The purpose of this study was to assess the psychometric properties of the Barriers or Facilitators to Using Research in Practice (BARRIERS) scale for use in Korea.
A cross-sectional study design was used with 364 nurses working in clinical settings. Item analysis was conducted and convergent and discriminant validity were evaluated using confirmatory factor analysis. Internal consistency reliability was evaluated using Cronbach's alpha coefficients.
Confirmatory factor analysis revealed a 4-factor structure with 25 items that explained 62.9% of the variance. Convergent and discriminant validity were confirmed as examining the factor loading, average variance extracted, and composite reliability. The values of factor loading for 25 items were having higher estimate than criterion and the average variance extracted value for 4 factors ranged from .575 to .667. The Cronbach's alpha was .90 for the 25 items.
The Korean version of the 25-item BARRIERS scale was a reliable and valid scale to measure barriers to research use in Korean health care settings. Based on this psychometric evaluation, research barriers and its associated factors will be investigated using the Korean version of the BARRIERS scale in further study.
本研究旨在评估用于韩国的实践中运用研究的障碍或促进因素(BARRIERS)量表的心理测量特性。
采用横断面研究设计,对364名临床护士进行研究。进行项目分析,并使用验证性因素分析评估收敛效度和区分效度。使用克朗巴赫α系数评估内部一致性信度。
验证性因素分析揭示了一个包含25个条目的四因素结构,该结构解释了62.9%的方差。通过检查因素负荷、提取的平均方差和组合信度,确认了收敛效度和区分效度。25个条目的因素负荷估计值高于标准,4个因素的提取平均方差值在0.575至0.667之间。25个条目的克朗巴赫α系数为0.90。
25个条目的韩语版BARRIERS量表是测量韩国医疗环境中研究应用障碍的可靠且有效的量表。基于此心理测量评估,在进一步研究中将使用韩语版BARRIERS量表调查研究障碍及其相关因素。
