'In his diploma thesis Benjamin Stollreiter dealt with the interconnection of work engagement and burnout. By using an impressively profound basis of previous research approaches he successfully merges previously not sufficiently combined theoretical approaches. With precision in language and argumentation Mr. Stollreiter derives from the interplay of occupational settings, personal characteristics and an employee's individual circumstances, how personal resources are consumed and professional identities are destabilized. Hence, on the basis of his theoretical analysis Mr. Stollreiter develops different hypotheses, which he evaluates by using a clinical sample of burnout inpatients. He concludes that especially role conflicts - at the job, but also between work and family roles - increasingly have to be put in the focus of burnout research and -prevention. Specific recommendations for organizations are given. With his work, Mr. Stollreiter goes beyond the current state of literature and impressively enriches the discussion of an extraordinarily dynamic field of research. In addition to his extremely profound literature review Mr. Stollreiter impresses with his superb empirical analysis.' Prof. Dr. Ralf Lanwehr
