Measurement invariance of the PHQ-9 and GAD-7 across males and females seeking treatment for common mental health disorders.

ABSTRACT:

Background

The nine-item Patient Health Questionnaire (PHQ-9) and the seven-item Generalised Anxiety Disorder scale (GAD-7) scales are routinely used in research and clinical practice. Whilst measurement invariance of these measures across gender has been demonstrated individually in general population studies and clinical samples, less is known about invariance of the distinct but correlated latent factors ('depression' and 'anxiety'). The current study assessed measurement invariance of these constructs across males and females seeking treatment for common mental health disorders.

Methods

Data were provided from eight psychological treatment services in London, England. Data from initial assessments with the services where individual items on the PHQ-9 and GAD-7 were avail
