CBT- Evaluation Flashcards
1 Strength (Research Support)
Kuiper et al: Conducted first major study in this area
60 ind w schz- suffer w pos and distressing smptoms and are medicant resistant
Randomly allocated ppts to CBT + standard care/ standard care only coniditons
CBT + SC = 50% improved
Sc= 31%
1 Weakness: (Contradictory Evidence)
Jahuar et al suggested only a small therapeutic effect of using CBT on patients w schz
H/o- month later; Morrison et al reported that CBT significant reduced psychotic symptoms in ind w schz
Lack of consistent findings reduces the reliability of research in this area, t/f a key weakness
1 Strength: Scientific
CBT= Scientific
Uses structured, testable methods like thought diaries that can be measured and evaluated using a symptom rating scale (PANSS)
S because it is supported by large amounts of empirical research and clinical studies
1 Weakness: Short term studies
Appears to be limited to short term studies.
Research focused on long term studies has not published such positive results.
Tarrier et al: compared outcomes of ind w schiz that receieved standard care or CBT after 18 months.
Relapse rates were the same for both
W bc- suggests that the effects of treatment are short lived
1 Strength: Ethical
1 S: May have pos ethical implications
Suffering w symptoms of schz, being diagnosed and then being put on strong sedative meds is a scary and potentially harmful experience for ind w schz
Kuiper et al; reported clients were generally satisfied after CBT and felt it was appropriate
S bc; reviewing a therapy from a clients perspective is important for assessing its value and ethical impact
1 Weakness (ethical)
1 W: potential risk of psych harm
CBT= involves challenging a patients held beliefs. For ind w schz, this may include questioning hall/del which can be distressing.
If the therapist pushes too hard, this can lead to the individual feeling overwhelmed and disengage from the therapy.
W bc; risk of anxiety, stress humiliation and pain
1 Strength: (social)
1S: May reduce costs for society
Kuiper et al: analysed the economic impact of offering CBT alongside antipsychotics. Found that although CBT may be more costly in the short-term, it may reduce long-term costs due to reducing relapse rates and decreasing the usage of emergency psychiatric services.
S Bc: May be a cost effective treatment
1 Weakness (social)
1 w : may not be available for all
In the national audit of schizophrenia there are variations across trusts in relation to the number of people being offered CBT - 50% report not being offered CBT
W bc: it contradicts the NICE guidelines which reccomend that any adult w schz should be offered CBT
