Practitioner Development

Training staff serving clients with intellectual disabilities: a meta-analysis of aspects determining effectiveness.

van Oorsouw et al. (2009) · Research in developmental disabilities 2009
★ The Verdict

Lectures alone fade fast; add on-the-job coaching with praise and correction to lock in staff skills.

✓ Read this if BCBAs who train direct-care staff in group homes, schools, or day programs.
✗ Skip if Researchers looking for learner outcomes rather than staff training.

01Research in Context

01

What this study did

The team looked at 55 staff-training studies done between 1980 and 2007.

All studies served adults or kids with intellectual disability.

They compared lecture-only, hands-only, and mixed training packages.

02

What they found

Lecture plus on-the-job coaching won by a large margin.

Verbal feedback, praise, and quick correction were the active pieces.

Lecture alone gave weak or short-lived gains.

03

How this fits with other research

Yaw et al. (2014) later tested the same mix in a single experiment.

They showed one short lecture plus five minutes of weekly feedback doubled data-sheet accuracy.

Blackman et al. (2022) seemed to disagree at first.

They found that just watching and recording data helped only a few trainees.

The gap closes when you see Blackman left out praise and correction.

The 2009 recipe still holds: you need all three ingredients.

04

Why it matters

Stop running one-off in-services and hoping skills stick.

Pair any new lecture with real-time coaching that includes praise, correction, and brief feedback.

Track one simple skill this week and give feedback on the spot.

You should see staff hit a large share accuracy within five shifts.

03Original abstract

The last decades have seen increased emphasis on the quality of training for direct-care staff serving people with intellectual disabilities. Nevertheless, it is unclear what the key aspects of effective training are. Therefore, the aim of the present meta-analysis was to establish the ingredients (i.e., goals, format, and techniques) for staff training that are related to improvements of staff behaviour. Our literature search concentrated on studies that were published in a period of 20 years. Fifty-five studies met the criteria, resulting in 502 single-subject designs and 13 n>1 designs. Results revealed important information relevant to further improvement of clinical practice: (a) the combination of in-service with coaching-on-the-job is the most powerful format, (b) in in-service formats, one should use multiple techniques, and verbal feedback is particularly recommended, and (c) in coaching-on-the-job formats, verbal feedback should be part of the program, as well as praise and correction. To maximize effectiveness, program developers should carefully prepare training goals, training format, and training techniques, which will yield a profit for clinical practice.
