A new 10-item Ego Dissolution Scale (EDS) reliably measures trait-like tendencies toward losing one's sense of self and experiencing unity, with internal consistency (Cronbach's α = 0.80) and subfactors for Ego-Loss (α = 0.84) and Unity (α = 0.75). The scale shows strong convergent validity with depersonalization, derealization, mysticism, and unusual experiences, and discriminant validity against neuroticism and social desirability. Ego dissolution and dissociation are empirically related but statistically distinguishable.
