Teaching persons with profound multiple handicaps: a review of the effects of behavioral research.

Goldstein et al. (1991) read every behavioral study they could find on people with profound multiple handicaps. They looked for proof that the teaching tricks we use actually make life better, not just change behavior. After sorting dozens of papers, they concluded we still lack good evidence for real-life gains.

The team saw that behavioral procedures could alter responses, such as increasing hand-raising or reducing self-hits. Yet almost none of the studies linked those changes to meaningful life outcomes like more friends, safer homes, or fuller days. In short, we were winning small battles while losing the quality-of-life war.

Reichow (2012) paints a brighter picture. Five meta-analyses show early intensive ABA raises IQ and daily skills in preschoolers with autism. The gains are medium-sized and hold across tests, giving later studies a benchmark the 1991 paper never had.

Eldevik et al. (2006) adds a caution. Low-intensity ABA (about 12 hours a week) still beats eclectic care, but the gains are tiny and may not matter day-to-day. Their data extend the 1991 warning: without enough hours, even solid methods can fall short of meaningful change.

Yuwiler et al. (1992) offers hope. Eleven mothers with developmental disabilities learned child-care skills to 90 % mastery through behavioral parent training, and kids stayed healthy for months. This single-case success shows meaningful life improvement is possible when teaching is precise and linked to real needs.

For BCBAs, the takeaway is simple: measure what matters. After each program, ask if the learner now eats lunch with peers, sleeps through the night, or chooses their own clothes. If the answer is no, boost intensity, tweak targets, or pick a new measure. Tie every graph to a life outcome parents can feel next week, not just a statistic you can publish next year.
