Relationship Between Substance Use, Bullying, and Other Delinquent Behaviors Among High School Students: a Secondary Analysis of the Florida Youth Substance Abuse Survey

A longitudinal study of protective factors against substance use in early adolescence. An ecological approach

BACKGROUND

Adolescent substance use has been widely related to different individual, school, family and community factors. Yet, the number of studies with all these variables together in a model from an ecological perspective is still low, and they rarely used a longitudinal design. The aim of this study was to explore, from an ecological perspective, the prospective impact of different individual, school, family and neighbourhood factors on adolescent substance use.

METHODS

This was a longitudinal study with a one-year follow up. There were 881 participants (M_age = 12.57; 48.1% females) at wave 1, of which 686 (M_age = 13.51; 51.8% females) were followed-up at wave 2. Validated questionnaires were used for data collection.

RESULTS

Regression analyses showed that higher substance use was predicted by high family socio-economic status cross-sectionally and longitudinally, and it was related to low neighbourhood socio-economic status cross-sectionally only. Participants who disliked school and had a poor academic performance were more likely to use substances, both cross-sectionally and longitudinally.

CONCLUSIONS

The inclusion of families in substance use prevention programmes could be a key component in these interventions. Moreover, promotion of a positive school climate could protect adolescents from using substances.

Mutual Influences on Bullying Perpetration and Substance Use Among Adolescents in the United States

PURPOSE

Identifying temporal pattern of associations between bullying perpetration and substance use among youth is useful for optimal targeting of intervention and prevention. We examined the mutual influences on bullying perpetration and substance use and test the cumulative effects of bullying perpetration and substance use over time.

METHODS

We used data from the Population Assessment of Tobacco and Health cohort study, a nationally representative sample of youth, on bullying perpetration and substance use at three points in time over 3 years. We analyzed the associations of bullying perpetration with alcohol, cannabis and cigarette use using binary logistic regressions. The 13,068 youths aged 12-17 years at baseline (2013-2014) were included in the analytical sample.

RESULTS

Cross-sectional associations between bullying perpetration and substance use were found at baseline (odds ratio [OR]_alcohol = 1.62, 95% confidence interval [CI] 1.33-1.97; OR_marijuana = 1.28, 95% CI .99-1.66; OR_cigarette = 1.86, 95% CI 1.44-2.39). Cumulative episodic and frequent bullying perpetration over three data waves predicted an increased likelihood of substance use at follow-up (ORs between 1.18, 95% CI 1.02-1.36 and 2.13, 95% CI 1.66-2.74). Conversely, both episodic and frequent substance use predicted an increased probability of bullying others at follow-up (ORs between 1.50, 95% CI 1.20-1.86, and 2.10, 95% CI 1.69-2.61).

CONCLUSIONS

Associations between bullying perpetration and substance use appears to be bidirectional. In addition, episodic bullying perpetrators displayed intermediate levels of risk, suggesting a graded association between bullying perpetration pattern and substance use.
