The authors conducted an all-Wales survey of community mental health nurses (CMHNs) to determine their levels of stress, coping and burnout. A total of 301 CMHNs were surveyed in 10 NHS Trusts in Wales. A range of measures were used. These included the General Health Questionnaire (GHQ-12), Maslach Burnout Inventory (MBI), Rosenberg Self-Esteem Scale (SES), Community Psychiatric Nursing (CPN) Stress Questionnaire, and PsychNurse Methods of Coping Questionnaire. The findings from the Rosenberg SES are reported here. Community mental health nurses in Wales scored as having average self-esteem. When the data were divided into high and low self-esteem, a large group of CMHNs (40%) were found to have low self-esteem. Factors that are associated with low and high self-esteem were identified. Alcohol consumption and being on lower nursing grades (D, E, F) were associated with low self-esteem, whilst amount of experience working as a CMHN was associated with high self-esteem.
