Scale for rating child’s interest, adapted from Koegel and Egel (1979)

Low Interest (1–0)	(1): Child remains in the area of the activity but looks bored and is uninvolved. The child may spend much time looking around and little time attending to the task. The child may engage in behaviors unrelated to the activity.	(0): Child looks bored and attempts to leave the area of the activity. Child may attempt to avoid or escape the task by throwing tantrums, running away, whining, throwing materials, crying, or refusing to perform the task.
Neutral Interest (3–2)	(3): Child complies with the instruction, but does not appear eager to participate in the activity. The child generally focuses on the clinician and stimulus materials.	(2): Child generally complies with the instructions, but does not appear eager to participate. There may be moments of staring or inattention, “toying with stimulus materials” and being fidgety.
High Interest (5–4)	(5): Attends readily to task; responds readily and willingly. Child is alert, eager, and involved in activity. Child attends to the clinician and/or the stimulus materials intently during the trials.	(4): Attends and responds to task readily. Child is fairly alert, eager, and involved in the activity and frequently attends to the clinician and/or stimulus materials during the trial.
