Objetivos: Definir o perfil sociodemográfico e a saúde mental em médiuns espíritas,bem como a fenomenologia e o histórico de suas experiências mediúnicas. Métodos: 115 médiuns em atividade foram selecionados aleatoriamente de centros espíritas de São Paulo. Numa primeira etapa foram aplicados os questionários: sociodemográfico e de atividade mediúnica, SRQ (Self-Report Psychiatric Screening Questionnaire) e EAS (Escala de Adequação Social). Todos os médiuns com provável psicopatologia pelo SRQ (n=12) e o mesmo número de controles foram entrevistados com base no DDIS (Dissociative Disorders Interview Schedule), SCAN (Schedules for Clinical Assessment in Neuropsychiatry) e através de uma entrevista qualitativa. Resultados: 76,5% da amostra eram mulheres, idade média 48,1 ± 10,7 anos, 2,7% de desemprego e 46,5% de escolaridade superior. Eram espíritas, em média, há 16,2 ± 12,7 anos e possuíam uma média de 3,5 tipos de mediunidade (incorporação 72%; psicofonia 66%; vidência 63%; audiência 32%; psicografia 23%). Cada modalidade mediúnica era exercitada entre 7 a 14 vezes por semana em média, não havendo diferença entre os sexos. 7,8% dos médiuns ficaram acima do ponto de corte para transtorno psiquiátrico menor pelo SRQ e a amostra alcançou uma pontuação de 1,85 ± 0,33 na EAS. Houve correlação significativa entre os escores de adequação social e de sintomas psiquiátricos pelo SRQ (r= 0,38 p<0,001). Não houve correlação entre a intensidade de atividade mediúnica e os escores SRQ e adequação social. Os médiuns diferiam das características de portadores de transtornos de identidade dissociativa e possuíam uma alta média (4) de sintomas Schneiderianos de primeira ordem para esquizofrenia, mas estes não se relacionaram aos escores do SRQ ou do EAS. Foram identificados quatro grupos de relatos de surgimento da mediunidade: sintomas isolados na infância ou na vida adulta, quadros de oscilação do humor e durante o curso de médiuns. A psicofonia/incorporação possui como pródromos uma sensação de presença, sintomas físicos diversos e sentimentos e sensações não reconhecidos como próprios do indivíduo. Posteriormente, é sentida uma pressão na garganta e mecanicamente começa-se a verbalizar um discurso não planejado. Aintuição foi caracterizada pelo surgimento de pensamentos ou imagens não reconhecidos como próprios. A audição e a vidência se caracterizaram pela percepção de imagens ou vozes no espaço psíquico interno ou objetivo externo. A psicofonia só ocorria no centro espírita, as demais modalidades mediúnicas ocorriam tanto dentro como fora dos centros espíritas Conclusões: Os médiuns estudados evidenciaram alto nível socioeducacional, baixa prevalência de transtornos psiquiátricos menores e razoável adequação social. A mediunidade provavelmente se constitui numa vivência diferente do transtorno de identidade dissociativa. A maioria teve o início de suas manifestações mediúnicas na infância, e estas, atualmente, se caracterizam por vivências de influência ou alucinatórias, que não necessariamente implicam num diagnóstico de esquizofrenia.¶ / Objectives: This study describes the social-demographic profile and psychopathology of Spiritist mediums, history and phenomenology of their mediumistic experiences. Methods: One hundred fifteen actively practicing medium subjects (27 male and 88 female) were randomly selected from different Kardecist Spiritist Centers in the City of Sao Paulo, Brazil. In the early phase of the study, all participants completed social-demographic and mediumistic activity questionnaires, SRQ (Self-Report Psychiatric Screening Questionnaire) and SAS (Social Adjustment Scale). All medium subjects (n = 12) identified by the SRQ with probable psychopathology, and a control group (12 healthy subjects) were submitted to interview using: the DDIS(Dissociative Disorders Interview Schedule), SCAN (Schedules for Clinical Assessment in Neuropsychiatry), and a qualitative interview. Results: Females were 76.5% of the sample, sample mean age was 48.1 ± 