The changes that retirees experience during their retirement years will challenge their ability to cope, potentially endangering their health and quality of life. This study aims to design and evaluate a theory-based health promotion programme to improve retirees’ psychological well-being and quality of life.

This mixed-method, non-blinded study uses an embedded design. The purposive sampling method will be employed for the qualitative aspect of the study. Qualitative data will be collected at baseline, focusing on retirement adjustment, through semistructured, in-depth individual interviews and focus group discussions. The data will be analysed using Graneheim and Lundman’s qualitative content analysis method. A pre–post test controlled group design will be conducted for the quantitative part of the study. A sample size of 80 is estimated for both the intervention and control groups. Systematic sampling and the block randomisation method will be employed for sampling. The training programme in the intervention group will consist of eight 60 min sessions and environmental support, implemented after assessing the research environment and obtaining approval from the relevant officials. A brief training programme unrelated to the intervention group’s focus (home safety) will be implemented for the control group. Quantitative measures will be collected in both groups at baseline, 3 months and 6 months after the intervention. These measures will include self-administered questionnaires covering demographic variables, retirement adjustment, retirement resources, quality of life, coping methods, spiritual well-being and psychological well-being. Analytical statistics will be performed using the generalised linear model, with p values≤0.05 considered significant.

This protocol has received approval from the ethics committee of Shiraz University of Medical Sciences. The research findings will be disseminated through peer-reviewed manuscripts, presentation in abstracts at National and International Scientific Conferences, and data sharing among researchers.
