SUMMARY
Psychosocial development will be disrupted if parents are wrong in educating children. Children experience verbal abuse from caregivers, this is because caregivers want to discipline children, but children do not know their developmental tasks so verbal abuse occurs. Caregivers like to shout when calling children, use harsh words, speak ill of children in public, refer to children as children stupid and naughty. Developments that occur at school age require stimulation to avoid various deviations. This study aims to determine the psychosocial development of school age children before and after the provision of therapeutic group therapy for school age.
