- Test-retest

- A
strong positive correlation using Spearman's rho or Pearson's r between the scores indicates good reliability
- A correlation coefficient of +0.80 indicates high reliability
- A
strong positive correlation using Spearman's rho or Pearson's r between the scores indicates good reliability
- The study/analysis/questionnaire is repeated several times under the same conditions at different times
- Inter-observer
- More
than one researcher carries out the observation/analysis, indpendently.
- Strong
positive correlation using Spearman's rho or Pearson's r between their scores means good reliability
- A correlation coefficient of +0.80 indicates high reliability
- A pilot study should be conducted to ensure that the observers are applying the behavioural categories in the same way.
