Sommaire Cette thèse examine les liens entre la présence de risques suicidaires chez les adolescents et leur perception des pratiques de chacun de leurs parents. L’étude a examiné l’association entre le comportement suicidaire et différents aspects des pratiques parentales incluant l’affection, l’exercice du contrôle comportemental et psychologique ainsi que les conflits entre parent et adolescents. La thèse a également examiné l’effet du statut matrimonial des parents sur le comportement suicidaire chez les jeunes. Le dernier objectif de l’étude a été d’explorer le rôle du sexe de l’adolescent comme facteur de vulnérabilité face au suicide. L’échantillon de l’étude était composé 1096 adolescents Montréalais, âgés de 11 à 18 ans. L’échantillon était également réparti entre filles et garçons, fréquentant deux écoles secondaires de la région de Montréal, dans la province du Québec au Canada. Il y avait deux groupes à l’étude : le groupe suicidaire et le groupe non-suicidaire. Le premier groupe incluait les sujets présentant des idéations suicidaires et ceux ayant fait une ou plusieurs tentatives de suicide. Un questionnaire auto-rapporté fut administré à chaque sujet pour évaluer les dimensions suivantes auprès de la mère et du père : le niveau de proximité affective, le niveau de supervision parentale, le contrôle comportemental et le contrôle psychologique, la tolérance à l’égard des amis, ainsi que la fréquence et l’impact émotionnel des conflits. Une échelle a également évalué la présence éventuelle de comportements suicidaires chez les jeunes. Dans le but de tester l’hypothèse de base de l’étude, une série d’analyses descriptives et une MANCOVA ont été réalisées. L’hypothèse générale de la thèse postulant que les adolescents ayant des risques suicidaires présenteraient des relations plus problématiques avec leurs parents fut confirmée. En contrôlant l’effet de la détresse psychologique des adolescents, les analyses ont mené à la conclusion que, dans les familles biparentales, un faible niveau de proximité affective avec la mère, une fréquence plus élevée de conflits avec la mère, un excès du contrôle psychologique et un plus faible niveau de supervision maternelle, présentaient des liens significatifs avec le comportement suicidaire chez les adolescents. Indépendamment de la structure familiale, les caractéristiques suivantes du père étaient respectivement perçues par l’adolescent comme ayant des liens significatifs avec le comportement suicidaire des adolescents: faible proximité affective, impact émotionnel et fréquence élevée des conflits ainsi que le manque de supervision. Ces résultats ont été interprétés à la lumière des théories de la socialisation qui mettent l’accent sur le rôle central de la qualité des liens affectifs entre parents et adolescents, comme facteur de protection contre les risques suicidaires. Les résultats ont aussi révélé que les filles adolescentes sont plus exposées aux risques suicidaires tels que tentatives et idéations suicidaires. Les conclusions de cette étude soulignent le besoin urgent de recherches plus poussées sur le comportement suicidaire des adolescents et leurs liens avec les facteurs familiaux, en tenant compte du statut matrimonial des parents. La thèse met également l’accent sur la nécessité de mettre en place des programmes de prévention auprès des adolescents présentant des risques suicidaires élevés. / Abstract This thesis explores the relationship between the risk of suicidal behaviour in adolescents and their perception of parental practices used in their families. This study is primarily aimed at investigating the association between suicidal behavior in a Montreal sample of adolescents and several aspects of their parents’ parental practices including parent-child bonding, parental psychological and behavioral control, and parent- adolescent conflict. The second goal of this thesis was to examine the effect of parents’ marital status on adolescents’ suicidal behavior. The final objective of this study was to explore the link between gender difference and vulnerability to suicidal behavior in adolescents. The participants of this study included 1096 Montréal high school students, aged between 11 and 18 years, equally divided in boys and girls, in the province of Québec, Canada. There were two groups involved in this study: non suicidal and suicidal behavior. The suicidal behavior group included both suicidal ideation and suicide attempt behaviors. A self-report questionnaire was administrated to evaluate the level of parent and child bonding, the quality of parental psychological and behavioral control, and the level of adolescent’s conflict with each of the parents and risk of suicide in young individuals. A series of descriptive analysis and a multivariate analysis of covariant (MANCOVA) was performed in order to test the hypotheses of the study. The general hypotheses of the study postulating that adolescents who perceived a more troubled relationship with their parents, were at a higher risk of suicidal behaviors were confirmed. The evaluation of parental practices characteristics after being controlled for psychological distress and family structure concluded that in the case of intact families the high emotional impact and frequency of conflict with the mother, lack of maternal emotional bonding, excess of maternal psychological control, and lack of maternal supervision are significantly related to adolescents’ suicidal behaviors. In both families structures, the strongest significant characteristics of paternal parental practices perceived by adolescents with suicidal behavior was the lack of emotional bonding between father and child, the high impact and frequency of conflict between them, and lack of paternal supervision respectively. These results are interpreted in the light of socialization theory which emphasizes on the crucial role of the quality of the parent- adolescent bonding as a protective factor against suicidality in adolescents. The result also revealed that adolescent girls are at a higher risk of demonstrating suicidal behaviors such as ideation and attempt than boys. The findings of this study demonstrate an urgent need for more research on adolescent’s suicidal behavior and risk factors especially on parents’ marital status. The study also highlights the necessity of designing prevention programs specifically aimed at adolescents with an elevated risk of suicide.

