The Association Between Analgesic Treatment Beliefs and Electronically Monitored Adherence for Cancer Pain

OBJECTIVES: To determine whether clusters based on analgesic treatment beliefs among patients with cancer predict objective analgesic adherence. SAMPLE & SETTING: 207 patients with cancer in the outpatient setting who were aged 18 years or older, self-identified as White or African American, were diagnosed with solid tumor or multiple myeloma, and were prescribed at least one around-the-clock analgesic prescription for reported cancer pain. METHODS & VARIABLES: This study is a secondary analysis of an existing dataset. General linear modeling with a backward elimination approach was applied to determine whether previously identified analgesic treatment belief clusters, as well as sociodemographic, clinical, and pain variables, were associated with adherence behaviors. RESULTS: Significant explanatory factors were experiential in nature and included sociodemographic, clinical, and pain-related variables, explaining 21% of the variance in analgesic adherence. Analgesic belief clusters were not predictive of adherence. IMPLICATIONS FOR NURSING: Future research should examine sociodemographic and other clinical factors, as well as the influence of analgesic treatment beliefs, to better understand adherence behaviors among patients with cancer.
