Abstract:
Posttraumatic growth (PTG) could emerge under the influence of traumatic events and treatments, which has a positive impact on the patients with acute coronary syndrome (ACS). However, low to moderate PTG was reported in ACS patients in China. This cross-sectional model testing design aimed to test a hypothesized model of PTG among ACS patients. Systematic sampling technique was used to recruit 396 ACS patients, who had been discharged for 1 to 6 months, from clinics in the tertiary care hospitals in Jiangsu Province, China. Research instruments included the Herth Hope Index, the Core Beliefs Inventory, the Patients Health Questionnaire Depression Scale, the Multidimensional Scale of Perceived Social Support, the Connor-Davidson Resilience Scale, the Event Related Rumination Inventory, and the Posttraumatic Growth Inventory. Their Cronbach alpha reliability ranged from .88 to .96. Descriptive statistics and Structural Equation Modeling were used to analyze the data. The results revealed that the modified model fit the data well. Challenges to core beliefs, depression, social support, deliberate rumination, and resilience explained 57% of the total variance for PTG in the modified model. Depression, deliberate rumination, and resilience had a direct effect on posttraumatic growth, whereas deliberate rumination and resilience were mediators between challenges to core beliefs, depression, social support, and posttraumatic growth. These findings suggest that development of an intervention to promote PTG among patients with ACS is important. The intervention should focus on improving challenges to core beliefs; promoting social support, deliberate rumination, and resilience; and preventing depression.
