Depuis une vingtaine d’années, le modèle cognitif basé sur les interprétations (Groupe de recherche sur la cognition dans le trouble obsessionnel compulsif [OCCWG], 1997, 2001, 2003, 2005) représente le modèle psychologique de l’étiologie et du maintien du TOC le plus étudié au plan empirique. Cependant, peu de recherches ont porté sur les deux postulats importants du modèle touchant respectivement le développement des croyances liées à l’obsessionnalité et la contribution des états affectifs au maintien des interprétations et des croyances (réactivité cognitive). L’objectif de cette thèse est de contribuer à la validation empirique de ces postulats. Fondé sur un devis corrélationnel dans un échantillon de participants mixte (participants troubles obsessionnels-compulsifs et participants non cliniques), le premier article étudie les liens entre les expériences de l’enfance et la présence de croyances obsessionnelles chez l’adulte. Deux modèles alternatifs sont comparés qui représentent d’une part un lien spécifique, et d’autre part un lien non spécifique entre les expériences de l’enfance et les croyances obsessionnelles adultes. Les résultats suggèrent la présence à la fois de relations spécifiques et non spécifiques entre les expériences de l’enfance et les croyances adultes. Les expériences de l’enfance et les domaines de croyance obsessionnels qui montrent des liens spécifiques sont ceux relatifs à la responsabilité, à la perception du danger, et au perfectionnisme. En contrepartie, les expériences de l’enfance relatives à la perception de danger et dans une moindre mesure la sociotropie, apparaissent étroitement liés à la plupart des domaines de croyances adultes (intolérance à l’incertitude, surestimation du danger, importance et contrôle des pensées). Dans la seconde étude, nous nous intéressons à la mesure et l’analyse longitudinales de la réactivité cognitive telle qu’elle s’exprime dans l’environnement naturel de huit participants troubles obsessionnels-compulsifs de type ruminateur. Par le biais de huit protocoles à cas uniques intensifs, l’analyse de contingence entre les scores quotidiens d’humeur (4 états émotionnels cotés par participant) et d’interprétations (une interprétation idiographique des intrusions par participant) permet d’établir une mesure de l’importance de la réactivité cognitive chez chaque participant. Ces résultats sont ensuite analysés du point de vue des postulats principaux de deux modèles spécifiques de la réactivité cognitive (modèle de l’Infusion de l’affect [Forgas, 2008] et modèle de l’Humeur comme intrant [Meeten & Davey, 2011]. Ainsi, les analyses intra-individuelles répétées trans-comportements) et interindividuelles (trans-participants) permettent d’illustrer le rôle proximal déterminant des stratégies de traitement de l’information (traitement systématique; traitement superficiel; traitement altéré) employées par les participants. En résumé, les résultats obtenus dans ces deux études fournissent des données utiles à la poursuite de la validation du modèle des interprétations du TOC. Dans la première étude, l’identification de liens spécifiques entre les EE et les croyances obsessionnelles soutient la séquence étiologique postulée, alors que l’identification de liens non spécifiques suggère que d’autres trajectoires étiologiques peuvent être pertinentes. Dans la seconde étude, l’analyse longitudinale et naturaliste des covariations humeur – interprétations se révèle d’abord féconde à identifier les phénomènes de réactivité cognitive postulés dans le modèle des interprétations. Ensuite, en conformité aux modèles intégrés de la réactivité cognitive, l’analyse des liens entre cette réactivité et les stratégies privilégiées de neutralisation des participants permet d’identifier le rôle clé des différentes stratégies de traitement de l’information dans la réactivité cognitive. / Over the past twenty years, the «appraisal model» of obsessive-compulsive disorder (OCD) (Obsessive Compulsive Cognition Working Group, 1997, 2001, 2003, and 2005) has drawn most of the empirical research on the psychological etiology and maintenance of the disorder. Nevertheless, only a few studies addressed two important postulates of the model, which is the development of beliefs associated with OCD, and the contribution of affective states to the maintenance of appraisals and beliefs (p. ex., cognitive reactivity). The current thesis aims to contribute to the empirical validation of these postulates. Based on a retrospective correlational design in a mixed (OCD and normal) sample, the first article aims to explore the links between childhood experiences (CEs) and adult OCD related beliefs. Two alternative etiological models are compared emphasizing either a rather specific association between different CEs and beliefs; or conversely, a broad non-specific association between CEs and different OCD related beliefs. Results support both the existence of specific and non-specific associations between CEs and beliefs. CEs and OCD related beliefs that showed specific links were those CEs that showed specific links to OCD related beliefs were those related to the concepts of Responsibility (R-E and OBQ-R), Threat perception (TP-E et OBQ-T), and Perfectionism (SO-E et OBQ-P). On the other hand, CEs emphasizing Threat perception (TP-E) and Sociotropy (SOC-E) related experiences also showed significant links with most OCD related beliefs (Intolerance of uncertainty [OBQ-U], Overestimation of threat [OBQ-T], Importance and Control of thoughts [OBQ-I et OBQ-C]). The aim of