Abstract

Background: To date, there is no specific instrument to measure evidence-based practice (EBP) in Speech and Language Pathology (SLP). Therefore, it is essential to design a valid and reliable instrument in the EBP field for SLP. Aim: To develop a speech and language pathology evidence-based practice questionnaire (SLP-EBPQ) for the Iranian context and evaluate its psychometric properties. Method: This study was performed in two stages, first development of the instrument based on the literature review and semi-structured interviews with 14 speech and language pathologists and second the evaluation of the psychometric properties. Content validity of the instrument was assessed by SLP experts who were experienced in the field of EBP. Furthermore, exploratory factor analysis (EFA) and comparison of the recognized groups were conducted to determine the initial construct validity of the SLP-EBPQ. The reliability of the questionnaire was determined using internal consistency and test-retest reliability. A total of 280 speech and language pathologists completed SLP-EBPQ to evaluate construct validity and internal consistency. Furthermore, 30 speech and language pathologists completed the SLP-EBPQ after 2 weeks for test-retest reliability. Results: The developed instrument was a questionnaire with 77 items. The results of EFA demonstrated that the SLP-EBPQ contained nine factors with appropriate internal consistency (α=0.635-0.885). Moreover, the Intra-class Correlation coefficient of the factors was (r=0.814-0.966) in the test-retest reliability. Implications for Practice: The SLP-EBPQ is a valid and reliable instrument and can be applied to evaluate EBP among speech and language pathologists for educational, clinical, or research purposes.

语言病理循证实践问卷(SLP-EBPQ)的编制与心理测量评价

背景:迄今为止，在言语和语言病理学(SLP)中还没有特定的工具来衡量循证实践(EBP)。因此，设计一种有效、可靠的EBP测量仪器是至关重要的。目的:为伊朗语境设计一份基于证据的言语和语言病理实践问卷(SLP-EBPQ)，并评估其心理测量特性。方法:本研究分两个阶段进行，第一阶段是基于文献综述和对14名言语和语言病理学家的半结构化访谈开发工具，第二阶段是对心理测量特性的评估。仪器的内容效度由在EBP领域经验丰富的SLP专家进行评估。此外，通过探索性因子分析(EFA)和识别组的比较来确定SLP-EBPQ的初始构念效度。问卷的信度采用内部一致性和重测信度来确定。共有280名语音和语言病理学家完成了SLP-EBPQ来评估构念效度和内部一致性。此外，30名言语和语言病理学家在2周后完成了SLP-EBPQ的重测信度。结果:所研制的仪器为问卷，共77项。EFA结果表明，SLP-EBPQ包含9个因子，内部一致性较好(α=0.635 ~ 0.885)。在重测信度中，各因子的类内相关系数为(r=0.814-0.966)。实践意义:SLP-EBPQ是一种有效和可靠的工具，可用于评估语言和语言病理学家的EBP，用于教育，临床或研究目的。

期刊介绍： The Evidence Based Care Journal (EBCJ) is an international, peer reviewed, scientific journal that seeks to promote the development and exchange of knowledge that is directly relevant to all spheres of patient care. The primary aim is to promote a high standard of clinically related scholarship which advances and supports patient care in practice. The Journal also aims to promote the international exchange of ideas and experience that draws from the different cultures in which practice takes place. Further, EBCJ seeks to enrich insight into clinical needs and the implications for patient care intervention and models of service delivery. Emphasis is placed on clinical practicality of research findings and strength of study design. EBCJ is essential reading for anyone involved in healthcare professions, whether clinicians, researchers, educators, managers, policy makers, or students. Contributions are welcomed from other health professionals on issues that have a direct impact on patient care.
