A readiness assessment for identifying and measuring variables that can facilitate evidence-based nursing (EBN) is important. Attitude towards EBN is one of its components. However, questionnaires that exclusively measure attitude to EBN do not exist in Spanish-speaking contexts.
This paper is a report of the development and psychometric testing of a Spanish-language assessment tool: the Evidence-Based Nursing Attitude Questionnaire (EBNAQ).
The questionnaire was developed in three phases: item generation through a review of scientific literature and focus groups; item selection through an expert review; content and construct validity testing, and internal consistency reliability testing. The instrument was validated in terms of construct validity by a factorial analysis and content validity by grouping the items into the three categories of attitude: cognitive, affective and behavioural. Data were collected from May to November of 2008.
The questionnaire was validated in a sample of 219 Spanish community nurses, who had a mean age of 43.21 (SD 10.3) years, and 64.5% (141) were women. A total of 54.3% (121) had been working in the community for more than 10 years. The questionnaire consisted of 15 items grouped into the three factors that make up the concept of attitude. Cronbach's alpha was 0.853 for the entire questionnaire. The factor solution explained 54.70% of the variance.
The EBNAQ is brief, making it a user-friendly tool. It is the first Spanish-language questionnaire that exclusively measures attitude towards EBN in nurses who work in the community. The EBNAQ can be used efficiently in research and practice settings to better understand nurses' attitudes towards evidence-based practice.
进行准备情况评估以识别和衡量可促进循证护理（EBN）的变量非常重要。对 EBN 的态度是其组成部分之一。然而，在西班牙语环境中，不存在专门衡量对 EBN 的态度的问卷。
本文旨在报告西班牙语评估工具——循证护理态度问卷（EBNAQ）的开发和心理测量学测试结果。
该问卷分三个阶段开发：通过文献回顾和焦点小组生成条目；通过专家审查选择条目；内容和结构有效性测试以及内部一致性信度测试。该工具通过因子分析进行结构有效性验证，通过将项目分为态度的三个类别（认知、情感和行为）进行内容有效性验证。数据于 2008 年 5 月至 11 月收集。
问卷在 219 名西班牙社区护士中进行了验证，他们的平均年龄为 43.21（SD 10.3）岁，64.5%（141 人）为女性。共有 54.3%（121 人）在社区工作超过 10 年。问卷由 15 个项目组成，分为构成态度概念的三个因素。整个问卷的 Cronbach's alpha 为 0.853。因子分析解释了 54.70%的方差。
EBNAQ 简洁，使用方便。它是第一个专门用于衡量社区护士对 EBN 态度的西班牙语问卷。EBNAQ 可在研究和实践环境中有效使用，以更好地了解护士对循证实践的态度。
