The experience and aftermath of chronic bullying on individuals' socio-emotional developmentDarney, Christine Kyle January 2009 (has links)
Bullying behaviour is fast becoming a common feature in schools around the world. It is a practice that provokes concern, as it infringes upon the child’s right to human dignity, privacy, freedom and security. The physical, emotional and educational consequences of bullying behaviour can never be underestimated (Oyaziwo, 2008). Limited research has been conducted in South Africa regarding the prevalence and possible long-term effects of chronic bullying at school. This study intended to explore and describe the prevalence of bullying behaviour among a sample of grade 8 learners and the prevalence of previous chronic bullying at school among a sample of young adults in the Nelson Mandela Metropole. In addition, the study aimed to explore and describe the relationship between chronic bullying at school and self-esteem and attachment styles. Finally, the contextual factors which may influence the outcomes of chronic bullying for victims were explored and described. The study was exploratory descriptive in nature and employed a mixed method research design. Participants were selected by means of non-probability sampling. The sample consisted of 225 grade 8 learners at a secondary school in the Nelson Mandela Metropole and 101 young adult participants who had completed their school education in the Nelson Mandela Metropole within the past sixteen years. Data on the demographics of the sample was gathered through the administration of a biographical questionnaire. Furthermore, the Olweus (1996) Bully/Victim Questionnaire was utilized in order to obtain information about the prevalence of bullying behaviours among the participants. James Battle’s (1981) Culture-Free Self-Esteem Inventories were used to measure the construct of self-esteem, and Bartholomew and Horowitz’ (1991) Relationship Questionnaire was employed in order to identify the participants’ current attachment styles. Individual semi-structured interviews were later conducted among a sub-set of young adult participants, who had experienced chronic bullying at school, in order to identify the contextual factors which may have influenced the xiii outcomes of their experiences of victimization. Descriptive and inferential statistics, including correlations and multivariate analysis of variance (ANOVA), were utilized in order to analyze the quantitative data. Key findings revealed that eighty-five percent of the grade 8 participants had been involved in bullying behaviours at school this year and ninety-one percent of the young adult participants had been involved in bullying behaviours during some stage of their school careers. No significant relationship was found to exist between bullying and self-esteem in the grade 8 sample. Self-esteem scores did however vary significantly among the victims, bully-victims and bystanders in the young adult sample. Correlational coefficients confirmed that there was a significant relationship between previous chronic bullying at school and the total self-esteem scores of participants in the young adult sample. Findings also showed that there was no significant relationship between bullying and attachment in either of the samples in this study. Finally, qualitative results revealed that a number of contextual factors influenced the outcomes of chronic bullying at school for the sub-set of young adult victims. These factors included: The nature, frequency and duration of the bullying behaviour, the victims’ social support at the time as well as the victims’ personal characteristics.

Strategic approach to psychotherapeutic intervention with male institutionalized white adolescents to control abscondingHoar, Robyn January 1988 (has links)
Bibliography: pages 92-98. / Using a systems theoretical orientation the objective of this study was to implement a strategic approach for psychotherapeutic intervention with six male institutionalized white adolescents at a local custodial school. It was hypothesized that a strategic approach would control absconding for the duration of the investigation. Surveys of the literature were undertaken to provide the background to psychotherapeutic intervention with adolescents in custodial institutions, strategic psychotherapy and absconding. Absconding was selected as the condition for evaluating the interventions because it was an unambiguous indicator of school-based recidivism, viz., the adolescent was either on the property or he was not. The study was structured as a design-and-demonstrate investigation. Audiotape recordings were made during the sessions. Transcriptions of characteristic procedures and sequences of the strategic approach to psychotherapeutic intervention were presented, inter alia, paradoxes, reframing, metaphors, rituals, the declaration of therapeutic impotence. Evaluation of the interventions was based on follow-up interviews with the subjects and a qualitative analysis of risk of absconding aver the course of the intervention process. At the end of the investigation there was some evidence which suggested that five out of the six subjects were not as committed to absconding as they had claimed to be at the beginning of the study. The design of the study did not allow for the conclusion that the strategic approach for controlling absconding was of greater merit than any other form of intervention or no intervention at all. It was noted, however, that twelve of the eighteen potential subjects for the study indicated that they would abscond as soon as the opportunity arose. Therefore it was recommended that the issue of absconding be given priority in therapy on the admission of each new pupil. Given a strategic approach to addressing the issue of absconding in therapy, attention was drawn to a major aim of this type of intervention, viz., to generate a sense of personal autonomy. Hence a further recommendation was that once a pupil had made a commitment not to abscond, his sense of autonomy would need to be supported by an expeditious transfer to one of the more open hostels.

