Abstract
BACKGROUND
Addressing the wider determinants of mental health alongside psychological therapy could improve mental health service outcomes and population mental health.
OBJECTIVES
To estimate the effectiveness of an enhanced 'Improving Access to Psychological Therapies' (IAPT) mental health service compared with traditional IAPT in England. Alongside traditional therapy treatment, the enhanced service included well-being support and community service links.
DESIGN
A real-world evaluation using IAPT's electronic health records.
SETTING
Three National Health Service IAPT services in England.
PARTICIPANTS
Data from 17 642 service users classified as having a case of depression and/or anxiety at baseline.
INTERVENTION
We compared the enhanced IAPT service (intervention) to an IAPT service in a different region providing traditional treatment only (geographical control), and the IAPT service with traditional treatment before additional support was introduced (historical control).
PRIMARY OUTCOME MEASURES
Patient Health Questionnaire-9 (PHQ-9) Depression Scale (score range: 0-27) and Generalised Anxiety Disorder-7 (GAD-7) Anxiety Scale (score range: 0-21); for both, lower scores indicate better mental health. Propensity scores were used to estimate inverse probability of treatment weights, subsequently used in mixed effects regression models.
RESULTS
Small improvements (mean, 95% CI) were observed for PHQ-9 (depression) (-0.21 to -0.32 to -0.09) and GAD-7 (anxiety) (-0.23 to -0.34 to -0.13) scores in the intervention group compared with the historical control. There was little evidence of statistically significant differences between intervention control and geographical control.
CONCLUSIONS
Embedding additional health and well-being (H&W) support into standard IAPT services may lead to improved mental health outcomes. However, the lack of improved outcomes compared with the geographical control may instead reflect a more general improvement to the intervention IAPT service. It is not clear from our findings whether an IAPT service with additional H&W support is clinically superior to traditional IAPT models.
