The QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item scales and single-item measures. These include five functional scales (physical, role, emotional, social, and cognitive), three symptom scales (fatigue, nausea and vomiting, and pain), a global health status / QoL scale (GHS/QoL), and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and difficulties). Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." The principle for scoring these scales is the same in all cases: 1. Estimate the average of the items that contribute to the scale; this is the raw score. 2. Use a linear transformation to standardize the raw score, so that scores range from 0 to 100; a higher score represents a higher ("better") level of functioning, or a higher ("worse") level of symptoms. A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.
