Motivation and Energy Inventory (MEI)
The MEI is a 27-item scale created to assess fatigue and lassitude. The scale was initially developed for the purpose of evaluating interventions to improve motivation and energy in patients with depression, though with further evaluation, its clinical applications could be extended to other patient groups . The MEI assesses three factors: mental or cognitive energy, social motivation, and physical energy.
