Health Status Instruments Reviewed. 1 (SF-36): MOS Short Form 36v2 [34, 35]; 2 (SF-12): MOS Short Form 12 [36]; 3 (EQ-5D): EuroQol 5D [39]; 4 (COOP): Dartmouth COOP Charts [37]; 5 (CMP) Change in Main Problem [45,46,47] 6 (MYMOP): Measure Yourself Medical Outcomes Profile v2 [43]; 7 (PPQ): Patient Perception of Quality [32] 8 (HowRU) HowRU [50]; 9 (ORIDL) Outcomes Related to Impact on Daily Living [33]; 10 (CIMOS) Complementary and Integrative Medical Outcomes Scale [52]. Scale (a) S = Status (capturing status at a point in time). T = Transitional (capturing change over a period of time). Adaptability (b) S = Standardised (standard list of items) I = Individualised (respondents can select, identify or weight items). Dimensionality (c) P = Profile of scores. I = Index (single score). U = Utility (single preference-based score which can generate a QALY). Extent of psychometric testing (d) Extensive (Widespread validation in different populations/countries and/or > 1000 citations). Moderate (Independent validation and/or > 100 citations). Low (Validation by original authors and/or < 100 citations). Responsiveness (e) Unknown (responsiveness not known or tested). Low (responsiveness shown in at least one study). Moderate (Repeated evidence for responsiveness, including in primary care). High (responsiveness shown in primary care studies where other leading PROMs are not responsive)
