The childhood trauma questionnaire in a community sample: psychometric properties and normative data

Interpretation of research on the prevalence and sequelae of childhood trauma has been hindered by the use of assessment instruments with unknown psychometric properties. Thus, we examined the psychometric properties of a new childhood trauma measure, the Childhood Trauma Questionnaire (CTQ). The CTQ has demonstrated strong psychometric properties in clinical samples; limited information exists on its psychometric properties in community samples. Therefore, we explored the factor structure and reliability of the CTQ in a community sample and calculated normative data. Consistent with previous literature, a 5-factor model best described the CTQ, with a hierarchical model also providing excellent fit. Additionally, the CTQ demonstrated acceptable internal consistency. Overall, our findings suggest that the CTQ is appropriate for use in a community sample.
