Thesis advisor: Ann W. Burgess / Purpose: The purpose of this descriptive phenomenological study was to understand the lived experience of Black emerging adults with psychotic disorders who have community violence exposure (CVE). The aims included understanding how Black emerging adults with psychotic disorders described the experience of community violence in their lives. A secondary aim was to understand how these individuals described how their experience of community violence has impacted their ability to attain goals that are consistent with emerging adulthood.Background: CVE is a public health crisis. Black emerging adults are at an increased risk of CVE and having a psychotic disorder. CVE and psychotic disorders can cause an increased burden on life. While there is research examining the impact of CVE on mental health and research examining the effects of trauma on psychotic disorders, there is limited qualitative work in Black emerging adults with psychotic disorders and CVE. Method: This study was guided by Husserl's descriptive phenomenology philosophy, and Giorgi's descriptive psychological phenomenological approach guided data collection and analysis. Eleven participants were recruited through purposive sampling. Participants had to have a psychotic disorder, report CVE, identify as Black or African-American, and be between 18 and 29. Interviews were conducted individually with each participant to understand their experiences of CVE. Using bracketing, the data was coded and analyzed. Rigor and trustworthiness were ensured by using Lincoln and Guba's criteria for credibility, confirmability, dependability, and transferability. Results: The sample consisted of eleven participants, ranging in age from 21 to 28, with an average age of 24.6. Six identified as male, four identified as female, and one participant identified as transgender and non-binary/non-conforming. All participants identified as non-Hispanic Black/African-American and had a primary psychotic disorder. Four themes were identified: (1) CVE results in a range of emotional responses, (2) CVE results in a range of behavioral responses, (3) CVE causes disruptions in life and relationships, and (4) participants aspire for a better life without a clear pathway. These four themes represent the lived experiences of CVE in these Black emerging adults who have psychotic disorders in Boston, MA. The themes shed light on the consequences CVE had in their lives. Conclusion: Utilizing descriptive phenomenology created a comprehensive understanding of the experience of the phenomenon of CVE in Black emerging adults with a psychotic disorder. The results illuminated the complex nature CVE has on their life and mental health. Future research should focus on quantitative studies to explore the impact of CVE on various health, social, and psychological outcomes. / Thesis (PhD) — Boston College, 2024. / Submitted to: Boston College.

Bakgrund: Tidigare forskning visar att patienter med psykossjukdomar får ett negativt bemötande i den somatiska slutenvården. Sjuksköterskors fördomar och bristande kunskap är något som kan inverka på omvårdnaden, en inställning som präglar samhället i stort både i nutid och historiskt sett. Förutsättningar för en personcentrerad omvårdnad innebär en relation av tillit och trygghet något som sjuksköterskor ofta saknar kunskap och erfarenhet att tillgodose i mötet med patienter med psykossjukdomar. Syfte: Att ur ett sjuksköterskeperspektiv beskriva upplevelser av att bemöta patienter med psykossjukdom inom den somatiska slutenvården. Metod: En litteraturöversikt har gjorts för att belysa hur sjuksköterskor upplever bemötandet av patienter med psykossjukdom inom den somatiska slutenvården. Resultatet baserar sig på tolv vetenskapliga artiklar varav sju var kvalitativa och fem kvantitativa vilka analyserades enligt Fribergs (2012) metod för resultatanalys. Resultat: Resultatet tyder på att sjuksköterskor upplever brister i kunskap, erfarenhet, stöd och tid. Negativa inställningar som frustration och rädsla är vanligt förekommande. Slutsats: Sjuksköterskor efterlyser en vidare utbildning i psykiatrisk omvårdnad för att undanröja negativa attityder i bemötandet av patienter med psykossjukdomar. Även tidsbrist upplevs som ett betydande problem i omvårdnaden. / Background: Previous research shows that patients with psychotic illnesses receive a negative attitude in somatic inpatient care. Nurses´ prejudices and lack of knowledge is something that can affect the care. This attitude characterizes society in general, both today and historically. Preconditions for a person-centered care implies a relationship of trust and confidence. Nurses often lack the knowledge and experience to accommodate in the meeting with patients with psychotic illnesses. Objectives: From a nurse perspective describe nurses’ experiences of encounters with patients with psychotic illness in somatic inpatient care. Methods: A literature review was used to highlight nurses' perceived treatment of patients with psychotic illness in somatic inpatient care. The results are based on the twelve peer-reviewed articles, seven were qualitative and five were quantitative, these were analyzed according to Friberg (2012) method for analysis of results. Results: The results show that nurses are experiencing gaps in knowledge, experience, support and time. Negative attitudes such as frustration and fear are common. Conclusions: Nurses request increased education in psychiatric nursing to eliminate the negative attitudes in treatment of patients with psychotic illnesses. Lack of time is also considered to be a significant problem in nursing.

