Construct Validation of the Piers-Harris Children's Self Concept Scale

An investigation was conducted to determine the construct validity of the Piers-Harris Children's Self Concept Scale (P-H). Evidence for the validity of the instrument was analyzed according to the model for construct validation proposed by Sabers and Whitney. The main parameters of the model include the convergent validity, discriminant validity, internal consistency, and stability of the measure. Results indicated that the P-H demonstrates both convergent and discriminant validity in an assessment of a relatively stable and internally consistent construct.
