Background: Coronavirus disease 2019 (COVID-19) vaccine hesitancy has remained a significant concern among adults worldwide. However, not much is known about parental vaccine hesitancy for getting children vaccinated for COVID-19 in the U.S. Thus, the purpose of this study was to conduct a national assessment of parents’ preferences for COVID-19 vaccination of children using the evidence-based Multi-Theory Model (MTM) and explore the predictors of vaccine hesitancy. Methods: To participate in this study, a national random sample of parents (n=263) took a valid and reliable online questionnaire based on the MTM. Independent samples t test, chi-square test, multiple logistic regression was utilized to analyze data. Results: More than two-fifths (42%) of the participating parents were not willing to get their children vaccinated for COVID-19. Parental vaccination status, booster dose acceptance, education, and political affiliation were significant predictors of willingness to get children vaccinated for COVID-19. In the multiple logistic regression analyses, behavioral confidence and participatory dialogue (i.e., perceived advantages versus disadvantages) were statistically significant predictors of COVID-19 vaccination hesitancy for children among the participating parents. Conclusion: Given the multiple factors that were found influential in parental hesitancy for COVID-19 vaccination among children, multimodal and evidence-based interventions are needed to increase the uptake of COVID-19 vaccines among children by influencing the parents’ perceptions, increasing their confidence, dispelling misinformation, and reducing constraints for vaccination. Such interventions should emphasize communication and messaging that is truthful, interactive, scientifically correct, and to be delivered in a variety of community-based settings.

To enhance children's health, the promotion of nutrition literacy in school is vital as it helps prevent the development of health conditions and diseases and maintain healthy lifestyles. Taiwan features the top highest ratio of convenience stores per population density. Convenience stores, an increasingly popular dining place, were linked to the development of eating behavior and body weight issues in children. An eight-week classroom-based nutrition intervention, employing the Traffic Light Diet as a framework, targeting children's perception of and intention to visit the convenience store was implemented. The study conducted a quasi-experimental pretest-posttest research design with a comparison group. A total of 49 students participated in the study, with 25 in the intervention and 24 in the comparison group. Data were collected by utilizing surveys, interviews, and observations. The study's findings demonstrated the positive trajectory of the impact of this intervention on increasing food-and-nutrition-related knowledge and improving healthier diet choices at convenience stores among children. One main theme was identified in coding interviews: parent involvement in meal preparation may reduce convenience store use and increase consumption of vegetables among children. Assessing the influence of parental support for healthy dietary choices, eating nutritious foods at home, and involving the family in meal preparation is an area for future research.

Adolescents from minority groups are particularly susceptible to poor oral hygiene behaviors, including lack of daily flossing. This cross-sectional study aimed to conduct an exploratory behavioral research to identify evidence-based (theory-based) approaches to promote flossing behavior among African American/Black and Latinx/Hispanic (minority) adolescents. A 39-item psychometrically valid web-based questionnaire was used to collect responses from a nationwide sample of minority adolescents aged 10–17 years residing in the United States. The data were analyzed using bivariate and multivariate statistical methods. Of 520 minority adolescents (260 African American/Black and 260 Latinx/Hispanic adolescents), the proportion of flossing was nearly equally split in the sample. A significantly higher proportion of minority adolescents who were flossing had access to floss as opposed to those who were not flossing (86.8% vs. 69.8%, p < 0.001). A significantly higher proportion of minority adolescents who were not flossing did not visit the dentist over the past year as opposed to those who floss (25.2% vs. 14.7%, p < 0.001). Among the participants who were not flossing, gender, grade level, instruction in school regarding flossing, and multi-theory model (MTM) of health behavior change constructs were the significant predictors (p < 0.001) of initiating and sustaining flossing. The findings of this study will serve as baseline data for developing and evaluating effective evidence-based interventions using the MTM.

