Hopelessness and Related Variables among Cancer Patients in the Southern European Psycho-Oncology Study (SEPOS).

BACKGROUND: Although hopelessness has been studied in cancer, no data are available in non-English-speaking countries. OBJECTIVE: The authors sought to amass data from Southern European countries (Italy, Portugal, Spain, and Switzerland) in order to fill this void. METHOD: A group of 312 cancer patients completed the Mini-MAC Hopelessness subscale, the Hospital Anxiety and Depression Scale (HADS), the Cancer Worry Inventory (CWI), and a six-item Visual Analog scale (VAS) to measure intensity of physical symptoms, general well-being, difficulty in coping with cancer, intensity of social support from close relationships, leisure activity, and support from religious beliefs. RESULTS: Regression analysis indicated that HADS-Depression, VAS Maladaptive Coping and Well-Being, and the CWI explained 42% of the variance. CONCLUSION: Hopelessness in cancer patients seems not exclusively to correspond to depression, but is related to various other psychosocial factors, such as maladaptive coping, as well.

Hábitos e problemas do sono das crianças dos 2 a 10 anos

RESUMO: Enquadramento: O sono é cada vez mais reconhecido como um fator determinante na Saúde Infantil porque, quando desadequado, pode ter consequências na regulação emocional e do comportamento, nas funções cognitivas, no rendimento académico, na regulação do peso e no risco de lesões acidentais. Os hábitos e problemas do sono das crianças portuguesas não se encontram ainda bem caracterizados. Este conhecimento é importante para o desenvolvimento da investigação e para a promoção da saúde nesta área. Objetivos: Adaptar e validar o Children's Sleep Habits Questionnaire (CSHQ) para a cultura portuguesa; Caracterizar os hábitos de sono de uma amostra de crianças dos 2 aos 10 anos tendo em vista a obtenção de dados de referência; Estimar a prevalência dos problemas do sono na perspetiva dos pais; Avaliar se existem diferenças nos hábitos e problemas do sono entre as regiões de média-alta e baixa densidade populacional; Identificar potenciais consequências dos problemas do sono. Métodos: Foi realizado um estudo transversal, descritivo e correlacional. A versão portuguesa do questionário (CSHQ-PT) foi desenvolvida de acordo com as orientações previamente publicadas e validada numa amostra de 315 crianças dos 2 aos 10 anos. Para o estudo dos hábitos e problemas do sono, o CSHQ-PT foi distribuído aos pais de 2257 crianças recrutadas em 17 zonas de agrupamentos escolares (15 escolhidos de forma aleatória) das áreas da Grande Lisboa, Península de Setúbal e Alentejo, compreendendo zonas litorais e do interior, e de alta, média e baixa densidade populacional. Foram obtidos 1450 (64%) questionários válidos. Resultados: O CSHQ-PT mostrou propriedades psicométricas semelhantes às das versões de outros países e adequadas para a investigação. A avaliação dos hábitos de sono nos dias de semana mostrou que as crianças se deitam, em média, pelas 21h 44m (DP 38 min.). A necessidade da companhia dos pais para adormecer diminui com a idade, ocorrendo em 49% das crianças aos 2-3 anos e 10% aos 9-10 anos. O hábito de adormecer a ver televisão foi descrito em 15,8% das crianças. O tempo total de sono diário diminui com a idade, com uma diferença mais marcada dos 2 para os 3 anos e dos 3 para os 4 anos, quando a sesta se torna menos frequente. No fim de semana, 25% das crianças dormia pelo menos mais uma hora. As diferenças nos hábitos de sono entre regiões de média-alta e de baixa densidade populacional foram reduzidas, sem reflexo na duração média do sono. Considerando valores de referência de outros países, verificou-se que 10% das crianças estudadas tinha uma duração do sono dois desvios-padrão abaixo da média esperada para a idade. A prevalência dos problemas do sono na perspetiva dos pais foi de 10,4%, sem diferenças significativas entre classes etárias, subgrupos de nível educacional dos pais, nem entre zonas de média-alta e baixa densidade populacional. Estes problemas do sono mostraram-se associados, sobretudo, à duração do sono insuficiente, resistência em ir para a cama, dificuldade em adormecer sozinho, despertares noturnos frequentes e ocorrência de parassónias. A baixa prevalência de problemas do sono identificados pelos pais contrasta com cotações elevadas no CSHQ-PT que traduzem comportamentos-problema mais frequentes, que são bem aceites por alguns pais. O Índice de Perturbação do Sono foi mais elevado nas famílias com menor nível educacional. Em análise multivariada mostraram valor preditivo para a sonolência diurna: o tempo total de sono diário, a diferença da duração do sono noturno durante a semana e no fim de semana, a frequência de algumas