Practise distinguishing inter-rater, inter-observer and test-retest reliability, then improving consistency and replicability through standardised procedures.
Dr Jones is conducting a case study of a man, Kevan, who has been practising mindfulness for 10 years.
Dr Jones has several different questions on his self-report that he has used repeatedly with a similar case. He has identified two problems:
- Problem 1: when he studies the responses to one item, he discovers that there are several different ways to interpret the answers.
- Problem 2: he is concerned that another item, which was supposed to measure mindfulness, is measuring happiness instead.
Explain which problem relates to reliability.
