William will be an action therapist because he is not so much interested in understanding where this behaviour comes from or what its causes are but rather in inducing the kind of change that would get his client to refrain from engaging in the maladaptive behaviour. 

Insight therapy is used to help client's maladaptive behavior.

Explanation:

Social withdrawal, negative judgments, drinking, emotional masking etc are some of the symptoms. Action therapist does not work on the root cause but just on action to the problem without verbal communication. Biomedical therapist treats the patient through drugs and medicines. Relationship therapist deals with the problems pertaining to the relations among individuals.
