displays all the participants’ mothers’ ratings of their child’s mood (black bars), happiness (white bars), and interest
(striped bars) using the MSRIQ and GCARS. The first six bars (2 sets of 3 bars) represent the scores from the videos taken
during the initial baseline (pre-intervention) and the last six bars represent the two videos taken during the final ‘‘A’’ Phase
(post-intervention). Ashley’s mother (top panel) and Vince’s mother (middle panel) rated their children as happier, more
interested, and in a better mood following the play intervention using the MSRIQ and GCARS. Colt’s mother’s ratings (bottom
panel) did not change from pre- to post-intervention.