Socio-emotional development in children of teenage mothersMahwai, Lerato January 2016 (has links)
Research Submitted in partial fulfillment for the degree MA in Psychology by Coursework and Research
Report
Wits School of Human & Community Development,
University of Witwatersrand, Johannesburg,
June, 2016 / Research has found that teenage mothers are less likely to develop a positive parent child relationship and to form an emotional bond with the child because they are not prepared to be parent as teenagers. Since there is high rate of teenage pregnancy in South Africa, this would mean that there is a vast amount of teenage mothers in the country. Therefore, it would be expected that, it would be a challenge for these teenage mothers to form an emotional bond with their children. Hence the purpose of the study is to look at the socio-emotional development of children born to teenage mothers in the South African context. This was done by first investigating whether there was a relationship between teenage childbearing and the child’s social-emotional development in middle and late childhood and to determine whether the socio-emotional development of children born to teenage mothers differs significantly with the children that are not born to non-teenage mothers. This study adopted a non-experimental Ex-Post-Facto correlational Design. A self-designed biographical information questionnaire was used to measure the demographics. To measure social-emotional development in children, an Emotional Quotient Inventory: The preliminary results of the research indicate that the type of mother was a statistically significant predictor of the child’s social and emotional development. Furthermore, that the socio-emotional development of children born of teenage mothers was different from the socio-emotional development of children born to non-teenage mothers, as the social and emotional development of children born to teenage mothers was higher than that of children born to non-teenage mothers. The conclusion can be drawn that teenage childbearing does not seem to negatively influence the social and emotional development of children born to teenage mothers

Coping behaviour of wives of relocated employeesdu Plessis, Karin 05 March 2015 (has links)
This quantitative-descriptive study explored the effect of
relocation cn wives, of employees of an Eastern Cape motor
manufacturing company, who were relocated during the
period July 1991 to November 1993. Specifically, it aimed
to identify the coping behaviour of two samples of such
wives, those of employees ./ho were relocated from overseas
(international group) and those who were relocated from
within South Africa (national group). A control group,
comprised of wives of employees who f had not relocated
within the last ten or more years, was utilised. The study
made use of three research tools: a structured interview
schedule compiled by the researcher, the Beck's (1981)
Depression Inventory and the Hudson's (1982) Index of
Marital Satisfaction.

The Baby Mat Project : similarities and differences between the experiences and perceptions of mothers and therapists.Nkosi, Nonhlanhla Shirley 22 July 2014 (has links)
The early relationship between mother and child is formative of a child’s later wellbeing. Disruptions in the mother-infant bond can result in insecure attachments. There therefore exist certain interventions which endeavour to avoid the development of insecure relationships and instead begin to develop more secure mother-infant bonds. Such interventions include the Ububele Baby Mat project run in Alexandra township, Johannesburg. As this intervention is still developing, the Ububele team requested that research be conducted on this intervention. This research aims to better understand the Ububele Baby Mat’s influence on those caregivers who access the Baby Mat service, and also to record the subjective experiences of the therapists who facilitate the mat service. The current research was therefore aimed at exploring the subjective experiences of both the mothers and therapists involved in the Baby Mat intervention and further to explore any similarities or differences between these two groups’ experiences. Data was obtained through semi-structured interviews with mothers who accessed the Baby Mat service and with both the therapists who facilitated the mother participants’ sessions. Thematic content analysis was used to analyses the data. The findings showed that in general mothers had a positive experience of the Baby Mat service and of the therapists on the mat. Another finding was that there were more similar experiences than different ones between mothers and therapists.

