The aetiology of bipolar disorder remains unclear and investigation to date has focussed largely on bipolar patients. Whilst ultimately of huge value, such studies may also be confounded by current mood or experience of repeated illness episodes or current or past medication; using at-risk samples may bypass some of these problems. The current research therefore assessed the efficacy of the Mood Disorder Questionnaire (MDQ) as a screening tool for vulnerability to bipolar disorder. The MDQ was used with two sets of criteria to identify two sub-groups of medication-naïve young bipolar phenotype subjects who were at risk for bipolar disorder by virtue of experience of mood elevation. Analysis of data from the Student Stress Survey was carried out to characterise the bipolar phenotype. Compared to a control group with no experience of mood elevation, the two bipolar phenotype sub-groups showed a gradient of prevalence of bipolar diagnosis and associated co-morbidity. Behavioural and functional magnetic resonance imaging (fMRI) techniques were employed to investigate emotional processing, decision-making, and sleep and circadian rhythmicity in bipolar phenotype students. Analyses revealed that positive emotional processing biases, disrupted decision-making, and increased activity during sleep were associated with the bipolar phenotype and, therefore, may represent vulnerability markers for bipolar disorder. Finally, a psychopharmacological investigation of quetiapine, which stabilises mood, was carried out in healthy volunteers. One-week quetiapine administration resulted in biases away from both positive and negative emotional stimuli (i.e. a mood-stabilising effect), reduced discrimination between different magnitudes of gains and losses during risky decision-making (consistent with an antidepressant effect), and increased sleep duration. In sum, this research has developed our understanding of vulnerability markers associated with the bipolar phenotype and provided a first step towards uncovering the psychological mechanisms through which quetiapine’s clinical effects may be mediated.

Bipolar mood disorder has been traditionally researched, explored, and explained from a modernistic, psychiatric perspective. The purpose of this study is to explicate an alternative description for bipolar mood disorder, from a postmodern perspective. The widely accepted psychiatric knowledge focuses on the signs and symptoms of the disorder, pharmacological treatments, and manualised psychotherapies. This thesis shifts the focus from an intrapsychic, deficit perspective towards one which is inclusive of surrounding discourses and patterned relationships. The social constructionist research approach is followed, utilising vignette and thematic analyses for textual deconstruction and reconstruction. In addition to these data analyses, discourses were analysed using the actual text of the co-researchers. This allowed for a thorough explication of the ways in which discourses shape the construct bipolar mood disorder. From these analyses, emergent themes were then distilled and compared to the existing body of literature in the bipolar mood spectrum field of study. Process models were generated to depict the various pertinent aspects of the social construction of bipolar mood disorder. This research has value for the treating professional, allowing for a broader, more inclusive discourse perspective to add to the already established medical model view. Further, this research gives credence to the voice of the person who has been diagnosed with the illness. This research may also contribute to the epistemological debates within modernist and postmodernist paradigms. Key words: Bipolar mood disorder, medical model, pharmacology, mania, depression, psychiatry, psychotherapy, titrating power relations, expert, problem determined systems, belonging, problems of therapy and therapeutic problems, vignette analysis, people as meaning generating beings, context, reflexivity, self-reflection, multiple realities, positivism, social constructionist epistemology, qualitative research, process model. / Psychology / D.

