Athletic Motivation Inventory

The Athletic Motivation Inventory was developed in 1969 by Thomas Tuko, Bruce Ogilvie, and Leland Lyon. It has just under 200 questions and measures the following scales:
 * Drive
 * Aggression
 * Determination
 * Responsibility
 * Leadership
 * Self-confidence
 * Emotional control
 * Mental toughness
 * Coachability
 * Conscience
 * Trust

There are doubts about its usefulness.
