Attentional Resource Allocation Scale (ARAS)

Background:

Initial analyses of the Attentional Resource Allocation Scale (ARAS) suggested three factors (i.e., imaginative involvement, dissociative amnesia, attentional dissociation).

Psychometrics:

The ARAS has been shown to have acceptable internal consistency in undergraduate (α=.85) and community samples (α=.91; Carleton et al., 2010).

Primary use / Purpose:

The Attentional Resource Allocation Scale (ARAS; Carleton, Abrams, & Asmundson, 2010) is a 15-item measure designed to assess the attention-modifying trait constructs of absorption and dissociation with items ranging from 0 (never) to 4 (always) derived from the DES (Bernstein & Putnam, 1986) and TAS (Tellegen & Atkinson, 1974).
