Psychometric Properties of the Nine‐Item Personal Health Questionnaire (PHQ‐9) Seven‐Item Generalised Anxiety Disorder Scale (GAD‐7), and the Work and Social Adjustment Scale (WSAS) With People With Intellectual Disabilities
In this study, the widely used PHQ-9, GAD-7 and WSAS demonstrate internal consistency values and factor analysis structure similar to those for individuals without intellectual disabilities. The data support the use of these measures for people with intellectual disabilities attending routine primary care mental health services.
