Abstract

In recent years, there has been a considerable increase in the development of assessment tools for obsessive-compulsive symptomatology in children and adolescents. The Obsessive Compulsive Inventory-Child Version (OCI-CV) is a well-established assessment self-report, with special interest for the assessment of dimensions of Obsessive Compulsive Disorder (OCD). This instrument has shown to be useful for clinical and non-clinical populations in two languages (English and European Spanish). Thus, the aim of this study was to analyze the psychometric properties of the OCI-CV in a Chilean community sample. The sample consisted of 816 children and adolescents with a mean age of 14.54 years (SD = 2.21; range = 10–18 years). Factor structure, internal consistency, test-retest reliability, convergent/divergent validity, and gender/age differences were examined. Confirmatory factor analysis showed a 6-factor structure (Doubting/Checking, Obsessing, Hoarding, Washing, Ordering, and Neutralizing) with one second-order factor. Good estimates of reliability (including internal consistency and test-retest), evidence supporting the validity, and small age and gender differences (higher levels of OCD symptomatology among older participants and women, respectively) are found. The OCI-CV is also an adequate scale for the assessment of obsessions and compulsions in a general population of Chilean children and adolescents.

Highlights

Obsessive-Compulsive Disorder (OCD) became part of a new chapter in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [1], entitled Obsessive Compulsive and Related Disorders
Regarding pediatric OCDspecific measures, and according to Iniesta-Sepúlveda, Rosa-Alcázar, Rosa-Alcázar & Storch [9], the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS) [10] is the gold standard in the assessment of Obsessive Compulsive Disorder (OCD) due to its excellent psychometric properties observed throughout studies, but it is a long clinician-administered instrument with an interview format not useful for community settings, and its self-report format is long for screening purposes
We propose the following hypothesis: 1) the Obsessive Compulsive Inventory-Child Version (OCI-CV) scores will be grouped into the same six-factor structure (Doubting/Checking, Obsessing, Hoarding, Washing, Ordering, Neutralizing) or six factors with one second-order factor as in previous studies; 2) the internal consistency and temporal stability estimates of the OCI-CV scores will be similar to those found in previous works; 3) the association of OCI-CV scores will be higher with OCD measures than with other related constructs; and 4) age and gender differences will be found

Summary

Introduction

Obsessive-Compulsive Disorder (OCD) became part of a new chapter in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [1], entitled Obsessive Compulsive and Related Disorders. Regarding pediatric OCDspecific measures, and according to Iniesta-Sepúlveda, Rosa-Alcázar, Rosa-Alcázar & Storch [9], the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS) [10] is the gold standard in the assessment of OCD due to its excellent psychometric properties observed throughout studies, but it is a long clinician-administered instrument with an interview format not useful for community settings, and its self-report format is long for screening purposes. The Obsessive Compulsive Inventory-Child Version (OCI-CV) [11] is an approaching wellestablished assessment self-report, with special interest for the assessment of the dimensionality of OCD. Other self-reports, such as the Childrens Florida Obsessive-Compulsive Inventory [12], the Child Saving Inventory [13], and the Obsessive Beliefs Questionnaire-Children’s Version [14] are promising assessments for assessing symptoms and the severity of OCD, but they do not assess the obsessive-compulsive dimensionality
