Familial expressed emotion among heroin addicts in methadone maintenance treatment: Does it matter?

Abstract

BackgroundExpressed emotion (EE) is the quality of the atmosphere between a relative and a family member with mental illness. Substantial research has focused on the relationship between the level of EE and the outcomes of mental illness. However, no prior study has explored the role of EE relative to heroin addicts. AimThe aims of this study were to investigate the influence of EE on patient outcome in methadone maintenance treatment (MMT) and the relationship between the EE of heroin addicts and other demographic and psychological variables. MethodsA total of 117 heroin addicts who entered MMT were enrolled. Each subject underwent a comprehensive interview to record demographic data and drug use history. The Family Emotional Involvement Scale (FEICS), Beck Depression Inventory (BDI), and Beck Anxiety Depression Inventory (BAI) were used at baseline. All subjects were followed for 12months. The results of monthly urine tests and the treatment retention were recorded for further analysis. ResultsPerceived criticism was correlated with depression (r=0.20, P<0.01). The overall retention rate in 12-month MMT was 54.70%. Lower perceived criticism (OR=1.84, 95% CI=1.20–3.60, P<0.01) and lower depression (OR=1.24, 95% CI=0.65–1.80, P=0.02) predicted longer retention in MMT. ConclusionEE, especially perceived criticism, has its influences on outcomes among heroin addicts in MMT. This suggested the potential benefits of family therapy among high EE heroin addicts in MMT. Furthermore, the mechanism how EE affects the outcome of MMT needs to be further investigated.
