In DSM-IV-TR, trichotillomania (TTM) is classified as an impulse control disorder (not classified elsewhere), skin picking lacks its own diagnostic category (but might be diagnosed as an impulse control disorder not otherwise specified), and stereotypic movement disorder is classified as a disorder usually first diagnosed in infancy, childhood, or adolescence. ICD-10 classifies TTM as a habit and impulse disorder, and includes stereotyped movement disorders in a section on other behavioral and emotional disorders with onset usually occurring in childhood and adolescence. This article provides a focused review of nosological issues relevant to DSM-V, given recent empirical findings. This review presents a number of options and preliminary recommendations to be considered for DSM-V: (1) Although TTM fits optimally into a category of body-focused repetitive behavioral disorders, in a nosology comprised of relatively few major categories it fits best within a category of motoric obsessive–compulsive spectrum disorders, (2) available evidence does not support continuing to include (current) diagnostic criteria B and C for TTM in DSM-V, (3) the text for TTM should be updated to describe subtypes and forms of hair pulling, (4) there are persuasive reasons for referring to TTM as “hair pulling disorder (trichotillomania),” (5) diagnostic criteria for skin picking disorder should be included in DSM-V or in DSM-Vs Appendix of Criteria Sets Provided for Further Study, and (6) the diagnostic criteria for stereotypic movement disorder should be clarified and simplified, bringing them in line with those for hair pulling and skin picking disorder.

    • "In this model, the behavioral components (avoidance, obsessive and safety behaviors)—the cognitive components (core beliefs, intermediate beliefs, automatic thoughts)—the metacognitive components (positive and negative metacognitive beliefs and metacognitive strategies) have been considered in explaining SPD. The findings of the study are consistent with (Stein et al., 2010) in terms of the relationship between cognitive components and SPD. Among the reasons for this relationship, it can be noted that in these patients the underlying beliefs are more general, inflexible, rigid, negative and irrational that cause mind's natural processes associate with cognitive distortions, leading to an increase in negative automatic thoughts in these patients.

    ABSTRACT: The purpose of the present study is to provide an overview of the disorder and develop a new be-havioral-cognitive-metacognitive model to explain it. The present study is a descriptive-correla-tional research which uses the structural equation model. In this study, at first, a comprehensive and detailed explanation of skin picking disorder is presented. Then the conceptual model is presented and finally, the model which is developed by using structural equation model is tested by Amos Graphics. The results of the structural equation model showed that the developed model in this study is able to explain skin picking disorder. Also the results of the overall fit indices for structural equation modeling show that the developed model has good fit to the sample data and is closely associated with the theoretical assumptions. Since the model presented in this study is multi-dimensional and takes into consideration all of the three behavioral, cognitive, metacogni-tive dimensions and these three dimensions are considered interdependent and not dependent and contradictory, it is considered as a new explanatory model. The model may prompt future researches into skin picking disorder and facilitate clinical treatments and case formulations associated with this disorder.

    • "According to some authors, OCD and ED are therefore phenotypic expressions of the same liability (Anderluh, Tchanturia, Rabe-Hesketh, & Treasure, 2003; Bellodi et al., 2001; Jacobi, Hayward, de Zwaan, Kraemer, & Agras, 2004). Another OC spectrum condition, hair-pulling disorder (HPD), shares a number of features with OCD (Grant, Mancebo, Pinto, Eisen, & Rasmussen, 2006; Stein et al., 2010). Typically, it is characterized by repetitive behaviors resembling tic-like behaviors or compulsions; sometimes they are preceded by an urge to pull and followed by a sense of relief or are preceded by obsessive thoughts, even though this is not true for all patients (Chamberlain, Fineberg, Blackwell, Robbins, & Sahakian, 2006; Ferrão, Almeida, Bedin, Rosa, & D'Arrigo Busnello, 2006; Lochner et al., 2005; for a thorough description of the disorder as well its associated features, see Ghisi, Bottesi, Sica, Ouimet, and Sanavio (2013)).

    ABSTRACT: Not Just Right Experiences (NJREs) are considered to be a perceptually tinged phenomenon mainly related to obsessive-compulsive disorder (OCD). The evidence of an association between NJREs and OCD or OC symptoms have been accumulating in the last few years, whereas there is a paucity of studies about the role of this construct in other clinical conditions considered part of the "OCD spectrum". In the current study, the NJRE-Q-R Severity scale (a well-validated measure of NJREs) was administered to 41 patients with OCD, 53 with hair-pulling disorder (HPD), 38 with gambling disorder (GD) and 43 with eating disorders (ED) along with measures of OC symptoms and general distress. In each group, NJREs were consistently associated with OC symptoms; moreover, the pattern of associations appeared coherent with the main clinical features of each disorder. The OCD group reported higher levels of NJREs severity than GD and ED, whereas there were no differences between the OCD and HPD groups. However, HPD patients did not have higher scores of NJREs severity than GD and ED counterparts. NJREs appear to be specific to OCD, but further study is needed to establish the role of this construct in OCD-related disorders. Copyright © 2015. Published by Elsevier Ltd.

    • "Hair pulling behaviors are common in the general population (Duke et al., 2009), with between 1% and 3% of adults reporting clinically significant hair pulling (Christenson et al., 1991b). Hair pulling disorder, commonly referred to as trichotillomania (TTM), is characterized by excessive hair pulling that can be automatic (e.g., outside of awareness) or focused (e.g., consciously pulled) in nature (American Psychiatric Association, 2013; Stein et al., 2010). Individuals with TTM frequently experience co-occurring anxiety disorders, depressive disorders, and other body-focused repetitive behaviors (Duke et al., 2010; Panza et al., 2013). "

    ABSTRACT: Few randomized controlled trials (RCTs) exist examining the efficacy of behavior therapy (BT) or serotonin reuptake inhibitors (SRIs) for the treatment of trichotillomania (TTM), with no examination of treatment moderators. The present meta-analysis synthesized the treatment effect sizes (ES) of BT and SRI relative to comparison conditions, and examined moderators of treatment. A comprehensive literature search identified 11 RCTs that met inclusion criteria. Clinical characteristics (e.g., age, comorbidity, therapeutic contact hours), outcome measures, treatment subtypes (e.g., SRI subtype, BT subtype), and ES data were extracted. The standardized mean difference of change in hair pulling severity was the outcome measure. A random effects meta-analysis found a large pooled ES for BT (ES= 1.41, p< 0.001). BT trials with greater therapeutic contact hours exhibited larger ES (p= 0.009). Additionally, BT trials that used mood enhanced therapeutic techniques exhibited greater ES relative to trials including only traditional BT components (p= 0.004). For SRI trials, a random effects meta-analysis identified a moderate pooled ES (ES= 0.41, p= 0.02). Although clomipramine exhibited larger ES relative to selective serotonin reuptake inhibitors, the difference was not statistically significant. Publication bias was not identified for either treatment. BT yields large treatment effects for TTM, with further examination needed to disentangle confounded treatment moderators. SRI trials exhibited a moderate pooled ES, with no treatment moderators identified. Sensitivity analyses highlighted the need for further RCTs of SRIs, especially among youth with TTM.
