The combination of both the thentest and the structural equation modeling approaches proved to be essential for obtaining comprehensive statistical evidence that response shift can distort measurements of change. Our results suggest that studies that use the thentest to evaluate the effectiveness of interventions should complement their analyses with the structural equation modeling approach to avoid biased effects.
