Effectiveness of routine psychotherapy: Method matters

摘要

Objective: Though many studies have shown that psychotherapy can be effective, psychotherapy available in routine practice may not be adequate. Several methods have been proposed to evaluate routine psychological treatments. The aim of this paper is to demonstrate the combined utility of complementary methods, change-based benchmarking, and end-state normative comparisons, across a range of self-reported psychological symptoms. Method: Benchmarks derived from randomized controlled trials (RCTs) and normative comparisons were used to evaluate the effectiveness of psychotherapy in a large (N = 9895) sample of clients in university counseling centers (UCCs). Results: Overall, routine psychotherapy was associated with significant improvement across all symptoms examined. For clients whose initial severity was similar to RCT participants, the observed pre-post effect sizes were equivalent to those in RCTs. However, treatment tended to lead to normative end-state functioning only for those clients who were moderately, but not severely, distressed at the start of psychotherapy. Conclusions: This suggests that although psychotherapy is associated with an effective magnitude of symptom improvement in routine practice, additional services for highly distressed individuals may be necessary. The methods described here comprise a comprehensive analysis of the quality of routine care, and we recommend using both methods in concert.