>Magister Scientiae - MSc / INTRODUCTION: Sustained attention is known to be dysfunctional in psychotic disorders. Sustained attention is the ability to remain focused on a specific time-locked stimulus within a task. We aimed to determine whether there are specific group differences between CON and three psychotic disorders: SCZ, MPD and BPD, then to determine differences between these psychotic disorders. This included differences in behavioural performance and prominent electrophysiological event-related potential (ERP) wave components during cueing and target processing of a visual sustained attention task. Further we aimed to characterize ERP waveform component relationships across and within these groups for demographics, substance use, behavioural performance, and clinical variables, the last limited to the psychotic groups. Lastly, we investigated the effects of prescribed medications on ERP wave components within the psychotic groups. METHODOLOGY: 103 participants (29 schizophrenia (SCZ), 28 bipolar disorder with a history of psychosis (BPD), 21 methamphetamine-induced psychotic disorder (MPD), and 30 controls (CON)) underwent electroencephalography (EEG) record while completing a visual continuous performance task. Participants were presented with 60 trials with three consecutive S’s, the presentation of the third S required a behavioural response. Prominent ERP waveform components were extracted from cues and target stimulus. Group differences were determined by ANOVA with Bonferroni post-hoc correction or multivariate Kruskal-Wallis test dependent on data distribution. Relationships between ERP wave components were determined appropriate with Spearman’s Rank order correlation analyses. RESULTS: (1) MPD reported higher use of substances compared to CON, SCZ and BPD. SCZ behavioural performance was poorer compared to CON which was shown by their longer response times, reduced accuracy and increased errors of omission. Clinically, MPD was found to have a shorter duration of illness compared to SCZ. Then SCZ was found to have more positive symptoms compared to BPD whereas BPD had more negative symptoms compared to SCZ. For the first cue, wave component differences were found only over the left hemisphere, for P100 amplitude over the frontal cortex, P300 amplitude over the central cortex, and N170 amplitude over the parietal cortex. For the presentation of the second cue, differences noted for all groups were localised to the frontal and central brain regions, for P100 and N170 ERP waveforms. For the target stimulus wave component differences were found over the prefrontal, frontal and parietal brain regions, within CON, SCZ, BPD and MPD. (2) For the first cue, education positively correlated with the N170 left parietal amplitude in CON and P300 right parietal amplitude in MPD. During the second cue, the left parietal N170 latency in SCZ correlated positively with education and the left central P300 latency correlated negatively with education in MPD. The age on the day of testing correlated positively with the target left frontal P300 latency in MPD. For the first cue, substance use positively correlated with the left and right parietal P300 latency and negatively for the right parietal P100 amplitude in SCZ. In MPD, a negative correlation was noted across left and right prefrontal N170 and P300 amplitudes, and positive correlation for the left prefrontal P300 latency in MPD. For the target stimulus, correlations were evident for the left and right parietal N70, N170 amplitudes, P300 latency, the right parietal P100 amplitude and left central P300 latency in SCZ. For the first cue, in SCZ PANSS total score correlated positively with left and right central P300 amplitudes and the left parietal P300 amplitude. For the second cue; in MPD, the PANSS negative symptom score, positively correlated with the P100 and N170 left parietal amplitude, left and right parietal P150 amplitude, left central and right parietal P300 amplitude. For the target, the Hamilton depression rating scale correlated positively with the left and right frontal P300 amplitude in MPD and then negatively with the right parietal P300 amplitude in SCZ. Behavioural performance in CON, positively correlated with the left parietal N70, P100, P150 and N170 amplitude the number of correct responses, and left central N170 amplitude. While the number of impulsive responses correlated negatively with the left parietal N70, P100, P150 and N170 and the left central N170 amplitude of CON. For the second cue, behavioural performance was related to the fronto-parietal relationship across all groups. For the target stimulus, impulsive responses positively correlated with the left parietal N70 latency in SCZ. Overall response time negatively correlated with the right parietal P300 latency for SCZ. (3) Medication