Designing and psychometric assessment of the scale of factors influencing HPV vaccine uptake behaviors in young adults

Abstract

Background In order to increase HPV vaccination, it is necessary to identify the factors influencing vaccination behavior among different cultures and the young adult populations. To evaluate the factors influencing HPV vaccine uptake behaviors, valid, reliable, and culture-compatible scales are required. This study was conducted with the aim of designing and psychometric assessment of the scale of factors influencing HPV vaccine uptake behaviors in Young Adults (FI(HPV)VUBYA) in Iran. Methods The present study was carried out in a mixed-method in two steps: (a) Generating items using a qualitative study and literature review and (b) Reducing items by psychometric assessment of the designed scale. The initial set of items (N = 80) was prepared based on a qualitative study and literature review. A total of 400 young adults participated in online data collection from November 2019 to February 2020. The validity (face, content, and construct) and reliability (internal consistency and stability) of the scale were evaluated. Results The exploratory factor analysis (EFA) revealed that the scale has 7 factors, explaining 57.84% of the total extracted variance. There was also a knowledge factor that EFA did not analyze, but its validity and reliability were evaluated with 7 other factors. The results of confirmatory factor analysis showed a good model fit. Convergent and divergent validity of the scale was accepted for all factors. Good reliability was also reported for the scale. Conclusion FI(HPV)VUBYA 8-factor scale has good validity and reliability among young Iranian adults. Due to its appropriate psychometric properties, this scale can be used on this population in future studies.

Assessment of HPV Knowledge and Awareness among Students and Staff at IBB University, Niger State, Nigeria: Implications for Health Education and Prevention

“…The aim was to understand the distribution of ages among the participants and to examine whether it followed a normal distribution. The Shapiro−Wilk test is commonly used to evaluate the normality assumption of a dataset [ 23 ]. In this analysis, the test statistic (W) was calculated to be 7.22 and the corresponding p -value = 0.000, indicating a significant departure from normality [ 31 ].…”

“…Data collection instruments used for this study consisted of the demographic survey and other forms to measure knowledge and awareness of HPV. The following forms were adapted to measure the knowledge and awareness of HPV: HPV Infection Awareness Questions [ 21 ], HPV Infection Knowledge Questions (Scale) [ 21 , 22 ], HPV Vaccine Knowledge Questions (Scale) [ 21 , 23 ] and Cervical Cancer Awareness on OC Pills [ 24 , 25 , 26 ]. The data instrument was adapted for use in the study settings.…”
