This study is the first to validate the MMAM for assessing adherence to analgesic regimens in patients with cancer pain. We have demonstrated that this measure has good psychometric properties for measuring compliance with analgesics regimens in Taiwanese cancer pain patients. Its reliability was supported by good internal consistency Cronbach α and fair test–retest coefficients. The measure's validity was supported by good known-group validity, construct validity, and criterion-related validity. Patients with hesitancy to take analgesics in the past week reported lower levels of adherence with analgesic regimens. The medication adherence scores correlated well with the analgesics ratio for medication actually used by the patient, indicating criterion-related validity. Medication adherence scores correlated well with the BQT scores for patients and family members, indicating convergent validity. The psychometric properties of the Taiwanese version of the MMAM are consistent with the original version used in populations in Western countries; it is the first instrument measuring adherence to analgesics regimens that was developed for Taiwanese cancer patients and shows excellent reliability and validity.

N2 - The purposes of this study were (1) to examine the psychometric properties of the Taiwanese version of the Morisky Medication Adherence Measure (MMAM), including its validity and reliability, (2) to investigate levels of analgesic regimen adherence, and (3) to explore the predictors of adherence to the analgesic regimen in a sample of Taiwanese cancer patients with pain. One hundred thirty-five patients receiving analgesics for cancer pain participated in this study. Instruments consisted of the Taiwanese version of the MMAM, the Barriers Questionnaire-Taiwan form, the Chinese version of the Brief Pain Inventory, the American Pain Society Outcome Questionnaire, Karnofsky Performance Status, and a demographic questionnaire. Analgesic use ratios were calculated. The Taiwanese version of the MMAM had good psychometric properties for measuring adherence with the analgesic regimens taken by Taiwanese cancer pain patients. Reliability was supported by good internal consistency Cronbach α and test-retest coefficients. Validity was corroborated by good known group validity, construct validity, and criterion-related validity. The majority of the patients (51%) showed low levels of medication adherence. The significant predictors for the medication adherence score were age, the Barriers Questionnaire score, and satisfaction with pain management by clinicians after entering pain severity, pain interference with daily life, age, gender, education, types of analgesics used, functional status, and satisfaction with pain management as independent variables. The model accounted for 63% of the variance in the medication adherence score. The Taiwanese version of the MMAM shows excellent reliability and validity. The use of this reliable, valid, simple, and easily administered tool can improve communication between patients and clinicians about use of analgesics and further improve the analgesic regimen adherence.