was found to affect ERP wave components during the sustained visual attention task. For the first cue FGA’s increased the left central P100 amplitude in both SCZ and BPD and decreased the left parietal P100 amplitude in SCZ only. The use of antipsychotics increased the right parietal N70 and left central P100 amplitudes in BPD, specifically the right prefrontal N170 amplitude was increased with the use of SGA’s. Then clozapine use increased the left frontal P100 amplitude in SCZ. For the second cue, SGA’s decreased the right parietal P150 amplitude in SCZ but in MPD the right parietal P150 amplitude was increased with haloperidol use, and FGA. SGA’s increased the left parietal P300 latency in BPD and sodium valproate decreased the left prefrontal P300 latency. For the target stimulus, SGA’s decreased the right parietal P100, P150 and left parietal P150 amplitudes and increased the left central P300 latency in BPD. CONCLUSION: (1) sustained attentional performance is poorer in SCZ. Our study adds to previous studies showing attention processing deficits in SCZ, are evident during cueing of a sustained attention tasks; (2) substance use was found to slow cognitive processing, education improved executive function and information processing, and symptom severity was associated with dysfunction of prefrontal and frontal cortices; (3) antipsychotic medication was related to improved processing of salient information. These data support the current literature and provide novel insights to the attentional processing deficits during cueing in the psychotic disorders.

Introductions: The aim of the study is to investigate art therapists’ experiences of what is working in the treatment of patients with psychotic disorders.  Issues: What interventions art therapists use in clinical work with patients with psychotic disorders? How is the art therapeutic method significance for the psychotherapeutic treatment?  Method: The study is based on semistructured interviews with five art therapists with experience of treatment with patients in psychotic disorders. The interviews were recorded and then processed using thematic analysis. Result: The result describes five art therapists' experiences of what characterizes the treatment with patients in psychotic disorders. Two main themes emerged in the study with three respectively four subtopic. The interventions applied by the art therapist´s own involvement in the artcreations, it´s supportive interventions ant it´s proposed themes. The other theme is important factors in the treatment; such as visualizing and processing the patients inner experiences, it´s path to verbalization, it´s aid in reality orientation and reliefing effect from psychotic suffering. Discussion: The result is discussed based on the art therapists’ experiences of what is active in the work with patients in psychotic disorders. Interventions and important factors are discussed in relation to different theoretical frameworks of reference. Thoughts on the method are addressed, and that more research is required in the art therapeutic field to consolidate the importance of the method in treatment of patients in psychotic disorders, not least based on requirements for evidence.

A fase inicial dos transtornos psicóticos tem recebido atenção crescente nas últimas décadas, principalmente por tratar-se de um momento de grandes mudanças e perturbações para os indivíduos acometidos e seus familiares. Entre as ferramentas disponíveis para garantir um melhor prognóstico dos indivíduos que vivenciam a fase inicial da psicose destaca-se a intervenção precoce que engloba medidas desenvolvidas com o indivíduo e seus familiares. Para efetivação das propostas de intervenção direcionadas a essa clientela é fundamental o desenvolvimento de estudos de avaliação. Desse modo, o presente estudo tem como objetivo compreender o atendimento familiar individual e o grupo de ação multifamiliar desenvolvidos no Ambulatório de Primeiro Episódio Psicótico (APEP) na perspectiva dos familiares e pacientes. Estudo de abordagem qualitativa a luz do referencial teórico do paradigma da complexidade de Edgar Morin. Participaram do estudo oito díades, pacientes em seguimento no ambulatório de Primeiro Episódio Psicótico do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (APEP/HC-FMRP-USP) e seus familiares que participam de atividades propostas para eles no serviço. Para coleta dos dados foram utilizadas as seguintes questões norteadoras: Você tem tido oportunidade de discutir o que te interessa ou incomoda durante os grupos/atendimentos? Você tem alguma sugestão do que seria interessante conversar e faltou nos grupos/atendimentos? Para você se sentir melhor existe mais alguma coisa que você gostaria de saber? Os dados foram submetidos à análise temática proposta por Braun & Clark. A análise possibilitou