RESUMO
Introduction: In France, advanced practice for psychiatric and mental health nurses has been developing since 2019. The acquisition of clinical skills by advanced practice nursing students requires monitoring and evaluation. This article outlines the process for creating an internship logbook. Objective: To develop and verify a tool for assessing the skills of advanced practice nursing students specializing in psychiatry and mental health during the internship stage. Method: The Delphi method described by Hasson was used, with the aim of obtaining a consensus of over 80% of the experts consulted. Results: A panel of ten experts, all internship tutors at partner healthcare establishments of Aix Marseille University, was consulted twice. The internship logbook was composed of 68 items. Discussion: This tool is the product of a multidisciplinary process including nurses and psychiatric nurses. It can be adapted to a variety of learning environments and helps tutors track the acquisition of clinical skills during the internships, both through external and self-assessment. Conclusion: A new Delphi consultation will foster uptake of this tool. Advanced practice nurses in psychiatry and mental health will be included in the group of experts.

OBJECTIVES: (1) To translate and validate the Epilepsy Anxiety Survey Instrument (EASI) in French people with epilepsy (PWE); (2) to further investigate the screening properties of each dimension of the EASI in terms of Diagnostic and Statistical Manual of Mental Disorders (DSM) anxiety disorders and of epilepsy-specific anxiety disorders, namely, anticipatory anxiety of seizures (AAS) and epileptic social phobia. METHODS: Following back-translation, the French EASI was tested in PWEâ¯>â¯18â¯years using the Mini-International Neuropsychiatric Interview (MINI) as gold standard for DSM anxiety disorders. We added 3 original questions to explore epilepsy-specific anxiety symptoms. The Generalized Anxiety Disorders-7 (GAD-7), Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), and Adverse Events Profile were performed for external validity. Receiver operator characteristics (ROC) were analyzed. RESULTS: One hundred and forty nine native French speakers with epilepsy were included. Concerning DSM disorders, around 25% had GAD, 18% Agoraphobia, and <10% Social Phobia or Panic Disorder. Concerning possible epilepsy-specific anxiety disorder, 35% had AAS and 38% had epileptic social phobia. Bi-dimensional structure of the EASI was confirmed. Internal and external validity was satisfactory. ROC analysis showed AUC of 0.83 for detection of GAD and AUC 0.79 for other DSM anxiety disorders. ROC analysis of the 8-item French brEASI showed good performance for detection of GAD (AUC 0.83) and other DSM anxiety disorders (AUC 0.76) but not for epilepsy-specific anxiety symptoms (AUC 0.63). Conversely, dimension 2 of the French EASI (=10 items) allowed good detection of epilepsy-specific anxiety symptoms (AUC 0.78); cutoffâ¯>â¯4, sensitivity 82.4, specificity 66.7. CONCLUSION: Epilepsy-specific anxiety symptoms were prevalent, in around 60%. The French version of the EASI showed robust performance. The French 8-item brEASI allows screening for all DSM anxiety disorders with superior performance than the GAD-7, but is less suited to screening for epilepsy-specific anxiety. We propose the "Epilepsy-Specific Anxiety" (ESA) 10-item screening instrument, based on dimension 2 of the EASI, as a complementary clinical and research tool.

AIM: This paper describes the characteristics of the new advanced practice nursing roles in France, as well as their challenges and perspectives, and compares the French model with the recommendations of the International Council of Nurses. BACKGROUND: Advanced practice nursing is particularly well established in English-speaking countries. Since 2018, France has become the second French-speaking region to legalize and regulate advanced practice nurses. SOURCE OF EVIDENCE: The International Council of Nurses and French government websites, and scientific databases (PubMed, CINALH, Cochrane Library) were explored. Feedback from French nursing academics was also requested. DISCUSSION: The advanced practice nursing model in France is described according to the scope and conditions of professional practice. The educational program leads to a State diploma with master's degree, which it is mandatory to be a registered nurse. Remuneration depends on the sector of practice in the public hospital, primary care or private sector. Although there is no national strategy for the implementation of advanced practice nursing roles, research projects are being initiated to guide and evaluate the practice. Based on concordance analysis with the recommendations of the International Council of Nurses, the French advanced practice nursing model appears to be similar to the nurse practitioner model. CONCLUSION: Adjustments in the scope of practice and education can be expected as the implementation of these roles is evaluated. IMPLICATIONS FOR NURSING PRACTICE: This is a historical evolution of the nursing profession in France, for which communication with patients and healthcare professionals is essential. IMPLICATIONS FOR NURSING POLICY: The implementation of advanced practice nursing roles in clinical settings requires the development of national strategies to support initiatives and ensure the sustainability of these roles.

