Perfectionism and eating disorders: current status and future directions.

The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is the most frequently applied test to assess obsessive compulsive symptoms. We conducted a reliability generalization meta-analysis on the Y-BOCS to estimate the average reliability, examine the variability among the reliability estimates, search for moderators, and propose a predictive model that researchers and clinicians can use to estimate the expected reliability of the Y-BOCS. We included studies where the Y-BOCS was applied to a sample of adults and reliability estimate was reported. Out of the 11,490 references located, 144 studies met the selection criteria. For the total scale, the mean reliability was 0.866 for coefficients alpha, 0.848 for test-retest correlations, and 0.922 for intraclass correlations. The moderator analyses led to a predictive model where the standard deviation of the total test and the target population (clinical vs. nonclinical) explained 38.6% of the total variability among coefficients alpha. Finally, clinical implications of the results are discussed.

There is evidence that religion and other cultural influences are associated with the presentation of obsessive-compulsive symptoms, as well as beliefs and assumptions presumed to underlie the development and maintenance of these symptoms. We sought to further examine the relationship between Protestant religiosity and (1) various symptoms of obsessive-compulsive disorder (OCD) (e.g., checking, washing) and (2) OCD-related cognitions. Using self-report questionnaires, we compared differences in these OCD-related phenomena between highly religious Protestants, moderately religious Protestants, and atheist/agnostic participants drawn from an undergraduate sample. Highly religious versus moderately religious Protestants reported greater obsessional symptoms, compulsive washing, and beliefs about the importance of thoughts. Additionally, the highly religious evinced more obsessional symptoms, compulsive washing, intolerance for uncertainty, need to control thoughts, beliefs about the importance of thoughts, and inflated responsibility, compared to atheists/agnostics. Results are discussed in terms of the relationship between religion and OCD symptoms in the context of the cognitive-behavioral conceptualization of OCD.

Publisher Summary This chapter reviews cross-cultural research on obsessive compulsive disorder (OCD) symptoms and cognitions and present cross-cultural data about cognitive phenomena in OCD Several epidemiological researches disclose differences in OCD prevalence across cultures, and such differences might be considered possible clues regarding cultural influences on this form of psychopathology Epidemiological research also inquired into the demographic variables associated with OCD OCD in adults appears to have an equal gender distribution, although differences have been reported in some symptom categories, such as contamination/washing which may be more prevalent in women Obsessive compulsive patients are less likely to be married than age matched controls Lastly, there is conflicting evidence about the role of intelligence, social class, and birth order Culture provides the categories, explanatory frames, and idioms for responding to physiological symptoms and also plays a significant role in structuring pathologies of cognitions themselves Thus, culture may differently shape beliefs or core cognitive schemas thought to be etiologically relevant to OCD
