Abstract
D.Litt. et Phil.
This study aims at constructing a developmental model which can serve as a guide for the design and development of Web-based psychological interventions. It should be kept in mind that this study is grounded methodologically in a developmental research design but also uses this developmental research design as a basis for intervention design. Psychology has already made use of the Internet in terms of different applications but no formalised structure exists for the development of Web-based interventions. Due to this gap in knowledge the model needs to be developed by utilising existing models for intervention design and integrating them with existing models for the design of instructional and Web-based training. Due to the unique, adaptive nature of Web-based psychological interventions, it is necessary to also move beyond these models and focus on user and environmental characteristics which can be addressed during the development and design phases. In order to develop and refine the proposed model, a Web-based career guidance intervention will be developed and implemented. Users‟ feedback from their experience of this intervention will provide indications of the feasibility of the model and also suggest any modifications that should be made.
