Method: We examined the reciprocal relationships among positive future expectations, expected threats to future safety, depression, and individual substance use and delinquency using four waves of data (N= 248-338) from African American and Latino adolescent male participants in the Chicago Youth Development Study (CYDS). CYDS is a longitudinal prospective cohort study of risk of school failure, antisocial behavior and violence among inner-city African American (53.7%) and Latino (42.7%) young men. 62% of participants live in single-parent homes, 47.6% of the families report income below $10,000/year, and 73.5% below $20,000. Participants were recruited from 17 Chicago public schools. Individual positive future expectations and expected threats to safety were assessed at each wave and modeled as latent constructs. Individual substance use and delinquency were assessed at each wave and represented as ordinal variables ranging from low to high. Categorical autoregressive cross-lagged structural models were used to examine the hypothesized reciprocal relationships between both aspects of future expectations and risk behavior across adolescence.
Results: Analyses show future expectations has important significant effects on youth substance use and involvement in delinquency, both of which in turn decrease positive expectations and increase expectation of threats to future safety across adolescence. Similarly, low positive expectations for the future continued to predict increased substance use and involvement in delinquency. Expected threats to safety was significantly correlated with delinquency within time. These effects are observed across adolescence after accounting for depression over time.
Conclusions: Findings support the reciprocal effects hypothesis of a negative reinforcing cycle in the relationships between future expectations and both substance use and involvement in delinquent behavior across adolescence. The enduring nature of these relationships underscores the importance of future expectation as a potential change mechanism for intervention and prevention efforts to promote healthy development–vulnerable racial and ethnic minority adolescent males may especially benefit from such intervention.
