Studies employing the Mooney Problem Check List (MPCL) have found that counseling center clients indicate more problems on the MPCL than nonclients. Domino and DeGroote identified 42 MPCL items concerned with self-satisfaction and a need for social contacts which further differentiated counseling seekers from nonseekers. In order to further validate the 42-item MPCL as a predictive instrument, three studies were undertaken. In Study 1, 40 students (24 male,16 female) were administered the MPCL upon entering the university. During the course of their college careers, 20 students were seen in counseling; the other 20 students served as controls. Student responses to the MPCL were classified according to the 42 identified items. An analysis of the results showed the classification system correctly identified all controls but only 2 of the 20 counseling seekers. However, the items did significantly differentiate the two groups. In Study 2, 74 students (37 counseling seekers and 37 controls) were administered the MPCL, and their responses were classified according to the 42 items. An analysis of the results, as in Study 1, showed that the items differentiated the two groups, but failed to predict counseling seekers from nonseekers. In Study 3, scores from the second study were recalculated to improve the predictive accuracy of the 42-item MPCL. Cutoff points of 11 and 5 for counseling seekers were set. An analysis of the results showed that the cutoff point of 5 was significant in classifying counseled from noncounseled students. The studies validated the usefulness of the 42-item MPCL in predicting who will seek counseling. However, separate norms should be developed at each university. (BL)
