empirical

Explanation:

According to my research on the different methods of test construction, I can say that based on the information provided within the question you are using an empirical method. This approach is based on statistical analysis of data gathered from a series of test items, in which the items are stored, and then the data gathered is examined for similarities or patterns between different responses answered by the groups of people. Which is why you decided to keep the fifteen items that the depressed and non-depressed groups answered differently.
