Childhood conduct problems (CP) are characterized by persistent behaviors that violate major societal norms and rules, as well as the rights of others (American Psychiatric Association, 2013). Critically, early emerging CP place children at heightened risk for the development of conduct disorder in adolescence and poor socioeconomic outcomes in adulthood, such as substandard occupational performance, substance abuse, and crime (Fergusson et al., 2005; Loeber & Hay, 1997). While effective treatments for CP have been established, these treatments are expensive and have barriers to access. Further, few preventative interventions for CP have been rigorously investigated. The proposed study examines the effectiveness of a social skills board game preventative intervention for CP that was tested through randomized controlled trial design in a sample of 5-to-6-year-old children (n=135). Compared to participants in the math board game condition and the no board game condition, participants in the social skills board game condition did not demonstrate greater reductions in CP. Unsurprisingly, callous-unemotional (CU) traits at baseline predicted CP at follow-up, in that those who had higher CU traits tended to also have higher CP. A lack of significant results may be attributed to the fact that this was a community sample rather than a clinical sample, the intervention period was too short, or the stress of the COVID-19 pandemic negated any potential effectiveness. Despite the social skills board game being ineffective for this sample at this time, the intervention still holds promise
