Method of administration of PROMIS scales did not significantly impact score level, reliability, or validity

摘要: Abstract Objectives To test the impact of method administration (MOA) on score level, reliability, and validity scales developed in Patient Reported Outcomes Measurement Information System (PROMIS). Study Design Setting Two nonoverlapping parallel forms each containing eight items from three PROMIS item banks (Physical Function, Fatigue, Depression) were completed by 923 adults with chronic obstructive pulmonary disease, depression, or rheumatoid arthritis. In a randomized crossover design, subjects answered one form interactive voice response (IVR) technology, paper questionnaire (PQ), personal digital assistant (PDA), computer (PC) second PC, same administration. Method equivalence was evaluated through analyses difference scores, intraclass correlations (ICCs), convergent/discriminant validity. Results analyses, no significant mode differences found all confidence intervals within prespecified minimal important 0.2 standard deviation. Parallel-forms reliabilities very high (ICC = 0.85–0.93). Only across-mode ICC significantly lower than same-mode ICC. Tests showed differential effect MOA. Participants preferred screen interface over PQ IVR. Conclusion We statistically clinically levels psychometric properties IVR, PQ, PDA compared PC.
