In the literature, there are general cancer scales developed to evaluate the quality of life of head and neck cancer patients and sub scales associated with head and neck cancers developed in addition to these scales. In addition, scales specific to head and neck cancers have also been developed. However, previous research shows that even general health status scales or cancer-specific scales cannot determine outcomes related to many head and neck cancer patients. In addition, items containing multiple functions and patients' attitudes (behaviors) cannot be analyzed separately in any of the scales specific to head and neck cancer. Very few surveys contain items related to patients' attitudes (behaviors), or the number of items related to this topic is small because most of these scales are functional items. Unlike its counterparts in the literature, Head and Neck Cancer Inventory evaluates the attitudes (behaviors) of patients associated with various functions in daily life. Head and Neck Cancer Inventory is the only scale in the literature that contains the basic features of the health conditions declared by the patient and has been developed specifically for head and neck cancer.