10.7 years; 2.7% of the subjects were currently unemployed; and 46% of the sample had a college degree. Participants indicated being Spiritist for an average of 16.2 ±12.7 years, having a mean of 3.5 different types of mediumistic abilities (receiving/embodiment of an spiritual entity 72%; seeing 63%; hearing 32%; and automatic writing 23%). Each mediumistic modality was carried out an average of 7 to 14 times a week with no gender difference; 7.8% of the medium subjects exhibited a minor psychiatric disorder according to the SRQ, and the entire sample scored 1.85 ± 0,33 points in the SAS. There was a significant correlation between social adjustment scores and SRQ psychiatric symptoms (r= 0,38 p<0,001). There was no significant correlation between the degree of mediumistic activity and either SRQ or SAS scores. Medium subjects differed from dissociative identity disorders subjects and displayed 4 Schneiderian first rank symptoms for schizophrenia that were unrelated to either the SRQ or SAS scores. Four distinct modes of emergence of mediumistic symptoms were recorded: isolated symptoms during childhood, isolated symptoms during adulthood, spontaneous mood fluctuations, and formal courses in mediumistic ability development. A full mediumistic trance process begins with: sensing another presence, experiencing a variety of physical symptoms and feelings, and experiencing vibratory frequencies which subjects attributed to an external source, or spiritual entity. Subsequently, subjects begin to feel pressure in the area of the throat and an unplanned speech is mechanically voiced. Intuition is characterized by the emergence of thoughts and/or images not recognized by the subjects as their own. Hearing and seeing are characterized as the awareness of images and voices within the internal psychic space or as an external object. Full mediumistic trance was recorded exclusively within the Spiritist Centers however all other mediumistic experiences were recorded both inside and outside these centers. Conclusions: The medium subjects included in this analysis displayed evidences of having a high social-educational level, a low prevalence rate of minor psychiatric symptoms and a sound level of social adjustment. Mediumistic trance is very possibly an experience other than a Dissociative Identity Disorder. The majority of the subjects experienced the onset of mediumistic experiences during childhood, and the mediumistic process was characterized by experiences of replacement of the ego mind, or visual and/or auditory hallucinations not necessarily related to a definite diagnosis of schizophrenia.

INTRODUÇÃO: As crises não-epilépticas psicogênicas são uma condição médica complexa que pode se apresentar como sintomas físicos ou neurológicos porém sem achados orgânicos correspondentes, evidenciando a presença de fatores psicológicos como base dos sintomas. Elas podem ocorrer isoladamente ou se repetir de forma sistemática. Quando se repetem podem estar associadas à baixa auto-estima, perda de emprego, dificuldade nas relações amorosas e sociais. A esta condição clínica denomina-se transtorno de crises não-epilépticas psicogênicas (TCNEP). Dentre os fatores de risco para TCNEP, os mais amplamente estudados são a história de trauma e os fenômenos dissociativos. MÉTODOS: Neste estudo caso-controle, cujos dados foram obtidos entre janeiro de 2003 e setembro de 2009, foram avaliados 20 pacientes portadores de TCNEP e 20 pacientes com epilepsia do lobo t e m p o r a l , a p ó s m o n i t o r a ç ã o p r o l o n g a d a em u n i d a d e d e vídeo-eletroencefalografia (VEEG). Foram excluídos os sujeitos com associação das duas patologias. Os grupos foram pareados quanto ao gênero, faixa etária, anos de escolaridade formal e classe social. Também foram avaliados: idade de início das crises, idade do diagnóstico, pior frequência de crises e classificação social. Os pacientes responderam também a dois instrumentos estruturados e validados no Brasil, um quanto à história de