parassónias e o hábito de adormecer a ver televisão. O rendimento escolar mostrou associação com os problemas do sono, que são mais frequentes nas crianças com dificuldades escolares e hiperatividade/problemas de atenção. A relação entre estas variáveis é complexa. Conclusões: Este estudo mostrou que os problemas comportamentais do sono e a privação de sono são frequentes na população estudada. Estes problemas têm consequências, uma vez que correspondem a uma frequência mais elevada de sintomas de sonolência diurna, por comparação com outros países. Perante este cenário, é muito importante reforçar a promoção de hábitos de sono saudáveis e continuar a estudar as consequências do sono desadequado nas crianças portuguesas. -----------ABSTRACT:Framework: Sleep is increasingly being recognized as important to Child Health, for inadequate sleep may impact behavioral and emotional regulation, cognitive functions, academic performance, weight regulation and the risk of accidental injuries. The sleep habits and sleep problems of Portuguese children are not well characterized. This knowledge is important to support further studies and health promotion actions. Objectives: Develop and validate a Portuguese version of the Children's Sleep Habits Questionnaire (CSHQ-PT); Characterize the sleep habits and problems in a sample of Portuguese children from the ages of 2 to 10 for future reference; Estimate the prevalence of parent-defined sleep problems; Assess whether there are differences in sleep habits and problems between regions of medium-high and low population densities; Identify potential consequences of sleep problems. Methods: We conducted a cross-sectional, descriptive and correlational study. The Portuguese version of the questionnaire (CSHQ-PT) was developed according to published guidelines and validated in a sample of 315 children from 2 to 10 years old (y.o.). In order to study sleep habits and problems we delivered the CSHQ-PT to 2257 children recruited from 17 school districts (15 were chosen randomly) in areas with low, medium and high population densities, including coastline and inland regions. 1450 (64%) valid questionnaires were obtained. Results: The CSHQ-PT demonstrated psychometric properties that were similar to the versions from other countries and adequate for research. The evaluation of sleep habits showed that on schooldays children go to bed, on average, at 21h 44m (SD 38 min.). The need of having the parent in the room at bedtime decreases with the age of the child, occurring in 49% of children with 2-3 y.o. and 10% of children between 9 and 10 y.o. The habit of going asleep while watching TV was reported in 15,8% of the children. Total sleep time diminishes with the age of the child, having a major decrease from 2 to 3 y.o. and from 3 to 4 y.o., along with less frequent naps. During the weekend, 25% of the children sleep at least one extra hour. Considering reference values from other series, we found that 10% of the children had a sleep duration two standard deviations below the mean for the age. The differences in sleep habits between regions of medium-high and low population densities are few, and there are no differences in average sleep durations. The prevalence of parent-defined sleep problems was 10.4%. There were no significant differences between age classes, parent education subgroups or between regions of medium-high and low population densities. These sleep problems were associated with insufficient sleep duration, bedtime resistance, difficulty in falling asleep alone, frequent night awakenings and the occurrence of parasomnias. The low prevalence of parent-defined sleep problems contrasts with high CSHQ scores meaning that problematic behaviors are more frequent, but acceptable to some parents. The Sleep Disturbance Score was higher in families with a lower educational level. In multivariate analysis, the following factors predicted the daytime somnolence score: total sleep time, the difference in night sleep duration between the weekend and school days, the frequency of some parasomnias and the habit of falling asleep while watching TV. School achievement showed a negative correlation with the sleep problems, which are more frequent in children with school difficulties and hyperactivity/attention problems. The relationship between these variables is complex. Conclusions: This study evidenced that behavioral sleep problems and sleep deprivation are common in our population. These sleep problems have consequences as they correspond to more symptoms of excessive daytime somnolence comparing to other countries. Therefore, we reinforce the importance of promoting healthy sleep habits and further study the consequences of inadequate sleep in Portuguese children.

