Development and validation of a self-report measure assessing failures in the mentalization of trauma and adverse relationships.

Abstract:

<p><b>BACKGROUND: </b>The way people process trauma and adverse relationships may be more predictive of subsequent adaptation than trauma exposure in itself. However, there is currently no self-report instrument assessing failures in the mentalization of trauma and adverse relationships.</p><p><b>OBJECTIVE: </b>We developed the Failure to Mentalize Trauma Questionnaire (FMTQ) and evaluated its psychometric properties. The FMTQ is a 29-item self-report instrument designed to assess different indications of failures in the mentalization of trauma and adverse relationships.</p><p><b>PARTICIPANTS AND SETTING: </b>A total of 975 participants (84 % women; 37 % exposed to child maltreatment) were recruited in the course of larger research protocols on parenting.</p><p><b>METHODS: </b>Participants completed the FMTQ and measures of childhood maltreatment, psychopathology (post-traumatic stress symptoms, dissociative symptoms, level of personality dysfunction), general mentalization and intimate partner violence.</p><p><b>RESULTS: </b>Exploratory factor analysis, supported by a confirmatory factor analysis, identified seven factors with good internal consistency that corresponded to different types of failures in the mentalization of trauma and adverse relationships and that loaded on a general factor. A dose-effect association was observed between the severity of childhood maltreatment, and the severity of failures in the mentalization of trauma and adverse relationships (r = .49, p < .01). The FMTQ total score explained a significant proportion of variance in psychopathology and intimate partner violence, both in participants with histories of childhood maltreatment and participants without childhood maltreatment.</p><p><b>CONCLUSION: </b>The FMTQ is a promising, concise and efficient measure of failures in the mentalization of trauma and adverse relationships that may facilitate clinical screening and research with adults who experienced trauma.</p>
