Objective: ADHD in adolescents and low level of parental monitoring have been associated with increased risk-taking behavior. The present study examined whether parental knowledge of the child’s whereabouts mediates the correlations between adolescent ADHD symptoms and risk-taking behavior. Method: Ninety-two adolescents and their parents completed questionnaires assessing perceptions of parents’ monitoring, engagement in risk-taking behaviors, and ADHD symptoms. Results: Greater engagement in risk-taking behavior correlated with higher levels of ADHD symptoms and decreased parental monitoring. Mediation analysis revealed both direct effect of ADHD symptoms on risk-taking behavior and an indirect effect mediated by level of parental knowledge. Conclusion: These findings suggest that parental knowledge is negatively affected by the presence of ADHD symptoms, and may in turn lead to risk-taking behavior. The findings emphasize the need to target parenting and in particular parental knowledge of the child’s whereabouts to reduce risk-taking behaviors among youth with ADHD.

Compared to childhood and adulthood, adolescence is a time of greater risk-taking behavior, potentially resulting in serious consequences. Theories of adolescent brain development highlight the imbalance between neural circuitry for reward vs. regulation. Although this imbalance may make adolescents more vulnerable to impaired decision-making in the context of heightened arousal, not all adolescents exhibit problematic risk behavior, suggesting other factors are involved. Relatedly, parent-adolescent conflict increases in mid-adolescence, and is linked to negative outcomes like substance use related risk-taking. However, the mechanism by which parent-adolescent conflict and risk-taking are linked is still unknown. Therefore, we investigated this association using a multi-method experimental design. Parent-adolescent dyads were randomly assigned to complete a discussion task together on the topic of either the adolescent’s dream vacation or an adolescent-identified conflict topic. During the task, adolescent peripheral psychophysiology was measured for later calculation of heart rate variability (HRV), an index of self-regulation. Immediately after the discussion task, adolescents completed a performance-based measure of risk-taking propensity that indexes real-world risk behaviors. We hypothesized that parent-adolescent conflict would predict greater adolescent risk-taking propensity, and that increased behavioral arousal in the context of conflict, coupled with impaired self-regulation, would explain this link. Results indicated no direct effect of parent-adolescent conflict on adolescent risk-taking propensity. However, there was a significant conditional indirect effect: lower HRV, indexing worse regulatory ability, mediated the relation between conflict and risk-taking propensity but only for adolescents exhibiting behavioral arousal during the discussion task. We discuss implications for understanding adolescent risk-taking behavior.

This study aims to investigate the relationship between the managerial risk-taking, managerial competencies and financial service outreach of microfinance banks in Pakistan. Primary data was collected from 36 branches of microfinance banks (MFBs) in nine cities. The unit of investigation is the branch manager and senior credit officer of each MFB branch. Descriptive statistics, correlation and regression, are used for data analysis. This study found a positive relationship between financial service outreach of MFBs and managerial competencies; financial service outreach also has a positive relationship with the risk-taking behavior of managers. There is a positive relationship between risk-taking behavior and financial service outreach of banks. The risk-taking behavior partially mediates the relationship between the managerial competencies and financial service outreach. The magnitude of the relationship between managerial competencies and outreach is significant, and its magnitude reduces when there is the mediation of managerial risk-taking behavior between them. Thus, managerial competencies, along with risk-taking behavior are the keys drivers of financial service outreach of MFBs. This study informs MFB’s top management and policymakers that competencies of managers and their calculated risk-taking propensities determined outreach performance of the MFBs.
