Sexual understanding, sources of information and social networks; the reports of young people with intellectual disabilities and their non-disabled peers.
Teens with mild ID know less about sex and have fewer people to ask, so you must script both the lesson and the network.
01Research in Context
What this study did
The team asked teens with and without intellectual disability about sex. They used surveys and small group chats.
They wanted to know who the teens talk to about sex and how much they understand.
What they found
Non-disabled teens knew more facts and had wider friend circles.
Among teens with mild ID, boys scored higher than girls. That flips the usual pattern.
Kids with ID also named fewer trusted adults to ask.
How this fits with other research
Kangas et al. (2011) interviewed mothers who felt lost when talking about sex with their ID teens. The new teen voices match those moms’ worries.
van Timmeren et al. (2016) later saw the same knowledge gap in autistic young adults. The problem crosses diagnoses.
Austin et al. (2015) found that adults with mild ID like their small networks. Laugeson et al. (2014) show those same small nets limit sex facts. Same size, different cost.
Armas Junco et al. (2025) scanned every paper on ID and sexuality. They found almost none. The 2014 data still count because little has followed.
Why it matters
Your clients with ID get most sex facts from TV, siblings, or no one. Build a short list of safe people and rehearse how to ask. Write girl-only and boy-only lessons, because the usual gender strengths are reversed. One extra trusted name in their phone can cut risk later.

03Original abstract
BACKGROUND: Sexual development plays a vital part in young people's emotional adjustment. METHOD: This study compared the sexual understanding of 30 adolescents with mild intellectual disabilities (ID) and 30 non-disabled adolescents, along with their reports of where they obtained sexual information, and the nature of their social networks and support. RESULTS: As expected, the non-disabled young people had superior levels of knowledge. However, an interaction was found between group and gender. The non-disabled young women had a better grasp of sexual matters than men, whereas the opposite was the case for those with ID. The non-disabled young people reported more formal and informal sources of sexual information and described larger social networks than those with ID. CONCLUSIONS: These findings highlight the need to tackle the barriers to sexual knowledge faced by young people with ID, and the need to take account of the broader social context of their lives when doing so. This includes the attitudes to the developing sexuality of young women with ID in particular.
