A few thoughts on conducting test-retest reliability analysis on questionnaires, based on my own recent experiences.
DO:
- pay attention to your coding sheet before doing the test, it will influence your questionnaire design
- make sure you pilot your questionnaire for ambiguity and understanding before doing the test, it may not be essential but it is logical
- capture the data yourself, it will give you insight and a deeper appreciation of the process
- make sure you have a way to uniquely identify each questionnaire, and simple codes are better than complex ones
- make sure you ask participants to uniquely identify each form they complete, but make sure to preserve anonymity
DO NOT:
- rely on handwriting recognition to achieve the last point if you forgot to do it, it will waste your time and take you into a valley of despair
- rush the process, you will make mistakes if you do
