Identifying anxiety and depressive disorders among primary care patients: a pilot study.

One stage case-identification method, using the Arabic Version of the Hospital Anxiety and Depression Scale (HAD) was applied in a pilot study for estimating the prevalence of depressive and anxiety disorders among a group of Saudi primary care attenders. The validity of the Arabic Version of the HAD scale was previously tested and found valid with high sensitivity and specificity. The total prevalence rate of depression was 17% and that of anxiety was 16%. Seven percent of the sample suffered both depression and anxiety i.e. the total percentage of patients with depression, anxiety or both was 26%. Higher morbidity of depression was recorded among females and a higher morbidity of anxiety among male patients.