Relationship between national culture, democracy and environmental performance: A panel data analysis

This paper demonstrates the significance of culture in examining the relationshipbetween democratic capital and environmental performance.The aim is to examine the relationship among scores on the Environmental Performance Index and the two dimensions of cross cultural variation suggested by Ronald Inglehart and Christian Welzel. Significantional interrelationships among democracy, cultural and environmental sustaintability measures could be found, following the regression results. Firstly, higher levels of democratic capital stock are associated with better environmental performance. Secondly importance to distinguish between cultural groups could be confirmed.

Product quality judgments in a two-sequence cue environment

Previous research demonstrated that the sequence of informational cues and the level of distraction have an impact on the judgment of a product’s quality. This study investigates the influence of the force behind the processing of these cues, working memory (WM). The results indicate that without distraction, consumers with low and high WM capacity (WMC) equally base their product evaluation on the first sequential cue. In the presence of a distractor, however, low WM individuals are no longer able to recall the initial cue, and thus derive their product judgment from the final cue. Moreover, evidence of intercultural differences in the perception of product related cues, and their aptitude for signaling a favorable product quality is provided.

Perceptions of aging across 26 cultures and their culture-level associates

College students (N = 3,435) in 26 cultures reported their perceptions of age-related changes in physical cognitive, and socioemotional areas of functioning and rated societal views of aging within their culture. There was widespread cross-cultural consensus regarding the expected direction of aging trajectories with (a) perceived declines in societal views of aging, physical attractiveness, the ability to perform everyday tasks, and new learning; (b) perceived increases in wisdom, knowledge, and received respect; and (c) perceived stability in family authority and life satisfaction. Cross-cultural variations in aging perceptions were associated with culture-level indicators of population aging, education levels, values, and national character stereotypes. These associations were stronger for societal views on aging and perceptions of socioemotional changes than for perceptions of physical and cognitive changes. A consideration of culture-level variables also suggested that previously reported differences in aging perceptions between Asian and Western countries may be related to differences in population structure.

Psychometric properties of the Marlowe-Crowne Social Desirability Scale in eight African countries and Switzerland

The purpose of this study was to assess the cross-cultural validity of the Marlowe-Crowne Social Desirability scale short form C, in a large sample of French-speaking participants from eight African countries and Switzerland. Exploratory and confirmatory analyses suggested retaining a two-factor structure. Item bias detection according to country was conducted for all 13 items and effect was calculated with R2. For the two-factor solution, 9 items were associated with a negligible effect size, 3 items with a moderate one, and 1 item with a large one. A series of analyses of covariance considering the acquiescence variable as a covariate showed that the acquiescence tendency does not contribute to the bias at item level. This research indicates that the psychometric properties of this instrument do not reach a scalar equivalence but that a culturally reliable measurement of social desirability could be developed.

Gender stereotypes of personality : universal and accurate ?

