- Parental hesitancy toward children vaccination: A multi-country psychometric and predictive studyPublication . Sharif-Nia, Hamid; She, Long; Allen, Kelly-Ann; Maroco, J. P.; Kaur, Harpaljit; Arslan, Gökmen; Gorgulu, Ozkan; Osborne, Jason; Rahmatpour, Pardis; Khoshnavay Fomani, FatemehAim Understanding vaccine hesitancy, as a critical concern for public health, cannot occur without the use of validated measures applicable and relevant to the samples they are assessing. The current study aimed to validate the Vaccine Hesitancy Scale (VHS) and to investigate the predictors of children’s vaccine hesitancy among parents from Australia, China, Iran, and Turkey. To ensure the high quality of the present observational study the STROBE checklist was utilized. Design A cross-sectional study. Method In total, 6,073 parent participants completed the web-based survey between 8 August 2021 and 1 October 2021. The content and construct validity of the Vaccine Hesitancy Scale was assessed. Cronbach’s alpha and McDonald’s omega were used to assess the scale’s internal consistency, composite reliability (C.R.) and maximal reliability (MaxR) were used to assess the construct reliability. Multiple linear regression was used to predict parental vaccine hesitancy from gender, social media activity, and perceived financial well-being. Results The results found that the VHS had a two-factor structure (i.e., lack of confidence and risk) and a total of 9 items. The measure showed metric invariance across four very different countries/cultures, showed evidence of good reliability, and showed evidence of validity. As expected, analyses indicated that parental vaccine hesitancy was higher in people who identify as female, more affluent, and more active on social media. Conclusions The present research marks one of the first studies to evaluate vaccine hesitancy in multiple countries that demonstrated VHS validity and reliability. Findings from this study have implications for future research examining vaccine hesitancy and vaccine-preventable diseases and community health nurses.
- A psychometric lens for e-learning: Examining the validity and reliability of the persian version of University Students’ Engagement Inventory (P-USEI)Publication . Sharif Nia, Hamid; Azad Moghddam, Hamed; Maroco, J. P.; Rahmatpour, Pardis; Allen, Kelly-Ann; Kaur, Harpaljit; Kaveh, Omolhoda; Gorgulu, Ozkan; Pahlevan Sharif, SaeedStudent engagement is a critical component of e-learning, which became an important focus for most academic institutions during the COVID-19 pandemic. University students’ engagement is measured using various scales with diferent subscales. This study aimed to evaluate the psychometric properties of the Persian version of the University Student Engagement Inventory (P-USEI). A cross-sectional methodology study was conducted among Iranian university students (n =667) from April to May 2020. After forward–backward translation, the content, and construct validity, and reliability of the scale were assessed. The results obtained from the confrmatory factor analysis confrmed that the P-USEI has three factors: cognitive, emotional, and behaviour. The fndings of the study supported the adequate reliability, factorial, convergent, and discriminant validities of P-USEI in a sample of Iranian students. The P-USEI dimensions have predictive value for important academic variables that can be generalized by developing the research through a psychometric evaluation on student engagement.
