Effects of posttraumatic growth on psychosocial adjustment in young and middle-aged patients with acute myocardial infarction: The mediating role of rumination

Background: Psychosocial adjustment is a core problem faced by young and middle-aged patients following a diagnosis of acute myocardial infarction (AMI), which seriously affects rehabilitation outcomes. However, the relationship and influencing mechanism between post-traumatic growth and psychosocial adjustment in young and middle-aged AMI patients have not been fully explored. Objectives: This study aimed to determine the relationship between posttraumatic growth and psychosocial adjustment in young and middle-aged patients following AMI and to explore the mediating role of rumination. Methods: This cross-sectional study was conducted in Guangdong Province from January 2022 to August 2022. A total of 321 young to middle-aged patients with AMI participated in this study. Self-reported questionnaires were used to assess posttraumatic growth, rumination, and psychosocial adjustment. Pearson's correlation and path analyses were used to analyze the data. Results: The total scores for posttraumatic growth, rumination, and psychosocial adjustment in young and middle-aged patients with AMI were 51.24 +/- 19.35, 35.18 +/- 8.72, and 43.55 +/- 26.04, respectively. All three were considered moderate. Posttraumatic growth was positively associated with rumination and negatively associated with psychosocial adjustment (p < 0.01). The relationship between posttraumatic growth and psychosocial adjustment was mediated by deliberate rumination. Conclusions: Deliberate rumination mediated the relationship between posttraumatic growth and psychosocial adjustment. Healthcare providers should therefore guide patients to engage in deliberate rumination to help them grow following their AMI, thereby improving their psychosocial adaptability and prognosis.
