“…The present study provides preliminary evidence to suggest that paper‐and‐pencil and online administrations of the SPD‐D can be used interchangeably, as strong correlations were found between these two forms of administration. This finding is consistent with other studies that have shown equivalence across paper‐and‐pencil and online administration formats when measuring OCRDs using a similar methodology (Carey, del Pozo de Bolger, & Wootton, 2019; Cheyne, Del Pozo de Bolger, & Wootton, 2018; Macfarlane et al, 2019).…”

“…Third, the low response rate for Part 2 of the study indicates that the present results may be biased towards individuals who were more invested in completing the study. Although this attrition is consistent with studies using a similar methodology (e.g., Carey et al, 2019; Cheyne, Del Pozo De Bolger, & Wootton, 2018), participants in Part 2 of the study may comprise of a different sample compared with those who only completed Part 1, and indeed those who completed both parts of the study had significantly higher scores on SPD measures than those who only completed Time 1. Therefore, future studies may wish to reimburse participants in order to retain a higher number of participants at Time 2.…”

Objective The Excoriation (skin‐picking disorder) dimensional scale (SPD‐D) is a new measure of excoriation skin picking disorder (SPD). The 5‐item scale was developed by the Diagnostic and Statistical Manual (Fifth Edition) obsessive–compulsive spectrum disorders sub‐workgroup to assist in the dimensional assessment of SPD. Method The aim of the present study was to provide a psychometric evaluation of this new scale in a large community sample. 803 participants were recruited from online community noticeboards around Australia. Results The results indicated that the SPD‐D demonstrated a unidimensional structure, high internal consistency (rs = .87, .86, and .92 across three samples), and good test–retest reliability (rs = .86). The SPD‐D also demonstrated good convergent validity with the Skin‐Picking Scale Revised (rs = .90) as well as divergent validity with the generalised anxiety disorder scale (rs = .40). Conclusions Overall, the SPD‐D appears to be a brief and reliable measure of SPD symptomatology.

“…Our findings contribute to the development of a CHB instrument by expanding the reliability and validity of the original English-language HRS-I for the assessment of CHB in a general population. Our CFA analysis proposed a five-item, one-factor structure for the CHRS, which is consistent with the DSM-5 and the other hoarding measurement [1,7].…”

Adaptation and psychometric testing of the hoarding rating scale (HRS): a self-administered screening scale for epidemiological study in Chinese population

Background: Hoarding disorder is a chronic and debilitating illness associated with restrictions on activities of daily living, compromised social and occupational functioning, and adverse health outcomes. However, researchers lack a brief and self-administered screening measurement to assess compulsive hoarding in the Chinese speaking population. This study aimed to adapt and validate the Hoarding Rating Scale-Interview (HRS-I) to as a tool for screening compulsive hoarding behavior in Chinese population. Methods: This study comprised two phases. During Phase 1, the English-language HRS-I was translated into Chinese (CHRS) (comprehensible for most Chinese speaking population, e.g., Cantonese & Mandarin) and subjected to an equivalence check. In Phase 2, the CHRS was validated by examining internal consistency, stability, and construct validity. Different samples were used appropriately to verify the items and reflect the psychometric properties. Results: In Phase 1, the CHRS yielded satisfactory content (S-CVI = 0.93) and face validity ratings (comprehensibility = 100%, N = 20 participants of general public with age 18-72) and the English and Chinese versions were found to be equivalent (ICC = 0.887; N = 60 university staff and students). Phase 2 revealed satisfactory levels of internal consistency (Cronbach's α = 0.86; corrected item-total correlation = 0.60-0.74; N = 820 participants of general public), 2-week test-retest reliability (ICC = 0.78; N = 60 university students), and construct validity (onefactor CFA solution matched with the hypothesized model, χ 2 /d.f. = 2.26, RMSEA = 0.049, CFI = 0.99, IFI = 0.99, NFI = 0.99; n = 520 participants of general public). Conclusions: This study provides sufficient evidence of the reliability and validity of the CHRS for compulsive hoarding behavior screening in the Chinese population through self-administered method.

“…Thus, higher score indicates greater severity (possible range = 0-20). Previous studies have shown that the scales have good psychometric properties (Carey, del Pozo de Bolger, & Wootton, 2019;Cheyne, del Pozo de Bolger, & Wootton, 2018;LeBeau et al, 2013;Moreno-Amador, Piqueras, Rodriguez-Jimenez, Marzo, & Mataix-Cols, 2018;Storch et al, 2007).…”

Transdiagnostic dimensions in obsessive-compulsive and related disorders: associations with internalizing and externalizing symptoms

et al. 2020

Background Hierarchical structural models of psychopathology rarely extend to obsessive-compulsive spectrum disorders. The current study sought to examine the higher-order structure of the obsessive-compulsive and related disorders (OCRDs) in DSM-5: obsessive-compulsive disorder (OCD), hoarding disorder (HD), body dysmorphic disorder (BDD), trichotillomania (hair-pulling disorder; HPD) and excoriation (skin-picking) disorder (SPD). Methods Adult patients in a partial hospital program (N = 532) completed a dimensional measure of the five OCRDs. We used confirmatory factor analysis to identify the optimal model of the comorbidity structure. We then examined the associations between the transdiagnostic factors and internalizing and externalizing symptoms (i.e. depression, generalized anxiety, neuroticism, and drug/alcohol cravings). Results The best fitting model included two correlated higher-order factors: an obsessions-compulsions (OC) factor (OCD, BDD, and HD), and a body-focused repetitive behavior (BFRB) factor (HPD and SPD). The OC factor, not the BFRB factor, had unique associations with internalizing symptoms (standardized effects = 0.42–0.66) and the BFRB factor, not the OC factor, had small marginally significant unique association with drug/alcohol cravings (standardized effect = 0.22, p = 0.088). Conclusions The results mirror findings from twin research and indicate that OCD, BDD, and HD share liability that is significantly associated with internalizing symptoms, but this liability may be relatively less important for BFRBs. Further research is needed to better examine the associations between BFRBs and addictive disorders.
