This research project explores whether the delivery of positive psychology interventions in the workplace through an employee assistance program (EAP) can improve employees’ authentic happiness/flourishing as well as decrease symptoms of depression. A small convenience sample of 13 Manitoba public school educators accessing employee assistance were recruited for a quasi-experimental research design. Nine participants were randomly assigned to the experimental group and the remaining participants assigned to the control. Experimental group members participated in a six session psychoeducational, experiential, and process-oriented positive psychotherapy group that met once a week over six weeks. Experimental group participants’ scores on the authentic happiness/flourishing measure increased by a statistically significant 9% and depression scores decreased by a statistically significant 45% from pre-intervention to one month post-intervention. The study’s findings therefore provide promising confirmation that positive psychology interventions delivered through EAPs can make a meaningful difference as both secondary prevention and primary enhancement strategies in the workplace.

The purpose of this study was to examine formal volunteering among retirees in order to explore whether their volunteer experiences represent an extension of their career in the paid workforce or whether their volunteer activities represent a completely new direction, and how this influences their career self-concept, as interpreted through Donald Super’s life-span, life-space theory of career development. This study employed a developmental mixed-method design. In Phase 1, qualitative interviews were conducted with 12 participants to better understand retirees’ volunteer experiences. Phase 1 informed the design of an instrument for the Phase 2 survey which examined the issues among a larger sample of 214 retirees. The Phase 2 results supported the Phase 1 findings and indicated that many retirees sought an extension of career in volunteer activities in that they used similar skills and knowledge. Study participants also displayed a desire for lifelong learning. Retirees relinquished their paid-work career, took on the retiree and volunteer roles, and integrated these roles within their career self-concept to create a new sense of self. These results indicated that the retirees had entered a new stage of life, qualitatively different from ‘retirement’. To better reflect the experiences of these retirees, it was proposed that Donald Super’s life-span, life-space theory of career development be extended to include Redirection. This theorizing is consistent with the finding that retirees both wanted to and are able to integrate previous paid work elements as well as seek out lifelong learning opportunities within their volunteer activities. This study demonstrates that the volunteer role in the lives of retirees can lead to personal renewal and reshaping of the career self-concept, or what is labeled as the stage of Redirection. This study also has implications for volunteer management, retirement planning and social policy, and may be of interest to volunteer managers, nonprofit organizations, career counsellors, financial planners, retirement planning consultants, life coaches and policy planners.

This study investigated the subjective well-being of female strippers. The effect that certain variables namely, self-esteem, general health, self-efficacy, perceived social support and sense of coherence had on subjective well-being and the independent components of subjective well-being, namely life satisfaction and positive and negative affect, were investigated. The sample consisted of 75 female strippers and was a consequence of a combination of purposive and convenience non-probability sampling. These women were employed at Teazers - a chain of strip clubs in Gauteng, South Africa. Information was gathered through self-reported questionnaires with quantifiable scales. The results of the regression models showed that life satisfaction depends on perceived social support, but positive and negative affect depends on self-esteem and general health. If life satisfaction and positive and negative affect is combined into a measurement of subjective well-being, 6.7% of the total variance in subjective well-being is uniquely explained by self-esteem. / Psychology / M.

