Are parent-reported repetitive and restricted behaviours associated with psychological problems in pre-school-aged children?

Abstract

This study surveys the association of restricted and repetitive behaviours in pre-school children with their emotional and behavioural problems. Parents of 504 pre-school children selected by cluster sampling participated and filled in the questionnaires including repetitive and restricted behaviour (RRB) scale and the Strengths and Difficulties Questionnaire. The parents reported repetitive and restrictive behaviours are gender-related in pre-school-aged children. Hyperactivity and emotional problems are significantly in association with all the four types of repetitive and restrictive behaviours. Prosocial problems score is in association with 'reaction to change' subscale score. Children with higher scores of conduct problems have higher rates of 'sensorimotor stereotypies', 'reaction to change' and 'modulation insufficiency'. Pre-school children with a higher rate of RRBs are more hyperactive and have more emotional problems than those with lower rates of RRBs. Conduct problems are more common in children with 'sensorimotor stereotypies', 'reaction to change' and 'modulation insufficiency' problems. Repetitive and restricted behaviours are associated with mental health problems in pre-school-aged children.
