailored alcohol use interventions for vulnerable young adults, such as certain ethnic minority and immigrant groups. Clinical implications include screening for acculturative stress in primary care and counseling centers and early intervention programs to identify young adults who may be at-risk for or currently experiencing alcohol problems.

Introduction The proliferation of electronic devices, such as vape-pens, has provided alternative means for cannabis use. Research has found cannabis-vaping (i.e., vape-pen use) is associated with lower perceived risks and higher cannabis use. Knowledge of these products may increase likelihood of subsequent use. As policies for cannabis shift, beliefs that peers and family approve of this substance use (injunctive norms) increase and there has been an increase in vape-pen use among young adults (18–35 year olds); however, correlates thereof remain unknown. Young adults often engage in cross-substance use with cannabis and alcohol, making alcohol a potential correlate of cannabis vape-pen use and knowledge. Therefore, we examined alcohol use and other potential correlates of vape-pen use and knowledge among a sample of university students. Methods This secondary data analysis utilized surveys at multiple colleges in the U.S. (N = 270). Alcohol use, social anxiety, cannabis expectancies, injunctive and descriptive norms and facets of impulsivity were examined as correlates of vape-pen use and knowledge using bivariate correlations and logistic regressions. Results Alcohol use was correlated with cannabis vape-pen use and knowledge. Frequency of cannabis use, peer injunctive norms, and positive expectancies were associated with increased likelihood of vape-pen use. Lack of premeditation, a facet of impulsivity, was associated with cannabis vape-pen knowledge. Conclusions Given the unknown nature and consequences of cannabis vape-pens, the present findings offer valuable information on correlates of this behavior. Further, correlates of knowledge of vape-pens may point to areas for education and clinical intervention to prevent heavy cannabis vape-pen use., Highlights • More cannabis use was related to higher odds of cannabis vape-pen use. • Vape-pen use for cannabis was related to alcohol use. • Each drink per drinking day related to 12 times greater likelihood of cannabis vape-pen use. • Higher cannabis injunctive norms and expectancies predicted cannabis vape-pen use. • Knowledge of cannabis vape-pens was associated with lack of premeditation.

Cannabis is the most commonly used illicit substance worldwide. In recent decades, highly concentrated products have flooded the market, and prevalence rates have increased. Gender differences exist in cannabis use, as men have higher prevalence of both cannabis use and cannabis use disorder (CUD), while women progress more rapidly from first use to CUD. This paper reviews findings from preclinical and human studies examining the sex-specific neurobiological underpinnings of cannabis use and CUD and associations with psychiatric symptoms. Sex differences exist in the endocannabinoid system, in cannabis exposure effects on brain structure and function, and in the co-occurrence of cannabis use with symptoms of anxiety, depression, and schizophrenia. In female cannabis users, anxiety symptoms correlate with larger amygdala volume, and social anxiety disorder symptoms correlate with CUD symptoms. Female cannabis users are reported to be especially vulnerable to earlier onset of schizophrenia, and mixed trends emerge in the correlation of depressive symptoms with cannabis exposure in females and males. As the prevalence of cannabis use may continue to increase given the shifting policy landscape regarding marijuana laws, understanding the neurobiological mechanisms of cannabis exposure in females and males is key. Examining these mechanisms may help inform future research on sex-specific pharmacological and behavioral interventions for women and men with high-risk cannabis use, comorbid psychiatric disease, and CUD.

Background and Objectives As a measure of nicotine dependence among adolescent smokers, the modified Fagerstrom Tolerance Questionnaire (mFTQ; seven items), has been successfully used in the United States (USA). Nonetheless, the validity and reliability of mFTQ at the international level is still needed. The current study is the first to test the validity and reliability of mFTQ in four countries: Thailand, Spain, the USA, and Russia. Methods In a cross-sectional survey, mFTQ, risk factors of nicotine dependence, and sociodemographic characteristics were assessed. Risk factors included age of first cigarette, frequency of alcohol use, frequency of marijuana use, and number of cigarettes smoked yesterday. Salivary cotinine was also obtained in Thailand and Spain. Results For all four countries, mFTQ exhibited a single factor structure, as supported by previous work in the USA. For all studied countries except Thailand, mFTQ presented acceptable internal reliability. Overall, risk factors of nicotine dependence have predicted mFTQ scores across countries. Frequency of alcohol use in the USA and frequency of marijuana use in Thailand and Spain were not associated with mFTQ scores. Discussion and Conclusions mFTQ is a single-factor measure of nicotine dependence that shows acceptable internal consistency and validity across countries. Further work can advance the scale and tailor it to different cultures. Scientific Significance mFTQ can be a clinically practical international measure of nicotine dependence. This study provides initial support for the utility of the mFTQ among Thai, Spanish, American, and Russian adolescents. Further research is needed to test and advance mFTQ across cultures.

Cannabis use among college students is associated with negative consequences, including those that can negatively affect academic functioning. Perceived descriptive and injunctive norms are among the strongest predictors of college cannabis use and related problems, and perceived norms differentially relate to cannabis outcomes depending on the reference group (e.g., close friends, family members). However, no known studies have examined the effect of race on these relationships. Yet, given that African American students are more strongly affected by parental influence than Caucasian students and that they endorse more social motives for cannabis use, African American students may be affected by perceived norms regarding parents and friends differentially from Caucasian students. The current study tested the moderational role of race on the relationship between perceived norms and cannabis use and related problems. Cannabis-using undergraduates (N = 103; 78.6% female) completed an online survey. Race moderated the relationship between injunctive norms regarding parents and cannabis-related problem severity such that among African American students (but not Caucasian students), endorsement of more permissive perceived parental injunctive norms was related to greater cannabis-related problem severity (but not cannabis use frequency). Interactions were not significant between race and descriptive norms or between race and peer injunctive norms. African American students who perceive that their parents are more accepting of cannabis use may be especially at risk for cannabis-related problems. Results underscore the importance of considering cultural factors in identification of vulnerability factors related to cannabis problems.

Drawing on constructs from the trauma literature, the current study evaluated perceptions of safety and controllability of events as potential markers of risk for marijuana use. In addition, we characterized these perceptions in relation to individual level substance abuse risk factors (marijuana expectancies, impulsivity, depression, and anxiety), gender, and race. Data were collected via web survey from college students at two northeastern universities (n=228, 82.0% female). Controllability of events (CE) was rated significantly higher by Blacks than Whites. Safety/vulnerability (SV) and CE were associated with impulsivity, depression, and anxiety. CE was also associated with marijuana expectancies. Logistic regression analyses revealed a modest but significant association between SV and lifetime use even after adjusting for race, gender, age, and individual level substance abuse risk factors (odds ratio=1.10, 95% confidence intervals:1.02–1.18). No association between SV and past 3 month frequency of use or between CE and either marijuana outcome was found. Findings support a link between perceptions of safety and ever using marijuana. They further demonstrate overlap of both perceived safety and controllability of events with substance use related risk factors, and suggest that they differ by race. Additional studies that assess substance use more broadly and query trauma history, using larger, more diverse samples, are needed to more fully grasp the relevance of these constructs to substance use, including their potential as targets for substance abuse prevention efforts.

