Inflatable balls and cushions made of non-latex rubber can provide alternatives to sitting on the floor/ground or classroom chairs. This study tested the effect of inflatable cushions (wiggle cushions) placed on the floor for seating during circle time in typical preschool classrooms. The effect on attention was tested using alternating periods of usual seating and wiggle cushions. Four preschool classrooms (n = 25) were utilized, with two randomly assigned to the intervention condition (n = 15) and two as control (n = 10). Circle time was led by classroom teachers. Preschoolers' engagement was rated using five subscales of the Child Behavior Rating Scale (Mahoney and Wheeden 1999), a five-point Likert-type scale, from video recordings of a uniformly structured seven-minute period at the beginning of circle time. With use of wiggle cushions, there were statistically significant improvements in Attention and Persistence subscales (p = 0.002, 0.026 respectively). Teachers provided positive feedback for the intervention, indicating social validity. Results provide support for the use of wiggle cushions to enhance engagement during preschool circle time.
