Abstract
The Community Mental Health Team effectiveness questionnaire (CMHTEQ) is a 27-item measure of Community Mental Health Team (CMHT) effectiveness for completion by team members. It was constructed following a stakeholder conference representing the following constituencies: clinicians, users and carers, mental health researchers, policy makers and managers. We present a psychometric analysis of the CMHTEQ, based on the responses of 1450 (response rate: 75%)CMHT staff of a sample of 113 CMHTs recruited from all Trusts providing community mental health care across four English NHS Regions. Three factors emerged from an exploratory analysis of 50% of the data, upheld by a confirmatory analysis of the remaining data: meeting external requirements; internal team processes; evidence and feedback. Factor scales exhibited acceptable internal reliabilities. The CMHTEQ meets the need for a measure of the effectiveness of CMHTs, as perceived by their members, for use in research studies of the environment and effectiveness of mental health care, and by service managers or CMHTs seeking to monitor or track performance change over time.
