The Research Process

The research process and the nursing process share many similarities, but there are key differences. While the nursing process is focused on providing care at the individual client level, nursing research aims to improve nursing practice at a broader level. The ultimate goal of nursing research is to enhance nursing practice by identifying problems and developing effective solutions. Problem statements in nursing research describe the gap between what is currently known and unknown. One of the first steps in research is developing a research question, which directly precedes selecting a research design. Reviewing existing literature can highlight studies that may be replicated and contribute to answering the research question.

A critical aspect of the research process involves selecting the appropriate research design, which can vary depending on the type of data being collected. Below is a table that outlines different research designs and their corresponding descriptions:

The research process itself follows a systematic sequence of steps:

1. Determine the problem.
2. Review the literature.
3. Design the study.
4. Collect the data.
5. Analyze the data.
6. Communicate the results.
7. Implement practice change.

Additionally, it is important to match the research characteristics to the appropriate research type, such as the objectivity of data in quantitative research or the personal involvement of the researcher in qualitative research.

Types of Research Studies

Research studies can either focus on primary or secondary data collection. Primary data collection is prospective, where data is gathered for the first time. In contrast, retrospective studies use data previously collected for another purpose. When data is collected over a long period, it is called a longitudinal study, whereas a cross-sectional study collects data at a single point in time.

Research questions guide the direction of a study. For example, to assess the effectiveness of a fall prevention intervention, an experimental prospective quantitative study would be appropriate. If exploring obstacles to a pressure ulcer prevention regimen, a qualitative study using focus groups might be the best choice.

Quantitative research is particularly valuable in providing strong evidence for nursing practice, as it enables researchers to make confident inferences about the effectiveness of interventions.

Evidence and Research Design

When reviewing literature, researchers often encounter different types of evidence with varying levels of credibility. For example, clinical practice guidelines are considered the highest level of evidence, followed by systematic reviews, randomized clinical trials, and expert opinions. These sources are ranked in descending order of credibility.

Research studies, especially those that are well-conducted, can guide nursing practice by identifying effective interventions. When analyzing a study, nurses must be vigilant about the validity of its findings, considering factors such as sample size, bias, and potential threats to validity.

PICOT Question and Hypothesis

The PICOT format is commonly used to develop research questions. It consists of the following elements:

• P: Population or problem of interest
• I: Intervention or exposure being studied
• C: Comparison group or intervention
• O: Outcome to be measured
• T: Time frame for the study

A null hypothesis suggests no difference between groups, whereas an alternative hypothesis predicts a significant difference. Identifying the appropriate hypothesis and selecting the correct research design is crucial for answering the research question effectively.

Conclusion

Nursing research plays a vital role in advancing practice and improving patient care. Through systematic inquiry and the use of appropriate research designs, nurses can gather evidence to support interventions and inform clinical decisions. By following the research process and carefully evaluating sources of evidence, nurses ensure that the findings can be applied in practice to improve patient outcomes.
