French Validation of the Dual Diagnosis Screening Interview (F_DDSI)

In France, there are no tools for screening psychiatric comorbidities for individuals with Substance Use Disorders. The literature shows that the cooccurrence of these psychiatric disorders in the same individual is frequent. It negatively impacts the healing prognosis, complicates the diagnostic processes and the type of care to be introduced for patients. The creation of reliable, fast and easy-to-use tools for caregivers and researchers is therefore necessary to improve quantitatively and qualitatively the care of patients. There is a Spanish scale that meets these criteria, the Dual Diagnostic Screening Interview (S\_DDSI). The main objective of this study is to validate the DDSI in French. The secondary objectives are the evaluation of the psychometric qualities of F\_DDSI (French version) and adaptation of this scale into an application for Android and iOS.
