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

OBJECTIVES: 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.

Habitual posture and weekly time spent sitting do not contribute to the lumbopelvic curvature during active unilateral knee extension in sitting test.

[Purpose] To investigate whether habitual pelvic posture and time spent sitting are primary contributing factors to performance in the active unilateral knee extension in sitting test in young people. [Participants and Methods] The participants' ages ranged from 20 to 40 years. LUMOback, a wearable electronic device, was used to measure the proportion of the days spent in a neutral pelvic posture (posture score) and time spent sitting over a week. The lumbopelvic sagittal curvature from T12 to S2 (θ) during the active unilateral knee extension in sitting test was also assessed using a flexible ruler. A multiple regression analysis was performed with the primary independent variables of the posture score and time spent sitting, undertaking priori considerations of potential confounders of sex, and pain condition on the θ value. [Results] Eighty participants (21.7 ± 3.8 years) were enrolled in the study (24 males and 56 females). Neither the posture score nor time spent sitting statistically significantly contributed to the θ value. [Conclusion] Neither the proportion of the day spent with neutral pelvic posture nor time spent sitting detected by LUMOback was the primary contributing factor to the active unilateral knee extension in sitting test performance.
