This study tested the efficacy of Coherence Therapy, compared with a self-help, bibliotherapy intervention, for people with procrastination and perfectionism problems. A total of 37 adults (65% male, 46% White, European American) were randomized to a Coherence Therapy intervention (n = 18) or a bibliotherapy condition (n = 19). Procrastination and perfectionism were assessed at pretreatment, posttreatment, and 6 months posttreatment. Analyses revealed that the Coherence Therapy group outperformed the bibliotherapy group in reducing maladaptive perfectionism but there were no substantial treatment effects on procrastination. Findings are discussed relevant to developing literature on Coherence Therapy and the treatment of perfectionism and procrastination.
