Psychotherapist: The troubles from which a patient seeks relief through psychotherapy do not have purely internal causes; rather, those troubles result in part from the patient's relationships with other people. Hence, to help the patient heal, need for positive change in those relationships.
What this question is testing
Conclusion
Therapists MUST focus on the patient's relationships. No choice about it.
Evidence
The patient's problems are not all in their head — they partly come from their relationships with other people.
Evaluate
The jump here: But does it? Maybe a therapist could help a patient heal entirely by working on internal responses — building coping skills, changing thought patterns — without ever touching the relationships themselves. The argument needs an assumption that internal-only treatment would not be enough. Otherwise, why would the relational focus be mandatory?
Goal
Find the assumption that makes the relational focus necessary: internal-only treatment cannot heal the patient.
