Effectiveness = performance under ….conditions

A

34
Q

true or false:
In real-world effectiveness studies, testing pharmacological treatments is not different from testing psychotherapy

A

false
it is differentas there are many extraneous variables + confounds. But this kind of study gives us a more realistic depiction

35
Q

RCTs are known as what?

A

the Evidence Generator

36
Q

are blind studies possible for therapy

A

not always

37
Q

if u cant have a double blind study in RCTs, what can you do

A

Try to have groups as equal as possible

38
Q

true or false
in RCTs, we always Use same instrument/measure before and after

A

true

39
Q

in RCTs, what does TAU stand for

A

TAU = treatment as usual; might be effective/have an effect

40
Q

why should Control and treatment groups should have similar baseline measures

A

so you can compare changes

41
Q

in RCTs, why should sample sizes should be similar and large

A

to generalise

42
Q

fill in the blank
RCTs Want to compare size of baseline and … measures on control and
treatment groups, but also want to compare the size of the treatment’s and control’s
…measures

A

-post-intervention
-post-intervention

43
Q

what constitutes evidence

A

Evidence = empirical data; data gathered using the ‘scientific method’
○ Empirical = observable or verifiable through observation rather than theory

44
Q

read the following, and answer the questions that follow
“Those psychological interventions that have been shown by means of empirical
research to reduce symptomatology and increase functioning among clients, at a rate
that is beyond what would have occurred by chance” (Kagee & Lund, 2012, p.103)

Functioning according to whom?

A

Capitalist + Western ideas

45
Q

Symptoms are taken as universal facts. Give 2 reasons they may not be

A

■ Labelling + definitions are constructed
■ Symptoms constructed + viewed + experienced differently

46
Q

fill in the blank
there is an assumption of healing as…
Why might this not be the case?

A

linear

Eg in PDT, often feel worse before you feel better and you’re bringin stuff up (one of the reasons PDT stuggles to gain “evidence” support from RCTs)

47
Q

name 5 criteria of am EB Psychotherapy

A

○ Specific patient characteristics
- Use mutiple outcome measure
○ Random assignment
○ Using a manualised intervention
○ Statistically significant effect size
○ Outcomes can be replicated

SURUSO

*this is basically an RCT

48
Q

true or false
there are over 320 EB interventions

A

true
○ Not just therapy, might be at a hospital, with lay-counsellors, etc
○ Some to try develop efficacious + effective interventions (think task-sharing)

49
Q

why are the following criteria of EB Psychotherapies seen as unrealistic:
● Inclusion and exclusion criteria are clear
● NB to reduce in-group variability
● More than 1 diagnosis/problem often leads to exclusion

A

○ Intervention only shown to be effective for people with only that problem
(and no others)

50
Q

what does Randomising participants do

A

reduces bias

51
Q

what does having a control group do

A

allows for a suitable bias

52
Q

name 4 different types of control groups

A

○ No-treatment
○ Treatment as usual (TAU)
○ Attention as placebo
○ Waitlist

53
Q

what is a placebo effect in a control group

A

-> attend to them, but not giving them actual treatment

54
Q

what are the critiques of placebos in control groups

A

■ Hard to have “placebo” in psychotherapy
■ Ethics around telling someone they’re being treated when they’re not

55
Q

what is the critique of no-treatment as a control group

A

bar is too low (most therapies are effective)

56
Q

what is the critique of TAU as a control group

A

no standard for TAU in psychology (unlike medicine

57
Q

true or false:
Comparison studies often use under-trained therapists

A

true
■ May use different types of therapy (not really comparable)
■ May use trainees versus experts (not really comparing therapies, but
experience + expertise

58
Q

what does fidelity mean in terms of EBT

A

Fidelity = staying true to the intervention; everyone gets same treatment

59
Q

what are manualized interventions

A

● Consistency in application (fidelity) -> standardised, controlled

60
Q

give 3 advantages of Manualised Interventions

A

● Prevents drift -> giving different, non-manual advice
● Allows for replication (clear procedures)
● Allows for task-sharing

61
Q

true or false:
○ Manuals cant be obstacles to relating

A

false
-they can be.
- Over-focus on script rather than addressing issues that arise and following the patient

62
Q

fill in the blank
technique is … despite evidence for
non-specific factors

A

curative

63
Q

what assumptions do manual-based interventions incorrectly make

A

-Assumes one-approach fits all
- Based on assumptions of health

64
Q

what approach do most studies use to generate data

A

Most studies use many outcome measures
○ Interventions may show improvements on some outcomes but not others.

65
Q

complete the sentence
Outcomes measure variety of variables, which can generate a lot of ….

A

data

66
Q

in terms of Using Multiple Outcome Measures, what deems Slanted reporting of outcomes

A

Often, there is a mixed set of effects across the various measures, but researchers may only report on outcomes that show improvement, to provide evidence of the intervention’s success

67
Q

true or false:
there are specific guidelines regarding the selection of appropriate measures used to
assess outcomes

A

false
there are no guidelines, Not all measures are equally important, psychometrically sound or sensitive to change

68
Q

what does psychometric validity look at

A

Is the instrument valid (measure what it says it measures) and reliable (achieve the same result with repeated administration)?

69
Q

what are the following questions looking at
Is the change that is being measured important to participants’
lives?
Does it affect their functioning or daily living? Or does it measure some arbitrary construct that has no real bearing on patients’ lives?

A

importance and sensitivity to change in outcome measures

70
Q

Evidence relies on ‘significant’ outcomes -> how effective it has been
name two types of significance

A

● Statistical significance (change didn’t occur by chance) -> does not mean big difference
● Clinical significance (effect on functioning)
○ Statistical versus real-world, lived experiences

71
Q

what does the effect size look at (2 marks)

A

-size of the pre- and post-intervention difference
- amount of benefit

72
Q

name 3 critiques to statistical significance in EBT

A

○ Statistical significance has little bearing on functioning (i.e. clinical significance) (yet seen as evidence)
○ Also, improvement does not mean recovery/cure

73
Q

outcomes can be replicated by

A

● Repeating methods in other studies will produce (Following manuals faithfully will produce same outcomes)

74
Q

what is the critique of replicating outcomes (3 marks)

A

○ Assumes a ‘cookbook’ approach to therapy- If follow the ‘recipe’ and doesn’t work, then it’s the patient’s fault
○ One-size-fits-all approach
○ Assumptions about what it means to be mentally ‘healthy’

75
Q

complete the sentence
● ‘Evidence’ has come to only mean results from …

A

RCTs

76
Q

scientific evidence is known as what

A

the holy grail

77
Q

what is the problem with Specifying patient characteristics

A

○ Unrealistic and means treatments aren’t suitable for most people

78
Q

manuals reduce therapy to what two things

A

technique and strategy

79
Q

what does multiple outcomes imply

A

○ Evidence that doesn’t support the therapy can be excluded

80
Q

Statistical significance does not equal what?

A

real-world benefits or recovery

81
Q

what does the replication of outcomes imply

A

one-size-fits-all, highlights assumption of what it means to be healthy

82
Q

true or false:
> Claims about efficacy are misleading

A

true
The problem is not with the notion of evidence-based therapy but with how and by whom ‘evidence’ is defined.

Think About
● Ethics (fairness, inclusion/exclusion)
● Constructing and going about getting evidenc
