In a study of 145 preschool children, Tschann and colleagues (Tchann, Kaiser, Chesney, Alkon, & Boyce, 1996) found that children
with a difficult temperament (e.g., negative mood, distractibility) in high -
conflict families had higher levels of internalizing and externalizing behavior problems compared to children
with less a difficult temperament or a
less conflictual
home.
