The present study examined the factor structure, internal consistency, and construct validity of the parent version of the Social Competence and Behavior Evaluation-30 for preschoolers (SCBE-30; LaFreniere, P. J. (1990). Social competence and behavior evaluation-30. Unpublished measure.), an adaptation of the validated teacher version of the same measure (LaFreniere & Dumas, Psychol. Asses. 8 (1996) 369). The parent version of the SCBE-30 is a 30-item Likert rating scale questionnaire designed to assess patterns of anxiety/withdrawal, anger/aggression, and social competence. Principal components analysis was used to identify the factor structure of the parent version of the SCBE-30 (N = 218 preschool children). To assess construct validity, a compliance task was utilized to determine whether children identified as high on anxiety/withdrawal, anger/aggression, or social competence with the parent version of the SCBE-30 (n = 20 for each group) could be distinguished behaviorally on several observational variables. Principal components analysis identified three factors accounting for 44% of the variance. Ten items positively loaded onto each factor and matched conceptual expectations. A between-subjects MANOVA demonstrated significant group differences in observed child behaviors including compliance, noncompliance, subtypes of noncompliance, and aversive behavior. Results of the current study suggested that the parent version of the SCBE-30 demonstrated both internal consistency and construct validity, and findings paralleled many of the results from LaFreniere and Dumas' validation of the teacher version of the SCBE-30.
