Step 2: Run a Pilot Test Select a subset of your intended survey participants and run a pilot test of the survey.
These are known as factor loadings, and questions point back to the same elements should load into the same factors. Solid values to look for are factor loadings of 0.6 or above.
You’ll occasionally run across questions that don’t appear to load onto any factors, which may necessitate a question removal or separate analysis.
Like PCA, CA can be complex and most effectively completed with help from an expert in the field of survey analysis.
Step 6: Revise Your Survey The final stage of the validation process is to revise your survey based on the information you gathered from your principal components analysis and Cronbach’s Alpha.

The more participants you can round up, the better, although even a smaller sample can help you weed out irrelevant or weak questions.
Because there are multiple, tough-to-control factors that can influence the dependability of a question, validating a survey is neither a quick nor easy task.
How to Do It Collingridge outlines a six-step validation method he has successfully used over the years.The number of factor-themes you can identify indicates the number of elements your survey is measuring.
