The present study aimed to evaluate the results obtained in the retirement preparation program (RPP) regarding changes in retirement planning behaviors, the meaning of work, and improvement in quality of life. It is a quasi-experimental research, using a pre-and post-test evaluation with a non-equivalent control group, including 82 participants, who were public workers near retirement. Among these, 50 participated in the RPP (experimental group (EG)) and 32 belonged to the control group (CG). All responded to the scale of changes in retirement planning behaviors, the Meaningful Work Scale, and the World Health Organization Quality of Life Assessment Instrument (WHOQOL-Brief), as well as a Sociodemographic and Occupational Data Questionnaire. The results showed that in the EG, there was an increase in the socio-occupational investment and in the coherence and expressiveness at work throughout the three periods considered, as well as in the quality of life related to the environment in the assessment conducted after the program. Regarding the comparison between the EG and the CG, differences were verified in the socio-occupational investment and in the social utility of work, and such characteristic was higher in the EG during the follow-up. The relevance of the present study lies in the improvement of intervention alternatives to support health policies, seeking to meet the demands of the aging population.