Embora fatores psicológicos tenham sido inicialmente considerados participantes da etiologia da DC, esta hipótese foi descartada. Apesar de existirem evidências crescentes de que sintomas depressivos e ansiosos são muito frequentes em pacientes com DC, poucos dados a cerca da oscilação destes sintomas psicológicos durante o curso clínico da doença, particularmente em suas fases de remissão e recidiva estão disponíveis. Os objetivos deste estudo foram avaliar em pacientes portadores de DC a possível ocorrência de oscilação do humor (sintomas depressivos e/ou ansiosos), bem como os possíveis fatores associados à mesma. Neste estudo prospectivo longitudinal 50 pacientes (30 mulheres e 20 homens, com média de idade de 40,6 anos e variação de 18 a 65 anos) com diagnóstico estabelecido de DC foram avaliados durante o período de agosto de 2009 a dezembro de 2010. As principais características sócio demográficas e clínicas relacionados à DC foram registradas. Adotou-se a classificação de Viena para determinação do fenótipo da DC e, para a atividade clinica, o índice de atividade da DC. Os sintomas depressivos e ansiosos foram avaliados por instrumentos de auto avaliação do estado psicológico, o Inventário de Depressão de Beck (IBD) e a Sub-escala de Ansiedade da Escala Hospitalar de Ansiedade e Depressão (HADS-A). Os instrumentos foram aplicados na inclusão no estudo e, a seguir, em intervalos de quatro meses, durante 12 meses subsequentes. A maioria dos pacientes apresentava o fenótipo inflamatório da doença (86%), 18(36%) já haviam se submetido a algum procedimento cirúrgico para tratamento de complicações da DC, sendo que 41(82%) pacientes estavam em remissão clínica na inclusão. Quatorze (28%) pacientes apresentaram humor depressivo de base e 28 (56%) sintomas de ansiedade. Oscilação do humor ocorreu em 29 pacientes (58%); destes 14 (28%) evoluíram com sintomas depressivos e/ou ansiosos a partir do humor normal de base, enquanto 15 (30%) apresentaram normalização do humor depressivo e/ ou ansioso de base. Dos 29 (58%) pacientes com oscilação do humor, 19 (38%) não apresentaram mudança na atividade clínica da doença (p=0,015), enquanto 10 (20%) tiveram alteração na atividade da DC, sendo que 5 (10%) apresentaram reativação da doença previamente em remissão e 5 (10%) remissão da doença que inicialmente encontrava-se em atividade. Os pacientes do sexo feminino e aqueles que não se apresentavam história de cirurgia prévia devido a complicações da DC exibiram significantemente maior oscilação do humor (p=0,04 para ambos). Observou-se uma tendência dos participantes que consumiam álcool a apresentarem maior oscilação do humor (p=0,06), embora o número de pacientes com ingestão alcoólica (n=3) foi pequeno para a análise estatística robusta. Neste estudo verificou-se elevada incidência (58%) de oscilação do humor em pacientes com DC. Não houve correlação entre a oscilação do humor com a mudança de atividade clínica da doença (p=0,15). Conclui-se que os pacientes do sexo feminino e aqueles que não se submeteram a cirurgia prévia devido a complicações da DC apresentaram significantemente maior oscilação do humor. Avaliação psicológica periódica pode ser útil para detecção e possível abordagem da oscilação do humor em pacientes com DC. / Introduction: Crohn Disease (CD) is a chronic inflammatory bowel disease not curable until now. Although psychological issues have been initially considered participants in the etiology of CD this hypothesis was is currently discharged. There are rising evidence that depressive symptoms and anxiety are very frequently in these patients, but little data about humor oscillation and it influence in clinical course of the disease is available. Objective: Estimate the incidence of mood disorders in patients with CD and the possible issues associated with them. Methodology: This prospective longitudinal study evaluate 50 patients (60% female gender; mean age 40.6 yrs) with CD assisted by our institution in a 16 months period time. The clinic activity of the disease was measured by the Crohn’s Activity Index and the mood disorders by Beck Depression Inventory and Hospital Anxiety Scale. The instruments used to assess psychological status were applied in the inclusion and then each four months. Results: The major phenotype of CD found was the inflammatory (86%), 36% had a past history of surgery due to CD complications, 82% had no active disease in the admission period. Humor oscillation (HO) was observed in 58% of patients; 28% had depressive and or anxiety symptoms and 30% had normalization of their baseline depressive or anxiety humor. In 38% of the patients with HO there was no change in disease activity 9p:0.015), while 20% had some degree of variation in clinical activity. Female gender and the absence of previous surgery related to CD were associated with HO (p:0.04). Conclusion: Female gender and the absence of previous surgery due to CD’s complications were associated with HO. Periodically Female gender and previous surgery related to CD’s complication are associated with HO. Periodically psychological evaluation can be worthy for detection and management of HO patients with CD.

