The Medical Outcome Study Social Support Survey (MOS-SSS): A psychometric systematic review.

AIMS: To evaluate and synthesize psychometric properties of the MOS-SSS and to identify quality versions of MOS-SSS for use in future research and practice. DESIGN: A psychometric systematic review. DATA SOURCES: Articles about the translation, adaptation, or validation of the MOS-SSS in Medline, PubMed, CINAHL, and Web of Science and their reference lists published before 11 November 2022. REVIEW METHODS: The review followed the Consensus Standards for the Selection of Health Measurement Instruments guidelines. RESULTS: The review included 35 articles. Eleven versions of MOS-SSS (3, 4, 5, 6, 8, 12, 13, 16, 18, 19, and 22 items) have been validated in various populations and 13 languages. Of 14 studies developing a translated version of MOS-SSS, four studies performed both an experts' evaluation of content validity and a face validity test; two studies reported translation evaluation in the form of a content validity index. Of 35 studies, six performed both exploratory factor analysis and confirmatory factor analysis for structural validity; hypotheses and measurements for construct validity testings were often not clearly stated; two examined criterion validity; and four assessed cross-cultural validity. Internal consistency reliabilities were commonly examined by calculating Cronbach's alpha and reported satisfactory. Five studies analysed test-retest reliabilities using intra correlation coefficient. Methodological concerns exist. CONCLUSION: The English 19-item, Farsi Persian 19-item, and Vietnamese 19-item versions are recommended for future use in research and practice. Italian 19-item and Malaysian 13-item versions are not recommended to be used in future research and practice. All other versions considered in this review have potential use in future research and practice. Proper procedures for developing a translated version of MOS-SSS and validating the scale are recommended. IMPACT: The review identified quality versions of MOS-SSS to measure social support in future research and practice. The study also indicated methodological issues in current validation studies. Application of the study findings and recommendations can be useful to improve outcome measurement quality and maximize the efficiency of resource use in future research and practice. NO PATIENT OR PUBLIC CONTRIBUTION: This systematic review synthesized the evidence from previous research and did not involve any human participation.

Self-report instruments for measuring patient dignity: A psychometric systematic review.

AIMS: To synthesize and evaluate the psychometric properties of self-report instruments that measure patient dignity. DESIGN: A psychometric systematic review. DATA SOURCES: A comprehensive search of studies published from inception until February 17, 2022, was performed using PubMed, Embase, CINAHL, Web of Science, and Scopus. REVIEW METHODS: The methodological quality of the psychometric studies was evaluated following the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. RESULTS: Eleven self-report instruments that evaluate dignity were identified. For most instruments, psychometric properties, including reliability, cross-cultural validity, responsiveness, and measurement error, had not been adequately examined. The Patient Dignity Inventory (PDI), the Jacelon's Attributed Dignity Scale (JADS), and the Inpatient Dignity Scale (IPDS) had acceptable content validity, structure validity, and internal consistency to measure dignity among adult patients under palliative care, community-dwelling older adults, and inpatients receiving daily care. CONCLUSION: The PDI, the JADS, and the IPDS are recommended for future clinical practice and research to measure dignity among adult patients under palliative care, community-dwelling older adults, and inpatients receiving daily care. Early identification of patients' dignity-related problems in nursing care can prevent negative health outcomes and help develop a timely intervention to promote patients' health and recovery. IMPACT: Given that the psychometric properties of the existing self-report dignity instruments have not been systematically assessed, the present review utilized comprehensive methods according to COSMIN to evaluate and determine the most appropriate measure for research and practice. The PDI, the JADS, and the IPDS demonstrated satisfactory psychometric properties and are, thus, recommended for clinical and research applications. Nursing professionals can employ these instruments to assess and promptly identify dignity issues among both young and older adults in hospitals and communities.
