A final Delphi panel eliminated one item to avoid redundancy.ConclusionsThe final 27- item self- administered NoMoFA is a valid and reliable questionnaire, capturing both static and fluctuating non- motor symptoms in PD. Concurrent validity was adequate with all Spearman’s rho values comparing NoMoFA score to other measures of parkinsonian severity showing significance and in the expected direction. Test- retest reliability was acceptable (intraclass correlation coefficient Â 0.73 95% confidence interval, 0.64- 0.80). While eight items had - item- to- total- correlations below the cutoff of 0.4, removing these items did not improve Cronbach’s alpha. Classical test theory and item response theory methods informed item reduction and Delphi process yielded a final questionnaire.ResultsTwo hundred subjects and their care- partners participated in the study (age: 66.4- Â±- 9.6- years disease duration: 9- Â±- 5.5- years median Hoehn and Yahr OFF: 3 mean Unified Parkinson’s Disease Rating Scale (UPDRS) III ON score: 27.4- Â±- 14.9). We assessed the internal consistency, floor and ceiling effects, test- retest reliability, and concurrent validity of NoMoFA.
