Le travail et la famille sont souvent vus comme deux domaines en compétition pour le temps, l’énergie et l’attention des travailleurs. Pourtant, des synergies positives existeraient à l’interface entre ces deux domaines de vie. Plus particulièrement, le bien-être psychologique pourrait déborder positivement d’un domaine à l’autre. Des articulations théoriques réfèrent au débordement de bien-être psychologique (p. ex., Edwards et Rothbard, 2000 ; Greenhaus et Powell, 2006), mais très peu d’études se sont attardées à évaluer les mécanismes par lesquels les bien-être psychologiques au travail et dans la famille s’influencent mutuellement. Les études antérieures ne permettent pas de capter adéquatement le processus à l’intérieur duquel les mécanismes de débordement opèrent, et ce, pour deux raisons. D’une part, elles recourent à des concepts-valises qui englobent l’ensemble du débordement et éludent ainsi les mécanismes internes à celui-ci. D’autre part, elles utilisent des devis majoritairement transversaux qui ne permettent pas de capter le déploiement temporel des mécanismes à l’étude. L’objectif de la présente thèse est donc d’évaluer un ensemble de mécanismes pouvant expliquer le débordement de bien-être psychologique entre le travail et la famille. Le premier article évalue le rôle médiateur de la performance au travail dans la relation du bien-être psychologique dans la vie hors travail vers le bien-être psychologique au travail, mécanisme le plus universellement soutenu par les théorisations de l’interface travail-famille. Ainsi, l’article explore plus en profondeur ce mécanisme en l’évaluant selon deux conceptualisations du bien-être psychologique, ainsi que deux types de performance. Deux études ont été réalisées : l’une à deux temps de mesure séparés de 7,5 mois et l’autre mesurant des expériences journalières concomitantes. Les résultats confirment le rôle médiateur de la performance dans les deux cas et mettent en lumière les distinctions entre le débordement de bien-être cognitif et celui de bien-être affectif. Le deuxième article explore trois autres mécanismes de débordement : la satisfaction dans la vie (médiateur), la centralité du domaine d’origine dans l’identité et la force des frontières travail-famille (modérateurs). Des théorisations périphériques au thème du débordement travail-famille enrichissent la compréhension du processus de débordement du travail vers la famille et inversement. Six-mille-soixante-dix-sept jeunes travailleurs ont répondu à trois questionnaires séparés de 11 semaines chacun. Des analyses acheminatoires soutiennent le rôle médiateur de la satisfaction dans la vie. Par ailleurs, nous avons trouvé que plus un individu accorde d’importance à sa famille, plus sa satisfaction dans la famille influencerait positivement sa satisfaction dans la vie. Finalement, la force des frontières entourant la famille limiterait le débordement de bien-être psychologique du travail vers la famille. Cette thèse a pour principale contribution l’articulation de plusieurs propositions théoriques en un modèle cohérent de débordement de bien-être psychologique entre le travail et la famille, ainsi que son évaluation empirique. Nos études étayent la documentation précédente en recourant à des échantillons diversifiés et à des méthodologies rigoureuses. Les résultats de cette thèse présentent des implications pratiques pour les travailleurs, les organisations et la société. / Work and family are often considered as two domains competing for the time, energy and attention of workers. Positive synergies could nonetheless exist at the interface between these two life domains. Notably, psychological well-being could spillover from one domain to the other. Theoretical frameworks about the spillover of psychological well-being exist (e.g., Edwards & Rothbard, 2000; Greenhaus & Powell, 2006), but very few studies have evaluated the mechanisms through which work and family psychological well-being influence each other. Previous studies do not adequately capture the process within which spillover mechanisms operate for two reasons. On the one hand, they use global concepts encompassing the whole spillover process, thereby disregarding internal mechanisms. On the other hand, they mainly use cross-sectional designs which cannot capture the processual nature of the proposed mechanisms. The objective of this thesis is therefore to evaluate mechanisms that could explain work-family psychological well-being spillover. The first article evaluates the mediating role of work performance in the influence of psychological well-being outside of work on psychological well-being at work, the mechanism most supported by work-family interface theories. Hence, the article explores this mechanism in depth by evaluating it according to two psychological well-being conceptualizations, as well as two types of performance. Two studies were conducted: one using a two-wave design with a 7.5-month delay and the other measuring experiences on a given workday. Results support the mediating role of performance in both studies and shed light on the distinction between cognitive well-being spillover and affective well-being spillover. The second article explores three other spillover mechanisms: life satisfaction (mediator), originating domain identity centrality, and work-family boundary strength (moderators). Theoretical articulations peripheral to work-family spillover enhance the understanding of the spillover process from work to family and inversely. Six thousand seventy-seven young workers answered three questionnaires with a delay of 11 weeks between each measurement time. Path analyses support the mediating role of life satisfaction. Furthermore, we discovered that the more an individual considers family as an important life domain, the more its family satisfaction will positively influence its life satisfaction. Finally, home boundary strength appears to limit the psychological well-being spillover from work to family. The main contribution of this thesis is its articulation of different theoretical propositions in one consistent work-family psychological well-being spillover model, as well as its empirical evaluation. Our studies build on previous literature by tapping on diverse samples and rigorous methods. The results of this thesis show practical implications for workers, organizations, and society.

This sociological study investigates the effects of work stress on family dynamics. Job demands, like heavy workload and working overtime, could have an effect on family members to fulfill role obligations and vital family functions according to Parsons’s, Murdock’s and Merton’s functionalist theories. By employing qualitative research techniques, fifty in-depth interviews guided by an interview schedule are conducted. The three research questions or tentative hypotheses, based on the functionalist theory, are answered by the findings from the data gathered. An inductive strategy is used to gather and interpret data to eventually build new theory. Theory is grounded in the data, hence grounded theory. The findings are categorized in terms of the research questions and describe and explain how the family is affected when work stress is experienced by the employee and family member. Possible explanations are offered as to why this occurs. Recommendations for further research are also made. / Sociology / M.A. (Sociology)

The family roles and responsibilities are still allocated along the gender lines. Women assume primary child care and household roles despite working fulltime. They suffer from work-family conflict as they battle with these competing demands. A phenomenological approach was adopted for this study. The existing literature was used in defining work-family conflict, looking at different work-family theories; development of gendered defined roles, motherhood and demands brought on by women working fulltime. The semi-structured interview was used for data collection. The themes which emerged showed that women experience strong emotions associated with raising children whilst working. There is compromise on quality time dedicated in each role. Women assume sole custodian over their children’s upbringing. Women enter into a second shift after work. Having a career and children, is made easier through adoption of strong coping strategies and mechanisms. The conclusions and recommendations were made for future a research and organisational practices. / Industrial and Organisational Psychology / Thesis (M.A. (Industrial and Organisational Psycology))
