title: Evaluation of statistical approaches in quantitative nursing research.
abstract: The purposes of this study were to (a) develop a tool to assess statistical methods and (b) use the tool to evaluate recently published quantitative research. We rated the statistical approaches used in 152 studies published in the 5 top impact-factor nursing research journals from September 2005 to August 2007. Studies were generally of high quality; 45% scored between 80% and 100%, and 22% achieved a score of 100%. Predictors of high scores were interdisciplinary authorship, a statistician coauthor, and the number of aims. The authors conclude that studies published in high impact-factor nursing journals are statistically sound and provide a solid foundation for evidence-based practice.
