Malgré les avancées considérables pour la prévention et le traitement des troubles du comportement alimentaire (TCA) au courant des dernières années, l’accès à des services de qualité demeure limité pour trois principales raisons : 1) certaines caractéristiques de la population qui présente un TCA peuvent être associées à de la stigmatisation et faire en sorte que des personnes dans le besoin ne reçoivent pas de traitement, 2) la présence d’un écart entre les pratiques fondées sur des données probantes disponibles et les pratiques des intervenants et 3) le format utilisé pour disséminer les pratiques fondées sur des données probantes recommandées (i.e. formation de cliniciens aux études supérieures) limite le nombre d’intervenants formés pour intervenir. Devant ces constats, l’étude du transfert des connaissances (TC) représente un incontournable pour faciliter l’utilisation de pratiques fondées sur des données probantes par les intervenants. La présente thèse vise à mieux comprendre l’écart présent entre la recherche et la pratique dans le domaine des TCA afin de soutenir l’accès à des traitements démontrés efficaces pour la population. Les principaux objectifs de cette thèse consistent à dresser un portrait des effets de stratégies de TC disponibles (ex: matériels éducatifs, guides de pratique, formations, supervisions), de documenter les déterminants influençant l’utilisation de pratiques fondées sur des données probantes par les intervenants et d’identifier des applications potentielles en contexte québécois. La thèse comporte deux articles scientifiques et une discussion critique des résultats issus de ces articles. Le premier article présente une recension systématique des écrits concernant les effets de stratégies de TC existantes et les déterminants influençant l’utilisation par des intervenants et équipes de traitement pour les TCA. Les résultats suggèrent qu’une combinaison de stratégies de TC peut être employée selon les contextes d’intervention pour faciliter l’accès à des services. Peu d’études répertoriées ont identifié des conditions favorables à la prise de décision et au travail interdisciplinaire pour les TCA. L’article propose des pistes de réflexion et d’action pour favoriser l’utilisation par les intervenants tout en tenant compte des défis associés à l’intervention en TCA. Le second article évalue les retombées d’une formation visant l’utilisation de pratiques de dépistage et de référence par des intervenants québécois. Les résultats démontrent une utilisation instrumentale, conceptuelle et persuasive des connaissances par les intervenants et identifie des conditions susceptibles d’influencer cette utilisation. Cette thèse contribue à l’avancement des connaissances en proposant différentes pistes pour faciliter l’utilisation de pratiques fondées sur des données probantes par les cliniciens tout au long du processus de prise de décision clinique. / Despite considerable recent advances in the field of eating disorders (ED) prevention and intervention, access to quality care is limited because: 1) stigma associated with certain ED characteristics can lead to EDs’ going undiagnosed and untreated; 2) healthcare professionals do not always apply available evidence-based practices; and 3) given that knowledge on evidence-based practices is currently disseminated primarily in graduate programs, there are not enough clinicians trained in ED intervention. Thus, the study of knowledge transfer (KT) is vital to facilitate uptake of evidence-based practices by healthcare professionals. The aim of the present thesis is to better understand the research–practice gap in the field of ED with a view to improving access to evidence-based treatment. More specifically, the aim of this thesis is to document outcomes of KT strategies (e.g. educational materials, clinical guidelines, training workshops, supervision) and conditions influencing healthcare professionals’ evidence-based practices. Potential applications for Quebec’s intervention context are also of interest. The thesis consists of two articles and a discussion of main results. The first article documents, in a systematic review, the effects of available KT strategies and conditions influencing evidence-based practices of healthcare professionals and ED treatment teams. The findings suggest a combination of KT strategies might facilitate access to care. Articles reporting conditions that might support decision-making or interdisciplinary work were rare. In light of known challenges in ED intervention and the findings of this review, recommendations are presented to improve evidence uptake. The second article evaluates the impact of a training workshop on ED screening and referral practices by healthcare providers in Quebec’s first-line services. Results indicate that healthcare professionals used evidence- based knowledge in diverse ways (instrumental, conceptual and persuasive use) and under different conditions. This thesis furthers knowledge by identifying relevant strategies for facilitating healthcare professionals’ uptake of evidence-based practices throughout their decision-making processes.

Whether it is offering services, delivering solutions or driving innovations, team work has been a hallmark of efficiency and effectiveness in various industries. The healthcare industry is not left out as its service delivery process involves numerous interfaces, information flows and patient hand-offs among professionals with different educational training, differing knowledge levels and possibly working from different locations as well. As healthcare delivery evolves to being more patient-centered, so does the team settings as well, becoming more collaborative. Such changes also translate into a need for support systems to evolve to be able to provide support for the extent of collaboration that would be needed. A framework is needed to guide in the development of such systems. However, due to the varying needs of patients, team types and make-up would generally differ, so we explored the different types of team settings studying what they entail based on their various degrees of collaboration. We therefore present in this thesis a model of team based concepts, an ontology formalizing the model, team based scenarios designed using the ontology and then application of the scenarios to test the ability of BPMN (Business Process Modeling Notation) to model healthcare teams.
