Direct assessment of quality of care in an applied behavior analysis center
Fifteen-second momentary time sampling gives BCBAs a fast way to spot and fix staff inactivity, client disengagement, and safety risks during sessions.
01Research in Context
What this study did
Grauerholz-Fisher et al. (2019) watched staff and kids inside a busy ABA center. They used 15-second momentary time sampling to score what was happening every few seconds.
They looked at three things: staff activity, client engagement, and any safety hazards in the room. The goal was to see if quick snapshots could catch problems early.
What they found
The short checks worked. The 15-second samples caught staff standing still, kids staring off, and toys on the floor that could trip someone.
Because the data were simple counts, supervisors could give feedback right after sessions.
How this fits with other research
LeBlanc et al. (2020) backs this up. Their lab study showed that intervals under three minutes give the best match to continuous recording. The clinic field test now proves 15-second MTS works in real life, too.
Springer et al. (1981) seems to disagree. That older paper says we should drop all discontinuous methods. The difference is time and place: 1981 was a theory piece, while 2019 and 2020 show actual data where short MTS caught problems continuous eyes might miss.
Goldman et al. (1979) and Parsons et al. (1993) did similar things in group homes. They used simple checklists or self-counts to boost staff interaction and safety. All three studies say the same thing: quick, cheap counts lead to fast fixes.
Why it matters
You do not need pricey gear or long forms. Set a 15-second timer on your phone, score staff activity, client engagement, and hazards for ten minutes, and hand the sheet to the therapist. One week of these micro-audits can lift session quality without eating your whole day.

03Original abstract
AbstractMomentary time sampling has been used to evaluate quality of care in several settings, including residential facilities and nursing homes. Given the growing number of behavior analysts providing center‐based applied behavior analysis (ABA) therapy to children with autism spectrum disorders, ABA centers are a new area in which assessing environmental indicators that might be correlated with the quality of care could be very important. Therefore, we extended these procedures to an ABA center, where we used momentary time sampling to assess staff behavior, client behavior, client condition, and environmental condition. The results demonstrated that this descriptive assessment can be a useful tool to obtain direct measures of variables that might affect quality of care. The general utility of this assessment, intervention plans for targets identified by this assessment, limitations of the assessment, and directions for future research in this area are discussed.
