The overall psychometric performance of the EA-QOL-questionnaires for EA/TEF children is satisfactory and can enhance outcome evaluations in future research and clinical practice.

Background Achondroplasia is the most common form of disproportionate short stature and might affect not only the quality of life of the affected child but also that of the parents. Objectives We aimed to investigate the quality of life of children with achondroplasia from child- and parent perspective as well as the parental quality of life. Methods Forty-seven children with achondroplasia and 73 parents from a German patient organization participated. We assessed children’s quality of life using the generic Peds QL 4.0™ as self-reports for children aged 8–14 and parent-reports for children aged 4–14 years. Parental quality of life we assessed using the short-form 8-questionnaire. Results Children with achondroplasia showed significantly lower quality of life scores compared to a healthy reference population from both the child- and parent-report (p = ≤.01), except the child-report of the emotional domain ( t (46) = − 1.73, p = .09). Parents reported significantly lower mental health in comparison with a German reference population ( t (72) = 5.64, p ≤ .01) but no lower physical health ( t (72) = .20, p = .85). While the parental quality of life was a significant predictor of parent-reported children’s quality of life ( F (6,66) = 2.80, p = .02), it was not for child-reported children’s quality of life ( F (6,66) = .92, p = .49). Conclusions Achondroplasia is chronically debilitating. Thus special efforts are needed to address patients’ and parent’s quality of life needs. This special health condition may influence the daily life of the entire family because they have to adapt to the child’s particular needs. Therefore, clinicians should not only focus on the child’s quality of life but also those of the parents.

Assessing quality of life (QoL) as a patient-reported outcome in adult psychiatry poses challenges in terms of concepts, methods, and applications in research and practice. This review will outline conceptually the construct of QoL, its dimensionality, and its representation across patient groups. Methodological challenges are examined, along with principles of QoL instrument development and testing, as well as across cultures. Application of instruments in epidemiological, clinical health economics, and health services research is reviewed based on pertinent literature. Validated measures for depression, psychosis, and anxiety disorders are available in adult psychiatry, and are increasingly used in research. Still, targeted measures are lacking for many mental health conditions and only rarely are tools applied in the practice context. Progress has been made in the development of instruments that are now ready for implementation. The information to be gained is valuable for identifying patient-reported needs for and benefits of treatment.