a construção de três categorias temáticas e subcategorias: 1) intervenções aos familiares como troca de experiência; 2) envolvimento com as intervenções familiares e 3) reconhecimento do conteúdo abordado nas intervenções familiares. Os resultados reforçam a importância da oferta de intervenções que envolvam pacientes na fase inicial da psicose e seus familiares / The initial phase of psychotic disorders has received increasing attention in the last decades, mainly because it is a time of great changes and disturbances for the affected individuals and their relatives. Among the tools available to guarantee a better prognosis of the individuals who experience the initial phase of psychosis is the early intervention that includes measures developed with the individual and their relatives. The development of evaluation studies is fundamental for the effectiveness of the intervention proposals directed to this clientele. Thus, the present study aims to understand individual family care and the multifamily action group developed in the Psychotic First Episode Outpatient Clinic (APEP) from the perspective of family members and patients. Study of qualitative approach in the light of the theoretical reference of the paradigm of the complexity of Edgar Morin. Participants in the study were eight dyads, patients in the Psychotic First Episode Clinic of the Hospital das Clínicas of the University of São Paulo at Ribeirão Preto Medical School (APEP / HC-FMRP-USP) and their families participating in activities proposed for them in service. The following guiding questions were used to collect the data: Have you had an opportunity to discuss what interests you or bothers you during the groups / services? Do you have any suggestions of what would be interesting to talk about and missed in the groups / services? Do you feel better if there is something else you would like to know? The data were submitted to the thematic analysis proposed by Braun & Clark. The analysis allowed the construction of three thematic categories and subcategories: 1) interventions to family members as an exchange of experience; 2) involvement with family interventions and 3) recognition of the content addressed in family interventions. The results reinforce the importance of offering interventions that involve patients in the initial phase of psychosis and their relatives

O primeiro episódio psicótico (PEP) é um período marcado por uma série de mudanças na dinâmica familiar. A família tem um papel importante no processo de tratamento desses pacientes. As atitudes dos membros familiares acerca do paciente são avaliadas por meio dos níveis de Emoção Expressa (EE) e de sobrecarga familiar. Apesar da importância do papel dos cuidadores, estudos conduzidos para avaliar as relações intrafamiliares de pacientes no PEP são escassos. Este estudo observacional teve como objetivo determinar os fatores relacionados aos níveis de EE e sobrecarga de familiares de pacientes no PEP. Participaram do estudo 100 familiares e 100 pacientes em acompanhamento em um ambulatório de um hospital universitário do interior do Estado de São Paulo, no período de janeiro de 2015 a janeiro de 2016. Para a coleta de dados foram utilizados quatro instrumentos: um formulário contendo dados sociodemográficos e clínicos, o Family Questionnaire - Versão Português do Brasil (FQ-VPB) para avaliar os níveis de EE e de seus domínios Comentários Críticos (CC) e Superenvolvimento Emocional (SEE), o Inventário de Sobrecarga do Cuidador (ISC) para medir os níveis de sobrecarga dos familiares e a Medida de Adesão aos Tratamentos (MAT) para avaliar a adesão ao tratamento. Os dados foram obtidos por meio de entrevista dirigida. Para análise utilizou-se estatística descritiva e regressão logística múltipla. O nível de significância adotado foi de 0,05. Quanto aos resultados, a maioria dos familiares (62%) foi classificada com elevado nível de EE, 63% com baixo nível de CC, 59% com elevado nível de SEE e 43% apresentaram nível moderado de sobrecarga familiar. Em relação à adesão ao tratamento, 84% dos pacientes foram considerados aderentes. Houve associação significante entre os níveis de EE, SEE e o sexo e escolaridade dos familiares, entre o vínculo com o paciente e os níveis de EE, SEE e CC, entre os níveis de sobrecarga e o diagnóstico médico e entre a idade do paciente e os níveis de CC. Além disso, houve associação significante entre os níveis de EE, SEE e CC e os níveis de sobrecarga. A análise do modelo multivariado mostrou que os anos de estudo do familiar foram considerados fatores de proteção para o desenvolvimento de níveis elevados de EE e SEE, enquanto os anos de estudo do paciente foram considerados fatores de proteção para sobrecarga moderada. Outro fator de proteção identificado foi o tipo de vínculo com o paciente, ou seja, ser