Decisions about patient care in clinical practice should be made based on proven scientific evidence of efficacy and safety (i.e., evidence-based practice [EBP]). Currently, there are no available tools in Poland for assessing the knowledge and attitudes of specialists in health sciences towards EBP. Therefore, by validating the Polish version of the original English Evidence-Based Practice Profile Questionnaire (EBPQ), we may provide an appropriate instrument for assessing EBP.
The validation group consisted of 1,362 people, including nurses and midwives taking the specialization exam, second-degree students in nursing/midwifery, and staff of selected municipal and clinical hospitals in Warsaw, Pruszkow, and Chelm. The study was conducted from March to June 2014. The following psychometric properties of the EBPQ were assessed: reliability (Cronbach's alpha coefficient, and test-retest), validity (exploratory factor analysis, Spearman's r correlation coefficient, and assessment of inter-group differences), as well as unidimensionality of domains (principal component analysis).
All domains of the EBPQ were characterized by high reliability (Cronbach's alpha ranging from 0.800 to 0.972). The Polish version showed a strong similarity of factor structure with the original English EBPQ, indicating that the condition for theoretical validity is fulfilled. Maintenance of the theoretical and discriminative validity and unidimensionality of five domains of the EBPQ was confirmed.
The Polish version of the EBPQ is comparable in terms of psychometry to the original English version. This questionnaire can be used to assess knowledge, attitudes, and skills concerning EBP among students and practicing professional nurses and midwives. The future validation of the EBPQ in other groups of specialists in health sciences may increase the scope of applicability of this tool.
临床实践中关于患者护理的决策应基于已证实的疗效和安全性科学证据（即循证实践[EBP]）。目前，波兰没有可用于评估健康科学领域专家对循证实践的知识和态度的工具。因此，通过验证原始英文循证实践概况问卷（EBPQ）的波兰语版本，我们可以提供一种评估循证实践的合适工具。
验证组由1362人组成，包括参加专科考试的护士和助产士、护理/助产专业的二年级学生以及华沙、普鲁什科夫和切尔姆选定的市立和临床医院的工作人员。该研究于2014年3月至6月进行。评估了EBPQ的以下心理测量特性：可靠性（克朗巴哈α系数和重测）、有效性（探索性因素分析、斯皮尔曼相关系数以及组间差异评估）以及各领域的单维性（主成分分析）。
EBPQ的所有领域都具有高可靠性（克朗巴哈α系数范围为0.800至0.972）。波兰语版本与原始英文EBPQ的因素结构有很强的相似性，表明满足了理论有效性的条件。证实了EBPQ五个领域的理论和区分有效性以及单维性得以维持。
EBPQ的波兰语版本在心理测量方面与原始英文版本相当。该问卷可用于评估学生以及执业专业护士和助产士关于循证实践的知识、态度和技能。未来在其他健康科学专家群体中对EBPQ进行验证可能会扩大该工具的适用范围。
