NCT05893550

Brief Summary

The overarching, long-term goals are to develop a non-invasive biological approach to prevention of youth aggression, and ultimately adult violence. The specific aims of this 2 x 2 randomized, double-blind, stratified, placebo-controlled trial of omega-3 supplementation to adolescents and caregivers are: (1) to investigate whether a nutritional intervention to adolescents and their parents can reduce externalizing behavior problems; (2) to examine the impact of a dual nutritional intervention to both parents and adolescents on adolescent externalizing behavior problems; (3) to identify mechanisms of action by which omega-3 supplementation impacts externalizing behavior in adolescents. It is expected that omega-3 supplementation will reduce adolescent behavior problems, and that dual supplementation to both the caregiver and adolescent will result in exponential improvements in adolescent behavior. A secondary prediction is that improvements in neurocognitive functioning will partially account for any behavioral improvements observed. Effects on scholastic ability are also explored.

Outcome Measures

Primary Outcomes (1)

  • Change in behavior problems

    Behavior problems are assessed on a battery of measures with standardized units from parent and child reports. . Aggressive behavior, rule-breaking behavior, and attention problems will be assessed using the Youth Self-Report (YSR; Achenbach \& Rescorla, 2001). The fourth scale is the 10-item version of the Inventory of Callous-Unemotional Traits (ICU; Ray et al., 2016). The final two scales are the Reactive and Proactive Aggression scales of the Reactive and Proactive Aggression Questionnaire (Raine et al. 2006). To reduce variables to a more reliable and all-encompassing construct of antisocial behavior, and to avoid Type 1 error, a principal components analysis was conducted on these six measures. Factor scores will be saved using the regression method, with higher scores indicating higher child antisocial behavior. Factor scores over time will be assessed.

Masking Details
The study is double-blind. Neither the participant nor the caregiver not the outcomes Assessor will know which group the participant is assigned to. The local PI in Mauritius (Tashneem Mahoomed, National Director) will also be blind to treatment condition. Only the PI in Philadelphia will have knowledge of treatment assignment, and he has no contact with participants in Mauritius.