Background. General population data were used to study co-morbidities between lifetime social phobia and mood disorders. Methods. Data come from the US National Comorbidity Survey (NCS). Results. Strong associations exist between lifetime social phobia and major depressive disorder (odds ratio 2·9), dysthymia (2·7) and bipolar disorder (5·9). Odds ratios increase in magnitude with number of social fears. Reported age of onset is earlier for social phobia than mood disorders in the vast majority of co-morbid cases. Temporally-primary social phobia predicts subsequent onset of mood disorders, with population attributable risk proportions of 10–15%. Social phobia is also associated with severity and persistence of co-morbid mood disorders. Conclusions. Social phobia is a commonly occurring, chronic and seriously impairing disorder that is seldom treated unless it occurs in conjunction with another co-morbid condition. The adverse consequences of social phobia include increased risk of onset, severity and course of subsequent mood disorders. Early outreach and treatment of primary social phobia might not only reduce the prevalence of this disorder itself, but also the subsequent onset of mood disorders.

Education during recovery could impact a forensic psychiatric patient's community reintegration; however, individual education goals for patients can be difficult due to the lack of available parameters. The purpose of this study was to test whether age at first hospitalization is predictive of educational attainment among forensic psychiatric patients and to determine which ages of first hospitalization best predict 8 levels of educational attainment. Cattell's intelligence theory served as the theoretical framework for this study because mental illness requiring early hospitalization may affect education and learning. This quantitative, nonexperimental study involved a predictive design with data from the Canadian Institute for Health Information database. The sample of patients from 2011-2016 consisted of 16,639 diagnosed with schizophrenia or other psychotic disorder and 2,227 diagnosed with mood disorder. Multinomial logistic regression analysis indicated age at first hospitalization to be a predictor of educational attainment among both categories of diagnoses. Odds ratio analyses identified which ages of first hospitalization best predict 8 levels of educational attainment. Increased rates of education levels were indicated when age at first hospitalization increased. Patients were more likely to attain a high school diploma than drop out between 9th to 11th grade unless first hospitalized at age 14 or under. Based on the results from this study, completion of a general equivalency diploma or a life skills program may provide additional opportunities for independent living and employment, which can improve the lives of patients and those in the community. Therefore, this project can lead to social change by encouraging changes through the results and recommendations presented in a white paper.

復職支援プログラムにおけるマインドフルネス・トレーニングの有効性を評価するための効果指標について検討した。まず、マインレスネス尺度の因子的および構成概念妥当性の検討を行い、「自己不承認」、「表現の抑制」、「不注意」の3因子構造であることを確認した。次に、マインドレスネス尺度は既存のマインドフルネス尺度よりも気分障害患者を対象に行うマインドフルネス・トレーニングの効果をより適切に反映するかを検討した。その結果、本調査のみではマインドレスネス尺度は既存の尺度よりも妥当性が高いと結論づけるに至らなかったため、さらなる検討が求められる。 / The purpose of this paper is to test the reliability and validity of the Mindlessness Scale. The first survey was conducted to examine the factorial and construct validity of the Mindlessness scale. Results suggested that the Mindlessness Scale consists of the three-factor structure: self-judgment, suppression of describing, and non-awareness. The second survey was conducted to test whether the Mindlessness scale obtain more sensitive measurements of therapeutic effects for patients having mood disorders by mindfulness trainings than the Mindfulness scales. Results suggested that the validity could not be determined for the Mindlessness Scale more than the Mindfulness scales, and that additional research is needed. / 博士(政策科学) / Doctor of Philosophy in Policy and Management / 同志社大学 / Doshisha University

