The Phenomenology of inner speech : comparison of schizophrenia patients with auditory verbal hallucinations and healthy controls

Background: Despite the popularity of inner-speech theories of auditory verbal hallucinations (AVHs), little is known about the phenomenological qualities of inner speech in patients with schizophrenia who experience AVHs (Sz-AVHs), or how this compares to inner speech in the non-voice-hearing general population. Method: We asked Sz-AVHs (n=29) and a non-voice-hearing general population sample (n=42) a series of questions about their experiences of hearing voices, if present, and their inner speech. Results: The inner speech reported by patients and controls was found to be almost identical in all respects. Furthermore, phenomenological qualities of AVHs (e.g. second- or third-person voices) did not relate to corresponding qualities in inner speech. Conclusions: No discernable differences were found between the inner speech reported by Sz-AVHs and healthy controls. Implications for inner-speech theories of AVHs are discussed.9 page(s
