A cross-sectional comparison of routinized and compulsive-like behaviours in typical children aged from 2 to 11 years

Routinized and compulsive like behaviours (RCBs) have been described as important aspects of development seen universally in children, yet investigation is relatively scarce. One exception was the development of the Childhood Routines Inventory (CRI), which has prompted recent studies. The present study was a replication of the standardization for the CRI on a British sample and with an extended age range. It also explored possible associations with obsessive-compulsive disorder (OCD). The parents of 1,369 children (aged 2–11 years) completed the CRI, and an 8-item OCD scale for those 7 years and over. Socioeconomic status (SES) was measured by proxy post codes; 111 parents completed the questionnaire twice. The CRI had good internal consistency and test–retest reliability. There was a significant linear decline in RCBs with age; a minority of children continued to have high levels up to 11 years of age. Children designated at risk for OCD had higher CRI scores. Anxious behaviours reported by parents of c...
