Repetitive behavior is a common symptom in children and is characterised by sameness, rigidity and repetitiveness. These stereotypic and repetitive behaviors are seen in various psychiatric as well as neurological disorders. Till today, the focus of almost all studies was on repetitive behavior in ASD & OCD. The purpose of this study is to bring all the children presenting with repetitive behavior under the same roof, to investigate the patterns of repetitive behaviour in children associated with different childhood disorders and to study the distribution and severity of repetitive behaviors among childhood psychiatric disorders. A Cross-sectional observational study, for the duration of 1 year, was performed on 72 Children (0-12yr) with repetitive behaviour attending the child guidance clinic, who had given consent. Children were screened by using CBCL and diagnosed as per ICD-10 DCR. Severity of repetitive behaviors was assessed using the RBS-R scale & score of different subscale of each disorder were compared. Statistical analysis was done on SPSS version 23. Total 8 types of disorders were included in this study. Stereotyped behavior, Self-injurious behavior more in PDD than OCD, MR &TIC. Compulsive behavior more in OCD than PDD, TIC & MR. Ritualistic behavior, sameness behavior, restricted behavior and total score are more in OCD than tic disorder. Stereotyped behavior more in Tic disorder than OCD. Stereotyped behavior and self-injurious behavior more in MR than OCD. This research contributes to the literature looking at domains or specific groups of repetitive behavior within children with PDD, OCD, TIC and other disorders. As per our knowledge this is the first study in India on repetitive behavior in different childhood disorders.
