BACKGROUND Psychological well-being and health-specific self-regulation have been associated with cardiovascular health. This study aimed to examine the longitudinal relationship of positivity and health-specific self-regulatory variables to health-related quality of life in patients with cardiovascular disease. METHODS A sample of 550 cardiac patients completed a number of instruments (positivity, regulatory emotional self-efficacy, and cardiac self-efficacy scales, and the general health questionnaire SF-12) on two occasions 9 months apart, assessing their level of positivity, health-specific self-efficacy beliefs, and health-related quality of life. RESULTS Mediational analyses demonstrated that health-specific self-efficacy beliefs mediate the relationship between positivity and health-related quality of life. In terms of self-efficacy in managing negative affect, the despondency-distress factor showed both direct and indirect effects on health, while the anger factor showed only an indirect effect. The results of the structural equation model demonstrated suitable indices of fit. CONCLUSIONS Positivity may act as a disposition helps patients to use motivational strategies related to health, be more confident in their ability to regulate their emotions, and follow the recommendations of their cardiac medical team, enabling them to perceive a higher quality of life. These findings indicate the need to promote psychosocial interventions that include these variables.

解释心血管患者健康相关生活质量的积极性和自我效能信念。

背景心理健康和特定于健康的自我调节与心血管健康有关。本研究旨在检查积极性和特定于健康的自我调节变量与心血管疾病患者健康相关生活质量的纵向关系。方法 550 名心脏病患者样本在相隔 9 个月的两次时间内完成了多项工具（积极性、调节情绪自我效能感和心脏自我效能感量表，以及一般健康问卷 SF-12），评估他们的积极性水平，特定于健康的自我效能信念，以及与健康相关的生活质量。结果 中介分析表明，特定于健康的自我效能信念介导了积极性与健康相关生活质量之间的关系。在管理负面情绪的自我效能感方面，沮丧-困扰因素对健康有直接和间接影响，而愤怒因素只显示间接影响。结构方程模型的结果证明了合适的拟合指数。结论 积极性可以作为一种性格，帮助患者使用与健康相关的激励策略，对自己调节情绪的能力更有信心，并遵循心脏医疗团队的建议，使他们能够感知更高的生活质量。这些发现表明需要促进包括这些变量的社会心理干预。结构方程模型的结果证明了合适的拟合指数。结论 积极性可以作为一种性格，帮助患者使用与健康相关的激励策略，对自己调节情绪的能力更有信心，并遵循心脏医疗团队的建议，使他们能够感知更高的生活质量。这些发现表明需要促进包括这些变量的社会心理干预。结构方程模型的结果证明了合适的拟合指数。结论 积极性可以作为一种性格，帮助患者使用与健康相关的激励策略，对自己调节情绪的能力更有信心，并遵循心脏医疗团队的建议，使他们能够感知更高的生活质量。这些发现表明需要促进包括这些变量的社会心理干预。
