The Washington University Sentence Complete Test: are the two halves alternate forms? Are the female and male forms...

Evidence from 85 adult medical outpatients supported psychometric comparability of the 2 halves of the Washington University Sentence Completion Test (SCT) Form 81 and of the female and male forms of the SCT. There was slightly stronger internal consistency for the first versus the second half of the SCT. Each half correlated highly with the ogive total protocol rating and 36-item-sum rating. Intercorrelations of the 2 halves with external measures also suggested essentially equivalent relations. For the 30 identical items across gender, the median correlation between individual item ratings with the item-sum ratings was nearly equal for women and men. When the 6 nonidentical items were considered with the identical items, the median item-total correlation was slightly higher for men (45) than women (41). This difference was accounted for by the slightly larger variability in the mate subsample. Practically speaking, the 2 halves and the female and male forms may be used with minimal concern regarding psychometric comparability in similar medical outpatient settings.
