Resources and Information

It is a semi-structured interview that consists of 10 core items, 5 measuring time, interference, distress, resistance and control of obsessions items: 1—5and 5 identical items measuring compulsions items: 6— External link. Since resistance items have proved to bring unstable factors, analyses of internal consistency were conducted, without these items, to ascertain whether their removal might increase internal consistency.

The best fit was obtained for compulsibe new two-factor structure disturbance: items 2, 3, 7, 8; and symptom yale brown obsessive compulsive scale ybocs items: 1, 4, 5, 6, 9, Kim et al.

In both samples, the best fit was achieved by the three-factor structure: obsessions, compulsions, and resistance. The same study Moritz et al. Furthermore, Moritz et al. Another limitation is that most publications provide limited sample characteristics, making it difficult to compare the samples used.

Since the two-factor solution is the original theory-driven structure, and the most widely used, we recommend the use of this factor.

Scald three-factor structure obsessions, compulsions, and resistance provided the best fit for the data across different factor analytic procedures. These findings suggest that the Yale-Brown Scale is a reliable instrument for measuring the severity of illness in patients with obsessive-compulsive disorder with a range of severity and types of obsessive-compulsive symptoms. Weaknesses include the use of various assessment measures for diagnosis, which might have particularly influenced comorbidity rates. Cognitive behavioral therapy Exposure and response prevention Inference-based therapy Metacognitive therapy.

Contradictory results of these endeavors might explain the more ybocs use of total scores in measuring treatment effects, rather than using the different suggested factors. Confirmatory factor analyses run on the same sample produce identical findings. A non-significant Chi-square value indicates a good fit between a model and the data. In contrast to the rest of the scale, the resistance items items: 4, 9 have demonstrated problematic psychometric properties and lower correlations to the Y-BOCS total scores Goodman et al.

Nevertheless, it is interesting to note that exploratory factor analyses without resistance items produce a two-factor jbocs, without yale brown obsessive compulsive scale ybocs loadings of items. Another interesting finding is that the differences between the goodness of fit of the three-factor model, and the original obsessions-compulsions two-factor model are minimal.

The MINI is a brief structured clinical interview divided into 15 modules The Yale-Brown Obsessive Compulsive Scale was designed to remedy the problems of existing rating scales by providing a specific measure of the severity of symptoms of obsessive-compulsive disorder that is not influenced by the type of obsessions or compulsions present. Furthermore, it would have been desirable to have larger sample sizes, namely in the non-OCD clinical control group, as well as to have a control group without significant differences in demographic characteristics, especially considering the weak positive correlations with age across all psychometric instruments used.

McKay et al. Nevertheless, our study is not free of limitations. This version included the 10 usual items and 2 additional items assessing free intervals from obsessions and compulsions. These findings were consistent with earlier findings of factor structures detected by the confirmatory factor analytic method.

Double loadings were found for items 5 control over obsessionsand 10 control over compulsions. This study was criticized Amir et al. Psychiatry Res. Contradictory results of these endeavors might explain the more common use of total scores in measuring treatment effects, rather than using the different suggested factors. Further, since data was derived from various research projects, no comparison with other OCD measures was available. Since the two-factor solution is the most widely used, and compatible with original theoretical and DSM-IV conceptualizations of OCD, it seems that keeping this model is best advised.
