In this study, we explored how couples raising children with autism spectrum disorder negotiate intimacy, including what contextual and temporal factors influence these processes. We conducted conjoint interviews with 12 couples, employing grounded theory methodology to collect and analyze the data. Our results indicated that fostering intimacy in these couples' relationships involves partners working together to make key cognitive and relational shifts. Couples are aided or hindered in making these shifts by the degree to which they experience various contextual and environmental factors as resources or roadblocks. We also found that intimacy is not a fixed point at which couples one day arrive, but is an iterative process taking place over time and requiring work to develop and maintain.
