Increasing one aspect of self-determination among adults with severe multiple disabilities in supported work.

Researchers worked with three adults who had severe multiple disabilities. All three had jobs in community work sites with staff support.

The team set up two work conditions at each site. One condition had extra assistive tools so the worker could do more steps alone. The other needed more staff help.

During sessions, staff asked each worker to pick which condition they wanted. The adults learned they could choose the setup that gave them the most independence.

Every adult quickly learned to pick the more-independent condition. They kept choosing it day after day.

The simple act of offering a choice let the workers control their own level of independence. Self-determination went up just by rearranging the environment.

Conyers et al. (2002) showed that you must first check if clients can tell the choices apart. Their quick discrimination probe predicts which choice format will work. Use their probe before you offer condition choices.

Shih et al. (2012) used a $10 wireless mouse so stroke patients could trigger their own leisure items. Both studies prove that simple tech plus client control boosts adaptive responses. The mouse study extends the choice logic to a new population.

Adams et al. (2021) scoping review warns we have lots of parent opinions on self-determination but almost zero home-based interventions. The current study fills that gap by giving you a ready-to-use environmental strategy you can teach families tonight.

You can grow self-determination in under a week without new staff or gear. Just identify which job steps the client can already do alone, bundle those into one “independent” condition, and offer it side-by-side with the “staff-help” condition. Ask, “Which way do you want to work today?” and honor the choice. Start with a discrimination check from Conyers et al. (2002) to be sure the client sees the difference. This one change can replace hours of prompting and still give you measurable gains in autonomy.
