Psychometric properties of End‐of‐Life Caregiving Experience Appraisal Scale: Iranian critical care nurses

Abstract

Background: Healthcare providers should be able to provide good quality end of life care. A tool to evaluate the positive and negative consequences of caring for dying patients is warranted. Aim:The aim of this study was to evaluate the psychometric properties of the Persian version of the End-of-life Caregiving Experience Appraisal Scale (EOLCAS). Methods: This research was conducted in two phases. Phase I: The World Health Organization Protocol of forward-backward translation and an expert panel in order to determine face and content validity. Phase II: Survey development with 310 nurses who worked in critical care units, construct validity (construct, convergent and divergent validity), internal consistency (Average inter-item correlation, Cronbach's alpha and Omega McDonald's) and construct reliability were evaluated. Results:The exploratory factor analysis showed that the present scale has four factors:Negative Physical-emotional and social consequences, transcendental communication, information deficits, and future rumination which explained 83.92% of the overall extracted variance. Convergent and divergent validity was confirmed for all factors. The internal consistency and construct reliability were acceptable. Conclusion:The scale has a multidimensional concept that is sufficiently reliable and the use of the scale would be helpful in measuring consequences of caring for dying patients.Relevance to clinical practice: This scale makes a significant contribution in that it helps in the recognition of positive and negative consequences for critical care nurses' caring for dying patients.

The translation and psychometric assessment of the perception of empowerment in midwifery scale: the Persian version

“…The Cronbach's alpha and McDonald's omega of the five extracted factors were acceptable (0.7<). Also, as shown in Table 2, the AIC was between 0.346 and 0.626 for all the factors, which is considered good [26].…”

Psychometric evaluation of the heart failure somatic perception scale in Iranian heart failure patients: a cross-sectional study

“…The items’ content validity ratio (CVR) and content validity index (CVI) was computed to evaluate the quantitative content validity. On a three-point scale, fifteen faculty members who were educators in cardiac care were asked to rank the HFSPS items’ essentiality: Not essential: 1, useful but not essential: 2, and essential: 3 18 , 19 . A minimum acceptable CVR of 0.62 is necessary when there are up to 10 panellists 20 .…”
