ABSTRACT

PURPOSE: Head and neck cancer (HNC) and its treatment are associated with significant symptom burden and functional impairment. HNC patients must engage in intensive and complex self-management protocols to minimize acute and late treatment effects. Self-management among HNC patients is understudied due to the limited availability of disease-specific self-management measures. This article describes the initial psychometric testing of the HNC Patient Self-Management Inventory (HNC-PSMI), an instrument that characterizes self-management tasks in the HNC population.

METHOD: A cross-sectional survey design was used. One hundred HNC patients completed the HNC-PSMI, the Vanderbilt Head and Neck Cancer Symptom Survey plus General Symptom Survey, and the Profile of Mood States-Short Form. To evaluate the psychometric properties of the HNC-PSMI, the relevance of items, internal consistency of domain item responses, and the direction and strength of associations between domain scores and other measures were examined.

RESULTS: There was variability both in the number of self-management tasks performed overall and in each domain as well as in the reported difficulty completing those tasks. Kuder-Richardson values for domains with >3 items ranged from 0.61 to 0.86. Hypothesized associations were supported.

CONCLUSIONS: Overall, the psychometric properties for the HNC-PSMI were acceptable. The HNC-PSMI can be used to advance an understanding of self-management requirements and challenges in HNC patients.