English text with English, Northern Sotho and Afrikaans summaries / South Africa has a long and troubled educational history, from pre-colonial education to the fall of apartheid, and eventually the acquisition of equal education for all (Christie, 2006). Many changes took place during this transitional period in the democracy and liberation of the New South Africa by means of pupil-centred classrooms, Curriculum 2005 (Taylor, 1995) and Curriculum and Assessment Policy Statement (CAPS). Although numerous studies have been conducted internationally and in South Africa on underperforming in schools, the focus of this study is to ascertain the key elements of why learners underperform. The study’s aim is to determine the influence of a learner’s socio-economic situation on scholastic performance with references to nutrition, family structure, and parental support of learners in primary schools in Tshwane. In this full dissertation, the researcher found that most of the selected home environmental factors had no significant impact on the selected learners. It was, however, found (as many research already proved) that diet and sleep did have an influence on primary school learner academic performance. In presenting this argument, the theoretical framework, socio-constructivism learning theory, and Maslow’s hierarchy of needs, were used, as socio-constructivism states that although biological factors are a requirement for basic development to emerge, socio-cultural factors are crucial for basic natural processes to develop. Vygotsky’s socio constructivism theory indicates the uniqueness of the social environment and regards socio-cultural background as the primary and determining factor in the development of higher forms of human mental activity such as voluntary attention, intentional memory, logical thought, planning, and problem solving. In conjunction with Vygotsky, Maslow’s hierarchy of needs sets the foundation for this study as it states that in order for a being to move to the next level, the lower level of needs, need to be satisfied first. The objectives of the study were: - to determine what the impact of selected home environment factors on primary school learners’ academic performance is. To determine the relationship between poverty, family structure, and scholastic performance; to determine the influence of the type of dwelling on scholastic performance; to determine the influence nutrition have on a learners’ scholastic performance; and to determine the influence sleep deprivation has on learners’ academic performance. The study used a quantitative approach, and the method included questionnaires that learners in Grade 5, Grade 6, and Grade 7 of the selected school completed anonymously. The study revealed that poverty, family structure, and dwelling type did not have a significant impact on the learners of the selected school. The study did however reveal and confirmed what various other researchers have already found that sleep and nutrition did have an influence on academic performance. It is recommended that specific guidelines should be provided to parents about economical lunchbox ideas. Parents should be supplied with lists of foods best to pack in lunchboxes and food that is not allowed. Schools should further monitor the food provided at tuck shops, as the food provided should be nutritious as well as sustain learners’ energy. Food high in saturated fats and sugar should not be allowed at school tuck shops. Children should also be educated about nutrition and better or alternative choices they can make. Lunches that are supplied as part of the school nutrition program should be monitored to ensure that it is nutritious, low in sodium, and that a variety of fruit and vegetables are included in the meal. Studies have concluded that children should sleep on average nine hours per night. Unfortunately, due to increase in academic pressure and work load, more learners go to bed later. It is therefore recommended that schools adhere to guidelines on the amount of homework given to learners daily. It is further recommended that parents should ensure that their children have a set routine regarding sleep patterns. The use of electronic equipment, such as television, computers, and cellular phones prior to sleeping time should be limited as it affects sleep. Surprisingly, this study has also revealed that some of the data supplied to the school by the parents or guardians and the data that was obtained from the learners did not correlate. It is therefore recommended that schools should be more scrupulous with learner performance data as it could be a possible indicator of household problems or the quality of education. If it is found that the decline is due to quality of education, the school management team should act immediately to assist the necessary educators with the necessary skills to enable better quality of education. A pro-active plan of action should be put in place by the school for those learners whose marks decreased. An educator could talk to the learner and the parents to try and determine the possible causes for the decrease in marks. Remedial classes or remedial exercises should be given to the learners to assist in the areas of need. In addition, if it is determined that the cause is due to home environment factors then necessary assistance should be provided either by the school or other entities. / Afrika Borwa e na le histori ya thuto ye telele gape ya mathata, go tloga go thuto ya pele ga bokoloni go ya go go fedišwa ga kgatelelo le go hwetša mafelelong thuto ya go lekana go bohle (Christie, 2006).

