The purpose of this study was to investigate and analyse the consequences of being diagnosed with Asperger syndrome during adulthood. My ambition was to investigate the participants’ perspective on how the diagnosis affected their lives and relationships with their partners. To answer the purpose three questions were formulated: (1) How did the participants experience being diagnosed with Asperger syndrome? (2) What have the diagnosis meant to the participants’ self-image and self understanding? (3) Have the diagnosis influenced the participants’ understanding of their partners and have the diagnosis influenced the partners’ understanding of the participants? The study is based on qualitative interviews with two men and two women living in Stockholm, Sweden. The theoretical framework is Symbolic interactionism and Goffmans Stigma concept. The results show that the participants found the diagnosis positive because it provided an explanation and understanding of the difficulties they had experienced. In extension, the majority of the participants experienced a more positive self-image and a better understanding between themselves and their partners. Negative experiences were reported as well, mainly chock, bitterness and grief.