Decades of research have documented post-traumatic stress disorder (PTSD) symptoms in war veterans. Current treatment options for PTSD are unappealing as they either require re-exposure to the traumatic event or medications that are greatly impacted by comorbidities. Meditation-based interventions are a promising alternative. However, there is a dearth of research examining their impact.The purpose of this study was to examine meditation-based interventions tested for efficacy in treating PTSD among veterans and provide collective evidence.Authors searched the MEDLINE and CINAHL databases for relevant studies using the following inclusion criteria: (1) published in peer-reviewed journals; (2) conducted between January 2014 and July 2020; (3) described the evaluation of interventions; and (4) incorporated quantitative or mixed methods.United States.U.S. Veterans.A total of 15 studies (ten articles) met the inclusion criteria. Four tested Transcendental Meditation (n = 4), three tested Mantra Meditation (n = 3), two tested Mindful Meditation (n = 2), one tested Breathing-based Meditation (n = 1), one tested Mindfulness-based Exposure Therapy (n = 1), one tested Cognitively-based Compassion Training Meditation (n = 1), one tested Mantra Meditation and Mindfulness-based Treatment (n = 1), one tested Mindfulness-based PTSD Treatment (n = 1), and one tested Primary Care Brief Mindfulness Program (n = 1). The most common duration was 8 weeks (n = 8) and the most common evaluation design was the randomized controlled trial (n = 10). The most common outcome measure was the Clinician Administered PTSD Scale (CAPS) (n = 12).All interventions reported improvements in PTSD symptoms. Based on this review, meditation-based therapy is a promising approach for managing PTSD, particularly among veterans resistant to trauma-focused therapies. Randomized control trials with large sample sizes that apply CAPS as their primary outcome measure, and take into account effect size, attrition rates, and blinding are recommended for further research.

While emerging studies have demonstrated the benefit of exercise in Substance Use Disorder (SUD) recovery outcomes, lack of motivation to engage in exercise has been indicated as one of many perceived barriers that contribute to low recruitment and adherence rates in SUD treatment. The current study aimed to explore participants’ perceptions of attending a supervised exercise program (boot camp workouts, walking/running practice, and a race event) while in treatment for SUD. A total of 109 participants were recruited to a 14-week exercise training program and 61 chose to participate in, and completed, a race at the close of the program. Interviews were conducted during weeks 6 through 14 and data were examined using Thematic Analysis. Three main themes were identified: (1) pushing forward recovery through running, (2) gaining a sense of achievement by crossing the finish line, and (3) building a sense of belonging in the program. Implications for SUD recovery programs are discussed.

Background Children from disadvantaged backgrounds are more apt to experience lower availability of nutritious foods, lack opportunities to exercise, and lack access to recreational facilities, and thus, are more likely to be obese and at greater risk for developing chronic diseases. We review school health education programs' impact on physical activity behaviors among disadvantaged students. Methods The inclusion criteria of the study were articles: published in English with full text between 2011 and 2017; focused on school health education programs for disadvantaged school-aged students; assessed programs including a physical activity component; examined school-aged children and adolescents' physical activity behaviors; and assessed programs with comparison groups. Results There were 13 studies matching inclusion criteria in this review. The results of this review indicated that school-based health education programs which included culturally appropriate physical activity, parent involvement, and enhanced student motivation and choice of activities appeared to increase physical activity levels among disadvantaged school-aged students. Health education programs should also emphasize behavioral change skills, such as goal setting and self-motivation, to positively impact on students' physical activity behaviors. Conclusions School-based health education programs may help increase access to physical activity among disadvantaged populations.

