AbstractIntroductionObsessive-compulsive disorder (OCD) is a clinically heterogeneous condition characterized by a few consistent, temporally stable symptom dimensions. The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a recently developed instrument that allows patient and clinician ratings of dimension-specific symptom severity, as well as estimates of global symptom severity in patients with OCD.MethodsWe examined the psychometric properties of the DY-BOCS in a sample of 128 European adult patients with OCD.ResultsThe results of the psychometric analyses were overall excellent. The internal consistency across the domains of time, distress and interference for each dimension was high. The subscales of the DY-BOCS were largely independent from one another. The convergent and discriminant validity of the DY-BOCS subscales were adequate. The Global Severity and Interference scales were largely intercorrelated, suggesting that they may be redundant. The level of agreement between self-report and expert ratings was adequate although somewhat lower than in the original validation study.ConclusionThe results of the present study confirm the excellent psychometric properties of the DY-BOCS reported in the original validation study.

Compulsive Disorder

Background: We have established an epidemiological obsessive-compulsive disorder (OCD) cohort in Sweden. Individuals contributed DNA for genotyping and sequencing and also completed a Swedish translation of the Obsessive-Compulsive Inventory-Revised (OCI-R), a self-report questionnaire for assessing the severity and type of symptoms of OCD. This study made use of the OCI-R data to examine the severity and symptom dimensions of OCD as well as comorbidity with other psychiatric disorders. Methods: OCI-R data for 1,134 individuals were available for this study, 1,010 diagnosed with OCD, and 124 diagnosed with chronic tic disorders without OCD used as a comparison group. We first evaluated the psychometric properties of the Swedish translation of the OCI-R. Then, we linked data from the Swedish national registries to access and analyze psychiatric comorbidities of OCD. Results: The Swedish translation of OCI-R demonstrated internal consistency (Cronbach's α = 0.9) and clear agreement with the OCI-R six-factor model. The mean total OCI-R score for females was significantly higher than for males. The most comorbid psychiatric condition to OCD were anxiety disorders (13.6%) and major depression (12%). We observed that individuals with OCD frequently had additional comorbid psychiatric disorders and that the severity of OCD was significantly higher in individuals with at least one additional psychiatric comorbidity compared to individuals with no psychiatric comorbidity. Conclusion: We showed that the Swedish translation of the OCI-R has appropriate psychometric properties. Using an epidemiological framework, we were able to assess the severity and symptom dimensions of OCD and comorbidity with other psychiatric disorders.

The aim of the current study was to analyze psychometric properties of the Short LOI-CV in Spanish community sample. Participants were 914 children and adolescents with mean age of 13.01 years (51.3% males). An EFA yielded a three-factor model representing Obsessions, Compulsions, and Cleanliness dimensions. Both, total score and subscales showed an adequate internal consistency. The Spanish version also exhibited good test-retest reliability and moderate convergent and discriminant validity. The younger participants (from 8 to 10 years) obtained higher means for total score and subscales than older participants (groups 11-13 and 14-18 years). Significant differences related to gender were also observed since males obtained higher means in Compulsions subscale. Despite more research is required, the Spanish version of the Short LOI-CV exhibited promising psychometric results to assess obsessive-compulsive symptoms in community population.

Convergent And Discriminant Validity

This chapter reviews major findings reported in earlier chapters. First, previous findings confirm the existence of specific symptom dimensions that are highly robust and that show strong convergent and discriminant validity. Second, they establish the existence of multiple symptom dimensions within several disorders. Third, they demonstrate that these specific symptom dimensions have differential criterion validity, differential diagnostic specificity, and differential incremental validity. These symptom data can be used to improve various DSM diagnoses, such as major depression and posttraumatic stress disorder. More fundamentally, they provide the basis for a comprehensive symptom-based model of psychopathology. In addition to the IDAS-II, other instruments assess dimensions underlying sleep disorders, eating disorders, schizotypy, personality disorder, and hypochondriasis. These instruments jointly provide broad coverage of the 19 diagnostic classes contained in DSM-5. These measures support movement away from disorder-based models of psychopathology to ones focused on homogeneous symptom dimensions.

ABSTRACTDespite its heterogeneous symptomatology, obsessive-compulsive disorder (OCD) is currently conceptualized as a unitary diagnostic entity. Recent factor-analytic studies have identified several OCD symptom dimensions that are associated with different demographic variables, comorbidity, patterns of genetic transmission, and treatment response. Functional abnormalities in neural systems important for emotion perception, including the orbitofrontal cortex, lateral prefrontal cortex, anterior cingulate gyrus, and limbic regions, have been reported in OCD. In this review, we discuss the extent to which neurobiological markers may distinguish these different symptom dimensions and whether specific symptom dimensions, such as contamination/washing, are associated with abnormalities in emotion and, in particular, disgust, perception in OCD. Also discussed are findings that indicate that anxiety can be induced in healthy volunteers in response to OCD symptom-related material, and that associated increases in activity within neural systems important for emotion perception occur to washing- and hoarding-related material in particular in these subjects. Further examination of neural responses during provocation of different symptom dimensions in OCD patients will help determine the extent to which specific abnormalities in neural systems underlying emotion perception are associated with different symptom dimensions and predict treatment response in OCD.

Background: There has been an increased effort to understand the nature of obsessive-compulsive disorder (OCD) in non-Western cultures. In particular, growing research has examined OCD in China, but there are no comprehensive instruments that measure both OCD severity and heterogeneity for characterizing samples. Aims: A validated, comprehensive measure that could be used in China would provide researchers with a useful instrument for evaluating severity and heterogeneity of OCD in a non-Western culture, allowing researchers to better understand the universal and cultural components that play a role in the nature of OCD. Method: The current investigation presents data on the reliability and validity of a Mandarin translation of the Obsessive-Compulsive Inventory-Revised (CH-OCI) using both a student (n = 1950) and clinical sample (n = 50 patients with OCD; n = 50 patients with anxiety as a comparison group). Results: Results support the factor structure, convergent and discriminant validity, criterion-related validity, test-retest reliability, and internal consistency of the CH-OCI. Conclusions: Validation of the instrument permits researchers and clinicians to measure OCD presentation in Mandarin-speaking samples.

