Testing the Factorial Validity and Measurement Invariance of College Student Scores on the Generalized Anxiety Disorder (GAD-7) Scale across Gender and Race

Responses to the Generalized Anxiety Disorder (GAD-7) scale displayed high score reliability ([alpha] = 0.91) and adequate convergent and divergent validity for college undergraduates. The data provided an adequate to excellent fit to the unidimensional model. Measurement invariance was demonstrated for gender and race.
