Major Depressive Disorder: Precursors, Predictors, and Coping Mechanism Among Undergraduate StudentsBickham, Grace Antia 01 January 2015 (has links)
Major depressive disorder (MDD) is common among college students. The disease perpetuates depressive symptoms and potentially leads to chronic depressive episodes. Existing literature has shown that students who use both cognitive and behavioral maladaptive coping skills are more prone to endure depressive symptoms and poorer academic performance. Despite these known associations, little research has examined the relationship between coping skills and self-efficacy in response to warning signs of MDD in college students. This study sought to fill the gaps in the research of MDD related to precursors, predictors, and coping mechanisms among undergraduate students in a national sample of U.S. college students. Secondary data (N = 6,713) were analyzed from the Healthy Minds Study 2012, which used the Patient Health Questionnaire-9 (PHQ-9) with a test-retest reliability. Social learning and social cognitive theories were used as the theoretical frameworks to focus on problems such as management of life activities, academic success, and maladaptive beliefs. Analyses of the data from the cross-sectional survey using multiple linear and logistic regressions indicated a statistically significant relationship between depressive symptoms and the potential predictive factors of MDD. These findings contribute positively to social change by informing the work of therapists and program developers, who may use these results to create programs that reduce depressive symptoms among undergraduates.

Développement d'une échelle de mesure de la souffrance chez les adolescents ayant le cancerKhadra, Christelle 07 1900 (has links)
La complexité du traitement oncologique a amélioré les taux de survie des adolescents ayant le cancer mais a également augmenté leur souffrance. Le but de la présente étude était d'élaborer une échelle pour mesurer la souffrance chez cette population. À partir d’entrevues semi-structurées auprès de 19 adolescents et 16 experts, un pool d’items associés à la souffrance a été créé. Les items ont été présentés à un panel de neuf experts pour déterminer leur validité de contenu. Les analyses ont montré une validité de contenu élevée de l’échelle par l’indice de validité de contenu de 0,98 associé à un accord inter-juges de 0,88. La majorité des items étaient considérés faciles à comprendre et à y répondre. L’Échelle de Souffrance des Adolescents ayant le cancer (ESAC) est de type likert à quatre choix de réponses. Elle comprend 41 items portant sur la souffrance physique, psychologique, sociale, spirituelle, cognitive et globale. / The complexity of cancer treatment has improved the survival rates among adolescents with cancer but has also increased their suffering. The purpose of this study was to develop a scale to measure suffering in this population. A pool of items associated with suffering was created after analysing the verbatim of semi-structured interviews conducted with 19 patients and 16 experts. The items were then presented to nine experts to determine their content validity. The analysis showed a high content validity of the scale with a content validity index (CVI) of 0.98 associated with an interrater agreement (IRA) of 0.88. The majority of the items were considered easy to understand and answer. The scale, called the “Suffering Scale of Adolescents with Cancer” (SSAC), is a likert type scale with four answer choices. It comprises 41 items about physical, psychological, social, spiritual, cognitive and global suffering.

Explaining and predicting psychological problems : the joint importance of positive and negative constructsSiddaway, Andrew P. January 2017 (has links)
Positive Clinical Psychology (PCP) argues that positive and negative psychological constructs are jointly important for explaining psychological problems. “Positive” constructs have been explicitly focused on by positive psychology researchers and “negative” constructs have been explicitly focused on by mental health researchers. This thesis examines the relationship between positive and negative constructs in relation to four psychological problems: depressive symptoms (Chapter 2), anxiety-problems (Chapter 3), suicide attempts (SAs) (Chapter 4 and 5), and nonsuicidal self-injury (NSSI) (Chapter 4 and 5). Clarifying how psychological problems are most appropriately conceptualised has implications for definitions, diagnostic criteria, measurement, and clinical interventions. This thesis provides evidence that some constructs form bipolar continua, having a positive pole and a negative pole, whilst other constructs do not. Chapters 2 and 3 demonstrate that well-being and calmness respectively form continua with depressive and anxiety symptoms. In contrast, Chapters 4 and 5 demonstrate that SA and NSSI cognitions do not form a continuum with another construct. Results indicate that positive and negative constructs appear to have different relationships to one-another depending on the construct under investigation. Constructs that are common in the general population – such as depressive symptoms, anxiety symptoms, well-being symptoms, and calmness symptoms – appear to be bipolar, having a positive and a negative pole. Psychological constructs that are rare in the general population and which specifically characterise psychological problems (rather than being an extreme manifestation of a common psychological experience) – such as SA and NSSI cognitions – appear to be unipolar. The replication of scientific findings also features strongly throughout this thesis. Each chapter may therefore have a timely bearing on the emerging “replication crisis” literature.

