Long-Term RCT outcomes for adolescent alcohol and cannabis use within a predominantly Hispanic sample

Because adolescents are unlikely to seek, receive, or complete treatment for alcohol and/or cannabis misuse, it is important to enhance the lasting impact of clinical contacts when they do occur. Adolescents (N = 506; 72.5% Hispanic) were randomized to motivational interviewing (MI) versus alcohol and cannabis education (ACE). Latent growth models estimated change over time. Significant reductions in alcohol use were observed, with slightly greater reductions by 12-month follow-up for MI. Both interventions significantly reduced cannabis use, with no treatment group differences. When outcomes were examined comparing Hispanic to non-Hispanic participants, there were no significant differences in intervention efficacy by group. MI's inherently client-centered and culturally adaptive approach may contribute to its equitable degree of behavior change for youth across race/ethnic backgrounds.     

Using video observation in the family context: The association between camera-related behaviors and parental sensitivity

Research on parental sensitivity often relies on video observation of parent–infant dyads. However, to date, no study has assessed both infants’ and parents’ interactions with the camera, and how this relates to parental sensitivity levels. This exploratory study micro-coded camera-related behaviors (CRB) by 4-month olds and their mothers and fathers on a 1-s time base, and examined the associations between those behaviors and parental sensitivity in 75 Dutch families. While parents’ CRB made up only 0.8% of total interaction time, infants’ made up 12%. Multi-level time-series analyses showed that infants’ CRB predicted mothers’. Infants’ CRB predicted fathers’ CRB, and vice versa. Maternal sensitivity was significantly lower when children looked at the camera for over one-third of total interaction time (Cohen's d = 1.26). These findings indicate further research is required to better understand how video observation might threaten ecological validity.
