Trichotillomania and skin picking disorder have also historically been classified, by some, as types of compulsive self-injury as they involve repetitive hair pulling and skin picking, respectively. The question of the relationship of these disorders to more conventional forms of self-injury such as cutting or self-burning remains incompletely investigated. The objective of this study was to examine the relationship of these two disorders with non-suicidal self-injury (NSSI).<\/jats:p><\/jats:sec><jats:sec id=\"S1092852924000294_sec2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>Adults with trichotillomania (n\u00a0=\u00a093) and skin picking (n\u00a0=\u00a0105) or both (n\u00a0=\u00a082) were recruited from the general population using advertisements and online support groups and completed an online survey.
