Escala de Aceitação e Ação para as VozesGeneral Description
The VAAS was developed to assess acceptance-based or action-based beliefs in response to auditory verbal hallucinations, in general and specifically to command hallucinations. This 31-item scale is divided into section A (i.e., 12 item stand-alone scale for general auditory hallucinations) and section B, referring specifically to command hallucinations. The participant is asked to rate their opinion from 1 ‘Strongly Disagree’ to 5 ‘Strongly Agree’, with higher scores meaning higher levels of acceptance and perception of acting according to one’s valued life directions.