This article proposes what we call an "EEG-Copeia" for neurofeedback, like the "Pharmacopeia" for psychopharmacology. This paper proposes to define an "EEG-Copeia" as an organized list of scientifically validated EEG markers, characterized by a specific association with an identified cognitive process, that define a psychophysiological unit of analysis useful for mental or brain disorder evaluation and treatment. A characteristic of EEG neurofeedback for mental and brain disorders is that it targets a EEG markers related to a supposed cognitive process, whereas conventional treatments target clinical manifestations. This could explain why EEG neurofeedback studies encounter difficulty in achieving reproducibility and validation. The present paper suggests that a first step to optimize EEG neurofeedback protocols and future research is to target a valid EEG marker. The specificity of the cognitive skills trained and learned during real time feedback of the EEG marker could be enhanced and both the reliability of neurofeedback training and the therapeutic impact optimized. However, several of the most well-known EEG markers have seldom been applied for neurofeedback. Moreover, we lack a reliable and valid EEG targets library for further RCT to evaluate the efficacy of neurofeedback in mental and brain disorders. With the present manuscript, our aim is to foster dialogues between cognitive neuroscience and EEG neurofeedback according to a psychophysiological perspective. The primary objective of this review was to identify the most robust EEG target. EEG markers linked with one or several clearly identified cognitive-related processes will be identified. The secondary objective was to organize these EEG markers and related cognitive process in a psychophysiological unit of analysis matrix inspired by the Research Domain Criteria (RDoC) project.

BACKGROUND: According to Karl Jaspers, psychopathology requires a comprehensive method, understood as a systematic exploration of the first-person perspective of the patient's experience. At the same time, however, schizophrenia for Jaspers is characterized by its radical incomprehensibility. In addition, Rümke's so-called "praecox feeling" paradoxically combines the incomprehensibility of schizophrenic experience and the evidence of its pathological manifestation in the encounter. AIM: Through a re-examination of the notions of affectivity and interaffective contact we propose a coherent theoretical model to explain the clinician's paradoxical understanding of schizophrenia. METHOD: Phenomenological tradition regards affectivity as an encompassing phenomenon that connects body, self, world, and others. In our view, only a thorough and systematic link between corporeity and affectivity is able to explain embodied affective resonance as a basis of empathic comprehension. By drawing on the phenomenology of Marc Richir, we will systematically unfold the complex nature of affectivity and lead it back to a twofold constitution of corporeality. CONCLUSION: The Richirian account on affectivity can be fruitfully put into discussion with other recent phenomenological models on schizophrenia. It might be able to exhibit affectivity as the operative ground of minimal self-disturbance and thus argue for its intersubjective dimension.

BACKGROUND: New determinants of quality of life in schizophrenia need to be identified. As sensory gating deficit is core impairment in schizophrenia, the present study hypothesized that sensory gating deficit is a determinant of impaired quality of life in schizophrenia. This study therefore investigated the relationship between sensory gating deficit and quality of life in patients with schizophrenia after adjusting for key confounding factors. SUBJECTS AND METHODS: Sensory gating was assessed with the auditory event-related potential method by measuring P50 amplitude changes in a double-click conditioning-testing procedure, perceptual impairments related to sensory gating deficit was assessed with the SGI questionnaire and quality of life was assessed with the SQoL 18 questionnaire in 39 patients with schizophrenia. RESULTS: Patients with sensory gating deficit (n=14) had a lower subjective quality of life on the psychological well-being dimension evaluated with SQoL 18 questionnaire (p=0.008) compared to those without it (n=25). This result remained significant (B=-0.45, Wald=4.84, p=0.02) after taking into account 7 potential confounding factors (gender, age, level of education, duration of disorder, positive symptoms, depressive symptoms and anxiety symptoms). Poorer psychological well-being was related to a higher score on the SGI (rho=-0.40, p=0.01), in particular on the Distractibility dimension (rho=-0.47, p=0.001). CONCLUSIONS: These findings suggest that sensory gating deficit may be a determinant of impaired quality of life in schizophrenia. Further studies are needed to address the causal relationship between sensory gating deficit, perceptual impairments, attentional deficit and impaired quality of life in schizophrenia in order to act more efficiently on the quality of life of patients with this disorder.

