Kart A review article which concluded that CBT is an effective therapy, particularly in treating the positive symptoms of schizophrenia

Question 10

what are some limitations of CBT

Question 12

what is some supporting evidence for the use of family therapies

Answer 12

pharoah compared antipsychotics with family therapy
those who underwent family therapy are more likely to be more consistent with there medication
less likely to relapse
however, only in some pts did this improve symptoms of Sz

Question 13

who found some more supporting evidence for family therapies

Answer 13

lobban analysed the results of 50 family therapy studies and found that 60% of studies reported a significant positive outcome.

Question 14

what are some economic implication of family therapies

Answer 14

NICE-found that family therapies are more likely to take there medication so less likely to relapse so wont go back to hospital so reduced number of SZ pateints to look after

Question 15

how do you manage patients symptoms in Sz

Answer 15

Patients are given reward tokens when they engage in positive, adaptive behaviour.
Tokens can be exchanged for rewards.
The patient learns to repeat positive, adaptive behaviours through positive reinforcement.
they are used to manage the patients behaviour

Question 16

what is some supporting evidence for the use of tokens in Sz

Answer 16

Dickerson conducted a review of 13 studies and found that 11 reported that their was beneficial effects of the use of token economies
however, there was no control group so we cant establish cause and effect relationships

Question 17

what are some strengths of token economies

Answer 17

Token economies may be useful for patients whose symptoms are mild and who need some motivation to enable them to cope with everyday challenges such as social interaction and personal hygiene
A programme of token economy behaviour management is less potentially harmful than drug therapy so it may be more ethically valid to some extent

Question 18

what are some weaknesses of token economies

Answer 18

may not be useful outside a hospital setting as people with Sz arent consistency monitored
-positive behaviour cant be immediately rewarded so they are less likely to form an association

kazdin found that the effectiveness may be influence by the amounts of time between behaviour and being presented with the token
may be considered unethical-participants are treated as children which is humiliating and may cause distress
-participants may become over-dependant on rewards which have negative effects once they leave
