If your questionnaire contains a scale, download this Excel program to evaluate the reliability and construct validity of that scale. To use this Excel program, you should have (1) given several participants your questionnaire, (2) calculated a score for each participant that is the sum of the participant's responses to the odd-numbered questions (1, 3, 5, etc.) that make up your scale (for this sum, ignore survey questions that are not part of the scale), and (3) a score for each participant that is the sum of the participant's questions to the even-numbered questions (2,4, 6, etc.) on your scale (again, don't include survey questions that are not part of your scale ). Although not necessary, It would also be helpful if you had a score for each participant on another related measure. |
