Abstract:In this meta-analysis it is examined what the mean effect is of interventions aimed at improving psychological well-being as conceptualized by Ryff and measured by ‘Ryff’s psychological well-being scale’ (Ryff’s PWBS). The four databases Pubmed, Psycinfo, The Cochrane Library and Embase were searched for studies in which the effect of an intervention was measured by Ryff’s PWBS or the ‘mental health continuum – short form’ (MHC-SF) and in which the research design was a randomized controlled trial. Analysis of the data showed the mean effect size Cohen’s d = 0.47, which implies a medium effect of the interventions on psychological well-being. Psychological well-being is part of the complete measure of positive mental health which also includes emotional and social well-being. In this article it is argued that it is important that outcome measures of intervention research cover both mental illness and positive mental health. When this is the case, as the two-continua model of mental health implies, a more complete image of mental health can be formed.
