| Abstract: | Perceived control plays a central role in many motivational and cognitive accounts of behavior. In this study, a new 48-item self-report instrument, the Multidimensional Measure of Children's Perceptions of Control, is described. Perceptions of control are defined as children's understanding of the locus of the sufficient cause for success and failure outcomes. 3 dimensions of third- through ninth-grade children's perceptions of control are independently assessed: internal, powerful others, and unknown. Each of these sources of control is assessed within 3 behavioral domains: cognitive, social, and physical. General items are also included. Perceptions of control over success outcomes and failure outcomes are assessed separately. The psychometric properties of the new measure's subscales are presented. Correlations of the new measure with measures of perceived and actual competence and findings demonstrating the sensitivity of the new measure to developmental, gender, and environmental influences are reported. It is argued that the new measure is an advance over existing measures of internal versus external locus of control in children because it provides domain-specific assessments of 3 separate dimensions of locus of control, including the previously untapped dimension of unknown control. |
