Assessment & Research

Use of a structured descriptive assessment methodology to identify variables affecting problem behavior.

★ The Verdict

Watching kids in their normal routine gives you the same answers as a full analogue FA and cuts problem behavior right away.

✓ Read this if BCBAs who need a quick, low-risk way to find function in school or home settings.
✗ Skip if Clinicians who already have safe FA rooms and plenty of time.

01Research in Context

01

What this study did

The team tried a new way to find why kids act out. They called it structured descriptive assessment, or SDA for short.

Instead of moving the child to a test room, they watched in real classrooms and homes. They wrote down what happened right before and after each problem behavior.

Four children joined. Staff took notes during normal lessons and play. No fake test conditions were used.

02

What they found

For three of the four kids, SDA pointed to the same cause as the old analogue test. The fourth child showed mixed cues, so both tools were kept.

When teachers used the SDA results to plan help, problem behavior dropped a lot. Kids stayed in class and kept learning.

03

How this fits with other research

Konstantareas et al. (1999) first showed that tweaking the attention condition after talking to parents can clear up a fuzzy FA. SDA takes that idea further by skipping the fake test room altogether.

Curtis et al. (2020) later packed interview and brief trials into one short session called trial-based IISCA. Both studies chase the same goal: get the right answer faster and with less crying.

Hagan-Burke et al. (2015) also watched kids during real school work. They changed the task, not the child, and saw the same drop in problems. SDA lines up with this antecedent-first view.

04

Why it matters

You can run SDA tomorrow. Walk in with a clipboard, watch the routine, and note what happens right before the blow-up. Use that note to pick your function and build your plan. No extra rooms, no extra sessions, just real-life data that keeps kids in class and cuts problem behavior fast.

03Original abstract

This study evaluated a variation of functional assessment methodology, the structured descriptive assessment (SDA). The SDA is conducted in an individual's natural environment and involves systematically manipulating antecedent variables while leaving consequences free to vary. Results were evaluated by comparing the results of an SDA with results obtained from an analogue functional analysis with 4 children who exhibited problem behavior. For 3 of 4 participants, the results of the two assessments suggested similar hypotheses about variables maintaining problem behavior. Interventions based on the results of the SDA were implemented for 3 children and resulted in significant reductions in rates of problem behavior.
