Background:
The Affect Intensity Measure (AIM) examines emotional reactions to typical life events. It typically contains 40 items, although a 20 item short-form of the measure is available, rated on six point scale from Never to Almost Always. The AIM gives an indication of how strongly or weakly an individual tends to experience emotions in their everyday life.
