Background: Recent evidence suggests that children and adolescents presenting poor motor skills are at greater risk of developing internalizing symptoms, emotional/behavioural and externalizing problems. Motor coordination difficulties, as in Developmental Coordination Disorder, co-occurrence with Attention Deficit/Hyperactivity and Autism Spectrum Disorders are well documented. Few studies investigated the co-occurrence of motor difficulties and mood, anxiety, psychotic and emerging personality disorders in children and adolescents.Objectives: To investigate whether children presenting psychiatric symptomatology manifest motor coordination difficulties.Methods: 48 children and adolescents in semi-hospitalisation in a psychiatric-day facility were selected during a period of two years and screened according to DSM-5 criteria and a motor coordination assessment battery.
