Introduction: The extant Alcohol's Harms to Others (AHTO) literature is largely comprised of reports from victims. We investigated AHTO from perpetrators' perspectives, including how harms were associated with individual characteristics, and alcohol quantities consumed during the perpetration incident. Methods: Participants (N = 2932) were 14–19 years old, recruited primarily through social media and screened as risky drinkers. They completed face‐to‐face (n = 594) or self‐administered (n = 2338) surveys. They self‐reported whether during their last risky drinking session (LRDS) they had perpetrated any verbal abuse, physical abuse or property damage. A multinomial logistic regression examined whether nine factors were associated with perpetrating zero, one or 2+ categories of AHTO. Results: Eleven percent (n = 323) reported perpetrating at least one form of AHTO (7.5% verbal, 1.9% physical and 4.6% property). Perpetration of AHTO at LRDS was uniquely associated with: younger age, male gender, experiences of childhood physical punishment, greater perpetration incident‐specific drinking, concurrent illicit drug use, and less frequent use of safety strategies while drinking in the past 12 months. Controlling for the other variables, an increase of six Australian standard drinks (60 g of alcohol) increased the odds of perpetration by 15% [95% confidence interval (CI) adjusted odds ratio (AOR) 1.08, 1.23], and an increase of 15 Australian standard drinks increased the odds by 42% (95% CI AOR 1.20, 1.69). Discussion and Conclusions: Individual characteristics, larger quantities of alcohol consumed, and a disinclination to practice harm reduction amplified risk of AHTO perpetration. This has implications for health promotion and risk prevention/reduction strategies. [ABSTRACT FROM AUTHOR]

Issue addressed: Underage drinkers most commonly source alcohol from older peers. However, few studies have examined older peers' supply‐related beliefs and motivations. Methods: A sample of 270 risky drinkers aged 18‐19 years were interviewed in Australia where the legal purchase age is 18. They were asked about their provision to underage friends, awareness of secondary supply legislation (intended to prohibit such supply) and 24 psycho‐legal beliefs around supply. Results: Half (49%) provided alcohol to a 16‐ to 17‐year‐old friend to drink at a party they were both attending at least twice a year. Three‐quarters reported provision was okay so long as the recipient(s) were in a safe environment, and 46% reported "everyone gives alcohol to teenagers if they are in a safe environment." There was significantly higher agreement that "my friends would think I was mean if I did not give alcohol to a friend under the age of 18" (37%), compared to "my friends would think I was uncool if I did not give alcohol to a friend under the age of 18" (26%). Two thirds (69%) felt more responsible for an underage friend's safety if they provided the alcohol. A multivariate logistic regression revealed supply was more likely if the supplier: was aged 18 compared to 19 (95% CI OR: 1.57, 4.84), male (1.06, 3.27), of a higher SES quintile (1.08, 1.80) and believed alcohol supply to minors was morally acceptable (1.01, 1.33) and normal (1.04, 1.38). Knowledge of regulatory strategies (68%) designed to prevent supply to minors, and their perceived deterrent value did not significantly impact supply. Conclusions: Supply of alcohol to underage peers was perceived as morally and socially acceptable in a group of 18‐ to 19‐year‐old risky drinkers. So what?: Opportunities include harm reduction initiatives that prioritise caring responsibilities towards friends, as opposed to relying on external enforcement measures alone.

Introduction and Aims: Alcohol misuse and depressed mood are common during early adolescence, and comorbidity of these conditions in adulthood is associated with poorer health and social outcomes, yet little research has examined the co-occurrence of these problems at early adolescence. This study assessed risky and protective characteristics of pre-teens with concurrent depressed mood/early alcohol use in a large school-based sample.Design and Methods: School children aged 10-14 years (n = 7289) from late primary and early secondary school classes in government, Catholic and independent sectors participated with parental consent in the cross-sectional Healthy Neighbourhoods Study. Key measures included depressed mood, recent alcohol use, school mobility, family relationship quality, school engagement and coping style. Multinomial logistic regression analyses were used to identify school and family-related factors that distinguished those with co-occurring drinking and depressive symptoms from those with either single condition. Gender and school-level interactions for each factor were evaluated.Results: Co-occurring conditions were reported by 5.7% of students [confidence interval (CI)95 5.19, 6.19]. Recent drinkers were more likely than non-drinkers to have symptoms consistent with depression (odds ratio 1.80; CI95 1.58, 2.03). Low school commitment was associated with co-occurring drinking/depressive symptoms (odds ratio 2.86; CI95 2.25, 3.65 compared with null condition). This association appeared to be weaker in the presence of adaptive stress-coping skills (odds ratio 0.18; CI95 0.14, 0.23).Conclusions: We have identified factors that distinguish pre-teens with very early co-occurrence of drinking and depressed mood, and protective factors with potential utility for school-based prevention programmes targeting these conditions.

