Perceived control has been suggested as a modifiable factor associated with health-related quality of life (HRQOL). However, the relationship between perceived control and HRQOL has not been evaluated in patients with heart failure (HF). The purpose of this study was to determine whether perceived control independently predicts HRQOL in HF patients.
A total of 423 HF patients were included. Hierarchical linear regression was performed to determine the independent association of perceived control to HRQOL after controlling for covariates.
Higher levels of perceived control were associated with better HRQOL in univariate analysis. However, this relationship was strongly attenuated after controlling for relevant demographic, clinical, and psychological factors; the variance in HRQOL explained by the addition of perceived control to this model was small (1.4%).
We found only a weak relationship between perceived control and HRQOL when considered in the presence of demographic, clinical, and psychological factors.
感知控制被认为是与健康相关生活质量（HRQOL）相关的一个可改变因素。然而，心力衰竭（HF）患者中感知控制与HRQOL之间的关系尚未得到评估。本研究的目的是确定感知控制是否能独立预测HF患者的HRQOL。
共纳入423例HF患者。在控制协变量后，进行分层线性回归以确定感知控制与HRQOL的独立关联。
在单变量分析中，较高水平的感知控制与较好的HRQOL相关。然而，在控制了相关的人口统计学、临床和心理因素后，这种关系显著减弱；在该模型中加入感知控制后，HRQOL的方差解释率很小（1.4%）。
当考虑人口统计学、临床和心理因素时，我们发现感知控制与HRQOL之间只有微弱的关系。
