Primary use / Purpose:
Background:
Worry is regarded as a dominant feature of GAD. Since its development in 1990, the PSWQ has become a widely used self-report tool for pathological worry and GAD. The PSWQ attempts to measure the excessiveness, generality, and uncontrollable dimensions of worry.
Psychometrics:
The PSWQ has shown to possess high internal consistency and good test-retest reliability (Meyer et al., 1990).
