The longitudinal relation between childhood autistic traits and psychosexual problems in early adolescence: The Tracking Adolescents' Individual Lives Survey study.

The team followed a group of Dutch children for four years. They scored each child’s autistic traits at age 10-12. Then they asked parents about the child’s psychosexual worries at age 12-15.

No therapy was given. The goal was to see if early social style predicts later sexual worries.

Kids who showed less social interest and poor social tuning at 10-12 had more parent-reported psychosexual problems three years later. The problems were mild but real.

Examples included worries about dating, body image, and crushes.

Chang et al. (2022) used the same Dutch cohort and pushed the clock forward. They found that the same early traits predict gender-dysphoric feelings in young adults. Together the papers show a steady line from childhood social style to teen worries to adult gender questions.

Boets et al. (2011) looked at girls only and found that high autistic traits delay the first period. The two studies seem opposite—one says traits speed sexual worries, the other says traits slow physical puberty. The gap makes sense: physical and psychosexual timetables are different clocks.

Stevens et al. (2018) and George et al. (2018) moved the question to adults. Both found that adults with high autistic traits more often identify as bisexual or gender-nonconforming. The 2015 paper sits in the middle: it captures the first stirrings of these issues in early adolescence.

You now have a timeline. Social-passive kids at 11 may need help before crushes, periods, and identity questions hit. Start social-sexual education early. Use plain words, visual stories, and peer role-play. Check in with parents each year. A ten-minute chat at 11 can prevent bigger worries at 15.
