Feasibility Study to Test the Implementation of Health Promotion Advice (Exercise and Protein Intake) for Older People Attending a Community Mental Health Service.

The goal of this observational study is to test the delivery of brief health promotion advice with supporting information leaflets as part of standard clinical consultation for older people attending a community mental health service The main questions it aims to answer are: 1. Is a brief health promotion intervention designed for primary care transferable and acceptable to older people attending acute community-based mental health services (Travers et al 2022) 2. Can older adults with ongoing mental health conditions be recruited and retained in the study 3. Will participants adhere to the health promotion intervention over a three-month period 4. Can evaluation data be collected from participants Eligible participants will be asked to: * participate in a brief health promotion (10 minutes) advice given by an advanced nurse practitioner (ANP) in mental health during a routine outpatient clinic/home visit * participants receive exercise and protein advice leaflets (laminated) * participants rehearse the exercise with the ANP * one-month follow-up by ANP to assess and promote adherence to the intervention Researchers will use a one-group pre-post test study to compare baseline data on physical and mental health outcomes to participants' outcomes at three-month follow-up (there is no control group).
