This study examined the relationship between self-care adherence, time perspective (TP), readiness to change (RTC) and executive function in heart failure (HF) self-care. 147 heart failure patients completed questionnaires on self-care, TP, RTC; and cognitive tasks that reflect working memory and inhibition. Positive correlation was found between self-care, future-oriented TP (r = 0.362, P = 0.01), RTC (r = 0.184, P = 0.05) and working memory (r = 0.174, P = 0.01). Mediation analysis elucidated the indirect effect of RTC on self-care through TP (B = 1.205, bias-corrected bootstrapped at 95% confidence interval 0.532, 2.145) explaining 62.0% of the total effect. Working memory did not moderate this relationship and inhibition did not predict self-care. Self-care scores were lower than cut-off of 70 (mean = 51.2, standard deviation = 17.2). Age (r = − 0.220), staying alone (r = − 0.270) income < 1000 (r = − 0.270) and not having formal education (r = − 0.165) were correlated with TP. Healthcare professionals could motivate HF patients to perform regular self-care behaviours by tailoring interventions according to their TP and RTC.

心力衰竭患者自我护理依从性，时间观点，改变准备情况和执行功能之间的关系。

这项研究检查了自我护理依从性，时间透视（TP），改变准备情况（RTC）和执行功能在心力衰竭（HF）自我护理之间的关系。147名心力衰竭患者完成了关于自我护理，TP，RTC的问卷调查；以及反映工作记忆和抑制力的认知任务。在自我护理，面向未来的TP（r  = 0.362，P  = 0.01），RTC（r  = 0.184，P  = 0.05）和工作记忆（r = 0.174，P ）之间发现正相关= 0.01）。中介分析阐明了RTC通过TP对自我护理的间接影响（B = 1.205，偏差校正自举在95％置信区间0.532，2.145），解释了总影响的62.0％。工作记忆不能缓解这种关系，抑制作用不能预测自我护理。自我护理得分低于临界值70（平均值= 51.2，标准差= 17.2）。年龄（r  = − 0.220），独居（r  = − 0.270）收入<1000 （r  = − 0.270）和未接受正规教育（r  = − 0.165）与TP相关。医疗保健专业人员可以根据他们的TP和RTC量身定制干预措施，从而激发HF患者定期进行自我保健行为。
