What you need to know: Adults with ASD have an interest in sexuality. They engage in sexual behaviours and understand sexual vocabulary similarly to those in the general population. Yet, differences exist in terms of sexual orientation.
What is this research about?
There is a lack of research that examines the sexual behaviours and sexual interests of adults on the autism spectrum. Research in this area is important, as these adults exhibit deficits in the areas of social interaction and verbal and non-verbal communication. Previous studies have shown some differences in sexuality between adults with Autism Spectrum Disorder (ASD) and the general population.
What did the researcher do?
In this study the researchers compared two groups. One group was a sample of adults on the autism spectrum (82 total) and the other was a sample of adults from the general population (282 total). Participants completed an online survey that asked demographic questions, as well as questions about:
- sexual knowledge (sexual vocabulary);
- sexual experiences (examining experiences ranging from kissing to intercourse);
- and sexual orientation (heterosexuality, bisexuality, homosexuality, asexuality).
Each type of sexual orientation was rated on a scale of how much the participant endorsed that orientation.
What did the researcher find?
Researchers found that adults with ASD and those in the general population did not differ in their sexual experiences or their understanding of sexual vocabulary. Researchers found that adults on the autism spectrum were significantly more likely to indicate higher scores than the general population on the measures of:
- bisexuality (ASD group average = 4.47 and control group average = 1.60);
- homosexuality (ASD group average = 4.71 and control group average = 1.16);
- and asexuality (ASD group average = 1.29 and control group average = 0.27).
They also compared male and female ASD participants. Most scales did not significantly differ except for the heterosexuality scale. They found that female participants with ASD had significantly lower scores on the measure of heterosexuality than male participants with ASD. This difference was not seen between males and females in the control group.
How can you use this research?
This research helps further our understanding of sexuality and ASD by informing us that sexual orientation may express itself differently in those on the autism spectrum compared to the general population. Also, sexuality differs between males and females with ASD in terms of heterosexuality. This research is relevant to clinicians, parents, support workers, and most importantly, individuals on the spectrum.