An evaluation of advertising strategies developed according to the FCB grid and the Bendinger formulaYssel, J. C. (Johan Christiaan), 1936- 12 1900 (has links)
This thesis argues that the FCB (Foote, Cone and Belding) grid can not only be
used by advertising students to write strategy, but also to write superior strategies.
To demonstrate this, the research in this study identifies two versions of the FCB
grid that can serve as guidelines for students when writing advertising strategy.
The argument is substantiated by the results of a statistical analysis of strategies
written according to the FCB grid and the Bendinger formula.
A discussion of the areas which were researched and led to the introduction of the
FCB grid, as well as an explanation of the FCB grid, provide the context in which
the grid should be viewed as a guideline for writing advertising strategy.
Thereafter, a summative overview of what advertising strategy and the Bendinger
formula encompass, identifies the complexed nature of advertising strategy, as well
as the minimum areas which need to be addressed when attempting to write
strategy. A detailed discussion of the method which was employed and the
instrument developed to evaluate the effectiveness of strategies, precedes the
experimental results. A critical discussion of the results obtained from the statistical
analysis and the literature on advertising strategy provide a theoretical foundation
on which a model, to be used in conjunction with the FCB grid to write strategy, is
designed. The model is then explained to illustrate how students can, in
conjunction with the FCB grid, apply it to write advertising strategy.
This thesis recommends that, in order to improve on the suggested method of
evaluating strategies, the measurement scale developed in this study could be
considered as a starting point. A further recommendation is that the experiment
comparing strategies written according to the FCB sextant grid to those written
according to the FCB quadrant grid, could provide the need for further research.
The thesis concludes that as far as could be determined, this was the first time that
a study of this nature was undertaken and that the need for future research to
validate this study and its results, exists. / Communication Science / D. Litt et Phil. (Communication)

Attitudes stigmatisantes envers les personnes vivant avec le VIH : développement et validation d’un instrument de mesure intégrant un dispositif participatifBeaulieu, Marianne 05 1900 (has links)
Contexte : De manière générale, on considère que le processus de validation d’un instrument de mesure porte sur la validité et la fiabilité. Or, la nature dynamique et évolutive de certaines problématiques, comme la stigmatisation des personnes vivant avec le VIH (PVVIH), laisse croire qu’il est particulièrement important de réinvestir rapidement dans la pratique, les résultats produits par les mesures ainsi validées.
Objectifs : La présente thèse vise à développer et valider une échelle de mesure des attitudes stigmatisantes envers les PVVIH en intégrant un dispositif participatif. La thèse utilise en partie les données d’une enquête de surveillance des attitudes envers les PVVIH au Québec, elle comporte trois études qui répondent aux trois objectifs spécifiques suivants : (1) valider la version révisée d’un instrument de mesure des attitudes favorables à la stigmatisation dans la population générale du Québec envers les PVVIH; (2) analyser la relation entre la mesure des attitudes favorables à la stigmatisation et le recours au dépistage du VIH dans la population générale du Québec; (3) décrire et analyser les processus de circulation et d’utilisation des connaissances produites par l’instrument de mesure dans les réseaux professionnels des membres d’un comité consultatif.
Méthodes : Un comité consultatif réunissant plusieurs partenaires issus de différents milieux a été constitué dès l’obtention de la subvention. Il a été consulté et informé avant, pendant et après l’enquête téléphonique populationnelle (n=1500) ayant permis de colliger les données. L’Échelle des Attitudes Stigmatisantes envers les Personnes Vivant avec le VIH (EASE-PVVIH) a été validée au moyen de plusieurs analyses psychométriques : analyses factorielles exploratoires et confirmatives, corrélations, régression linéaire multiple, test-t, tests d’hypothèses d’invariance de la structure factorielle et alphas de Cronbach (objectif 1). L’association entre les attitudes favorables à la stigmatisation et le recours au dépistage du VIH a été testée à l’aide de régressions logistiques hiérarchiques (objectif 2). Quant aux processus de circulation et d’utilisation des connaissances dans les réseaux professionnels, ils ont été analysés au moyen d’une étude de cas rétrospective (objectif 3).