Separation from parents is a key aspect of adolescent development and has been linked to a variety of important mental and behavioral health outcomes. Separation-individuation measures were developed in the United States and have been used in Asian contexts. However, no cross-cultural studies have demonstrated that measures of separation-individuation tap the same domains across Asian and American adolescents. This article describes two studies conducted to develop and initially validate a scale for measuring adolescent separation-individuation. Study 1 (n = 300) developed a Brief Measure of Separation-Individuation (BMSI) using Confirmatory Factor Analysis and Item Response Theory. The result was a 32-item BMSI that provided comparable test information to the original 148-item measure. Study 2 examined the BMSI for measurement invariance and convergent validity across U.S. and Taiwanese samples (ns = 231 and 323). Findings suggest that functional independence, attitudinal independence, and emotional independence may be culturally invariant separation-individuation constructs. However, conflictual independence seems to be more culturally dependent in that its items were only partially scalar invariant and it was only loosely related to the other separation-individuation factors. Findings are consistent with previous research that recommended against using total scores for the PSI (i.e., scoring a single separation-individuation dimension). This study suggests the BMSI holds promise as a brief measure of separation-individuation that can be used in cross-cultural research.

Measurement invariance is a statistical property of an instrument (e.g., a test or questionnaire) indicating that it measures the same construct(s) in the same way across subgroups of respondents. Given the extensive research in evolutionary psychology devoted to sex differences and cross-cultural comparisons, measurement invariance testing is crucial not only because it protects against erroneous inference, but also because it provides nuanced information about group similarities and differences. In this article, we draw attention to the importance of, and present a beginner’s guide to, measurement invariance testing. We define measurement invariance formally, summarize sources of non-invariance and the rationale for measurement invariance testing, and describe the two frameworks typically used to test for invariance. We then review evidence of a relative lack of measurement invariance testing in evolutionary psychology and conclude with a case example with MPlus syntax. By testing for measurement invariance, researchers studying evolutionary psychology can strengthen their field and enhance the popularity of their constructs in other disciplines.

The incremental theory of intelligence has been identified as a strong predictor of students’ learning motivation. Recent research has suggested various moderators of its effect. The present study ...

Measurement invariance is crucial in counseling research and assessment because it ensures that scores have the same meanings across treatment conditions, time points, or diverse populations. We conducted a review and content analysis of articles that reported invariance testing and were published in selected counseling journals between 2010 and 2019 (N = 1165). Findings suggest a small proportion of published invariance tests (2.8%) had been undertaken by counseling researchers. We found that the majority of the articles that reported invariance testing in counseling research addressed gender and race/ethnicity. Implications for future research, counselor educator training, and clinical practice are discussed.

Globally, breast cancer is the most common malignancy affecting women. The incidence of breast cancer has been growing among Asian American women. Mammography is a screening procedure that provides early diagnosis for the timely treatment to reduce premature mortality due to breast cancer. However, there are no national data available that summarize the rates of mammography screening among Asian American women. Some small-scale studies have reported low rates of mammography uptake among Asian American women. This cross-sectional study utilized the fourth-generation, multi-theory model (MTM) of health behavior change to explain the correlates of mammography screening among Asian American women between the ages of 45–54 years. A 44-item instrument was evaluated for face, content, and construct validity (using structural equation modeling) and reliability (Cronbach’s alpha) and administered electronically to a nationally representative sample of Asian American women (n = 374). The study found that Asian American women who have had received mammograms in the past 12 months as per recommendations, all three constructs of MTM, namely, participatory dialogue (β = 0.156, p &lt, 0.05), behavioral confidence (β = 0.236, p &lt, 0.001), and changes in the physical environment (β = 0.426, p &lt, 0.001) were statistically significant and crucial in their decision to initiate getting a mammogram, accounting for a substantial 49.9% of the variance in the decision to seek mammography. The study also found that the MTM constructs of emotional transformation (β = 0.437, p &lt, 0.001) and practice for change (β = 0.303, p &lt, 0.001) were significant for maintaining the repeated behavior of getting annual mammograms and were responsible for 53.9% of the variance. This evidence-based study validates the use of MTM in designing and evaluating mammography screening promotion programs among Asian American women aged 45–54 years.