the second article is to assess and analyze cognitive reactivity in an OCD sample (rumination subtype) through a longitudinal naturalistic design (eight intensive single-case designs). In a first step, the contingency analysis between daily mood-states scores (4 mood-states in each participant) and daily thought appraisals (one idiosyncratically defined thought appraisal in each participant) allows for the assessment of the magnitude and rate of cognitive reactivity in each participant. On the basis of integrative models of cognitive reactivity (Affect Infusion Model, and Mood as input Hypothesis) further repeated intra-individual analyses (across subjects) and inter-individual analyses (between subjects) illustrate the critical proximal role of different processing strategies used by the participants. In summary, both studies provide results that contribute to further the validation of the appraisal model of OCD. In the first study, the identification of specific links between CEs and OCD related beliefs in adults supports the postulated etiological sequence; while the identification of non-specific links suggest that other etiological paths may be relevant In the second study, the longitudinal investigation of covariations between mood-states and appraisals of thoughts allows to reveal the expected cognitive reactivity processes. Such processes are further supported with reference to integrated models of cognitive reactivity that emphasize the critical role of different processing strategies in their expression.

Substance Use Disorder (SUD) has plagued families of rural Appalachia for many years, perpetuating involvement in the criminal justice system as well as generational trauma for people diagnosed with SUD and their children. This points to the necessity of a trauma-informed, restorative-justice based framework for rehabilitative services to most effectively heal families, address trauma, and re-integrate people diagnosed with SUD into society. A restorative justice-based program would provide health care services for addiction and any comorbid mental health disorders as well as teach parents how to properly provide for themselves and their families, manage finances, obtain employment, and further education. Current rehabilitative program structures were evaluated in the literature, and it was found that typically, rehabilitative programs provide either strictly addiction services or mental health services, but not both. It was also found that the criminal justice system tends to sentence to 28-day inpatient rehabilitative services, which provides people diagnosed with SUD an opportunity to achieve sobriety and establish some stability; however, with little or no follow up, these people are significantly more likely to relapse. These findings were compared with the structure of Ballad Health STRONG Futures, an outpatient addiction services and behavioral health clinic located in Greeneville, TN; Red Legacy Recovery, a recovery initiative serving incarcerated women in Elizabethton, TN; and Families Free, a 501(c)3 organization providing outpatient services to Northeast Tennessee through the Tennessee Department of Mental Health and Substance Abuse Services. It was found that rehabilitative care structures that addresses trauma, addiction, and aspects of daily living such as parenting, finances, education, and employment provides clients with the tools and stability needed to be successful in their respective recovery journeys. This work will provide significant insight for the creation and implementation of other substance use clinics and initiatives across the country and encourage them to address mental health and aspects of daily living to promote clients' success and break cycles of generational trauma.

Alternative school settings are success prospects for students at risk of school failure. However, research on the daily experiences of the special educators in alternate school settings tasked with educating the at-risk population, is limited. The purpose of this phenomenological study was (a) to recognize the perceptions of special educators concerning their preparation to advance the success of SEN students who are at risk of school failure; (b) to determine how to improve special educator preparation programs in alternative school settings. Deci and Ryan's self-determination theory, focused on student success provided the study's framework. Twelve semistructured interviews were conducted to examine special educators' perceptions on preparation and practice for student success. Data were analyzed through block coding, code comparison and thematic searches. The study's results included accounts of special educators' perceptions and challenges related to preparation and practice for student success in alternate school settings. Emergent themes included applying classroom structure and technology, as well as individualized student instruction. Participants cited a need for rich teacher/student relationships to advance student success. Included are inferences regarding the development of teacher/student relationships. Also included are suggestions for educational leaders to consider while preparing preparatory methods for special educators who teach within the alternative school setting such as administrator knowledge of what special educators require to teach in the alternate classroom. This study may lead to social change by providing information on special educator preparation coursework meant to develop student success for the alternative school student population.

