Abstract

  Background & Aim: The Roy’s adaptation model is a helpful instrument to be used in treatment processes of patient s with chronic diseases. According to chronic nature of amputee veterans' diseases, it is expected that the implementation of care plan s based on this model can increase adaptation in the patients . The present study was performed to design and determine validity and reliability of a researcher-designed adaptation questionnaire based on the Roy’s adaptation model on war veterans with lower limb amputation .

  Methods & Materials: This study was conducted among war veterans referred to the veteran clinic of Orthotics and Prosthetics center using convenience sampling method during 2012-2014 . M ain concepts of adaptation defined based on the Roy’s adaptation model were used to provide items. The validity and reliability of the questionnaire was assessed using the content validity index (CVI), content validity ratio (CVR), face validity, internal consistency (Cronbach's alpha), and stability (test-retest reliability) tests.

  Results: Thirty five items were developed including 15 items on physiological area, 11 items on self-concept area, four items on dependence/ independence area, and five items on role playing area. The CVI was 0.95 . The Cronbach's alpha was 0.78. The correlation coefficient values ​​were more than 0.7 in each area .

  Conclusion: The psychometric analysis of the questionnaire showed proper validity and reliability for measuring adaptation on war veterans with lower limb amputation. The questionnaire is recommended to be used in nursing practice .

Abstract

Background & Aim: Because of the importance of empathy and positive impact on the relationship between patients and health care providers, as well as the lack of valid instrument to assess student's empathy in health domain, this study aimed to examine the factor structure and reliability of the Persian version of JSE-HPS in the students of the School of Nursing and Midwifery, Mashhad University of Medical Sciences in Iran.

Methods & Materials: In this cross-sectional study, 398 nursing and midwifery students of Mashhad University of Medical Sciences were selected using stratified random sampling. The data collection instrument was JSE-HP. The confirmatory factor analysis was used to investigate the factor structure of the instrument, and the Cronbach's alpha coefficient was applied to examine its reliability. The data analysis was done using LISREL version 8.8 and SPSS version 20.

Results: The results of the confirmatory factor analysis model showed given that fitness model parameters, including CFI, GFI, AGFI and NFI were approximately 1 and RMSEA index was less than 0.1, the fitness of three-factor model is appropriate. The Cronbach's alpha coefficient for the total instrument was 0.63.

Conclusion: The current study confirmed the three-factor structure of the Persian version of JSE-HPS (20 items), included perspective taking, compassionate care and standing in patient’s shoes. Thus, this instrument is appropriate to measure empathy for patient in the health service provider students.

Abstract

Background & Aim: Assessment of sexual health literacy requires an appropriate tool. The purpose of this study was to develop and validate a questionnaire to evaluate the level of sexual health literacy among Iranian adults.
Methods & Materials: This study was designed in two phases in Tehran during 2017-2018. In the first step, the questionnaire was developed by item generation through expert panel and literature review. In the second step, the assessment of psychometric properties of the questionnaire including face, content, and structure validity (exploratory factor analysis) and convergence criterion (using general health literacy questionnaire) were done. Reliability of the questionnaire was assessed by internal consistency (Cronbach’s alpha) and intraclass correlation coefficient (ICC). Data were analyzed using the SPSS software version 21.
Results: The content validity indices (CVI and CVR) for all items were 0.84 and 0.81, respectively. Exploratory factor analysis identified four factors including skills of access, reading and understanding, evaluation and analysis, and application of information that explained %68.1 of the variance. Convergent validity of the questionnaire showed a correlation between the questionnaire’s dimensions and general health literacy questionnaire in the range of 0.31 to 0.70. The SHELA showed a high internal consistency reliability with Cronbach’s alpha, ranging from 0.84 to 0.94 and intraclass correlation coefficient (ICC), ranging from 0.90 to 0.97.
Conclusion: The psychometric assessment of the 40-item questionnaire (SHELA) indicates desirable validity and reliability. This questionnaire is suggested for assessing the level of sexual health literacy of adults in future studies.