Sammanfattning Syfte och frågeställningar Syftet med studien var att få en inblick i hur omfattande smartphoneanvändning var bland människor och hur denna användning samvarierade med den mentala hälsan. En annan del av syftet var att se om ett beteendemönster kunde ändras hos smartphoneanvändarna och på så vis ändra den mentala hälsan. För att uppnå syftet ställdes två frågeställningar: (1) Finns det något samband mellan grad av smartphoneberoende och upplevd psykisk hälsa? (2) Kan en kortare tids intervention där man begränsar användandet av smartphone hos deltagarna påverka deras subjektiva psykiska välmående? Metod För att få en inblick i hur utbrett smartphoneberoendet är i dagsläget och om det påverkar den subjektiva psykiska hälsan valdes enkät som metod eftersom det var tidseffektivt och gav ett brett urval. För att kunna skapa en beteendeförändring så behövdes en aktiv interaktion med respondenterna, därför kom beslutet att utföra en intervention. Interventionen gick ut på att deltagarna under sex dagar skulle reducera sitt mobilanvändande i största mån möjligt för att se om deras mentala hälsa kunde påverkas. Urvalet bestod av 76 kvinnor och 56 män med en medelålder på 25 år. Resultat Enligt korrelationsanalysen fanns ett svagt samband r = - 0,218 mellan mental hälsa och smartphoneberoende som var statistiskt signifikant (p = 0.013). Analys av enkätdata visade en stor grupp som klassades som smartphoneberoende = 48.2% och 51.8% som ej smartphoneberoende. Detta visade att fler personer är mobilberoende i detta urval än vad andra studier hittat. Interventionen bortgick på grund av ett stort bortfall. Slutsats Resultatet visade på ett svagt negativt samband mellan mental hälsa och smartphoneberoende. Kausalitetssamband klargjordes inte och vidare forskning krävs på ämnet för att i framtiden kunna urskilja om en mental ohälsa leder till mer smartphoneanvändande eller om mycket smartphoneanvändning leder till mental ohälsa i sig. / Abstract Purpose and objective The purpose of this study was to survey the use of mobile phones amongst people and how it coincides with mental health. We also wanted to investigate whether or not we could create a behavioral change amongst the mobile phone users and thereby see if it affected their mental health. To achieve this objective we emanated from two questions: (1) Is there a relationship between Smartphone addiction and subjective mental health? (2) Can a short intervention, where you decrease the time spent on smartphones amongst users improve their subjective well-being? Method To get an insight in how widespread the use of mobile phones is and if it affects subjective well-being we chose to collect data through surveys because it was time effective and gave a wide group of people. To be able to create a behavioral change we concluded we had to actively interact with the respondents, so we chose to perform an intervention. During the intervention the participants would reduce their mobile phone usage to the greatest extent possible to see if their mental health could be improved. Result According to the correlation analysis, there is a weak relationship r = - 0,218 between mental health and smartphone addiction which is statistically significant (p=0.013). Analysis of survey data showed a large group classified as smartphone addicted = 48.2% and 51.8% as non-smartphone addicted. This shows that more people are smartphone addicted in this study than other studies have found. The intervention failed due to many dropouts. Conclusions The result showed a weak negative correlation between mental health and smartphone addiction. Causal correlation was not clarified and further research is required on the subject in order to determine whether mental health issues leads to more smartphone usage or if a lot of smartphone usage leads to mental health issues by itself.

Se por um lado, a sua importância e inferência na performance dentro do contexto empresarial têm sido crescente, caracterizando a necessidade de um entendimento cada vez maior por parte das empresas, por outro, o investimento das corporações de grande porte, caminham cada vez mais em direção dos países com crescimento exponencial sustentado, como são o BRIC, o que cna uma necessidade fomentada de pesquisa nesta área de pesquisa para estas regiões. Este estudo pretendeu investigar, avaliar e mapear a influência do capital e do CCO na satisfação de vida e desempenho no trabalho do funcionário de nível superior, no contexto empresarial brasileiro e português, com o objetivo de identificar quais as diferenças existentes nestes duas realidade, devido ao investimento crescente do segundo para com o primeiro. Genericamente, encontramos clara influência das dimensões do CCO tanto para o desempenho no trabalho como para a satisfação de vida do trabalhador, assim como presença também marcada das duas dimensões do capital Social. Mais especificamente, foi entendido pelo nosso estudo que a realidade empresarial brasileira necessita que as empresas criem mecanismos que fomentem os laços entre colegas, a conscienciosidade, altruísmo e virtude cívica dos seus funcionários, pois assim aumentará o desempenho. Já para o contexto português, apenas a conscienciosidade e a virtude apresentaram significativa relação. Desta forma, conclui-se