The GPI, developed by Braskamp, Braskamp, and Merril, is anchored by two theoretical perspectives grounded in holistic human development: intercultural maturity (e.g. trying to make sense of their journeys through life) and intercultural communication (e.g. the thinking, feeling, and relating domains). It measures how students think, how they view themselves as people with a cultural heritage, and how they relate to others from other cultures, backgrounds, and values. The instrument identifies three major domains of human development: cognitive, intrapersonal, and interpersonal. This instrument uses a 5-point Likert-type scale.