Au niveau mondial, la mort par suicide occupe fréquemment la deuxième ou troisième place des causes de décès chez les adolescents (AIPS, 2009). Afin de prévenir le suicide chez les jeunes, une meilleure compréhension des facteurs associés s’avère donc nécessaire. La présente étude avait pour but d’identifier les facteurs de protection d’adolescents atteints d’un trouble de l’humeur et présentant un risque suicidaire. Pour ce faire, un questionnaire relatant les habitudes de vie et facteurs psychosociaux a été analysé. Le risque suicidaire a été évalué à partir de la version adaptée pour adolescents du SAD PERSONS Scale (Juhnke, 1994). L’échantillon de l’étude comprenait 101 jeunes de 12 à 17 ans atteints d’un trouble de l’humeur et présentant un risque suicidaire. Des analyses descriptives, des tests de t, des analyses de variance, des corrélations et des régressions ont été utilisées afin de vérifier la relation entre le risque suicidaire et les facteurs de protection. Il ressort que, pour les adolescents de l’étude, être satisfait du soutien reçu, avoir un bon soutien affectif parental, avoir plusieurs sources de lecture par semaine, souper plusieurs fois avec sa famille par semaine, ne pas fumer de cigarette, ne pas avoir beaucoup d’amis qui fument la cigarette, ne pas consommer d’alcool, ne pas consommer de drogue ainsi que de ne pas mélanger la consommation d’alcool et de drogue peuvent tous agir, individuellement, comme facteurs de protection du suicide chez des adolescents atteints d’un trouble de l’humeur et présentant un risque suicidaire. Par ailleurs, les analyses effectuées ne révèlent aucune relation significative entre les habitudes scolaires, l’activité physique, les habitudes de sommeil, l’estime de soi et le risque suicidaire des adolescents de l’étude. Enfin, miser sur les facteurs de protection du suicide identifiés par la présente étude constitue une nouvelle piste intéressante pour les infirmières et des recommandations pour la recherche et la pratique infirmière sont suggérées. / Adolescent suicide often represents the second or third leading cause of death for this age group throughout the world (AIPS, 2009). In order to prevent adolescent suicide, a better understanding of the factors associated with suicidal risk is necessary. The aim of this study was to identify the protective factors of adolescents with mood disorders and suicidal risk. Life habits and psychosocial factors were evaluated by an auto-administrated questionnaire. The adapted version of the SAD PERSONS Scale (Patterson, Dohn, Bird & al, 1983) for children and adolescents (Juhnke, 1994) was used to evaluate the suicidal risk. The sample of this study included 101 teenagers, aged between 12 and 17 years old, who had a mood disorder and a suicidal risk. Descriptive analysis, T-tests, variance analysis (ANOVA), correlation analysis and multiple regressions were conducted to examine the relationship between the suicidal risk (dependant variable) and the life habits and psychosocial factors (independent variables). The results indicate that, for 12 to 17 year olds, being satisfied with the support received, having good parental support, having many different sources of reading, eating supper with their family frequently, not smoking cigarettes, not having many friends who smoke cigarettes, not drinking, not doing drugs and not drinking and doing drugs simultaneously can all act as individual protective factors for suicidal risk. On the other hand, the results of this study do not show any statistically significant relations between school habits, physical activity, sleep habits, self-esteem and suicidal risk for teenagers with mood disorders. Finally, examining protective factors seems to be useful in helping teens with mood disorders and suicidal risk. The results of this study encourage nurses to include protective factors in their evaluation of suicidal adolescents and interventions. Research and clinical recommendations are therefore suggested.