trauma na infância e adolescência (QUESI), e outro sobre a presença de fenômenos dissociativos (DES) ao longo da vida. RESULTADOS: 1) Não houve diferença significativa do ponto de vista estatístico no que diz respeito ao gênero, faixa etária, classificação social, e frequência de crises; 2) Houve diferença estatisticamente significativa na escolaridade (p=0,006); 3) No grupo caso, a idade de início foi superior (22,25 DP 9,19) à do grupo controle (11,62 DP 9,59), p=0,007. Assim como a idade do diagnóstico, que foi de 30,79 (DP 11,33) no grupo de pacientes com TCNEP e de 15,97 (DP 9,67) nos pacientes com epilepsia, p<0,001; 4) A DES teve valores também estatisticamente significativos, sendo 53,35 (DP 23,15) no grupo com TCNEP e de 22,02 (DP 16,37) no grupo com epilepsia, p<0,001. Quanto às subescalas, todas tiveram resultados significativos entre os grupos; 5) O QUESI apresentou também resultados médios significativos, com média de 60,30 (DP 21,75) no grupo de TCNEP e de 45,40 (DP 12,27) no grupo com epilepsia, p=0,014, mas somente as subescalas que identificaram a negligência e o abuso emocionais foram estatisticamente significativas (p=0,013 e p=0,014 respectivamente). CONCLUSÕES: Fenômenos dissociativos e história de trauma na infância são mais frequentes nos pacientes com TCNEP do que nos pacientes com epilepsia. Todavia, em relação à história de trauma, apenas a negligência e o abuso emocionais podem estar associados à TCNEP / INTRODUCTION: Psychogenic non-epileptic seizures are a complex medical condition that may present as physical or neurologic symptoms but without corresponding organic findings, suggesting the presence of psychological factors as the basis of symptoms. They can occur alone or recur systematically. When recurrent they can be associated with low self-esteem, loss of employment, difficulty in intimate and other social relationships. This clinical condition is called a psychogenic non-epileptic seizures disorder (PNESD). Among the risk factors for PNESD, the most widely studied are the history of trauma and the presence of dissociative phenomena. METHODS: In this case-control study, with data obtained between January 2003 and September 2009, 20 patients with PNESD and 20 patients with temporal lobe epilepsy were evaluated after monitoring in video-electroencephalography unit. We excluded subjects with a combination of both conditions. The groups were matched for gender, age, length of school education and social class. We also evaluated age of onset, age at diagnosis and worse seizure frequency. Patientes of both groups responded two structured instruments for history of trauma in childhood and adolescence (QUESI) and FOR the presence of dissociative phenomena (DES) throughout life, both valitaded in Brazil. RESULTS: 1) There was no statistical significant difference between both groups regard to gender, age, social status and seizure frequency; 2) There was a statistical significant difference in education (p = 0.006); 3) Age of onset and at diagnosis in PNESD group were significantly higher (22.25 SD 9, 19) than the control group (11.62 SD 9.59), p = 0.007, as well as age of diagnosis were higher in patients with PNESD (30.79 SD 11.33) than in patients with epilepsy (15.97 SD 9.67), p <0.001; 4) DES values were also significantly higher in the PNESD group (53.35 SD 23.15) than control group (22.02 SD 16.37), p <0.001. As for the subscales all had significant results between groups; 5) QUESI\'s results were also significantly higher in the PNESD group (60.30 SD 21.75) than in epilepsy group (45.40 SD 12.27), p = 0.014, but only the subscales that identify emotional neglect and emotional abuse were statistical significantly in PNESD group (p = 0.013 and p =0.014 respectively). CONCLUSIONS: History of childhood trauma and dissociative phenomena are more common in patients with PNESD than in patients with epilepsy. However, in relation to history of trauma, only emotional neglect and emotional abuse may be associated with PNESD.

