The aim of this publication is to present the impact of auditory processing disorder (APD) on a child's daily functioning, with a particular focus on the emotional and social sphere and the assessment of quality of life (HRQL – Health Related Quality of Life). The case study illustrates the real-life challenges faced by a child with APD and enables the identification of effective therapeutic and educational support strategies. The author conducted an analysis of data regarding the functioning of a child with APD in various areas of life (with particular focus on emotional and social aspects) in relation to the assessment of the child's quality of life. The data were obtained through a comprehensive speech and language assessment, observation, the SAB (Scale of Auditory Behaviors) questionnaire completed by the child's parent, and the KIDSCREEN-27 questionnaire in both the parent and child versions. The data were obtained through a comprehensive speech-language assessment, observational methods, and a SAB questionnaire (Scale of Auditory Behaviors) completed by the child’s parent. Additionally, interviews with both the parent and the child were conducted, alongside an analysis of relevant medical and specialist documentation. The study highlights the complexity of problems experienced by a child with APD and their negative impact on overall quality of life. The article concludes with a set of recommendations proposed by the author, developed on the basis of a detailed analysis of the individual case.