O Câncer Colorretal (CCR) consiste no terceiro tipo de câncer mais comum em homens e o segundo em mulheres. O tratamento, na maioria dos casos, implica na cirurgia geradora de estoma, que constitui um procedimento invasivo, com grande impacto em todas as áreas na vida da pessoa. O presente estudo teve por objetivos investigar prospectivamente variáveis relacionadas à imagem corporal, sintomas ansiosos e depressivos, domínios da Qualidade de Vida Relacionada a Saúde (QVRS) e as cognições, emoções e comportamentos diante do processo de adaptação ao estoma. Trata-se de um estudo exploratório, longitudinal e de abordagem quanti qualitativa. A amostra foi composta por pacientes adultos (n=122), de ambos os sexos, atendidos no Ambulatório de Estomaterapia do Hospital de Câncer de Barretos (SP). A avaliação quantitativa foi realizada em todos os pacientes e a qualitativa em 26 dos pacientes, sorteados aleatoriamente. Os participantes foram avaliados em quatro momentos (pré-operatório, três, seis e quinze meses após a cirurgia) e foram subdivididos de acordo com o tipo de procedimento cirúrgico realizado (Anastomose Primária, Estomia Intestinal Temporária e Estomia Intestinal Definitiva). Para a coleta de dados, foram utilizados os instrumentos: questionário de dados sociodemográficos; Critério de Classificação Econômica Brasil; ficha de condições clínicas; Escala de Figura de Silhuetas (EFS); Escala de Ansiedade e Depressão para Hospital Geral (HADS); Questionários para avaliação da QVRS (EORTC QLQ-C30/ QLQ-CR38); Medida subjetiva de pensamentos e emoções e Roteiro de entrevista semiestruturada. Os resultados demonstraram que a amostra foi constituída por pacientes mais velhos, de baixa renda e escolaridade. Os valores médios encontrados na avaliação da imagem corporal indicaram uma superestimação desta. Apesar dos participantes não terem apresentado sintomatologias graves para ansiedade e depressão, de acordo com a escala HADS, as comparações estatísticas infere-se que, quanto pior a sintomatologia para ansiedade e depressão, pior a saúde global. Segundo o EORTC QLQ-C30 e QLQ-CR38 a maioria dos domínios de QVRS apresentaram níveis moderados, sendo que os piores sintomas foram os sexuais. A depressão influenciou de forma direta e negativa na saúde global, assim como na acurácia da imagem corporal. Foram encontradas diferenças significantes entre os grupos na comparação das variáveis nos diversos momentos de avaliação, sugerindo que o nível dos sintomas variou de acordo com o tempo. Não foram encontradas altas frequências para as distorções cognitivas nesses pacientes, entretanto, observou-se pela entrevista semiestruturada que na primeira avaliação existia grande preocupação quanto às limitações ocasionadas pela estomia intestinal em detrimento da percepção de normalidade, frequentemente reportada na última avaliação. Conclui-se que a entrevista qualitativa complementou os resultados encontrados na abordagem quantitativa, sendo que a análise de conteúdo reforçou que os pacientes, em geral, apresentaram boa adaptação à estomia. O suporte social foi apontado como uma das principais estratégias utilizadas no processo de adaptação. Neste sentido, orientações psicoeducativas aos pacientes e familiares devem ser realizadas desde o diagnóstico, a fim de contribuir para adaptação ao estoma. / The Colorectal Cancer (CRC) is the third most common type in men and the second in women. The treatment in most cases implies a surgery with a stoma, which is an invasive procedure, with a great impact in all areas in a person\'s life. This study aimed to prospectively investigate variables related to body image, depression and anxiety symptoms, areas of Health Related Quality of Life (HRQoL) and cognitions, emotions and behaviors related to the adaptation process to the stoma. It is an exploratory study, longitudinal, with quantitative and qualitative approach. The sample consisted of adult patients (n = 122), of both sexes, attended in Stomatherapy Clinic of Barretos Cancer Hospital. The quantitative evaluation was performed in all patients and the qualitative evaluation was performed in 26 patients randomly selected. Participants were assessed at four time points (preoperative, three, six and fifteen months after surgery) and were subdivided according to the type of surgical procedure performed (Primary Anastomosis, Temporary Intestinal Ostomy and Definitive Intestinal Ostomy). For data collection, the follow instruments were used: socio-demographic questionnaire; Brazilian Economic Classification Criteria; clinical conditions record; Figures of Silhouettes Scale (FSS); Hospital Anxiety and Depression Scale (HADS); Questionnaires to assess the HRQoL (EORTC QoL-C30 / QoL-CR38); Subjective measure of thoughts and emotions and Semi-structured interviews. The results showed that the sample was composed of older patients, with low income and low education level. The mean values found in the evaluation of body image showed an overestimation of it. Although the participants did not show servere symptomatology for anxiety and depression, according to the HADS, statistical comparisons inferred that, the worse the symptoms for anxiety and depression, worse overall health. According to the EORTC QoL-C30 and QoL-CR38 most HRQoL domains showed moderate levels in which the worst symptoms were sexual. Depression had a direct and negative impact on global health, as well as the accuracy of body image. Significant differences were found between groups when comparing the variables in the different time points, suggesting that the level of symptoms varied according to the time. There were no high frequencies for cognitive distortions in these patients; however, the semi-structured interview shows that in the first assessment there was great concern about the limitations caused by intestinal ostomy at the expense of perceived \"normal\" often reported in the last assessment. We conclude that the qualitative interview complemented the findings in quantitative approach, and the content analysis emphasized that patients generally showed good adaptation to the stoma. Social support was considered one of the main strategies used in the adjustment process. In this sense, psychoeducational guidance to patients and their families must be carried out from diagnosis, in order to contribute to the adaptation to the stoma.

