Cross-cultural Adaptation of the Health Sciences Evidence-based Practice Questionnaire into Japanese and Its Test-Retest Reliability in Undergraduate Students.

Abstract

ABSTRACTObjectives:The Health Sciences Evidence-Based Practice (HS-EBP) questionnaire was recently developed for measuring five constructs of evidence-based clinical practice among Spanish health professionals by applying content and construct validity investigation. The current study aims to undertake a cross-cultural adaptation of the HS-EBP into Japanese and to investigate the internal consistency and test–retest reliability of the Japanese HS-EBP among undergraduate students of nursing and physical and occupational therapies.Methods:Cross-cultural adaptation was undertaken by following Beaton’s five-step process. Subsequently, the Japanese HS-EBP test–retest reliability was assessed with a 2-week interval. Participants were recruited from among third and fourth grade undergraduate students of nursing and physical and occupational therapies with clinical training experience.Results:Pilot testing included 30 participants (11 nursing students, 11 physical therapy students, 8 occupational therapy students). Consequently, we developed the Japanese HS-EBP to be understandable for undergraduate students of nursing and physical and occupational therapies. Data from 52 participants who completed test–retest reliability questionnaires demonstrated adequate test–retest reliability in the total scores of Domains 1, 3, 4, and 5 [intraclass correlation coefficients were (ICC)=0.74, 0.70, 0.75, and 0.74, respectively]; the exception was Domain 2, which had an ICC of 0.66. Internal consistency (Cronbach’s α) was adequate for Domains 1–5, for which α was 0.87, 0.94, 0.86, 0.93, and 0.95, respectively.Conclusions:This study developed the Japanese version of HS-EBP and provided preliminary evidence of adequate internal consistency and test–retest reliability in most domains for undergraduate students of nursing and physical and occupational therapies.
