Examination of the indirect effect of alcohol expectancies on ethnic identity and adolescent drinking outcomes

Although overall rates of alcohol use tend to be lower among racial/ethnic minority youth compared to White youth, consequences associated with use tend to be more severe. Identifying factors that prevent alcohol use is crucial to reducing its impact among minority adolescents. One such factor is ethnic identity, which involves gaining clarity about one's ethnic background and regard toward one's ethnic group. Strong ethnic identity has been found to work through antidrug beliefs to decrease minority youth's substance use. The current study extends previous literature by examining whether specific alcohol cognitions-alcohol expectancies-explain the promotive effect of ethnic identity on alcohol use and severity of alcohol use among minority youth. Participants were 113 ethnic minority youth ages 12-18 (M = 15.27). Most participants were male (66%) and identified as non-Hispanic African American/Black (70%), followed by Hispanic/Latino (15%), multiracial (12%), and American Indian/Native American (3%). Participants completed self-report measures of ethnic identity, positive and negative alcohol expectancies, and hazardous drinking, which were analyzed in an indirect effects model. Results indicated that ethnic identity was inversely related to negative alcohol expectancies. A significant indirect effect of ethnic identity on severity of alcohol use through negative alcohol expectancies was found. However, no indirect effect was found for positive alcohol expectancies. Findings suggest that strong ethnic identity serves as a promotive factor preventing alcohol use for ethnic minority youth, in part through more negative alcohol expectancies, and may be a beneficial target for intervention programs to reduce alcohol use among this group.

Substance use disorder and posttraumatic stress disorder symptomology on behavioral outcomes among juvenile justice youth

BACKGROUND AND OBJECTIVES

Substance use behaviors have been identified as a risk factor that places juveniles at greater risk for engaging in delinquent behaviors and continual contact with the juvenile justice system. Currently, there is lack of research that explores comorbid factors associated with substance use, such as post-traumatic stress disorder (PTSD) symptoms, that could help identify youth who are at greatest risk. The aim of the present study was to examine if PTSD symptomology moderated the relationship between substance use disorder (SUD) symptoms and externalizing behaviors and commission of a violent crime; hypothesizing that risk would be heightened among youth with elevated SUD and PTSD symptomology compared to those with elevated SUD symptoms but lower PTSD symptoms.

METHOD

The study included 194 predominantly male (78.4%), non-White (74.2%) juvenile justice youth between the ages of 9-18 (M = 15.36). Youth provided responses to assess PTSD symptoms, SUD symptoms, and externalizing behaviors. Commission of a violent crime was based on parole officer report.

RESULTS

Findings indicated that SUD symptomology was associated with greater externalizing behaviors at high levels of PTSD symptomology. At low levels of PTSD symptomology, SUD symptoms were inversely associated with externalizing behaviors. An interactive relationship was not observed for commission of violent crimes.

CONCLUSIONS

Findings suggest that the association between SUD symptoms and externalizing behaviors among juvenile offenders may be best explained by the presence of PTSD symptomology.

SCIENTIFIC SIGNIFICANCE

Addressing PTSD rather than SUD symptoms may be a better target for reducing risk for externalizing behaviors among this population of youth (Am J Addict 2019;28:29-35).