que para o investimento das empresas português no Brasil, estas precisam ter atenção à dimensão estrutural - relação com colegas - promovendo-a e à necessidade patente que os brasileiros têm de ajudar os seus colegas - comportamento altruísta - para aumentar o desempenho no trabalho. No que se refere a satisfação de vida, que se mostrou estreitamente relacionada com o desempenho, o brasileiro apenas precisa notar confiança nos colegas, senti-se altruísta e consciencioso, ao passo que o português necessita criar fortes laços com os colegas, mas não fomentar o comportamento altruístico. Desta forma as empresas investidoras apenas precisam ter atenção mais uma vez a necessidade de prestar ajuda especifica que o brasileiro sente, promovendo workshops com os próprios funcionários, por forma a estes passarem o seu conhecimento, monitorias, estágios, entre outros. Estes resultados demonstraram que cada continente, país (possuidor ou não da mesma língua) e/ou cultura comporta diferenças significativas no contexto empresarial, assim tornase difícil implementar técnicas e comportamentos internacionais e esperar que os resultados sejam exatamente iguais. Este estudo espera dar alguns instrumentos de comparação para que as empresas portuguesas entendam, a este nível, a realidade brasileira. / Since long ago, the themes of social capital and organizational citizenship behavior (OCB) have been extensively researched and studied in the V.S., though these have received little attention in terms of other international contexts. On the one hand, its importance and inference performance within the business environment have been increasing, characterizing the need for an increased understanding by firms, on the other hand, investment by large corporations, walk increasingly direction of countries with sustained exponential growth, as BRIC countries, which creates a need for research in this area encouraged the search for these regions. This study intended to investigate, assess and map the influence of capital and of the CCO in life satisfaction and job performance of top-Ievel employee in Brazilian and Portuguese business environment, in order to identify differences between those two realities, because increasing investment from the second to the first. Generally, we find clear influence ofboth dimensions ofthe CCO to perform at work and for the life satisfaction of workers, and also marked presence of the two dimensions of social capital. More specifically, it was understood by our study that the Brazilian business reality requires companies to create mechanisms that foster ties between colleagues, conscientiousness, altruism and civic virtue of its officials, as well as increase performance. As for the Portuguese context, the only virtue and conscientiousness showed a significant relationship. Thus, we conclude that for investment firms Portuguese in Brazil, they need to pay attention to the structural dimension - relationship with colleagues - promoting it and need to clear the Brazilians have to help their colleagues - altruistic behavior - to increase job performance. Regarding life satisfaction, which was closely related to performance, Brazilians need only belive in colleagues trust, I was unselfish and conscientious, whereas the Portuguese need to create strong bonds with colleagues, but not to encourage altruistic behavior. Thus investment firms only need to pay attention once again the need to assist states that the Brazilian feel, providing workshops with the employees themselves, so they pass their knowledge, tutoring, internships, among others. These results demonstrated that each continent, country (with or not possessing the same language) and / or culture involves differences in a business context, so it is difficult to implement technical and intemational behavior and expect that the results are exactly alike. This study hopes to give some means of comparison to understand that Portuguese firms at this leveI, the Brazilian reality.

The purpose of this research was to investigate the relationship between the cross-cultural adjustment of the expatriate spouse and their level of subjective well-being. Demographic factors were considered to identify life domains that may affect cross-cultural adjustment and subjective well-being respectively. The Spousal Adjustment Scale, Scale of Positive and Negative Experience, Satisfaction with life scale, and Flourishing scale were used in the study. A quantitative, cross-sectional survey design was used, and a purposive sample which consisted of expatriate spouses currently residing in Germany was approached (N=156). Descriptive and inferential statistical analyses were applied. The results yielded a statistically significant correlation between cross-cultural adjustment and subjective well-being of expatriate spouses and indicated statistically significant differences between demographic groups including language proficiency, dependents, time spent in host country, nationality, career sacrifice, and support network. It was concluded that there is a positive relationship between the cross-cultural adjustment of the expatriate spouse and their well-being and that various demographic factors can influence both constructs. / Industrial and Organisational Psychology / M.Comm.