Baie veranderinge het gedurende hierdie oorgangsperiode in die demokrasie en bevryding van die Nuwe Suid-Afrika plaasgevind deur middel van leerdergesentreerde klaskamers, Kurrikulum 2005 (Taylor, 1995) en die Kurrikulum- en Assesseringsbeleidsverklaring (KABV). Hoewel talle studies oor onderprestasie in skole internasionaal en in Suid-Afrika uitgevoer is, is die fokus van hierdie studie om die kernfaktore vas te stel wat tot onderprestasie van leerders lei. Die studie het ten doel om die invloed van ’n leerder se sosioëkonomiese situasie op skolastiese prestasie te bepaal met verwysing na voeding, gesinstruktuur en ouerondersteuning van leerders in primêre skole in Tshwane. In hierdie volledige proefskrif het die navorser bevind dat die meeste geselekteerde tuisomgewingfaktore geen beduidende uitwerking op die geselekteerde leerders gehad het nie. Daar is egter bevind (soos deur baie navorsers bewys is) dat dieet en slaap wel ʼn invloed op primêreskoolleerders se akademiese prestasie gehad het. In die aanbieding van hierdie argument is die teoretiese raamwerk, sosiaal-konstruktivistiese leerteorie en Maslow se behoeftehiërargie gebruik. Sosiaalkonstruktivisme bepaal dat, hoewel biologiese faktore ’n vereiste is sodat basiese ontwikkeling kan plaasvind, sosiaalkulturele faktore deurslaggewend vir die ontwikkeling van basiese natuurlike prosesse is. Vygotsky se teorie oor sosiaalkonstruktivisme dui op die uniekheid van die sosiale omgewing en beskou die sosiaalkulturele agtergrond as die primêre en bepalende faktor in die ontwikkeling van hoër vorms van menslike verstandelike aktiwiteit, soos vrywillige aandag, intensionele geheue, logiese denke, beplanning en probleemoplossing. Tesame met Vygotsky, maak Maslow se behoeftehiërargie die grondslag van hierdie studie uit, aangesien dit bepaal dat, ten einde na die volgende vlak te beweeg, ’n mens se laer vlak van behoeftes eers bevredig moet word. Die doelwitte van die studie was om die volgende te bepaal: watter uitwerking geselekteerde tuisomgewingfaktore op primêreskoolleerders se akademiese prestasie het; die verhouding tussen armoede, gesinstruktuur en skolastiese prestasie; die invloed van die tipe woning op skolastiese prestasie; die invloed wat voeding op ’n leerder se skolastiese prestasie het; en die invloed wat slaapontneming op ’n leerder se akademiese prestasie het. Die studie het ’n kwantitatiewe benadering gebruik, en die metode het vraelyste ingesluit wat leerders in Graad 5, Graad 6 en Graad 7 van die geselekteerde skool anoniem voltooi het. Die studie het aan die lig gebring dat armoede, gesinstruktuur en tipe woning nie ’n beduidende uitwerking op die leerders van die geselekteerde skool gehad het nie. Die studie het egter wel aan die lig gebring en bevestig wat verskeie ander navorsers reeds bevind het: dat slaap en voeding ʼn invloed op akademiese prestasie het. Daar word aanbeveel dat spesifieke riglyne oor ekonomiese kosblik-idees aan ouers verskaf moet word. Ouers behoort voorsien te word van lyste van die beste kossoorte om in kosblikke te pak, en kossoorte wat nie toegelaat word nie. Skole behoort voorts die kos te monitor wat by snoepwinkels te koop aangebied word, aangesien sodanige kos voedsaam moet wees en leerders se energie moet volhou. Kos wat ryk aan versadigde vette en suiker is, behoort nie by skoolsnoepwinkels toegelaat te word nie. Daarbenewens behoort kinders opgevoed te word oor voeding en beter of alternatiewe keuses wat hulle kan maak. Middagetes wat as deel van die skoolvoedingsprogram voorsien word, moet gemonitor word om te verseker dat hulle voedsaam en laag in sout is, en dat ’n verskeidenheid vrugte en groente by die maaltyd ingesluit word. Studies het tot die slotsom gekom dat kinders gemiddeld nege uur per nag behoort te slaap. Ongelukkig, weens ʼn toename in akademiese druk en werklading, gaan al hoe meer leerders later slaap. Daar word dus aanbeveel dat skole riglyne nakom rakende die hoeveelheid huiswerk wat daagliks aan leerders gegee word. Daar word verder aanbeveel dat ouers moet verseker dat hul kinders ’n vaste slaaproetine het. Die gebruik van elektroniese toerusting, soos televisie, rekenaars en selfone voor