Some women have a particular sensitivity to hormonal changes, starting in early menarche, which increases their vulnerability to psychological stressing agents that are triggered by environment and physiological factors during life. Decreased serum brain-derived neurotrophic factor (BDNF) levels have been associated to different neuropsychiatric conditions and BDN has been considered as a candidate marker for such disfunctions. The goal of this study was to compare the levels of BDNF between mothers with PPD and control mothers as well as to seek for associations between BDNF levels and the severity of PPD. METHODS: This is a case-control study including 36 mothers with PPD and 36 control mothers. PPD was defined according to the Beck Depression Inventory (BDI). Serum BDNF was assayed with the sandwich ELISA method. RESULTS: Serum levels of BDNF were significantly lower in women with PPD than in control mothers (p = 0.026). No significant correlation between BDI score and serum BDNF levels was observed (r= 0.16, p = 0.09). CONCLUSIONS: Our study suggests that low BDNF levels are associated with PPD, although not with PPD severity. This result point out to the potential usage of BDNF in the screening of PPD, which could promote early treatment and, therefore, reduce the burden to the PPD women and to the health system / O BDNF (brain-derived neurotrophic factor) é um fator neurotrófico que parece estar envolvido na fisiopatologia de muitos transtornos psiquiátricos, incluindo depressão 1. O pós-parto é um período de risco psiquiátrico aumentado no ciclo de vida da mulher. A depressão pós-parto pode se manifestar com intensidade variável, tornando-se um fator que dificulta o estabelecimento de um vínculo afetivo seguro entre mãe e filho, podendo interferir nas futuras relações interpessoais estabelecidas pela criança. Fatores neurotróficos, ou neurotrofinas são famílias de proteínas, nas quais são capazes de promover o desenvolvimento, modulação e sobrevivência dos neurônios no sistema nervoso central (SNC) e periférico. Estes fatores são secretados pelos tecidos e vão atuar de diversas maneiras tais como na modulação sináptica, na apoptose, na diferenciação celular, dentre outras. O BDNF é crítico no desenvolvimento e modulação do SNC 2. As diversas funções das neurotrofinas são mediadas via duas classes de receptores: o Trk (cinase do receptor tropomiosina), da família dos RTKs (receptor da tirosina cinase), e o p75NTR (receptor da neurotrofina p75). Os subtipos dos receptores Trk ligam-se a neurotrofinas maduras com diferentes especificidades. O TrkB preferencialmente liga-se ao BDNF e ao NT4 (neurotrofina-4). O p75NTR liga-se a todas neurotrofinas maduras com baixa afinidade. O p75NTR também pode interagir com outros receptores, incluindo os receptores Trks 3. Para a mulher, o ciclo gravídico-puerperal é considerado período de risco para o psiquismo devido à intensidade da experiência vivida 4. A prevalência deste transtorno pode variar de acordo com os critérios utilizados para o diagnóstico, como o período de início dos sintomas e o método utilizado para a avaliação. Uma meta-análise estimou uma prevalência de 10 13% de depressão pós-parto (DPP) em mulheres 5. Recentemente, Moraes et al. (2006) e Pinheiro et al. (2006) encontraram prevalência de DPP de 19,1% em mulheres na cidade de Pelotas/RS 6,7. A partir da primeira semana após o parto 80% das mulheres apresentam um estado de tristeza materna (baby blues), podendo vir a ser confundido com a depressão. O quadro é benigno e regride por si só por volta do primeiro mês. Os sintomas mais freqüentes são: irritabilidade, mudanças bruscas de humor, indisposição, tristeza, insegurança, baixa auto-estima, sensação de incapacidade de cuidar do