This study assessed the effect of variables such as life satisfaction, self-rated health, social support and coping styles on subjective well-being. The level of subjective well-being was studied in a sample of Mexican elderly persons from the state of Yucatan in Merida (n = 122) with an age range of 60-93 years. The results in women show that coping styles predicts subjective well-being in negative affects. Moreover, self-perception of health, coping styles, and satisfaction with life are adequate predictors of the cognitive dimension of subjective well-being. Results in men show that satisfaction with life and coping styles predict the cognitive dimension of subjective well-being. Findings point to the importance of exploring psychosocial variables in older adults. / El presente estudio evaluó el efecto de las variables satisfacción con la vida, autopercepción de salud, apoyo social y estilos de enfrentamiento sobre el bienestar subjetivo. Se contó con una muestra de 122 adultos mayores mexicanos del Estado de Yucatán, en la ciudad de Mérida con un rango de edad de 60 a 93 años. Los resultados en mujeres muestran que los estilos de enfrentamiento son predictores del bienestar subjetivo en los afectos negativos. En cuanto a la dimensión cognitiva del bienestar subjetivo, la autopercepción de salud, los estilos de enfrentamiento y la satisfacción con la vida fueron predictores adecuados. En hombres, los resultados demuestran que la dimensión cognitiva del bienestar subjetivo fue predicha a partir de la satisfacción con la vida y los estilos de enfrentamiento. Los hallazgos muestran la importancia del profundizar y promover variables psicosociales en los adultos mayores. / Cette étude a évalué l’effet de la satisfaction de la vie, de l’auto-perception de la santé, du soutien social et des styles d’adaptation sur les variables de bien-être subjectif. Nous avons étudié le niveau de bien-être subjectif d’un échantillon de 122 Mexicains âgés de l’État du Yucatan, dans la ville de Mérida, âgés de 60 à 93 ans. Les résultats chez les femmes montrent que les styles d’adaptation sont des facteurs prédictifs du bien-être subjectif des affects négatifs, en termes de la dimension cognitive du bien-être subjectif, l’auto-perception de la santé, les styles de confrontation et de satisfaction avec la vie étaient des prédicteurs adéquats, tandis que chez les hommes, les résultats montrent que la dimension cognitive du bien-être subjectif est prévu de satisfaction de la vie et les styles d’adaptation. Les résultats montrent l’importance d’approfondir et de promouvoir les variables psychosociales chez les personnes âgées. / Este estudo avaliou o efeito de variáveis, satisfação com a vida, autopercepção de saúde, apoio social e estilos de coping no bem-estar subjetivo. o nível de bem-estar subjetivo foi estudado no estado de uma amostra de adultos mexicanos mais antiga do Yucatan em Merida (n = 122) com uma faixa etária de 60-93 anos. Os resultados em mulheres mais antiga mostram que os estilos de enfrentamento são preditores de bem-estar subjetivo em efeito negativo em termos da dimensão cognitiva do bem-estar de saúde subjetiva auto-avaliação, estilos e satisfação com a vida de enfrentamento foram preditores adequados em homens mais antiga resultados mostram que a dimensão cognitiva do bem-estar subjetivo está previsto a partir de satisfação com a vida e estilos de enfrentamento.

Être parent engendre son lot de frustrations (Dix, 1991). Pour rester de bons modèles d’autorégulation émotionnelle et comportementale pour leurs enfants, la façon dont les mères composent avec leurs émotions de colère est cruciale. Or, la documentation s’est davantage concentrée sur la façon dont les mères doivent soutenir les émotions de leurs enfants, sans égard à leurs propres vécus émotionnels (Eisenberg, Cumberland et Spinrad, 1998, Miller-Slough, Zeman, Poon et Sanders, 2016). En raison du nombre limité d’études conduites à ce jour sur la colère maternelle possiblement constructive, la présente thèse exploratoire se veut une étape préliminaire à l’élaboration d’un programme de recherche plus large. Le but général de la thèse se décompose en deux grands objectifs. D’une part, elle vise à explorer trois réponses alternatives aux manifestations destructives de colère (c.-à-d., suppression expressive, nommer la colère et rappeler les règles/attentes) et d’autre part, elle s’intéresse au rôle différentiel de la colère en la comparant aux effets des autres émotions maternelles susceptibles d’être vécues simultanément. La présente thèse inclut trois études à devis transversal dont les données proviennent d’un même échantillon composé de 145 dyades mère-enfant (enfants âgés entre 9 ans et 13 ans). La première étude compare trois réponses alternatives envisageables pour remplacer les manifestations destructives de colère. Les résultats suggèrent que nommer la colère, même lorsque ses formes plus hostiles sont contrôlées, ne représente pas une alternative viable puisqu’elle est associée à la présence de comportements symptomatiques chez les enfants. Cette réponse de colère est également liée négativement à la satisfaction de vie et à l’estime de soi des enfants. À l’inverse, les résultats indiquent que la suppression expressive ne semble pas non plus recommandable puisqu’elle est aussi liée à la présence de comportements symptomatiques. Finalement, rappeler les règles/attentes aux enfants est associée positivement à la satisfaction de vie et à l’estime de soi des enfants, ce qui suggère qu’elle pourrait être une alternative envisageable. La deuxième étude s’intéresse à des situations typiques de non-coopération et examine les relations entre les trois réponses alternatives aux manifestations destructives de colère (cette fois codées) et l’internalisation des règles chez les enfants, évaluée par quatre indicateurs d’internalisation (c.