Brief summary

Aggressive behaviours are common issues in young people accessing mental health services. Fish oils are popular treatments and are sometimes marketed for behavioural problems. However, no research has specifically examined fish oils for aggressive behaviour in young people. This study will examine whether fish oil is able to reduce the frequency and severity of aggressive behaviour in children and adolescents.

Interventions

Fish oil oral capsules - 4 grams fish oil daily, containing a total of 400mg Eicosapentaenoic Acid (EPA) and 2000mg Docosahexaenoic Acid (DHA), for 6 weeks continuous treatment
