“…The Y-BOCS Total score showed good convergence with most measures commonly used to assess OCS in OCD patients (Goodman et al, 1989b;Storch et al, 2005;Deacon and Abramowitz, 2005), although not with all (Kim et al, 1990(Kim et al, , 1992Woody et al, 1995). Regarding the discriminant validity of the Y-BOCS Total score in samples of OCD patients, a moderate correlation with anxiety and moderate to strong correlations with depression were found (Goodman et al, 1989b;McKay et al, 1995;Woody et al, 1995;Deacon and Abramowitz, 2005). This finding is likely to reflect the distress and debilitation that stem from severe obsessive-compulsive pathology (Woody et al, 1995).…”

a b s t r a c t a r t i c l e i n f oIn the past decade there has been an increasing interest in the levels of obsessive-compulsive symptoms (OCS) found in patients with schizophrenia or related disorders. The widely acknowledged gold standard measure of the severity of OCS is the content-free version of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) (Goodman et al., 1989a,b). However, factor analytic research in patients with obsessive-compulsive disorder (OCD) provided varied results. So far no study has been conducted on the factor structure of the Y-BOCS in patients with schizophrenia. The present study addresses this issue. We administered the Y-BOCS in a sample of 217 patients with schizophrenia or related disorders and comorbid OCS who participated in a multicentre cohort study. We used principal component analysis (PCA) to explore the underlying factor structure. A two-factor solution consistent with the originally proposed scoring structure of the Y-BOCS provided the optimal fit. We also found some support for a three-factor solution consistent with earlier findings by Kim et al. and Moritz et al. (Kim et al., 1994;Moritz et al., 2002). The produced factors showed good reliability and strong correlations with the Y-BOCS Total score. However, the resistance to compulsion item failed to demonstrate adequate correlation to the Total score, a finding consistent with earlier findings in several studies with patients with OCD.

“…Although the distinction between obsessions and compulsions is comfortably established in clinical usage and has been a crucial conceptual starting point for many theoretical discussions and empirical studies (5,13,(36)(37)(38)(39)(40), there is mounting evidence to support a more multidimensional view of obsessive-compulsive disorder (9,10). In this study, an identical set of four symptom dimensions emerged in two separate sets of data.…”

“…Historically, attempts to classify patients with obsessive-compulsive disorder on the basis of their clinical phenotype have met with limited success (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14). Early descriptive efforts yielded a rough topology that lacked a sound empirical basis (4,5).…”

“…As pointed out by Baer and colleagues (9, 10), such biases inherently limit the value of these reports. More problematic is the use of composite severity ratings based on all of the patient's obsessions and compulsions (11)(12)(13). The use of such ratings assumes the unity of the obsessive-compulsive disorder construct and loses the rich diversity of symptoms.…”

“…This approach fails to take into account the changing constellation of symptoms that can be observed over time (14). Finally, many of these studies have relied on data from a relatively small number of subjects (6,9,10,13) that could yield unstable estimates from factor analyses.…”
