Sample interview questions: How do you ensure the accuracy and validity of self-report measures used in your research?
Sample answer:
Ensuring Accuracy and Validity of Self-Report Measures
1. Use validated scales: Utilize self-report measures that have established psychometric properties, including reliability and validity.
2. Triangulate measures: Collect data from multiple sources (e.g., self-report, behavioral observations, physiological measures) to cross-validate findings.
3. Assess self-awareness: Consider the participants’ level of self-awareness and potential biases. Use measures that account for social desirability or other factors that may influence reporting accuracy.
4. Provide clear and comprehensive instructions: Ensure that participants understand the purpose and format of the self-report measures to minimize misunderstandings.
5. Incorporate validity checks: Include items that assess participants’ willingness to be honest or that provide indications of response validity (e.g., consistency checks).
6. Use multiple items to assess each construct: Enhance reliability by using several items to measure each psychological construct, reducing the potential impact of any single item’s bias or error.
