Children with mental disability show below average intellectual abilities and social behavior adaptability. Living with a disabled child can have profound effects on the entire family–parents, siblings, and extended family members. Meeting the needs of children with disabilities can be challenging for schools and families. However, effective support for children’s mental health and wellbeing involves efforts to meet the social, emotional and learning needs of all children. This study aimed to investigate factors affecting the occurrence of mental disability in children aged 6 to 15 years old.