Numerous studies have documented subtle but consistent sex differences in self-reports and observer-ratings of five-factor personality traits, and such effects were found to show well- defined developmental trajectories and remarkable similarity across nations. In contrast, very little is known about perceived gender differences in five-factor traits in spite of their potential implications for gender biases at the interpersonal and societal level. In particular, it is not clear how perceived gender differences in five-factor personality vary across age groups and national contexts and to what extent they accurately reflect assessed sex differences in personality. To address these questions, we analyzed responses from 3,323 individuals across 26 nations (mean age = 22.3 years, 31% male) who were asked to rate the five-factor personality traits of typical men or women in three age groups (adolescent, adult, and older adult) in their respective nations. Raters perceived women as slightly higher in openness, agreeableness, and conscientiousness as well as some aspects of extraversion and neuroticism. Perceived gender differences were fairly consistent across nations and target age groups and mapped closely onto assessed sex differences in self- and observer-rated personality. Associations between the average size of perceived gender differences and national variations in sociodemographic characteristics, value systems, or gender equality did not reach statistical significance. Findings contribute to our understanding of the underlying mechanisms of gender stereotypes of personality and suggest that perceptions of actual sex differences may play a more important role than culturally based gender roles and socialization processes.

Creating a global consciousness throught the driver model of curriculum development

The purpose of this study was to investigate the effect a human link through the One World Youth Project has on a global education program, if a human connection through the program enhances a student's ability to develop a critical consciousness of global issues, and the etTectiveness of thc constructivist-based Driver Model of Curriculum Development, which served as the curriculum model in this study. An action based research cycle was chosen as this study's research methodology and incorporated 5 qualitative data collection instruments: a) interviews and questionnaires, b) artifacts, c) teacher journal, d) critical friend's observation forms, and e) my critical friend's postobservation interviews. The data were conected from 4 student participants and my critical friend during all stages of the action research cycle. The results of this study provide educators with data on the impact of human connections in a global education program, the effects these connections have on students, and the effectiveness of the Driver Model of Curriculum Development. This study also provides practical activities and strategies that could be used by educators to develop their own global education programs. The United Nations drafted the Millennium Development Goals in an effort to improve the lives of billions of people across the globe. The eight goals were developed with the support of all member nations since all human beings are global citizens who have a responsibility to make the world a better place. Students need to develop a critical consciousness of global issues so that they can work with others to eliminate them. Students who are taught to restate the opinions of others win not be prepared to inherit a world full of challenges that will require new innovative ideas to foster positive change.

Global Education in the Shifting Classroom: Refocusing the Teacher Lens Through Study Abroad

Academic exchange programmes provide opportunities for teacher candidates to study at educational institutions abroad wherein they are able to learn more about different cultures, teaching practices, and build cross-cultural relationships. This paper is an exploration into my teacher candidate experience abroad. The relevant research on this topic indicates that teacher certification should take an active role in creating opportunities for teacher candidates to participate in educational experiences abroad because of their benefits. The knowledge that a teacher gains through abroad experiences is one of the strongest factors in helping to build authentic global classrooms. In addition, these programmes allow for fuller understanding of a global context and the chance to understand someone else’s story. This review and synthesis of literature and research findings prepares a foundation for how teacher candidates, and hopefully, how policy makers can work toward creating a more inclusive global classroom for students.

One of Us or One of Them: A Generic Qualitative Study on the Efficacy of the Funds of Knowledge Strategy to Reduce Teacher Ethnocentrism

The purpose of this study was to examine whether English a Second Language (ESL) instructors’ ethnocentrism could be reduced using multicultural education (MCE) principles. There were three focus group discussions and a Likert scale questionnaire. The findings demonstrated that while ESL instructors were conscious of systemic barriers, media stereotypes, and bullying, more diversity training is required in order to improve teachers’ attitudes, responses, and instructional strategies regarding integration issues due to the increasing diversity of learners present in classrooms today. The findings of the study also demonstrated that MCE principles could be used to effectively raise the awareness of ESL instructors when dealing with integration and assimilation issues. When immigration, human rights, and multicultural policies were examined critically, ESL instructors were able to improve their cross-cultural skills in the classroom to be more inclusive towards diverse ethnic groups by giving learners greater opportunities to express themselves. As a result, learners’ knowledge, experience, and skills were validated in the classroom leading to a more meaningful learning experience.

