The demand-control (D-C) model of job strain has generated a considerable body of empirical support in predicting psychological health outcomes in the context of work. This study aimed to extend previous work using the D-C model of job strain to predict caregiver burden and satisfaction in the informal caregivers of patients with heart failure.
Data were gathered from 60 caregiver/patient dyads in a cross-sectional design. Patients with chronic stable heart failure were recruited from out-patient clinics. The dependent variables were caregiver burden and satisfaction. Demand and control were measured using both patient- and caregiver-derived measures.
The D-C model accounted for 15 and 19% of the variance in caregiver burden, after controlling for age, gender and relationship to the patient. Lower control was associated with higher burden. The D-C model did not predict caregiver satisfaction.
The D-C model was associated with caregiver burden, but not satisfaction in caregivers, with control being the dominant predictor. Research linking the theory and findings from job strain and informal caregiving studies may elucidate both fields of research. Using the demand-control model of job strain to predict caregiver burden and caregiver satisfaction in the informal caregivers of heart failure patients.
工作要求-控制（D-C）模型在预测工作情境中的心理健康结果方面已获得大量实证支持。本研究旨在扩展先前的工作，运用工作要求-控制模型来预测心力衰竭患者非正式照料者的照料负担和满意度。
采用横断面设计，从60对照料者/患者二元组中收集数据。慢性稳定型心力衰竭患者从门诊招募。因变量为照料者负担和满意度。使用源自患者和照料者的测量方法来衡量要求和控制。
在控制了年龄、性别以及与患者的关系后，D-C模型解释了照料者负担中15%和19%的方差。较低的控制与较高的负担相关。D-C模型未预测照料者满意度。
D-C模型与照料者负担相关，但与照料者满意度无关，控制是主要预测因素。将工作压力理论与非正式照料研究的结果联系起来的研究可能会阐明这两个研究领域。运用工作要求-控制模型预测心力衰竭患者非正式照料者的照料负担和照料者满意度。
