Instruments measuring evidence-based practice behavior, attitudes, and self-efficacy among healthcare professionals: a systematic review of measurement properties

BACKGROUND: Evidence-based practice (EBP) is well known to most healthcare professionals. Implementing EBP in clinical practice is a complex process that can be challenging and slow. Lack of EBP knowledge, skills, attitudes, self-efficacy, and behavior can be essential barriers that should be measured using valid and reliable instruments for the population in question. Results from previous systematic reviews show that information regarding high-quality instruments that measure EBP attitudes, behavior, and self-efficacy in various healthcare disciplines need to be improved. This systematic review aimed to summarize the measurement properties of existing instruments that measure healthcare professionals’ EBP attitudes, behaviors, and self-efficacy. METHODS: We included studies that reported measurement properties of instruments that measure healthcare professionals’ EBP attitudes, behaviors, and self-efficacy. Medline, Embase, PsycINFO, HaPI, AMED via Ovid, and Cinahl via Ebscohost were searched in October 2020. The search was updated in December 2022. The measurement properties extracted included data on the item development process, content validity, structural validity, internal consistency, reliability, and measurement error. The quality assessment, rating of measurement properties, synthesis, and modified grading of the evidence were conducted in accordance with the COSMIN methodology for systematic reviews. RESULTS: Thirty-four instruments that measure healthcare professionals’ EBP attitudes, behaviors or self-efficacy were identified. Seventeen of the 34 were validated in two or more healthcare disciplines. Nurses were most frequently represented (n = 53). Despite the varying quality of instrument development and content validity studies, most instruments received sufficient ( +) ratings on content validity, with the quality of evidence graded as “very low” in most cases. Structural validity and internal consistency were the measurement properties most often assessed, and reliability and measurement error were most rarely assessed. The quality assessment results and overall rating of these measurement properties varied, but the quality of evidence was generally graded higher for these properties than for content validity. CONCLUSIONS: Based on the summarized results, the constructs, and the population of interest, several instruments can be recommended for use in various healthcare disciplines. However, future studies should strive to use qualitative methods to further develop existing EBP instruments and involve the target population.
