Summary of "Factorial invariance of a computerized version of the GAD-7 across various demographic groups and over time in primary care patients."

The Generalized Anxiety Disorder 7-item scale (GAD-7) is commonly used by clinicians and researchers to screen for anxiety disorders and to monitor anxiety symptoms in primary care. However, findings regarding its factor structure are mixed, with most studies reporting a best-fitting for a one-factor structure, whereas others indicate a two-factor model. To be valid for comparisons, the GAD-7 should measure the same latent construct with the same structure across groups and over time. We aimed to examine the best-fit factor structure model of the GAD-7 among primary care patients and to evaluate its measurement invariance.

Demographic and epidemiologic changes that have occurred in the last five decades in many developing countries and that are characterized by major growth in the number and proportion of middle-aged and elderly persons and in the frequency of the diseases that occur in these age groups. The health transition is the result of efforts to improve maternal and child health via primary care and outreach services and such efforts have been responsible for a decrease in the birth rate; reduced maternal mortality; improved preventive services; reduced infant mortality, and the increased life expectancy that defines the transition. (From Ann Intern Med 1992 Mar 15;116(6):499-504)
