The main objective of this study is to develop the French version of the two questionnaires AIDA and LoPF-Q. The secondary objective is to investigate the links between disrupted development of identity and adolescent psychopathology.

To participate in the study, patients will have to complete online or paper versions of the questionnaires AIDA-LoPF and other assessments of personality and general psychopathology (BB5, SDQ). Parents will have to answer complete the parent version of the SDQ questionnaire. The BPFSC-11, which is a clinician-rated assessment, will be completed in a subgroup of patients, by the same healthcare professional, in order to assess the concurrent validity. The investigators will also add the clinical diagnoses according to ICD-10 found in the medical record.

A personality disorder is a lasting mode of behavior and lived experience that deviates significantly from what is expected in the culture of the individual is invasive and rigid, appears in early adolescence or adulthood, is stable over time and is a source of distress or impaired functioning.

Most of the tools for assessing high-risk personality disorders and traits have been developed in adults.Yet it is important to have effective tools to distinguish personality disorders from other mental disorders as early as possible. The identification of young people at high risk of personality disorders allows their rapid referral to appropriate psychotherapies.

The AIDA and LoPF-Q, screening questionnaires, were recently developed to include an assessment of personality functioning in the process of diagnosing emotional and behavioral disorders in adolescence. They have been tested in several countries such as Germany, USA, Mexico, Croatia… The results of the studies show that AIDA and LoPF questionnaires are reliable and valid instruments for assessing normal and disturbed identity in adolescents and distinguishes well between patients with psychiatric illnesses and healthy controls.
