Psychological reactance and adolescent cannabis use: The role of parental warmth and monitoring.

Psychological reactance (PR) is a psychological state or trait typified by resistant responses to threats to behavioral freedom. PR has been linked with negative health behaviors, including risky substance use; however, factors that may foster approaches to mitigate the impact of PR on these behaviors, as well as rejection of other health promotion communications is less understood. The current studies examined relations between parental warmth and monitoring with trait PR and responses to preventive cannabis communications and usage intentions. Two in-school surveys were administered to two difference samples of middle school students (Study 1, N = 1,416; Study 2, N = 1,118). Path analytic models tested multivariable linkages among relevant parenting variables, PR, and outcomes associated with cannabis use. Follow-up regression analyses explored significant interaction effects. In Study 1 (p <0.001) and Study 2 (p <0.01), parental warmth moderated the relation between monitoring and trait PR: High monitoring was a protective factor only when combined with high warmth. In turn, PR mediated the relationships between parenting practices and cannabis intentions in both studies (p <0.001). In Study 2, PR also was linked with resistance to persuasion via more unfavorable reactions to anti-cannabis appeals (p <0.001). Findings indicated that low parental warmth combined with high parental monitoring was associated with high trait reactance in adolescents, which predisposed them to stronger resistance to preventive communications. Interventions might focus on counseling parents about the likely outcomes of parenting style, and ways to implement beneficial approaches.
