Studies have shown that in spite of the large number of women within the U.S. who have been the victims of domestic violence, up to 25% of all women, that healthcare providers often do not screen for such activities because they feel as though their actions will not necessarily make a difference and that they do not have enough time or training to do so (Kass-Bartelmes, 2004). To this end it would be possible to create an imaginary quantitative nursing study that uses regressive analysis to determine the preparedness of doctors and nurses within an ER setting to care for women exposed to domestic violence via the use of a questionnaire, similar to the study done by Sundborg, et al. (2012) to determine the preparedness of nurses in dealing with battered women during the course of primary healthcare.
Two methods that may be utilized for selecting variables into a regression equation for the imaginary study are stepwise regression and subset regression. Stepwise regression will allow for the identification of the independent variable that has the greatest correlation to the dependent variable, allowing for a one variable regression to be run, followed by the next unselected variable with the greatest correlation, allowing for a two variable regression to be completed, continuing until such a time as there are no additional variables left (Selecting the Variables for a Regression, 2010). Alternatively, subset regression may be utilized by taking a variety of different subsets of all available independent variables and running models with them until the subset with the best R2 model has been identified (Selecting the Variables for a Regression, 2010).
Regardless of the variable selection process utilized, due to the fact that there is limited research on the subject, the resulting conclusions would become statistically relevant to the field.
