Evaluation of Efficiency of One Day Patient/Caregiver Psychoeducation on the Caregiver's Burden

Bipolar disorder (BD) has a huge impact on patient lives and their relatives. BD psychoeducation has been shown to be effective on patient disease course and caregivers burden. However, the programs offered appear to be incompatible with the participants obligations and services requirements. In this context we wanted to develop a "minute" program (Bp one day). Study participation includes 3 visits : inclusion visit and 2 follow up visits. The main objective is to assess the effectiveness of day psychoeducational program (BP OneDay) on caregiver burden at one month according to the Zarit Caregiver Burden Interview (ZCBI) total score. This study also aims to assess the effectiveness of BP OneDay on caregiver stigma, patient self-stigma and medication adherence, quality of life, and bipolar disorder knowledge. The study is an open-label randomized controlled trial with two arms Overall, 120 dyads will be recruited randomly affected in 2 groups : * the interventional group will benefit from a day psychoeducational program : Bp oneDay * the control group will be placed on the waiting list The benefits expected from Bp OneDay are to reduce caregiver burden and stigma and improve knowledge about BD. For patients, we expect improve disease understanding, drug adherence and reduce self-stigmatization. If the results are promising, this program can be widely disseminated and thus increase cares' solution for patients and relatives in large urban centers.
