Action-project method, action theory, career development - The Action Project Method developed over the last ten years by Richard A. Young (University of British Columbia), Ladislav Valach (University of Zurich) and their colleagues, is a powerful qualitative research method for use in vocational psychology and many other research fields in psychology. The method is based on the framework of Action Theory which conceptualizes action as goal-directed and intentional behavior, and as a joint-action between individuals. The systematic data gathering occurs in several stages, and data sources include observable behavior, internal processes and social meaning. The method is particularly suitable for addressing career issues, since the concept of career concerns individuals’ projects, goals, actions, and the social and relational context in which these projects are embedded.
