All of the following are research findings that support Patterson's coercion theory

except:

a. Children who are raised with ineffective, inconsistent discipline are more likely to
develop serious behavior problems than their peers who grow up exposed to
effective discipline.
b. Parents of children referred for treatment because of oppositional and aggressive
conduct are more critical and less positive in their interactions with their children
than parents of average children.
c. Training parents to use firm but non-coercive discipline has been found to be a
very effective way of treating children who are oppositional and aggressive.
d. Parents of children referred for treatment because of oppositional and aggressive
conduct are less involved in monitoring their children's behavior and more
permissive than parents of average children.
e. All of the above are research findings that support Patterson's coercion theory.
