Cost and clinical effectiveness of mindfulness-based cognitive therapy for the prevention of depressive relapse in a primary mental health service: a pre–post and follow-up study

Depression is a highly common condition (World Health Organisation, 2022). Although many people demonstrate recovery there are marked levels of relapse. Mindfulness-based cognitive therapy (MBCT) is effective in preventing relapse. To date, the majority of studies do not primarily focus on the cost-effectiveness of MBCT within health care utilisation and workplace absenteeism. This study aims to explore the effectiveness of MBCT for prevention of depression relapse in patients attending a UK NHS primary care service. An observational (pre–post and follow-up) study of patients (n=23) who experienced at least three depressive episodes were provided with MBCT. Cost-effectiveness was assessed using self-report measures of service utilisation and employment absence. These were assessed before MBCT, following, and 6 months post. Secondary outcomes assessing clinical effectiveness included measures of depression (PHQ-9), anxiety (GAD-7), and functional impairment (WSAS). There was a significant reduction in absenteeism at work and in health care usage and expenditure at the end of treatment. These improvements were continued during the follow-up period. Secondary outcomes indicated clinical improvements on depression, anxiety and functioning were maintained to follow-up.
