Factors Influencing the Research Participation of Adults with Autism Spectrum Disorders.

Haas et al. (2016) asked adults with autism and intellectual disability why they join—or skip—research projects.

The team used mixed methods: surveys plus open interviews with both adults and their carers.

They wanted to map every barrier and booster that shapes long-term study participation.

Personal values won over ease. Adults joined when the study matched their interests, even if it cost time.

Carers added a second layer: travel distance, tight schedules, and unclear consent forms kill turnout.

In short, convenience matters, but meaning matters more.

Adams et al. (2021) ran a survey that repeats the same pattern: adults with ID say "yes" to research once they trust you.

The two papers differ in design—mixed methods versus survey—but both point to the same lever: build trust and value first.

Peters et al. (2013) warned that consent pages full of jargon scare people off; Kaaren’s finding on unclear forms backs up that early warning.

Schiltz et al. (2023) show we need autistic adults in long studies to track mental-health trends; Kaaren tells us how to keep them there.

If you run staff training, parent groups, or adult services, use these hooks. Start recruitment by explaining how the study helps the participant’s own goals, not just science. Offer flexible times, ride shares, or virtual visits to cut the hassle. Small fixes raise retention and give the field the adult data it still lacks.
