Basic Psychometric Properties of the Preschool and Kindergarten Behavior Scales in a Sample of Iranian Children

This study was aimed to determine the basic psychometric properties of Preschool and Kindergarten Behavior Scales (PKBS, Merrell, 2002) in a sample of Iranian children aged 4 6-years (402 children of both sexes). Results show internal consistency of scores on social skills (. 87) and problem behavior (. 92) scales. An exploratory factor analysis was performed using a varimax rotation. Five factors were extracted in the social skills scale: (1) social interaction, (2) social cooperation, (3) social participation, (4) social independence, (5) self-control/ social convention and six factors were extracted in the problem behavior scale: (1) attention problems/ overactive, (2) antisocial/ aggressive, (3) social withdrawal, (4) self-centered, (5) hypersensitivity, (6) anxiety/ somatic problems.
