Psychometric properties of a test in evidence based practice: the Spanish version of the Fresno test
<p>Abstract</p> <p>Background</p> <p>Validated instruments are needed to evaluate the programmatic impact of Evidence Based Practice (EBP) training and to document the competence of individual trainees. This study aimed to translate the Fresno test into Spanish and subsequently validate it, in order to ensure the equivalence of the Spanish version against the original English version.</p> <p>Methods</p> <p>Before and after study performed between October 2007 and June 2008. Three groups of participants: (a) Mentors of family medicine residents (expert group) (n = 56); (b) Family medicine physicians (intermediate experience group) (n = 17); (c) Family medicine residents (novice group) (n = 202); Medical residents attended an EBP course, and two sets of the test were administered before and after the course. The Fresno test is a performance based measure for use in medical education that assesses EBP skills. The outcome measures were: inter-rater and intra-rater reliability, internal consistency, item analyses, construct validity, feasibility of administration, and responsiveness.</p> <p>Results</p> <p>Inter-rater correlations were 0.95 and 0.85 in the pre-test and the post-test respectively. The overall intra-rater reliability was 0.71 and 0.81 in the pre-test and post-test questionnaire, respectively. Cronbach's alpha was 0.88 and 0.77, respectively. 152 residents (75.2%) returned both sets of the questionnaire. The observed effect size for the residents was 1.77 (CI 95%: 1.57-1.95), the standardised response mean was 1.65 (CI 95%:1.47-1.82).</p> <p>Conclusions</p> <p>The Spanish version of the Fresno test is a useful tool in assessing the knowledge and skills of EBP in Spanish-speaking residents of Family Medicine.</p
Effectiveness of a short-course in improving knowledge and skills on evidence-based practice
<p>Abstract</p> <p>Background</p> <p>To assess the effectiveness (change in knowledge and skills measured by the Fresno test) of a short course in Evidence Based Practice (EBP) carried out in a group of family medicine residents</p> <p>Methods</p> <p>Before-after study. Participants' were 152 Family Medicine residents in their second year of the training programme. Settings were Primary Care Teaching Units in Catalonia. Intervention was comprised of a four half-day training course designed to develop the knowledge and skills required to practice evidence-based care. The main outcome measure was change in EBP knowledge and skills, measured using the Spanish version of the Fresno test (score range, 0-212)</p> <p>Results</p> <p>The mean difference between pre-test and post-test was 47.7, a statistically significant result with 95% CI of 42.8-52.5 (<it>p </it>< 0.0001). An important improvement was observed in the questions related to calculations such as sensitivity, specificity, the absolute risk reduction or the number needed to treat. A more modest increase was found in the residents' knowledge and skills in finding the best clinical evidence, and appraising the validity and applicability of an article. Finally, a weak and non-statistically significant improvement was found in formulating a clinical question.</p> <p>Conclusions</p> <p>The study provides evidence for responsiveness to changes in knowledge and skills in EBP after an educational intervention.</p
