Application et efficacité d'une thérapie basée sur les inférences auprès d'une population d'accumulateurs compulsifs: une étude de cas clinique
Studies shows that there is about 4% hoarders in the population (Samuels et al., 2008). Consequences on their lives are high, hoarding could lead to break up, loss of jobs and mental and physical health issues (Frost et al., 2000; Frost et Gross, 1993; Frost et Hartl, 1996; Tolin, Frost, Steketee, Gray et Fitch, 2008). Treatments have been tried on hoarders, including a special design of cognitive behavioral therapy. Unfortunately, treatments success are low, hoarders seemed refractary to treatment (Steketee, Frost, Tolin, Rasmussen, Brown, 2010). It’s what led Kieron O’Connor to try to adapt his cognitive approach, the inference based therapy, to hoarders.   The goal of this project is to evaluate the faisability of an inference based therapy with hoarders. Nine people who received an inference based therapy for hoarding between 2003 and 2014 at the Centre de Recherche de l’Institut Universitaire en Santé Mentale de Montréal were evaluate. Two of them were studied in depth in clinical case studies. We found a clinically significant decrease at 66% of the sample (n=9). Four of them were sub clinical and one of them had light symptoms of hoarding on the Y-BOCS at the end of therapy. Fifty-six percent had a clinically significant decrease of their depressive symptoms and 33% of their anxious symptoms. An effect size of 0,8 for the Y-BOCS, 0,3 for the BDI and of 0,2 for the BAI were found.
