Personality and coping styles in the prediction of dropout from treatment for cocaine abuse

This study was designed to distinguish between dropouts and completers of residential therapeutic community treatment for cocaine abuse on the basis of the Millon Clinical Multiaxial Inventory II (MCMI-II; Millon, 1987) and Ways of Coping Checklist (WCCL; Folkman, Lazarus, Dunkel-Schetter, DeLongis, & Gruen, 1986) scales, which measure detached, dependent, and independent personality and coping styles. Dropouts were differentiated from completers in two discriminant functions defined, in part, by scores on scales that tap a fiercely independent orientation with manipulative, exploitive, and confrontive interpersonal features. Also contributing to the discriminant functions identified in this study were scores on scales that measure responsiveness to direction from others associated with strong desire for social approval and ability to establish self-control of emotional and behavioral reactions.