Engagement affectif, comportemental et cognitif des élèves du primaire dans un contexte pédagogique d’intégration des TIC : une étude multicas en milieux défavorisés

Réalisée en milieux défavorisés, cette étude porte sur l’engagement scolaire des élèves de troisième cycle du primaire (5e et 6e années au Québec) dans un contexte d’utilisation pédagogique des technologies de l’information et de la communication (TIC). L’objectif de cette recherche est d’analyser l’engagement d’élèves utilisant les TIC. Elle vise à décrire les pratiques pédagogiques d’intégration des TIC de dix enseignants, de relater la qualité de l’engagement de leurs 230 élèves lors de tâches TIC et de mesurer l’évolution et la qualité de leur engagement scolaire selon le degré de défavorisation de leur école. Pour ce faire, cette recherche s’est inspirée d’un cadre de référence traitant l’engagement scolaire selon les dimensions affective, comportementale et cognitive. De plus, cette étude multicas essentiellement de nature interprétative et descriptive a utilisé une méthodologie mixte de collecte et d’analyse des données. Les résultats montrent notamment que les enseignants accordent une valeur pédagogique importante aux TIC tant dans la fréquence de leur utilisation, dans les usages valorisés que dans la façon de les intégrer en classe. Les enseignants privilégient largement le traitement de texte et la recherche sur Internet, mais très peu d’autres usages pertinents sont mis de l’avant de manière soutenue. La majorité des enseignants interrogés préférerait se servir de quatre ordinateurs en classe pour utiliser les TIC plus facilement que d’avoir uniquement accès au laboratoire de leur école. De plus, ils perçoivent de manière unanime que l’utilisation des TIC exerce une influence importante sur la dimension affective de leurs élèves lors d’activités préparées, assez bonne sur la dimension comportementale et plus discutable sur la dimension cognitive. Plus globalement, les élèves eux-mêmes affichent en général un engagement scolaire relativement élevé. En six mois, la qualité de l’engagement affectif des élèves est restée stable, leur engagement comportemental a progressé, mais leur engagement cognitif a baissé légèrement. Les résultats montrent aussi que la qualité de l’engagement des élèves de milieux défavorisés évolue différemment selon le degré de défavorisation de leur école. Dans cette recherche, l’importance de l’utilisation des TIC sur la qualité de l’engagement est marquante et s’avère parfois meilleure que dans d’autres types de tâches. Sans pouvoir généraliser, cette étude permet aussi de saisir davantage la qualité et l’évolution de l’engagement scolaire des élèves de la fin du primaire en milieux défavorisés. Des recommandations pour le milieu et des pistes de recherches futures sont présentées en tenant compte des limites et des forces de cette thèse inédite réalisée par articles.

La politesse dans la communication interculturelle : les stratégies de politesse utilisées par les coréens apprenant le français comme langue seconde lors des situations de demande