Interoceptive awareness involves several mind–body dimensions and can be evaluated by self-report with the Multidimensional Assessment of Interoceptive Awareness (MAIA), which has been translated and validated in several countries and is being used in research and clinical contexts. This study systematically translated the MAIA with six additional items using a focus group and evaluated its psychometric properties in a respondent sample of 204 Portuguese university students (52% females; M = 21.3, SD = 3.9 years). Based on exploratory factor analysis, we refined the tool into a 33-item version and tested it in a separate sample ( n = 286; 63% females; M = 21.3, SD = 4.7 years). We then conducted confirmatory factor analysis and examined test–retest reliability and convergent and discriminant validity. We confirmed an acceptable model fit for this Portuguese version (MAIA-P) with 33 items and seven scales; it showed good construct validity and acceptable temporal reliability, The MAIA-P appears to be valuable for assessing self-reported interoceptive awareness in Portuguese healthy adults.

Abstract Background Obsessive-compulsive disorder (OCD) is a clinically heterogeneous disorder. Currently, the Obsessive Compulsive Inventory-Child Version (OCI-CV) is the only self-report measure that fully captures this symptom heterogeneity in children and adolescents. The psychometric properties of the OCI-CV are promising but evaluations in large clinical samples are few. Further, no studies have examined whether the measure is valid in both younger and older children with OCD and whether scores on the measure are elevated in youths with OCD compared to youths with other mental disorders. Methods To address these gaps in the literature, we investigated the psychometric properties and validity of a Swedish version of the OCI-CV in a large clinical sample of youth aged 6–18 years with OCD (n = 434), anxiety disorders (n = 84), and chronic tic disorders (n = 45). Results Internal consistency coefficients at the total scale and subscale level were consistent with the English original and in the acceptable range. Confirmatory factor analyses revealed an adequate fit for the original six-factor structure in both younger and older children with OCD. Correlations between total scores on the OCI-CV and the Children’s Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) were small at pre-treatment (r = 0.19) but large at post-treatment (r = 0.62). Youth with OCD scored higher than those with anxiety and chronic tic disorders, and the OCI-CV was sensitive to symptom change for youth undergoing treatment for OCD. Conclusions This Swedish version of the OCI-CV appears to be a valid and reliable measure of the OCD symptom dimensions across age groups and has good clinical utility.

Obsessive-compulsive disorder (OCD), characterized by repetitive thoughts (obsessions) and behaviors (compulsions), is a leading cause of health-related disability in the world. Various kinds of obsessions and compulsions exist and tend to co-occur in dimensions (e.g., doubting/checking, symmetry/ordering, contamination/cleaning). Cognitive-behavioral therapy (CBT) consisting of exposure and response (ritual) prevention (ERP) is arguably the safest and most efficacious treatment for OCD. ERP involves exposing OCD patients to stimuli that provoke obsessions while coaching them to not ritualize. There is increasing evidence to suggest that the specific symptom dimensions of OCD have unique correlates and different responsiveness to ERP. Although many patients respond to ERP, only a subset achieve minimal symptoms. Given the challenges that may arise in ERP treatment of specific OCD dimensions, there has been increasing interest in examining OCD with relationship-related themes that focus on the romantic relationship or partner. In this case report, we present a case of an adult with OCD containing relationship themes and highlight ERP adaptations we utilized to improve his treatment course.

Compulsive Disorder

The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and different versions of the Padua Inventory (PI) are frequently used instruments to measure symptoms of obsessive-compulsive disorder (OCD). However, little is known of how these different versions of the PI compare to each other in their sensitivity to measuring treatment outcome, and there is currently no adequate explanation to account for the weak relationships between self-report measures and the Y-BOCS. This study aimed to investigate the sensitivity of these measures to treatment outcome, and to examine whether differences in how they measure symptom severity can explain the weak relationships. Hypotheses were: (1) the Y-BOCS would be significantly more sensitive to measuring treatment outcome than the PI versions; (2) correlations between the measures would be significantly stronger for change scores as compared to relations measured at a single point in time; (3) weak relationships can be explained by the PI measuring symptom severity based on content and the Y-BOCS measuring symptoms, independent of content. Results showed that the Y-BOCS was significantly more sensitive to measuring treatment outcome than the PI versions, while differences between the questionnaires in which severity is measured can provide a partial account for why weak relations are observed between these measures.

Background: Magical thinking has been proposed to have an aetiological role in obsessive compulsive disorder (OCD). Aims: To address the limitations of existing measures of magical thinking we developed and validated a new 24-item measure of magical thinking, the Illusory Beliefs Inventory (IBI). Method: The validation sample comprised a total of 1194 individuals across two samples recruited via an Internet based survey. Results: Factor analysis identified three subscales representing domains relevant to the construct of magical thinking: Magical Beliefs, Spirituality, and Internal State and Thought Action Fusion. The scale had excellent internal consistency and evidence of convergent and discriminant validity. Evidence of criterion-related concurrent validity confirmed that magical thinking is a cognitive domain associated with OCD and is largely relevant to neutralizing, obsessing and hoarding symptoms. Conclusions: It is important for future studies to extend the evidence of the psychometric properties of the IBI in new populations and to conduct longitudinal studies to examine the aetiological role of magical thinking.
