Long-term psychotherapy in tertiary care: A practice-based benchmarking study

Abstract Objectives: The literature regarding the effectiveness of long-term psychological interventions delivered in tertiary care is scarce. This study sought to quantify and evaluate outcomes delivered in a UK tertiary care psychotherapy service against equivalent service benchmarks. Design: A retrospective analysis of outcomes on the Outcome Questionnaire-45 (OQ-45) over a 10-year period in a tertiary care psychotherapy service. The modalities evaluated were cognitive-behavioural, cognitive-analytic and psychoanalytic psychotherapies.
