*Severity of self-harm behaviour	2.217	0.874	0.219	2.535	0.012
Stereotyped behaviour subscale of ABC	1.201	0.534	0.258	2.250	0.026

Adjusted R² for caregivers of normal children=0.042.
Adjusted R² for caregivers of children with ADHD=0.183.
Adjusted R² for caregivers of children with ASD=0.161.
*Severity was calculated by summing the scores of 3 items related to self-harm behaviour in the ABC scale.
ABC, Aberrant Behavior Checklist; ADHD, attention deficit hyperactivity disorder; ASD, autism disorder.
