Perceived control is strongly associated with health-related quality of life (HRQOL) among patients with chronic conditions, and it is possible to increase perceived control with appropriate intervention. Little is known about the relationship between perceived control and HRQOL in implantable cardioverter defibrillator (ICD) recipients.
To determine the relationship of perceived control with quality of life in ICD recipients and to determine predictors of perceived control in this population.
A total of 263 ICD recipients (63% male, age 61 ± 14 years) completed the Control Attitude Scale-Revised to measure perceived control and completed self-reported measures on potential correlates of perceived control (i.e., depressive symptoms, anxiety, social support, and ICD concerns). The EuroQol-5D was used to measure HRQOL. Regression analysis was used to determine predictors of perceived control and its relationship to HRQOL, controlling for covariates.
Lower perceived control (β = 0.30, p < .01), and higher levels of depression (β = -0.30, p < .01) and anxiety (β = -0.18, p < .05) predicted lower levels of HRQOL. Higher anxiety (β = -0.17, p < .05), higher depression (β = -0.23, p < .05), lower social support (β = 0.26, p < .01), and higher ICD-related concerns (β = -0.16, p < .05) independently predicted lower perceived control.
Interventions targeting patients' ICD concerns and psychosocial factors before, and continuing after, ICD insertion are needed to improve ICD recipients' perceived control and, in turn, their HRQOL.
在慢性病患者中，感知控制与健康相关的生活质量（HRQOL）密切相关，并且可以通过适当的干预来提高感知控制。在植入式心脏复律除颤器（ICD）接受者中，感知控制与 HRQOL 之间的关系知之甚少。
确定感知控制与 ICD 接受者生活质量之间的关系，并确定该人群中感知控制的预测因素。
共有 263 名 ICD 接受者（63%为男性，年龄 61±14 岁）完成了修订后的控制态度量表，以衡量感知控制，并完成了感知控制潜在相关因素的自我报告测量（即抑郁症状、焦虑、社会支持和 ICD 担忧）。EuroQol-5D 用于衡量 HRQOL。回归分析用于确定感知控制的预测因素及其与 HRQOL 的关系，同时控制协变量。
较低的感知控制（β=0.30，p<0.01）、较高的抑郁（β=-0.30，p<0.01）和焦虑（β=-0.18，p<0.05）水平预测 HRQOL 水平较低。较高的焦虑（β=-0.17，p<0.05）、较高的抑郁（β=-0.23，p<0.05）、较低的社会支持（β=0.26，p<0.01）和较高的 ICD 相关担忧（β=-0.16，p<0.05）独立预测感知控制较低。
需要在 ICD 植入前、植入期间和植入后针对患者的 ICD 关注点和心理社会因素进行干预，以提高 ICD 接受者的感知控制，进而提高他们的 HRQOL。
