Assessment of Search Strategies in Literature-Review-Based Candidate Theses Within a Nursing Program.

Background: The majority of candidate theses in baccalaureate nursing programs in Sweden are written as literature studies. Being able to carry out a systematic and structured literature search is an essential part of thesis-related work.

Aim: The aim of the current study was to investigate changes in nursing students' search strategies in candidate theses.

Methods: A retrospective, quantitative study design was obtained. Librarians (n = 2) and teachers (n = 4) randomly examined selected candidate theses (every third thesis, n = 89) from the years 2012, 2014, and 2016.

Results: The result showed a significant improvement over the years (from 2012 and 2014 to 2016) regarding the use of a sufficient number of synonyms, matching search terms to the respective database, use of the Boolean operator OR, and the use of subject headings and free text searches. Use of the title/abstract search largely disappeared. There was a significant change in the types of searches being done. The searches have become more structured in later years as the use of block searches increased significantly; in other words, more systematic and relevant searches have been done in recent years.

Conclusion: The result of this study shows that the quality of the students' search strategies improved significantly during the studied years. It is recommended that search documents are used in both formative and summative assessments to evaluate students' search strategies. Educational development in the form of enhanced collaboration between librarians and teachers in nursing programs is recommended because it might help to develop student search strategies in literature-based candidate theses.