Psychoactive substance use has been typical of most traditional and modern societies and is maintained in the population despite the potential for abuse and related harms, raising the possibility that it (or its underlying causes) confers fitness benefits that offset its costs. Although it seems plausible that psychoactive substances have facilitated survival among ancestral and modern humans, it is not clear that this enhancement has translated into Darwinian fitness through mating and ultimately reproductive success. In the current study, we discuss potential mechanisms by which substance use might make unique contributions to mating success, attend to the possibility that the effects between substance use and mating success are instead confounded, and use structural equations and nationally representative data to determine whether these effects are more likely causal or spurious. Our findings indicate that once we know participants' scores on "third" variables at each round in early young adulthood, their substance use gives us little additional information about their current prospects for acquiring sexual partners and no additional information about of their future prospects. Thus, if adaptations for substance use evolved, their adaptive value does not seem to be found in mating success.

Consuming 5 or more cups of fruits and vegetables (F & V) per day or 400 g/day for adults is advocated by most health authorities and has short-term and long-term health benefits. There have been numerous studies examining dietary behaviors among different US populations; however, the literature on F & V consumption behavior among Asian Americans (AAs) is sparse. AAs constitute a diverse group and as their population continues to grow in the US; there is a greater need to examine the health practices of AAs and their constituent subgroups. The study aimed to conduct a thematic analysis based on a scoping review of the peer-reviewed published literature over the past 15 years targeting F & V consumption among AAs. The thematic analysis was organized around the prevalence, consequences, determinants, and interventions ( n = 33). AAs consuming recommended servings of F & V ranged from 0.5% to 20%. Correlations between the consumption of F & V and Body Mass Index (BMI) and other chronic diseases were reported as negative and significant associations were noted between F & V intake and self-reported health. There was only 1 intervention that was conducted with this behavior in only 1 small subgroup of this target population. There is an urgent need to study F & V consumption behavior among different AA subgroups as well as to design culturally appropriate theory-based efficacious F & V promotion interventions for them.

Research suggests that fast life history strategy (LHS) may be a primary driver of substance use among young adults. However, a recent study reported that (a) young adult fast LHS did not subsume all theorized indicators of LHS during this period and (b) fast LHS among parents did not predict young adult fast LHS or liability for use of common substances. In this study, we used structural equations and national data to test whether these findings generalized to adolescence. In addition, given that LHS and substance use share genetic and neuropsychological bases, we examined whether fast LHS could explain the developmental stability of substance use. Overall, our results extend the findings discussed above and suggest that fast LHS fully explains the developmental stability of substance use among youth. We discuss implications for life history models, research applying life history theory and substance use, and substance abuse prevention and treatment.

Childhood obesity and overweight are among the most serious public health challenges in Taiwan. Moderate daily physical activity, limiting screen viewing, drinking more water, and consuming adequate fruits and vegetables are modifiable and particularly important for preventing childhood obesity. Self-efficacy, expectations, and self-control were used to predict each of the four behaviors. A valid and reliable instrument was administered to 222 upper elementary students. Minutes of physical activity were predicted by self-efficacy and self-control to exercise (R2 = 0.111). Hours of TV watching were predicted by self-efficacy of watching less than 2 hour of TV (R2 = 0.136). Glasses of water consumed were predicted by self-efficacy for drinking water and age (R2 = 0.093). Servings of fruits and vegetables consumed were predicted by self-efficacy of eating fruits and vegetables (R2 = 0.089). This research provided useful guidance based on social cognitive theory for building prevention programs specific to th...

The current study provided a review of evidence-based yoga interventions’ impact on smoking cessation. The researchers reviewed articles obtained from MEDLINE (PubMed), EBSCOHOST, PROQUEST, MEDINDIA, CINAHL, Alt HealthWatch, and AMED databases. Inclusion criteria were as follows: ( a) study published between 2004 and 2013, ( b) study published in English language, ( c) study used yoga-based interventions, ( d) study involved smokers with varying level of smoking, ( e) study used any quantitative design, and ( f) study had physiological and/or psychological outcomes. A total of 10 studies met the inclusion criteria. Designs were 2 pre–post tests and 8 randomized controlled trials. Majority of the interventions were able to enhance quitting smoking rates in the participants under study. Yoga-based interventions hold promise for smoking cessation. Some of the limitations include short follow-up measurements and short duration of intervention.

