Autonomy Support, Need Satisfaction, and Motivation for Support Among Adults With Intellectual Disability: Testing a Self-Determination Theory Model.

Frielink et al. (2018) · American journal on intellectual and developmental disabilities 2018
★ The Verdict

Offer real choices and reasons during daily support to spark autonomy, motivation, and happiness in adults with mild ID.

✓ Read this if BCBAs writing active treatment plans for adults with mild-borderline ID in residential or day programs.
✗ Skip if Clinicians serving only non-verbal or moderate-profound ID where survey methods do not apply.

01Research in Context

01

What this study did

Frielink et al. (2018) asked adults with mild-borderline intellectual disability about the help they get each day.

They used a survey that measures how much staff give real choices, listen, and explain why tasks matter.

The team then looked at whether higher choice predicted happier feelings and stronger motivation.

02

What they found

Adults who felt staff supported their choices also felt more in control, more connected, and more motivated.

That chain of good feelings then predicted higher well-being.

In short, small daily choices add up to big life gains.

03

How this fits with other research

Perry et al. (2024) followed the same adults for four and a half years and found the same chain still held, showing the effect lasts.

Gabriels et al. (2001) showed moving people from large facilities to community homes raised self-determination, matching the new data.

Fahmie et al. (2013) looked at adults with mild-moderate ID in the Netherlands and saw little real choice in planning meetings, seeming to clash with the positive story here. The gap is explained by ID level: the current study sampled only mild-borderline adults who can answer surveys, while the Dutch group included moderate ID where staff still dominate talks.

04

Why it matters

You can lift client mood without new programs. Just add two minutes of choice and rationale to everyday routines. Offer two shirts, ask which chore to do first, and explain why tooth-brushing matters. These micro-moments satisfy the need for autonomy and relatedness, setting off a chain that ends in better well-being.

03Original abstract

The tenets of self-determination theory as applied to support were tested with structural equation modelling for 186 people with ID with a mild to borderline level of functioning. The results showed that (a) perceived autonomy support was positively associated with autonomous motivation and with satisfaction of need for autonomy, relatedness, and competence; (b) autonomous motivation and need satisfaction were associated with higher psychological well-being; (c) autonomous motivation and need satisfaction statistically mediated the association between autonomy support and well-being; and (d) satisfaction of need for autonomy and relatedness was negatively associated with controlled motivation, whereas satisfaction of need for relatedness was positively associated with autonomous motivation. The self-determination theory provides insights relevant for improving support for people with intellectual disability.
