Psychological stress in people with profound mental retardation.
People with profound ID show clear body signs of stress during everyday events—check heart rate before labeling behavior as willful.
01Research in Context
What this study did
Roeyers (1996) watched adults with profound intellectual disability during normal days.
Staff tracked heart rate and breathing while the adults did everyday things like exams, meals, and being watched.
The goal was to see if common events cause hidden stress.
What they found
Almost every adult showed higher heart rate and faster breathing during routine events.
The biggest jumps happened during tests and when staff observed them.
Even happy events like music raised vital signs, not just scary ones.
How this fits with other research
Meyns et al. (2012) later saw the same link in severe ID, but used skin temperature drops to spot negative mood.
Vos et al. (2013) went further and proved that breathing and heart-rate data match the emotion codes you already use.
Matson et al. (2009) seems to disagree: adults with mild ID said peer fights cause the most stress, not exams. The gap is real—people who can talk worry about social fights, while people with profound ID stress about being watched.
Why it matters
Before you call a behavior “attention-seeking,” take a 30-second pulse or watch chest rise. If numbers climb, the client feels stress, not mischief. Use this quick check to decide when to give space, slow the task, or offer a break.

03Original abstract
Does emotional stress in people with profound mental retardation occur and does it result from simple stimuli of daily living? Can this be measured by recording vital signs? To obtain answers, the histories of stress and stress diseases, and the behavioral characteristics of 163 institutionalized adults with developmental disabilities were evaluated; vital signs, temperatures and bodily expressions of 35 subjects from this sample were monitored. All but two of the 35 subjects had elevations of heart rate, blood pressure, respiration rate, core body temperature, and changes in peripheral temperature. Reactions occurred with unpleasant and pleasurable stimuli, and were greatest at clinical examinations and when the subjects were stared at. Responses were best demonstrated by heart rate, respiration rate, blood pressure and temperature. Such reactions result from the insecurity of people whose disabilities prevent them from adjusting to perceived threats.
