This chapter will focus on investigating the quality of adult relationships and the association between attachment styles, support and features of problem relationships involving conflict or apathy. A primary focus will be on the partner relationship as the likely main attachment figure in adulthood, including past partner relationships, and those involving domestic violence. Reference will also be made to other supportive relationships, which can include both family members or friends. A self-esteem measure will be used to determine whether Insecure attachment styles relate to negative views of the self and how this contributes to risk of disorder. Details of the analysis can be found elsewhere (Bifulco, Moran et al. 2002b), but new analyses of domestic violence are presented.
