Measurement Properties Of Self-report Instruments Research Articles

Systematic review of measurement properties of self-reported instruments for evaluating therapeutic communication.

A systematic review was carried out to examine measurement tools of therapeutic relational communication, using an electronic search of the following databases: PubMed, LILACS, CINAHL, CiberIndex, Scielo and Scopus. The project followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis and the protocol recommended by the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) panel. Thirteen instruments were included in the review. and their measurement properties were tested. The most common communication elements found in the measuring instruments were: empathy, respect, listening, contact, communicative competence, communication quality, and communication skills. Studies that used a theoretical foundation were based on patient-centered humanistic models. Empathy, respect, controlled contact, and other basic elements of interpersonal communication were most commonly found among the measuring regents. In conclusion, this review analyzed the theoretical foundations of the components of instruments used to measure therapeutic relational communication in the nursing field.

Systematic review of measurement properties of self-reported instruments for evaluating self-care in adults.

The aims of this study were as follows: to identify instruments developed to assess self-care in healthy adults; to determine the theory on which they were based; their validity and reliability properties and to synthesize the evidence on their measurement properties. Many instruments have been developed to assess self-care in many different populations and conditions. Clinicians and researchers should select the most appropriate self-care instrument based on the knowledge of their measurement properties. Systematic review of measurement instruments according to the protocol recommended by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) panel. PubMed, Embase, PsycINFO, Scopus and CINAHL databases were searched from inception to December 2015. Studies testing measurement properties of self-report instruments assessing self-care in healthy adults, published in the English language and in peer review journals were selected. Two reviewers independently appraised the methodological quality of the studies with the COSMIN checklist and the quality of results using specific quality criteria. Twenty-six articles were included in the review testing the measurement properties of nine instruments. Seven instruments were based on Orem's Self-care theory. Not all the measurement properties were evaluated for the identified instruments. No self-care instrument showed strong evidence supporting the evaluated measurement properties. Despite the development of several instruments to assess self-care in the adult population, no instrument can be fully recommended to clinical nurses and researchers. Further studies of high methodological quality are needed to confirm the measurement properties of these instruments.

Evaluation of the Measurement Properties of Self-reported Medication Adherence Instruments Among People at Risk for Metabolic Syndrome: A Systematic Review.

The purpose of this study was to present a systematic review of available published studies that evaluated the measurement properties of self-reported instruments assessing global medication adherence in adults at risk for metabolic syndrome. The authors searched PubMed, EMBASE, PsycINFO, and CINAHL in January 2015 for appropriate studies. The methodological quality (based on reliability, validity, responsiveness, and interpretability) of selected studies was assessed with the COSMIN checklist (Consensus-Based Standards for the Selection of Health Measurement Instruments). Of the 44 studies reviewed, 32 used classical test theory, and 14 used self-reported medication adherence instruments. More than half the studies included patients with hypertension, followed by diabetes, dyslipidemia, and increased body mass index. Among the measurement properties, internal consistency, hypothesis testing, and structural validity were frequently assessed items, whereas only 1 study evaluated responsiveness, and none evaluated measurement error. The MMAS-8 (Morisky Medication Adherence Scale-8 items) and the Hill-Bone scale were the most frequently used instruments. They were found to be well validated, with strong evidence for internal consistency and strong positive evidence for reliability, structural validity, hypothesis testing, and criterion validity. The MMAS-8 and Hill-Bone scale seem to be well-validated instruments for assessing medication adherence in adults at risk for metabolic syndrome. These findings may assist clinicians with selecting the appropriate instruments for assessing medication adherence in this population. However, further studies might be needed to define concepts to better understand the dimensions of each medication adherence instrument.

An approach to modifying self-report instruments.

The Rasch model, a simple latent trait model was applied to responses to a 21-item self-report instrument. Items were assigned values reflective of interval scale measurement. To modify the instrument, items below the calibrated mean were eliminated. The proposed revision contains fewer items with known scale values and only those items that are the strongest indicants of the variable in question. The present work suggests that the Rasch and similar models are useful for increasing the measurement properties of self-report instruments.