La présente recherche a pour objectif d’examiner les stratégies de politesse utilisées par des apprenants coréens qui apprennent le français comme langue seconde lors des situations de demande et de mettre en évidence le rôle de la L1 et de la culture d’origine des apprenants quant à leurs choix des stratégies de politesse en français. Trois groupes de répondants ont participé à la recherche : 30 locuteurs natifs coréens qui habitent à Séoul, en Corée, 30 étudiants coréens apprenant le français comme langue seconde à Montréal, au Canada, et 30 locuteurs natifs francophones habitant Montréal. Les données recueillies auprès des locuteurs natifs ont servi de bases de données reflétant respectivement les normes de la L1 et celles de la langue cible. Pour la collecte de données, nous avons utilisé quatre outils : le Discourse Completion Test (DCT) écrit, des échelles d’évaluation des variables contextuelles, un Questionnaire à choix multiples (QCM) ainsi qu’une entrevue semi-structurée. Les réponses obtenues au DCT écrit ont été analysées à l’aide du schéma de codage élaboré dans le cadre du Cross-Cultural Speech Act Realization Project (CCSARP) (Blum-Kulka, House, & Kasper, 1989). Les résultats de notre recherche ont démontré que les apprenants coréens ont estimé les variables contextuelles, comme l’intimité et le pouvoir social ressentis vis-à-vis de l’interlocuteur dans les situations de demande de façon similaire aux locuteurs natifs francophones, alors qu’ils ont eu tendance à estimer une plus grande gravité d’imposition de la demande que les deux groupes de locuteurs natifs dans plusieurs situations de demande. Quant aux stratégies de demande, tandis que ce sont les stratégies indirectes qui ont été le plus fréquemment utilisées par les apprenants coréens et les locuteurs natifs francophones, les apprenants coréens ont montré une tendance au transfert pragmatique de la L1, en recourant aux stratégies directes plus fréquemment que les locuteurs natifs francophones. De plus, étant donné que les apprenants coréens ont utilisé beaucoup moins d’atténuateurs que les locuteurs natifs francophones, leurs formules de demande étaient plus directes et moins polies que celles employées par les locuteurs natifs francophones. En ce qui concerne les mouvements de soutien (supportive moves), les apprenants coréens se sont démarqués des deux groupes de locuteurs natifs, en recourant plus fréquemment à certaines catégories de mouvements de soutien que les autres répondants. Les analyses de corrélation entre l’estimation des variables contextuelles et le choix des stratégies de politesse nous ont permis de constater que les apprenants coréens ainsi que les locuteurs natifs francophones ont eu tendance à utiliser davantage d’atténuateurs lorsque le locuteur possède moins de pouvoir social. Les implications des résultats pour l’enseignement et l’apprentissage des aspects de la politesse dans la classe de français langue seconde ont été exposées.

Adaptation transculturelle et validation du questionnaire Upper Limb Functional Index (ULFI) pour la population canadienne française

Les troubles musculo-squelettiques du membre supérieur (TMS-MS) peuvent avoir un impact négatif sur l'autonomie d’une personne. À ce jour, il n’existe pas d’outils en français évaluant les limitations d'activités et les restrictions de participation, disposant de bonnes propriétés métrologiques et d'applicabilité dans un contexte clinique marqué par des contraintes de temps. L’Upper Limb Functional Index (ULFI), qui présente de bonnes qualités métrologiques et applicabilité clinique adéquate, s'avère un outil intéressant pour les ergothérapeutes de par son approche centrée sur la personne. Toutefois, il n'était disponible qu'en anglais et en espagnol. La présente recherche, constituée de deux études, visait à adapter l’ULFI à la population canadienne française et à évaluer ses propriétés métrologiques et son applicabilité clinique. La première étude a examiné sa cohérence interne, sa validité convergente et son applicabilité clinique auprès de 50 patients bilingues atteints de TMS-MS. La seconde étude visait à analyser sa fidélité test-retest et sa sensibilité au changement auprès de 60 patients francophones. Les résultats ont révélé que l'ULFI-CF possède des propriétés métrologiques solides : une cohérence interne élevée (α de Cronbach = 0,93), une excellente fidélité test-retest (CCI = 0,87-0,95), une excellente validité convergente (r = 0,70-0,85) et une sensibilité au changement de bonne à excellente (tailles d'effet = 0,49-0,88 et r = 0,64 pour la section 1). L'ULFI-CF démontre également une bonne applicabilité clinique. En conclusion, l’ULFI-CF s’avère un outil pertinent pour les cliniciens œuvrant auprès d’une clientèle canadienne française souffrant d'un TMS-MS dans un contexte clinique marqué par des contraintes de temps.

Nature humaine, pouvoir et compétence : une analyse comparative du statut chez les chasseurs-cueilleurs

