Brief summary
1.To demonstrate the feasibility of conducting a RCT using omega-3 supplementation with a community sample of impulsive, repeat-violent offenders. Secondary objectives 1.To collect information about the effectiveness of omega-3 supplementation on 3-month behavioural measures of impulsivity, anger, depression and irritability in impulsive, repeat-violent offenders. 2.To collect information about the effectiveness of omega-3 supplementation in reducing self-reported offending among impulsive, repeat-violent offenders.
Interventions
This pilot study will utilise a double-blind, randomised, placebo-controlled trial of omega-3 supplementation in 50 men who have been convicted of violent crimes in NSW. Upon entry into the study, participants will be randomised into either the treatment (n=25) or placebo (n=25) arm of the study. Treatment Participants enrolled in the study will take 5 x 1gm capsules orally per day for three months. Those receiving the active treatment will receive 5 x 1g fish oil capsules, containing a total of 3000mg LC-omega-3 FA (2000mg EPA, 1000mg DHA) taken once daily for 3 months. Adherence will be assessed using both direct questioning by the research assistant, pill counting, and erythrocyte omega-3 content based on blood omega-3 levels. Participants will be required to return empty medication packs at the follow-up assessments (6 and 12 weeks) and asked to provide a blood sample at baseline and 12 weeks for measurement of omega-3 content in erythrocyte membrane phospholipids. Participants will also be asked during the follow-up phone calls how many days they have missed taking their capsules. Participants will also be asked to return the capsules at each face-to-face meeting with the research assistant, the remaining number of capsules will then be counted.
