A comparative study on the effects of Mitchell and Benson relaxation techniques on quality of life of the old people in nursing homes: a quasi- experimental study

BACKGROUND: There is slight evidence on the effectiveness of relaxation techniques to improve quality of life of the old people, and no comparative studies have particularly investigated this population. Hence, the present study was conducted to examine the effect of Mitchell relaxation versus Benson relaxation technique to improve quality of life of the old people. METHODS: In the present quasi-experimental study, 96 eligible old people in a nursing home were selected by available sampling method. Afterwards, they were assigned to three groups: Mitchell’s Relaxation Technique, Benson Relaxation Technique, and control (each of 32 participants) using the random block sampling method. The intervention groups received relaxation for 8 weeks and 3 sessions of 20 min each week. However, the control group did not receive any relaxation. Data was gathered by questionnaires (SF-36) and (CASP-19) before (week 0) and after the intervention (week 8) and were analyzed using the SPSS software version 26. RESULTS: The results indicated that both Benson and Mitchell relaxation had improved the quality of life (SF-36) and (CASP-19) and their sub-scales in the participants compare to the control group (P < 0.001). Accordingly, the median (quartile 25, 75) of the specific quality of life of the participants before the intervention was 21 (18.25, 25.75) in the Benson group, 20.5 (16, 24) in the Michel group, and 21 (16.25, 24) in the control group. However, after the intervention they reached 35(26.25, 38.75), 34.5(26.75, 42.25), and 17 (14, 21) respectively. There was no statistically significant difference between the Benson and Michel relaxation groups. CONCLUSIONS: Based on the results, Benson and Mitchell relaxation techniques improve the quality of life of the old people. If the results be confirmed in other studies, the education of each of them, especially for the old people living in nursing homes and their caregivers, is suggested as routine care.