Chez l'être humain, le pouvoir d'influence peut être accordé volontairement aux individus qui se démarquent par leurs habiletés exceptionnelles. Dans cette étude, deux théories issues de la perspective évolutionniste sur ce type de pouvoir sont confrontées : celle de la transmission sociale de l'information (Henrich et Gil-White 2001) et celle de l'échange social (Chapais 2012). Cinq hypothèses principales sont extraites et mises à l'épreuve : 1) la compétence supérieure de certains individus leur permet d'acquérir un statut supérieur; 2) la compétence d'un individu est évaluée par comparaison sociale et par l'intermédiaire de mécanismes psychosociaux; 3) les experts sont utiles à autrui puisqu'ils sont de meilleurs modèles à imiter et de meilleurs partenaires de coopération; 4) ces experts reçoivent de la déférence de leurs admirateurs en échange d'un partenariat avec eux ; 5) conséquemment, une compétition pour l'acquisition d'un statut supérieur émerge via la démonstration publique de la compétence et la recherche d'une réputation favorable. Ces prévisions sont testées par une analyse comparative de la littérature ethnographique portant sur dix sociétés de chasseurs-cueilleurs relativement égalitaires en utilisant la base de données du eHRAF of World Cultures. Les résultats appuient très fortement toutes les prévisions et indiquent que des asymétries de statut sont omniprésentes chez tous les peuples de l'échantillon, ce qui refléterait l'universalité des propensions psychosociales qui sous-tendent ces inégalités.

La santé psychologique au travail : une modélisation ancrée dans la théorie de la conservation des ressources

Si la santé psychologique au travail retient de plus en plus l’attention de la communauté scientifique et des milieux de pratique, certains aspects du phénomène restent néanmoins à explorer. Notamment, les études se sont peu attardées au fonctionnement de l’individu dans l’organisation, focalisant plutôt sur les expériences subjectives associées au bien-être et à la détresse psychologiques. En outre, l’état des connaissances sur les mécanismes sous-jacents à la santé psychologique au travail demeure embryonnaire. Faute d’écrits sur la question, la compréhension du construit s’avère partielle. Devant ce constat, la présente thèse vise à modéliser la santé psychologique au travail en y intégrant des indicateurs du fonctionnement de l’employé. Dans cette optique, cinq études, regroupées en deux articles, ont été menées auprès de quatre échantillons indépendants (Article 1 : NA = 296, NB = 350, NC = 139; Article 2 : NB = 330, NC = 128; ND = 389). Le premier article a pour objet de développer une conceptualisation et une mesure du fonctionnement de l’individu dans l’organisation. Prenant appui sur les travaux en socialisation organisationnelle et sur la théorie de la conservation des ressources (Hobfoll, 1989, 2001), l’ajustement cognitif au travail est proposé à titre d’indicateur additionnel de la santé psychologique au travail. Des analyses factorielles exploratoires et confirmatoires, de même que des analyses de cohérence interne, d’invariance temporelle et de régression, confirment les qualités psychométriques de l’instrumentation et étayent la validité de l’ajustement cognitif au travail comme indicateur de la santé psychologique au travail. Le second article s’appuie sur la conceptualisation du fonctionnement de l’employé présentée dans le premier article pour tester une modélisation de la santé psychologique au travail. Se fondant sur la théorie de la conservation des ressources (Hobfoll, 1989, 2001), la santé psychologique au travail est modélisée comme un processus incluant quatre indicateurs, soit le bien-être psychologique, la détresse psychologique, l’ajustement cognitif et les réponses comportementales de stress au travail. Deux mécanismes distincts sont mis de l’avant pour expliquer les relations unissant les indicateurs positifs de santé psychologique au travail (c.-à-d., le bien-être psychologique et l’ajustement cognitif) et celles caractérisant les indicateurs négatifs (c.-à-d., la détresse psychologique et les réponses comportementales de stress). Des analyses acheminatoires et d’invariance transculturelle révèlent la présence des deux mécanismes et montrent que, au-delà de l’influence des demandes en emploi, le bien-être psychologique exerce un effet médiateur sur la relation positive entre des ressources personnelles (c.-à-d., optimisme et résilience) et organisationnelle (c.-à-d., climat de travail) et l’ajustement cognitif au travail. Les résultats mettent également en exergue le rôle médiateur de la détresse psychologique sur la relation négative entre les mêmes ressources et les réponses comportementales de stress au travail. Une discussion générale précise la portée des résultats présentés dans le cadre des deux articles.
