A Novel Scale to Assess Psychological Strategies in Explosive Ordnance Disposal Technicians


Taylor M, Barczak-Scarboro NE, Hernandez L 99(5). 0 (Journal Article)

Purpose: This report describes the development and validation of the U.S. Navy Explosive Ordnance Disposal (EOD) Combat Mindset Scale-Training (CMS-T), a population-specific measure of psychological strategy use in EOD training environments. Methods: Scale items were developed by a working group composed of active-duty technicians from EOD Training and Evaluation Unit 1, Naval Health Research Center scientists, and a psychometrician. The working group developed 30 candidate items, which were administered to EOD accessions (new recruits), advanced students, and technicians (N = 164). Factor structure was explored with principal axis factoring and Varimax rotation with Kaiser normalization. Internal consistencies were established via Cronbach alpha, and convergent validity was evaluated with correlational and ANOVA models. Results: Five internally stable subscales were derived from 19 essential items, explaining 65% of total variance. The subscales were named relaxation, attentional-emotional control (AEC), goal setting-visualization (GSV), internal dialogue (ID), and automaticity. The most frequently used strategies were GSV and ID. Expected relationships emerged between strategies, most notably AEC and mental health. The scale also differentiated between subgroups. Conclusion: The EOD CMS-T demonstrates a stable factor structure, internal reliability, and convergent validity. This study yields a valid, practical, and easily administered instrument to support EOD training and evaluation.
