The article by Bolier et al. presents a Meta analytical study to show the efficacy of positive psychology as an intervention. The use of positive psychological interventions has for some time been applied as a complementary strategy in the enhancement of treatment of mental health problems. The article presents a study of the use of the strategy among individuals and the general public with particular mental health problems as recorded in different articles

Different variables were seen to moderate the effect on depression. The results showed that the impact of Interventions was more effective when participants were exposed to them for a longer period.  However, the quality of the studies varied a great deal, and there was some suggestion of publication bias that was found.  The results of the study confirmed that positive psychology interventions can be successful in the improvement of subjective psychological well-being, as well as in reducing depression.

Many studies provide evidence for positive psychology techniques mainly conducted with healthy participants and with patients experiencing emotional problems including anxiety and depression as their main complaint. The authors of this study take a different approach by carrying a Meta-analysis study to show the effectiveness of positive psychology interventions. The researchers carried out a systematic literature search using PsychInfo, PubMed, Cochrane Register besides to manual searches.  40 articles that met the criteria were selected for inclusion.  The authors used different measures of outcome including psychological well-being, depression, and subjective well-being. The positive psychology interventions used in the study included group training, self-help interventions and individual therapy.

The Results of the study showed a standardized mean difference of 0.20 for psychological well-being, 0.34 for subjective well-being and 0.23 for depression. The results at first showed a small effect for positive psychology interventions.  A follow-up carried out between the three to six months indicated a significant small effect in sizes.  The researchers noted a high level of Heterogeneity because of the wide diversity of the studies used. Geared toward counseling practitioners, the article presents why, how, and under what conditions different interventions are successful, and for whom.  The results of this study indicated that a positive psychology intervention have significant beneficial effects for patients. Even though it should not to be anticipated that positive psychology intervention on its own is entirely sufficient to treat patients, the findings propose that it may be a valuable complement to enhance the effectiveness of other interventions.