In crystals, microscopic energy flow is governed by electronic and vibrational excitations. In nanoscale materials, however, translations and rotations of entire nanoparticles represent additional fundamental excitations. The observation of such motions is elusive as most ultrafast techniques are insensitive to motions of the phonons’ frame of reference. Here, we study heterostructures of size-selected Au nanoclusters with partial (111) orientation on few-layer graphite with femtosecond electron diffraction. We demonstrate that ultrafast, constrained rotations of nanoclusters, so-called librations, in photo-induced non-equilibrium conditions can be observed separately from vibrational structural dynamics. Molecular dynamics and electron diffraction simulations provide quantitative understanding on librations-induced deviations from the conventional temperature dependence of diffraction patterns. We find that nanocluster librations with a period of ∼20 picoseconds are triggered quasi-impulsively by graphene flexural motions. These ultrafast structural dynamics modulate the Au/C interface and hence are expected to play a key role in energy- and mass-transport at the nanoscale., Nanoscale Horizons, 4 (5), ISSN:2055-6756, ISSN:2055-6764

Cannabis users, especially socially anxious cannabis users, are influenced by perceptions of other's use. The present study tested whether social anxiety interacted with perceptions about peer and parent beliefs to predict cannabis-related problems.Participants were 148 (36.5% female, 60.1% non-Hispanic Caucasian) current cannabis users aged 18-36 (M = 21.01, SD = 3.09) who completed measures of perceived descriptive and injunctive norms, social anxiety, and cannabis use behaviors. Hierarchical multiple regressions were employed to investigate the predictive value of the social anxiety X parent injunctive norms X peer norms interaction terms on cannabis use behaviors.Higher social anxiety was associated with more cannabis problems. A three-way interaction emerged between social anxiety, parent injunctive norms, and peer descriptive norms, with respect to cannabis problems. Social anxiety was positively related to more cannabis problems when parent injunctive norms were high (i.e., perceived approval) and peer descriptive norms were low. Results further showed that social anxiety was positively related to more cannabis problems regardless of parent injunctive norms.The present work suggests that it may be important to account for parent influences when addressing normative perceptions among young adult cannabis users. Additional research is needed to determine whether interventions incorporating feedback regarding parent norms impacts cannabis use frequency and problems.

BACKGROUND: Injunctive norms have been found to be important predictors of behaviors in many disciplines with the exception of alcohol research. This exception is likely due to a misconceptualization of injunctive norms for alcohol consumption. To address this, we outline and test a new conceptualization of injunctive norms and personal approval for alcohol consumption. Traditionally, injunctive norms have been assessed using Likert scale ratings of approval perceptions, whereas descriptive norms and individual behaviors are typically measured with behavioral estimates (i.e., number of drinks consumed per week, frequency of drinking). This makes comparisons between these constructs difficult because they are not similar conceptualizations of drinking behaviors. The present research evaluated a new representation of injunctive norms with anchors comparable to descriptive norms measures. METHODS: A study and a replication were conducted including 2,559 and 1,189 undergraduate students from 3 different universities. Participants reported on their alcohol-related consumption behaviors, personal approval of drinking, and descriptive and injunctive norms. Personal approval and injunctive norms were measured using both traditional measures and a new drink-based measure. RESULTS: Results from both studies indicated that drink-based injunctive norms were uniquely and positively associated with drinking, whereas traditionally assessed injunctive norms were negatively associated with drinking. Analyses also revealed significant unique associations between drink-based injunctive norms and personal approval when controlling for descriptive norms. CONCLUSIONS: These findings provide support for a modified conceptualization of personal approval and injunctive norms related to alcohol consumption and, importantly, offer an explanation and practical solution for the small and inconsistent findings related to injunctive norms and drinking in past studies.Copyright © 2016 by the Research Society on Alcoholism.

This study examined the impact of coping motives for cannabis and alcohol use on the relation between social anxiety/depressive symptoms and severity of substance use for alcohol, tobacco, and cannabis among treatment-seeking smokers who also use cannabis and alcohol.The sample included 197 daily cigarette smokers (MAge 34.81 years, SD = 13.43) who reported using cannabis and alcohol.Hierarchical multiple regression analyses were conducted wherein separate models were constructed for each dependent variable. Among individuals with higher social anxiety, alcohol coping motives were associated with heavier drinking, and this was more pronounced among those low in depressive symptoms. Similarly, those at greater risk for nicotine dependence were anxious individuals with lower depressive symptoms who endorse coping-oriented motives for using cannabis. Further, among those with higher social anxiety, cannabis coping motives were associated with marginally greater drinking, particularly for those high in depressive symptoms.The present findings support the perspective that among multisubstance users, the interplay between social anxiety, depressive symptoms, and coping-oriented motives for using one substance (e.g., cannabis or alcohol) may pose difficulties in refraining from other substances (e.g., tobacco). This observation highlights the importance of tailoring multisubstance treatments to specific needs of multiusers for whom single-substance interventions may be less effective. Findings also support previous work exploring the benefits of concurrently treating co-occurring substance use and lend credence to the perspective that motivation to use substances for coping reasons is of central theoretical and clinical relevance.

The present work examined the influence of drinking motives on hookah use frequency among individuals reporting both alcohol and hookah use (multi-substance users). Despite growing documentation of cross-substance effects between motives and substance use, limited research has examined these relationships specifically with respect to hookah use. Participants were 134 (75.37 % female) hookah and alcohol users, aged 18–47 years (M = 22.17, SD = 3.66) who completed measures of substance use, drinking motives, and reported demographic information. Structural equation modeling (SEM) was employed to investigate the predictive value of drinking motives on hookah use frequency, age taken into account. Findings showed that hookah use was negatively associated with age (β = − .22, p ≤ . 01). The model regressing hookah use on the four drinking motives provided adequate fit (χ 2 = 314.31, df = 180, p

