Family experience in a regional participant contact registry for research on intellectual disability.

Laugeson et al. (2014) sent a short survey to families already listed in a regional research registry for people with intellectual disability. They asked why families joined, how they felt about being contacted, and what problems they hit.

Most families said they signed up to help others and had a good overall experience. They also listed real-world hassles: hard-to-read letters, short notice, and slow replies from study teams.

Frankena et al. (2015) scoped 26 papers and found the same warm motives and the same roadblocks, so the survey lines up with the wider literature. Matson et al. (2011) saw a study crash when only 7 % of adults with ID returned consent forms; the registry families now explain why—proxy distrust and clunky mail. Ferreri et al. (2011) ran a trial that kept 75 % of women with ID until guardian consent dropped the rate to 61 %; the survey echoes guardian consent as a key logjam.

You can boost future recruitment by writing letters at a fifth-grade reading level, giving two-week notice, and adding a phone option. Copy those three tweaks into your next IRB packet and you may cut dropout before consent is even signed.
