To create a total score, sum the scores across the 33 items.
The CHIPS is a list if 33 common physical symptoms. Items
were carefully selected so as to exclude symptoms of an obviously
psychological nature (e.g., felt nervous or depressed).
The scale does, however, include many physical symptoms that have
been traditionally viewed as psychosomatic (e.g., headache, weight
loss). Each item is rated for how much that problem bothered
or distressed the individual during the past two weeks.
Items are rated on a 5-point scale from "not at all"