Résultats : Les analyses ont révélé trois résultats importants. Premièrement, d’un point de vue psychométrique, l’EASE-PVVIH est un outil fiable et valide pour mesurer les attitudes stigmatisantes envers les personnes vivant avec le VIH. Deuxièmement, sous une certaine forme caractérisée par l’inquiétude éprouvée lors de rencontres occasionnelles, les attitudes stigmatisantes par rapport aux personnes vivant avec le VIH semblent nuire au recours au test de dépistage dans la population générale au Québec. Troisièmement, un dispositif participatif en particulier, soit un comité consultatif, semble être un moyen pour favoriser le réinvestissement rapide et étendre la portée des résultats produits par la recherche dans des actions concrètes de santé publique.
Conclusion : Ces résultats mettent en lumière la portée d’un dispositif participatif pour la validation d’instrument de mesure. L’arrimage entre les préoccupations scientifiques et pratiques apparaît être une avenue prometteuse pour améliorer la qualité et la pertinence sociale des données produites par les mesures. / Background: A measurement scale is generally evaluated in terms of validity and reliability. However, the dynamic and evolutive nature of certain issues, such as the stigmatization of people living with HIV (PLHIV), suggests that it is particularly important to rapidly reinvest the knowledge into practice that has been obtained using validated measures.
Objectives: The purpose of this thesis was to develop and validate a scale to assess stigmatizing attitudes towards PLHIV by integrating a steering committee into the process. Part of this thesis uses the data collected from a survey of attitudes towards PLHIV in Quebec. Three studies were conducted to achieve the three following objectives: 1) to validate the revised version of a measurement scale to assess stigmatizing attitudes towards PLWHA in the general Quebec population; 2) to analyze the relationship between stigmatizing attitudes and HIV testing in the general Quebec population, and 3) to describe and analyze how members of a steering committee used and disseminated knowledge produced by a research project.
Methods: A steering committee made up of partners from various communities was formed once funding was obtained. The committee was actively involved before, during, and after the population telephone survey (n=1500) was conducted to collect the data. The Stigmatizing Attitudes towards People Living with HIV/AIDS Scale (SAT-PLWHA-S) was validated using psychometric analyses: exploratory and confirmatory factor analyses, correlations, multiple linear regression, t-tests, hypothesis testing of factorial structure invariance, and Cronbach’s alphas (objective 1). The association between stigmatizing attitudes and HIV testing were tested using sequential logistic regression (objective 2). The dissemination and use of knowledge among professional networks were analyzed using a retrospective case study (objective 3).
Results: The results revealed three significant findings. First, from a psychometric standpoint, the SAT-PLWHA-S is a valid and reliable instrument for measuring stigmatizing attitudes towards PLHIV. Second, one form of stigmatizing attitudes, concern about occasional contact with PLHIV, appeared to act as a barrier for HIV testing in the general Quebec population. Third, a steering committee appear to foster rapid translation of research results into concrete public health actions.
Conclusion: These results shed light on the contribution of a steering committee to the validation of a measurement scale. The joining of scientific and practitioners’ concerns appears to be a promising avenue for improving the quality and relevance of data generated by such measures.

Desenvolvimento e validação de escala da importância da imagem do país de origem (COI) como recurso na estratégia / Development and validation of a scale to measure the importance of country of origin image (COI), as a resource in the strategySutter, Mariana Bassi 13 September 2016 (has links)
A área de estratégia, por meio da teoria baseada em recursos (RBT), desenvolve estudos que procuram compreender as características, recursos, capacidades e processos que levam algumas empresas, na mesma indústria, a terem um desempenho melhor que seus concorrentes. A RBT atingiu a maturidade teórica exigindo novos rumos para a sua revitalização. Simultaneamente, os estudiosos de marketing internacional afirmam que a teoria sobre a imagem do país de origem (COI) precisa ser revigorada e recomendam que ela seja analisada à luz da literatura de estratégia. É sob essa perspectiva que esta tese apresenta a sua contribuição, desenvolvendo e validando uma escala de importância de COI na perspectiva empresarial. O construto foi desenvolvido com base em uma capacidade específica da empresa: a construção e gestão da marca. Para isso, as bases teóricas sobre RBT, interface entre RBT e marketing, COI e marca foram revisadas e, ancorada nesta literatura, foi possível identificar os processos para incorporar a COI na estratégia da marca, os quais foram utilizados como dimensões da escala. Foram realizados diversos procedimentos psicométricos seguindo as recomendações de diversos psicometristas. O constructo foi definido como a capacidade de gestão da incorporação da COI à marca (BCOI), que reflete a importância