“…While McKay et al (2006) was likely underpowered (n = 137), Stewart et al (2007) (n = 231) still derived somewhat different factors than previous adult category-level analyses, including a factor in which contamination/cleaning loaded with the aggressive and somatic categories. Despite similarities to adult cluster analyses of OCD symptoms (Calamari et al, 1999(Calamari et al, , 2004, Ivarsson and Valderhaug (2006) (n = 213) noted important differences in their child/adolescent cluster analysis such as the absence of subgroups for hoarding and symmetry/ordering. The authors speculated that these discrepancies might be due to developmental differences in OCD phenomenology and clinical course in children/adolescents as compared with adults (Jaisoorya et al, 2003;Stewart et al, 2004).…”

Despite progress in identifying homogeneous subphenotypes of obsessive compulsive disorder (OCD) through factor analysis of the Yale-Brown Obsessive Compulsive Scale Symptom Checklist (YBOCS-SC), prior solutions have been limited by a reliance on presupposed symptom categories rather than discrete symptoms.

The purpose of this study was to extend prior work by this collaborative group in category-based dimensions by conducting the first-ever exploratory dichotomous factor analysis using individual OCD symptoms, comparing these results to a refined category-level solution, and testing the familiality of derived factors. Participants were 485 adults in the six-site OCD Collaborative Genetics Study, diagnosed with lifetime OCD using semi-structured interviews. YBOCS-SC data were factor analyzed at both the individual item and symptom category levels. Factor score intraclass correlations were calculated using a subsample of 145 independent affected sib pairs. The item-and category-level factor analyses yielded nearly identical 5-factor solutions. While significant sib-sib associations were found for 4 of the 5 factors, Hoarding and Taboo Thoughts were the most robustly familial (r ICC ≥ 0.2). This report presents considerable converging evidence for a 5-factor structural model of OCD symptoms, including separate factor analyses employing individual symptoms and symptom categories, as well as sibling concordance.The results support investigation of this multidimensional model in OCD genetic linkage studies.

“…Furthermore, the fact that many patients with compulsive hoarding report little distress or recognition of the problem contrasts with the typical clinical presentation of OCD (therefore, hoarding diagnoses are frequently based on obvious impairment, rather than self-reported distress). Factor and cluster analyses indicate that hoarding consistently emerges as a distinct symptom type, although in two studies hoarding combined with symmetry/ordering to form a separate subgroup (see Calamari et al, 2004, for a review). Although various OCD symptoms appear closely related to one another, hoarding does not appear particularly closely associated with OCD and is just as closely associated with depression as it is with OCD (Wu & Watson, 2005).…”

The aim of the present study was to provide preliminary data on the efficacy of a new cognitivebehavioral treatment (CBT) for compulsive hoarding. Fourteen adults with compulsive hoarding (10 treatment completers) were seen in two specialty CBT clinics. Participants were included if they met research criteria for compulsive hoarding according to a semistructured interview, were age 18 or above, considered hoarding their main psychiatric problem, and were not receiving mental health treatment. Patients received 26 individual sessions of CBT, including frequent home visits, over a 7-12 month period between December 2003-February 2005. Primary outcome measures were the Saving Inventory-Revised (SI-R), Clutter Image Rating (CIR), and Clinician's Global Impression (CGI). Significant decreases from pre-to post-treatment were noted on the SI-R and CIR, but not the CGI-severity rating. CGI-Improvement ratings indicated that at mid-treatment, 40% (n = 4) of treatment completers were rated "much improved" or "very much improved;" at post-treatment, 50% (n = 5) received this rating. Adherence to homework assignments was strongly related to symptom improvement. CBT with specialized components to address problems with motivation, organizing, acquiring and removing clutter appears to be a promising intervention for compulsive hoarding, a condition traditionally thought to be resistant to treatment.

“…In the fourth and last stage, VOCI-MC and TAF-CS were added in the model. Addition of these two measures in the model caused a 2% of increase in the variance, and explained variance was increased to 58% (ΔF [2,238]=4.95, p<0.05). In the last stage, only VOCI-MC predicted significantly OCD symptoms (β=0.14, t=2.44, pr=0.16, p<0.05).…”

“…In the second stage, TAF-Likelihood and TAF-Moral subscales which were among OCD beliefs were included in the model. These variables caused 21% and 30% of increases in the explained variance, respectively (ΔF [2,241]=37.01, p<0.001). When it was investigated which variable caused significant change, it was found that only TAF-Moral dimension significantly predicted OCD symptoms (β=0.46, t=4.12, pr=0.26, p<0.001).…”

The relationship between obsessive compulsive disorder and mental contamination (MC): psychometric properties of Vancouver Obsessive Compulsive Inventory-MC Scale and ThoughtAction Fusion-Contamination ScaleObjective: Mental contamination is defined as feelings of internal dirtiness in absence of actual contact with a dirty physical object or a person. Mental contamination is considered to play an important role in maintenance and persistence of obsessive compulsive disorder (OCD). This study aimed to examine psychometric properties of the Turkish version of two objective measures of mental contamination: Vancouver Obsessive Compulsive Inventory-Mental Contamination Scale (VOCI-MC) and Thought-Action Fusion-Contamination Scale (TAF-CS). Method: The participants were 255 university students (183 females and 70 males) with the age range of 18-28 years. The participants were asked to fill out the questionnaire set consisted of VOCI-MC, TAF-CS, Thought-Action Fusion Scale (TAFS), Disgust Scale-Revised, Trait Anger Expression Inventory and Obsessive Compulsive Inventory-Revised (OCI-R). Results: Reliability analyses indicated that internal consistency of VOCI-MC and TAF-CS were 0.93 and 0.92, and test-retest reliabilities were 0.79 and 0.61, respectively. Consistent with the original study, the results of explanatory and confirmatory factor analysis indicated that both scales had one factor structure. Convergent and divergent validity analyses revealed that both scales were positively correlated with OCI-R total scores and its subscales as well as TAF total score and its subscales; but this relationship was significantly less strong for Trait Anger and Disgust Sensitivity. While VOCI-MC significantly predicted OCD symptomatology, TAF-CS had no predictive power in this regard. Conclusions:The results support that psychometric properties of the Turkish versions of the scales meet acceptable standards for validity and reliability, and therefore can be used among Turkish population.
