Introduction

Achondroplasia is the most common skeletal dysplasia condition, characterized by disproportionate short stature and delayed motor development. Additional potential complications include bowed legs and hypotonia, otitis media, sleep apnea, and complications from spinal stenosis, which may impose potential burden on individuals with achondroplasia, as well as their families. No reliable, validated, and publicly available achondroplasia-specific clinical outcome assessment (COA) is currently available that can capture the experiences of children and adolescents with achondroplasia. We sought to determine whether existing COA measures have adequate concept coverage for use in clinical studies and understand the challenges for children/adolescents with achondroplasia and their parents through concept elicitation and cognitive debriefing interviews.

Methods

Children/adolescents with achondroplasia and parents of children with achondroplasia participated in combined concept elicitation and cognitive debriefing interviews. Issues raised by participants were mapped to four COA measures to evaluate their clarity, relevance, and appropriateness for use in achondroplasia studies.

Results

Eight children/adolescents (aged 11–16) and 18 parents were interviewed. The challenges most often reported by children/adolescents were feeling hot/sweaty (88%), pain (88%), balance issues or falls (75%), fatigue (63%), muscle fatigue/loose joints (63%), and speech issues (63%). Pain (83%), ear infections (78%), and feeling hot/sweaty (78%) were frequently reported by parents. Difficulty reaching things (88%), running (88%), and walking (75%) were the functional challenges most reported by children/adolescents, while parents most commonly reported difficulty reaching things (78%), toileting (63%), bathing (56%), walking (56%), running (56%), and dressing (50%). Results of response mapping indicated that the QoLISSY, PedsQL, WeeFIM, and Pain-NRS cover most of the important concepts mentioned by parents and children/adolescents.

Conclusions

The PedsQL, QoLISSY, Pain-NRS, and WeeFIM are content valid, appropriate, and relevant to include in future studies of individuals with achondroplasia.
