Mediating role of physical activity in the relationship between psychological distress and intimate relationships among stroke patients.

BACKGROUND

Stroke patients often experience psychological distress, which can impact their intimate relationships with spouses, subsequently influencing their treatment and recovery. Physical activity is considered a key rehabilitation method for stroke patients. This paper aims to analyze whether psychological distress affects intimate relationship between spouses through physical activity.

AIM

To explore the mediating effect of physical activity between psychological distress and intimate relationship in stroke patients.

METHODS

A total of 256 stroke patients who underwent treatment at the First People's Hospital of Shangqiu between July 2021 and July 2022 were enrolled in this study. The participants completed questionnaires, including the Kessler Psychological Distress Scale (K10), the Quality of Relationship Index (QRI), International Physical Activity Questionnaire, and a general information questionnaire. Data analysis were performed using SPSS 23.0. The Harman test was employed to detect common method deviations, and Spearman correlation was used for correlation analysis. The mediating effect was assessed using Process 3.4.1, with significance testing of the regression coefficients conducted using the bias-corrected percentile Bootstrap method (5000 iterations, 95% confidence interval). Statistical significance was set at < 0.05.

RESULTS

The results showed that patients scored an average of 21.61 ± 6.44 points on the K10, 32.40 ± 6.19 points on the QRI; the median physical activity level according to the International Physical Activity Questionnaire was 1861 (566, 2846) MET·min/w. The level of physical activity (the physical activity intensity of the patients reflected by the International Physical Activity Questionnaire-Long Form scale) negatively correlated with psychological distress and intimacy ( < 0.05), and positively correlated with each other ( < 0.05), with the correlation stronger at lower physical activity levels compared to higher ones. The mediating effect of physical activity between psychological distress and intimate relationship was calculated to be 40.23%. Bootstrap analysis further validated the results. The mediating effect of psychological distress on intimate relationships through physical activity level was -0.284, with a confidence interval of -0.409 to -0.163, excluding 0, confirming a significant mediating effect of psychological distress on intimate relationships.

CONCLUSION

Physical activity significantly affects relationship between psychological distress and intimate relationships among stroke patients. Addressing the role of physical activity may have implications for improving patient outcomes and rehabilitation strategies.
