Content of the questionnaire
Target audienceAdults
ApplicationThe 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.
CompositionThe 15 items of the PSWQ-PW are answered on 7-point Likert scales ranging from “0 = never” to “6 = almost always”.
Psychometric properties
Reliability & ValidityThe 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.
