Purpose: This study aimed to contribute to improving adaptability of the evidence-based practice (EBP) in the clinical and rehabilitation setting, while considering the audiologist’s perception and performance levels of the EBP and the information resources used in the clinical decision-making. Methods: The research conducted a survey on computers or cell phones using the web-based drive provided by Google’s search engine. Eighty audiologists (42 men, 38 women) were participated. Results: The findings were as follows: First, the understanding level for the EBP concept was below average by 2.13 (±1.18) points, and the general perception level for the EBP was average 3.49 (±0.53) points. Influential factors on the perception for the EBP were in the order of final academic background, experience of papers publication, and use of the web-based database (DB). Second, the performance level of the EBP was average by 3.03 (±0.76) points, and the influential factors on the performance level for the EBP were in the order of final academic background, use of the webbased DB, and membership of academy and conference participation. Third, according to the analysis on the multiple responses to the information resources used in the clinical decision-making, the responses were in the order of colleague’s advice (18.0%), text books (16.7%), and my own clinical experience (13.1%). Conclusion: This study concluded that the audiologists positively recognized the EBP and the performance level for the EBP was less than the perception level. It is necessary to preferentially provide the opportunities of education experience on the EBP and continuously provide education on the EBP application methods.
