Assessment & Research

A social validation assessment of the use of microswitches with persons with multiple disabilities.

Lancioni et al. (2002) · Research in developmental disabilities 2002
★ The Verdict

Stakeholders see microswitch use as socially valid—use this evidence to win team buy-in.

✓ Read this if BCBAs writing assistive-tech goals for clients with multiple disabilities.
✗ Skip if BCBAs who only serve verbal adults with no tech needs.

01Research in Context

01

What this study did

Carr et al. (2002) asked people who know clients best to rate microswitch use. The team surveyed parents, teachers, and aides. They wanted to know if these stakeholders saw microswitches as acceptable and useful.

The survey compared microswitch sessions to regular interaction sessions. Raters scored both setups on social validity scales.

02

What they found

Stakeholders rated microswitch use as good or better than plain interaction. They saw it as fair, helpful, and worth keeping. The positive ratings held across different clients and settings.

No group saw the technology as cold or harmful. Most wanted to keep using it.

03

How this fits with other research

Lancioni et al. (2008) later tested the same idea with direct data. They ran a single-case study and also asked experts to rate social validity. Both papers show positive views, but the 2008 study adds hard behavioral numbers.

Rosenberg (1986) started the line of work. That study first showed microswitches can reveal preferences in people with severe disabilities. Carr et al. (2002) then asked, 'Do people actually like this approach?' The answer was yes.

Steege et al. (1989) proved microswitch assessments can cut self-injury for months. Carr et al. (2002) fills the gap by showing the same tools also feel right to families and staff.

Why it matters

You now have survey proof that teams view microswitches as acceptable. Use this when you write IEP goals or ask for funding. Show parents the 2002 ratings. Tell teachers the same tools that build head control or cut self-injury also feel positive in use. Start your next meeting with one simple line: 'Stakeholders rate microswitch use as fair and effective.'

03Original abstract

The purpose of this two-part study was to conduct a social validation assessment of microswitches versus interaction/stimulation conditions used with persons with multiple disabilities. In Part I, 32 teacher-assistant trainees were shown video-tapes reporting the use of microswitches versus interaction conditions for six children. In Part II, 40 teacher-assistant trainees or classroom aides and 44 rehabilitation staff were presented with video-tapes showing the use of microswitches versus systematic stimulation strategies for four adults. Raters scored the microswitch and the interaction or stimulation conditions on a 7-item questionnaire covering social/emotional and practical aspects. The microswitch condition was viewed as generally more positive than or comparable to the interaction or stimulation conditions. Main features of the findings and their implications are discussed.
