The Inventory of Children's Individual Differences: Development and Validation of a Short Version

Abstract

As more researchers utilize the Five-factor model (FFM) of personality with children and adolescents, the need for instruments designed specifically for use with children and adolescents increases. In the United States, the 108-item Inventory of Children's Individual Differences (ICID; Halverson et al., 2003), has provided researchers with an age and culture neutral instrument designed specifically to assess the FFM of personality in children and adolescents, ages 2 to 15, using parental, nonparental, or self-reports. This article presents a shorter, 50-item version of the ICID (the ICID-S) that maintains the levels of validity and reliability previously established for the full instrument.
