N1 - Funding Information: We would like to thank all members of the Dutch Association for Musculoskeletal Medicine (Nederlandse Vereniging voor Artsen Musculoskeletale Geneeskunde, NVAMG) who cooperated in this study. This study has been conducted as part of a larger research effort funded by the Dutch Association for Musculoskeletal Medicine. Caroline B. Terwee is head of the Dutch-Flemish PROMIS National Center and board member of the PROMIS Health Organization. Caroline B. Terwee previously received grants for work on the translation and validation of the PROMIS item banks. Wouter Schuller is one of the owners of Prismascan, a Dutch company that developed an application using PROMIS CAT for routine outcome measurements. Henrica C.W. de Vet, Berend Terluin, Daphne C.

N2 - We evaluated the responsiveness of the Patient Reported Outcome Information System Pain Interference item bank in patients with musculoskeletal pain by testing predefined hypotheses about the relationship between the change scores on the item bank, change scores on legacy instruments and Global Ratings of Change (GRoC), and we estimated Minimal Important Change (MIC). Patients answered the full Dutch-Flemish V1.1 item bank. From the responses we derived scores for the standard 8-item short form (SF8a) and a CAT-score was simulated. Correlations between the change scores on the item bank, GRoC and legacy instruments were calculated, together with Effect Sizes, Standardized Response Means, and Area Under the Curve. GRoC were used as an anchor for estimating the MIC with (adjusted) predictive modeling. Of 1,677 patients answering baseline questionnaires 960 completed follow-up questionnaires at 3 months. The item bank correlated moderately high with the GRoC (Spearman's rho 0.63) and with the legacy instruments (Pearson's R ranging from .45 to .68). It showed a high ES (.97) and Standardized Response Means (.71), and could distinguish well between improved and not improved patients based on the GRoC (Area Under the Curve .77). Comparable results were found for the derived SF8a and CAT-scores. The MIC was estimated to be 3.2 (CI 2.6-3.7) T-score points. Perspective Our study supports the responsiveness of the PROMIS-PI item bank in patients with musculoskeletal complaints. Almost all predefined hypotheses were met (94%). The PROMIS-PI item bank correlated well with several legacy instruments which supports generic use of the item bank. MIC for PROMIS-PI was estimated to be 3.2 T-score points.