The aim of the present study was to investigate the effect of second-generation antipsychotics (clozapine or another second-generation antipsychotic) on perceptual abnormalities related to sensory gating deficit. Although clozapine is known to improve sensory gating assessed neurophysiologically, we hypothesized that patients with schizophrenia treated with clozapine would report less perceptual abnormalities related to sensory gating deficit than patients treated with other second-generation antipsychotics do. Forty patients with a diagnosis of schizophrenia were investigated (10 patients treated with clozapine and 30 patients treated with another second-generation antipsychotic drug). Perceptual abnormalities were assessed with the Sensory Gating Inventory. Sensory gating was assessed through electroencephalogram with the auditory event-related potential method by measuring P50 amplitude changes in a dual click conditioning-testing procedure. Patients treated with clozapine present normal sensory gating and report less perceptual abnormalities related to sensory gating than patients treated with other second-generation antipsychotics do. Although the cross-sectional design of this study is limited because causal inferences cannot be clearly concluded, the present study suggests clinical and neurophysiological advantages of clozapine compared with other second-generation antipsychotics and provides a basis for future investigations on the effect of this treatment on perceptual abnormalities related to sensory gating deficit in patients with schizophrenia.

This methodological article proposes a framework for analysing the relationship between cognitive processes and brain activity using variables measured by neurofeedback (NF) carried out by functional Magnetic Resonance Imagery (fMRI NF). Cognitive processes and brain activity variables can be analysed as either the dependant variable or the independent variable. Firstly, we propose two traditional approaches, defined in the article as the "neuropsychological" approach (NP) and the "psychophysiology" approach (PP), to extract dependent and independent variables in NF protocols. Secondly, we suggest that NF can be inspired by the style of inquiry used in neurophenomenology. fMRI NF allows participants to experiment with his or her own cognitive processes and their effects on brain region of interest (ROI) activations simultaneously. Thus, we suggest that fMRI NF could be improved by implementing "the elicitation interview method", which allows the investigator to gather relevant verbatim from participants' introspection on subjective experiences.

Perception of environmental sounds from impacted materials (Wood, Metal and Glass) was examined by conducting a categorization experiment. Stimuli consisted of sound continua evoking progressive transitions between material categories. Results highlighted shallower response curves in subjects with schizophrenia than healthy participants, and are discussed in the framework of Signal Detection Theory and in terms of impaired perception of specific timbre features in schizophrenia.

The "Praecox Feeling" (PF) is a classical concept referring to a characteristic feeling of bizarreness experienced by a psychiatrist while encountering a person with schizophrenia. Although the PF used to be considered a core symptom of the schizophrenia spectrum, it fell into disuse since the spread of operationalized diagnostic methods (Diagnostic and Statistical Manual of Mental Disorders/International Classification of Diseases systems). In contemporary research on schizophrenia, it remains largely unaddressed. This critical review investigates the evolution of the PF in historical and contemporary literature and presents an exhaustive overview of empirical evidence on its prevalence in clinical decision making, its reliability and validity. The review demonstrates that the PF is a real determinant of medical decision making in schizophrenia, although, without further research, there is not enough evidence to sustain its rehabilitation as a reliable and valid clinical criterion. PF-like experiences should not be opposed to any criteriological attitude in diagnosis and would be clinically useful if the conditions of descriptive precaution and rigorous epistemology are maintained. The aim of teaching clinical expertise is to transform this basic experience into a well-founded clinical judgment. Finally, the article discusses the possible relevance of the PF for basic science and clinical research according to a translational approach inspired by phenomenology.

