Associations between youth homelessness, sexual offenses, sexual victimization, and sexual risk behaviors : A systematic literature review

Homeless youth commonly report engaging in sexual risk behaviors. These vulnerable young people also frequently report being sexually victimized. This systematic review collates, summarizes, and appraises published studies of youth investigating relationships between homelessness, perpetration of sexual offences, experience of sexual victimization, and engagement in sexual risk behavior. A systematic search of seventeen psychology, health, and social science electronic databases was conducted. Search terms included “homeless*”, “youth”, “offend*”, “victimization”, “crime”, “rape”, “victim*”, and “sex crimes”. Thirty-eight studies were identified that met the inclusion criteria. Findings showed homeless youth commonly report being raped and sexually assaulted, fear being sexually victimized, and engage in street prostitution and survival sex. Rates of victimization and sexual risk behavior were generally higher for females. Given the paucity of longitudinal studies and limitations of current studies it is unclear whether homelessness is prospectively associated with sexual victimization or engagement in sexual risk behavior, and whether such associations vary cross-nationally and as a function of time and place. Future prospective research examining the influence of the situational context of homelessness is necessary to develop a better understanding of how homelessness influences the perpetration of sexual offences, experience of sexual victimization, and engagement in sexual risk behavior among homeless youth

Alcohol warning labels: unlikely to affect alcohol‐related beliefs and behaviours in adolescents

Abstract Objective: In Australia, many health researchers and policy makers are advocating for mandated warning labels on alcoholic beverages. Alcohol‐related harms are of particular concern among adolescents. The aim of this article was to review the available literature and evaluate the impact of alcohol warning labels on adolescent drinking, knowledge and behaviour. Approach: A systematic review of the literature was conducted. Scholarly databases were searched for relevant research articles. Broad inclusion criteria were applied due to the relative paucity of literature. Conclusion: The introduction of alcohol warning labels was shown to be associated with initial increased awareness of alcohol warning label law, exposure to the labels, and increased recognition of the warning label messages. Conversely, little change was observed in terms of beliefs about the risks of alcohol use or participation in risky alcohol‐related behaviours. These findings are similar to those reported among adult samples. However, the vast majority of the literature originated from the same group of authors, with samples drawn from a single geographical region. This may greatly limit the generalisablity of these findings. Implications: The introduction of alcohol warning labels in Australia may increase awareness about the risks of alcohol consumption among adolescents; however, these labels appear unlikely to change adolescent drinking behaviours or beliefs about alcohol‐related risks. Further research in multiple cultural contexts is required to confirm these findings. Alcohol warning labels should be considered as only one aspect of a range of other proven strategies to change knowledge, attitudes and behaviour

Risk factors and risk-based protective factors for violent offending: A study of young Victorians

Purpose The present study aims to examine risk factors and risk-based and interactive protective factors for violent offending in a group of 437 young Australians. Methods Participants were recruited into the study when they were in Grade 5 (age 10–11 years) and followed up almost annually until young adulthood (age 18–19 years). Measures of violent offending, risk and protective factors, and demographics were obtained through a modification of the Communities That Care youth survey. The data collected enabled identification of groups of students at-risk of violent offending according to drug use, low family socioeconomic status, and antisocial behavior. Results Very few associations were found between the risk factors and risk-based protective factors measured in this study (e.g., belief in the moral order, religiosity, peer recognition for prosocial involvement, attachment to parents, low commitment to school, and poor academic performance) and later self-reported violent offending. There were no statistically significant interactive protective factors. Conclusions Further longitudinal analyses with large sample sizes are needed to examine risk factors and risk-based protective factors and interactive protective factors in at-risk groups. The findings support the need for multi-faceted prevention and early intervention approaches that target multiple aspects of youth's lives

'Fighting' for surviva : A systematic review of physically violent behavior perpetrated and experienced by homeless young people

Objectives: This systematic review appraises published studies reporting associations between homelessness, perpetration of physically violent behavior and experience of victimization due to others' physically violent behavior, among young people. Methods: A comprehensive systematic search of psychology, sociology, and health electronic databases, including PsycInfo and SocIndex was conducted. Search terms examined (a) homeless youth, (b) perpetration of physically violent behavior, and (c) experience of victimization due to others' physically violent behavior. Results: Twenty-nine studies met the inclusion criteria. Findings showed homeless youth report engaging in physically violent behavior including assault, physical fights, and robbery, and commonly describe victimization experiences such as being physically assaulted, threatened with weapons, and robbed. Rates of perpetration of physically violent behavior and experiences of victimization were inconsistent across reviewed studies. It is unclear whether homelessness is a predictor of the perpetration of physically violent behavior and/or victimization. Findings suggest that perpetration of, and being victimized by others' physically violent behavior, may vary for sub-groups of homeless youth. Conclusions: Further research embedded within theoretical perspectives that consider the influence of situational antecedents is warranted to examine whether homelessness is predictive of engagement in physically violent behavior and the experience of victimization due to others' physically violent behavior

Cannabis use and related harms in the transition to young adulthood: a longitudinal study of Australian secondary school students

The current study documents the changing rates of cannabis use, misuse and cannabis-related social harms among Australian adolescents as they grow into young adulthood. It utilised data from a longitudinal study of young people at ages 15, 16, 17, and 19. The rates of cannabis use were found to increase as participants aged; past year use increased from 7.5% at age 15 to 29.8% at age 19. Further, at ages 17 and 19, cannabis use was more prevalent among males than females. Among those who reported cannabis use, the rates of cannabis-related harms were low to moderate, and did not increase with age in the same manner as rates of cannabis use. The most prevalent self-reported cannabis-related harm was anxiety/depression; affecting between 20–30% of the cannabis users at each age. These findings may assist in understanding the extent of cannabis-related problems among youth, and in planning relevant services

