Use of individual differences questionnaire with psychiatric inpatients

Paivio's Individual Differences Questionnaire was given to 47 psychiatric inpatients. Their mean verbal and imagery scores were higher than those for Paivio and Harshman's 713 students. Also, the latter had higher verbal than imagery scores, while the psychiatric group had the opposite. Subjects with affective disorders had significantly higher mean scores on a subscale which measures vividness of dreams, day-dreams, and imagination than other diagnostic groups.
