Spending your time „nurturing what is right‟ enables people to grow and negotiate the problems of life which is more than only fixing what is wrong. The World Health Organisation also defined well-being as more than not ill-being. Flourishing is an optimal state of well-being. The question is, „what is it that flourishers do different from non-flourishers?‟ Pharmacy students prepare themselves for a profession which is being bombarded with change; they are the pharmacists of tomorrow. Among them some students flourish and the others do not. This study aimed to look at possible pathways to flourishing that flourishers utilise. In this way the study addressed several gaps in the knowledge regarding flourishing: 1) The prevalence of flourishing among pharmacy students, 2) The role of demands and resources in flourishing of students, 3) The role of antecedent factors of basic psychological need satisfaction on the basic psychological need satisfaction of students and therefore in their flourishing, and 4) The use of positive affect regulation (an internal strategy) as a pathway to flourishing. A cross-sectional design was utilised. The study population was all the enrolled pharmacy students at the North West University during 2014. A convenience sample of 779 students participated. The measuring battery consisted of the Mental Health Continuum-Short Form (MHC-SF; Keyes, 2009), the Emotional Regulation Profile-Revised (ERP-R; Nelis, Quoidbach, Hansenne, & Mikolajczak, 2011), the Balanced Measure of Psychological Needs (BMPN; Sheldon & Hilpert, 2012), statements about the antecedents of basic psychological need satisfaction and statements about demands and resources, developed for the purpose of this study, and a demographic questionnaire. Structural equation modelling, invariance testing and latent class analysis were some of the statistical techniques used to analyse the cross-sectional data. Manuscript one addressed the prevalence of flourishing among pharmacy students as well as possible differences between the year groups. The manuscript also investigated the role of workload as a study demand and the lecturer as a study resource and the possible interaction between them in the flourishing of students. Year group as a possible moderator in the respective relationships between demands, resources, the interaction between them on the one hand and flourishing on the other, were also assessed. 40% of the group flourished whilst 57% was moderately healthy and 3% languished. The different year groups negotiated the demands and resources in their study environment differently in their path to flourishing. The possible pathways to flourishing in this context were identified as the use of lecturer support (a resource), especially when the workload (a demand) is high and the successful negotiation of workload over their four years of study. Manuscript two dealt with the impact of antecedent factors of basic psychological need satisfaction of pharmacy students on their basic psychological need satisfaction and therefore ultimately the influence of these contextual factors on their flourishing. The researcher wanted to determine whether there is a difference in the role(s) that family, peers, lecturers and workload play in the satisfaction of the students‟ basic psychological needs (relatedness, competence and autonomy). Year group as a moderator in these respective relationships was also investigated. Family and peers played the most important role in need satisfaction of students. However, lecturers can actively engage in supporting the need satisfaction of students, which would increase their levels of autonomous motivation and thereby their levels of flourishing. In manuscript three the use of internal strategies as pathways to flourishing were explored. Positive emotion regulation strategies have a positive relationship with well-being. However, a person can dampen or savour his or her positive emotions. The students were clustered into distinctive groups by means of a latent class analysis. Three distinctive groups were posterior identified based on the characteristics of group members, namely flourishers, languishers and moderately healthy students. Regression analyses of the three groups revealed that flourishers are the only group that most likely will utilise savouring positive emotion regulation strategies and refrain from utilising dampening positive emotion regulation strategies. Pathways to flourishing that flourishing pharmacy students utilise are therefore the use of savouring positive emotion regulation strategies and the non-use of dampening positive emotion regulation strategies.

L’objectif principal de cette thèse était de mettre en évidence l’évolution et l’orientation de la motivation intrinsèque et extrinsèque des élèves roumains tout au long du second cycle d’enseignement secondaire général. Depuis plusieurs années la théorie de l’autodétermination (Deci et Ryan, 1985b, 2000) a été utilisée afin de mieux comprendre le comportement des élèves en milieux scolaire. Ryan et Deci distinguent la motivation intrinsèque et la motivation extrinsèque qui diffèrent selon le type de récompense rattachée à l’activité. La théorie de l’autodétermination repose sur trois besoins psychologiques fondamentaux : l’autonomie, la compétence et la relation à autrui. Les déterminants psychologiques familiaux (parents), institutionnels (professeurs) et écologiques (système scolaire compétitif et évaluatif) sont aussi susceptibles d’influencer l’orientation motivationnelle de l’élève. Une première étude s’est attachée à analyser l’orientation et l’évolution de la motivation intrinsèque et extrinsèque. Les résultats présentent les élèves comme plus motivés extrinsèquement plutôt qu’intrinsèquement. De plus les deux formes de motivation diminuent tout au long de leur cursus scolaire. Une seconde étude s’est employée à mesurer le degré d’influence des trois besoins psychologiques sur la motivation intrinsèque des élèves. Les résultats ont montré que le besoin d’affiliation était le plus fortement corrélé positivement à la motivation intrinsèque. Les deux dernières études ont visé à mettre en évidence la relation entre le sentiment d’autonomie des élèves exercé par les parents et les professeurs et leur motivation intrinsèque. Les résultats confirment l’influence positive de ces deux déterminants sur la motivation intrinsèque des élèves. Enfin ces résultats seront discutés notamment sur le rôle des déterminants psychologiques dans cette recherche et dans le cadre des travaux sur la normativité de la motivation intrinsèque. / The main objective of this thesis was to highlight the evolution and direction of the intrinsic and extrinsic motivation of Romanian pupils throughout the second cycle of general secondary education. For several years the self-determination theory (Deci and Ryan, 1985b, 2000) was used to better understand the behavior of students in the school. Ryan and Deci distinguish intrinsic motivation and extrinsic motivation that vary by type of reward attached to the activity. Self-determination theory is based on three basic psychological needs: autonomy, competence and relatedness. The psychological determinants family (parents), institutional (college), and environmental (school system competitive and evaluative) are also likely to influence motivational orientation of students. A first study has sought to analyze the direction and evolution of the intrinsic and extrinsic motivation. The results show the students as more extrinsically motivated rather than intrinsically. In addition, both forms of motivation decrease throughout their school career. A second study aimed to measure the influence of the three basic psychological needs on the intrinsic motivation of students. The results showed that the need for affiliation was most strongly correlated positively to intrinsic motivation. Two recent studies have sought to highlight the relationship between perceived autonomy of students by parents and teachers and their intrinsic motivation. The results confirm the positive influence of these two determinants on the intrinsic motivation of students. Finally, these results will be discussed including the role of psychological determinants in this research and the work on the normativity of intrinsic motivation.