Objetivos: Investigar o perfil sociodemográfico, de experiências anômalas e de saúde mental dos indivíduos que apresentam vivências psicóticas e dissociativas e buscam auxílio em Centros Espíritas; identificar características fenomenológicas, clínicas e sociodemográficas que auxiliem na distinção entre experiência espiritual saudável e transtorno mental. Métodos: Pesquisa longitudinal com um ano de seguimento de 115 sujeitos que apresentavam experiências psicóticas e dissociativas e procuraram Centros Espíritas de Juiz de Fora/MG. Foram utilizadas entrevistas sociodemográficas, de avaliação das experiências anômalas, de critérios propostos para identificar uma experiência espiritual saudável, o SCID (Structured Clinical Interview for DSM-IV Axis I Disorders), o DDIS (Dissociative Disorders Interview Schedule) o DES (Dissociative Experience Scale) e o WHOQOL-bref (World Health Organization Quality of Life-bref). Modelos de regressão logística e linear, controlando para fatores sociodemográficos, foram usados para investigar as associações entre características das experiências anômalas e dissociativas com qualidade de vida e diagnósticos psiquiátricos. Resultados: A amostra foi composta por 70% de mulheres, com idade média de 39 anos e bom grau de instrução, perfil semelhante ao de outros estudos com médiuns espíritas no Brasil. Cinco Critérios Qualitativos da experiência espiritual saudável estiveram presentes na maioria da amostra no primeiro momento da avaliação: ausência de prejuízos sociais e ocupacionais, a experiência ser curta e ocorrer apenas episodicamente, compatibilidade com um contexto cultural, a experiência espiritual trazer benefícios para si mesmo e ser centrada nos outros. Quatro Critérios Qualitativos estavam presentes em uma minoria: ausência de sofrimento, ausência de co-morbidades, atitude crítica e controle sobre a experiência. 93% da amostra apresentavam algum transtorno mental pelo SCID, principalmente quadros ansiosos e depressivos, 23,5% algum transtorno dissociativo pelo DDIS, mas apenas um indivíduo (0,9%) apresentou transtorno de identidade dissociativa. Os escores médios de dissociação foram altos no DES (81,4 ± 54,8 desvio padrão) e no DES TAXON (18,8 ± 16,8). As dimensões de qualidade de vida pelo WHOQOL mais afetadas foram a psicológica (61,15 ± 19,39) e social (63,41 ± 24,07), sendo que a física (67,13 ± 18,25) e a ambiental (63,89 ± 15,05) estavam mais preservadas. Maiores escores de dissociação se relacionaram com mais diagnósticos de transtornos dissociativos e mentais em geral, bem como com menores níveis de qualidade de vida em todas as dimensões. A presença dos Critérios Qualitativos propostos para uma experiência espiritual saudável se relacionou com melhor qualidade de vida nas dimensões psicológica e social tanto no início como após um ano de seguimento. Conclusões: Indivíduos que apresentam experiências psicóticas e dissociativas e buscam auxílio em grupos religiosos são um grupo que necessitam atenção devido ao risco para problemas na saúde mental e qualidade de vida. O potencial efeito protetor do envolvimento religioso e dos critérios qualitativos precisa ser melhor investigado. / Introduction: Spiritual experiences that resemble psychotic and dissociative symptoms are common in several religions, and can bring doubts whether dealing with healthy or pathological experiences. Objectives: Investigating the sociodemographic profile of anomalous experiences and mental health ones of individuals with psychotic and dissociative experiences and seek help in Spiritist Centers; identifying phenomenological, clinical and sociodemographic characteristics which help in distinguishing between healthy spiritual experience and mental disorder. Methods: A Longitudinal Research with one-year follow-up of 115 individuals who have lived psychotic and dissociative experiences and sought Spiritist Centers of Juiz de Fora / MG. We used Sociodemographic interviews, of evaluation of anomalous experiences, and of the proposed criteria for identifying a healthy spiritual experience, the SCID (Structured Clinical Interview for DSM-IV Axis I Disorders), the DDIS (Dissociative Disorders Interview Schedule) DES (Dissociative Experience Scale) and the WHOQOL-BREF (World Health Organization Quality of Life-BREF). Logistic and linear regression model, controlling for sociodemographic factors, were used to investigate associations between characteristics of anomalous and dissociative experiences and quality of life and psychiatric diagnoses. Results: The sample was composed of 70% women, with average age 39 years old and good schooling, profile similar to other studies with Spiritist mediums in Brazil. Five Qualitative Criteria of healthy spiritual experience were present in most of the sample at the first time of evaluation: Absence of social and occupational impairment, the experience is short and occurs only episodically, compatibility with a cultural context, the spiritual experience brings benefits to oneself and it can be focused on others. Four Qualitative Criteria were present in a minority: The absence of suffering, lack of co-morbidities, critical attitude and control over the experience. 93% of the sample had some mental disorder by SCID, mainly anxiety and depression disorders, 23.5% had some dissociative disorder by DDIS, but only one individual (0.9%) had dissociative identity disorder. The average scores of dissociation were high in DES (81.4 ± 54.8 SD) and in DES TAXON (18.8 ± 16.8). The dimensions of quality of life by the WHOQOL which were most affected were the psychological (61.15 ± 19.39) and social (63.41 ± 24.07), and the physical (67.13 ± 18.25) and environmental (63.89 ± 15.05) were better preserved. Higher scores of dissociation were related to more diagnoses of dissociative and mental disorders in general, as well as to lower levels of quality of life in all dimensions. The presence of Qualitative Criteria proposed for a healthy spiritual experience was associated with better quality of life in psychological and social dimensions both at the beginning and and after one-year follow-up. Conclusions: Individuals who have psychotic and dissociative experiences and seek help religious groups are a group that needs attention because of the risk for mental health disorders and quality of life. The potential protective effect of the religious involvement and the qualitative criteria should be further investigated.