This study examined adolescent gambling on school grounds (GS+) and how such behavior was associated with gambling-related attitudes. Further, we examined whether GS+ moderated associations between at-risk problem-gambling (ARPG) and gambling behaviors related to gambling partners.Participants were 1988 high-school students who completed survey materials. Demographic, perceptions, attitudes, and gambling variables were stratified by problem-gambling severity (ARPG versus recreational gambling) and GS+ status. Chi-square and adjusted logistic regression models were used to examine relationships among study variables.Nearly 40% (39.58%) of students reported past-year GS+, with 12.91% of GS+ students, relative to 2.63% of those who did not report gambling on school grounds (GS-), meeting DSM-IV criteria for pathological gambling (p0.0001). In comparison to GS- students, GS+ students were more likely to report poorer academic achievement and more permissive attitudes towards gambling behaviors. Weaker links in GS+ students, in comparison with GS-, students, were observed between problem-gambling severity and gambling with family members (interaction odds ratio (IOR)=0.60; 95% CI=0.39-0.92) and gambling with friends (IOR=0.21; 95% CI=0.11-0.39).GS+ is common and associated with pathological gambling and more permissive attitudes towards gambling. The finding that GS+ (relative to GS-) youth show differences in how problem-gambling is related to gambling partners (friends and family) warrants further investigation regarding whether and how peer and familial interactions might be improved to diminish youth problem-gambling severity. The high frequency of GS+ and its relationship with ARPG highlights a need for school administrators and personnel to consider interventions that target school-based gambling.

This study evaluated a decisional balance intervention among heavy drinking undergraduates and compared a nonweighted decisional balance proportion (DBP; Collins, Carey,Otto, 2009) to a participant-weighted DBP with weights based on relative importance of items. We expected: (1) the intervention to decrease drinking compared to control; (2) the weighted intervention to be more effective compared to the nonweighted or control in reducing drinking; and (3) intervention efficacy to be moderated by initial DBP.Participants (N = 162, Mean age = 24.37, SD = 6.81, 27% male) were randomly assigned to an alcohol intervention wherein they were either asked to assign weights of importance to pros and cons (weighted intervention), or not (nonweighted intervention), or to control. Participants completed web-based questionnaires at baseline and again during a one month follow-up assessment.Consistent with expectations, the nonweighted intervention was associated with reduced follow-up weekly drinking, and the weighted intervention was associated with reductions in drinking frequency. Results further indicated that initial decisional balance did not moderate intervention efficacy.Findings suggest that the decisional balance procedure can reduce drinking but there was not compelling evidence for the addition of weights. This study lays the groundwork for enhancing future interventions by increasing empirical knowledge of the role motivation plays in heavy alcohol use.

Socially anxious cannabis users are influenced by cannabis expectancies and normative perceptions. The present study examines the influence of psychosocial factors on cannabis use vulnerability factors as the result of interactions between norms perceptions, social anxiety, and expectancies.Participants were 149 (36.2% female) current cannabis users aged 18-36 (A three-way interaction emerged in the prediction of cannabis cravings. Simple slopes analyses showed that among individuals with perceptions of greater parent approval of cannabis use (higher injunctive norms), social anxiety was associated with greater cannabis craving when expectancies regarding relaxation and tension reduction were greater (Among cannabis users with perceptions of greater injunctive norms, social anxiety was associated with greater cannabis craving when tension reduction expectancies were greater. However, social anxiety was unrelated to cannabis craving when expectances were low. This suggests that cannabis craving among socially anxious adults was greatest when cannabis use was viewed as acceptable and expected to reduce tension, and highlights the importance of considering norms, expectancies, and social anxiety in understanding cannabis-related behaviors.

OBJECTIVE Drinking goals set at treatment onset predict treatment outcome in patients with alcohol use disorders. Yet the cognitive constructs of goal setting and goal attainment are understudied in young adult drinkers. This study sought to examine how the interplay of goal setting and goal attainment during treatment impacts treatment outcome in a sample of young adult heavy drinkers. METHOD Participants were 128 young adult heavy drinkers (Mage = 21.5 years) who participated in a double-blind, placebo-controlled, 8-week efficacy trial of naltrexone plus brief counseling. Participants were not required to be interested in changing their drinking for inclusion. Drinking goals were assessed at baseline, midtreatment, and end of treatment. Outcomes were peak drinking, typical drinking, and drinking frequency. RESULTS Results from PROCESS serial, multiple mediator models showed that midtreatment goal setting and goal attainment collectively predicted peak drinking (b = 0.87, 95% CI [0.40, 1.37]) and drinking frequency (b = 0.66, 95% CI [0.37, 1.06]). Only midtreatment goal setting mediated the relationship between baseline goal setting and typical drinking (b = 0.35, 95% CI [0.10, 0.85]). Participants who set more ambitious drinking goals at baseline were more likely to set subsequent, ambitious goals; more ambitious goals at midtreatment were associated with better treatment outcomes. CONCLUSION Setting initial, ambitious goals led to further ambitious goals, which ultimately contributed to lower levels of drinking. Thus, cognitive processes during treatment may be an important target of intervention efforts. For example, the inclusion of goal-setting exercises during treatment could serve to improve intervention effects. (PsycINFO Database Record

Background: There is a dearth of evidence on the causal effects of different care delivery approaches on health system satisfaction. A better understanding of public satisfaction with the health system is particularly important within the context of task shifting to community health workers (CHWs). This paper determines the effects of a CHW program focused on maternal health services on public satisfaction with the health system among women who are pregnant or have recently delivered. Methods: From January 2013 to April 2014, we carried out a cluster-randomized controlled health system implementation trial of a CHW program. Sixty wards in Dar es Salaam, Tanzania, were randomly allocated to either a maternal health CHW program (36 wards) or the standard of care (24 wards). From May to August 2014, we interviewed a random sample of women who were either currently pregnant or had recently delivered a child. We used five-level Likert scales to assess women’s satisfaction with the CHW program and with the public-sector health system in Dar es Salaam. Results: In total, 2329 women participated in the survey (response rate 90.2%). Households in intervention areas were 2.3 times as likely as households in control areas to have ever received a CHW visit (95% CI 1.8, 3.0). The intervention led to a 16-percentage-point increase in women reporting they were satisfied or very satisfied with the CHW program (95% CI 3, 30) and a 15-percentage-point increase in satisfaction with the public-sector health system (95% CI 3, 27). Conclusions: A CHW program for maternal and child health in Tanzania achieved better public satisfaction than the standard CHW program. Policy-makers and implementers who are involved in designing and organizing CHW programs should consider the potential positive impact of the program on public satisfaction.

Women with a history of sexual assault are at elevated risk for engaging in binge drinking. The aims of the current study are to investigate two types of drinking motives (coping and social) that potentially underlie the sexual assault-binge drinking link in a sample of female college drinkers (N = 691; 37.6% sexual assault prevalence), and to determine the extent to which the relationships between sexual assault history and each type of drinking motive depend on women's assumptions about the controllability of events. Conditional process analysis results indicated that women who experienced sexual assault (vs. those who did not) were more likely to report both coping and social drinking motives, which in turn, were both positively associated with increased binge drinking. Consistent with our hypothesis, results showed the relationship between sexual assault history and coping drinking motives was moderated by perceived controllability of events. Specifically, sexual assault victims reported high coping motives regardless of controllability of events. Nonvictims only reported high coping motives when their perceived controllability of events was low – comparable to coping motives of victims. This integrative approach affords a more comprehensive understanding of the context in which college women's binge drinking occurs, and offers insight into processes that could be targeted in interventions.