Many published studies have employed the Mini-K to measure a single fast–slow life history dimension. However, the internal structure of the Mini-K has not been determined and it is not clear that a single higher order K-factor fits the data. It is also not clear that the Mini-K is measurement invariant across groups such as the sexes. To establish the construct validity of K as well as the broader usefulness of applying life history theory to humans, it is crucial that these psychometric issues are addressed as a part of measure validation efforts. Here we report on three studies that used latent variable modeling and data drawn from two college student samples ( n s = 361 and 300) to elucidate the psychometrics of the Mini-K. We found that (a) the Mini-K had a six dimensional first-order structure, (b) the K-factor provided a parsimonious explanation of the associations among the lower order factors at no significant cost to fit, (c) the Mini-K measured the same K-factor across the sexes, (d) K-factor means did not have the same meaning across the sexes and thus the first-order factors should be used in studies of mean sex differences, and finally, (e) the K-factor was only associated with environment and aspects of mating competition in females. Implications and future directions for life history research are discussed.

This study tested whether life history strategy (LHS) and its intergenerational transmission could explain young adult use of common psychoactive substances. We tested a sequential structural equation model using data from the National Longitudinal Survey of Youth. During young adulthood, fast LHS explained 61% of the variance in overall liability for substance use. Faster parent LHS predicted poorer health and lesser alcohol use, greater neuroticism and cigarette smoking, but did not predict fast LHS or overall liability for substance use among young adults. Young adult neuroticism was independent of substance use controlling for fast LHS. The surprising finding of independence between parent and child LHS casts some uncertainty upon the identity of the parent and child LHS variables. Fast LHS may be the primary driver of young adult use of common psychoactive substances. However, it is possible that the young adult fast LHS variable is better defined as young adult mating competition. We discuss our findings in depth, chart out some intriguing new directions for life history research that may clarify the dimensionality of LHS and its mediation of the intergenerational transmission of substance use, and discuss implications for substance abuse prevention and treatment.

This study used structural equations modeling and undergraduate student data to examine the effects of reward and threat sensitivities on substance use, along with the extent to which impulsivity explained these effects. Our results suggest that impulsivity may translate inversely related reward and threat sensitivities into substance use, completely mediate the effect between threat sensitivity and substance use, and partially mediate the effect between reward sensitivity and substance use. Our results also suggest that individuals with a combination of higher levels on both reward and threat sensitivities may be most impulsive and vulnerable to heightened substance use. We discuss implications for research at the interface of personality and substance use and also substance abuse prevention and treatment.

Several investigations have shown that the risk of childhood overweight and obesity may be associated with excessive gestational weight gain (GWG), but the study samples were limited and results were mixed; hence we conducted this meta-analysis to assess the explicit association between them and present evidence.We searched PubMed, EMbase, Ovid, Web of knowledge and Cochrane library for relevant studies. Bibliographies from retrieved articles were also manually searched. Cohort studies that presented results by OR or RR with 95 % CI for the association of maternal excessive GWG and child overweight/obesity were included. The pooled estimates were calculated by fixed-effect model or random-effect model according to the heterogeneity.Twelve cohort studies were identified, and the combined OR of excessive GWG and childhood overweight/obesity was 1.33 (95 % CI 1.18-1.50) with evidence of heterogeneity (P = 0.000, I (2) = 71.1 %). Adjustment of maternal BMI, investigation area, age of children, research type, and omission of any single study had little effect on the pooled estimate. After eliminating the effect of publication bias by trim and fill analyses, the result still remained statistically significant (OR 1.21, 95 % CI 1.05-1.40).This meta-analysis suggests that the risk of childhood overweight/obesity is significantly associated with excessive gestational weight gain.
