Psychometric Properties of the Dutch Eyberg Child Behavior Inventory (ECBI) in a Community Sample and a Multi-Ethnic Clinical Sample.

The Eyberg Child Behavior Inventory (ECBI) is an established parent rating scale to measure disruptive behavior problems in children aged between 2 and 16 years. The present study examined the psychometric properties of the Dutch translation, including analysis on the one-dimensional structure of the ECBI scales using item response theory. Data from two samples from the Netherlands were used, a community sample (N = 326; 51 % boys) and a multi-ethnic clinical sample (N = 197; 62 % boys). The one-dimensional structure of the ECBI Intensity and Problem Scales were confirmed in both of these samples. The results also indicated good internal consistency, test-retest reliability (community sample), and good convergent and divergent validity. The ECBI Intensity Scale was able to differentiate between diagnostic groups (no diagnosis, ADHD, ODD, and CD symptoms), demonstrating good discriminative validity. Findings support the use of the ECBI as a reliable measure for child disruptive behavior problems in a Dutch population. Suggestions for the optimal use of the both ECBI scales for research and screening purposes are made. Also, cultural issues regarding the use of the ECBI are discussed and additional research into the validity of the ECBI is recommended.
