Gallup-Healthways Life Evaluation Index
The Life Evaluation Index, one of six sub-components of the Gallup-Healthways Well-Being Index, includes a self-evaluation of two items (present life situation and anticipated life situation five years from now) using the Cantril Self-Anchoring Striving Scale with steps from 0 to 10, where "0" represents the worst possible life an "10" represents the best possible life. Taken together, respondents are then classified as "thriving," "struggling," or "suffering," with “thriving” respondents evaluating their current state as a “7” or higher and their future state as a “8” or higher, while “suffering” respondents provide a “4” or lower to both evaluations.
