Please answer each question by choosing how much you agree with the statement, or how much you think it is true of your son/daughter. Please answer each item, without spending too much time on any one item. There are no right or wrong answers.

Description

The ChOCI-R-P is a 32-item, two-part measure assessing the content and severity of compulsions and obsessions in children and adolescents aged 7-17 years. It is completed by a parent rather than being self-report. Part One of the measure looks at the child’s symptoms of compulsions and impairment associated with compulsions, and Part Two addresses the child’s obsessional symptoms and impairment associated with obsessional symptoms.

Validity and Reliability

Uher, Heyman, Turner and Shafran (2008) evaluated the ChOCI-R-P with a clinical sample of 285 children and adolescents with OCD. The ChOCI-R-P has acceptable internal consistency, and the ChOCI-R-P impairment scales show convergent validity with the similarly-structured CY-BOCS. Scores on the parent version strongly correlated with scores on the self-report version of the measure, at the item and subscale level.

Interpretation

A raw score for each compulsion and obsession subscale is provided as output, along with raw scores for total impairment (range 0-48) and total symptoms (range 0-40). Each subscale and total score are also presented as percentiles based on parents’ responses for a sample of children referred to an OCD clinic (Uher et al., 2008). A percentile of 50 is the average parent reported score for a child with OCD. Higher total impairment scores indicate higher levels of severity/distress related to OCD symptoms, whilst higher total symptoms scores indicate greater complexity and pervasiveness of OCD symptoms. Each subscale is computed as follows: – Compulsion Symptom score: Sum of questions 1 to 10 – Compulsions Impairment score: Sum of questions 14 to 19 – Obsession Symptom score: Sum of questions 20 to 29 – Obsession Impairment score: Sum of questions 33 to 38 – Total symptom score: compulsion symptom score + obsession symptom score – Total impairment score: compulsions severity score + obsession severity score
