From: Changes in physiotherapy students’ knowledge and perceptions of EBP from first year to graduation: a mixed methods study

Instrument Domain definitions Number items (maximum score) Psychometric properties
EBP2 domains (5 point Likert scale)
Relevance Value, emphasis and importance placed on EBP 14 items (70) Internal consistency (Cronbach’s alpha 0.96) Test-retest reliability (ICC’s 0.77–0.94 over five domains) Convergent validity for three comparable domains with less comprehensive questionnaire [23] (Pearson correlations: Practice 0.66, Confidence 0.80, Sympathy 0.54) Discriminative validity for EBP exposure (ANOVA p < 0.0001–0.004).
Terminology Understanding of common research and statistical terms 17 items (85)
Sympathy Compatibility of EBP with professional work 7 items (35)
Practice Use of EBP in clinical situations 9 items (45)
Confidence Perception of ability with EBP skills 11 items (55)
K-REC (short answers to clinical scenario, MC, T/F questions)
Actual Knowledge Actual knowledge of EBP 9 items (12) Construct validity (p < 0.0001 comparing scores for EBP exposed and non-exposed participants)
Responsive validity for impact of EBP training (p < 0.001, effect size 1.13)
Test-retest reliability for individual item and total scores
(Cohen’s kappa and ICC range 0.62 to perfect agreement
Inter-rater reliability for individual item and total scores (0.83-perfect agreement)
