CONSTRUCT VALIDITY ANALYSIS OF THE GENETICS AND GENOMICS IN NURSING PRACTICE SURVEY: OVERCOMING CHALLENGES IN VARIABLE RESPONSE INSTRUMENTS.

ABSTRACT: Background and Purpose: We evaluated the construct validity of the Genetics and Genomics Nursing Practice Survey by investigating the factoral structure, while attempting to account for varied response structures of the items. Methods: Exploratory factor analyses provided insights into item loadings. Confirmatory factor analyses and a version of common methods bias analyses evaluated construct validity while considering the instrument's structural limitations. Structural equation models provided information regarding model fit. Results: The 7-factor model fit these data slightly better (AIC ≈ 169,405; RMSEA = .052) than did the 5-factor model (AIC ≈ 183,599; RMSEA = .063). Neither the CFI or TLI met commonly-accepted thresholds for adequate model fits. Conclusion: The response format of the GGNPS created challenges in evaluating the instrument for construct validity. Nonetheless, these results support the theory-based construct validity of the GGNPS.

Project description:BACKGROUND: Since more people are reaching older and older ages, healthcare systems are becoming in need of more and more knowledgeable nurses to meet the specific health care needs of older persons. Several instruments exist to measure and evaluate students' knowledge of older persons, ageing, and gerontological care; however, unequivocal evidence on their use and psychometric properties is scarce. The aim of the study was to validate a revised version of Palmore's Facts on Aging Quiz (FAQ). METHODS: A cross-sectional, exploratory study was conducted. Palmore's FAQ version 1 and Facts on Aging Mental Health Quiz were used as bases for the development of a revised FAQ instrument. Three researchers translated these instruments into Dutch. A panel of nine experts in geriatric research and gerontological care evaluated the translation and the face and content validity of the instrument. We used a cross-sectional, exploratory design to assess its internal consistency and construct validity. Cronbach's alpha coefficients, exploratory factor analysis, and the known-groups technique were used for these analyses. RESULTS: Based on the experts' consensus, a revised version of the FAQ, consisting of 36 items, was produced. Exploratory factor analysis did not reveal underlying constructs suggesting that the revised version encloses a more general concept of knowledge (e.g. about older persons, aging, gerontological care). Using the known-groups technique, we validated the instrument, showing that it discriminates between the knowledge of first- and third-year nursing students. The overall Cronbach's coefficient of 0.723 was acceptable and changed minimally (from 0.708 to 0.724) when items were removed. CONCLUSION: We conclude that the revised version of the FAQ can be used to properly evaluate nursing students' knowledge about older persons and gerontological care, as reasonable reliability and validity were established for this revised version of the FAQ.
