Introduction: Obsessive-compulsive disorders (OCD) are common mental disorders, whichespecially without treatmentmay take a chronic course. Although they often remain undetected, there is a lack of short and valid screening instruments. With the Dimensional Obsessive-Compulsive Scale-Short Form (DOCS-SF) a screening instrument is available in Norwegian. The aims of the current analogue study were to develop and to validate English and German versions of the DOCS-SF. Methods: In the online surveys, 304 German and 187 English-speaking students participated. In addition to the DOCS-SF, they answered a battery of established questionnaires on OCD, depression and anxiety. For determining retest reliability, 51 German students participated in another survey. Results: Results confirmed the single factor structure of the DOCS-SF and indicated good internal consistency (α = 0.89) as well as retest reliability (r = 0.75). Concerning convergent validity, the DOCS-SF was strongly correlated with other OCD scales. Although correlations with anxiety were strong as well, correlations with measures of depression, health anxiety, disgust, and health-related well-being were significantly weaker. Discussion: The DOCS-SF appears to be a short, reliable, and valid screening instrument for OCD. Subsequent studies should further investigate its divergent validity, and its diagnostic accuracy in clinical populations.

The OCI-R is a psychometrically sound and valid self-report scale measuring the major symptoms of OCD on six dimensions: Checking, Washing, Ordering, Hoarding, Obsessing, and Neutralizing. Information is needed on its ability to discriminate OCD from depression. In this study, reliability and convergent, divergent, and known-groups validity of an authorized German version were examined in 381 patients with OCD, other anxiety and depressive disorders. Confirmatory factor analyses replicated the original six-factor structure in each sample. Moreover, results indicated good convergent, divergent, and known-groups validity for the full scale and the subscales in each sample, only a slight construct overlap between OCD and depression, anxiety, pathological worry, and perfectionism, and the relationships of the subscales with obsessive-compulsive personality features supported its construct validity. Previous findings for the original scale were replicated and extended in a different cultural context. However, the domains Neutralizing and Obsessions need further development. #

In the present study, the psychometric properties of the Obsessive Compulsive Inventory-Revised (OCI-R) (Foa, et al., 2002) were investigated. The OCI-R was administered to a total of 816 Icelandic college students. The Maudsley Obsessive Compulsive Inventory (MOCI) and the Penn State Worry Questionnaire (PSWQ) were administered to a subsample of 304 students, and the PI-WSUR (Padua Inventory Washington State University Revision), the PSWQ and the Multidimensional Perfectionism Scale (MPS) to another subsample of 212 students. Also, 89 students filled in the OCI-R twice with two weeks in between. The factor structure of the instrument was replicated in a confirmatory factor analysis. Cronbach's alpha and test-retest reliabilities of the OCI-R total scale and all subscales were satisfactory. Further, the OCI-R total score showed a significantly higher correlation with the PI-WSUR and the MOCI than with the PSWQ or the MPS. Finally, conceptually similar scales of the OCI-R and the MOCI as well as the PI-WSUR showed higher inter-correlations than the correlations that were observed between conceptually more distinct scales. It is concluded that the Icelandic version of the OCI-R has strong psychometric properties in a student population.
The Dimensional Obsessive-Compulsive Scale: Development and Validation of a Short Form (DOCS-SF)
Frontiers in Psychology
Accurately and reliably measuring the presence and severity of Obsessive-Compulsive Disorder (OCD) symptoms is essential for both routine clinical work and research. The current study investigated psychometric properties of the dimensional obsessive-compulsive scale-short form (DOCS-SF). DOCS-SF was developed and validated in Norwegian. DOCS-SF contains a checklist with four symptom categories and five severity items scored on a zero to eight scale yielding a total score of 0-40. Data were collected from adults with a current diagnosis of OCD (n = 204) and a community comparison group (n = 211). The results provided evidence of internal consistency and convergent validity, although evidence for discriminant validity was mixed. Evidence was also found for diagnostic sensitivity and specificity, and treatment sensitivity. The analyses suggested a cutoff score of 16. In summary, the data obtained proved similar to studies published on the original dimensional obsessive-compulsive scale. There is strong evidence for the reliability and validity of the DOCS-SF for assessing OCD symptoms in individuals with this condition and in non-clinical individuals.