conferida pela empresa para usar a COI como um recurso na construção da capacidade de marca. Após a etapa inicial, em que foram gerados e validados os itens com pesquisadores e com gestores, realizou-se um levantamento com 457 executivos. A amostra foi dividida em duas subamostras para aplicação de diferentes técnicas estatísticas. Na subamostra 1 foi realizada uma análise fatorial exploratória que confirmou o modelo inicial da escala delineado junto a pesquisadores e gestores no processo de geração de itens. Esse modelo foi testado na subamostra 2 por meio da análise fatorial confirmatória e da modelagem de equação estrutural. Os resultados indicaram que a BCOI se manifesta por meio de 26 itens organizados em cinco dimensões: elementos textuais e visuais, sentidos, recursos culturais, recursos naturais e empregados / The strategy stream, through resource theory based (RBT), develops studies that seek to understand the characteristics, features, capabilities and processes that lead some companies in the same industry, to have a better performance compered to its competitors. The RBT has reached the theoretical maturity requiring new directions for its revitalization. Simultaneously, international marketing scholars claim that the theory about the country of origin image (COI) needs to be invigorated and recommend it to be examinated in the light of the strategy literature. It is from this perspective that this thesis presents its contribution by developing and validating a scale of importance of COI in business perspective. The construct was developed based on a specific capability of the company: building and manageming the brand (branding). For this, the theoretical basis of RBT, the interface between marketing and RBT, COI and branding were reviewed and anchored in this literature, it was possible to identify the processes to incorporate the COI in the brand strategy, which were used as scale dimensions. various psychometric procedures following the recommendations of several psychometricians were performed. The construct was defined as the branding capability of COI incorporation (BCOI), which reflects the importance given by the company to use the COI as a resource in brand building capability. After the initial stage, in which items were generated and evaluated with researchers and managers, a survey with 457 executives was held. The sample was divided into two subsamples for application of different statistical techniques. An exploratory factor analysis was performed with subsample 1. The EFA produced an initial scale model that was tested in subsample 2 through confirmatory factor analysis and structural equation modeling. The results indicated that the BCOI iis manifested through 26 items organized into five dimensions: textual and visual elements, senses, cultural resources, natural resources and employees.

Antécédents, manifestations et effets du Bien Vieillir Désiré sur la consommation des seniors / Antecedents, manifestations and effects of the Desired Aging Well and its influence on the consumption of senior peopleSengès, Eloïse 02 May 2016 (has links)
Enjeu important pour le marketing des seniors, le concept de bien vieillir demeure peu investigué par la recherche en marketing. Nous introduisons un nouveau concept, le Bien Vieillir Désiré (BVD), qui fait référence aux objectifs psychologiques, physiques, sociaux et financiers, poursuivis dans la quête du bien vieillir. Nous en proposons un modèle de mesure bifactoriel, fiable et valide, en quatre dimensions : le BVD général, le BVD physique, le BVD social et le BVD financier. Son influence est testée sur huit comportements de consommation relatifs aux secteurs suivants : alimentation, e-santé, chirurgie esthétique, loisirs, placements financiers, réseaux sociaux et sites de rencontres. L’échelle de mesure et un modèle global antécédents-manifestations-effets sont validés à partir d’un échantillon de 900 seniors âgés de 50 à 80 ans. Les résultats suggèrent le développement d’une nouvelle approche marketing des seniors : le marketing du bien vieillir. Son investigation et sa mise en œuvre sont ancrées dans quatre concepts clés : le BVD, le vieillissement perçu, les attentes d’ajustement au vieillissement et la consommation du bien vieillir. / Aging well is now a key stake for senior marketing, yet this concept remains little investigated by consumer research. A new concept is introduced in marketing research: Desired Aging Well (DAW), which refers to the psychological, physical, social and financial objectives, pursued in the quest for aging well. This research provides a reliable and valid bifactor measurement model for Desired Aging Well, in four dimensions: general DAW, physical DAW, social DAW and financial DAW. Its influence is tested on eight consumer behaviors related to the following sectors: food, e-health, plastic surgery, leisure, financial investments, social networks and dating sites. The Desired Aging Well scale and the overall antecedents-manifestations-effects model are validated on a sample of 900 French senior people aged from 50 to 80. The results suggest the development of a new marketing approach for seniors: aging well marketing. Its investigation and implementation are rooted in four key concepts: Desired Aging Well, perceived aging, adjustment to aging expectations and aging well consumption.
