ABSTRACT
Current classification schemes and empirical research have held that there are two dimensions of behavior: internalizing and externalizing (e.g., Achenbach, 1985). Internalizing behaviors are those that are directed inwardly, toward the self, and externalizing behaviors are directed outwardly, toward the environment. Emotional and behavioral disorders, then, are also delineated along these lines; internalizing disorders include anxiety, depression, fearfulness (or phobia), and social withdrawal, whereas externalizing disorders include those associated with conduct, hyperactivity, delinquency, and aggression.
