Despite increased demands for more and better writing at the graduate level, little is known about graduate-level writing processes or the beliefs of graduate nursing students regarding writing. The goal of the mixed-method research study was to determine the beliefs and writing processes of 100% online graduate nursing students by measuring the writing self-efficacy of these students at the start and the completion of their first online course. A comparative pretest, posttest research design was used for this study. Participant graduate students were enrolled in the first course of an online asynchronous graduate level program of study at an accredited public institution in the southeastern United States. Graduate level students included students who have already been awarded an undergraduate degree and were pursuing a Master’s or Doctoral degree from a degree granting institution. Students were enrolled in a one-hour credit writing course designed to enrich writing skills and review strategies for successful academic writing. Forty-nine students total, eight doctoral program students and forty -one masters’ program students, were invited to participate in the pilot study. The final number of participants was n=29. Data collection began with investigator developed demographic questions. The post-secondary writing self-efficacy instrument (PSWSES) (Schmidt & Alexander, 2012) was administered as both a pre and post assessment method to collect quantitative data. Lastly, in the post-test survey, students were asked to self-report their grades for writing assignments within the courses they just completed. The participants completed a checklist of various of various types of writing assistance to indicate the nature of writing assistance they may have received during the course as well as an opportunity to discuss perceived writing needs for successful degree completion. The Post-Secondary Writing Self-Efficacy (PSWSES) Instrument was administered at the beginning of the course, then again upon conclusion of the course. The results revealed a significant increase in self-efficacy scores with the second administration of the tool. Mean of the 20-question Likert scale pre-test was 70.59. Results obtained after the conclusion of the course resulted in a mean of 80.12. The finding of a mean increase of 9.529 was found to be statistically significant. The presentation will summarize students’ perceptions of their writing self-efficacy before and after the writing course. Additionally, students and faculty were interviewed to evaluate the course and the extent to which the course and program learning outcomes were met. The presenters will share the complete findings of the research including the students’ perception of their writing self –efficacy increased after participation in one credit writing course. The presenters will describe the possible reasons for the changes in the self-efficacy scores after students’ participation in the course. This pilot study demonstrated that writing skills could be improved through guided instruction online.
