Learning evidence-based practice by writing the bachelor's thesis - A prospective cohort study in undergraduate nursing education.

Background: Evidence-based practice has been the desirable healthcare standard for decades. To ensure evidence-based healthcare in the future, nursing education curricula must include strategies for teaching evidence-based practice to nursing students. Learning outcomes about evidence-based practice might be incorporated into courses like the bachelor's thesis.

Aim: This study investigates whether writing a bachelor's thesis influences nursing students' practice, skills, and attitudes towards evidence-based practice, and explores whether there are differences between students writing the thesis as a literature study and students conducting empirical studies.

Design: This Nationwide Prospective Cohort Study collects data on students' practice, skills, and attitudes towards evidence-based practice through the Student Evidence-Based Practice Questionnaire and two questions from the Norwegian version of the Evidence-Based Practice profile questionnaire.

Participants: The sample consists of 314 nursing students writing their bachelor's thesis in the last term of their nursing education. The responding students represent all institutions of higher education in Norway.

Methods: Paired t-tests were used to examine changes in the subscales practice, retrieving/reviewing, sharing/applying, attitudes and total scale for the Student Evidence-Based Practice Questionnaire from before they started to submission of the bachelor's thesis. Linear multiple regression analyses were conducted to explore differences between students writing a literature study and students conducting empirical studies.

Results: The analysis showed that the nursing students significantly increased in the three subscales practice, retrieving/reviewing, and sharing/applying, in addition to the total scale for the questionnaire, while writing the bachelor's thesis. Further, the analysis showed no difference on the scales between the groups of students writing a literature study or conducting an empirical study.

Conclusions: The results indicate that writing the bachelor's thesis leads to increased learning about evidence-based practice and does not depend on the kind of thesis the students write.