International audience; We study the ultrafast structural dynamics, in response to electronic excitations, in heterostructures composed of size-selected Au nanoclusters on thin-film substrates with the use of femtosecond electron diffraction. Various forms of atomic motion, such as thermal vibrations, thermal expansion, and lattice disordering, manifest as distinct and quantifiable reciprocal-space observables. In photoexcited supported nano clusters, thermal equilibration proceeds through intrinsic heat flow between their electrons and their lattice and extrinsic heat flow between the nanoclusters and their substrate. For an in-depth understanding of this process, we have extended the two-temperature model to the case of 0D/2D heterostructures and used it to describe energy flow among the various subsystems, to quantify interfacial coupling constants and to elucidate the role of the optical and thermal substrate properties. When lattice heating of Au nanoclusters is dominated by intrinsic heat flow, a reversible disordering of atomic positions occurs, which is absent when heat is injected as hot substrate phonons. The present analysis indicates that hot electrons can distort the lattice of nanoclusters, even if the lattice temperature is below the equilibrium threshold for surface premelting. Based on simple considerations, the effect is interpreted as activation of surface diffusion due to modifications of the potential energy surface at high electronic temperatures. We discuss the implications of such a process in structural changes during surface chemical reactions.

This study examined marijuana-related cognitions and marijuana use in African-American (AA) and European-American (EA) girls, with the aim of characterizing their interrelationships from early to late adolescence. Identifying differences by race in these relationships would have implications for tailoring interventions to specific subgroups. Data were drawn from the Pittsburgh Girls Study, an urban community sample (56.8% AA, 43.2% EA; n = 2,172) recruited at ages 5-8 years and assessed each year. Cross-lagged panel models were conducted separately by race to identify patterns of association between marijuana use and related cognitions (i.e., intentions to use, positive attitude toward use, positive and negative expectancies) assessed at ages 12-17 years. Results indicated that AA girls consistently reported higher negative expectancies than EA girls and greater intention to use marijuana, but they did not differ from EA girls on positive expectancies. In cross-lagged models, bidirectional effects between negative expectancies and marijuana use were observed in AA and EA girls across all ages, and at most ages for intentions to use, but were largely absent in both groups for positive attitude. Bidirectional effects of marijuana use with positive expectancies were observed only in AA girls at certain ages. Overall, results demonstrate more similarities than differences between AA and EA girls in the longitudinal associations between marijuana-related cognitions and marijuana use. Results highlight the role of negative expectancies as shaping and being shaped by marijuana use. Interventions that target negative expectancies to reduce marijuana use may be useful for AA and EA adolescent girls. (PsycINFO Database Record

The present research examined the impact of cannabis motives on tobacco outcomes.The sample included 403 daily smokers (214 males, mean age 35.24 years). A bifactor model of cannabis motives was examined to determine whether this approach might best elucidate relations between cannabis motives and smoking.Coping motives were associated with reduced barriers for smoking, fewer negative smoking expectancies, and decreased positive reinforcement with respect to smoking. Conformity motives were associated with fewer internal smoking barriers. Expansion motives were associated with more positive reinforcement related to smoking. Enhancement motives were associated with reductions in smoking for appetite/weight control consequences. The general motives variable, comprised of each of the five motives subscales, was associated with more barriers related to tobacco addiction, more external barriers, greater positive reinforcement consequences, and more negative expectancies. Coping motives were negatively associated with quit status, and were positively associated with quit status.Cannabis motives subscales were not uniformly predictive of quit success. Individuals who used cannabis for conformity reasons were more likely to successfully quit smoking, however, individuals who used cannabis for coping reasons were less likely to quit smoking. Thus, those who use cannabis for conformity reasons are less likely to turn to cannabis during times of stress or to relieve tension or anxiety, a view supported by existing literature. This suggests that individuals who use cannabis for coping reasons may represent a population vulnerable to cannabis misuse and problems. Additional work is needed to better understand underlying mechanisms.

Objective Social influences on gambling among adolescents and adults have been well documented and may be particularly evident among college students, who have higher rates of problem and pathological gambling relative to the general population. Personalized normative feedback (PNF) is a brief intervention designed to correct misperceptions regarding the prevalence of problematic behavior by showing individuals engaging in such behaviors that their own behavior is atypical with respect to actual norms. The current randomized controlled trial evaluated a computer-delivered PNF intervention for problem gambling college students. Method Following a baseline assessment, 252 college student gamblers scoring 2+ on the South Oaks Gambling Screen (SOGS) were randomly assigned to receive PNF or attention-control feedback. Follow-up assessments were completed 3 and 6 months postintervention. Results Results indicated significant intervention effects in reducing perceived norms for quantities lost and won, and in reducing actual quantity lost and gambling problems at the 3-month follow-up. All intervention effects except reduced gambling problems remained at the 6-month follow-up. Mediation results indicated that changes in perceived norms at 3 months mediated the intervention effects. Further, the intervention effects were moderated by self-identification with other student gamblers, suggesting that PNF worked better at reducing gambling for those who more strongly identified with other student gamblers. Conclusions Results support the use of PNF as a stand-alone brief intervention for at-risk gambling students. Extending this approach more broadly may provide an accessible, empirically supported gambling prevention option for universities and related institutions.

Background: Home visits by community health workers (CHW) could be effective in identifying pregnant women in the community before they have presented to the health system. CHW could thus improve the uptake of antenatal care (ANC), HIV testing, and prevention of mother-to-child transmission (PMTCT) services. Methods: Over a 16-month period, we carried out a quantitative evaluation of the performance of CHW in reaching women early in pregnancy and before they have attended ANC in Dar es Salaam, Tanzania. Results: As part of the intervention, 213 CHW conducted more than 45,000 home visits to about 43,000 pregnant women. More than 75% of the pregnant women identified through home visits had not yet attended ANC at the time of the first contact with a CHW and about 40% of those who had not yet attended ANC were in the first trimester of pregnancy. Over time, the number of pregnant women the CHW identified each month increased, as did the proportion of women who had not yet attended ANC. The median gestational age of pregnant women contacted for the first time by a CHW decreased steadily and significantly over time (from 21/22 to 16 weeks, P-value for test of trend

