RESUMO
OBJECTIVE: This study examined the prevalence and correlates of generalized anxiety disorder (GAD) among primary care outpatients. METHOD: A multicenter, cross-sectional study was conducted that included 707 primary care outpatients being seen at 20 primary healthcare centers in Tunis and Sfax, Tunisia. The Mini International Neuropsychiatric Interview was used to identify a diagnosis of GAD. The Beck Depression Inventory was used to assess depressive symptom severity, and the Sheehan Disability Scale (SDS) was used to measure functional impairment. RESULTS: The prevalence of GAD was 11%. GAD was positively correlated with female gender (P = .005), family history of psychiatric disorder (P < .001), personal history of suicide attempt (P = .019), and depressive symptoms (P < .001). Based on the SDS, severe to very severe functional limitations were reported at work, in social life, and family life (56.4%, 60.2%, and 73.1%, respectively) among GAD patients. CONCLUSION: This study indicated a relatively high prevalence of GAD among primary care patients in Tunisia. Risk factors were also determined that may help to identify these patients. This information may help primary care physicians recognize this diagnosis and provide timely referrals to mental health professionals to prevent complications and preserve quality of life.
