The prevalence of obesity is a growing problem for children and adolescents worldwide (Schwellnus & Derman, 2003:12; Verster, 2001:15; Cameron, 1999:75). Obesity contributes to primary and secondary health risks such as coronary heart disease and diabetes (Kalk, 2001:576). Obesity is inheritable as well as the health disorders associated with the type of obesity (Kalk, 2001:576; Dietz, 1995:157; Garfinkel & Cosina, 1990:511; Bouchard et a/., 1985:64). A possible cause for the increase of obesity is inactivity, and this generates numerous health problems for children and adolescents (Du Toit & Van der Merwe, 2003:49; Verster, 2001:15; Kalk,2001:576; Steinbeck, 2000:28; Cameron, 1999:75; Reilley et a/., 1999:217). Research has shown that regular exercise can lower the risk of obesity and have many health benefits in general (Deheeger et a/., 1997:375).Consequently the participation of physical activity is important for everyone not only for the obese individual (Van Mil et a/., 1999:842). Physical activity has physical as well as psychological benefits such as positive development in self-concept (Walters & Martin, 2000:51). A positive self-concept during adolescence can have an influence on mental and physical health, and the development of a positive self-concept is critical during the adolescent period (Park, 2003:42). Research also indicates that a strong self-concept can lead to an increase in participation physical activity (Park, 2003:47). Physical activity can also be a social opportunity during which self-concept and self-worth can develop (Marsh, 1997:28). The objective of this study firstly was to determine the influence of a 16-week physical activity intervention program on body composition and self-concept of black South African adolescents. The second objective was to determine the incidence of obesity among these adolescents. The third objective was to determine the influence of body composition on self-concept after participation in a 16-week physical activity intervention program. A total of 95 black adolescents (ages 13 to 18) were recruited to participate in the PLAY study (Physical Activity for the Youth). A control group of 24 adolescents did not participate in any exercise, where an experimental group of 71 adolescents did indeed participate in a 16-week physical activity intervention program. Anthropometric measurements and a comprehensive body composition were taken, using skin folds, BMl and the Bod Pod. The subjects completed a self-concept questionnaire (PASWIN2004 computer program). The findings in this study seems to indicate that there was a positive relationship, between physical activity and BMI as well as Bod Pod changes, after a 16-week activity intervention program in the experimental boys group. No further correlations were traced in the other groups. Among all the adolescents (experimental and control groups), were 80.85% overweight, of which 40.42% were classified as obese. This shows that the majority of this group of adolescents were overweight. No significant changes were found in body composition. The girls showed a slight increase in BMI as well as body fat percentage and a decrease in self-concept. This indicates that an increase in body fat can lead to a lower self-concept. / Thesis (M.Sc.

This study is a subdivision of an inter-university research project to investigate the psychological resilience of children in the late middle childhood years. The title of the umbrella project is Psychological resilience in children in the South African context. The aim of this study was to determine whether a relationship exists between social support and self-concept, as well as to establish whether gender differences occur with regard to the experience of social support and the evaluation of self-concept. Schools in different regions were identified in order to make the sample as large and the study as representative as possible of the different provinces, racial and language groups in South Africa. The children in the samples were randomly selected from class lists. The complete test battery was subsequently administered to these children. For the purpose of this study only the Piers-Harris Children's Self-concept Scale, the Social Support Appraisal Scale and the Biographical Questionnaire were used. Due to practical problems, the final figures of the samples varied between 549 and 918 participants. The processing of the data was done by the Statistical Consultation Service of the North West University Potchefstroom Campus. The Pearson Correlation Coefficient was used as an effect size to determine the relationship between social support and self-concept. T-tests and Cohen's effect sizes were used to determine whether gender differences occur with regard to social support and self-concept. The statistical processing of the results revealed that a positive correlation exists between social support and self-concept. These results are corresponding with the literature (Collins, 2000; Kirkcaldy, Shephard & Stiefen, 2002; Malecki 8 Demaray, 2002; Marjoribanks & Mboya, 2001; Van Tassel-Baska & Olszewski-Kubilius, 1994). Further, the results showed that no gender differences that were both statistically significant and practically meaningful occurred with regards to social support and self-concept. These results were repeatedly inconsistent with the literature (Bee, 1992; Dubow & Ullman, 1989; Harris, Rosenthal & Snodgrass, 1986; Hirsch & Rapkin, 1987; Piers, 1984; Werner & Smith, 1982). Finally, the last section of this investigation provides recommendations for further studies in this area, as well as practical suggestions for the implementation of the findings. / Thesis (M.A. (Clinical Psychology))--North-West University, Potchefstroom Campus, 2005

