The blindfolding procedure is a sample reuse technique that omits part of the data matrix to assess a model's out-of-sample predictive power for specific endogenous constructs. The resulting Q² value (Stone-Geisser's criterion) must be above zero to confirm predictive relevance. Typically, Q² > 0.02, > 0.15, and > 0.35 indicate small, medium, and large predictive relevance, respectively. Â
