OBJECTIVES: The Worry and Anxiety Questionnaire (WAQ) was initially developed to provide a rapid and efficient assessment of all the symptoms and diagnostic criteria for generalized anxiety disorder (GAD). Given that few instruments have been validated for evaluating GAD in older adults, the WAQ-being brief and assessing each component of GAD separately-may offer a valuable measure for this population. The present study examines its psychometric properties in older adults.
METHOD: A total of 495 participants aged 60-90 years took part in the study. The sample included 141 individuals diagnosed with clinical or subclinical GAD through a clinician-administered structured interview and 354 individuals from the general population. All participants completed the WAQ and additional assessment instruments.
RESULTS: A two-factor structure with good fit indices was identified for the WAQ. It demonstrated excellent internal consistency (ω = 0.96) and good convergent validity with other measures of GAD and related symptoms (r = 0.82). It also showed excellent sensitivity (95.8%) and adequate specificity (76.1%) for identifying probable GAD.
CONCLUSION: These results support the robust psychometric properties of the WAQ in older adults. Beyond assessing the severity of GAD symptoms, the WAQ represents a valuable tool to facilitate diagnosis in this population.
