CompositionThe questionnaire consists out of 18 (6 x 3) items that can be scored from “”Not at all = 0 to “Extremely = 4”. There are no mirrored items. The total score is an indication for the severity of complaints.
SubscalesBesides the total score, there are 3 subscales:

• Community norms (males/females/males and females combined)
• Oncology norms (males/females/males and females combined)
