title: Experiential avoidance and emotion regulation difficulties in hoarding disorder.
abstract: Experiential avoidance can be defined as the tendency to avoid contact with unwanted internal experiences. Current conceptualizations of pathological hoarding appear broadly consistent with an experiential avoidant model. Eighty participants in four groups, namely hoarding disorder (HD) without comorbid obsessive-compulsive disorder (OCD), HD with comorbid OCD, non-hoarding OCD, and healthy controls, were administered measures of experiential avoidance and emotion regulation difficulties. Hoarding individuals reported higher levels of experiential avoidance and difficulties in emotion regulation compared to healthy but not to OCD participants. Both experiential avoidance and emotion regulation difficulties were significantly more prominent when HD was comorbid with OCD than when HD occurred without comorbid OCD. Correlation analyses further showed that both experiential avoidance and emotion regulation were moderately but significantly associated with obsessive-compulsive but not hoarding symptoms. Thus, experiential avoidance and emotion regulation difficulties are not specifically relevant to HD but to a broad range of psychopathologies. However, despite the lack of specificity, the findings raise some potentially useful clinical implications for the treatment of HD.
