Psychometric Properties of the Obsessive Compulsive Inventory: Child Version in Children and Adolescents with Obsessive–Compulsive Disorder

Abstract

The psychometric properties of the Obsessive Compulsive Inventory-Child Version (OCI-CV) were examined in ninety-six youth with a primary/co-primary diagnosis of obsessive-compulsive disorder (OCD). A confirmatory factor analysis revealed an acceptable model of fit with factors consisting of doubting/checking, obsessing, hoarding, washing, ordering, and neutralizing. The internal consistency of the OCI-CV total score was good, while internal consistency for subscale scores ranged from poor to good. The OCI-CV was modestly correlated with obsessive-compulsive symptom severity on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) Severity Scale, as well as with clinician-reported OCD severity. All OCI-CV subscales significantly correlated with the corresponding CY-BOCS Symptom Checklist dimension. The OCI-CV significantly correlated with child-reported depressive symptoms and OCD-related functional impairment, but was not significantly correlated with parent-reported irritability or clinician-reported overall functioning. Taken together, these data suggest the psychometric properties of the OCI-CV are adequate for assessing obsessive-compulsive symptom presence among youth with OCD.

Evidence-Based Assessment of Obsessive–Compulsive Disorder

“…Convergent validity is fair to poor as evidence by significant correlations with clinician-rated measures of OCD severity. Additionally, the OCI-CV total score has fair to good discriminant validity with measures of irritability and depression 98,99. The OCI-CV has demonstrated treatment sensitivity to medication and CBT 71.…”

Obsessive–Compulsive Personality Traits in Youth with Obsessive–Compulsive Disorder

“…The OCI-CV provides a composite score as well as scores for the following factorially derived subscales: hoarding, neutralizing, obsessions, washing, ordering, doubting, and checking. The OCI-CV total score and subscale scores have demonstrated strong internal consistency, test-retest reliability, and treatment sensitivity [22,23]. Internal consistency for the OCI-CV was excellent for the present sample (a = 0.92).…”

Developing and Evaluating the Effectiveness of the Behavioral-Cognitive-Metacognitive Intervention on the Severity of Obsessive- Compulsive Disorder’s Symptoms

“…In general, the score range of the revised form of the questionnaire is from 0 to 72 in which higher scores indicate the intensity of symptoms. A good internal consistency (α = 0.80 -0.88) and acceptable test-retest reliability (r = 0.67 -0.70) in a nonclinical sample for the revised obsessive-compulsive inventory have been obtained [14] [15]. Convergent validity supports the OCI-R and represents a high correlation between the questionnaire and other obsessive-compulsive scales [15].…”

Convergent validity supports the OCI-R and represents a high correlation between the questionnaire and other obsessive-compulsive scales [15]. Discriminant validity also supports the OCI-R and indicates that the scale is able to discriminate OCD sufferers from other patients [16] [17].…”
