The Omnipotence of Voices II: the Beliefs About Voices Questionnaire (BAVQ)

  • Paul Chadwick (a1) and Max Birchwood (a2)



We describe the development and psychometric investigation of the Beliefs About Voices Questionnaire (BAVQ), a self-report measure of how people understand and respond to their voices. The measure is unique in being driven by and gathering data essential to a cognitive formulation of voices.


Sixty subjects with chronic hallucinatory voices took part.


Psychometric properties of the scales were established, including test-retest reliability (mean = 0.89), internal reliability (mean Cronbach's α = 0.85), and construct validity using factor analysis and the criterion group method.


The BAVQ was found to be easy to complete and the scale may aid clinical assessment of voices, not least because of the possible value of cognitive therapy as a treatment approach.
