Falkenstein MJ, et al. - Here, the researchers examined sensory-over responsivity (SOR) to external sensations among individuals with trichotillomania (TTM). By contributing the first data about associations between TTM and over-responsivity to external sensations, the findings expanded prior work in obsessive-compulsive related disorders. The outcomes suggested that in TTM, SOR could be related to maladaptive emotion regulation processes. In this study, a novel measure of SOR was developed and administered.
