Thomas Homes and Richard Rehe set out to determine what events in people’s lives were most stressful. Surveying thousands of individuals, they created a list of circumstances that represent typical life stressors, or event that require some adaptation or readjustment to a situation. Their list, with a total of 43 events, included severallife event that, on the surface, appear to be positive, such as vacations, weddings, and outstanding personal achievement, as well as traumatic ordeals such as the death of a child. Then they devised a system to weigh each event according to its stress potential. All events were assigned numerical values based on their degree of disruption of one’s life and readjustment following the event. These values were called Life-Change Unit, or LCUs (Seaward, Brian Luke, 2009)
