Comparing functional analysis and paired-choice assessment results in classroom settings.

The team compared two ways to find why students act out. One way was a full functional analysis. The other was a quick paired-choice test.

Four teens with intellectual disability joined. All showed problem behavior in class. The study ran in their normal classroom.

Both tools pointed to the same social payoff for three of the four teens. For example, one teen worked for teacher praise, and both tests caught it.

The paired-choice tool matched the longer test most of the time. Teachers could get the same answer faster.

Prasher et al. (2007) looked at many studies and found the kind of test you pick changes how well later treatment works. Our study adds a new, faster test to that list.

Dugan et al. (1995) also compared methods. They used lag-sequential watching instead of paired-choice. Both studies say you can trust a shortcut, but the shortcut must fit your setting.

Taylor et al. (2018) went further and used a full-day function-based plan after their test. Our quick test could feed into their plan, saving start-up time.

You can swap a five-minute paired-choice trial for a long functional analysis when time is tight. If the quick test gives a clear answer, move straight to teaching a replacement skill. If the answer looks muddy, run the full test. Either way, you start class with solid data, not guesswork.
