Analyzed data from 154 school-age children and their mothers to examine the relations between stress, perceived competence and contingency, and behavior symptoms. Analyses focused on the relative merits of unidimensional vs multidimensional measures of control in predicting symptoms. The stress of undesirable life events and behavior symptoms were related in the expected direction. Multiple regression models with R2 ranging from .11 to .14 (all ps less than .0002) included significant main effects for stress, competence, and control. Analyses supported the relative superiority of the multidimensional measure of control. Models containing main effects and interaction terms were of equivalent magnitudes in accounting for variance in symptom scores. Findings support the idea of perceived control as a moderator of the stress-illness relation and are consistent with earlier suggestions that simple main effects models may be the most useful in examining these relations.
分析了154名学龄儿童及其母亲的数据，以研究压力、感知能力和权变与行为症状之间的关系。分析聚焦于在预测症状方面，一维控制测量与多维控制测量的相对优点。不良生活事件的压力与行为症状呈预期方向相关。决定系数R2在0.11至0.14之间的多元回归模型（所有p值均小于0.0002）包含压力、能力和控制的显著主效应。分析支持了多维控制测量的相对优越性。包含主效应和交互项的模型在解释症状评分方差方面具有同等规模。研究结果支持了感知控制作为压力与疾病关系调节因素的观点，并且与早期的建议一致，即简单主效应模型在研究这些关系时可能是最有用的。