slaaptyd, behoort beperk te word omdat dit slaap beïnvloed. Dit is verrassend dat die studie ook aan die lig gebring het dat sommige van die data wat deur die ouers of voogde aan die skool verskaf is en die data wat van die leerders bekom is, nie ooreengestem het nie. Daar word dus aanbeveel dat skole meer nougeset met leerderprestasiedata moet omgaan, aangesien dit ’n moontlike aanwyser van huishoudelike probleme of die gehalte van onderwys kan wees. Indien daar bevind word dat die afname as gevolg van die gehalte van onderwys is, moet die skoolbestuurspan onmiddellik optree om opvoeders te help om die nodige vaardighede te verwerf om ’n beter gehalte onderwys moontlik te maak. Die skool behoort ’n proaktiewe plan van aksie in werking te stel vir daardie leerders wie se punte gedaal het. ʼn Opvoeder kan met die leerder en die ouers gesels en probeer vasstel wat die moontlike oorsake vir die daling in punte is. Remediërende klasse of remediërende oefeninge behoort aan die leerders gegee te word om met die behoefteareas te help. Daarbenewens, indien vasgestel word dat die oorsaak tuisomgewingfaktore is, behoort die nodige bystand gegee te word, hetsy deur die skool of ander entiteite. / Educational Studies / M. Ed.

Although the White Paper on Families (2013) stipulates that family resilience should be strengthened in family preservation services, no guidelines exist for social workers in the South African context to do so. A need for practice guidelines for social workers in rendering services to families to strengthen family resilience was identified. The following central research question was formulated: How and by doing what, can social workers foster and sustain family resilience? The Intervention Design and Development (IDD) model of Rothman and Thomas (1994) was adapted for the study which included qualitative research to explore and describe the understanding, experiences and suggestions of social workers on family resilience for informing the family resilience intervention guidelines. Data was collected through focus- group and face-to-face semi-structured interviews with social workers employed by the Department of Social Development, and the NGOs from Gauteng, North West and Limpopo province. Tesch’s steps (cited in Creswell 2009:186) were used to analyse the data systematically and data was verified by Guba’s model (cited in Krefting 1991:214–222). Implementing steps 1–5 of phase 1, steps 1–3 of phase 2, step 2 of phase 3 and steps 1–3 of phase 4 of the IDD model, “Practice Guidelines for Social Workers to foster and sustain Family Resilience” (“The Guidelines”) were developed by translating the family resilience theory into practice to guide social workers to be able to develop and implement a family resilience intervention. The content of “The Guidelines” include an introduction containing the social work service delivery principles, the theoretical approaches of service delivery to families and the legislative and policy framework for services to families that would underpin a family resilience intervention. Section 1 of “The Guidelines” was developed and structured around the understanding of the family resilience construct and the family resilience process model on how family resilience operates. Section 2 of “The Guidelines” is presented in a question and answer format. This section provides practical guidelines on how to identify the target group for family resilience interventions, the reciprocal relationship between individual resilience and family resilience, family resilience interventions following the social work intervention process (i.e. intake, developmental assessment, a family developmental plan, and intervention strategies in accordance with the basket of services for families and monitoring and evaluation), how to integrate the domains of family resilience into the family resilience intervention, the need for education of both the social worker and client family on family resilience, the multi-dimensional aspects of the family requiring a multi-disciplinary approach and the role that the safety of family members play when rendering a family resilience intervention. / Social Work / D.

