Structural Validity of the Vineland-3 Parent Caregiver Form

This session is from the NASP 2021 Annual Convention

  • PMD: 1,9
  • Skill Level: Intermediate
  • Session 6: Recent Developments in Assessment and Research

Learner Objectives

This session will help participants…

  1. understand the factor structure behind the Vineland-3.
  2. conceptualize what adaptive behavior is.
  3. be critical consumers of norming data.


When the Vineland-3 was renormed, its factor structure was assumed from the second edition. In this poster, the researchers will share the results of an exploratory factor analysis on the Parent/Caregiver Form from the Vineland-3 to validate the higher-order factor structure. Practitioners will take away a better understanding of the Vineland-3 and its factor structure for adaptive behavior.
