Content of the questionnaire
| Target audience | Adults |
|---|---|
| Application | The Penn State Worry Questionnaire – Past Week (PSWQ-PW) is primarily used in the outcome and trajectory measurement of pathological worry in treatments of patients with generalized anxiety disorders. |
| Composition | The 15 items of the PSWQ-PW are answered on 7-point Likert scales ranging from “0 = never” to “6 = almost always”. |
Psychometric properties
| Reliability & Validity | The psychometric properties of the PSWQ-PW have been investigated in Stöber & Bittencourt (1998). Very good values have been found. For example the internal consistency as measured by Cronbach’s Alpha was on average 0.91 across six measurement points. |
