The Nursing Research Self-Efficacy Scale (NURSES) was designed to measure individual nurses' degree of research self-efficacy and their perceptions regarding their unit's collective support of research use. Development for the NURSES instrument spanned a 4-year period, which included initial development, revisions, and psychometric evaluations.
The NURSES is a 38-item Likert-scale instrument developed through ongoing instrument validation that included content validation and exploratory and confirmatory analysis. The 5 subscales include obtaining science-based knowledge resources, critically reading and evaluating quantitative research literature, critically reading and evaluating qualitative research literature, understanding and applying theory, and collective research efficacy.
Over a 4-year period, approximately 1000 practicing nurses from multiple hospitals responded to the instrument. Exploratory and confirmatory factor analyses supported the existence of four subscales for research self-efficacy and one subscale for collective research efficacy. Reliability for the subscales was excellent, ranging from .94 to .97.
Hospitals may wish to use the NURSES instrument as an orientation tool, or to examine relationships between research efficacy and nurses' professional development. Health care facilities on a Magnet journey might also use the NURSES instrument to assess their nursing staff as they pursue evidence-based practice and conduct research.
护理研究自我效能量表（NURSES）旨在测量个体护士的研究自我效能程度以及他们对所在科室对研究应用的集体支持的认知。NURSES工具的开发历时4年，包括初始开发、修订和心理测量评估。
NURSES是一个包含38个条目的李克特量表工具，通过持续的工具验证开发而成，包括内容验证以及探索性和验证性分析。5个分量表包括获取基于科学的知识资源、批判性阅读和评估定量研究文献、批判性阅读和评估定性研究文献、理解和应用理论以及集体研究效能。
在4年时间里，来自多家医院的约1000名执业护士对该工具进行了回应。探索性和验证性因素分析支持了研究自我效能的四个分量表和集体研究效能的一个分量表的存在。各分量表的信度极佳，范围从0.94至0.97。
医院可能希望将NURSES工具用作一种导向工具，或用于研究效能与护士专业发展之间关系的研究。处于“磁石”之旅的医疗机构在追求循证实践和开展研究时，也可使用NURSES工具来评估其护理人员。
