Case Study

Based on the six specific facets that make up the openness to experience construct, evaluate the content validity of the researchers' initial survey draft. What specific facets are being measured, and which specific facets are missing from their operational definition?

Case context: A research team wants to measure the Big Five dimension of 'openness to experience' to see how it correlates with risk-taking behavior in novel situations. To ensure content validity, they design a new self-report survey. Their initial survey draft only includes items asking participants about their appreciation for art and beauty, their vivid imagination, and their tendency to question traditional moral beliefs.

Question: Based on the six specific facets that make up the openness to experience construct, evaluate the content validity of the researchers' initial survey draft. What specific facets are being measured, and which specific facets are missing from their operational definition?

Sample answer: The researchers' draft survey measures aesthetics (appreciation for art), fantasy (imagination), and values (questioning traditional beliefs). However, it is missing items to measure the feelings, actions, and ideas facets. Because it does not capture all six facets of the openness to experience construct, the survey's content validity is limited.

Key points:

  • Identifies that the survey measures aesthetics (art and beauty).
  • Identifies that the survey measures fantasy (vivid imagination).
  • Identifies that the survey measures values (questioning traditional beliefs).
  • Explains that the survey fails to measure the 'feelings', 'actions', and 'ideas' facets.
  • Concludes that content validity is compromised because not all six facets of the overarching construct are represented.

Rubric: Full credit is given for correctly identifying the facets present in the survey and accurately naming the three missing facets required to fully capture the openness to experience construct.