pai, avós, sobrinhos, primos, tios ou colegas, representa fator de proteção para nível elevado de EE, CC e sobrecarga moderada, moderada a severa e severa. Por outro lado, familiares do sexo feminino apresentaram 4,81 vezes mais chance de apresentar nível elevado de SEE do que familiares do sexo masculino. Além disso, familiares de pacientes com diagnóstico de esquizofrenia tem 4,19 vezes mais chance de apresentar nível elevado de CC do que familiares de pacientes sem diagnóstico. Espera-se que esses resultados possam fornecer informações para elaboração de estratégias de prevenção e promoção em saúde mental que envolvam os pacientes no PEP e seus familiares / The first-episode psychosis (FEP) is a period marked by a series of changes in family dynamics. Family plays an important role in the treatment of these patients. The attitudes of family members about the patient are evaluated by the levels of Expressed Emotion (EE) and family burden. Despite the importance of the role of caregivers, conducted studies to assess the intra-family relationships of patients in the FEP are scarce. This observational study aimed to determine the factors related to EE levels and relatives to FEP patients overwhelmed. The study included 100 families and 100 patients followed up in a clinic of a university hospital in the state of São Paulo, from January 2015 to January 2016. For data collection were used four instruments: a form containing sociodemographic and clinical data; the Family Questionnaire - Brazil\'s Portuguese version (FQ-BPV) to measure the EE levels and its domains of Criticism and emotional overinvolvement (EOI); the Zarit Burden Interview (ZBI) to measure the overload levels of family members and the Measurement of Treatment Adherence (MTA) to evaluate adherence to treatment. The data were obtained by guided interview. For analysis, it was used descriptive statistics and multiple logistic regression. The significance level was 0.05. As the results, most families (62%) were classified with high level of EE, 63% with low criticism, 59% with high level of EOI and 43% had moderate level of family burden. In relation to adherence to treatment, 84% of patients were considered adherent. There was a significant association between EE levels, EOI and the gender and education of family members, between the relationship with the patient and EE levels, EOI and criticism, between the burden levels and the medical diagnosis and between the age of the patient and criticism levels. In addition, there was a significant association between EE levels, EOI and criticism and burden levels. The analysis of the multivariate model showed that the years family study were considered protective factors for the development of high levels of EE and EOI, while the years of patient study were considered protective factors to moderate overwhelm. Another protection factor identified was the type of relationship with the patient. Having another relation with the patient, ie, being a father, grandparents, nephews, cousins, uncles or colleagues, is a protective factor for high level of EE, criticism and moderate overload, moderate to severe and severe. By contrast, female members of the family had 4.81 times more likely to have high level of EOI that those family members who were male. In addition, relatives of patients with schizophrenia has 4.19 times more likely to have high levels of criticism than relatives of patients who do not have diagnosis. It is expected that these results can provide information for developing prevention strategies and promotion on mental health involving patients in the FEP and their families

Esquizofrenia é um transtorno psiquiátrico complexo que afeta cerca de 1% da população mundial. Apesar de progressos consideráveis nos últimos anos, a etiologia da doença ainda não foi elucidada principalmente pela heterogeneidade tanto do início quanto da progressão da doença. Frequentemente os sintomas dos pacientes são comuns a outras desordens neuropsiquiátricas, dificultando a diferenciação por meio de métodos essencialmente clínicos. Por isso, pesquisadores têm tentado identificar medidas baseadas em características moleculares que justifiquem e expliquem a etiologia da esquizofrenia. Já há alguns estudos com marcadores no cérebro, mas por esse ser um material com disponibilidade limitada, os esforços tem se concentrado em encontrar biomarcadores periféricos. Este estudo visou traçar um perfil proteico, em plaquetas, de pacientes drug-naïve com diagnóstico de esquizofrenia. Para tanto, comparamos este grupo com controles saudáveis e com controles psiquiátricos. Utilizamos duas abordagens proteômicas complementares para análise: a primeira, uma ferramenta clássica utilizando eletroforese bidimensional com posterior identificação dos spots por espectrometria de massas; e a segunda, uma abordagem de