Icelandic Physical Therapists' Attitudes Toward Adoption of New Knowledge and Evidence-Based Practice: Cross-Sectional Web-Based Survey

Background. A positive attitude toward evidence-based practice (EBP) has been identified as an important factor in the effectiveness of the dissemination and implementation of EBP in real-world settings. Objective. The objectives of this study were: (1) to describe dimensions of Icelandic physical therapists' attitudes toward the adoption of new knowledge and EBP and (2) to explore the association between attitudes and selected personal and environmental factors. Design. This study was a cross-sectional, Web-based survey of the total population of full members of the Icelandic Physiotherapy Association. Methods. The Evidence-Based Practice Attitude Scale (EBPAS) was used to survey attitudes toward EBP; the total EBPAS and its 4 subscales (requirements, appeal, openness, and divergence) were included. Linear regression was used to explore the association between the EBPAS and selected background variables. Results. The response rate was 39.5% (N = 211). The total EBPAS and all of its subscales reflected physical therapists' positive attitudes toward the adoption of new knowledge and EBP. Multivariable analysis revealed that being a woman was associated with more positive attitudes, as measured by the total EBPAS and the requirements, openness, and divergence subscales. Physical therapists with postprofessional education were more positive, as measured by the EBPAS openness subscale, and those working with at least 10 other physical therapists demonstrated more positive attitudes on the total EBPAS and the openness subscale. Limitations. Because this was a cross-sectional survey, no causal inferences can be made, and there may have been unmeasured confounding factors. Potential nonresponse bias limits generalizability. Conclusions. The results expand understanding of the phenomenon of attitudes toward EBP. They reveal potentially modifiable dimensions of attitudes and the associated characteristics of physical therapists and their work environments. The findings encourage investigation of the effectiveness of strategies aimed at influencing various dimensions of attitudes toward EBP.
