Abstract
OBJECTIVE: To translate and validate Generalized Anxiety Disorder -7scale in Urdu, for use in Pakistan in the primary healthcare setups. METHODS: The validation study was conducted at the Combined Military Hospital, Gilgit, Pakistan, from February to May 2016.We followed a systematic six-step process to validate the Generalized Anxiety Disorder-7 scale in the target population. The instrument was translated independently and then fused together. Back-translation was followed by recommendations by an expert committee, and face validity improvement by a language expert. A pilot study was done to get user's feedback on the construct. Volunteers were administered the questionnaire for validation procedure, along with a well-being scale, at three different cities representing volunteers from four different administrative regions of Pakistan. RESULTS: There were 285 volunteers in the study. Principal component exploratory factor analysis supported unidimensional structure of the scale with an eigenvalue of 5.18 and it explained 64.8% of the total variance. Total score on the scale was negatively correlated with positive effect (r = -0.44, p<0.001) and life satisfaction (r = -0.49, p<0.001) subscales of a the well-being scale, while it was positively correlated with the negative affect (r = 0.63, p<0.001) subscale of the same, indicating a good level of convergent and discriminate validity. Cronbach's alpha for the scale was 0.92 and split-half reliability was 0.82, revealing a good level of reliability. CONCLUSIONS: The Generalized Anxiety Disorder -7 scale was found to be a validated, brief, self-administered Urdu tool to screen, rate, and monitor outcome of anxiety disorders in primary healthcare setups.