identificação em larga escala por shotgun label-free. Foram analisadas amostras de 16 controles saudáveis, de 11 pacientes com esquizofrenia e de 8 pacientes com transtornos do humor (controle psiquiátrico). Com a eletroforese bidimensional foram identificados 110 spots comuns nos géis de controles saudáveis, 83 spots comuns aos géis de pacientes com esquizofrenia e 80 spots comuns aos géis de pacientes com diagnóstico de transtornos do humor. Foram encontrados 27 spots exclusivos do grupo controle, não sendo detectados em nenhum dos dois grupos de pacientes. Esses spots foram recortados e analisados por espectrometria de massas revelando proteínas relacionadas com: neurotransmissão, sinapse, neurodesenvolvimento, homeostase celular, sinalização de cálcio, apoptose, resposta imune, e estresse oxidativo. Para verificação dos resultados, escolhemos proteínas de acordo com sua função já descrita na literatura e ineditismo na matriz e na casuística estudadas. Por meio da técnica de western blotting, encontramos diminuições significantes nos níveis de anexina A3 e peroxirredoxina 6 nos dois grupos de pacientes. Ambas proteínas diferentemente expressas nos pacientes já foram relacionadas à fosfolipase A2, que é a principal enzima responsável pelo metabolismo de fosfolípides de membrana e tem sido associada à desordens neuropsiquiátricas, inclusive à esquizofrenia. Ainda há algumas abordagens analíticas e bioinformáticas a serem realizadas na busca por candidatos a biomarcadores de esquizofrenia em plaquetas. Os resultados obtidos por shotgun necessitam de uma análise mais aprofundada além da verificação e validação em coortes maiores. A casuística utilizada para este trabalho é bastante valiosa já que permitirá a elucidação de alterações proteômicas já no primeiro episódio psicótico / Schizophrenia is a mulfatorial psychiatric disorder that affects about 1% of the world\'s population. Despite considerable progress in recent years, the etiology of the disease has not yet been elucidated mainly because the heterogeneity of disease onset and progression. Often the symptoms overlap to other neuropsychiatric disorders, which turns difficult to differentiate through essentially clinical methods. The researchers have focused in identify mesureable molecular characteristics that can help to elucidate schizophrenia etiology. There are already important findings regarding markers in the brain, but recent efforts have focused on finding peripheral biomarkers. This study aimed to find a protein profile in platelets of schizophrenia drug-naïve patients. For comparision we recruited two more groups: healthy controls and psychiatric control. We used two complementary proteomic approaches for analysis: a classic tool using two-dimensional electrophoresis with subsequent identification of the spots by mass spectrometry; and a large-scale label-free shotgun identification approach. The sample comprised 11 schizophrenic patients, 8 patients with mood disorders (psychiatric control and 16 healthy controls. 2-DE profiles of each sample were generated in triplicate. 110 proteins spots were identified in most gels of control group, 83 in most gels of schizophrenia group, and 80 proteins spots in most gels of bipolar disorder patients. Among these proteins spots, 76 were common to all three groups; 5 to controls and schizophrenia group; 2 common to controls and bipolar disorders groups; 2 exclusive of bipolar disorder patients and 27 proteins spots were identified exclusively in the control group. The 27 exclusive protein spots of control group were identified by LC-MS/MS. Proteins related to neurotransmission, synapse, neurodevelopment, cellular homeostasis, calcium signaling, apoptosis, immune response, and oxidative stress were identified. To verify the results, we chose proteins according to their function already described in the literature and novelty in platelets and first onset psychosis patients research. By western blotting we verified the difference in levels of annexin A3 and peroxiredoxin 6 between groups, but not of glutathione S-transferase pi 1 or 78-kDa glucose-regulated protein. Both proteins differentially expressed have already been related to phospholipase A2, which is the main enzyme responsible for the membrane phospholipids metabolism and has been associated with neuropsychiatric disorders, including schizophrenia. Despite the good and promising results presented and published, there are still some analytical and bioinformatic approaches to be performed in search for candidates for platelet schizophrenia biomarkers. The data from shotgun approach require further analysis, as well as verification and validation in larger cohorts. The sample enrroled in this study is greatly important and certainly informed us much about the proteomic alterations still in the first onset psychosis
