A thesis submitted in partial fulfillment of a PhD in Community Psychology at the University of Zululand, South Africa, 2012. / Ongoing global crises impact negatively on human health. International comparison studies may improve health promotion. A community psychology, appreciative inquiry was conducted into local staff perceptions of selected child and adolescent mental health interventions in the Kent and Zululand regions of the United Kingdom and South Africa respectively. The Kent findings, supported by a quasi-experimental investigation, indicated that intervention was beneficial, the mental health practitioner role had value and additional mental health practitioners should be employed. The Zululand findings, complemented by a single client case study, suggested that intervention provided a valuable people focused programme, and that additional emphasis should be placed on promoting the intervention, its structure and staffing. Evaluative comparisons thus illustrated the differential effectiveness of the respective interventions. The Kent service could learn from the way in which the Zululand intervention was people orientated and the Zululand programme could learn from the way in which the Kent intervention was structured and organized. Findings highlighted the ongoing need to evaluate existing models of community psychology, create new models, and the temporal and contextual nature of any such models.
