Mark scheme

Marking points from the official mark scheme (May/June 2020). The mark or mark type is shown in brackets.

  1. [2] Gathering baseline data at the outset of a programme allows a comparison with data gathered afterward, allowing changes to be tracked to determine whether any intervention has been effective.
  2. [2] Participants may drop out over the 9 months of therapy and 9 months of follow-up
  3. [2] Over time, participants may not follow the treatment programme exactly; may take other medications; may develop other symptoms and/or illnesses.
  4. [1] 'manualized cognitive behavioural therapy developed particularly for schizophrenia with that of a nonspecific befriending control intervention.'
  5. [2] Researchers do not allocate participants to conditions so there is no bias. Instead participants are allocated randomly, by chance, so reducing extraneous variables. Use of control group etc.
  6. [1] no drugs are taken
  7. [1] the patient does not become addicted to drugs
  8. [1] the patient plays a more active role in their own treatment
  9. [1] a therapist is there to guide the patient through the treatment
  10. [1] more effort is needed by the patient; it isn't passive as is taking a drug
  11. [1] the cause of schizophrenia may be biochemical and so a drug treatment may be best
  12. [1] a therapist is needed, which costs more and consumes more time than does swallowing a pill
  13. [1] any appropriate conclusion drawn from the discussion that has been presented.
