Equivalence of computerized and standard administration of the Piers-Harris Children's Self-Concept Scale

Two hundred seventy-nine 8- to 17-year-old children and adolescents were randomly assigned to complete paper-and-pencil or computer-administered versions of the Piers-Harris Children's Self-Concept Scale. The equivalence of these two administration modes was assessed by evaluating the comparability of scale means, variances, reliabilities, and validities. Results indicate that, of 27 comparisons, only 1 produced a statistically significant difference. We concluded that the computerized administration of the Piers-Harris scale did not affect its psychometric properties and that paper-and-pencil and computerized modes of testing for this questionnaire may be regarded as equivalent.
