A replication to increase happiness indices among some people with profound multiple disabilities.
Handing over a favorite item for a few minutes reliably raises observable happiness in most people with profound multiple disabilities.
01Research in Context
What this study did
The team ran a simple ABAB reversal with four adults who had profound multiple disabilities. Each session lasted a few minutes. Staff gave the person their favorite toy, music, or vibration cushion and watched for smiles, laughs, or relaxed faces.
They counted these happy signs and compared them to baseline periods with no preferred items.
What they found
Three of the four adults showed more happy signs when the items were present. The fourth person did not smile more, but showed fewer unhappy signs like crying or grimacing.
The gains appeared right away and disappeared when the items were taken away, then came back in the final phase.
How this fits with other research
Carraro et al. (2012) worked on the flip side: they cut anxiety in adults with mild ID using a 12-week exercise plan. Andronis et al. (1997) shows you can boost positive affect in minutes, not months.
Douma et al. (2006) used a Snoezelen room and saw the same after-glow—brief sensory fun lifted engagement later in the day. Both studies say the same thing: give rich, liked sensations and mood rises.
Crossman et al. (2018) moved past mood and taught kids with autism to play on their own. Preferred items sparked happiness first; chaining then turned that spark into useful leisure skills.
Why it matters
You do not need fancy gear. Grab the client’s favorite song or squishy toy, run a quick reversal to be sure, and you have a low-cost way to add joy to the day. Happy clients tend to show less problem behavior and are easier to teach. Use these mini fun breaks before hard tasks or when you see signs of boredom.

03Original abstract
A replication of Green and Reid was made for four people with profound multiple disabilities by systematically increasing their happiness indices in a Fun Time activity during which their preferred stimuli were provided. In ABAB reversal designs, 3 of the 4 participants replicated the demonstration of the happiness indices, while the fourth individual showed reduced unhappiness indices when his preferred stimulation was presented. These effects were obtained despite the selection of preferred stimuli without formal assessment procedures and the use of brief training procedures for staff providing the stimulation. A subgroup of three individuals with profound multiple disabilities and minimal (almost no) movement failed to show any indices of happiness or unhappiness with this procedure. Uses for happiness indices were discussed. Alternative programming was suggested for individuals who failed to show any indices of happiness.
