This open naturalistic study aims to evaluate the efficacy of rTMS in routine practice on auditory resistant hallucinations (AHR) of patients with schizophrenia. To this end, two stimulation methods will be offered to patients: the rTMS stimulation method and the cTBS stimulation method.We principally use the AHRS scale to evaluate the effectiveness of rTMS on RAH in patients with schizophrenia. Our main hypothesis is that rTMS used under naturalistic conditions, in addition to antipsychotics, would allow a relative improvement of resistant auditory hallucinations assessed by the AHRS scale between baseline and end of treatment in patients with schizophrenia.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| The rTMS method | Other | The treatment lasts 2 weeks with 20 rTMS sessions at a rate of 2 sessions per day. Each session lasts 20 minutes with a one hour break between sessions. The application of rTMS will be done on the left temporo-parietal junction. |
|
| The cTBS method | Other | The treatment lasts 15 days with 45 sessions of cTBS at a rate of 3 sessions per day. The session lasts 40 seconds and consists of 3 pulses at 50Hz repeated every 200 milliseconds (5Hz) to reach a total of 600 pulses, with a 15 minute break between sessions. The application of cTBS will be performed on the left temporo-parietal junction. |

The PANSS is a 30 items scale rated from 1 (absent) to 7 (extreme), that assesses psychopathological symptoms observed in patients with psychotic states, particularly schizophrenia. |
| Baseline and at the end of the treatment |
| Cognitive symptoms: Montreal Cognitive Assessment (MOCA), Stroop | The MoCA scale is the most sensitive rapid assessment test and provides the broadest evaluation of cognitive functions (attention, concentration, executive functions, memory, language, visualconstructive abilities, abstraction, calculation, orientation). It tends to replace the MMSE in clinical practice. A score < 26 (25 if cultural level < 3 = primary diploma = CEP) is considered abnormal. The Stroop scale evaluates the capacity for attention and inhibition; thus, it allows to measure the level of interference generated by the automatisms in the accomplishment of a task. The result of the test allows us to see if the person is correctly inhibiting the response (values greater than 0, positive) or if there are significant interference problems (if it is a negative value). | Baseline and 1 month after the end of treatment |
| Addictive attitudes: number of cigarettes/d (tobacco), The Cannabis Abuse Screening Test (CAST), Marijuana Craving Questionnaire (MCQ) | The CAST is a 6-item scale for identifying problematic cannabis use. Each of these items describes use behaviors or problems encountered with cannabis use. The CAST score determines the patient's level of dependence. A score of 1 or less means low risk. A score of 2 means moderate risk. A score of 3 or higher means high risk. The MCQ self-report scale is a questionnaire on marijuana craving. It consists of four constructs or factors that characterize cannabis craving: compulsivity, emotionality, expectancy and determination. A separate score is calculated for each factor. The MCQ can be used to measure cue-induced craving in a research setting or natural craving in cannabis-dependent individuals presenting for treatment. | Baseline and at the end of the treatment |
| Mood: Calgary Depression Scale for Schizophrenia (CDSS) | The CDSS, is designed to assess depression in people with schizophrenia. It takes into account negative symptomatology and possible extrapyramidal effects of neuroleptics. The questionnaire consists of 9 items covering the last 2 weeks. Each item is evaluated on a 4 points Likert scale ranging from : "Absent" (0) to "Severe" (3). The total score is obtained by adding the items and gives a score out of 27. | Baseline and the end of the treatment |
| Quality of life: The Subjective Quality of Life Scale (S-QoL) | The SQoL questionnaire is a self-administered quality of life scale that assesses quality of life in people with schizophrenia from the patient's perspective. The questionnaire has 18 items, each item is rated on a 4 points Likert scale ranging from: "Much less" to "More than desired". Scores range from 0 to 100; higher scores represent better quality of life. | Baseline and end of treatment, also at 1 month and 3 months after the end of the treatment |
| Clinical Global Impressions (CGI) Scale | Clinical Global Impression (CGI) scales are measures of symptom severity, response to treatment, and treatment effectiveness in treatment studies of patients with mental disorders. | Baseline and end of treatment, also at 1 month and 3 months after the end of the treatment |
