Children may suffer from a wide range of behavioral problems, but children living under conditions of perpetual stress and trauma and experiencing breakdown of family structures are tremendously affected. This study was adopted to identify the prevalence of behavioral disorders among children under parental care and out of parental care.A cross-sectional comparative descriptive study was conducted among 300 children of age 6-12 years from a pediatric outpatient department of a selected hospital and 300 children from selected orphanages in Kolkata to compare the prevalence of behavioral disorders in children under parental care and out of parental care using Strengths and Difficulties Questionnaire (SDQ).Total difficulty was more prevalent in children out of parental care (220 children) than in children under parental care (128 children). Conduct problem was the most prevalent behavioral disorder among all the subscales of SDQ with 48.70% and 84.30% of children, respectively. This was followed by peer problem (44.60% and 48.30%), emotional problem (33.70% and 55.60%), and hyperactivity problem (26.70% and 32.30%), respectively. There was significant difference in total difficulty, all subscales, externalizing score, internalizing score, and impact score between the two groups. Regression analysis showed significant relationship of selected variables such as the child's favorite hobbies and number of close friends the child has using total difficulty score in both the groups. Significant correlation was found among subscales in both the groups.Family-based care and improvised institutional care should be emphasized to reduce the burden of behavioral problem in children.