Objective: The inability to filter sensory input correctly may impair higher cognitive function in ADHD. However, this relationship remains largely elusive. The objectives of the present study is to investigate the relationship between sensory input processing and cognitive function in adult patients with ADHD. Method: This study investigated the relationship between deficit in sensory gating capacity (P50 amplitude changes in a double-click conditioning-testing paradigm and perceptual abnormalities related to sensory gating deficit with the Sensory Gating Inventory [SGI]) and attentional and executive function (P300 amplitude in an oddball paradigm and attentional and executive performances with a neuropsychological test) in 24 adult patients with ADHD. Results: The lower the sensory gating capacity of the brain and the higher the distractibility related to sensory gating inability that the patients reported, the lower the P300 amplitude. Conclusion: The capacity of the brain to gate the response to irrelevant incoming sensory input may be a fundamental protective mechanism that prevents the flooding of higher brain structures with irrelevant information in adult patients with ADHD.

Someone is called "schizophrenic" when suffering from a disorder described in 1911, for the first time by a Swiss psychiatrist Eugen Bleuler in a book entitled "Dementia Praecox oder Gruppe der Schizophrenien". In this book, Bleuler proposes a two-faced approach: one centered on the disease, the other on the person. Bleuler's main contribution was to show the importance of the latter in the determinism of clinical pictures and illness course, thus opening the way to more anthropological approaches to the schizophrenic self. Taking these approaches into account, at a time when naturalistic models of the illness are prevailing, is far from being of no consequence, as far as the effectiveness of our therapeutic actions is at issue.

Delusion is usually considered in DSM 5 as a false belief based on incorrect inference about external reality, but the issue of delusion raises crucial concerns, especially that of a possible (or absent) continuity between delusional and normal experiences, and the understanding of delusional experience. In the present study, we first aim to consider delusion from a perspectivist angle, according to the Multiple Reality Theory (MRT). In this model inherited from Alfred Schütz and recently addressed by Gallagher, we are not confronting one reality only, but several (such as the reality of everyday life, of imaginary life, of work, of delusion, etc.). In other terms, the MRT states that our own experience is not drawing its meaning from one reality identified as the outer reality but rather from a multiplicity of realities, each with their own logic and style. Two clinical cases illustrate how the Multiple Realities Theory (MRT) may help address the reality of delusion. Everyday reality and the reality of delusion may be articulated under a few conditions, such as compossibility [i.e., Double Book-Keeping (DBK), in Bleulerian terms] or flexibility. There are indeed possible bridges between them. Possible links with neuroscience or psychoanalysis are evoked. As the subject is confronting different realities, so do the objects among and toward which a subject is evolving. We call such objects Hybrid Objects (HO) due to their multiple belonging. They can operate as shifters, i.e., as some functional operators letting one switch from one reality to another. In the final section, we will emphasize how delusion flexibility, as a dynamic interaction between Multiple Realities, may offer psychotherapeutic possibilities within some reality shared with others, entailing relocation of the present subjects in regained access to some flexibility via Multiple Realities and perspectivism.
RESUMO
For years, phenomenological psychiatry has proposed that distortions of the temporal structure of consciousness contribute to the abnormal experiences described before schizophrenia emerges, and may relate to basic disturbances in consciousness of the self. However, considering that temporality refers mainly to an implicit aspect of our relationship with the world, disturbances in the temporal structure of consciousness remain difficult to access. Nonetheless, previous studies have shown a correlation between self disorders and the automatic ability to expect an event in time, suggesting timing is a key issue for the psychopathology of schizophrenia. Timing disorders may represent a target for cognitive remediation, but this requires that disorders can be demonstrated at an individual level. Since cognitive impairments in patients with schizophrenia are discrete, and there is no standardized timing exploration, we focused on timing impairments suggested to be related to self disorders. We present the case report of AF, a 22 year old man suffering from schizophrenia, with no antipsychotic intake. Although AF shows few positive and negative symptoms and has a normal neurocognitive assessment, he shows a high level of disturbance of Minimal Self Disorders (SDs) (assessed with the EASE scale). Moreover, AF has a rare ability to describe his self and time difficulties. An objective assessment of timing ability (variable foreperiod task) confirmed that AF had temporal impairments similar to those previously described in patients, i.e., a preserved ability to distinguish time intervals, but a difficulty to benefit from the passage of time to expect a visual stimulus. He presents additional difficulties in benefitting from temporal cues and adapting to changes in time delays. The impairments were ample enough to yield significant effects with analyses at the individual level. Although causal relationships between subjective and objective impairments cannot be established, the results show that exploring timing deficits at the individual level is possible in patients with schizophrenia. Besides, the results are consistent with hypotheses relating minimal self disorders (SDs) to timing difficulties. They suggest that both subjective and objective timing investigations should be developed further so that their use at an individual level can be generalized in clinical practice.
RESUMO
The severity of depressive symptoms across two discrete mental disorders should be evaluated with the same psychometrically validated tools. In patients with schizophrenia the Calgary Depression Rating Scale (CDSS) is recommended for evaluating depressive symptoms. The aim of this study was to validate the CDSS in patients with major depressive disorder. The CDSS exhibit satisfactory psychometric properties for evaluating depressive symptoms in major depressive disorder. Clinicians and researchers now have a validated scale at their disposal to evaluate depressive symptoms in various mental disorders using a transdiagnostic approach.