Aim The co-occurrence of mental health and substance use disorders adds complexity to already-significant health burdens. This study tests whether mental health disorders group differently across substance use disorder types and compares associations of early factors with the development of differing comorbidities. Design Consecutive antenatal clinic attendees were recruited to the longitudinal Mater-University of Queensland Study of Pregnancy (MUSP). Mother/offspring dyads were followed over 21 years. Setting Mater-Misericordiae Public Hospital, Brisbane, Australia. Participants MUSP offspring with maternal baseline information ( n = 7223), offspring behaviour data at 14 ( n = 4815) and psychiatric diagnoses at 21 ( n = 2575). Measurements The Composite International Diagnostic Interview yielded life-time diagnoses of mental health (MH) and substance use (SU) disorders for offspring, then latent class modelling predicted membership of polydisorder groups. We fitted the resulting estimates in multinomial logistic regression models, adjusting for maternal smoking, drinking and mental health, adolescent drinking, smoking and behaviour and mother-child closeness. Findings Fit indices [Bayesian information criterion (BIC) = 12 415; Akaike information criterion (AIC) = 12 234] from LCA supported a four-class solution: low disorder (73.6%), MH/low SU disorder (10.6%), alcohol/cannabis/low MH disorder (12.2%) and poly SU/moderate MH disorder (3.5%). Adolescent drinking predicted poly SU/MH disorders [odds ratio (OR) = 3.34, 95% confidence interval (CI) = 1.42-7.84], while externalizing predicted membership of both SU disorder groups (ORalcohol/cannabis = 2.04, 95% CI = 1.11-3.75; ORpolysubstance = 2.65, 95% CI = 1.1-6.08). Maternal smoking during pregnancy predicted MH (OR = 1.53, 95% CI = 1.06-2.23) and alcohol/cannabis-use disorders (OR = 1.73; 95% CI = 1.22-2.45). Low maternal warmth predicted mental health disorders only (OR = 2.21, 95% CI = 1.32-3.71). Conclusions Mental health disorders are more likely in young adults with polysubstance use disorders than those with alcohol/cannabis use disorders. Predictors of comorbid mental health/polysubstance use disorders differ from those for alcohol/cannabis use disorders, and are detectable during adolescence. [ABSTRACT FROM AUTHOR]

Background Substance and mental health disorders convey significant health burdens and impair interpersonal relationships. We tested associations between comorbid substance and mental health disorders and different forms of intimate partner violence (IPV) experienced by young adults. Method Mothers ( n = 6703) were recruited during pregnancy to the longitudinal Mater-University of Queensland Study of Pregnancy. Mother/offspring dyads were followed up from birth to 21 years. Offspring with complete psychiatric data at 21 years who reported having had an intimate partnership were included ( n = 1781). Participants’ experiences of psychological, physical and severe combined IPV were assessed at 21 years using a summarised form of the Composite Abuse Scale. We used the Composite International Diagnostic Interview to obtain lifetime diagnoses of mental health and substance disorders. Multivariable logistic regression models of each IPV form were adjusted for individual, family and neighbourhood factors during adolescence, and for other forms of IPV. Results We have shown specific links between different forms of IPV experienced and individual substance and mental health disorders. Mental health disorders were related to all three forms of IPV, while alcohol disorders were linked to psychological IPV (OR AUD = 1.86; 1.21–2.86) and illicit substance disorders to physical IPV (OR SUD = 2.07; 1.25–3.43). The co-occurrence of related disorders was strongly linked to psychological and physical IPV. Conclusions Intimate partner violence was experienced by both men and women. Substance and mental health disorders were associated with specific forms of IPV victimisation, suggesting that screening IPV clients and mental health/substance disorder patients for the converse problems may be important for intervention planning.

A letter to the editor is presented is response to an article on the community-based prevention programs for reducing alcohol consumption among adolescents, that was published in the previous issue of the journal.

Objective: Early onset of alcohol use is associated with an increased risk of substance use disorders (SUD), but few studies have examined associations with other psychiatric disorders. Our aim was to study the association between the age of first alcohol intoxication (AFI) and the risk of psychiatric disorders in a Finnish general population sample.Methods: We utilized a prospective, general population-based study, the Northern Finland Birth Cohort 1986. In all, 6,290 15-16-year old adolescents answered questions on AFI and were followed up until the age of 33 years for psychiatric disorders (any psychiatric disorder, psychosis, SUD, mood disorders and anxiety disorders) by using nationwide register linkage data. Cox-regression analysis with Hazard Ratios (HR, with 95% confidence intervals (CI)) was used to assess the risk of psychiatric disorders associated with AFI.Results: Statistically significant associations were observed between AFI and any psychiatric disorder, psychosis, SUDs, and mood disorders. After adjustments for other substance use, family structure, sex and parental psychiatric disorders, AFIs of 13-14 years and ≤12 years were associated with SUD (HR = 5.30; 95%CI 2.38-11.82 and HR = 6.49; 95%CI 2.51-16.80, respectively), while AFI ≤ 12 years was associated with any psychiatric disorder (HR = 1.59; 95%CI 1.26-2.02) and mood disorders (HR = 1.81; 95%CI 1.22-2.68). After further adjustments for Youth Self Report total scores, AFI ≤ 14 was associated with an increased risk of SUD and AFI ≤ 12 with an increased risk of any psychiatric disorder.Conclusions: We found significant associations between the early age of first alcohol intoxication, later SUD and any psychiatric disorder in a general population sample. This further supports the need for preventive efforts to postpone the first instances of adolescent alcohol intoxication. [ABSTRACT FROM AUTHOR]
