BACKGROUND: Medication Treatment Satisfaction (M-TS) from the patients' perspective is important for comprehensively evaluating the effect of medicines. The extent to which current patient-reported outcome measures (PROMs) for M-TS are valid, reliable, responsive, and interpretable remains unclear. To assess the measurement properties of existing PROMs for M-TS and to highlight research gaps. METHODS: Using PubMed, Embase (Ovid), Cochrane library (Ovid), IPA (Ovid), PsycINFO, Patient-Reported Outcome and Quality of Life Questionnaires biomedical databases, and four Chinese databases, we performed a systematic search for studies addressing the development and validation of PROMs for M-TS. Based on the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guideline, pairs of reviewers independently assessed the measurement properties of the PROMs and rated the quality of evidence on the measurement properties of each PROM. (The Open Science Framework registration: https://doi.org/10.17605/OSF.IO/8S5ZM ). RESULTS: This review identified 69 PROMs for M-TS in 114 studies (four generic, 32 disease-specific, and 33 drug-specific) of which 60 were intended for adults. All provided limited or no information regarding interpretability. Most demonstrated appropriate construct validity including convergent validity (39/69) and discriminative or known-groups validity (40/69) (high to moderate quality of evidence). Only a few provided evidence of sufficient content validity (8/69), structural validity (13/69), and internal consistency (11/69). Of 38 PROMs reporting test-retest reliability, results in 24 provided evidence of satisfactory test-retest reliability (18 with high to moderate, 6 with low to very low quality of evidence). Few PROMs reported responsiveness (16/69). Two generic PROMs (Treatment Satisfaction Questionnaire for Medication initial Version 1.4, TSQM-1.4; Treatment Satisfaction with Medicines Questionnaire, SATMED-Q) and one drug-specific PROM (Insulin Treatment Satisfaction Questionnaire, ITSQ) demonstrated both satisfactory validity and reliability. CONCLUSIONS: Most existing PROMs for M-TS require further exploration of measurement properties. Reporting guidelines are needed to enhance the reporting quality of the development and validation of PROMs for M-TS.
