What You’ll Learn
- Evidence based practice
- What influnces research?
- Publication bias
Exploring Publication Bias Show Notes
- Nursing school focuses on little research
- Wasn’t until Master that you really learn what to look for and what is good research
- Assumed all evidence based practice is done the same
- Every hosptial does it differently
- All research is not the same
- What infulences research?
- Has to be accepted to be published
- First author came up to study the subject
- Impact factor
- Publication bias
- Reasearch is done based on needs
- What subject can get me published?
- Journals more likely to accept research where findings match the hypothisis
- Positive results
- Journals are filled with more positve results
- This lays groundwork for bias
- See more of something we think that is representaive of the population
- We have to look for the big picture in research
- Publication bias results from the selective publication of studies based on the direction and magnitude of their results-studies without statistical significance (negative studies) are less likely to be published.
- We need those negative results also
- The file drawer problem
- suggests that results not supporting the hypotheses of researchers often go no further than the researchers’ file drawers, leading to a bias in published research
- Doing the same tests over and over until you eventually hit the desired results by chance.
- P-hacking is typically done through manipulation of “researcher degrees of freedom,” or the decisions made by the investigator.
- There is no indication that p-hacking was used
- HARKing is defined as presenting a post hoc hypothesis in one’s research report as if it were, in fact, an a pre hypotheses.
- Citation Bias
- The more times your article has been cited, the more value we place on it
- We cite positive results more often
- Feeding on itself problem
- How are we combating publication bias?
- Publication bias may be reduced by journals publishing high-quality studies regardless of novelty or unexciting results, and by publishing protocols or full-study data sets
- There are grassroots orginizations publishing high quality studies regarless of results