Problems that face teachers, especially those in secondary schools, are discussed. How they have developed over the years to what is now considered to be a crisis level, the increase in absenteeism and illness of the teaching force are also reviewed. A review of existing material explains the nature of stress. The psychobiological aspects are reviewed paying particular attention to the many coping mechanisms that the person will employ and explains how perceptions of situations can play a vital role. Factors that create stress for the teacher are discussed and categorised into familiar sections including pupils, working conditions, working in an organisation, the effects of management, the self concept and role conflict. Selection, training, assessment, pay and promotion are dealt with together in an additional category. Results from a Questionnaire completed by teachers from four local education authorities provides additional material to be considered and reinforces many of the previous claims and observations. After the findings are discussed, conclusions and recommendations are made for the improvement of morale and the reduction of stress in the teaching profession. Many of the conclusions made are linked closely to the self concept of the teacher. This self concept appears to be the focal point at which the problems besetting the teacher meet and are dealt with in either a positive or negative manner. Many of the recommendations made have the effect on the self concept of the teacher as a prominent feature. The stress provoking situations experienced by teachers seem to be reaching unacceptable levels. The physical and mental welfare of teachers is called upon to be monitored in order to reduce the harmful effects that poorly motivated teachers may have on pupils and in order to reduce the physical and mental difficulties apparently being suffered by the teaching profession.

Although a modest body of literature has emerged to investigate the experiences of youth with Autism Spectrum Disorder (ASD), there is a need to better understand their experiences to guide developmentally appropriate interventions and supports. This exploratory mixed-methods project included two studies aimed at gathering information about the self-perceptions and lived experiences of adolescents with ASD. In study 1, 27 adolescents (ages 13-18) completed measures to examine their self-concept and self-perceived competence, self-awareness of ASD characteristics and behaviours, and the types of behavioural attributions and stigmatizing beliefs they ascribe to their problematic behaviours. Two comparison groups (adolescents with Attention Deficit Hyperactivity Disorder and typically developing adolescents) were used for self-concept and behavioural attribution comparisons. Study 2 comprised a smaller sub-set of 13 participants who participated in interviews designed to capture how ASD is perceived and experienced by those living with this disorder. Study 1 results suggested that adolescents with ASD have some awareness of the social, behavioural and adaptive challenges associated with their diagnosis and, as a group, hold some self-perceptions of competence and behavioural attributions that are different from those of adolescents without ASD. In Study 2, interviews were analyzed thematically to capture how adolescents talk about their diagnosis and psychosocial experiences, and how this may impact their self-concept and self-image. Four major categories emerged: (1) self-awareness and understanding of ASD; (2) psychosocial stress; (3) social-ecological factors; and (4) sources of support. Together, these results provide insights about how they perceive themselves and their diagnosis and some of the individual, family, and school factors related to their self-perceptions and self-awareness. Results from both studies converge to provide support for a systems approach to understanding the interactions between adolescents, families, peers, school, community, and greater society when undertaking individual assessments of needs and treatment planning for ASD. Findings from the studies are discussed with respect to the positive and negative effects of awareness and knowledge about one’s diagnosis on self-perceptions and psychological adaptation. This research has important implications for clinical and educational interventions that address the unique needs and strengths of adolescents with ASD to promote positive developmental outcomes.

Social competence and positive self-concept are essential to future adaptive outcomes and overall well-being; but children and adolescents with learning disabilities (LD) frequently struggle in these domains. This dissertation examined changes in the social competence and self-concept of campers with learning disabilities (LD), within a specialized summer camp, with particular focus on friendship development. The dissertation is presented in two manuscripts, which will be submitted for publication. The objective of the first manuscript was to examine changes in campers’ social skills, social acceptance, self-worth, and self-esteem, within the context of summer camp, as reported by parents and campers. Parental reports indicated small gains in social skills, social acceptance, and self-worth from the beginning to the end of camp; with gains in social acceptance and self-worth maintained four to five months later. Campers did not report changes in any domains. Parents and campers reported declines in camper self-esteem at follow-up. In general, campers with LD+ADHD exhibited smaller gains in social competence and self-concept, than those with LD. Results are discussed in relation to theoretical frameworks and existing camp and LD research. The objective of the second manuscript was to investigate campers’ friendship development, within the summer camp context. Many campers reported having high-quality, reciprocal friendships at the beginning of camp. Campers reported more reciprocal friendships after camp, but these were not maintained at follow-up. Campers also reported having a best camp friend by the end of camp, and this relationship was maintained at follow-up. In terms of friendship quality, campers reported increased closeness by the end of camp and conflict ratings were low, overall. This study examined factors predicting changes in social competence. High-quality, reciprocal friendships predicted changes in campers’ social acceptance, according to parents. Similarly, reciprocal friendships predicted changes in camper reported social acceptance. These results highlight the inter-connections between friendship and aspects of social competence. Camp attendance was found to be a relevant factor in friendship development and quality. The concluding chapter discusses social competence, friendship, and self-concept outcomes for campers with LD within the context of a specialized summer camp. The implications of the findings for present theory and clinical practice are discussed, including specific recommendations for this camp’s structure and program evaluation procedures.

