Q

Why do some clinicians argue against training in pure science?

A

Applied work is often incompatible with scientific work and some research doesn’t apply to practice.

Q

Under the Practitioner-Scholar model, what is the model of a clinician working scientifically? (List 4 things)

A
  1. Applied scientist who uses theory and validated principles of assessment and validated treatments (where they exist)
  2. If they don’t exist, apply scientific methods and principles of observation, hypothesis generation with testing applied in individual cases and client groups
  3. Duty to pursue ideas derived from psychological science to improve upon existing assessment/treatments, develop new procedures and investigation the nature of clinical problems that bring people to the clinic
  4. This ensures that public money is spent on procedures justified by the current state of knowledge

26
Q

What are the 5 A’s in EBP?

A
  1. Ask the right questions (PICO)
  2. Access relevant evidence
  3. Appraise evidence
  4. Apply evidence
  5. Assess its effectiveness
27
Q

Why do you need to formulate a focused, well built, answerable question? (3 reasons)

A
  1. Gives you a head start in finding information that is relevant
  2. Provides you with a checklist for the main concepts to be included in your search strategy
  3. Allows you to find information quickly.
28
Q

What does PICO stand for?

A

P-Population/patient

I -Intervention

C-Comparison

O-Outcome

29
Q

What are 3 considerations when identifying the population/patient problem? (P in PICO)

A
  1. Who/what is the client/problem
  2. What are the most important characteristics of the client/problem
  3. What is the primary problem, disease or co-existing condition
30
Q

An example of P in PICO

A

In patients with binge eating disorders…

31
Q

What 2 considerations for interventions? (I in PICO)

A
  1. What is the main intervention you are considering?

2. What do you want to do for the client? Offer therapeutic intervention or teach a skill?

32
Q

What are the interventions you might consider?

A

Medication
Placebo
Counselling
Diagnostic tests
Provision of differing environmental factors
Methods of education (best way to share information with the client)

33
Q

What is an example of intervention (I in PICO)?

A

Interpersonal skills

34
Q

What are 2 condor Comparison (C in PICO)

A
  1. What is the main alternative to compare with the intervention?
  2. Are you trying to decide between two therapies, therapy and placebo or two diagnostic tests?
35
Q

Example of comparison in PICO

A

Or cognitive behavioural therapy

36
Q

List 2 considerations for outcome (O in PICO)

A
  1. What are you hoping to accomplish, measure, improve or change?
  2. What are you trying to do for the client? Relieve or eliminate the symptoms? Improve function or test scores? Improve a work environment?
37
Q

Example of outcome in PICO

A

…more effective in reducing frequency of episodes.

38
Q

Example of PICO question

A

In patients with binge eating disorder, is interpersonal therapy or cognitive behavioural therapy more effective in reducing the frequency of binge eating episodes?

Population- people with binge eating disorder

Intervention- interpersonal therapy

Comparison- cognitive behavioural therapy

Outcome- reducing frequency of binge eating episodes

39
Q

What is the Cochrane Library databases?

A

The Cochrane Library is a collection of evidence based medicine databases including:

The Cochrane Database of Systematic reviews

The Cochrane Database of abstracts of reviews of effects

The Cochrane Central register of controlled trials

The Cochrane methodology register

Health technology assessment database

NHS economic evaluation database

40
Q

What is a review?

A

A collection of systematically generated articles which investigates particular areas of psychology. An executive summary of articles

41
Q

What do Cochrane reviews adhere to?

A

A strict process, minimising bias and ensuing reliability

42
Q

What is Hierarchy of evidence?

A

A core principle of EBP with hierarchy based on the rigours (strength and precision) of research methods. Study design is an indication of quality

It’s a top down approach to looking at the best evidence

Higher in the hierarchy, the less bias there is in interpretation of study results

43
Q

What is the highest form of research in the hierarchy of evidence?

A

Systemic reviews/meta-analysis

44
Q

What are systemic reviews and meta-analysis?

A

Thorough analysis of results, strength and weaknesses of studies collated to address a particular PICO question

45
Q

What does meta-analysis involve?

A

A statistical evaluation of all relevant studies

DV is effect Size (outcome or results of each study)

IV relates to study characteristics (participants interventions and outcome measures)

But takes a long time to put together and information can change

46
Q

What are some limitations of systematic reviews and meta-analysis?

A

Takes a long time to complete and information changes fast

A large well controlled RTC may provide more convincing evidence than a systematic review of smaller studies

47
Q

What is a Randomised Control Trial?

A

Experimental study where participants are randomly assigned to receive one of several (at least 2) interventions with a control/placebo/waitlist condition

48
Q

What is the purpose of an RCT?

A
  1. Eliminates bias in treatment assignment

2. Facilitates blinding of treatment to investigators

49
Q

What are the 5 disadvantages of an RCT?

A
  1. Requires rigorous control of the allocation process
  2. Can be long and expensive
  3. May not be ideal for rare conditions or problems with a long latency
  4. Generalisability (often screens out vulnerable groups)
  5. Ethics (withholding treatment in control)
50
Q

What are case control studies?

A

Allows you to determine whether exposure to something is linked to an outcome. Using existing records to identify people with a problem.

Eg comparing people with lung cancer to people without to see if they differ on a risk factor such as smoking

Starts with outcome and traces back to exposure

51
Q

What are case control studies useful for?

A

Investigating outbreaks of a disease and rare diseases

52
Q

What are the advantages of case control studies?

A

Quick simple inexpensive

53
Q

What are the disadvantages of case control studies?

A

Proves an association not causality and weaker because retrospective

54
Q

What are cohort studies?

A

A group of people who are linked in some way and followed over time. Researchers observe what’s happened to the group exposed to the same variable

55
Q

What are cohort studies used for?

A

Determining if there is a relationship between a certain factor and disease/outcome

56
Q

Are cohort studies retrospective or prospective?

A

Can be both

57
Q

What question is addressed if the aim of the study was to simply describe a study population?

A

PO questions (population/outcome

58
Q

What question was used if the aim of the study was to quantify relationship between factors?

A

PICO

59
Q

What kind of studies are randomly allocated?

A

Experimental/RCT

60
Q

What kind of studies are not randomly allocated?

A

Observational studies

61
Q

If the outcome is determined after exposure, what kind of study is it?

A

Cohort (prospective) study

62
Q

If outcome was determined at the same time as the intervention or exposure, what kind of study was it?

A

Cross sectional study

63
Q

If the outcome was determined before exposure was, what kind of study was it?
