The relationship between social behavior, as measured by the School Social Behavior Scales (SSBS), and self-concept, as measured by the Self-Perception Profile for Children (SPPC), was studied. Subjects included 41 public school students in Grades 5 and 6. These subjects were rated on the SSBS by their classroom teachers and also completed the SPPC as a self-report measure. A number of ... [Show full abstract] significant positive relationships were found between the Social Competence scores of the SSBS and the SPPC self-concept scores. Relationships between the Problem Behavior scores of the SSBS and the SPPC scores were extremely weak, and none of the obtained coefficients was statistically significant. The pattern of associations identified through this investigation provides support for the criterion-related validity of both the SSBS and SPPC, and raises some interesting questions regarding the relationship between social behavior and self-concept in children.
