Multiple Case-Based Constructivist Grounded Theory

Multiple case-based constructivist grounded theory (CGT) combines Kathy Charmaz's constructivist grounded theory framework with a deliberate multi-case design. The researcher collects and analyzes data from two or more purposively selected cases simultaneously, applying iterative coding, constant comparison, and theoretical sampling across cases to build a grounded theory that accounts for both within-case depth and cross-case variation. The resulting theory is understood as jointly constructed by researcher and participants rather than objectively discovered.
