[Non-completion of insurance-funded outpatient psychotherapy: frequency, risk factors, outcome].

OBJECTIVE: Because premature discontinuation of psychotherapy limits the effectiveness of the interventions, in a naturalistic design we examined the prevalence, predictors, and outcome of premature discontinuation.
METHODS: The sample included N = 584 patients with various mental disorders. Risk factors were identified using regression analysis. As outcome Patient Health Questionnaire scales were considered. We compared pre and post averages as well as post averages of premature discontinuation versus regular termination.
RESULTS: Risk factors were: female and/or unemployed patient, low patient and/or therapist ratings regarding therapy success, and extraordinarily high therapist ratings of the therapeutic alliance. Despite premature discontinuation we found significant reductions of depression, anxiety, somatic symptoms, and stress (ES = 0.30, …, 0.44). Compared to regular termination though, patients with premature discontinuation were more impaired at last measurement (ES = 0.17, …, 0.37).
CONCLUSION: Not each premature discontinuation is a psychotherapeutic failure. Warning signals for looming premature discontinuation are low ratings of therapy success while psychotherapeutic treatment. © Georg Thieme Verlag KG Stuttgart · New York.
