- Improving Reliability
- Experiments
- standardised procedures, standardised instructions; environment kept as constant as possible
- Operationalise variables
- Pilot test – to identify any problems
- Observations
- Behavioural Categories fully operationalise
- Train observers and discuss so that observers are clear about how to interpret behaviour
- Questionnaire
- Questions might need to be re-written if they are too complex or ambiguous
- Use more closed questions, leaves less room for (mis)interpretation.
- Interviews
- Use the same interviewer each time
- Train interviewers carefully to ensure questions are asked in the same way
- Use structured interviews, so the interviewer's behaviour is controlled by the fixed Q's.
- Content Analysis
- Categories carefully operationalised
- Have more than one rater to carry out the analysis independently from each other.
- Train raters in the correct interpretation and use of coding units.
- Experiments