Background Substance use is partially driven by habitual processes that occur automatically in response to environmental cues and may be central to users’ identities. This study was designed to validate the Self-Report Habit Index (SRHI) for assessing habitual marijuana, alcohol, cigarette, and e-cigarette use. Methods We examined the SRHI’s psychometrics in separate samples of adult marijuana ( N s = 189;170), alcohol ( Ns = 100;133), cigarette ( Ns = 58;371), and e-cigarette ( N = 239) users. Results A 6-item, single-factor solution evidenced good fit across substances (CFI marijuana/alcohol/cigarettes/e-cigarettes = 0.996/0.997/0.996/0.994, RMSEA = 0.046/0.047/0.067/0.068, SRMR = 0.017/0.017/0.010/0.015) and internal consistency (α = 0.88/0.94/0.95/0.91). The SRHI was scalar invariant for sex and race. However, independent-samples t -tests indicated only that women endorsed stronger habitual e-cigarette use and that men endorsed stronger habitual marijuana use. The SRHI also was scalar invariant by product type in dual-users (cigarettes/e-cigarettes[ N = 371]; alcohol/cigarettes [n = 58]), although differences in habit strength only were observed for cigarettes versus e-cigarettes, with dual-users reporting stronger habitual cigarette use. Finally, the SRHI predicted frequency of marijuana, alcohol, cigarette, and e-cigarette use (n p 2 [marijuana/alcohol/cigarettes/e-cigarettes] = 0.37/0.48/0.31/0.17) and quantity of alcohol and cigarette use (n p 2 = 0.43/0.33). Conclusions The SRHI is a psychometrically sound measure of adults’ habitual substance use. The SRHI detected mean differences by sex and substance type and predicted the frequency of using each substance. Future research should determine if the SRHI is appropriate for use with other substances or age groups (e.g., adolescents), how it relates to task-based, behavioral measures of habit strength, and the degree to which habit predicts the development or maintenance of addiction.

BACKGROUND: African American (AA) girls initiate alcohol use later and drink less than European American (EA) girls, potentially reflecting differences in the development of drinking behaviors. The current study examined alcohol-related cognitions: expectancies, attitudes, and intention to drink, as possible sources of variation by race in alcohol use. The aim of the current study was to characterize the nature and degree of association between these cognitions and use over time and by race in EA and AA girls. METHODS: Data were drawn from the longitudinal Pittsburgh Girls Study (PGS, N=2,450), an urban population-based sample of girls and their caregivers recruited when girls were between ages 5 and 8, and assessed annually through adolescence. Cross-lagged panel models were conducted separately by race (56.2% AA, 43.8% EA) to identify patterns of association between alcohol use and cognitions from ages 12–17 in 2,173 girls. RESULTS: Endorsement of cognitions and use were higher overall in EA than AA girls but the magnitude of cross-lagged path coefficients did not differ significantly by race. In both groups, bidirectional effects emerged between intentions and use, and alcohol use largely predicted cognitions across ages. However, intention to drink was the only alcohol-related cognition that consistently predicted subsequent use (odds ratios ranged from 1.55–2.71). CONCLUSIONS: Although rates of alcohol use and endorsement of cognitions were greater in EA than AA girls, the anticipated racial differences in longitudinal associations between cognitions and use did not emerge, indicating that variation in associations between use and cognitions does not account for the lower prevalence of alcohol use in AA compared to EA girls. Furthermore, our finding that intention to drink is a consistent, robust predictor of subsequent alcohol use suggests the need to investigate potentially modifiable factors that influence intention to drink across racial groups.

Although social networking sites such as Facebook have been touted as creating a global village, there may be a downside to such computer-mediated interactions on user's well-being. One such consequence is that stimuli via computer-mediated interactions may be anxiety-provoking for some users. As such, recent studies have tried to ascertain personality factors and individual differences that are associated with higher anxiety in connection with extensive Facebook use. The current study evaluated the relationships among extraversion, time on Facebook, need for approval, and anxiety among college students (N=280). Results revealed that need for approval significantly moderated the association between extraversion and anxiety. Specifically, individuals higher in extraversion tended to be less anxious, although this was less true for those extraverts who were higher in need for approval. Further, this moderating effect was stronger among extraverts who were high in need for approval and spent more time on Facebook relative to those who spent less time on Facebook. The present research contributes to the emerging literature by providing evidence regarding how personality factors interact with Facebook usage.

Research supports links between marijuana effect expectancies and risky sexual behaviors among marijuana users, but associations between marijuana expectancies and hypersexuality have yet to be investigated. The current study examined links between marijuana lifetime use and hypersexuality among university students. A hierarchical regression adjusting for gender and alcohol use was used to determine the degree to which marijuana use and expectancies accounted for variance in hypersexuality. Marijuana lifetime use and hypersexuality were significantly and positive related. After adjusting for covariates, perceptual and cognitive enhancement expectancies positively correlated with hypersexuality, while tension reduction and relaxation expectancies negatively correlated with hypersexuality.

This study evaluated pet affinity as a buffer between ambivalence over emotional expression (AEE) and social support. AEE occurs when one desires to express emotions but is reluctant to do so and is related to negative psychological outcomes. Individuals high in AEE may have difficulty receiving social support and thus may not gain accompanying benefits. Social support has been associated with positive health outcomes, and pet support is positively associated with human social support. The present study explores the potential protective effect of pet affinity. One hundred ninety-eight undergraduate dog owners completed measures assessing perceived social support, pet affinity, and AEE. AEE was expected to be negatively associated with social support, and pet affinity was expected to buffer the negative effects of AEE on social support. We found that AEE was negatively associated with perceived social support. An interaction between pet affinity and AEE emerged such that the negative association between AEE and social support was weaker among those higher in pet affinity. Thus, at high levels of AEE, those who felt a close connection with their pets reported more perceived social support than those less connected with their pets. Overall, these findings emphasize the potential benefits of pet affinity.

The aim of the present study was to test promising constructs (decisional balance and drinking identity) and their interaction with gender as predictors of risky college drinking. We expected that, consistent with previous work, drinking identity would be positively associated with alcohol consumption and problems. We further expected that drinking identity would be more strongly related to outcomes among individuals scoring low in decisional balance. Additionally, we expect the relationship between drinking identity and alcohol behavior to vary as a function of decisional balance.Participants included 329 undergraduates (M=23.11; SD=5.63; 74.47% female) who met heavy drinking criteria (defined as women who consumed 4 or more drinks per occasion and men who consumed 5 or more drinks per occasion) and completed an online survey comprised of self-report measures.Decisional balance was negatively correlated with both drinking and problems, which partially supported expectations. As expected, drinking identity was positively correlated with drinking and problems. A two-way interaction emerged between drinking identity and decisional balance regarding problems, indicating that drinking identity was associated with more problems, especially among those lower in decisional balance. A three-way interaction between drinking identity, decisional balance, and gender emerged regarding problems such that drinking identity was associated with more problems for those lower in decisional balance and this effect was stronger among men.Findings lend support to the perspective that decisional balance, drinking identity, and gender are all influential factors that are associated with the experience of alcohol problems.

