Development of a Reliable and Valid Survey Instrument to Measure Nurses' Health Behaviors Towards an Infectious Disease.

Background and Purpose: The purpose of this study is to describe the process for developing a reliable and valid survey instrument guided by the protection motivation theory (PMT) to evaluate nurses' health behaviors toward an infectious disease such as Ebola. Methods: The instrument was developed and tested through a systematic process that included a literature review, focus group, validity testing, and reliability testing. Results: The outcome variable, protection motivation, contained two elements, determined by principal component analysis. The instrument's internal consistency had a Cronbach's alpha of .80 or greater. Conclusion: The development and testing of an instrument based on PMT constructs as the theoretical framework have demonstrated a relationship between the perceived threat toward the disease and the proposed coping process needed to address the disease.

A Cross-Sectional Examination of the Factors Related to Emergency Nurses' Motivation to Protect Themselves Against an Ebola Infection.

INTRODUCTION: The 2014-2016 West African Ebola outbreak impacted the United States. Owing to the sporadic occurrence of the Ebola infection, there is insufficient research regarding how US emergency nurses provide care to patients potentially infected with the Ebola virus and the nurses' motivation to protect themselves when providing care to these patients. This study aimed to investigate the predictors of emergency nurses' protection motivation. METHODS: A cross-sectional design was employed. A survey developed based on a modified Protection Motivation Theory was administered to randomly selected members of the Emergency Nurses Association. Descriptive statistics, nonparametric Kruskal-Wallis H test (as well as post hoc Dunn-Bonferroni test), Spearman rho correlation, and stepwise multiple linear regression were conducted for data analysis. RESULTS: Protection motivation was found in 2 components: proactive and passive protection motivation. Regression analysis indicated that response efficacy (ß = 0.27, P < 0.001) and self-efficacy (ß = 0.17, P < 0.01) significantly predict emergency nurses' proactive protection motivation, whereas perceived vulnerability (ß = 0.26, P < 0.001), response cost (ß = 0.19, P = 0.001), and knowledge (ß = -0.15, P < 0.01) significantly predict emergency nurses' passive protection motivation. DISCUSSION: The results indicate the need for interventions to improve emergency nurses' response efficacy, self-efficacy, and knowledge, while simultaneously reducing the nurses' perceived vulnerability and response cost. Such interventions would be expected to proactively motivate nurses to protect themselves when providing care to patients who exhibit the signs and symptoms of an Ebola infection and reduce their passive protection motivation.

Physician Assistant Students' Knowledge of Zika Virus: A Pilot Study.

OBJECTIVE: The aim of this study was to assess physician assistant students' knowledge about the screening, transmission, management, and prevention of Zika virus infection. BACKGROUND: It is important for health care providers in the United States to recognize the symptoms of Zika so that they can screen, diagnose, and or treat persons exposed to or infected by the virus. Physician assistant students, on completion of their educational program and passing their board examinations, provide care for patients in primary care or specialty settings where they may treat patients who either have the virus or post-virus exposure. METHODS: A convenience sample of 37 students enrolled in a physician assistant studies program in the Midwestern United States completed an in-person self-administered paper-and-pencil questionnaire that tested their knowledge about Zika virus infection. RESULTS: All the respondents knew that the disease is of viral origin; however, only 89% knew that mosquitoes were the natural host. Primary modes of transmission were identified as sexual contact and blood transfusion (47% and 44% of respondents respectively); 47% incorrectly identified amniotic fluid as a transmission mode. More than half (61%) knew that health care providers should ask pregnant women about any possible virus exposure before and during pregnancy at each prenatal visit. Most respondents knew that muscle/joint pain (67%) was one of the symptoms of Zika infection, but only 39%, 25%, and 19% also identified low-grade fever, maculopapular rash, and conjunctivitis respectively as other symptoms. Some participants incorrectly identified antivirals (44%) and nonsteroidal anti-inflammatory medications (36%) rather than the recommended treatments of pain relief (30%) and fever relief (42%) medications for clinical management of the disease.
