Abstract
Based on the widely used Penn State Worry Questionnaire for trait worry, a scale was developed to measure the level of worry
experienced during the past 24 h. This instrument, the Penn State Worry Questionnaire—Past Day (PSWQ-PD), was administered
to a student sample and two clinical samples. The PSWQ-PD demonstrated high internal consistency, good convergent validity
and adequate test-retest reliability. A confirmatory factor analysis revealed that a unifactorial solution provided the best
fit. Moreover, it was shown that the PSWQ-PD is a more state-like worry measure than the original PSWQ. The PSWQ-PD is a promising,
brief tool for daily worry assessment, which is apt for frequent administration.
