^*P < 0.05,

^**P < 0.01,

^***P < 0.001, bold results P < 0.05.

^†Model 1 (the first row of each dependent variable) is status entered on its own; Model 2 (the second and third rows of each dependent variable) is the final model with status and behaviour problems entered together.

TD, typical development; ID, intellectual disability; CBCL, Child Behavior Checklist.
