How prevalent are mental disorders in developing countries?


A national epidemiologic survey was conducted in Morocco in 2003-2004 in order to assess the prevalence of mental disorders in a representative sample of the general population.

Methods and subjects

About 5,600 persons accepted to be interviewed. The instrument used was the M.I.N.I. in its colloquial Moroccan Arabic, which was validated in a previous study.


The point prevalence of mental disorders was as follows: depressive disorders: 26.5%; suicidal ideation: 16.6%; bipolar disorder: 3.2%; Panic disorder: 6.6%; Social phobia: 6.3%; OCD: 6.6%; PTSD: 2.1%; alcohol dependence: 1.4%; substance abuse: 3.0%; GAD: 9.3%.

All in all, about 48.9% of the sample showed one or another mental disorder. Comparisons will be shown with the same instruments in some European and some African countries.
