“…The DSM-IV HPD rate of 2.6% observed here in TS patients is also more than twice the reported DSM-IV HPD population prevalence of 1% [5], and comparable to the estimate of 2.6% from an international TS clinical registry [3]. Although previously reported rates are more variable for SPD, the 13% SPD prevalence rate found in this study represents a nearly two-fold increase over the highest reported estimates in non-clinical samples based on DSM-5 criteria (7.7%) [11], and a two-to-nine-fold increase over the more commonly accepted population rates of 1.4–5.4%. Given that HPD/SPD rates were higher in adolescent and adult TS patients than in children (Online Resource 1, Table S2; Figure S3), consistent with prior reports of an HPD and SPD peak onset in early adolescence [7, 8], these estimates may be conservative.…”

“…SPD prevalence has been similarly challenging to estimate, given its changing definition over time and its absence in the DSM until the most recent version, DSM-5 , published in 2013 [4]. Prior to 2013, studies of non-clinical samples have reported prevalence rates ranging from 1.4–5.4% [8–10]; current DSM-5 estimates range as high as 7.7% [11]. As in HPD, SPD is also believed to affect more women than men [12].…”

Trichotillomania/hair pulling disorder (HPD) and excoriation/skin picking disorder (SPD) are childhood-onset, body-focused repetitive behaviors that are thought to share genetic susceptibility and underlying pathophysiology with obsessive-compulsive disorder (OCD) and Tourette syndrome (TS). We sought to determine the prevalence of DSM-5 HPD and SPD in TS patients, and to identify clinical factors most associated with their co-morbidity with TS. Participants included 811 TS patients recruited from TS specialty clinics for a multi-center genetic study. Patients were assessed using standardized, validated semi-structured interviews. HPD and SPD diagnoses were determined using a validated self-report questionnaire. HPD/SPD prevalence rates were calculated, and clinical predictors were evaluated using regression modeling. 3.8 and 13.0% of TS patients met DSM-5 criteria for HPD and SPD, respectively. In univariable analyses, female sex, OCD, and both tic and obsessive-compulsive symptom severity were among those associated with HPD and/or SPD. In multivariable analyses, only lifetime worst-ever motor tic severity remained significantly associated with HPD. Female sex, co-occurring OCD, ADHD, and motor tic severity remained independently associated with SPD. This is the first study to examine HPD and SPD prevalence in a TS sample using semi-structured diagnostic instruments. The prevalence of HPD and SPD in TS patients, and their association with increased tic severity and co-occurring OCD, suggests that clinicians should screen children with TS and related disorders for HPD/SPD, particularly in females and in those with co-occurring OCD. This study also helps set a foundation for subsequent research regarding HPD/SPD risk factors, pathophysiology, and treatment models.

“…For instance, a prevalence of 5.4% of possible SPD (assessed by means of the SPSQ) was verified in a study that enrolled Israeli Jewish and Arab clinical samples, 38 while prevalence rates of possible SPD were 7.6% and 9.0% among Polish university students and medical students from Karachi (Pakistan) respectively. 6,7 Thus, differences in tools used to assess the presence of possible SPD as well as differences in sample selection and settings across studies could have contributed to these discrepant findings. Furthermore, although not all studies are consistent, accumulating evidence indicates that SPD is more prevalent among women.…”

“…3 The present data add to the small number of studies that have been thus far conducted in low-and middle-income countries. [6][7][8] Our study also explored several clinical correlates associated with SPD with the use of validated self-report instruments, and found that SPD has a detrimental impact on physical and psychological QoL, even when controlling for sociodemographic variables and comorbidity.…”

BackgroundSkin picking disorder (SPD) remains poorly understood with limited data regarding its underlying pathophysiology and appropriate treatment choices. One approach to refining our treatment of SPD might be to better understand the range of illness severity and the clinical associations with severity.Methods125 adults aged 18 to 65 with a primary, current DSM-5 diagnosis of SPD were assessed for the severity of their picking, using the Skin Picking Symptom Assessment Scale, and related mental health symptoms. To identify clinical and demographic measures associated with variation in disease severity, we utilized the statistical technique of partial least squares (PLS).ResultsGreater SPD symptom severity was associated with higher Barratt attentional impulsiveness and motor impulsivity, higher Eysenck impulsivity, higher state anxiety/depression, having a current anxiety disorder, and having a lifetime substance use disorder.ConclusionsThe present analysis is, to our knowledge, the most complete assessment of clinical variables and their relationship to illness severity in a sample of adults with SPD. Aspects of impulsivity and anxiety are both strongly associated with worse illness severity, and functional disability, in SPD. Treatment approaches should incorporate these as possible treatment targets when developing new treatment approaches to this disorder.
