The role of drunken older siblings and drunken peers in the alcohol-violence nexus

"I Am Becoming More and More Like My Eldest Brother!": The Relationship Between Older Siblings, Adolescent Gambling Severity, and the Attenuating Role of Parents in a Large-Scale Nationally Representative Survey Study

The present study examined the association between having older siblings who gamble and adolescent at-risk/problem gambling and how parents (i.e., parental knowledge of their whereabouts) and peers might moderate such effects. Data were drawn from the ESPAD^®Italia2012 survey (European School Survey Project on Alcohol and Other Drugs) comprising a nationally representative Italian sample of adolescents. The analysis was carried out on a subsample of 10,063 Italian students aged 15-19 years (average age = 17.10; 55 % girls) who had at least one older sibling and who had gambled at some point in their lives. Respondents' problem gambling severity, older gambler sibling, gambler peers, parental knowledge, and socio-demographic characteristics were individually assessed. Multinomial logistic regression analyses including two- and three-way interactions were conducted. The odds of being an at-risk/problem gambler were higher among high school students with older siblings that gambled and those with peers who gambled. Higher parental knowledge (of who the adolescent was with and where they were in their leisure time) was associated with lower rates of at-risk/problem gambling. There was also an interaction between gamblers with older siblings and parental knowledge. The combination of having siblings who gambled and a greater level of parental knowledge was associated with lower levels of problem gambling. The present study confirmed the occurrence of social risk processes (older siblings and peers who gambled) and demonstrated that gambling among older siblings and peers represents an important contextual factor for increased at-risk/problem gambling. However, parental knowledge appears to be sufficient to counterbalance the influence of older siblings.

Risk and Protective Factors for Trajectories of Violent Delinquency Among a Nationally Representative Sample of Early Adolescents

To estimate trajectories of violence using a longitudinal sample of adolescents, considering the effects of multiple domains of influences as differentiators between profiles of violent behavior. A nationally representative sample of 9,421 adolescents ages 15-26. Trajectories were estimated, and multinomial regression procedures were used to evaluate factors predicting membership in high-violence trajectory groups. Mediation analyses were conducted to evaluate the mediated effect of distal influences on violence. Three groups of violence trajectories were identified: (a) nonviolent (73.1%); (b) escalators (14.6%); and (c) desistors (12.3%). Peer alcohol use predicted both escalation and desistance; however, these effects were mediated through individual-level variables. Aside from baseline violence, no other risk factor predicted membership in the "escalator" group. The lack of significance in predicting escalation highlights the need for further study on the etiology of late onset violence. Implications for violence prevention are discussed.

Parent attitudes, family dynamics and adolescent drinking: qualitative study of the Australian Parenting Guidelines for Adolescent Alcohol Use

Background

Parents play a critical role in their children’s introduction to alcohol. A range of parenting factors have been associated with the progression to risky drinking among adolescents, and have recently formed the basis of the Australian ‘Parenting Guidelines for Adolescent Alcohol Use’ designed to help parents delay or reduce their adolescents’ alcohol use.

Methods

This study aimed to explore the experiences and attitudes of parents of adolescents to gain insight into: (1) the extent to which the behaviours of parents follow the recommendations made in the guidelines; and (2) approaches to reduce hazardous drinking among adolescents. Thirty-two telephone and face-to-face interviews were conducted with parents, and the content of discussions was examined using thematic analysis.

Results

Parents used approaches they thought would minimise harm and promote healthy development in their children. The guidelines address key areas of concern for parents but their adherence to these approaches is low in certain areas. Many parents provided some alcohol to their adolescents and often cited the social norm of drinking among their adolescents’ peers as a source of pressure to supply.

Conclusions

Further dissemination of the guidelines may be the first step in a public health strategy, but it is likely that parents will require support to effectively adopt the recommendations. Understanding the influences on parents’ beliefs about their children’s drinking and the functions of social networks in the creation of behavioural norms relating to alcohol consumption and supply may be necessary to address adolescent risky drinking.

Victimization and Violent Offending: An Assessment of the Victim-Offender Overlap Among Native American Adolescents and Young Adults

The purpose of this article is to evaluate the victim-offender overlap among a nationally representative sample of Native American adolescents and young adults. Data for this study were obtained from 338 Native American youth who participated in the National Longitudinal Study of Adolescent Health (Add Health) Waves I-IV. Group-based trajectory modeling was used to estimate trajectories of violence and victimization separately. Bivariate tests were used to assess the overlap between victimization and violent trajectory groups. Multinomial regression procedures were used to assess the predictors of victimization, offending, and the overlap category of both victimization and offending. Three trajectory groups were found for violence (nonviolent, escalators, and desistors) and victimization (nonvictim, decreasing victimization, and increasing victimization). We found substantial evidence of an overlap between victimization and offending among Native Americans, as 27.5% of the sample reported both victimization and offending. Those in the overlap group had greater number of risk factors present at baseline. These results suggest that the victim-offender overlap is present in Native American adolescents. Explanations and implications are discussed.

Early Adolescent and Peer Drinking Homogeneity: Similarities and Differences Among European and North American Countries

This study examined associations between perceived peer and adolescent alcohol use in European and North American countries. Self-reported monthly alcohol use and adolescents' report of their peers' alcohol use were assessed in nationally representative samples of students aged 11.5 and 13.5 years (n = 11,277) in Greece, Scotland, Switzerland, and the United States who participated in the 2005/2006 Health Behavior in School-Aged Children survey. Cross-national associations between perceived peer and adolescent alcohol use were examined using logistic regressions and interactions by gender and country. Perceived peer and adolescent alcohol use were positively associated in all countries, but the association was notably weaker in Greece than in Scotland (boys), and in Greece compared to Switzerland (girls). Further examination of the underlying processes that explain stronger and weaker associations between perceived peer and adolescent alcohol use in some settings could guide the development of effective, culture-specific interventions.

The Mediated Effect of Contextual Risk Factors on Trajectories of Violence: Results from a Nationally Representative, Longitudinal Sample of Hispanic Adolescents

The current study sought to estimate trajectories of violent behavior and evaluate the direct and indirect effects of contextual factors among Hispanics, stratified by gender. Relying on data from 3,719 Hispanic adolescents surveyed as a part of the National Longitudinal Study of Adolescent Health (Add Health), violence trajectories were estimated using group-based trajectory modeling. The results identified three groups of violence trajectories for both males and females (non-violent, desistors, and escalators) and there were considerable gender differences in the direct and indirect effects of risk and protective factors on violent behavior. Study limitations and policy implications are also discussed.