Fans of college sports embrace the idea of athletes playing sport and, in turn, receiving tuition scholarships that provide them an opportunity to trade athletic talent for a free education. A contradictory body of research using internal colonization theory posits that the trade of education for playing sports is not a fair exchange but is fraught with exploitation that continues to perpetuate subjugation. An accepted narrative in athletic competition is that the recruiting pipeline draws athletes from impoverished inner-city areas engaging young athletes who experience difficulties keeping up scholastically becoming academically resistant as they focus on their sport at the expense of their academics. Biopsychosocial and developmental neuroscience research recognizes outside social factors as variables that affect the development of the brain, thus influencing basic mechanical operations of specific brain structures. This dissertation breaks new ground by utilization of the 10-question Adverse Childhood Experiences (ACE) Inventory to explore a possible relationship between ACE scores and Academic Resistance (AR), ACE scores and Locus of Control, and ACE scores and Identity Foreclosure. Using the T-test to determine a relationship between 194 participants’ ACE scores and AR, the findings showed the probability of Type I error of 5%, to be that the AR of student athletes with an ACE score >=2, n=94, to be significantly higher than the AR of student athletes with an ACE

[pt] Estudos sobre as primeiras interações das crianças com seu ambiente apontam para possíveis efeitos do estresse tóxico na infância, como facilitador de comportamentos de risco na adolescência, além de prejuízos para o desenvolvimento de habilidades cognitivas e socio emocionais (Van der Kolk, 2003). Pela necessidade de as escolas estarem preparadas para atenderem crianças que experimentam altas e frequentes taxas de estresse no início de suas vidas e precisam lidar com seus efeitos, a escola como um todo precisa ser um espaço de segurança e resiliência para que as crianças possam experimentar um processo de aprendizagem. A partir de uma perspectiva ecológica da Psicologia do desenvolvimento, o objetivo do presente trabalho foi realizar uma revisão narrativa de literatura para identificar práticas e modelos da educação sensível ao trauma, voltados para proteção contra os efeitos do estresse tóxico sobre o desenvolvimento cognitivo na educação infantil e primeiros anos do ensino fundamental. Foram selecionados 50 artigos sobre diferentes modelos de educação sensível ao trauma nos primeiros anos de escolarização e com abordagens voltadas para a escola como um todo. A partir da análise desses artigos, foram identificados nove aspectos principais dentre os diferentes modelos apresentados: autorregulação emocional, treinamento dos(as) profissionais de educação, engajamento comunitário, preparação de ambientes psicologicamente seguros, apoio emocional para os(as) educadores(as), rotinas e rituais na prática pedagógica, vínculo seguro, atendimento individual ou em grupo e contato regular com as famílias. Acredita-se que esses elementos podem orientar intervenções voltadas para primeira infância em contextos de vulnerabilidade, no âmbito da educação. / [en] Studies on children s first interactions with their environment point to possible effects of toxic stress in childhood, as a facilitator of risky behavior in adolescence, in addition to impairments for the development of cognitive and socioemotional skills (Van der Kolk, 2003). Due to the need for schools to be prepared to serve children who experience high and frequent stress rates early in their lives and need to deal with its effects, the school as a whole needs to be a space of safety and resilience so that children can experience a learning process. From an ecological perspective of developmental psychology, the objective of the present study was to carry out an integrative literature review to identify practices and models of trauma informed education, aimed at protecting against the effects of toxic stress on cognitive development in preschool and early years of elementary school. Fifty articles were selected on different models of trauma informed education in the first years of schooling and with approaches aimed at the school as a whole. From the analysis of these articles, nine main aspects were identified among the different models presented: self-regulation, professional training of trauma and toxic stress, community engagement, psychologically safe environments, emotional support for teachers, routines and rituals in pedagogical practice, secure attachment, individual or group therapy and regular contact with families. It is believed that these elements can guide interventions aimed at early childhood, in the context of education.
