  • Assessing Reliability
    • Test-retest
      • The study/analysis/questionnaire is repeated several times under the same conditions at different times
        • 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
    • 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.
