The Piers-Harris Children's Self-Concept Scale-Second Edition (Piers-Harris 2) was designed to measure self-concept among children and adolescents. This study aimed to assess the reliability and validity of the scores of the Chinese version of the Piers-Harris 2 (Chinese Piers-Harris). The Chinese Piers-Harris 2 was administered to 243 Taiwanese students in Grades 1 to 4. The results of factor analysis indicated a six-factor promax solution was the most appropriate solution for the Chinese Piers-Harris 2. The results also revealed acceptable internal consistency and test score stability of the Chinese Piers-Harris 2 scores. In addition, the scores of the Chinese Piers-Harris 2 had significant correlations with the scores of the Elementary School Children's Self-Concept Scale and the Behavioral and Emotional Rating Scale. Overall, the findings indicate that the Chinese Piers-Harris 2 scores have good psychometric properties for a sample of Taiwanese children.

A multimedia version of Piers-Harris Children's Self-Concept Scale 2 (Piers-Harris 2) was created with audio and cartoon animation to facilitate the measurement of self-concept among younger children. This study aimed to assess the psychometric qualities of the computer version of Piers-Harris 2 scores, examine its score equivalence with the paper-and-pencil version, and survey the respondent preference of the two versions. Two hundred and forty eight Taiwanese students from the first to fourth grade were recruited. In regard to the psychometric properties, high internal consistency (α = .91) was found for the total score of multimedia Piers-Harris 2. High interscale correlations (.77 to .83) of the multimedia Piers-Harris 2 scores and the results of confirmatory factor analysis suggested the multimedia Piers-Harris 2 contained good structural characteristics. The scores of the multimedia Piers-Harris 2 also had significant correlations with the scores of the Elementary School Children’s Self Concept Scale. The equality of convergence and criterion-related validities of Piers-Harris 2 scores for the multimedia and paper-and-pencil versions and the results of ICCs between the scores of the multimedia and paper-and-pencil Piers-Harris 2 suggested their high level of equivalence. Participants showed more positive attitudes towards the multimedia version.
