Communication is one of the fundamental human abilities, enabling the effective expression of thoughts, emotions, and needs, as well as the establishment of social relationships. Disorders in the areas of communication, language, and speech can significantly affect an individual’s everyday functioning, particularly during childhood, when these abilities are developing intensively. Due to their diversity and complexity, such disorders require precise definition, appropriate classification, and systematic diagnostic assessment. Understanding their prevalence and characteristics in clinical practice is essential for effective planning of speech and language therapy and for the development of professional guidelines.
The present master’s study examined the prevalence of communication, language, and speech disorders in children receiving speech and language therapy in Child and Adolescent Mental Health Centres or Mental Health Dispensaries. Data were provided by seven speech and language therapists, and the final sample included 584 children aged between 2 and 17 years, of whom 66,78% were boys and 33,22% were girls. The average age of the children was 6,03 years. The study was based on a quantitative approach, analysing the prevalence of different disorders, their distribution by sex and age, and the co-occurrence of multiple disorders.
The results showed that speech sound disorders were the most prevalent (74 %), followed by language disorders (22 %) and unspecified disorders (12 %), while other disorders occurred less frequently. At the level of broader categories, speech disorders predominated (76 %), followed by language disorders (23 %) and communication disorders (9 %). The findings also indicated that boys were more frequently included in speech and language therapy and that the structure of disorders changes with age, while no statistically significant differences were found with respect to sex. Co-occurrence of multiple disorders was observed in 13 % of the children.
This master’s study contributes to a better understanding of the prevalence of communication, language, and speech disorders in clinical practice and highlights the importance of a consistent and systematic diagnostic approach. The findings provide an important basis for further research and for the development and improvement of speech and language diagnostics and intervention.
