Rates per minute of play behaviors by group
| ASD sibling group (mean, SD) (n = 17) | Other delays sibling groups (mean, SD) (n = 12) | No delays sibling groups (mean, SD) (n = 29) | TD control group (mean, SD) (n = 19) | |
|---|---|---|---|---|
| Functional play | 1.28 (1.80)a | .91 (.64)b | 1.58 (1.50)b | 1.42 (.82)b |
| Object directed | 1.00 (1.84) | .54 (.52) | .86 (.77) | .73 (.54) |

| Other directed | .01 (.03)a | .12 (.21)b | .26 (.55)b | .18 (.34)b |
| Symbolic play | .08 (.21) | .11 (.19) | .12 (.22) | .11 (.22) |
| Functional repeated play | 1.39 (1.56) | .77 (1.05) | 1.22 (1.81) | 1.64 (1.44) |
| Non-functional repeated play | 2.30 (2.26)a | 1.23 (.92)a | 2.11 (4.02)a | .54 (.98)b |
| Total play acts | 5.05 (3.65) | 3.02 (1.99) | 5.03 (6.75) | 3.74 (2.74) |
Group contrasts are indicated by the letters a and b where different letters mean significant differences between groups at the p < .05 level. Each sibling group was only compared to the TD control group