A Foucauldian discourse analysis of South African women's experience of involuntary childlessnessKantor, Barbara January 2006 (has links)
Magister Psychologiae - MPsych / As a consequence of positioning women within the dominant gender role of motherhood, the inability to have a child has exposed women, and more notably women in Africa, to extreme social consequences that often violate their human rights and lead to socio-economic disempowerment. The aim of this study was to consider prevailing discursive construction that position women within dominant ideologies that engender motherhood for women, and to explore how women make sense of and construct meaning regarding their experience when they desire but are not able to have a child. / South Africa

Physiological demands of the Absa Cape Epic mountain bike race and predictors of performanceGreeff, Marli 12 1900 (has links)
Thesis (MScSportSc)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The purpose of this qualitative-quantitative study was to describe the exercise intensity and
predictors of performance of a multi-stage mountain bike (MTB) race (2014 Absa Cape Epic)
lasting 8 days. Twenty-three amateur mountain bikers (age 39 ± 9 years, height 178.8 ± 8.2
cm, body mass 74.7 ± 9.1 kg, VO2max 54 ± 7 ml.kg-1.min-1) who completed the 2014 Absa
Cape Epic were involved in the study. The participants were divided into two groups
according to their MTB experience. The experienced group included participants who
previously completed more than three 3-day multi-stage MTB events and the novices group
included those who has completed less than 3-day multi-stage MTB events.
Prior to the event the participants completed a maximal aerobic cycling test and a simulated
40 km time trial (TT). The maximal aerobic test was used to determine 3 work intensity
zones based on heart rate (HR) corresponding to blood lactate thresholds (LT: increase in
blood lactate concentration of 1 mmol.l-1 above baseline values and the onset of blood
lactate accumulation (OBLA), a fixed blood lactate concentration of 4 mmol.l-1). There were
no statistically significant differences in the physical, physiological and performance
variables measured in the laboratory between the two groups. The exercise intensity during the Cape Epic was measured using telemetric HR monitoring
sets. RPE values were noted after each stage of the race. The mean HR was 88.1 ± 5.3%
(experienced) and 84.2 ± 11.0% (novices) of maximal HR during the race or 88.9 ± 3.5%
(experienced) and 85.9 ± 10.6 (novices) of laboratory determined maximum HR. More time
was spent in the “low” HR zone (43.1 % vs 58.5 %, respectively), while only a small amount
of time was spent in the “hard” HR zone (7.4% and 6.1%, respectively). The experienced
group spent statistically significantly more time in the “moderate” HR zone compared to the
novices group (49.5 % vs. 35.4 %). The experienced group performed significantly better
during the event compared to the novices group in both the total event time (P = 0.004) and
the general classification (P = 0.01).
Relative and absolute power output (PO) at OBLA (P = 0.01 and 0.02, respectively) were
statistically significant predictors of total event time, while relative peak power output was a
significant predictor of general classification for the event (P = 0.02) . The total TT time was
a significant predictor of average event HR (P = 0.03). This study showed that this MTB stage race is physiologically very demanding and requires
cyclists to have excellent endurance capacity, as well as strength and power. The
parameters from the maximal aerobic capacity test correlated better with outdoor
performance than parameters from the simulated 40 km TT. Therefore the standard
maximal aerobic capacity test are sufficient for testing mountain bikers and sport scientists
can continue using this test to prescribe exercise intensity zones for training and events. / AFRIKAANSE OPSOMMING: Die doel van hierdie kwalitatiewe-kwantitatiewe studie was om die oefeningsintensiteit en
voorspellers van prestasie tydens ‘n multi-dag bergfiets kompetisie (Absa Cape Epic) van 8
dae lank te bepaal. Drie-en-twintig bergfietsryers (ouderdom 39 ± 9 jaar, lengte 178.8 ± 8.2
cm, liggaamsmassa 74.7 ± 9.1 kg, VO2maks 54 ± 7 ml.kg-1.min-1) wat die 2014 Absa Cape
Epic voltooi het, het aan die studie deelgeneem. Die deelnemers is in twee groepe verdeel
volgens hulle ervaring in multi-dag bergfiets kompetisies. Die ervare groep was al die
deelnemers wat meer as drie 3-dae multi-dag bergfiets kompetisies voltooi het. Die onervare
groep was al die deelnemers wat minder as drie 3-dag multi-dag bergfiets kompetisies
voltooi het.