bebê, entre outros 8. Recentemente, o envolvimento do BDNF, tem sido foco de interesse na pesquisa relacionada com a regulação dos transtornos de humor e depressão. Interessantemente, diversos estudos caso-controle têm encontrado níveis séricos de BDNF diminuídos em pacientes deprimidos. Nos casos em que a depressão é induzida por alterações nos níveis de BDNF, os sintomas desaparecem após o final do tratamento ou com o uso de antidepressivos 1,9,10. A descoberta de novos marcadores pode não só auxiliar no diagnóstico, monitoramento, como também na escolha do tratamento a ser seguido, bem como no desenvolvimento de novos fármacos para o tratamento da depressão. Existem fortes evidências do envolvimento do BDNF na fisiopatologia da depressão, como esses achados envolveram exclusivamente amostras clínicas oriundas de sistema terciário, o fato de utilizarmos uma amostra comunitária aumenta a representatividade dos achados, e é relevante ao entendimento da neurobiologia e conseqüentemente abre caminho à pesquisa de novas abordagens no tratamento da DPP. Sendo assim o presente estudo pretende utilizar medidas mais sofisticadas para o diagnóstico e intervenção no tratamento da DPP, relacionando essa patologia com a concentração sérica de BDNF

L’adhésion au traitement réfère à la mesure selon laquelle un patient respecte la posologie et la fréquence des prises médicamenteuses telles que prescrites par le médecin pour la durée recommandée. En dépit de nombreux traitements efficaces, la problématique de la non-adhésion demeure omniprésente en médecine, notamment dans les populations psychiatriques. Les patients aux prises avec un trouble de l’humeur ou un TDAH peuvent présenter des déficits cognitifs. Un projet de recherche mené auprès de 52 patients est présenté. Les résultats montrent une association entre les difficultés cognitives telles que perçues par les patients et l’adhésion. Des sous-domaines cognitifs comme la capacité d’inhibition, la flexibilité, la mémoire de travail, la planification et l’organisation de même que la capacité d’initier une action sont particulièrement impliqués. La capacité d’initier une tâche est corrélée avec l’adhésion et tend à la prédire. L’utilisation en clinique de méthodes d’évaluation simples et rapides de la cognition et de l’adhésion permettrait d’identifier ces difficultés. Des interventions visant à améliorer l’adhésion pourraient ainsi être offertes de façon plus ciblée. L’adaptation des interventions au profil de chaque individu est une avenue à explorer davantage pour tenter d’améliorer l’efficacité limitée de celles-ci jusqu’à maintenant. / Adherence refers to the extent to which a patient respects the dosage and frequency of medication taken as prescribed for the recommended time. Despite the availability of many effective treatments, the problem of non-adherence is ubiquitous in medicine and in the psychiatric population. Patients with mood disorder or ADHD often have cognitive deficits. A research project conducted with 52 patients is presented. Results show that cognitive difficulties as perceived by patients reduce adherence. Areas such as inhibition, shift, working memory, planning and organization and the ability to initiate an action are particularly important. Ability to initiate tasks shows a trend to predict poorer adherence and correlates with adherence. Quick and simple tools permitting the assessment of cognition and adherence in clinical practice could help identify these problems. Targeted adherence enhancing interventions could then be offered to patients with such difficulties. Choosing interventions adapted to the individual on the basis of the specific profile of adherence influencing factors is an avenue which requires further exploration.