L’existence d’un sous-type dissociatif de schizophrénie a été suggérée par plusieurs auteurs pour rendre compte des présentations symptomatologiques d’un groupe de personnes dont le diagnostic principal est dans le spectre de la schizophrénie mais qui présentent aussi des symptômes dissociatifs (Ross, 2004; Şar et al., 2010; Van der Hart, Witztum, & Friedman, 1993). D’origine traumatique, ce type de portrait clinique où symptômes psychotiques et dissociatifs s’entremêlent aurait été décrit il y a déjà plus d’un siècle (Janet & Raymond, 1898) mais serait disparu dans les années ’30, assimilé au concept de « schizophrénie » (Rosenbaum, 1980). C’est dans un nouveau contexte nosographique que le concept de schizophrénie dissociative refait surface. En effet, la nosographie psychiatrique a pris un tournant en 1980 lorsque l’approche préconisée par le DSM est devenue descriptive plutôt que basée sur des conceptualisations psychanalytiques. Du coup, les affections d’alors ont été divisées en troubles dont les symptômes ont tendance à se manifester ensemble (Cooper, 2004) et la comorbidité entre les troubles a augmenté. Étant donné la comorbidité fréquemment rapportée entre les troubles psychotiques et dissociatifs, la similarité phénoménologique de leurs symptômes, ainsi que leur possible étiologie traumatique, Ross (2004) a proposé une série de critères permettant de diagnostiquer une schizophrénie dissociative. L’objectif principal de cette thèse est donc d’établir si la schizophrénie dissociative, telle que définie par Ross (2004), existe. Le premier article porte sur la problématique et le contexte théorique ayant mené à la question de recherche. Il vise à faire un survol des enjeux entourant la question de la schizophrénie dissociative et rend compte des écrits scientifiques sur la symptomatologie similaire entre les troubles psychotiques et dissociatifs, sur leur étiologie traumatique et sur les études sur la dissociation et la schizophrénie. Le deuxième article est quant à lui un article empirique rendant compte de la méthodologie utilisée pour répondre à la question de recherche. En effet, aucune étude jusqu’ici n’a testé systématiquement les critères de la schizophrénie dissociative. Nos résultats démontrent que 24% de notre échantillon (N=50) pourrait recevoir le diagnostic de schizophrénie dissociative avec les critères proposés par Ross (2004). Toutefois, ces critères posant problème, une modification a été proposée et une prévalence de 14% a alors été trouvée. Des vignettes cliniques sont présentées afin de comparer nos participants avec ceux rapportés ailleurs. Les liens entre symptômes psychotiques et dissociatifs sont discutés en essayant de conceptualiser la schizophrénie dissociative de différentes manières, soit comme une nouvelle entité clinique, comme un trouble comorbide ou dans un contexte nosographique psychodynamique. / The existence of a dissociative subtype of schizophrenia has been suggested by several authors to account for the symptomatology of a group of people whose primary diagnosis is in the schizophrenia spectrum but have in addition dissociative symptoms (Ross, 2004; Sar et al, 2010; Van der Hart, Witztum, & Friedman, 1993). Of traumatic origin, this type of clinical picture where psychotic and dissociative symptoms are intertwined was first described more than a century ago (Janet & Raymond, 1898) but disappeared in the 30’s, having been incorporated to the concept of "schizophrenia" (Rosenbaum, 1980). It is in a new nosographic context that the concept of dissociative schizophrenia resurfaced. Indeed, psychiatric nosography took a turn in 1980 when the approach advocated by the DSM became descriptive rather than based on psychoanalytic conceptualizations. The psychiatric conditions of the time were divided into disorders whose symptoms tended to occur together (Cooper, 2004). Consequently, the presence of comorbid disorders increased. Given the frequently reported co-occurrence of psychotic and dissociative disorders, the phenomenological similarity of their symptoms and their potential traumatic etiology, Ross (2004) proposed a criteria set for the diagnosis of dissociative schizophrenia. The main objective of this thesis is to determine whether the dissociative schizophrenia, as defined by Ross (2004), exists. The first article focuses on the problem and the theoretical background that led to the research question. It aims at providing an overview of the issues surrounding the question of dissociative schizophrenia. It also reports on the literature pertaining to symptoms found in both psychotic and dissociative disorders, their traumatic etiology and studies on dissociation and schizophrenia. The second article is of empirical nature and reports the methodology used to answer the research question. Indeed, no study to date has systematically tested the criteria for dissociative schizophrenia. Our results show that 24 % of our sample (N = 50) could receive a diagnosis of schizophrenia with dissociative criteria proposed by Ross (2004). However, the criteria set was problematic so a modification was proposed and a prevalence of 14% was then found. Clinical vignettes are presented to compare our participants with those reported elsewhere. The links between psychotic and dissociative symptoms are discussed in trying to conceptualize dissociative schizophrenia in different ways, either as a new clinical entity, as a comorbid disorder or in a psychodynamic nosographic context.

