Originally viewed as a psychiatric cognitive deficit, dissociation has been suggested to be normative and even adaptive in certain instances in non-clinical populations. This study aims to optimize the Dissociative Ability Scale (DAS), a novel self-report instrument to measure the ability to experience normative dissociation. To bolster the model fit, internal consistency, and factor structure of the DAS we conducted an internet-based survey (N=833) aiming to guide scale optimization by item-pruning based on sequential exploratory factor analysis. The results indicated that a 7 item, two factor structure is optimal, producing good model fit and excellent internal consistency. The factors were re-named Ability to Focus Attention (FA) and Ability of Vivid Imagination (VI). Further investigation is suggested to confirm the validity and internal consistency of the new structure in additional normative samples. With subsequent confirmatory research, the DAS may be the first reliable and valid scale to measure non-pathological dissociative ability.
