Zusammenfassung	COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) is a systematic framework and 10-item checklist developed by Mokkink et al. (2010) to evaluate the methodological quality of studies that assess the measurement properties of patient-reported outcome measures (PROMs), questionnaires, and clinical scales. COSMIN guides the development, validation, and selection of health measurement instruments across clinical research and practice.	The Critical Appraisal Skills Programme (CASP) RCT Checklist is a practical, widely adopted tool developed by the UK-based Critical Appraisal Skills Programme (founded 1993) for assessing the methodological quality and relevance of published randomized controlled trials. Unlike numeric scoring scales, it uses 11 structured questions with yes/no/cannot tell responses to guide critical appraisal in a format accessible to busy clinicians, researchers, and educators.