A longitudinal study of the reciprocal effects of alcohol use and interpersonal violence among Australian young people

The impact of alcohol-related violence on individuals and society continues to receive attention from both media and policy makers. However, the longitudinal relationship between alcohol consumption and violence is unclear, with findings from prospective studies producing mixed results. The current study utilized Australian data from the International Youth Development Study to examine longitudinal relationships between alcohol consumption and severe interpersonal violence across the developmental periods of early adolescence to late adolescence/emerging adulthood. The full sample comprised 849 adolescents (53.8 % female) who had been followed up over a 5 year period, from Grade 7 secondary school (age 13) until Grade 11 secondary school (age 17). Cross-lagged path analysis was used to examine reciprocal relationships between alcohol consumption and interpersonal violence; analyses controlled for a range of covariates considered to be common risk factors for both behaviors. Alcohol use during early and mid adolescence was found to predict violence 2 years later, whereas a bi-directional relationship between adolescent heavy episodic drinking and violence was observed. Some of these relationships were not significant when covariates such as family conflict and affiliation with antisocial and drug using friends were included in the models. These findings suggest that risk processes begin in late childhood or very early adolescence; efforts to reduce one problem behavior are likely to reduce the other. Further, the role that social and family contexts have in influencing the relationships between alcohol use and interpersonal violence should be considered in future research to better inform preventive efforts

Problem gambling patterns among Australian young adults: associations with prospective risk and protective factors and adult adjustment outcomes

There is instability in the developmental course of problem gambling [PG] over time; however, studies that examine PG at an aggregate level obscure these variations. The current study employed data from a longitudinal study of Australian young adults to investigate: 1) PG patterns (i.e., resistance, persistence, desistence, and new incidence); 2) prospective risk and protective factors for these patterns; and 3) behavioural outcomes associated with these patterns. A sample of 2261 young adults (55.73% female) from Victoria, Australia, who were part of the International Youth Development Study completed a survey in 2010 (T1, age 21) and 2012 (T2, age 23) measuring PG (two items based on established measures), risk and protective factors, and behavioural outcomes. The majority of the sample (91.69%) were resistors (no PG at T1 and T2), 3.62% were new incidence PG cases, 2.63% were desistors (PG at T1 but not T2), and 2.07% reported persistent PG at T1 and T2. Individual civic activism was protective of new incidence PG, while affiliation with antisocial peers and frequent alcohol use increased the risk of persistence. Persistent problem gamblers also experienced the greatest number of poor behavioural outcomes at T2. New incidence was associated with internalising symptoms at T2, while desistance was not associated with any behavioural outcomes. In conclusion, each PG pattern was associated with different predictors and outcomes, highlighting the need to consider variation in the course of young adult PG in order to provide efficacious prevention and intervention approaches, and to protect against relapse

Relationships between sport participation, problem alcohol use, and violence: A longitudinal study of young adults in Australia

There is a growing body of evidence suggesting a link between sport participation and violent behavior outside of the sporting context. However, there have been few studies that have investigated the basis of this relationship. The current study examined longitudinal relationships between sport participation, problem alcohol use, and various violent behaviors, and whether sport participation moderates relationships between problem alcohol use and violence. The sample comprised 2,262 young adults (55% female, age range at Time 1 = 17-24 years) from Victoria, Australia, surveyed in 2010 and 2012. When controlling for common risk factors, substance use, and past violence, sport participation was not associated with any violent behaviors 2 years later. However, sport participation moderated the relationship between problem alcohol use and fighting, whereby problem alcohol use was associated with engaging in fights 2 years later for sport participants, but not for nonparticipants. These findings suggest that it is not sport participation per se that influences later violence but the drinking norms or culture embedded within certain sporting contexts. Prevention approaches that address the drinking culture and social approval of excessive alcohol consumption within sporting contexts may reduce the incidence of violent behavior in the community

Developmental trajectories of adolescent cannabis use and their relationship to young adult social and behavioural adjustment: a longitudinal study of Australian youth

This study aimed to identify distinct developmental trajectories (sub-groups of individuals who showed similar longitudinal patterns) of cannabis use among Australian adolescents, and to examine associations between trajectory group membership and measures of social and behavioural adjustment in young adulthood. Participants (n=852, 53% female) were part of the International Youth Development Study. Latent class growth analysis was used to identify distinct trajectories of cannabis use frequency from average ages 12 to 19, across 6 waves of data. Logistic regression analyses and analyses of covariance were used to examine relationships between trajectory group membership and young adult (average age: 21) adjustment, controlling for a range of covariates. Three trajectories were identified: abstainers (62%), early onset users (11%), and late onset occasional users (27%). The early onset users showed a higher frequency of antisocial behaviour, violence, cannabis use, cannabis-related harms, cigarette use, and alcohol harms, compared to the abstinent group in young adulthood. The late onset occasional users reported a higher frequency of cannabis use, cannabis-related harms, illicit drug use, and alcohol harms, compared to the abstinent group in young adulthood. There were no differences between the trajectory groups on measures of employment, school completion, post-secondary education, income, depression/anxiety, or alcohol use problems. In conclusion, early onset of cannabis use, even at relatively low frequency during adolescence, is associated with poorer adjustment in young adulthood. Prevention and intervention efforts to delay or prevent uptake of cannabis use should be particularly focussed on early adolescence prior to age 12
