Research output: Contribution to journalArticlepeer-review


Although the Willoughby Personality Schedule appears to be widely used to assess interpersonal anxiety, there are few studies of its clinical validity or psychometric properties. The purpose of this study was to investigate the factor analytic structure of the Willoughby Schedule in an inpatient psychiatric population. It also explored the relationship of the Willoughby Personality Schedule to the Beck Depression Inventory (BDI), the Gambrill-Richey Assertion Inventory and patient perception of treatment outcome. In contrast to three Willoubhby Schedule factors previously reported in research with outpatients, six factors were found in this study. These were moderately correlated with scores on the BDI and the Assertion Inventory discomfort scale. Two Willoughby factors were related to the Assertion Inventory probability of assertive response scale and only one Willoughby factor was related to patient perception of treatment outcome. The overall results raise questions as to the usefulness of the Willoughby Schedule with inpatient populations.
