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).


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


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




Other Information: 

Imaginative Involvement Subscale: items 1,3 , 8, 9, 10, 12
Dissociative Amnesia Subscale: items 2, 5, 7, 11, 13
Attentional Dissociation Subscale: items 4, 6, 14, 15
Total score is often used, however.