Le rôle des parents est essentiel dans les expériences sportives de leur enfant. Cependant, de nombreux exemples relatés par les médias ont montré que le soutien qu’ils apportent n’est pas toujours adapté. Face à ce constat, de plus en plus d’études se sont intéressées à l’influence des parents dans le sport. Leur investissement pourrait aider leur enfant à faire face aux exigences qui découlent de leur double projet sportif et scolaire. Ainsi, l’objectif de cette thèse était de comprendre et d’accompagner les parents d’adolescents sportifs de haut niveau. Un premier chapitre présente une revue de littérature sur le sujet. Ensuite trois chapitres détaillent le travail réalisé afin de répondre à l’objectif.Le deuxième chapitre a exploré quantitativement les comportements parentaux et leur influence sur certaines variables psychologiques des sportifs. Il a montré que l’investissement parental le plus adapté au développement du sportif correspond à un investissement modéré incluant des encouragements, et une pression et des comportements directifs peu fréquents de la part des deux parents. Le troisième chapitre a étudié qualitativement les antécédents de l’investissement parental. Les analyses ont révélé que les parents vivent différents facteurs de stress organisationnels, développementaux, compétitifs et personnels qu’ils perçoivent comme étant, pour la plupart, difficiles à gérer. Afin de faire face à ces inquiétudes, les parents s’appuient sur différentes stratégies qu’ils mettent eux-mêmes en place et sur des stratégies réalisées par la famille et la structure sportive. Cependant, selon eux, ces dernières ne sont pas toujours efficaces. Le quatrième chapitre présente une étude interventionnelle qui a évalué l’efficacité d’un programme d’accompagnement. Les résultats ont montré que le programme influence positivement les expériences des parents. Ils ont également mis en avant les difficultés rencontrées pour engendrer des modifications comportementales perceptibles par les sportifs.Au regard des résultats des six études réalisées auprès de 1595 parents et 919 sportifs, des perspectives de recherches sont discutées. Des recommandations pratiques permettant de favoriser un investissement parental adapté au développement du sportif sont également exposées / Parents play a crucial role in their child’s sporting experiences. However, many examples outlined from the media have shown that parental support is not always appropriate. Besides, researchers have currently focused on the influence of parents in sport. Their involvement could sustain their child to cope with the demands of their dual careers in sport and education. Thus, the objective of this thesis was to understand and support parents of elite adolescent athletes. The first chapter presents a literature review on the topic. Then, three chapters detail the studies completed to meet the objective.The second chapter quantitatively explored parents’ behaviors and their influence on specific psychological variables of athletes. It showed that the most appropriate parental involvement to the athlete’s development corresponds to a moderate involvement from both parents: encouragements, and few pressure and directive behaviors. The third chapter qualitatively examined factors inducing parental involvement. Analysis revealed that parents feel different organizational, developmental, competitive and personal stressors mainly perceived as being difficult to manage. In order to cope with these concerns, parents rely on various strategies that they themselves implement but also on strategies carried out by family and sport center. However, according to them, the latter are not always effective. The fourth chapter presents an intervention study that evaluated the effectiveness of a support program. The results showed that the program positively influences parents’ experiences. They also highlighted the difficulties to create parental behavioral changes perceptible by athletes.Based on results of the six studies conducted with 1595 parents and 919 athletes, new directions of research are discussed. Practical recommendations to foster an appropriate parental involvement to the athlete’s development are also shared

