Limited reporting of psychometric properties for vaping outcome expectancy instruments hinders research. Utilizing the COSMIN guideline can improve the quality of these measures for better vaping interventions.
Area of Science:
- Public Health
- Psychometrics
- Behavioral Science
Background:
- Vaping presents a significant public health challenge, necessitating rigorous research.
- Accurate measurement of vaping outcome expectancies requires psychometrically sound instruments.
Approach:
- This systematic review appraised the psychometric properties of instruments measuring vaping outcome expectancies.
- The review adapted the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline.
- Eleven studies evaluating eight instruments were analyzed based on nine psychometric properties.
Key Points:
- Most studies reported structural validity, construct validity, and internal consistency.
- No studies reported test-retest reliability, measurement error, or responsiveness.
- Commonly assessed subscales included affect regulation, sensory experience, and health consequences.
Conclusions:
- There is a notable lack of comprehensive psychometric testing for vaping outcome expectancy instruments.
- Adopting the COSMIN guideline can enhance the quality and reliability of these measurement tools.
- Improved instruments will support robust research, leading to effective vaping prevention and cessation strategies.
