The present thesis concentrates on goal striving in the realm of personal goals and is dedicated to the investigation on antecedents and consequences of approach and avoidance motivation in personal goals within work and private life domains. Previous research has focussed mainly on stable dispositions as antecedents of approach and avoidance goal selection and cannot explain temporary, individual changes of approach and avoidance goal adoption. Thus, in Part I of the present thesis it is investigated whether the amount of personal resources affects
approach versus avoidance goal adoption. Part II mainly considers whether avoidance goal striving and affective self-control are related to increased conflict between personal goals within work and private life domains. Seven studies are reported in this thesis. Two longitudinal studies, one scenario experiment and one online-experiment of Part I reveal that a large amount of resources affects the adoption of approach goals. Furthermore, this relationship is mediated by the participants’
outcome expectancy. In Part II, two longitudinal studies and one scenario-study demonstrate that avoidance goal striving within different life domains and affective self-control are related to enhanced goal conflict which, in turn, leads to impairment of performance and well-being. The results of the seven studies have important theoretical implications. First, they complement existing findings on antecedents of approach and avoidance goals. Thereby the amount of resources is highlighted as an important determinant which is probably more
eligible to predict the individual change of approach and avoidance goal selection. In addition, they pinpoint to outcome expectancy as a mediating mechanism of the relationship between resources and approach versus avoidance goal adoption. Second, they reveal that avoidance goals and affective self-control account for increased goal conflict. Finally, it is demonstrated that goal conflict not only impairs well-being but also performance.
