Validity and clinical utility of the obsessive compulsive inventory - child version: further evaluation in clinical samples

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 posttreatment (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.

Efficacy and cost-effectiveness of therapist-guided internet-delivered behaviour therapy for children and adolescents with Tourette syndrome: study protocol for a single-blind randomised controlled trial

“…Depressive symptoms will be measured by the Short Mood and Feelings Questionnaire (child and parent-reported versions; SMFQ-C and SMFQ-P, respectively) [ 45 , 46 ]. OCD symptoms will be measured by the child-reported Obsessive-Compulsive Inventory – Child Version (OCI-CV) [ 47 , 48 ]. The parent-reported Side Effects Questionnaire will be used to record side effects (adverse events) [ 49 ].…”

Online Cognitive Bias Modification of Interpretation for Children With Obsessive-Compulsive Disorder

“…Cronbach's alpha coefficient was estimated to be 0.85 for the whole questionnaire, and between 0.81 and 0.88 for its subscales, which supports the internal consistency of the measure (Foa et al, 2010). Besides internal consistency, structural validity, construct validity, and test-retest reliability of this questionnaire have also been approved in various studies among clinical and non-clinical samples (Aspvall et al, 2020;Jones et al, 2013;Rodríguez-Jiménez et al, 2016). Karimi et al (2015) verified the internal consistency, structural validity, and construct validity of the Persian version of this questionnaire.…”

“…Items are scored from ‘never’ (score 0) to ‘always’ (score 2), with a maximum score of 42. A higher score indicates more severe symptoms [ 28 , 29 ].…”
