An Exploration of the Reliability and Validity of the Spanish Version of the 'Voice and You' (VAY): A Scale for Measuring the Relationship with Voices.

Abstract

The purpose of this study was to adapt the 'Voice and You' Scale (VAY) (Hayward, Denney, Vaughan, & Fowler, 2008) to Spanish and explore its psychometric properties for measuring the perceived relationship with voices. A sample of 50 psychiatric patients with verbal auditory hallucinations (48 had a psychotic disorder and two a borderline personality disorder) was used. Its reliability was calculated using the Cronbach's α and test-retest, and concurrent validity by the Pearson correlation coefficient of the VAY with the Beliefs About Voices Questionnaire and the Psychotic Symptom Rating Scales. The results showed that internal consistency of the Spanish version of the VAY ranged from 0.74 to 0.84 on the various subscales, and test-retest reliability varied from 0.74 to 0.83 on three subscales (voice 'dominance', 'intrusiveness' and hearer 'dependence'), and was lower (0.68) on the hearer 'distance' subscale. Concurrent validity was acceptable as significant associations were found with the Beliefs About Voices Questionnaire and the Psychotic Symptom Rating Scales subscales. It is concluded that the Spanish version of the VAY is a reliable and valid instrument that can assist the exploration of voices within relational frameworks across research and clinical domains. The Spanish version of the VAY is a reliable, valid instrument for evaluating the perception a person can have about his or her relationship with the voices and how the person relates to them. Voices that are perceived as relating dominantly and intrusively, and from whom distance is sought, seem to be distressing and cause disturbance. Voices that are related to dependently are perceived as having benevolent intent and are engaged with. Benevolent or neutral voices may be considered as intrusive because of the intensity and frequency with which they are experienced.
