Research

DRI is committed to sound research that documents the impact of developmental approaches in individuals and human systems, grounding research in application, and application in research. We also foster the evolution of research models and assessment tools that document the unfolding of awareness in individuals and collectives.

STAGES VALIDATION

Validation Highlights

The STAGES developmental model has been the subject of rigorous validation research. Key findings from the ESRAD 2021 research summary (O’Fallon, Murray et al.):

INTER-RATER RELIABILITY

93%

Item-level accuracy across 5 scorers (98% at survey level)

LONGITUDINAL GROWTH

89%

Of successive assessments showed increase or stability (N=143)

CONVERGENT VALIDITY

Excellent

Cohen’s Kappa vs. SCTi-MAP across 73 inventories, 4 scorers

Investigating the Validity of the Ogive Aggregation Method, Including the Use of Rasch Analysis, for the Sentence Completion Test and the STAGES Model · Tom Murray · Integral Review, Vol. 16, No. 1 (2020)

An examination of the psychometric foundations of STAGES scoring. Using Item Response Theory and Rasch analysis, the paper assesses the limitations of the traditional ogive aggregation method and proposes an alternative approach for measuring adult developmental stages.
