Today,we have learnt the review about psychological interventions for major depression in primary care. Various studies have tested psychological therapies in the treatment of depression in primary care. Yet, concerns over their clinical effectiveness, as compared to usual general practitioner (GP) care or treatment with antidepressants, have been raised. This review was aimed at assessing currently available evidence on the topic. The method which they used is meta-analysis.The meta-analysis is a quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc., with application chiefly in the areas of research and medicine.

       In this review,a systematic search of electronic databases identified 10 randomized controlled trials comparing psychological forms of intervention with either usual GP care or antidepressant medication for major depression. Meta-analytical procedures were used to examine the impact of psychological intervention in primary care on depression, as compared to usual GP care and antidepressant treatment.At last, the main analyses showed greater effectiveness of psychological intervention over usual GP care in both the short term and long term. The heterogeneity test was not significant in the short term at the Pb.05 level, but it was significant in the long term. The comparison between psychological forms of intervention and antidepressant medication yielded no effectiveness differences, for either the short term or the long term.Psychological forms of intervention are significantly linked to clinical improvement in depressive symptomatology and may be useful for supplementing usual GP care.
