title: Affective correlates of trichotillomania.
abstract: Affective correlates of hair pulling were investigated in a sample of 44 participants diagnosed with trichotillomania (TM). Participants completed the Hair Pulling Survey on which they rated the intensity of ten different affective states across three different phases of hair pulling (before, during and after). Repeated measures analysis of variance was used to examine the change of emotional experience across the hair pulling cycle. Results indicated significant decreases in boredom, anxiety and tension, and significant increases in guilt relief, sadness and anger across time (p<0.005). The role of co-existent anxiety and mood disorders also was examined using repeated measures analysis of variance. Results of these analyses indicated that patients with and without co-existent disorders differed only on patterns of anger across time, and therefore do not support affective subtypes of TM patients based on co-existent diagnosis. Implications of these findings for conceptualization and treatment of TM are discussed.
