The French Version of the Reflective Functioning Questionnaire: Validity Data for Adolescents and Adults and Its Association with Non-Suicidal Self-Injury

The present research has methodological and clinical implications in that it provides the first evidence that the RFQ can be used to reliably assess reflective functioning in French-speaking population. The study further shows that impaired ability to consider mental states that lie behind behaviors might play a role in non-suicidal self-injury, at least in adults.
