Data from an ABAB design conducted by Thorne and Kamps (2008). These data were used as an example in Swan and Pustejovsky (2017). Academic engagement was collected via continuous recording (marked as "other") and inappropriate verbalizations were collected via event counting (marked as "count"). The variables are as follows:

  • Measure. Outcome measure description (academic engagement or inappropriate verbalizations).

  • Case. Participant identifier.

  • Session_number. Measurement occasion.

  • Outcome. Outcome scores

  • Trt. Treatment indicators.

  • Session_length. Length of the observation session.

  • Measure. The metric in which the outcome measurement is expressed (count or other).
