Nursing educators should equip nursing students with sufficient knowledge about coronavirus disease 2019 (COVID-19), perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, self-efficacy, and behavioral intention in order to prevent the spread of COVID-19. The purpose of this study was to use the health belief model to elucidate nursing students’ relationships between knowledge about COVID-19, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, self-efficacy, and behavioral intention. A cross-sectional survey design was adopted and purposive sampling was utilized. A total of 361 nursing students participated in the study. Quantitative analysis was employed for all data analysis. The findings showed that the nursing students had the following mean scores on knowledge of COVID-19 9.43 [standard deviation (SD)1.19], perceived susceptibility 19.41 (SD2.68), perceived severity 20.31 (SD 4.09), perceived benefits 26.52 (SD 4.08), perceived barriers 15.17 (SD5.88), cues to action 3.30 (SD1.70), self-efficacy 17.68 (SD2.83), and behavioral intention 18.46 (SD2.33). Nursing students’ demographic background, knowledge of COVID-19, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy explained 58.1% of the variance in behavioral intention (R 2 = 0.581, F = 29.775, P < .001). Nursing educators can increase nursing students’ knowledge of COVID-19, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy as effective means of health promotion to improve their behavioral intention to prevent the spread of COVID-19.
Visual impairment is associated with disability and poor quality of life. This study aimed to investigate the prevalence and associated risk factors of visual impairment among the suburban elderly in Eastern Taiwan. The cross-sectional research was conducted from April 2012 to August 2012. The ocular condition examination took place in suburban areas of Hualien County. Medical records from local infirmaries and questionnaires were utilized to collect demographic data and systemic disease status. Logistic regression models were used for the simultaneous analysis of the association between the prevalence of visual impairment and risk factors. Six hundred and eighty-one residents participated in this project. The mean age of the participants was 71.4±7.3 years. The prevalence of vision impairment (better eye<6/18) was 11.0%. Refractive error and cataract were the main causes of vision impairment. Logistic regression analysis showed that people aged 65-75 years had a 3.8 times higher risk of developing visual impairment (p=0.021), while the odds ratio of people aged > 75 years was 10.0 (p<0.001). In addition, patients with diabetic retinopathy had a 3.7 times higher risk of developing visual impairment (p=0.002), while the odds ratio of refractive error was 0.36 (p<0.001). The prevalence of visual impairment was relatively high compared with previous studies. Diabetic retinopathy was an important risk factor of visual impairment; by contrast, refractive error was beneficial to resist visual impairment. Therefore, regular screening of ocular condition and early intervention might aid in the prevention of avoidable vision loss.
The Postgraduate Year (PGY) Program allows doctors-in-training to learn about the diagnosis, treatment and nursing of various common, general diseases. These items form the core curriculum and are mostly learned through caring for patients and clinical teaching. Doctors-in-training are evaluated for their knowledge through written tests or assignments, based on which the effectiveness of their training is also assessed; however, this generally produces a negative learning attitude among them. So we introduced the flipped classroom into PGY training program to change PGY students’ learning behavior. Although the flipped classroom is highly valued and has been practiced by teachers in schools of various levels, very few attempts have been made until now to report the learning outcomes achieved through the flipped classroom by means of rigorous research methods. Therefore we tried to employed Ajzen and Fishbein’s (1980) theory of reasoned action and Bandura’s self-efficacy to predict and explain the participants’ behavioral intention when participating in the core curriculum learning of the flipped classroom and to assess the change in students’ learning behavior and learning effectiveness. From August 2013 to July 2014, 39 PGY students from the General Surgery of the Tri-Service General Hospital were selected as the participants of this study. The control group included 43 students of the previous year, that is, the year before the intervention of the flipped classroom. A comparative analysis was performed. The questionnaire’s related matrices indicated highest correlation between self-efficacy and behavioral intention (r = 0.491, P < 0.01), followed by attitude (r = 0.365, P < 0.01) and subjective norms (r = 0.360, P < 0.01.) All three showed positive correlations with behavioral intention; among attitude, subjective norms, and self-efficacy, the pairwise correlations also reached significance level. The flipped classroom can indeed change PGY students’ the learning behavior from “passive learning” to “active learning.”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
