Background: Stroke has evolved to become a chronic disease and a major public health challenge. To adequately capture the full disease burden of stroke patients, the assessment of health-related quality of life (HRQoL) and thus the performance of respective measures is increasingly relevant. The aim of this analysis was to compare the measurement properties of two self-report instruments, the EQ-5D-5L and the Stroke Impact Scale 2.0. Methods: The data used for the analysis was derived from a quasi-experimental case management study for mildly to moderately affected incident stroke and transient ischemic attack (TIA) patients aged ≥ 18 in Germany. Data was collected patient-individually at 3, 6 and 12 months after initial stroke. The EQ-5D-5L and SIS 2.0 were compared in terms of feasibility, ceiling and floor effects, responsiveness and known-groups validity (Kruskal-Wallis H and Wilcoxon rank-sum test). Results: A response for all three follow-ups is available for n = 855 patients. The feasibility of the EQ-5D-5L is determined as good (completion rate: 96.4–96.6%, ≥ one item missing: 3.2 − 3.3%), whereas the SIS 2.0 is moderately feasible (overall completion rate: 44.9–46.1%, ≥ one item missing in domains: 4.7 − 28.7%). The SIS 2.0 shows substantial ceiling effects in comparable domains (physical function: 10.4 − 13%, others: 3.5–31.3%) which are mainly larger than ceiling effects in the EQ-5D-5L index (17.1–21.5%). In terms of responsiveness, the EQ-5D-5L shows small to moderate change while the SIS 2.0 presents with moderate to large responsiveness. The EQ-5D-5L index, mobility, usual activities and Visual Analogue Scale show known-groups validity (p < 0.05). Content-related domains of the SIS 2.0 show known-groups validity as well (p < 0.05). However, it is compromised in the emotion domain in both measures (p > 0.05). Conclusions: The EQ-5D-5L seems to be slightly more suitable for this cohort. Nonetheless, the results of both measures indicate limited suitability for TIA patients. Large-scale studies concerning responsiveness and known-groups validity are encouraged. Trial registration: The study was registered in the German Clinical Trials Register, retrospective registration on 21.09.2022. Registration ID: DRKS00030297. [ABSTRACT FROM AUTHOR]
