ABSTRACT
Developmental coordination disorder (DCD) is one of the most frequently observed movement disorders in childhood, yet data on its prevalence are still unclear. This two-stage epidemiological study aims to determine the prevalence of DCD in children between 6 and 10 years of age according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). In the first stage, the Developmental Coordination Disorder Questionnaire (DCDQ'07) were given to primary school students. In the second stage, clinicians conducted psychiatric interviews with children who had an indication of DCD or were suspected of having DCD according to the DCDQ'07 and their parents. The interviews utilized the DSM-5 diagnostic criteria for DCD and applied the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version-Turkish Adaptation (K-SADS-PL) and Wechsler Intelligence Scale for Children (WISC-R) to identify co-occurring disorders. In the first stage, 2,306 children were evaluated, and 205 were invited for a clinical interview. Of the 198 children interviewed, 49 met the diagnostic criteria for DCD. The prevalence of DCD in Türkiye was found to be 2.1%. High parental education level, a previous psychiatric admission of the child, mother's postpartum depressive symptoms, co-occurring disorders, and co-occurring attention deficit hyperactivity disorder (ADHD) were significantly more common among children with DCD. Potentially associated factors were evaluated by logistic regression analysis. The mother's education level, the presence of postpartum depressive symptoms, and co-occurring disorders in the child were found to be associated factors.
ABSTRACT
A remarkable number of children all over the world have psychiatric disorders, which cause severe impairments in functionality. In the development of future mental health planning, not only determining epidemiological data is sufficient, but also follow-up studies are needed. This study aimed to determine the course of subthreshold psychiatric disorders in three-year follow-up process, and whether there is a relationship between sociodemographic factors, parental attitudes and SDQ scores and the escalating escalation from SPD to psychopathology or the disappearance of SPD symptoms. This study included fifty-four children with age of 7-9 years. The Development and Well Being Assessment, structured diagnostic interview, was used to evaluate psychiatric disorders. Besides, parents were asked to fill out a socio-demographic form and the Parent Attitude Research Instrument. The mean age of children was 8.2 ± 0.8 years, and 59.3% of them were girls, and 40.7% of them were boys. At the beginning of the study, most common subthreshold psychiatric disorders were Specific Phobia with a prevalence of 3%, followed by Attention Deficit Hyperactivity Disorder 2.2%. After three-year of the follow-up period, 37% of subthreshold cases progress into psychiatric disorders. Living in a city centre in a slum and psychiatric disorder history of the family were independent risk factors for developing psychopathology. Living in a village was an effective protective factor in the disappearance of Subthreshold Psychiatric Disorder symptoms. In this study, besides the factors that may be effective in the development of psychiatric disorders, the factors that may be effective in the disappearance of Subthreshold Psychiatric Disorder symptoms were examined.