-à-d., compréhension des règles, importance perçue de la règle pour la mère, émergence de peur/inquiétude et types de régulation). Aucune relation significative ne fut cependant trouvée entre les réponses de colère et les variables à l’étude. La troisième et dernière étude explore les relations uniques entre la colère maternelle perçue par les enfants et des indicateurs d’internalisation des règles, en contrôlant pour les effets des autres émotions négatives pouvant être vécues simultanément à la colère (c.-à-d., tristesse, mépris, honte, attitude bienveillante). Les résultats montrent que la colère, lorsque la présence des autres émotions maternelles est contrôlée, est associée à une meilleure compréhension des règles chez les enfants, appuyant l’idée selon laquelle cette émotion aurait une fonction socialisatrice importante. Par ailleurs, la colère est également associée à une régulation externe, suggérant que cette émotion ne favorise pas l’autodétermination des enfants. Les relations entre les autres émotions et les indicateurs d’internalisation des règles sont également discutées dans cette étude. Pris dans leur ensemble, les résultats contribuent à la documentation portant sur la colère maternelle de multiples façons. Les implications théoriques, pratiques et cliniques sont discutées. / Being a parent can be highly frustrating (Dix, 1991). To remain a good model of emotional and behavioral self-regulation for their children, the way mothers cope with their anger is crucial. However, the literature has rather focused on how mothers should support their children's emotions, regardless of their own emotional experiences (Eisenberg et al., 1998, Miller-Slough et al., 2016). Due to the limited number of studies conducted to date on possible constructive maternal anger expression, this exploratory thesis is intended as a preliminary step in the development of a broader research program. The general aim of this thesis is divided into two main objectives. The first objective is to explore three alternative responses to destructive forms of anger (i.e., expressive suppression, naming anger and reminding rules and expectations), while the second is to examine the differential role of anger on children’s internalization of rules process, by comparing this emotion’s associations with those of other maternal emotions (i.e., sadness, contempt, shame, compassion). This thesis includes three cross-sectional studies, conducted using the same sample of mother-child dyads. In total, 145 dyads (children aged between 9 and 13 years old) participated in these studies. The first study compares three possible alternative responses to destructive manifestations of anger. The results suggest that naming anger, even when more hostile manifestations of anger is controlled, is not a recommendable alternative since it is associated with the presence of symptomatic behaviors in children. This anger response is also negatively linked to children's life satisfaction and self-esteem. Conversely, the results indicate that expressive suppression is also not recommendable since it is also linked to the presence of symptomatic behaviors. Finally, reminding children of the rules and expectations is positively associated with children's life satisfaction and self-esteem, suggesting that this anger response may be a possible alternative. The second study looks at a specific situation of non-cooperation and examines the relations between the three alternative responses to destructive manifestations of anger (this time coded) and children’s internalization of rules process, evaluated by four indicators (i.e., understanding the rules, perceived importance of the rule for the mother, child emotional load and types of regulation). No significant relation however emerges between the anger responses and the study variables. The third and final study explores the unique relations between perceived maternal anger (child report) and the same four indicators of internalization of rules, controlling for the effects of other negative emotions that are likely to be experienced simultaneously with anger. The results show that anger, when the other maternal emotions are controlled, is associated with a better understanding of the rules by children, supporting the idea that this emotion may have an important socializing function. Yet, anger is also associated with external regulation, suggesting that this emotion does not promote children's self-determination. The relations between other maternal emotions and the different indicators of internalization of rules are also presented. Taken together, the results of the present thesis contribute to the literature on maternal anger in multiple ways. These theoretical, practical and clinical implications are discussed.

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.
