La présente thèse de doctorat porte sur la relation entre la perception de la justice organisationnelle, l’émission de comportements inadaptés au travail et la santé psychologique des individus au travail. En plus de développer un outil de mesure des comportements inadaptés au travail et d’entreprendre un processus de validation de celui-ci, le présent travail propose que les comportements inadaptés au travail puissent occuper un rôle soit protecteur ou explicatif dans la relation qui unit la perception de la justice organisationnelle avec la santé psychologique des individus au travail. Au sein de cette thèse, le premier article recense la documentation scientifique quant aux variables de la perception de la justice organisationnelle, de l’émission des comportements inadaptés au travail et de la santé psychologique des individus au travail, ainsi que les liens qui unissent ces variables. Aussi, les modèles conceptuels des rôles modérateur et médiateur des comportements inadaptés au travail sont proposés au sein de la relation entre la perception de la justice organisationnelle et la santé psychologique des individus au travail. Le deuxième article a pour objectif de développer un outil de mesure des comportements inadaptés au travail et de tester ses propriétés psychométriques. Ainsi, des analyses statistiques exploratoires et confirmatoires ont été effectuées. Afin d’appuyer la valeur critériée de l’outil proposé, une analyse corrélationnelle a été réalisée avec le critère de l’adaptation. Certaines valeurs psychométriques de l’outil sont validées par les résultats obtenus. Le troisième article examine empiriquement les modèles conceptuels des rôles anticipés des comportements inadaptés au travail dans la relation entre la perception de la justice organisationnelle et la santé psychologique des individus au travail. La perception de la justice organisationnelle a été vue sous les composantes distributive, procédurale, informationnelle et interpersonnelle. De son côté, la santé psychologique des individus a été observée par le biais des éléments du bien-être et de la détresse psychologique au travail. Les différentes analyses de régressions multiples hiérarchiques ont permis d’observer l’absence du rôle modérateur des comportements inadaptés au travail. Pour sa part, l’utilisation du test de Sobel a démontré la présence du rôle médiateur des comportements inadaptés au travail dans certaines relations. Plus exactement, celles-ci sont la relation entre la justice interpersonnelle et le bien-être psychologique au travail, la relation entre la justice interpersonnelle et la détresse psychologique au travail, ainsi que la relation entre la justice distributive et la détresse psychologique au travail. Finalement, la conclusion de la thèse présente une synthèse des résultats et expose les limites et pistes de recherches futures. / The present doctoral thesis treats of the relation between perception of organizational justice, emission of misbehaviours at work, and individuals’ psychological health at work. In addition to developing and undertaking a validation process for a measuring scale of misbehaviours at work, the present thesis proposes that these behaviours may occupy either a protective or an explicative role in the relationship that unites the perception of organizational justice with individuals’ psychological health at work. Within the thesis, the first article lists scientific literature concerning the perception of organizational justice, the emission of misbehaviours at work, and individuals’ psychological health at work. This article also includes a revue of links that unite the variables presently at study. Following this review, two conceptual models about possible roles played by misbehaviours at work in the relationship between perception of organizational justice and individuals’ psychological health at work are developed. More precisely, these models are conceptualisation of the moderating and mediating roles of inadequate work behaviours. The second article’s goal is the development of a measuring scale for misbehaviours at work and testing its psychometric proprieties. In this context, exploratory and confirmatory statistical analyses were made. Also, in order to support the criterion value of the proposed tool, a correlation analysis was made with the criteria of adaptation. The results showed that certain psychometric values were validated. The third article empirically examines the conceptual models developed about the possible roles played by misbehaviours at work in the relationship between perception of organizational justice and individuals’ psychological health at work. Organisational justice perception was analysed under distributive, procedural, informational and interpersonal components. As for individuals’ psychological health at work, it was observed through the psychological well-being and distress elements. The different multiple hierarchical regression analyses helped observe the absence of a moderator role for misbehaviours at work. Using the Sobel test showed the presence of a mediator role for misbehaviours at work in the relationship between the interpersonal organizational justice component and well-being, as well as psychological distress at work. This same test highlighted the mediator role of misbehaviours at work in the relationship between the distributive component of organizational justice and the psychological distress at work of individuals. Finally, the conclusion of this thesis presents a synthesis of the results and highlights the limits and future research ideas.

Over the past five decades, universities across the globe have been subjected to powerful forces of change that have impacted their definition, governance and funding structures, and managerial practices. In South Africa, the reform process was amplified by the country’s apartheid legacy and the political and socio-economic realities. Consequently, the transformation has resulted in the corporatisation of universities and the re-engineering of the academic profession into a managed profession that brought about a changed work environment with less secure conditions of employment, more expectations and increased work pressure, with diminished autonomy. The changed and changing South African higher education environment has had and continues to have its effects on academic employees’ well-being, health and morale. Limited research has investigated the sense of purpose and meaning and psychological health of academic employees. Moreover, there is an absence of empirical studies that have reported on the development and evaluation of a brief group-based meaning-centred intervention that focuses on both the sense of purpose and meaning, and psychological health of academic employees. The primary aim of the study was to first explore the meaning and/or meaning frustration embedded in the academic employee experience, in order to develop and empirically assess a brief group-based meaning-centred intervention in a higher education setting. The intervention was articulated from a logotherapy perspective of Viktor Frankl’s system of psychotherapy. An intervention mixed methods design, consisting of four interdependent phases, was used to pursue the aim of the study. The phase one qualitative single case study was used to explore and describe the sense of meaning and/or meaning frustration embedded in academic employees’ experiences. This was used as a means of developing and supporting the intervention that was implemented in the phase three quantitative quasi- experimental single-group pre/post test study. Phase two was thus an applied phase where the intentional mixing of the qualitative and quantitative phases took place. Likewise, phase four was an applied phase since it was used to draw conclusions based on the integration of the phase one findings and the phase three results. The results of the quantitative study indicated that the majority of academic employees who participated in the study had a sense of definite purpose and meaning (MPIL-post = 114.59, SDPIL-post = 18.04) and psychological health, despite the changed and changing HE landscape. The main finding suggests that a logotherapy brief group-based intervention, with a strong cognitive restructuring component, may have a positive impact on the sense of purpose and meaning of academic employees, whilst reducing the presence of symptoms of depression, post traumatic stress, binge eating and panic. The experience of purpose and meaning in work, and adaptive psychological coping, was related to academic employees’ sense of making a difference in students’ development, the appreciation they have received from students, their freedom of choice, their view of work as a calling, the unique benefits of working in HE, meaning beyond the meaning in the moment (ultimate meaning) and making a difference in colleagues’ (staffs’) lives. Llimitations in the study are noted and recommendations are made to formalise existential analysis as a research method of meaning informed organisational assessment. / Psychology / Ph. D.

The aim of this research is to develop guidelines for a psycho-educational programme to enhance the self-actualisation of retired people. To do this, an investigation was undertaken to determine how to enhance self-actualisation during retirement, through an understanding of the: • phenomenon of retirement; • concept of self-actualisation; • challenges that hamper adjustment and self-actualisation during retirement; • factors which assist retirees in overcoming challenges and achieving self-actualisation; and • the role of psycho-educational programmes in enhancing self-actualisation during retirement. The literature study sought to promote such an understanding through the investigation of writings and research findings. The qualitative investigation attempted to provide a contextual understanding of the above, through an exploration of the retirement experiences of a selected group of retirees living in George (and surrounding area), South Africa. The findings served as the basis for guidelines for a psycho-educational programme to enhance the self-actualisation of retired people. / Psychology of Education / M.Ed. (Guidance and Counselling)
