Data from an ABAB design conducted by Lambert, Cartledge, Heward, & Lo (2008). The variables are as follows:

  • case. Student identifier.

  • treatment. Factor indicating treatment or control condition. SSR = single-subject responding. RC = response cards.

  • phase. Study phase (including both control and treatment condition)

  • time. Measurement occasion.

  • outcome. Intervals with disruptive behavior, as measured by a partial interval recording procedure with 10 ten-second intervals per session.
