Does a brief contact-based video intervention reduce public mental health stigma associated with psychosis in a collectivistic society? A randomised control study

Abstract

PurposeInternationally, among mental health difficulties, psychosis appears most stigmatised. Yet, research on mental health education specific to psychosis, including stigma reduction strategies, is limited. This study aims to evaluate the efficacy of a brief empirically informed indirect contact-based intervention (CBI) on reducing stigma associated with psychosis in the context of a Southeast Asian society.Design/methodology/approachIn total, 168 young adults were randomised into three groups, two intervention conditions and one active control. Stigmatisation levels were measured at pre-intervention, post-intervention and at a 30-day follow-up. Group differences in attitudes were analysed using a 3 × 3 two-way mixed-subjects ANOVA.FindingsResults revealed that there were no significant differences in declared stigma between the three conditions. However, a significant effect of time on the improvement of attitudes was observed at post-intervention. This effect was not sustained at follow-up.Social implicationsIndividual psychoeducational CBIs implemented in the context of collectivistic societies do not produce sustainable effects in the reduction of stigma. Although a transient desirable improvement in the attitudes occurs among individuals, this is subsequently counteracted by the influence of stigma existing on a systemic level. Therefore, public mental health education in collectivistic cultures should address societal mechanisms maintaining unhelpful perceptions of those with psychosis.Originality/valueThe study examined the effect of brief CBIs on the reduction of stigma associated with psychosis in a collectivistic society and demonstrated systemic limitations of individually delivered psychoeducational interventions.
