Relationship Satisfaction Among Autistic Populations: How Partner Neurotype Influences Relationship Satisfaction Factors for Autistic Adults.

Background: Autistic individuals report high levels of interest in pursuing and maintaining romantic relationships but indicate fewer and less satisfying relationships when compared with non-autistic populations. In this mixed-methods study, we investigated the self-identified factors that contribute to successful romantic relationships for autistic adults with the additional goal of understanding if and how their partners' neurotypes may influence relationship satisfaction. Methods: We compared levels of relationship satisfaction among 106 autistic individuals by categorizing each participant into one of three groups based on the specific neurotype of their partner: (1) autistic/autistic (A/A) dyads; (2) autistic/neurotypical (A/NT) dyads; and (3) autistic/non-autistic but neurodivergent (A/ND) dyads. All participants completed a series of online surveys to gather information about their autistic traits, overall relationship satisfaction, reciprocal communication and support, and perceived impact of autism on relationships. Results: Across the three dyads, participants reported similar levels of relationship satisfaction, and we found no statistically significant differences when comparing the mean satisfaction of each sample group. Participants indicated a wide variety of positive and negative relational aspects, with a few themes changing in frequency based on partner neurotype. Participants with autistic partners tended to focus on an inherent and deep sense of understanding when discussing the positive aspects of their relationships, while those with non-autistic partners were more likely to discuss the presence of mutual support and accommodation. In addition to some differences in reported themes, participants tended to report that their autistic traits positively impacted satisfaction in A/A dyads, while those in A/NT and A/ND dyads tended to report that their autistic traits posed challenges in their relationships. Conclusions: The results of this study indicate that the neurotype of an autistic individual's partner may influence some of the reported positive and challenging aspects of their relationships. However, survey results indicate that autistic populations generally find comparable levels of satisfaction in romantic relationships irrespective of neurotype, which suggests that while partner neurotype may shape the enabling and barring factors for relationship success, it does not directly affect the overall health of a relationship. Finally, how an autistic individual perceives the impact of autism on their relationship may be affected by the neurotype of their partner. Community Brief:
