What essential component is typically included in a purpose statement for a quantitative nursing research study?

In a quantitative nursing research study, a purpose statement is critical as it outlines the specific aim of the research and clearly identifies the key variables that will be examined. Including key study variables in the purpose statement provides a focused lens through which the research will be viewed and guides the methodology used to explore relationships or outcomes. This clarity on what is being measured helps readers understand the significance of the study and how the results might be interpreted.

The other components listed, while relevant to research, do not belong in the purpose statement itself. Demographics may inform specific aspects of the study but are not essential in the purpose statement. Long-term implications are important considerations but fall outside the immediate scope of what the purpose statement should convey. Research budget and resources are logistical aspects that do not directly relate to the essence of the research question or hypotheses outlined in the purpose statement. The emphasis on key study variables ensures that the research maintains a clear direction and focuses on measurable outcomes, which is fundamental in quantitative studies.