How does the satisfaction (or the lack of satisfaction) of the innate need to have meaningful interpersonal relationships affects behavioural self-regulation? How does having/lacking interpersonal relatedness impact one’s perception of future interpersonal relationships? This doctoral dissertation aimed to answer these two fundamental questions by integrating the views of two complementary theories, need to belong theory (NBT; Baumeister & Leary, 1995) and self-determination theory (SDT; Deci & Ryan, 1985, 2000). Using a series of two laboratory experiments and one longitudinal study, this thesis examined the effects of social exclusion and inclusion on satisfaction of basic psychological needs, self-determined motivation, and self-regulation of behaviours. In Study 1 (N=72), social exclusion and inclusion were manipulated in order to examine their effects on the satisfaction of the three basic psychological needs proposed by SDT, that is the needs for autonomy, competence, and relatedness. Findings from this first experiment revealed that social exclusion decreases satisfaction of the three needs, whereas social inclusion increases satisfaction of these needs when compared to the control condition. Furthermore, significant differences were found between the exclusion condition and the inclusion condition for the reported levels of satisfaction of the needs for competence and relatedness. The effects of social exclusion and inclusion on basic needs satisfaction were further investigated in Study 2 (N=70); also, the second study examined how self-determined motivation and behavioural self-regulation are affected. More specifically, it tested whether participants’ persistence at a laboratory task, as well as their intentions for a future peer interaction (intentions to compete against a peer participant and intentions to collaborate with a peer participant) are influenced by social exclusion and inclusion, through the meditating effects of basic needs satisfaction and self-determined motivation. The results suggested that social exclusion, via the effects of basic needs and motivation decreases peer collaboration, whereas social inclusion was shown to have an opposite effect on peer collaboration. The effect of condition via the mediating effects of basic needs satisfaction and motivation failed to predict persistence at the task and peer competition. Lastly, Study 3 (N=624) assessed naturally occurring social exclusion and inclusion in a population of junior high school students. This third study investigated the independent contributions of SDT and NBT in the prediction of academic motivation and high school dropout. Peer relatedness, perceived needs support from parents, and perceived needs support from teachers were examined as potential predictors of academic motivation and high school dropout. Findings suggested that peer relatedness plays an important role in the prediction of academic motivation, but, that perceived needs support from parents and perceived needs support from teachers are stronger predictors of that outcome. Results from this study also revealed that peer relatedness contributes to the prediction of high school dropout, beyond what can be explained by academic motivation, perceived needs support from parents, and perceived needs support from teachers. However, perceived needs support from parents was shown to be the most essential predictor of high school dropout. In sum, findings from this doctoral dissertation suggested that social exclusion has detrimental effects on one’s motivation and behavioural self-regulation. In contrast, social inclusion fosters social support which promotes satisfaction of the basic psychological needs, self-determined motivation, and successful self-regulation. This doctoral thesis contributed to the application of SDT and NBT by comparing elements of the two complementary frameworks. It also offered an original contribution to research on social exclusion and inclusion by examining their impacts on self-determined motivation, and basic needs satisfaction, as well as testing them in both the laboratory setting and the natural setting.

Results showed that the fulfillment of the three basic psychological needs is linked to intrinsic motivation and to self-regulated types of extrinsic motivation. All self-regulated motivational types were significant predictors of emotional engagement. Therefore results corroborate self-determination theory regarding the outcomes of motivational quality and that fulfillment of basic psychological needs matters. Significant relationships were also found between basic psychological needs satisfaction and grades students gave to their achievement in Portuguese. Results were discussed according to selfdetermination theory, and a new light was shed on our students’ motivational processes specific components and dynamics. Limitations of the study were pointed out.

La presente investigación tiene como objetivo explorar y describir cómo contribuye la relación de pareja en la satisfacción de necesidades psicológicas básicas (NPB) en un grupo de mujeres transexuales de Lima. Se abordó las NPB mediante un estudio cualitativo con diseño fenomenológico en seis casos de estudio. Se realizó una entrevista a semi estructurada por cada una de las seis mujeres transexuales residentes en Lima Metropolitana de nivel socioeconómico B y C que oscilaban entre los 26 y 61 años de edad. Los resultados indicaron que la relación de pareja logra tanto satisfacer como frustrar las NBP de las practicantes. Se concluyó que los procesos de satisfacción o frustración de las NBP de estas mujeres transexuales además de ser el resultado de una conducta de sus parejas, también pueden darse de forma combinada, creándose redes complejas donde la satisfacción de una necesidad puede llevar o esconde la frustración de otra u ocurrir de manera inversa. / The objective of this research is to explore and describe how couple’s relationship contributes to the satisfaction of psychological basic needs (PBN) on a group of transsexual women of Lima. PBN were approached through a qualitative study with phenomenological design in sex case studies. A semi-structured interview was conducted by each of the six transsexual residents of Metropolitan Lima of socioeconomic level B and C, who ranged between 26 and 61 years old. The results indicated that couple’s relationship achieves both satisfy and thwart the PBN of the participants. It was concluded that the process of satisfaction or thwart of the PBN of these transsexual women besides being the result of a behavior of their partners, can also occur in a combined way, creating complex networks where the satisfaction of a need can carry or hide the frustration of another or occur in reverse. / Tesis
