Reciprocal communication between couples is central to sustaining strong intimate relationships. Given that Asperger’s Syndrome (AS) affects communication and social reciprocity, adults with this disorder are vulnerable to experiencing difficulties in relating to their “neurotypical” (NT) partner. As reported in a previous paper, prompt dependency was found to be a compensatory mechanism for some of the communication difficulties within AS-NT relationships. This paper draws on the same data-set to describe the impact of prompt dependency on AS-NT relationships. The research reported here is also used to derive a theoretical model that illustrates how a cycle of prompt dependency results in a communication “roundabout” for partners. Implications for practice and further research are discussed.