Obsessive-Compulsive Inventory-Revised (OCI-R) is a self-report questionnaire that assesses the distress caused by a variety of OCD symptoms; OCI-R comprises of 18 items that are equally divided into six subscales: Checking, Washing, Obsessing, Neutralization, Ordering, and Hoarding. Research so far has shown that OCI-R is a psychometrically sound measure with excellent validity and reliability. It is also appropriate for clinical and non-clinical populations and has been translated into several languages and has been validated in diverse cultural contexts. The aim of the present study was to validate OCI-R in the Greek language and to examine its psychometric properties in a Greek non-clinical sample. Three hundred and seventy one university students participated in this study. Measures used were OCI-R, the Padua Inventory (PI), the Obsessive Beliefs Questionnaire-44 (OBQ-44), and the Depression Anxiety Stress Scale (DASS-21). Consequent analysis of collected data examined the factor structure of OCI-R and tested its convergent and divergent validity. The confirmatory factor analysis showed good fit for the model and replicated the results of other studies, meeting thus the requirements for the six-factor solution of the original scale. The Greek version of OCI-R maintained the good psychometric properties of the original English one. Internal consistency was excellent for the overall scale. Convergent and divergent validity was good and also confirmed previous similar findings.
The Maudsley Obsessional-Compulsive Inventory and OCD in a Norwegian nonclinical sample
Scandinavian Journal of Psychology, 2000
The 30 item Maudsley Obsessional-Compulsive Inventory (MOCI) was given to 294 under graduate students. The inventory achieved an acceptable internal consistence, but somewhat low reliability. There were no sex difference in total MOCI score, or in any of the subscales. 31% of the variance seemed to be explained by item 18:``attending too much to details'', and more than 65% of the variance is explained by the checking subscale. The data give some interesting indications of the prevalence of OCD in the population.
Revue Européenne de Psychologie Appliquée/European Review of Applied Psychology, 2006
presented a new instrument, the Obsessive-Compulsive Inventory-Revised (OCI-R), designed to evaluate the severity of obsessive-compulsive symptoms in both clinical and non-clinical individuals. The present study investigates the psychometric properties of a French version of this scale. The OCI-R French version was completed by 583 undergraduate students. The results revealed satisfactory internal consistency as measured by Cronbach's alpha coefficients (ranging from 0.63 to 0.86). In addition, the six-factor structure found by was confirmed in our sample by a confirmatory factor analysis. In brief, the French version of the OCI-R seems satisfactory for measuring Obsessive-Compulsive Disorders (OCD) symptoms in non-clinical samples. Future research is, however, needed to confirm these data in a sample of OCD patients.
The validation of a new obsessive-compulsive disorder scale: The Obsessive-Compulsive Inventory
Psychological Assessment, 1998
The Obsessive-Compulsive Inventory (OCI) is a new self-report instrument developed to address the problems inherent in available instruments for determining the diagnosis and severity of obsessivecompulsive disorder (OCD). The OCI consists of 42 items composing 7 subscales: Washing, Checking, Doubting, Ordering, Obsessing (i.e., having obsessional thoughts). Hoarding, and Mental Neutralizing. Each item is rated on a 5-point (0-4) Likert scale of symptom frequency and associated distress. One hundred and forty-seven individuals diagnosed with OCD; 58 with generalized social phobia; 44 with posttraumatic stress disorder; and 194 nonpatients completed the OCI and other measures of OCD, anxiety, and depression. The present article describes the psychometrics of the OCI including (a) scale construction and content validity, (b) reliability (internal consistency and retest reliability), and (c) convergent and discriminant validity. The OCI exhibited satisfactory reliability and validity with all 4 samples.
