Which factor(s) does NOT influence the effectiveness of a therapeutic approach?

None of the above

There are various types of psychotherapy. Some of them focus on acquiring self-understanding; other therapies are more action-oriented. All approaches hinge on the basic issue of helping the patient overcome her/his debilitating condition. The effectiveness of a therapeutic approach for a patient depends on a number of factors such as severity of the disorder, degree of distress faced by others, and the availability of time, effort and money, among others.
