Frisch’s QOLT uses a four-path model to increase life satisfaction and happiness. The rubric of this model is CASIO, which stands for:
(C) circumstances or characteristics of an area of life,
(A) a person’s attitude with respect to that area,
(S) a person’s evaluation of fulfillment in an area, based on the application of standards of achievement,
(I) the value or importance a person gives to an area for overall happiness or well-being, and
(O) overall satisfaction in areas of life that are not of immediate concern.
