The present survey basically deals with the meaning of open spaces in (urban and suburban) residential areas as a source of (unintentional and/or by chance) social interaction. The assumption, that people dealing with structural discrimination and/or health restrictions are much more dependent on the resources of their immediate living environment, when it comes to fulfill their needs, is mainly relevant in this content. This applies in particular to the needs for social contact and interaction, the meaningful use of time and the opportunity of social inclusion. It is supposed, that the immediate living environment serves some kind of compensation possibilities for those people, who became, because of bio-psycho-social limitations, very reliant on their residential area. One further question this study deals with, is the meaning of open spaces, related to the creation and development of personal and individualized social capital on one hand, and related to the expansion of individual spheres of action on the other. In this context its useful to differentiate between unaccompanied and professionally constructed and staged open spaces (which, in context of this survey, will be identified as accompanied opportunity structures). Following up on this, the main focus lies on role and importance of professional guidance and supervision in case of accompanied opportunity structures. All of these especially against the backdrop of current programs, which strongly focus on the development of self-supporting structures, to be soon transferred into the users (citizens) management and self- responsibility. And because, related to this approach, there already is empirically - based criticism which points on the increase of discrimination-effects by neglecting differences in access and resources, this survey is devoted to the discussion of influences, which can cause a strong domestic orientation. Originating from the identified (user) groups and based on exemplary case histories, it is necessary to explore, how different factors of using accompanied opportunity structures interact with the formation of social capital and the development of action competence.
