A comparison of three assessment instruments for obsessive-compulsive symptoms.

The psychometric characteristics and relationship among the Leyton Obsessional Inventory, Maudsley Obsessional-Compulsive Inventory, and Yale-Brown Obsessive-Compulsive Scale were examined in a sample of 30 obsessive-compulsive patients diagnosed using a structured interview. The majority of the subscales of the various measures were found to have good internal consistency across gender and the mean scores were similar to those reported in other studies. There were also moderate correlations between several of the measures and clinician ratings of depression. The results suggest that (1) gender differences should be further explored in future research (2) caution should be used when extrapolating the results of treatment studies that use different OCD measures, and (3) a measure of depression should always be included in OCD studies to control for the possible effects of depressed mood.

Maudsley Obsessional-Compulsive Inventory: obsessions and compulsions in a nonclinical sample.

Obsessive-compulsive disorder is increasingly being studied in nonclinical samples. The self-report instruments used to select these samples, however, have not been validated with a diagnostic interview. This study thus investigated the predictive validity of the Maudsley Obsessional-Compulsive Inventory (MOCI) using the Anxiety Disorders Interview Schedule (ADIS), a semi-structured interview created according to DSM-III guidelines. Four sections of the ADIS--generalized anxiety disorder, simple phobia, social phobia and obsessive-compulsive disorder--were administered to 11 individuals who scored in the top 2% and 11 individuals who scored in the normal range of the MOCI 6-7 months prior to the interview. High nonclinical MOCI scorers reported more frequent and severe obsessions and compulsions as well as greater disturbance by these symptoms. In addition, the high MOCI group experienced more general worry and interference from worry, and more frequent and severe physiological symptoms when they worry. However, the two groups did not differ in terms of simple and social phobia symptoms. High MOCI scorers thus did not report a broad range of anxiety symptoms or fears, but specific obsessions and compulsions. These results provide further support for the validity of the MOCI in nonclinical samples over a 6-7 month interval.

Obsessions and compulsions: psychometric properties of the Padua Inventory with an American college population.

The psychometric properties of the Padua inventory, a self-report measure of obsessive-compulsive behaviors, were examined in a sample of 678 American college students. Results showed good internal consistency as well as convergent and divergent validity with the subscales of the Symptom Checklist-90 Revised and the Maudsley Obsessional-Compulsive Inventory. A principal components analysis suggested a four factor solution (i.e. 'impaired control of mental activities', 'checking', 'urges and worries of losing control of motor behaviors', and 'being contaminated'). The factor structure was very similar to that found in the original Italian study of the inventory. Suggestions are made for the use of the Padua Inventory in the study of obsessions and compulsions in nonclinical samples.

The Maudsley Obsessional-Compulsive Inventory: a psychometric investigation on Chinese normal subjects.

The 30-item Maudsley Obsessional-Compulsive Inventory (MOCI) was administered to 183 normal English-speaking Chinese subjects. The inventory achieved modest to relatively low internal consistency as a scale and as four subscales. Three independent dimensions of obsessional complaints interpretable as Perfectionistic and Repetitive Checking, Fear of Contamination, and Doubting Rumination emerged in the factor analysis of item responses. While the first factor corresponded to the Checking component, the second to the Cleaning component, the third was reminiscent of the Doubting, Ruminating and Slowness components. The responses to the MOCI were also explored in their correlations with depression and assertiveness. These results were discussed in in terms of the development of a refined and shortened version of the MOCI and their implications for developing differential treatment models for obsessive-compulsive patients.

Prevalence of DSM-III-R disorders among nonclinical compulsive checkers and noncheckers in a college student sample.

The prevalence of lifetime DSM-III-R disorders was assessed in a sample of 100 college students who were classified as compulsive checkers (n = 50) or noncheckers (n = 50) on the basis of their responses to the Checking subscale of the Maudsley Obsessional-Compulsive Inventory (MOCI). DSM-III-R disorders were assessed on the basis of responses to the Diagnostic Interview Schedule, Version III Revised (DIS-III-R), administered by trained, lay interviewers, blind to Ss' checking status. Checkers, compared to noncheckers, were significantly more likely to meet lifetime diagnostic criteria for Major Depressive Episode, Drug Abuse/Dependence, and Social Phobia. Analysis of a subsample (n = 74) selected on the basis of the consistency of responses to the MOCI across two administrations replicated the above effects, with two exceptions: (1) checkers were more likely to meet criteria for Obsessive Compulsive Disorder than were noncheckers, and (2) for males, but not females, Simple Phobia was more prevalent among checkers than among noncheckers. These findings extend our previous work by demonstrating that 'nonclinical' checking behavior is associated with a broad range of psychological syndromes and may, in fact, be more strongly associated with other disorders than it is with Obsessive Compulsive Disorder in a nonclinical sample.

Worry and obsessional symptoms: a correlational analysis.

Several studies have suggested that worry and obsessional symptoms are systematically associated. In the present study, the relationship between worry and obsessional symptoms was confirmed. Measures included a worry content measure, a worry visual analogue scale, a modification of the everyday checking behaviours scale, and the MOCI. Worry was found to be more consistently associated with checking and doubting, than washing and slowness. It is suggested that worry and obsessional symptoms both occur in response to stress. In addition, it is suggested that worry and checking are functionally similar, and Generalised Anxiety Disorder may represent a 'cognitive' variant of obsessional checking.

Do patients suffering from obsessions alone differ from other obsessive-compulsives?

The aim of this study was to determine whether a group of 48 patients with obsessions and compulsions differed from a group of 26 patients with obsessions alone, on the basis of demographic variables, variables relating to obsessive-compulsive neurosis, psychological variables and treatment outcome. It was found that they differed significantly in the following areas: marital status, level of education, age at onset of complaints, psychoactive medication taken when admitted for treatment, severity of obsessive-compulsive complaints, depression and intelligence. No difference was found as far as treatment outcome was concerned. Patients suffering from obsessions alone, would appear to form a distinct sub-group within the group of obsessive-compulsive patients as a whole.
