Short Answer

A researcher conducts a study and finds a positive correlation between participants' neuroticism scores and the frequency of their self-reported physical pain. Applying the research findings concerning the temporal stability of neuroticism, explain why the researcher would expect to find a similar positive correlation if they reassessed the same participants several years later.

Question: A researcher conducts a study and finds a positive correlation between participants' neuroticism scores and the frequency of their self-reported physical pain. Applying the research findings concerning the temporal stability of neuroticism, explain why the researcher would expect to find a similar positive correlation if they reassessed the same participants several years later.

Sample answer: The researcher would expect to find a similar positive correlation because research indicates that neuroticism remains fairly stable across time. Since the underlying personality trait is stable, its positive correlation with the experience of physical symptoms and pain should also remain consistent when measured again years later.

Key points:

  • Neuroticism is research-proven to remain fairly stable across time.
  • Neuroticism is positively correlated with the experience of physical symptoms and pain.
  • Stability of the underlying trait implies that the observed correlation with physical symptoms will persist over time.

Rubric: To receive full credit, the answer must: 1) Mention that research shows neuroticism remains fairly stable across time. 2) Apply this stability to explain that because the underlying trait remains stable, the positive correlation with physical symptoms/pain is expected to persist in a longitudinal follow-up.