Research has revealed negative associations between religiosity and alcohol consumption. Given these associations, the aim of the current research was to evaluate whether the order of assessing each construct might affect subsequent reports of the other. The present research provided an experimental evaluation of response biases of self-reported religiosity and alcohol consumption based on order of assessment. Participants (N = 301 undergraduate students) completed an online survey. Based on random assignment, religiosity was assessed either before or after questions regarding recent alcohol consumption. Social desirability bias was also measured. Results revealed a priming effect such that participants who answered questions about their religiosity prior to their alcohol consumption reported fewer drinks on their peak drinking occasions, drinking less on typical occasions, and drinking less frequently, even when controlling for social desirability and for the significant negative associations between their own religiosity and drinking. In contrast, assessment order was not significantly associated with religiosity. Results indicate priming religion results in reporting lower, but potentially more accurate, levels of health risk behaviors and that these effects are not simply the result of socially desirable responding. Results are interpreted utilizing several social-cognitive theories and suggest that retrospective self-reports of drinking may be more malleable than self-descriptions of religiosity. Implications and future directions are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

This study examined the relationship between self-reported drinking identity (SRDI), defined as how closely individuals believe drinking is a crucial aspect of their identity (Conner, Warren, Close, & Sparks, 1999), and alcohol use by considering drink-refusal self-efficacy (DRSE) as a potential mediator. Based on previous findings, we expected that SRDI would be negatively associated with DRSE and positively associated with drinking, and that DRSE would be negatively linked with drinking. Further, we expected that DRSE would mediate the association between SRDI and drinking. Participants included 1069 undergraduate students (M age = 22.93 years, SD = 6.29, 76.25% female) from a large southern university who completed computer-based study materials. Gender was associated with SRDI, each of the DRSE subscales, and drinking, indicating that males report greater SRDI, lower DRSE, and increased alcohol consumption. Consistent with expectations, SRDI was negatively linked with DRSE and positively linked with drinking. DRSE subscales were negatively associated with drinking. Further, four measurement models for latent variables were tested for SRDI and each of the three DRSE subscales. Results showed that the emotional relief and social subscales of DRSE mediated the association between SRDI and drinking, however this mediating relationship did not emerge for the opportunistic subscale. Implications of these results are discussed.

This study evaluated the roles of drink refusal self-efficacy (DRSE), implicit drinking identity, and self-awareness in drinking. Self-awareness (assessed by public and private self-consciousness), DRSE, and implicit drinking identity (measured via an implicit association test; IAT) were expected to interact in predicting self-reported drinking. This research was designed to consider mixed findings related to self-awareness and drinking. Hypotheses were: 1) alcohol-related outcomes would be negatively associated with self-awareness; 2) implicit drinking identity would moderate the association between self-awareness and alcohol consumption; and 3) this association would depend on whether participants were higher or lower in drink refusal self-efficacy. Participants included 218 undergraduate students. Results revealed that drinking behavior was not associated with self-awareness but was positively associated with implicit drinking identity. Of the four drinking variables (peak drinking, drinking frequency, drinks per week, and alcohol-related problems), only alcohol-related problems were positively associated with self-awareness. Furthermore, a significant two-way interaction emerged between private (but not public) self-consciousness and drinking identity to predict drinking. Consistent with expectations, three-way interactions emerged between self-awareness, implicit drinking identity, and DRSE in predicting drinking. For participants low in DRSE: 1) high implicit drinking identity was associated with greater drinking frequency when private self-consciousness was low; and 2) high implicit drinking identity was associated with greater drinks per week and peak drinks when public self-consciousness was low. This suggests that alcohol-related IATs may be useful tools in predicting drinking, particularly among those low in self-awareness and DRSE.

Background Home delivery and late and infrequent attendance at antenatal care (ANC) are responsible for substantial avoidable maternal and pediatric morbidity and mortality in sub-Saharan Africa. This cluster-randomized trial aimed to determine the impact of a community health worker (CHW) intervention on the proportion of women who (i) visit ANC fewer than 4 times during their pregnancy and (ii) deliver at home. Methods and findings As part of a 2-by-2 factorial design, we conducted a cluster-randomized trial of a home-based CHW intervention in 2 of 3 districts of Dar es Salaam from 18 June 2012 to 15 January 2014. Thirty-six wards (geographical areas) in the 2 districts were randomized to the CHW intervention, and 24 wards to the standard of care. In the standard-of-care arm, CHWs visited women enrolled in prevention of mother-to-child HIV transmission (PMTCT) care and provided information and counseling. The intervention arm included additional CHW supervision and the following additional CHW tasks, which were targeted at all pregnant women regardless of HIV status: (i) conducting home visits to identify pregnant women and refer them to ANC, (ii) counseling pregnant women on maternal health, and (iii) providing home visits to women who missed an ANC or PMTCT appointment. The primary endpoints of this trial were the proportion of pregnant women (i) not making at least 4 ANC visits and (ii) delivering at home. The outcomes were assessed through a population-based household survey at the end of the trial period. We did not collect data on adverse events. A random sample of 2,329 pregnant women and new mothers living in the study area were interviewed during home visits. At the time of the survey, the mean age of participants was 27.3 years, and 34.5% (804/2,329) were pregnant. The proportion of women who reported having attended fewer than 4 ANC visits did not differ significantly between the intervention and standard-of-care arms (59.1% versus 60.7%, respectively; risk ratio [RR]: 0.97; 95% CI: 0.82–1.15; p = 0.754). Similarly, the proportion reporting that they had attended ANC in the first trimester did not differ significantly between study arms. However, women in intervention wards were significantly less likely to report having delivered at home (3.9% versus 7.3%; RR: 0.54; 95% CI: 0.30–0.95; p = 0.034). Mixed-methods analyses of additional data collected as part of this trial suggest that an important reason for the lack of effect on ANC outcomes was the perceived high economic burden and inconvenience of attending ANC. The main limitations of this trial were that (i) the outcomes were ascertained through self-report, (ii) the study was stopped 4 months early due to a change in the standard of care in the other trial that was part of the 2-by-2 factorial design, and (iii) the sample size of the household survey was not prespecified. Conclusions A home-based CHW intervention in urban Tanzania significantly reduced the proportion of women who reported having delivered at home, in an area that already has very high uptake of facility-based delivery. The intervention did not affect self-reported ANC attendance. Policy makers should consider piloting, evaluating, and scaling interventions to lessen the economic burden and inconvenience of ANC. Trial registration ClinicalTrials.gov NCT01932138, In this cluster-randomized trial in Dar es Salaam, Tanzania, Pascal Geldsetzer & colleagues assessed how a community health worker intervention affected the proportion of women attending antenatal care and delivering their babies at home., Author summary Why was this study done? Along with raising the quality of maternal healthcare services, increasing uptake of antenatal care (ANC) and facility-based delivery is thought to be important to improve both maternal and neonatal health in resource-poor settings. While community health worker (CHW)–led interventions have been proposed to increase uptake of essential maternal care services, there is limited evidence for these interventions from large-scale randomized studies implemented in the routine health system. What did the researchers do and find? We randomized all 60 wards (geographic areas) in 2 of 3 districts of Dar es Salaam, Tanzania, to a CHW intervention—consisting of additional CHW supervision, CHW-led identification of newly pregnant women in the community, and CHW follow-up at home for those who missed an ANC or prevention of mother-to-child HIV transmission (PMTCT) appointment—or to the standard of care (counseling visits by CHWs to PMTCT patients only). We found no difference between study arms in self-reported ANC underutilization (attending ANC fewer than 4 times and not visiting ANC in the first trimester) but the intervention almost halved the probability of women reporting having delivered at home (3.9% in the intervention arm versus 7.3% in the standard-of-care arm). In a nested mixed-methods study, we found that a likely reason for the CHW intervention’s lack of effect on ANC utilization was that provision of information, counseling, and reminders by CHWs was insufficient to change women’s perception that the relatively high transport costs, lost time from work, and inconvenience of earlier and more frequent ANC attendance outweigh its benefits. What do these findings mean? The CHW intervention appears to have been effective in moving towards universal coverage of facility-based delivery in this population that already has high uptake of facility-based delivery. However, the CHW intervention was insufficient to improve the timeliness and frequency of ANC attendance. The main limitation of this study was that the outcomes were assessed through self-report only. Policy makers should consider piloting, evaluating, and scaling CHW interventions aimed at reducing the economic burden and inconvenience of ANC attendance, which could include shifting ANC tasks from nurses at healthcare facilities to CHWs in the community to decrease the number of required healthcare facility visits for ANC.

