SAVAGE AND ARMSTRONG (EVALUATION)

Question 1

Can you name 2 strengths of the study?

Answer 1

• Feild experiment.
• Reliability.

Question 2

Can you name 2 weaknesses of the study?

Answer 2

• Generalisbilty.
• Validity and subjectivity

Question 3

One strength of the study was the use of a field experiment…

Answer 3

• POINT: ….Significantly increases the ecological validity.
• EVIDENCE: Conducted in a GP surgery with actual patients.
• EXPLANATION: Behaviours and satisfaction levels recorded are more likely to reflect true patient experiences (genelisable)

Question 4

Another strength of the study is that it is high in reliability….

Answer 4

• POINT: Due to the use of standardisation.
• EVIDENCE: The same DR was used for all consultations, standardised prompts.
• EXPLANATION: Maintains the uniformity in the consultation approach. Controls for variability in the DR’s behaviour/approach minimising EV

Extraneous variable

Question 5

One weakness of the study was the low generalisability…

Answer 5

• EVIDENCE: Conducted with a single DR in a specific GP surgery//Ppts were all from the same geographic area.
• EXPLANATION: Limiting the variety of DR-patient interactions observed, lowers applicability to real-world clinical settings

// they may have similar characteristics, thus unrepresentative/ genralisable to diff populations/settings

Question 6

Another weaknesses of the study was the use of a questionnaire as the primary data collection method which lowers the validity due to…

Answer 6

• POINT: Subjectivity of the data.
• EVIDENCE: Questionnaire was designed to measure subjective satisfaction levels.
• EXPLANATION: Can be affected by other variables (unrelated individual expectations, prior medical experinces)

Question 7

Why does the fact the study was a feild experiment increase ecological validity/ generalisability?

Answer 7

Behaviours and satisfaction levels recorded are more likely to reflect true patient experiences (genelisable)
