Answer 1

Consistency

Question 2

How do we no if a study is reliable

Answer 2

If similar results are obtained when the study is replicated

Question 3

Answer 3

Using a standardised procedure

Question 4

How can we assess reliability in observations

Answer 4

• Inter - observer reliability
• which can be assessed by ensuring the extent to which different observers, scoring same ptps achive consistency
• strong positive correlation of 0.8 or more suggest good inter - rater reliability

Question 5

What can make independant checks for reliability easier

Answer 5

Using audio tape and video tapes

Question 6

Hw to improve low inter rater reliability

Answer 6

• training observers to us behavioural categories so they respond quickly
• operationalising terms precisely ( categories clear) so all observer categories behaviours the same way

Question 7

How to asses reliability of self report techniques

- method involves presenting the same pts with the sae test on different occasions
- strong positive correlation between the test and retest scores indicates reliability
