Data were collected from 140 caregivers of elderly relatives, their husbands, and coresident children. Lawton et al.'s (1991) parallel channel hypothesis, which suggests that positive and negative aspects of mental health have differential predictors, was tested. Data from caregivers, their husbands, and children support the hypothesized model, with greater interdependence of psychological process being associated with greater role centrality.
数据收集自140名老年亲属的照料者、他们的丈夫以及同住的子女。对劳顿等人（1991年）的平行通道假说进行了检验，该假说认为心理健康的积极和消极方面有不同的预测因素。来自照料者、他们的丈夫和子女的数据支持了假设模型，心理过程的相互依赖性越强，角色中心性就越高。
