Snyder proposed a "Hope Scale" which considered that a person's determination to achieve their goal is their measured hope. Snyder differentiates between adult-measured hope and child-measured hope. The Adult Hope Scale by Snyder contains 12 questions; 4 measuring 'pathways thinking', 4 measuring 'agency thinking', and 4 that are simply fillers. Each subject responds to each question using an 8-point scale. Fibel and Hale measure hope by combining Snyder's Hope Scale with their own Generalized Expectancy for Success Scale (GESS) to empirically measure hope. Snyder regarded that psychotherapy can help focus attention on one's goals, drawing on tacit knowledge of how to reach them. Similarly, there is an "outlook" and a "grasp of reality" to hope, distinguishing No Hope, Lost Hope, False Hope and Real Hope, which differ in terms of viewpoint and realism.