The present study explored the interaction between paediatric asthma and family functioning, within the context of family systems theory. Eight families, each with an asthmatic child between the ages of 8 and 15, were included in this study. In each case, the parents were interviewed and completed a quantitative measure, the Family Assessment Device, The results indicated that each family has a unique way of functioning and of integrating the child's asthma into its lifestyle. Factors found to be involved in the mutual impact of paediatric asthma and family functioning were the size of the family, the severity of the child's condition, the ways in which the family copes with the stress of asthma, communication patterns between parents, compliance with family rules and boundaries, and the affective responsiveness and involvement of family members. / Psychology / M.A. (Psychology)

The present study explored the effect of the birth of a child with a cleft lip and palate on family functioning within the context of family systems theory. Five families, each with a child who was born with a cleft lip and palate, were included in the study. The five couples were all married and they were the biological parents of their children whose ages ranged from two months to five years. All five sets of parents were initially interviewed together and then had separate individual interviews where the Family Assessment Measure-III was administered. The results reflected each family's distinctive patterns of interaction and how they adapted to the birth of a child with an orofacial cleft. Factors found to affect family functioning included: External support systems, individual coping skills, family rules and boundaries, open communication and cohesion among family members. / Psychology / M.

Dans le cadre d'une étude transversale menée sur 202 patientes ménopausées et non ménopausées,les objectifs sont de démontrer l'existence d'un lien entre ménopause et altération de l'état de santé buccodentaire. D'évaluer l'action du THM sur la morbidité dentaire et «in fine» sur la mortalité dentaire.De préciser les liens entre santé bucco-dentaire et diverses pathologies générales et d'apprécier les liens entre psychisme et soma chez les femmes ménopausées. D'apprécier l'influence des biphosphonates sur l'état de santé parodontal.De placer l'étude des liens état bucco-dentaire- ménopause dans une optique sociétale et anthropologique.La ménopause a pour conséquence une altération du parodonte (p=0,003).Le THM a une action bénéfique sur le parodonte.L'effet biologique du diabète est drastique quant à la perte des organes dentaires (p=0,050).L'étude souligne l'influence «per se» d'un mauvais état bucco-dentaire pour la pathologie coronarienne (OR=1,214). De plus,évènements stressants,sècheresse buccale,pathologies ostéo articulaires,carence hormonale sont des facteurs diversement liés de la mortalité dentaire durant cette période. Par ailleurs, il est apparu que les femmes ayant été récemment traitées pour un cancer du sein développaient plus de caries dentaires (p=0,031 OR=2,161). L'étude met en évidence les effets des biphosphonates sur l'altération du parodonte (p=0,011) malgré la prise d'un THM (p=0,020).Un milieu socioculturel aisé contribueraient à la médicalisation du phénomène physiologique.Le fait de vivre seule influerait sur la perte des organes dentaires (p=0,035). Enfin,la pratique régulière d'un sport améliorerait l'état de santé orale (p=0,036). / In a cross-sectional study of 202 postmenopausal and premenopausal women,the objectives of this study are to demonstrate a link between menopause and altered state of oral health.To evaluate the action of HRT on dental disease and finally on the tooth mortality. To assess and clarify the relationship between oral health and various general diseases and links between psyche and soma in postmenopausal women.Also discussed was the influence of bisphosphonates on the state of periodontal health.Finally,it was decided to place the study links oral menopausal status in a social and anthropological perspective.It appears then that menopause results in an altered state of oral health,(p = 0.003).HRT has a beneficial effect on the periodontal disease.The biological effects of diabetes are related to dental mortality (p = 0.050). This study emphasize the influence "per se" a bad oral health status for coronary artery disease (OR = 1.214).In postmenopausal women, stressful events, dry mouth, joint and bone diseases, hormonal deficiency are factors variously related dental mortality during this period. Moreover, it was found that women who have recently been treated for breast cancer developed more dental caries (p = 0.031 OR = 2.161).The study related the effects of bisphosphonates on the alteration of periodontal (p = 0.011), despite taking HRT (p = 0.020).In addition,background socio-economic favored contribute to the medicalization of physiological phenomenon. The fact of living alone would affect the loss of dental organs (p = 0.035). Finally, the regular practice of a sport improve the state of oral health (p = 0.036).

