A VALIDATION STUDY OF THE RUSSIAN VERSION OF THE ADVERSE CHILDHOOD EXPERIENCES INTERNATIONAL QUESTIONNAIRE (ACE-IQ) IN A SAMPLE OF DRUG USERS
The Adverse Child Experiences International Questionnaire (ACE-IQ) is globally recognized as a key tool for assessing cases of child abuse and neglect. The aim of this study was to develop a Russian version of the ACE-IQ and validate it in patients with substance use disorder. The original English version of the ACE-IQ was translated into Russian and then the Russian version was applied in 402 substance users. To assess the psychometric reliability of ACE-IQ factor structure, an exploratory and confirmatory factor analysis was conducted. It was found that the total score of ACE-IQ and 13 categories of adverse child experiences had adequate homogeneity. Sufficient internal consistency was identified for the categories that determine most forms of adverse childhood experiences. These findings also showed that the alternative factor structure, unlike the original one, is the most appropriate model for the Russian sample of substance users. In general, the study provides evidence of the validity and reliability of the Russian version of ACE-IQ.
