STANDARDIZATION OF A JAPANESE VERSION OF THE YOUTH SELF-REPORT FOR SCHOOL AGES 11-18

Abstract

Objective: This study was designed to standardize a Japanese version of the Youth Self-Report (School Ages 11-18 years) based on standardization protocol used for the original Achenbach System of Empirically Based Assessment (ASEBA).

Method: We divided 889 participants into two groups based on gender: 440 boys and 449 girls. T scores were calculated from the raw scores of all scales: anxious/depressed, withdrawn/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behaviors, aggressive behaviors, Internalizing, Externalizing, and Total problems. Scale reliability and validity were assessed with Cronbach's alpha coefficient, inter-correlations, and by comparison with the high-functioning Autism Spectrum Screening Questionnaire (ASSQ). Effects of gender were tested by regression analysis of the syndrome scales.

Results and Conclusion: Results showed that the total average Cronbach's alpha was .81, indicating good internal consistency. Additionally, validities were confirmed by significant positive correlation between all scales as well as with the ASSQ. Results of regression analysis showed significant effect of “boys” on “attention problems,” “rule-breaking behavior,” and “aggressive behavior.”