Voor die kompetisie het al die deelnemers ‘n maksimale aërobiese toets en ‘n gesimuleerde
40 km tydtoets in die laboratorium voltooi. Die maksimale aërobiese toets is gebruik om drie
werk intensiteit sones volgens die hartspoed te bepaal, naamlik die hartspoed by die
laktaatdraaipunt(‘n toename in bloed [laktaat] van 1 mmol.l-1 bo die basislynwaardes) en die
hartspoed by die aanvang van bloedlaktaat akkummulasie (‘n vaste bloed [laktaat] waarde
van 4 mmol.l-1). Daar was geen statisties betekenisvolle verskille in die fisiese, fisiologiese
en prestasie veranderlikes tussen die twee groepe nie.
Die oefeningsintensiteit tydens die Cape Epic was gemeet deur gebruik te maak van
hartspoedmonitors. Die RPE waardes was aan die einde van elke skof genoteer. Die
gemiddelde hartspoed was 88.1 ± 5.3 % (ervare) en 84.2 ± 11.0 % (onervare) van
maksimale kompetisie hartspoed, of 88.9 ± 3.5 % (ervare) en 85.9 ± 10.6 % (onervare) van
die maksimale hartspoed soos in die laboratorium gemeet. Die fietsryers het meer tyd spandeer in die “lae” hartspoed sone (43.1 % vs 58.5 %,
onderskeidelik), in vergelyking met die “moeilike” hartspoed sone (7.4 % vs 6.1 %,
onderskeidelik). Die ervare groep het statisties betekenisvol meer tyd in die “matige”
hartspoed sone spandeer (49.5 % vs. 35.4 %) in vergelyking met die onervere groep. Die
ervare groep het beter presteer tydens die kompetisie vir beide totale kompetisie tyd (P =
0.004) en algehele klassifikasie (P = 0.01).
Relatiewe en absolute krag by aanvang van bloed laktaat akkumulasie was statisties
betekenisvolle voorspellers van totale kompetisie tyd (P = 0.01 en 0.02, onderskeidelik),
terwyl maksimale krag ‘n statisties betekenisvolle voorspeller was van algehele klassifikasie
in die kompetisie (P = 0.02). Die totale tydtoets tyd was ‘n statisties betekenisvolle
voorspeller van gemiddelde hartspoed tydens die kompetisie. Die studie het gewys dat hierdie multi-dag bergfiets kompetisie fisiologies baie uitdagend is
en dat fietsryers uistekende uithouvermoë kapasiteit, sowel as krag en plofkrag moet besit.
Die veranderlikes van die maksimale aërobiese toets het beter met prestasie in die veld
gekorreleer as die veranderlikes van die gesimuleerde 40 km tydtoets. Daar word dus
afgelei dat die standaard maksimale aërobiese toets voldoende is vir die toetsing van
bergfietsryers en sportwetenskaplikes kan aanhou om hierdie toets te gebruik om
oefeningsintensiteit sones voor te skryf vir oefensessies en kompetisies.

Psychological experiences of placement in correctional facilities within the Western Cape Province of South Africa : an exploratory study of incarcerated youthSlabber, Hester Jacoba 04 1900 (has links)
Thesis (MA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Focusing on the social-psychological level, where the focus is on negative relationships with others, Agnew’s General Strain Theory (GST) is internationally one of the most widely employed criminological theories explaining the onset and manifestation of youth offending. GST contends that youth are pressured into criminal behaviour by the negative affective states generated by negative relationships, which are characteristically defined as either aversive or not from the perspective of the youth; where especially anger motivates the youth to engage in maladaptive behaviour, resulting in maladaptive coping.
Applying data from 81 incarcerated youth from three correctional centres located in the Western Cape province of South Africa, the study focussed on the criminogenic effects of four variables to explain youth offending under the auspices of GST: self-control (using the Self-Control Schedule [SCS]), coping (using the Coping Strategy Indicator [CSI]), perceived social support (using the Social Support Appraisal scale [SSA]) and anger (using the State-Trait Anger Scale [STAS]). Results displayed significant positive correlations between self-control and the use of problem-solving coping, followed by significant positive correlations between self-control and perceived social support from family members, significant positive correlations between anger and the use of avoidant coping, as well as significant positive correlations between self-control and the use of avoidant coping. The results furthermore displayed significant negative correlations between anger and self-control, followed by significant negative correlations between anger and perceived social support from family members and friends respectively. In addition, the problem-solving coping strategy emerged as a significant positive predictor of self-control, whereas the avoidant coping strategy emerged as a significant positive predictor of anger. Anger, however, emerged as a significant negative predictor of self-control, where the social support-seeking coping strategy emerged as a significant negative predictor of perceived social support from family members.
