Advantages of Psychological Therapies

Even though psychological treatments can't cure schizophrenia, they have been successful in making schizophrenia more manageable and improving quality of life for patients.

Pros of token economies

  • Token economies help by making patients behaviour more socially acceptable so that they can better reintegrate into society.

Disadvantages of Psychological Therapies

Evidence supporting the effectiveness of psychological treatment for schizophrenia is modest at best. Schizophrenia remains one of the hardest mental health conditions to treat.

Weakness - lack of cure

  • The failure of psychological treatments to actually cure schizophrenia is a major weakness.

Ethical concerns with CBT

  • There are ethical issues related to psychological treatments for schizophrenia (even though there's an absence of side-effects or medical risk associated with drug treatments.)
  • CBT might raise ethical concerns because it can be seen to be interfering with a person’s freedom of thought. If a patient is encouraged to challenge their paranoia of a controlling government, this might lead to change in their entire political outlook.

Ethical concerns with token economies

  • A major ethical consideration with token economies is that privileges become more available to patients with less severe symptoms because compliance is lower amongst those with more severe symptoms.
  • This results in discrimination against very ill patients, leading to some families challenging the legality of the system.

Quality of the evidence

  • The quality and effectiveness of psychological treatments has been challenged.
  • Studies often lack control groups and participants are rarely randomly allocated to conditions.
  • These methodologically weak studies tend to be more optimistic in their results and conclusions than studies employing tighter controls.

Lack of availability - art therapy

  • There is some concern that therapies that might help some patients aren’t widely available.
  • For example, The National Institute for Health and Clinical Excellence (NICE) recommends art therapy, provided by a qualified art therapist with experience of working with schizophrenia sufferers, is made more widely available.
