Caitlin Clark Defends Dissertation

Success-Coffee
Caitlin Clark successfully defended her dissertation on Monday. She completed a complex and time-consuming instrument development project, starting with running focus groups for item generation, moving through exploratory factor analysis with one sample, and culminating in a confirmatory factor analysis and validation study with another sample.

In spite of the increased interest received by relational aggression among emerging adults, the lack of psychometrically sound measures appropriate for this age range continues to be an important barrier. Caitlin’s dissertation, Validation of the Young Adult Relational Aggression Scale (YARAS), attempted to confirm the hypothesized factor structure of a new measure as well as assess its reliability and validity in a college student sample.

Although she was able to identify a suitable factor structure, doing so required her to correlate several items and meant that the predicted structure could not technically be confirmed (i.e., the confirmatory procedures became exploratory). Nevertheless, we learned a great deal about the construct and the new measure that should inform future work aimed at refining the measure.

Congratulations to Caitlin on completing this important milestone!

Caitlin is currently completing her predoctoral internship at the Bay Pines VA Healthcare System in Florida and has accepted a postdoctoral fellowship next year at the Michael E. DeBakey VA Medical Center in Houston.
