Single-subject research for nursing practice.

Area of Science:

• Nursing Research
• Clinical Practice
• Research Methodology

Background:

• Clinical nurse specialists (CNS) are integral to advancing nursing knowledge.
• Traditional research methods may not fully capture the nuances of daily clinical practice.
• There is a need for research designs that bridge the gap between clinical interventions and empirical evidence.

Purpose of the Study:

• To advocate for increased utilization of single-subject research designs by CNS.
• To explore the inherent characteristics and challenges of single-subject research.
• To highlight the potential of single-subject designs in enhancing clinical nursing knowledge.

Main Methods:

• Discussion of the core principles and features of single-subject research.
• Exploration of key design considerations including external validity, rigor, and ethical implications.
• Examination of the statistical versus clinical significance in interpreting results.

Main Results:

• Single-subject designs are well-suited for linking process-based nursing practice with research.
• These designs allow for effective utilization of routine clinical observations and interventions.
• Replicated single-subject designs strengthen the evidence base for nursing interventions.

Conclusions:

• Single-subject research is a viable adjunct to existing research methodologies.
• Increased adoption by CNS can significantly contribute to the development of clinical nursing knowledge.
• Addressing concerns regarding single-subject research will facilitate its broader application.
