CONSTRUCT VALIDITY ANALYSIS OF THE GENETICS AND GENOMICS IN NURSING PRACTICE SURVEY: OVERCOMING CHALLENGES IN...

Area of Science:

• Nursing Practice
• Genetics and Genomics
• Psychometrics

Background:

• Assessing the validity of nursing practice surveys is crucial for evidence-based practice.
• The Genetics and Genomics Nursing Practice Survey (GGNPS) requires rigorous evaluation of its psychometric properties.

Purpose of the Study:

• To evaluate the construct validity of the GGNPS.
• To investigate the factorial structure of the GGNPS, accounting for response variations.
• To determine the most appropriate factor model for the GGNPS.

Main Methods:

• Exploratory and confirmatory factor analyses were employed.
• Structural equation modeling (SEM) was used to assess model fit.
• Common methods bias analyses were conducted to evaluate construct validity.

Main Results:

• A 7-factor model demonstrated a slightly better fit (RMSEA = .052) compared to a 5-factor model (RMSEA = .063).
• Fit indices like CFI and TLI did not meet conventional thresholds, indicating structural limitations.
• The survey's response format presented challenges for construct validity assessment.

Conclusions:

• Despite response format challenges, the study supports the theory-based construct validity of the GGNPS.
• Further refinement may be needed to optimize the GGNPS for robust psychometric evaluation.
• The findings contribute to the understanding of genetic and genomics nursing competencies.
