Abstract

Purpose: This study aimed to evaluate the effects of a laughter therapy program on successful aging, heart rate variability (HRV), and SOC-based coping strategies in middle-aged women. Research design, data and methodology: A quasi-experimental, non-equivalent control group design was used. The study targeted middle-aged women and applied a 6-week laughter therapy program. Data were collected using pulse wave–based HRV measurements (SDNN, LF/HF ratio, HRV-Index, TP, HF, LF) and questionnaires assessing SOC coping strategies and successful aging. Data were analyzed to compare pre- and post-intervention changes between groups. Results: The experimental group showed significant improvements in successful aging, SOC coping strategies, and selected HRV indices (SDNN, LF/HF ratio, HRV-Index). However, no significant differences were found in TP, HF, and LF between groups. Conclusions: The laughter therapy program was effective in enhancing physiological regulation, coping strategies, and successful aging in middle-aged women. It suggests potential as a practical community-based health promotion intervention, although further research with rigorous design and long-term follow-up is needed.