Self-concept is a very complex structure that includes feelings and beliefs, which people have about them in relations to other people and objects. Many marketers and researchers found that expression of self has a great influence on customer’s buying behavior and defines her attitudes towards products and services that correspond to her self-concept. This study, which is based on quantitative research with deductive approach, examines a self-concept of women in advertising across cultures. One hundred and sixty respondents from Russia and Sweden in the age from eighteen to thirty have been asked to identify the ideal eye color, hair color, hair length and make-up for a woman in order to look beautiful. Besides that, congruence between advertising images of female beauty and consumer's perception of ideal self in terms of wanting to look like a specific model was tested. After analysis of empirical results, some differences, as well as similarities between two countries have been found. Since the issues of advertising standardization still are in the focus of many studies, findings of this study is another argument in favor of adaptation international advertising campaigns to the specific requirements of local markets in different countries.

The overall goal of this study was to develop a comprehensive model of moral development to explicate the complexities of everyday morality. Based on a holistic and complementary perspective, the model relates the constructs of “worldview” and “self-view” to represent the influence of cultural individualism-collectivism and personality on moral development. It posits that worldview shapes self-view and moral inclusiveness [what is included in one’s moral consideration (Carter, 1980)] and then worldview, self-view, and moral inclusiveness jointly influence moral orientation (the main hypothesis). Interacting with situational factors, moral orientation would further influence moral judgment and behavior, thus connecting habitual morality with reflective morality. The specific objectives were: (a) to examine the relational structures among worldview, self-view, moral inclusiveness, and moral orientation; and (b) to construct a moral orientation index that measures various moral orientations, including egocentric, family, care, norm, justice, biocentric, and religious orientations, reflecting the corresponding worldviews, self-views, and levels of moral inclusiveness. Moral inclusiveness was operationalized as relationship closeness to different social groups at expanding levels of moral inclusiveness: (1) self only, (2) family, (3) peers, (4) society, (5) humanity, (6) nature, and (7) God. Survey data were gathered from 640 Grades 8-12 students and 472 adults. Structural equation models (SEM) were developed using the student data while making some comparative references to the adult data. Results of SEMs generally supported the main hypothesis. For example, individuals scoring higher on vertical individualism, social Darwinism, and independent self scored higher on egocentric orientation; individuals scoring higher on vertical collectivism and closeness to family scored higher on family orientation; and individuals scoring higher on horizontal collectivism and interdependent self scored higher on care orientation, at Levels 1, 2, and 3 respectively. Individuals scoring higher on collectivism, horizontal worldview, and moral self scored higher on justice orientation, but individuals scoring higher on closeness to nation scored lower on justice orientation at Level 5. The primacy of worldview, particularly collectivism, over self-view and moral inclusiveness in moral orientation development has implications for education. Exploring the roots of habitual morality, this study advances theory by integrating different schools of moral psychology with cultural psychology.

This study aimed to identify motivational factors affecting self-regulated learning (SRL) in the context of second language acquisition. Rather than investigating learners’ overall disposition toward their learning, it focused on a particular task, the learning of kanji in Japanese, in order to provide a clearer picture of the complex relationship between motivation and SRL. Using quantitative methods, the underlying structure of motivation and SRL was explored and the relationships among the extracted factors were examined. On the basis of a self-administered questionnaire specifically developed for this study, the data were obtained from 381 tertiary students studying Japanese at one of the seven cooperating institutions in New Zealand. Principal components analyses identified three motivational orientations (intrinsic, instrumental mastery, and performance orientation), four sources of motivation (self-efficacy, self-concept, extrinsic value, and intrinsic value), and four types of self-regulation (behavioural, environmental, cognitive, and metacognitive regulation) involved in kanji learning. The results of correlational analyses revealed a number of significant relationships suggesting the interdependence of the identified constructs. However, instrumental mastery, performance orientation, and extrinsic value did not predict students’ use of SRL. Further investigation of individual and situational factors indicated that learning opportunities outside the classroom possibly confounded the significant relationships between these non-predictors and SRL. On the other hand, intrinsic orientation, self-concept, self-efficacy, and intrinsic value were identified as significant predictors of SRL in general. These significant predictors displayed a unique contribution to different types of SRL. The results show that intrinsic interest in kanji learning is necessary for cognitive and metacognitive regulation. A sense of positive self-concept, on the other hand, influences environmental regulation while self-efficacy beliefs facilitate behavioural regulation. Overall, self-concept was found to be the best predictor of the use of SRL. However, self-efficacy is another important factor since students who used behavioural regulation tend to use a wider variety of strategies to self-regulate their own learning. In this study, the interactions of identified motivational constructs and their possible effects on SRL are discussed. The study concludes with a discussion of practical and theoretical implications of the findings along with suggestions for future research.
