A new Researcher Investment Tool (RIT) measures progress for early career clinical and translational researchers (CTR). This validated questionnaire tracks individual research career trajectories, aiding investment impact assessment.
Area of Science:
- Clinical and Translational Research
- Research Career Development
- Psychometrics
Background:
- Significant investments support early career clinical and translational researchers (CTR).
- Lack of tools to measure individual progress along the research continuum.
- Need for consistent measurement of researcher development.
Purpose of the Study:
- Introduce the novel Researcher Investment Tool (RIT).
- Provide a consistent method for measuring individual changes in research career trajectories.
- Assess the psychometric properties of the RIT.
Main Methods:
- Developed a 90-item questionnaire (RIT) with eight domains and four sub-domains.
- Assessed face and content validity.
- Evaluated internal consistency and test-retest reliability.
Main Results:
- Strong content validity and good internal consistency (Cronbach's alpha: 0.85–0.97).
- Stable test-retest reliability (Pearson's correlation: 0.70–0.98).
- The RIT demonstrates robust psychometric properties.
Conclusions:
- The Researcher Investment Tool (RIT) is a novel, validated instrument.
- RIT can consistently measure individual progress in clinical and translational research careers.
- Useful for evaluating the impact of CTR investments on researchers.
