The relationship between perceived loss of control and passivity in social activities in a non-handicapped institutionalized elderly population was assessed. Perceived loss of control was assessed from three different types of expectancies: low action-outcome expectancies, high situation-outcome expectancies, and low efficacy expectancies. Passivity scores were reported by the staff. The effect of these three types of expectancies on passivity was analyzed in terms of motivation and volition, which were treated as mediating variables. Overall analysis of the structural equations, as well as partial hierarchical regression analyses, showed that efficacy expectancies were good predictors of passivity, but this was not the case for the action-outcome and situation-outcome expectancies. These results lend more support to a volitional rather than to a motivational interpretation of the effect of control on passivity. The implications of these results for intervention and for a differentiated conception of expectancies are discussed.
研究评估了非残疾机构养老人群中感知到的控制感丧失与社交活动中的被动性之间的关系。从三种不同类型的期望来评估感知到的控制感丧失：低行动-结果期望、高情境-结果期望和低效能期望。被动性得分由工作人员报告。从动机和意志方面分析了这三种期望对被动性的影响，动机和意志被视为中介变量。结构方程的总体分析以及部分分层回归分析表明，效能期望是被动性的良好预测指标，但行动-结果期望和情境-结果期望并非如此。这些结果为控制对被动性影响的意志性解释而非动机性解释提供了更多支持。讨论了这些结果对干预以及期望的差异化概念的意义。