BACKGROUND: Previous clinical trials have suggested that repetitive transcranial magnetic stimulation (rTMS) has a significant antidepressant effect in patients with treatment resistant depression (TRD). However, results remain heterogeneous with many patients without effective response. OBJECTIVE: The aim of this SPECT study was to determine before treatment the predictive value of the connectivity of the stimulated area on further rTMS response in patients with TRD. METHODS: Fifty-eight TRD patients performed a brain perfusion SPECT before high frequency rTMS of the left dorsolateral prefrontal cortex (DLPFC). A voxel based-analysis was achieved to compare connectivity of the left DLPFC in responders and non-responders using inter-regional correlations (pâ¯<â¯0.005, corrected for cluster volume). A multiple logistic regression model was thereafter used with the goal of establishing a predictive score. RESULTS: Before rTMS, responders exhibited increased SPECT connectivity between the left DLPFC and the right cerebellum in comparison to non-responders, independently of age, gender, severity of depression, and severity of treatment resistance. The area under the curve for the combination of these two SPECT clusters to predict rTMS response was 0.756 (pâ¯<â¯0.005). CONCLUSIONS: SPECT connectivity of the left DLPFC predicts rTMS response before treatment.

Patients with schizophrenia have difficulty in making sensory predictions, in the time domain, which have been proposed to be related to self-disorders. However experimental evidence is lacking. We examined both voluntary and automatic forms of temporal prediction in 28 patients and 24 matched controls. A visual cue predicted (temporal cue) or not (neutral cue) the time (400 ms/1000 ms) at which a subsequent target was presented. In both patients and controls, RTs were faster for targets presented after long versus short intervals due to the temporal predictability inherent in the elapse of time ("hazard function"). This RT benefit was correlated with scores on the EASE scale, which measures disorders of the self: patients with a high 'self-awareness and presence' score did not show any significant benefit of the hazard function, whereas this ability was preserved in patients with a low score. Moreover, all patients were abnormally sensitive to the presence of "catch" trials (unexpected absence of a target) within a testing block, with RTs actually becoming slower at long versus short intervals. These results indicate fragility in patients' ability to continuously extract temporally predictive information from the elapsing interval. This deficit might contribute to perturbations of the minimal self in patients.

Patients with schizophrenia and people with subclinical psychotic symptoms have difficulties getting a clear and stable representation of their self. The cognitive mechanisms involved in this reduced clarity of self-concept remain poorly understood. The present study examined whether an altered way of thinking or reasoning about one's past may account for the reduced clarity of self-concept in individuals with attenuated psychotic symptoms (APS). An online study comprising 667 participants examined the capacity to give a meaning to past events and to scrutinize autobiographical memory to better understand him/herself. Our results showed that in this sample, individuals with APS (n=49) have a lower clarity of self-concept and a higher tendency to scrutinize autobiographical memory than controls subjects (n=147). A mediation analysis performed on the full sample revealed that the relation between APS and clarity of self-concept was mediated by a tendency to scrutinize autobiographical memory. Our results suggest that the weakness of self-concept, which increases with the intensity of psychotic symptoms, may be related to an altered function of autobiographical memory, so that examining past events may fail to sustain a stable and clear representation of the self when psychotic symptoms increase.