This study evaluated benefit finding as a moderator of the relationship between spiritual and religious attitudes and drinking. Previous research indicates that undergraduates who drink heavily experience negative alcohol-related consequences. Literature also suggests that spirituality and religiosity (S/R) are protective against heavy drinking (e.g., Yonker, Schnabelrauch, & DeHaan, 2012) and that finding meaning, which is conceptually related to benefit finding, is negatively associated with alcohol use (e.g., Wells, 2010). Seven hundred undergraduate students completed the study materials including measures of drinking, benefit finding, and S/R. Based on previous research, we expected that S/R and benefit finding would be negatively associated with drinking. Furthermore, we expected that benefit finding would moderate the association between S/R and drinking, such that S/R would be more negatively associated with drinking among those higher in benefit finding. Consistent with expectations, a negative association between S/R and drinking was present, and was stronger among those high in benefit finding. These findings extend previous research by demonstrating that the protective effect of S/R on drinking appears to be particularly true among those who find benefit following stressful experiences. This study extends previous research showing that S/R is negatively associated with drinking by evaluating benefit finding (measured via the Post-Traumatic Growth Inventory; Tedeschi & Calhoun, 1996) as a potential moderator of the relationship between S/R and drinking. This study contributes to the alcohol literature seeking to understand and identify individual factors in drinking and determine how S/R and benefit finding relate to drinking.

Predicting hazardous drinking in college students continues to be a serious priority. Emerging evidence suggests that implicit measures may offer additional insight in predicting unique variance in alcohol outcomes. Implicit drinking identity, in particular, may be a powerful predictor of alcohol use. The current study examined the predictive validity of three alcohol-related associations (e.g., drinking identity, alcohol approach, and alcohol cope) using adaptations of the Implicit Association Test (IAT) in a sample of 243 undergraduates. Confirming previous findings, drinking identity associations were the most consistent predictor of alcohol consumption and alcohol problems. They were the only associations that were unique predictors of alcohol use after controlling for other implicit associations. In comparison, alcohol cope and alcohol approach associations were weak but consistent predictors of alcohol consumption and alcohol problems. Although positively correlated with all drinking outcomes, neither set of associations predicted unique variance in the drinking outcomes when all implicit associations were included in the same model. Collectively, these results extend previous findings that implicit drinking identity may be a uniquely powerful tool for predicting alcohol outcomes and a potential target for clinical intervention and prevention efforts.

This study extends previous examinations of social influences and marijuana use in considering how heavy marijuana users view themselves relative to their peers. We were specifically interested in evaluating whether (a) heavy-using marijuana users would identify more strongly with other users than with typical students, (b) identification with other marijuana users would be more strongly associated with own use, and (c) the association between perceived norms and marijuana use would be moderated by identification with peers.Participants were 107 heavy (five or more times per month) marijuana users who completed an online survey assessing perceived norms for marijuana use, identification with typical students and other marijuana-using students, and marijuana use (frequency of use, joints per week, and hours high).Participants unexpectedly identified more strongly with typical students rather than with other marijuana-using students. Identification with other marijuana users was, however, associated with more use. In addition, perceived norms were associated with more use but primarily among those who identified more with other users but not with typical students.Heavy marijuana users may be reluctant to identify themselves as users and may prefer to think of themselves as typical students. This may provide clinical opportunities to highlight discrepancies. In addition, identification with other users and lack of identification with typical students may be risk factors for heavier use and good indicators of candidacy for norms-based interventions. In sum, the present findings extend our understanding of the influence of social identity among young adult marijuana users and suggest novel directions for intervention strategies.

This study evaluated self-consciousness as a moderator of the relationship between social drinking motives and alcohol use. Participants included 243 undergraduate students who reported alcohol use, alcohol-related problems, self-consciousness, and social motives. We expected that social drinking motives, private self-consciousness, and public self-consciousness would be positively associated with drinking and that this relationship would be moderated by self-consciousness. Specifically, we expected this relationship to be stronger for people lower in private self-consciousness, based on decreased awareness about their internal states. In addition, we expected that the relationship between social motives and drinking would be stronger among those who were higher in public self-consciousness, given their focus on the self as a social object. Consistent with expectations, the associations between social motives and peak drinking and drinks per week were more strongly associated among those lower in private self-consciousness. However, inconsistent with expectations, the relationship between social motives and drinking was stronger among those who were lower, rather than higher, in public self-consciousness. Overall implications of these research findings extend previous research emphasizing the importance of considering social influences in etiology and prevention of drinking. Moreover, while social motives are a consistent predictor of drinking among young adults, this is not universally true. This study contributes to social cognitive literature seeking to understand and identify individual factors related to drinking and their application to the adaptation of existing intervention approaches.

