Introduction: An updated summary of the most used instruments assessing auditory hallucinations in population with psychosis, allows us to underline the scarceness and need of Spanish versions of important instruments. The aim of the study is to examine the psychometric characteristics of two different and complementary instruments for assessing auditory hallucinations, the Spanish version of the Auditory Vocal Hallucination Scale (AVHRS) and the Spanish version of the Positive and Useful Voices Inquiry (PUVI).
Materials and methods: A sample of 68 patients from four different centres, with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder presenting with auditory hallucinations were included. Apart from the AVHRS and the PUVI, the Psychotic Symptom Rating Scales-Auditory Hallucinations subscale (PSYRATS-AH) and the Positive and Negative Syndrome Scale (PANSS) were also administered to all patients, plus an acceptability questionnaire.
Results: The Spanish version of the AVHRS showed a good internal consistency, a moderate to high inter-rater reliability, a medium to moderate test-retest reliability, and a good convergent and discriminant validity. The Spanish version of the PUVI showed a good internal consistency and a heterogeneous, but in general moderate, test-retest reliability.
Conclusions: The Spanish versions of the AVHRS and the PUVI have good psychometric properties and are well accepted among patients.
