Abstract
Thirty-seven community-dwelling, older generalized anxiety disorder (GAD) patients and 37 nonanxious controls completed the Generalized Anxiety Disorder Questionnaire for DSM-IV (GAD-Q-IV; Newman et al., 2002), the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, 2004), and other measures of anxiety and depression. The GAD-Q-IV and DERS were assessed for internal consistency reliability, construct validity, and test–retest reliability, with results indicating good psychometric performance. Receiver operating characteristic (ROC) analysis conducted on the full sample suggested that the optimal GAD-Q-IV cutoff for classifying GAD cases was 3.71, with .97 sensitivity and .92 specificity. The cutoff score for classifying those participants with GAD and comorbid conditions was higher, however. ROC analysis with the full sample revealed an optimal DERS cutoff score of 62.5, with .76 sensitivity and .86 specificity. Findings support the use of the GAD-Q-IV and DERS as screening instruments for GAD in older, community-dwelling adults in a research setting.
