The Externalizing Spectrum Inventory (ESI) was designed for assessing a broad spectrum of externalizing problems, including impulsive-aggressive behavior and substance abuse. After translation of the ESI into Dutch, a computerized version of the full Dutch ESI (ESI-NL) was administered to a mixed sample consisting of inpatients in forensic and addiction care (n=99) and non-psychiatric community participants (n=104). Internal consistencies, test-retest reliabilities, predictive' validity of the full and 160-item ESI-NL total scores and subscales were examined, along with the correlations between these two versions. The results indicated high reliability and predictive validity for both versions and a strong similarity between the two in direct comparisons. The 160-item Dutch ESI is recommended for clinical studies on violence proneness and externalizing problem behavior.