Support for the possible application of Agnew’s GST to the context of South Africa was found and inferences made for the implications for intervention, where it was suggested that psychologists and social workers working with the rehabilitation of youth offenders consider the application of multisystem therapy (MST) with youth offenders, as MST aims to influence maladaptive behaviour by changing key aspects of the youth’s social context in ways that promote pro-social behaviour rather than maladaptive behaviour.
The study concluded with a recommendation for further longitudinal research to gain a better understanding of the strain-crime relationship that influence youth to engage in maladaptive behaviour, as is mentioned in GST literature. / AFRIKAANSE OPSOMMING: Met fokus op die sosiaal-sielkundige vlak, veral op negatiewe verhoudings met ander, word Agnew se Algemene Spanningsteorie (AST) internasionaal as een van die mees gebruikte kriminologiese teorieë beskou, wat die ontstaan en die verskyning van jeugmisdaad verduidelik. AST beweer dat jeug druk ervaar om deel te neem aan kriminele gedrag as gevolg van die negatiewe affektiewe toestande wat deur negatiewe verhoudings bepaal word, wat kenmerkend gedefinieer word as óf negatief of nie uit die perspektief van die jeug; waar veral woede die jeug motiveer om betrokke te raak by wanaangepaste gedrag, wat lei tot wanaangepaste omgaan.
Deur die toepassing van data van 81 jeuggevangenes van drie korrektiewe sentrums geleë in die Wes-Kaap provinsie van Suid-Afrika, het die studie gefokus op die kriminogeniese gevolge van vier veranderlikes wat jeugmisdaad onder leiding van AST verduidelik: selfbeheer (met behulp van die Selfbeheer Skedule [SCS]), omgaan (met behulp van die Omgaanstrategieskaal [CSI]), waargenome sosiale ondersteuning (met behulp van die Sosiale Ondersteuning Erkenningskaal [SSA]) en woede (met behulp van die State-Trait Woedeskaal [STAS]). Resultate vertoon beduidende positiewe korrelasie tussen selfbeheer en die gebruik van probleemoplossingsomgaan, gevolg deur 'n beduidende positiewe korrelasie tussen selfbeheer en vermeende sosiale ondersteuning van familielede, 'n beduidende positiewe korrelasie tussen woede en die gebruik van vermydingsomgaan, sowel as 'n beduidende positiewe korrelasie tussen selfbeheer en die gebruik van vermydingsomgaan. Die resultate vertoon verder 'n beduidende negatiewe korrelasie tussen woede en selfbeheer, gevolg deur 'n beduidende negatiewe korrelasie tussen woede en vermeende sosiale ondersteuning van familielede en vriende onderskeidelik, sowel as tussen waargenome sosiale ondersteuning van familielede en die gebruik van sosiale ondersteuningsoekende omgaan. Verder, met die regressie-ontleding het probleemoplossingsomgaan na vore gekom as 'n beduidende positiewe voorspeller van selfbeheer, terwyl vermydingsomgaan na vore gekom as 'n beduidende positiewe voorspeller van woede. Woede het egter na vore gekom as 'n beduidende negatiewe voorspeller van selfbeheer, waar die sosiale ondersteuningsomgaan na vore gekom het as 'n beduidende negatiewe voorspeller van waargenome sosiale ondersteuning van familielede.
Ondersteuning vir die moontlike toepassing van Agnew se AST in die konteks van Suid-Afrika was gevind en afleidings gemaak vir die implikasies vir ingryping, waar dit voorgestel word dat sielkundiges of sosiale werkers, wat met die rehabilitasie van jeugmisdadigers werk, gebruik maak van multi-sisteem terapie (MST), aangesien MST die doel het om wanaangepaste gedrag te beïnvloed deur die verandering van die belangrikste aspekte van die jeug se sosiale konteks op maniere wat pro-sosiale gedrag, eerder as wanaangepaste gedrag, bevorder. Die studie het afgesluit met die voorstel dat verdere longitudinale navorsing aanbeveel word om 'n beter begrip van die spanning-misdaad verhouding te kry wat 'n invloed speel op jeug betrokkenheid by wanaangepaste gedrag, soos genoem in AST literatuur.
