Psychometric Characteristics of Quay-Peterson Revised Behavior Problem Checklist

This study was conducted to investigate psychometric characteristics of Quay-Peterson Revised Behavior Problem Checklist. The core of this study was scale development and 458 schoolchildren (255 boys and 203 girls) from elementary schools, of four educational districts in the city of Shiraz (Iran) were recruited using cluster random sampling method. The subjects were then assessed using Quay-Peterson Revised Behavior Problem Checklist. The validity of the checklist was obtained using item-total correlations, factor analysis and the correlation between the checklist scores and Rutter Children Behavior Questionnaire total score (0.88). Factor analysis using principle component analysis followed by varimax rotation led to the extraction of four factors with eigenvalues of greater than one which included: conduct disorder, attention problems-immaturity, social aggression and anxiety-withdrawal. The reliability of the scale using test-retest was as follows: 0.88 for total score, 0.90 for conduct disorders, 0.85 for attention problems- immaturity, 0.79 for social aggression, and 0.78 for anxiety-withdrawal. Cronbach alpha coefficients were 0.98, 0.97, 0.97, 0.82, and 0.85 for the total score, conduct disorder, attention problems-immaturity, social aggression and anxiety-withdrawal respectively. Quay-Peterson Revised Behavior Problem Checklist is a valid and reliable instrument for use in Iran.
