RESUMO
Treatment-related decreases in Dysfunctional Attitudes Scale (DAS; Weissman & Beck, 1978) scores have been interpreted as evidence that dysfunctional attitudes are state-dependent concomitants of depression. Data from the National Institute of Mental Health Treatment of Depression Collaborative Research Program were used to reexamine the stability of dysfunctional attitudes. Mean scores for Perfectionism, Need for Approval, and total DAS decreased after 16 weeks of treatment. However, test-retest correlations showed that the DAS variables displayed considerable relative stability. Structural equation models demonstrated that dysfunctional attitudes after treatment were significantly predicted by initial level of dysfunctional attitudes as well as by posttreatment depression. The relative stability of dysfunctional attitudes was even higher during the 18-month follow-up period. The results were consistent with Beck's (1967) and Blatt's (1974) theories of vulnerability.

Perfectionism has previously been identified as having a significant negative impact on therapeutic outcome at termination in the brief (16-week) treatment of depression (S. J. Blatt, D. M. Quinlan, P. A. Pilkonis, & T. Shea, 1995) as measured by the 5 primary outcome measures used in the National Institute of Mental Health Treatment of Depression Collaborative Research Program (TDCRP). The present analyses of other data from the TDCRP indicated that this impact of perfectionism on therapeutic outcome was also found in ratings by therapists, independent clinical evaluators, and the patients and that this effect persisted 18 months after termination. In addition, analyses of comprehensive, independent assessments made during the treatment process indicated that perfectionism began to impede therapeutic gain in approximately 2/3 of the sample, in the latter half of treatment, between the 9th and 12th sessions. Implications of these findings are discussed, including the possibility that more perfectionistic patients may be negatively impacted by anticipation of an arbitrary, externally imposed termination date.