Nos résultats démontrent que 24% de notre échantillon (N=50) pourrait recevoir le diagnostic de schizophrénie dissociative avec les critères proposés par Ross (2004). Toutefois, ces critères posant problème, une modification a été proposée et une prévalence de 14% a alors été trouvée. Des vignettes cliniques sont présentées afin de comparer nos participants avec ceux rapportés ailleurs. Les liens entre symptômes psychotiques et dissociatifs sont discutés en essayant de conceptualiser la schizophrénie dissociative de différentes manières, soit comme une nouvelle entité clinique, comme un trouble comorbide ou dans un contexte nosographique psychodynamique. / The existence of a dissociative subtype of schizophrenia has been suggested by several authors to account for the symptomatology of a group of people whose primary diagnosis is in the schizophrenia spectrum but have in addition dissociative symptoms (Ross, 2004; Sar et al, 2010; Van der Hart, Witztum, & Friedman, 1993). Of traumatic origin, this type of clinical picture where psychotic and dissociative symptoms are intertwined was first described more than a century ago (Janet & Raymond, 1898) but disappeared in the 30’s, having been incorporated to the concept of "schizophrenia" (Rosenbaum, 1980). It is in a new nosographic context that the concept of dissociative schizophrenia resurfaced. Indeed, psychiatric nosography took a turn in 1980 when the approach advocated by the DSM became descriptive rather than based on psychoanalytic conceptualizations. The psychiatric conditions of the time were divided into disorders whose symptoms tended to occur together (Cooper, 2004). Consequently, the presence of comorbid disorders increased. Given the frequently reported co-occurrence of psychotic and dissociative disorders, the phenomenological similarity of their symptoms and their potential traumatic etiology, Ross (2004) proposed a criteria set for the diagnosis of dissociative schizophrenia. The main objective of this thesis is to determine whether the dissociative schizophrenia, as defined by Ross (2004), exists. The first article focuses on the problem and the theoretical background that led to the research question. It aims at providing an overview of the issues surrounding the question of dissociative schizophrenia. It also reports on the literature pertaining to symptoms found in both psychotic and dissociative disorders, their traumatic etiology and studies on dissociation and schizophrenia. The second article is of empirical nature and reports the methodology used to answer the research question. Indeed, no study to date has systematically tested the criteria for dissociative schizophrenia. Our results show that 24 % of our sample (N = 50) could receive a diagnosis of schizophrenia with dissociative criteria proposed by Ross (2004). However, the criteria set was problematic so a modification was proposed and a prevalence of 14% was then found. Clinical vignettes are presented to compare our participants with those reported elsewhere. The links between psychotic and dissociative symptoms are discussed in trying to conceptualize dissociative schizophrenia in different ways, either as a new clinical entity, as a comorbid disorder or in a psychodynamic nosographic context.

The purpose of this study was to examine forensic social workers' levels of knowledge about skepticism toward Dissociative Identity Disorder (DID) in light of the controversy that surrounds the diagnosis. Relationships between demographic and professional practice variables and workers' levels of knowledge and skepticism were analyzed to assess the possible etiology of skepticism toward DID.
