This is a 36-week, randomised, double-blind, placebo-controlled trial. The overarching aim of this study is to assess whether a nutritional intervention (Omega-3 supplement), when combined with a more traditional treatment approach to conduct disorder and Attention Deficit Hyperactivity Disorder (ADHD), is more effective than either approach alone in treating these conditions in children and adolescents. The research questions cannot be answered through alternative means because disruptive behaviour disorders are primarily childhood disorders.

Serious adult crime and violence is a social problem despite decades of intervention and prevention work. One of the reasons for the world-wide failure to prevent this problem stems from (a) a failure to tackle the biological component of the crime/ violence equation in treatment programs, and (b) the failure to tackle this adult condition in its formative childhood origins. Investing modest resources in early biosocial prevention programs could yield enormous long-term financial dividends in terms of the saved legal, medical, social, and psychological costs resulting from adult crime. This initial study would be the first to test the efficacy of conjoint Omega-3 plus social skills training, and the first to identify possible mechanisms by which Omega-3 reduces antisocial behaviour. A) Initial evidence for effects of Omega-3 supplementation on conduct disorder and Attention Deficit Hyperactivity Disorder (ADHD) B) Moderators of the hypothesised relationship between omega-3 supplementation and conduct disorder C) Social skills training as a treatment for conduct disorder D) The combined effectiveness of omega-3 and social skills training E) Mechanisms of action underlying any treatment effect The total daily dosages will be 400 mg of DHA and 600 mg of EPA, typical of prior intervention studies of children in the age-range in the proposed study (e.g. Itomura et al. 2005; Richardson & Puri, 2002). The study involves children and adolescents diagnosed with disruptive behaviour disorder (DBD, i.e. conduct disorder or oppositional defiant disorder) or attention deficit / hyperactivity disorder (ADHD, i.e. combined type or ADHD predominantly inattentive type or ADHD predominantly hyperactive-impulsive type). The overarching aim of this study is to assess whether a nutritional intervention (Omega-3 supplement), when combined with a more traditional treatment approach to conduct disorder and ADHD, is more effective than either approach alone in treating these conditions in children and adolescents. The research questions cannot be answered through alternative means because disruptive behaviour disorders are primarily childhood disorders. Violence is a world-wide public health problem that has largely defied successful intervention and prevention. The overarching aim of this study is to assess whether a nutritional intervention, when combined with social skills training, is more effective than either approach alone in reducing childhood conduct disorder, the precursor to adult crime and violence. The specific aims are: Subjects will consist of 600 male and female children seeking treatment at the Child Guidance Clinic. Subjects given a primary diagnosis by the attending physician of either a disruptive behaviour disorder (DBD, i.e. conduct disorder or oppositional defiant disorder) or attention deficit / hyperactivity disorder (ADHD, i.e. combined type or ADHD predominantly inattentive type or ADHD predominantly hyperactive-impulsive type) will be included. This a randomised, double-blind, placebo-controlled trial with 4 x 3 x 4 x 2 (4 treatments groups x 3 diagnostic groups x 4 time measurements of an outcome variable x 2 genders) between-subject design to evaluate whether Omega-3 supplement, when combined with social skills training, is more effective than either approach alone in reducing childhood conduct disorder and attention deficit hyperactivity disorder.
