I would like to see the peer review this study and see it replicated before drawing hard conclusions. As for mental disorders this article does not differentiate enough and over generalizes.   Without drugs and blood test monitoring persons with bipolar disorders would not be able function in various types of therapies.  Same with schizophrenic patients.  I would agree that from my limited experience that those who are under both psychiatric and psychological supervision do the best. That suggest the statement, "necessary to interlink the research into the biological, psychological and social factors, rather than reduce mental diseases to biological causes alone" is true and is already known in the community.

Part of the problem is that it easier to prescribe a pill than for the patient to got to weekly therapy sessions even if these sessions are readily available.

Also, the study does not deal with the severity of the illness.  An elderly patient who shows some signs of depression often is helped with a prescription since traditional talk therapy is difficult to arrange or be accepted by the patient.  When the sleep pattern is restored and person becomes more active during the day, the patient does better.  This is the place that the caregivers and family members can help the doctor to adjust the prescription.
necessary to interlink the research into the biological, psychological and social factors, rather than reduce mental diseases to biological causes alone" is really commonsense but the reality as shown in the article is that the availability of a psychologist or other therapist requires long wait for appointment.
