Conduct Disorder Symptoms and Illicit Drug Use in Juvenile Justice Involved Youth: The Reciprocal Relationship Between Positive Illicit Drug-Use Attitudes and Illicit Drug Use

Abstract

Conduct disorder (CD) symptoms cooccur at high rates with illicit drug use in juvenile justice involved youth, which results in poorer outcomes; however, research has not identified where best to intervene in this relationship, limiting the identification of modifiable risk factors to reduce negative effects of CD symptoms. Two mediation models were examined to investigate the potential for CD symptoms to influence a reciprocal relationship between illicit drug use and positive drug attitudes, controlling for age, gender, and race. Data were examined for 245 juvenile justice involved youth (mean age = 15.46, SD = 1.30, range 12-18, 64.9% Black, 80.4% male) who completed court-ordered psychological assessments. Findings indicate: (1) Positive attitudes toward illicit drug use significantly mediated the relationship between CD symptoms and illicit drug use (β = 0.16, CI 0.09-0.27; test for indirect effect z = 4.17, p < .001) and (2) illicit drug use significantly mediated the relationship between CD symptoms and positive attitudes toward illicit drug use (β = 0.20, CI 0.12-0.32; test for indirect effect z = 4.87, p < .001). Overall, the present study suggests that CD symptoms impart risk for illicit drug use both indirectly, through more positive attitudes toward illicit drug use, and directly, which further strengthens positive attitudes toward illicit drug use.

Results of mediation models run using Andrew Hayes process macro (Hayes, 2013), controlling for age, gender, and race. Top: Results indicated that the indirect effect of CD symptoms on illicit drug use through positive attitudes toward illicit drug use was significant (β = 0.16, CI 0.09 to 0.27; Test for indirect effect z = 4.17, p <.001). Bottom: Results indicated that the indirect effect of CD symptoms on positive attitudes toward illicit drug use through illicit drug use was significant (β = 0.20, CI 0.12 to 0.32; Test for indirect effect z = 4.87, p <.001).