The aim of this study was to develop, implement and evaluate a psycho-educational programme to enhance the efficacy of parents of adolescents. Thus, the research project can be identified as formative, evaluative research. To this end, an investigation was undertaken to determine how the efficacy of parents of adolescents could be enhanced through an understanding of: * the life phase of adolescence; * the life phase of parents of adolescents; * the role of parents of adolescents; * factors influencing the parenting of adolescents (e.g., generational effects and the influence of family structure on parenting); * the challenges facing adolescents and their parents which may hamper parenting efficacy; * factors which assist parents of adolescents to overcome challenges and improve their parenting efficacy; * parenting skills which foster parenting efficacy; and * the nature of a psycho-educational programme which could enhance the efficacy of parents of adolescents. A literature study provided the theoretical background to the development of the above mentioned programme. In the next phase of the study, a psycho-educational programme was developed based on the literature review, a study of similar programmes and a pilot study conducted with parents. The programme aimed at helping parents to become aware of their parenting practices, to encourage them to increase knowledge and understanding of themselves and of their adolescent children and to develop personal strategies and skills to cope with parenting challenges. The programme was implemented with a group of 21 parents of adolescents (five fathers and sixteen mothers) living in George, South Africa during sessions held once per week over a period of six weeks. Participants were divided into three groups: six single parents; eight parents of nuclear families; and seven parents from blended-extended families. Data was collected qualitatively during each meeting. In addition, focus groups were conducted at the end of the six weeks. The findings indicated that the programme enhanced the efficacy of the participating parents in supporting the development of their adolescent children. / Educational Studies / D.Ed (Psychology of Education)

From the moment children are born, they begin a lifetime journey of learning about themselves and their surroundings. With the establishment of the No Child Left Behind Act of 2001, it mandates that all children receive a high-quality education in a positive school climate. Regardless of the school the child attends or the neighborhood in which the child lives, proper and quality education and resources must be provided and made available in order for the child to be academically successful. The purpose of this ex post facto study was to investigate the relationship between the FCAT 2.0 mathematics scores of public middle school students in Miami-Dade County, Florida and the concentrations of a school’s racial and ethnic make-up (Whites, Blacks, and Hispanics), English for Speakers of other Languages (ESOL) population, socio-economic status (SES), and school climate. The research question of this study was: Is there a significant relationship between the FCAT 2.0 Mathematics scores and racial and ethnic concentration of public middle school students in Miami-Dade County when controlling SES, ESOL student population, and school climate for the 2010-2011 school year? The instruments used to collect the data were the FCAT 2.0 and Miami-Dade County Public Schools (M-DCPS) School Climate Survey. The study found that Economically Disadvantaged (SES) students socio-economic status had the strongest correlation with the FCAT 2.0 mathematics scores (r = -.830). The next strongest correlation was with the number of students who agreed that their school climate was positive and helped them learn (r = .741) and the third strongest correlation was a school percentage of White students (r = .668). The study concluded that the FCAT 2.0 mathematics scores of M-DCPS middle school students have a significant relationship with socio-economic status, school climate, and racial concentration.
