This article is a report of the psychometric testing of the Chinese version of Evidence‐Based Practice Implementation and Beliefs, and Barriers to, and Facilitators of Research Utilization scales. Background. Investigations into the effect of evidence‐based practice on clinical care could be facilitated by instruments for measuring the levels of evidence‐based practice implementation; the strength of beliefs in evidence‐based practice; the barriers to, and the facilitators of research utilization. An English version of the scales measuring the above constructs has been tested whereas the Chinese one has not. Design. Instrument development. Methods. Psychometric analyses of the four evidence‐based scales were conducted on a sample of 361 nurses from a medical centre in Taiwan. Both the internal consistency and squared multiple correlation coefficients were used to examine reliability. The validity testing for the four scales was estimated by examining their construct and concurrent validity. Data were collected between December 2008–January 2009. Findings. Internal consistencies exist for the Chinese Evidence‐Based Practice Implementation, Beliefs, and Barriers to, and Facilitator of Research Utilization scales (≥0·85); some were greater than 0·9, which may indicate redundancy in items. Construct validity of the four scales was supported by hypotheses testing. Concurrent validity of the four scales was supported by known‐group analysis, in which experienced nursing researchers had higher scores compared with clinical nurses. Conclusion. These scales may have value in discrimination between implementation of EBP and perception of barriers to, and facilitators of research utilization among nurses with different education levels, research experiences or working years in clinical setting.

Cultural adaptation and validation of an instrument on barriers for the use of research results

“…The methodological research results on The Barriers Scale were similar to this study concerning the female sex and the age 5 , 7 , 11 - 16 . The habit of reading scientific articles and research development characterized most of the nurses in this study.…”

“…In one study only, in the metric analysis of the Chinese version of The Barriers Scale , the authors used the qualification variable to estimate the construct validity for known groups, affirming that this validity rests on the fact that higher scores were observed among nurses with a higher education level. Nurses holding a Master's degree or higher presented higher mean barrier scores for the use of research results in (x̅=2.91) when compared to nurses holding an undergraduate degree (x̅=2.69; p=0.001) 16 .…”

“…Studies exist in the literature in which the scale was validated for the context of the country 6 - 16 , as well as studies whose authors applied the instrument to identify the barriers for the implementation of evidence in the local practice 17 - 20 .…”

Adaptation and validation of the Evidence‐Based Practice Belief and Implementation scales for French‐speaking Swiss nurses and allied healthcare providers

“…Both scales were originally tested on a sample comprising 394 nurses from five states in the United States who had attended continuing education workshops on EBP in 2005 and 2006 (Melnyk, Fineout‐Overholt, & Mays, ). The EBP‐B and EBP‐I scales have been translated, and their psychometric properties have been evaluated in Chinese (Wang et al., ), Icelandic (Thorsteinsson, ), Norwegian (Stokke, Olsen, Espehaug, & Nortvedt, ) as well as Slovak and Czech (Zeleníková et al., ). The translation processes were rigorous and all showed good psychometric properties, corroborating closely with those of the original versions (Melnyk, Fineout‐Overholt, & Mays, ).…”

Factor Analytical Examination of the Evidence-Based Practice Beliefs Scale: Indications of a Two-Factor Structure

“…Still, the psychometric properties of the EBP-BS have been tested in the U.S. [9] [15], China [16] and Iceland [17], and these studies generally report that the EBP-BS has a well-established construct validity and acceptable internal consistency reliability. Previous research by both Melnyk et al [9] and Thorsteinsson [17] concluded that the EBP-BS had a unidimensional factor structure.…”
