“…It is a matter of degree rather than an ‘all or nothing’ concept’ (Carmines & Zellar 1979). ‘In reality…it is not possible to take one form of measurement validity in isolation, as several forms may be applicable’ (Gould 1994, p. 102).…”

“…Face validity is directly related to the ‘subjects acceptance of the text’ (Payton 1988). ‘The measurement tool must be understandable and perceived as relevant by the subjects to ensure their co‐operation and motivation’ (Gould 1994, p. 99). Face validity is not tested using statistical procedures.…”

“…This is because the domain of content must first be defined (Rothstein 1985, Arnell & Sim 1993) and then it must be investigated to see if the measurement scale adequately reflects the domain (Gould 1994). The difficulty for researchers with content validity is there is no definitive list of ‘correct content’ (Gould 1994). It is, therefore, impossible to sample the content of a concept and establish total content validity (Arnell & Sim 1993).…”

Aims. To explore and explain the different concepts of reliability and validity as they are related to measurement instruments in social science and health care. Background. There are different concepts contained in the terms reliability and validity and these are often explained poorly and there is often confusion between them. Design. To develop some clarity about reliability and validity a conceptual framework was built based on the existing literature.Results. The concepts of reliability, validity and utility are explored and explained. Conclusions. Reliability contains the concepts of internal consistency and stability and equivalence. Validity contains the concepts of content, face, criterion, concurrent, predictive, construct, convergent (and divergent), factorial and discriminant. In addition, for clinical practice and research, it is essential to establish the utility of a measurement instrument. Relevance to clinical practice. To use measurement instruments appropriately in clinical practice, the extent to which they are reliable, valid and usable must be established.

Background: Nursing education is designed to prepare competent nurses to meet the current and future health care needs of society. Changes to nursing education, especially at post graduate level, will therefore likely be influenced by the on-going developments in healthcare and socio-economic factors. Objective:The primary objective of this study is to develop and validate an instrument that explores the beliefs of Registered Nurses about Postgraduate education in the context of specialist nursing practice in Australia (specialty education). Methods:The Nurses' Attitudes Towards Post Graduate Education (NATPGE) instrument was sent to an expert panel to undertake judgment-quantification (content validity testing). Content Validity Index (CVI) based on expert ratings of relevance was used as a method of quantifying content validity for the NATPGE instrument. A convenience sample of 25 registered nurses was selected from four major Queensland tertiary hospitals to assess the face validity of the instrument. A random sample of 100 registered nurses from the Nurses and Midwives e-Cohort Study (NMeS) were invited to participate in test-retest procedures to assess the reliability of NATPGE overtime. The instrument was administered at two different time points, 3 weeks apart, under similar conditions.Results: Content and face validity was assessed using descriptive statistics. For the test-retest reliability, data were analysed on an item by item basis to calculate the intra-rater reliability using the weighted kappa (k w ) statistic. The NATPGE instrument attained moderate test-retest reliability. 80% of the items on the instrument reached a fair to moderate agreement between the test and retest. Conclusions:There is a need for development of a robust psychometric instrument to explore Registered Nurses' Attitudes Towards Post Graduate Education (NATPGE) and this research is the first step in addressing this need.

The issue of measurement validity in health-care research

Abstract: The use of valid clinical measurement is the basis of effective clinical practice. This article investigates the concept of measurement validity by exploring face, construct, content and criterion-related validity.
