It was hypothesized in this document that lowered self-concept would be associated with children exhibiting problems such as delinquency or childhood depression. The differences in self-concept between 97 clinic and 485 nonclinic children were investigated by administration of the Piers-Harris Children's Self Concept Scale. The reported self-esteem of both groups were compared using analysis of variance techniques. Results indicated that the clinic sample had significantly lower self-concept scores on the total scale and on five of the six cluster scales than did the nonclinic group. The clinic group had higher self-concept scores on 7 of the 80 individual items; these may represent a combination of compensatory behavior and denial. (Author/DWH)
