Abstrakt: Background: Validated patient-reported outcome measures to assess disease impact in patients with adult idiopathic inflammatory myopathies (IIMs) are needed. The objective of this study was to assess the construct validity of PROMIS Pain Interference, Fatigue, and Physical Function measures in comparison with core disease activity measures.
Methods: Adults with IIM, excluding inclusion body myositis, from OMERACT Myositis Working Group (MWG) clinic sites completed PROMIS Short Form v1.0-Pain Interference 6a, PROMIS Short Form v1.0-Fatigue 7a, and PROMIS Short Form v2.0-Physical Function 8b measures. Core disease activity measures including patient and physician global disease activity assessments, manual muscle testing, serum creatine kinase activity, and Health Assessment Questionnaire Disability Index (HAQ-DI) were simultaneously assessed. To evaluate construct validity, a priori hypotheses for the expected correlations between PROMIS measures, age, and core disease measures were determined by >70 % agreement among MWG members and were compared against observed Pearson's correlations. Internal consistency of items and floor or ceiling effects for the PROMIS measures were also assessed. Subgroup analysis according to IIM subtype (dermatomyositis vs. non-dermatomyositis IIM) was performed.
Results: 135 adults with IIM from 5 countries across North America, Europe, Asia, and Australia were included. For construct validity, a priori hypotheses were confirmed for 5 of 6 (83 %) PROMIS Pain Interference, 4 of 5 (80 %) PROMIS Fatigue, and 3 of 4 (75 %) PROMIS Physical Function correlations. Internal consistency was high for each PROMIS measure (Cronbach's alpha >0.9). Ceiling effects were observed only for PROMIS Pain Interference, with low/no pain in 29 % of patients. Subgroup analysis between dermatomyositis (n = 65) and non-dermatomyositis (n = 70) subtypes demonstrated similar correlations between PROMIS measures and disease activity measures.
Conclusions: PROMIS Short Form v1.0-Pain Interference 6a, PROMIS Short Form v1.0-Fatigue 7a, and PROMIS Short Form v2.0-Physical Function 8b measures demonstrate strong construct validity when compared to core disease activity measures in IIM, with consistent results across IIM subtypes. These findings support the use of these selected PROMIS measures to assess core domains of interest for measuring life impact in IIMs.
