Efficacity of Psychological Intervention on Reducing the Suicidal Ideations, Depression Level and Improving Reinsertion

Suicide is the third leading cause of death in adolescents and young adults in the United States and the second leading cause in European countries. Depressive disorders are consistently the most prevalent psychiatric disorder among adolescents who attempt suicide with a prevalence ranging from 49% to 64%. Depression in adolescent and young adults is a multifactorial phenomenon, as is the risk of suicidal attempt. To address such problems, effective and accessible treatment is needed, as recommended by the French Health Authority (HAS). Our primary objective is to demonstrate that a weekly psychotherapeutic intervention reduces the depression level. The primary assessment criterion is the variation of the clinician Adolescent Depression Rating Scale (ADRSc) from randomisation to month 6. The study also aims comparing in the 2 randomised groups * ADRS depression global score (clinician and subject) at 0, 3, 9 and 12 months * Number of suicidal attempts and self-harm attempts at 6 and 12 months * Number of drop-out at 6 and 12 months * Beck's Hopelessness Scale at 0, 3, 6, 9 and 12 months * Global score on the GHQ-28 and scores on the 4 subscales (Somatization, Anxiety and Insomnia, Social dysfunction, Depressive mood) at 0, 3, 6, 9 and 12 months. * Working AIliance Inventory (WAI) score at 0, 3, 6, 9 and 12 months
