A TEST BATTERY ASSESSING SPECIFIC AND GENERAL TREATMENT EFFECTS WAS READMINISTERED TO SS PREVIOUSLY ASSESSED BEFORE TREATMENT, AFTER TREATMENT, AND AT A 6-WK FOLLOW-UP FROM GROUPS UNDERGOING INDIVIDUAL PROGRAMS OF (1) MODIFIED SYSTEMATIC DESENSITIZATION, (2) INSIGHT-ORIENTED PSYCHOTHERAPY, (3) ATTENTION-PLACEBO TREATMENT, AND (4) NO TREATMENT. HIGHER RETURN RATES WERE OBTAINED THAN IN ANY PREVIOUS LONG-TERM FOLLOW-UP, REVEALING MAINTAINANCE OF IMPROVEMENT FOUND EARLIER FOR INTERPERSONAL PERFORMANCE ANXIETY. SYSTEMATIC DESENSITIZATION RESULTED IN THE GREATEST SIGNIFICANT IMPROVEMENT (85%), FOLLOWED BY INSIGHT-ORIENTED PSYCHOTHERAPY AND ATTENTION PLACEBO (50% EACH), AND UNTREATED CONTROLS (22%). CHANGES WERE RELIABLE, PREDICTABLE, AND SHOWED EVIDENCE OF FURTHER GENERALIZATION. NO EVIDENCE OF RELAPSE OR SYMPTOM SUBSTITUTION WAS OBTAINED, ALTHOUGH THEY WERE SPECIFICALLY SOUGHT. METHODOLOGICAL PROBLEMS OF FOLLOW-UP STUDIES ARE ALSO DISCUSSED. (36 REF.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
