How Sparse Is Too Sparse?

Research Methods Track

Clients often want to test many items using MaxDiff. Previous research shows that Sparse MaxDiff is a valid technique for testing these conditions; however, these designs typically include many alternatives per task (5 or more). What happens when the items are extremely wordy or long? With triplets or, even worse, paired comparisons, we get much less information per task - can Sparse approaches still work under these more extreme conditions?
