The PedsQLTM 3.0 DM measures the health-related quality of life (HrQoL) specific to diabetes. Even though there is no translation to Ethiopian Amharic, the instruments had translated to different languages and validated. The study is aimed to assess the validity and reliability of the Amharic version of the PedsQLTM 4.0 GCS and the PedsQLTM 3.0 DM in children and adolescents with diabetes.Methods: PedsQLTM 4.0 GCS and the PedsQLTM 3.0 DM were administered on 193 children and adolescents with diabetes and their parents. The validity was examined by the exploratory factor analysis, multitrait/multi-item scaling analysis, and multitrait-multimethod and monotrait-multimethod analysis. Cronbach’s alpha coefficient checked the reliability.Results: Cronbach’s alpha coefficient for the total PedsQLTM 4.0 GCS (α child self-report= 0.96; α parent proxy report= 0.95) and for total PedsQLTM 3.0 DM (α child self-report= 0.96; α parent proxy report=0.93) were acceptable at individual patient-level analysis. The monotrait-multimethod correlations were higher than multitrait-multimethod correlations. In multitrait/multi-item scale analysis, both total PedsQLTM 4.0 GCS and PedsQLTM 3.0 DM had an excellent item convergent and discriminatory validity success rate.Conclusion: The Amharic versions of the PedsQLTM 4.0 GCS and the PedsQLTM 3.0 DM were valid and reliable instruments to measure the HrQoL of children and adolescents with diabetes.Keywords: quality of life, PedsQL™ 3.0 DM, PedsQLTM 4.0 GCS, validation, reliability |
