Description:  The Quality of Life Scale (CASP-19) uses four domains (i.e., control, autonomy, pleasure and self-realization) to assess the quality of life in individuals in early old age.

Number of items: 19, including 6 items for control, 5 items for autonomy, 4 items for pleasure and 4 items for self-realization.

Example of statement/item: “I look forward to each day”

Response options: 4-point Likert scale ranging from 0, “never” to 3, “often”.

Total score: Items are summed, yielding a range from 0 to 57 for the total score (domains are usually not used separately). Higher scores indicate higher levels of satisfaction of quality of life.