The present research was designed to evaluate self-determination theory as a framework for integrating factors associated with intimate partner violence (IPV) perpetration. The proposed model suggests that childhood exposure to parental violence may influence global motivational orientations which, in turn, results in greater cognitive biases (overestimating the prevalence of IPV and justification of IPV) which, in turn, contribute to an individual's decision to use abusive behavior. Participants included 124 men who had engaged in abusive behavior toward an intimate partner. Results provided reasonable support for the proposed model and stronger support for a revised model suggesting that controlled orientation, rather than autonomy orientation, appears to play a stronger role in the association between childhood exposure to parental violence and cognitive biases associated with abusive behavior.

Objectives The present study assessed combinations of spirituality/religiosity (S/R), a known protective factor against heavy drinking, with drinking motives, and alcohol-related ambivalence to better understand how these factors interrelate and are associated with drinking and alcohol-related problems. Methods Participants were 241 heavy drinking undergraduate students (81.74% female; M age = 23.48 years; SD = 5.50) who completed study questionnaires online. Results Coping, enhancement, and conformity drinking motives were associated with greater alcohol use and problems, however there were no main effects of either ambivalence or S/R on alcohol outcomes. S/R interacted with ambivalence with respect to drinking and problems. S/R also interacted with conformity drinking motives with respect to drinking and problems. Further, ambivalence interacted with conformity drinking motives regarding problems. Three-way interactions emerged between ambivalence, S/R, and drinking motives (social, coping, and enhancement motives) regarding drinking and problems. Results show that individuals at highest risk for problematic drinking are those who more strongly endorse drinking motives, are low in S/R, and high in ambivalence. Conclusions Findings supported hypotheses and provide support for clusters of individual difference factors that put heavy drinking college students at higher risk for problematic drinking. These examinations have practical utility and may inform development and implementation of interventions and programs targeting alcohol misuse among heavy drinking undergraduate students.

The present study tested whether coping motives for cannabis use moderate the effect of negative expectancies on cannabis use.Participants were 149 (36.2% female, 61.59% non-Hispanic Caucasian) current cannabis users aged 18-36 (M = 21.01, SD = 3.09) who completed measures of cannabis-related expectancies and motives for use. Hierarchical multiple regressions were employed to investigate the predictive value of the interaction between negative expectancies and coping motives on cannabis use outcomes.Results revealed interactions between negative expectancies and coping motives with respect to past 90 day cannabis use frequency and cannabis problems. Global negative effects expectancies were associated with less frequent cannabis use, particularly among those with fewer coping motives. However, negative expectancies were related to more cannabis problems, particularly among those with higher coping motives.These results suggest it may be advisable to take coping motives into account when addressing expectancies among cannabis users.

The current study investigated whether religious coping would moderate the association between ambivalence over emotional expression (AEE) and depressive symptoms and anxiety symptoms such that the positive relationship between AEE and depressive symptoms and anxiety symptoms would be weaker among those higher in religious coping. Three-hundred and fifty-two undergraduates (M age=23.51 years, SD=6.80; 84.4% female) completed study materials. Contrary to expectations, results revealed a significant interaction between religious coping and AEE such that religious coping exacerbated the relationship between higher AEE and distress symptoms. The implications of this study suggest that religious coping may not be an ideal coping mechanism for individuals with high levels of AEE. These results indicate the need to further examine the role of AEE in religious coping, and have potential implications for clinicians, healthcare professionals, and religious mentors who may promote the use of religious coping in treatment.

Objective: We examined behavioral and cognitively-based quit processes among concurrent alcohol and tobacco users and assessed whether smoking and drinking were differentially influenced. Method: Participants were 200 treatment-seeking smokers (37.50% female; Mage=30.72; SD=12.68) who reported smoking an average of 10 or more cigarettes daily for at least one year. Results: Barriers to cessation (BCS) and reasons for quitting (RFQ) were generally correlated with substance use. BCS moderated the relationship between quit methods and cigarette use such that quit methods were negatively associated with smoking, particularly among those with more BCS. RFQ moderated the association between quit methods and cigarette use such that quit methods were negatively linked with smoking among those with fewer RFQ, but positively linked with smoking among those with more RFQ. Two 3-way interactions emerged. The first 3-way indicated that among individuals with fewer RFQ, quit methods was negatively associated with smoking, and this was strongest among those with more BCS. However, among those with more RFQ, smoking and quit methods were positively associated, particularly among those with more BCS. The second 3-way showed that among those with fewer RFQ, quit methods was negatively linked with drinking frequency, and this was strongest among those with more BCS. However, among those with fewer BCS, drinking and quit methods were positively linked. Conclusion: The relationship between behavioral and cognitively-based quit processes and substance use is not straightforward. There may be concurrent substance-using individuals for whom these processes might be associated with increased substance use.

Understanding the criminogenic risk factors and treatment needs of juvenile drug offenders is important because of the myriad negative outcomes that befall juveniles that are involved in drugs. A widely used juvenile risk assessment tool, the Youth Level of Service/Case Management Inventory (YLS/CMI) was utilized to explore criminogenic risk factors and treatment needs to predict recidivism. Demographic differences between drug and nondrug offenders were also examined. Results suggested that of the eight YLS/CMI domains, the substance abuse domain was not predictive of recidivism for juvenile drug offenders. However, peer relationships and attitudes significantly predicted future recidivism, suggesting that case planners should pay particular attention to these domains when designing a treatment plan for this group. Cox Regression Hazard Modeling was also used to estimate risk for recidivism among juvenile drug offenders as compared to other juvenile offenders. Results revealed that while juvenile drug offenders had a significantly higher score for substance use, they were not more likely to recidivate than nondrug offenders. Implications are discussed.

Background: The current study sought to evaluate the main and interactive effect of health perceptions, smoking quit attempt history, and readiness to change with respect to depressive symptoms among college student smokers. Method: The present data came from baseline data from a randomized trial and included 495 undergraduate students (Mage=23.84, SD=4.92, 47.47% female) who reported smoking at least 1 cigarette per day. Results: A three-way interaction emerged between smoking quit attempt history, health perceptions, and readiness to change with respect to depressive symptoms. Quit attempt history was positively associated with depressive symptoms, particularly among individuals high in readiness to change if they perceived their health as poorer relative to peers; however, quit attempt history was negatively associated with depressive symptoms, particularly among individuals high in readiness to change if they perceived their health as comparable as or better than that of their peers. Conclusion: These findings support the assertion that readiness to change, quit history and perceived health interact in a dynamic way to confer greater risk for poor outcomes including smoking(e.g., cessation failure) and psychological-related outcomes (e.g., increased depressive symptoms). As such, development of informed interventions and programs targeting readiness to change to improve quit history and perceptions of health may provide unique benefit.
