| Abstract: | The MMPI protocols obtained upon admission to an inpatient program for treatment of polydrug abuse were studied to determine if they could identify abusers who terminated prematurely from treatment. Individual scale T scores, profile code types and discriminant scores were evaluated for 104 patients who completed treatment ("stayers") and 72 patients who left prematurely ("quitters"). Although quitters and stayers did not differentiate on primary drug of abuse, age, sex, race, or IQ, quitters were less likely to obtain normal limits or neurotic code profiles, Univariate analyses revealed that quitters obtained higher mean elevations on 6 of the 15 scales studied (F, 4/Pd, 6/Pa, 8/Sc, 9/Ma, A). Discriminant scores based on a stepwise discriminant analysis correctly identified 71% of the study sample, representing a 13.7% improvement over base rate prediction. The probable importance of initial level of psychological discomfort and ability to delay gratification, and the need to examine varied treatment modalities for polydrug abusers identified as at risk for premature termination from treatment were explored. |
