An item response theory analysis of the Impulsive Behaviors Checklist for Adolescents.
This study used item response theory (IRT) to examine the Impulsive Behaviors Checklist for Adolescents (IBCL-A) among 6,276 (67.7% girls) Chinese secondary school students. The IBCL-A included 15 maladaptive impulsive behaviors adapted from the Revised Diagnostic Interview for Borderlines. The authors obtained the severity and discrimination parameters for each item in the IBCL-A, examined differential item functioning across gender and age groups, and tested reliability and concurrent validity of the IBCL-A IRT-scaled score. Most items in the IBCL-A were the most accurate in assessing moderate to high levels of impulsivity and discriminated well among adolescents with varied levels of impulsivity. Differential item functioning emerged in several items across gender. The IRT-scaled score showed good construct validity and incremental predictive validity. Findings demonstrate the sound psychometric properties of the IBCL-A and support the clinical utility of this scale.
