South African adolescents are more likely to participate in high-risk behaviours, because they are exposed to high-risk environments that have a negative impact on them. The choices that adolescents make during this explorative life stage will influence and determine certain outcomes of their adult lives. Therefore, it is crucial to improve adolescents’ psychological well-being, as they are the future generation adults. Adolescents with behaviour problems form a unique population who do not respond effectively to traditional therapy, and researchers are continuously searching for more effective ways to reach this population. Equine-assisted therapy (EAT) is an intervention that has been proven to be effective with this population and to provide better outcomes than traditional psychotherapy. Although the value and positive effects of EAT has been proven, there is a gap in the literature concerning research on this topic, especially with regard to research conducted by means of quantitative methods. The overarching goal of this study was to evaluate and refine an EAT programme aimed at improving the psychological well-being of boys in a school of industry. This goal was attained by utilising a quantitative, experimental research design. The Solomon four-group design was applied, because it effectively controls pre-test sensitisation and provides the best control against threats to internal validity. The sample was selected from a school of industry near Bloemfontein, which provides residence to a group of adolescent boys who display behaviour problems. The 40 boys (N = 40) included in the sample were divided into two experimental groups of 10 boys each and two control groups of 10 boys each. During the course of the study, one of the boys withdrew and the sample was reduced to 39 boys. The programme was administered to the boys in the experimental groups. Before the programme commenced, one of the experimental groups and one of the control groups completed the pre-test. The psychometric instruments used were a biographical questionnaire, the Satisfaction with Life Scale and the Coping Orientations to the Problems Experienced Questionnaire. The boys then completed the EAT programme which consisted of eight sessions, each with its own outcomes and designed to improve subjective well-being and coping. After completion of the programme, all four groups completed the post-test consisting of the same psychometric instruments as the pre-test. The results showed that the programme significantly improved the boys’ subjective well-being. The boys’ problem-focused coping, emotion-focused coping and dysfunctional coping were also increased significantly. These improvements can be attributed directly to the programme, because pre-test sensitisation was controlled. The study found that the EAT programme had a significant positive effect on the boys’ subjective well-being and coping. The conclusion can be drawn that the programme significantly improved the boys’ psychological well-being. The programme was evaluated and refined, and recommendations were made for its future use. / PhD (Psychology), North-West University, Potchefstroom Campus, 2014

Over the last decade the focus has shifted to ensure a holistic view of employee well-being in organisations by focusing on both physical and psychological well-being. Previous research suggests that work characteristics and psychological work-related well-being influence both the individual (i.e. health) and organisational outcomes (i.e. commitment, safety, productivity, etc.). Moreover, the increasing importance of focusing on work-related psychological well-being of employees is evident in legislation from around the world. In South Africa the Occupational Health and Safety legislation, spesifically the Construction Regulations, also recognises the importance of the psychological well-being of employees and refers to it as ?psychological fitness?. However, no clear definition or instrument for psychological fitness exists. Similarly, no instrument exist to measure work characteristics of blue-collar workers. The objectives of this research were 1) to propose a defintion for psychological fitness of blue-collar employees 2) to propose a theoretical framework to better our understanding of psychological fitness 3) to develop a psychological fitness instrument for blue-collar employees that is suitable for the South African context 4) to test the psychometric properties of the newly developed psychological fitness instrument 5) to develop a work characteristics questionnaire for blue-collar mine workers to gain insight into their work experiences, and 6) to evaluate the psychometric properties of the newly developed job demands-resources scale for blue-collar mine workers. The empirical study consisted of two phases. During the first phase, following an extensive literature review, a definition and theoretical framework for psychological fitness was proposed. Thereafter, a new instrument for measuring psychological fitness was developed and tested. An instrument for measuring the work characteristics of blue-collar mine workers has also been developed to further the understanding of their work experiences. During the second phase, the psychometric properties of the newly developed psychological fitness instrument were tested (i.e. factorial validity, factorial invariance, reliability and external validity; N = 2769). Furthermore, the psychometric properties of the newly developed job demands-resources scale for blue collar workers were also investigated (i.e. factorial validity, reliability and the relationship with theoretically relevant external variables; N = 361). During the conceptualisation process, the definition of psychological fitness has been proposed based on previous work-related well-being literature. The work-related well-being concepts, distress and eustress were proposed as indicators of psychological fitness. Therefore, psychological fitness was defined as a state in which an employee display high levels of emotional and mental energy and high levels of psychological motivation to be able to work and act safely. The dimensions of burnout and engagement were proposed as possible indicators of psychological fitness and included exhaustion, mental distance, cognitive weariness, vitality and work devotion. Furthermore, the underlying work-related well-being theories and models were identified as the theoretic framework to enable the development of a questionnaire for psychological fitness. In order to ensure that the low literacy employees understand the meaning of each questionnaire close attention has been paid during the development of items. Firstly, the psychological fitness instrument (SAPFI) for blue-collar employees has been translated into all the official languages of South Africa following a multistage translation process. Secondly, the job demands-resources scale for blue collar mine workers (JDRSM) has been translated into the three most commonly spoken languages (Sesotho, isiXhosa and Setswana) by employees working in this specific mine. During this phase various problematic items were identified and eliminated from both questionnaires using the Rasch measurement model. The final phase included the validation study where the psychometric properties of both the new instruments were investigated. The SAPFI results provided evidence for factorial validity, factorial invariance, reliability and significant relations with external variables of the distress scale. Although evidence was provided for the factorial validity, reliability and external validity of the eustress scale, factorial invariance could not be confirmed. Furthermore, the JDRSM results provided evidence for the factorial validity, reliability (except for the workload scale) and external validity. Recommendations for future research were made. / Thesis (Ph.D. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2011.

Rapid escalation of Subclinical Eating Disorders (SED) in the form of high levels of body–dissatisfaction (BD) and drive for thinness (DT) globally and locally, and the at–risk status of university females are underscored by recent studies. As yet there exists no South African program tailored to the needs of afflicted female students and which includes a risk–protective focus grounded in Positive Psychology theory. In this chapter a theoretical overview on the nature and definition of SED, its prevalence and the rationale for a risk–protective focus grounded in Positive Psychology theory are provided. Thereafter three preliminary South African studies, namely two correlation studies (De Pãz Fransisco, 2007; Kirsten, Du Plessis & Swanepoel, 2010) and the Weight Over–concern and Well–being program of Kirsten, Du Plessis and Du Toit (2007) are discussed. Findings of these preliminary studies highlight the promise of utilizing Positive Psychology theoretical approaches to practically significantly reduce risk factors and promote protective factors. As such, Well–being therapy (Fava & Ruini, 2003) that promotes the six dimensions of psychological well–being (Ryff & Keyes, 1995), and Self–Determination Theory (Ryan & Deci, 2000) that can promote true self–esteem in the form of self–determination and mindfulness (Kabat–Zinn, 1998), with its inherent self–compassion, kindness and self–forgiving manner, show promise. More in–depth studies with larger samples are however needed. / Thesis (M.A. (Clinical Psychology))--North-West University, Potchefstroom Campus, 2012.
