The purposes of this study were (a) to construct and validate a Stunt Movement Confidence Inventory (SMCI) that would reliably discriminate between high- and low-confidence children and (b) to examine perceived confidence in light of assumptions from the movement confidence model. Interaction of three components postulated in the model (competence, potentials for enjoyment, and harm) was studied by analyzing the response patterns of 356 children. Reliability coefficients for item, subscale, total scale, and subject stability ranged from r=.79 to .93. SMCI subscales successfully classified 88% of all subjects with a 52.3% improvement over chance and a validity coefficient of .98. The factor matrix accounted for 49% of the total variance and verified the dominance of the competence subscale and the multivariate nature of the harm variable (subscale). Response profiles of low- and high-confidence groups validated the identity and separability of the model's theoretical components—competence, enjoyment, and harm. The SMCI was reliable and valid in discriminating between high- and low-confidence children.
