RESULTS From 2,234 records screened, 28 studies were eligible for inclusion (observational n = 22 and experimental n = 6). Across studies, 12 different instruments were identified (dyspnoea-specific n = 3, subscale of a comprehensive instrument n = 9). Most instruments (n = 11, 92%) assessed a single domain (intensity n = 6, unpleasantness n = 6 and impact/burden n = 5). Studies reported a rationale for measuring dyspnoea (n = 26) as either a characteristic of the participant cohort (n = 14) or as an outcome (n = 14). CONCLUSIONS S
