The prevalence and comorbidity rates of specific learning disorder among primary school children in Turkey.

The aim of the present study was to explore the prevalence of specific learning disorder (SLD), comorbid disorders, and risk factors in primary school children for the first time in two-stage design in Turkey. Participants were 1041 pupils in 28 primary schools and aged from 7 to 11. The Mathematics, Reading, Writing Assessment Scale (MOYA) teacher and parent forms were used in the screening stage and parents and teachers of each child completed MOYA. Ninety-five children were screen positive and eighty-three of these children participated in the interview. SLD diagnoses were based on DSM V criteria. Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL) was used for the comorbid psychiatric disorders. The prevalence rate of the SLD was 6.6%, impairment in reading was 4%, in mathematics was 3.6%, and in written expression was 1.8%. About 62.75% of children with SLD had one or more comorbid diagnoses. ADHD was the most common comorbid mental disorder in SLD (54.9%). The prevalence of SLD in primary school children in Turkey is similar with previous studies.
