WHEN MIGHT YOU WANT TO CHECK THE RELIABILITY OF A MEASURE? EXAMPLE 1: You want to measure something in your sample, but you have not been able to find an existing standardised or usable instrument (questionnaire, test) to measure it with. You have therefore had to create a questionnaire but you are not sure if it is reliable. EXAMPLE 2: You have had to adapt an existing measure that was developed for adults, so that it can be used with your sample of children. You are not sure if your adapted version of the measure will be as reliable as the original version. EXAMPLE 3: You have devised a coding scheme for material gathered from semi-structured interviews with 12 parents of children with epilepsy, and you want to check how reliable your coding scheme is.
