The Efficacy of Speech Competition Training on Auditory Hallucination in Schizophrenia
Study Details
Study Description
Brief Summary
One hundred schizophrenia patients with auditory hallucinations will be recruited and randomized into group A and group B. Participants of group A will firstly receive a speech competition training for 2 weeks, and those in group B will firstly receive music intervention as placebo treatment. Specifically, speech competition training include voice competition training twice a day in adjunction with drug treatment, and the patients will be required to perform voice-related tasks according to the instruction. The reaction time, accuracy rate and the number of auditory hallucinations during the task will be recorded. On the other hand, the placebo treatment includes soothing music twice a day for a fixed period of time while patients receiving drug treatment. After 2 weeks, the interventions for group A and group B will be switch.
Clinical symptoms will be evaluated using the auditory hallucinations rating scale, positive and negative syndrome scale, belief about voices questionnaire-revised at baseline, 2-week follow up and 4-week follow up. All the data will be analyzed with the Statistical Product and Service Solutions(SPSS) software.

Outcome Measures
Primary Outcome Measures
- Auditory Hallucinations Rating Scale (AHRS) [Change of AHRS score from baseline at 2 weeks and 4 weeks respectively]
The Hoffman Hallucination Rating Scale (AHRS) is a clinical tool used to assess the severity of auditory hallucinations in patients. In current study, the scale is used to evaluate the severity of auditory hallucinations in patients with schizophrenia, mainly from seven aspects: frequency, authenticity, loudness, number of sounds, duration, attention significance, and pain level.
- Belief About Voices Questionnaire-Revised (BAVQ-R) [Change of BAVQ-R score from baseline at 2 weeks and 4 weeks respectively]
This scale is a self-assessment scale developed by Chadwick et al., used to measure the beliefs, emotions, and behaviors of patients with auditory hallucinations, with a total of 35 items. Straus et al. reconducted factor analysis on its basis and extracted four factors, namely victim belief (authority belief+malicious belief), goodwill belief, participation in auditory hallucinations, and resistance to auditory hallucinations. The scale items are scored using the Likert 4-level scoring method, with a score of 0-3 and independent scores for each dimension.
Secondary Outcome Measures
- Negative and Negative Syndrome Scale (PANSS) [Change of PANSS score from baseline at 2 weeks and 4 weeks respectively]
The Negative and Positive Symptoms Scale is a widely used scale for assessing patients' clinical symptoms. The PANSS scale has a total of 30 items, including three subscales of positive symptoms, negative symptoms and general psychopathological symptoms. Each item is scored 1-7 in increasing order of severity. The sum of the items contained in the factor is the factor score, and the scores of all items are added to obtain the total score.
