Summary
Substance use and violence often co-occur in adolescents, increasing mortality risks. Protective factors like social support can reduce the likelihood of engaging in these harmful behaviors.
Area of Science:
- Adolescent Health
- Public Health
- Behavioral Science
Background:
- Substance use (SU) and violence are major contributors to adolescent mortality.
- Identifying shared protective factors is critical for prevention strategies.
- Understanding typologies of SU and violence can inform targeted interventions.
Purpose of the Study:
- To characterize adolescent substance use and violence typologies.
- To examine the associations between protective factors and these typologies.
Main Methods:
- Cross-sectional surveys from 17 high schools involving 3,641 adolescents.
- Assessment of individual, interpersonal, and environmental protective factors.
- Latent class analysis to identify risk profiles and multinomial regression to assess associations.
Main Results:
- Five distinct adolescent groupings emerged based on SU and violence levels.
- High rates of fighting, marijuana use, and vaping were observed.
- High social support was linked to lower odds of membership in higher-risk categories, while future orientation was associated with reduced odds of sexual violence and SU.
Conclusions:
- Adolescent substance use frequently co-occurs with multiple forms of violence.
- Interventions should address compounding exposures in at-risk youth.
- Protective factors like social support and future orientation play a significant role in mitigating these risks.

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
