The Danish version of the Medication Adherence Report Scale: Preliminary Validation in Cancer Pain Patients

Objective:   To examine the psychometric properties of the Danish version of the Medication Adherence Report Scale (DMARS-4) adapted to measure adherence to analgesic regimen among cancer patients.
Methods:   The validated English version of the Medication Adherence Report Scale was translated into Danish following the repeated back-translation procedure. Cancer patients for the study were recruited from specialized pain management facilities. Thirty-three patients responded to the DMARS-4, the Danish Barriers Questionnaire II, The Danish version of Patient Perceived Involvement in Care Scale measuring the quality of patient-physician pain communication, and the Danish Brief Pain Inventory pain severity scale.
Results:   A factor analysis of the DMARS-4 resulted in one factor. Mean (SD) score on the cumulative scale ranging from 4 to 20, with higher scores indicating better medication adherence, was 17.8 (0.42). The DMARS-4 scores were related to the measures of patients' concerns about pain management and patients' pain communication. The internal consistency of the DMARS-4 was 0.70.
Conclusions:   The DMARS-4 seems to be a valid and reliable measure of self-reported adherence to analgesic regimen in the context of cancer pain.     

Relationship between pain-specific beliefs and adherence to analgesic regimens in Taiwanese cancer patients: a preliminary study

This pilot cross-sectional study aimed to 1) explore pain beliefs and adherence to prescribed analgesics in Taiwanese cancer patients, and 2) examine how selected pain beliefs, pain sensory characteristics, and demographic factors predict analgesic adherence. Pain beliefs were measured by the Chinese version of Pain and Opioid Analgesic Beliefs Scale-Cancer (POABS-CA) and the Survey of Pain Attitudes (SOPA). Analgesic adherence was measured by patient self-report of all prescribed pain medicine taken during the previous 7 days. Only 66.5% of hospitalized cancer patients with pain (n = 194) adhered to their analgesic regimen. Overall, patients had relatively high mean scores in beliefs about disability, medications, negative effects, and pain endurance, and low scores in control and emotion beliefs. Medication and control beliefs significantly predicted analgesic adherence. Patients with higher medication beliefs and lower control beliefs were more likely to be adherent. Findings support the importance of selected pain beliefs in patients' adherence to analgesics, suggesting that pain beliefs be assessed and integrated into pain management and patient education to enhance adherence.     

Barriers to Cancer Pain Management in Danish and Lithuanian Patients Treated in Pain and Palliative Care Units

The prevalence of cancer-related pain is high despite available guidelines for the effective assessment and management of that pain. Barriers to the use of opioid analgesics partially cause undertreatment of cancer pain. The aim of this study was to compare pain management outcomes and patient-related barriers to cancer pain management in patient samples from Denmark and Lithuania. Thirty-three Danish and 30 Lithuanian patients responded to, respectively, Danish and Lithuanian versions of the Brief Pain Inventory pain scale, the Barriers Questionnaire II, the Hospital Anxiety and Depression Scale, the Specific Questionnaire On Pain Communication, and the Medication Adherence Report Scale. Emotional distress and patient attitudes toward opioid analgesics in cancer patient samples from both countries explained pain management outcomes in the multivariate regression models. Pain relief and pain medication adherence were better in Denmark, and the country of origin significantly explained the difference in the regression models for these outcomes. In conclusion, interventions in emotional distress and patient attitudes toward opioid analgesics may result in better pain management outcomes generally, whereas poor adherence to pain medication and poor pain relief appear to be more country-specific problems.     

Barriers to the analgesic management of cancer pain: a comparison of attitudes of Taiwanese patients and their family caregivers

The purposes of this study were as follows: (1) to compare the attitudes which were considered to be barriers to cancer pain management held by Taiwanese cancer patients and their family caregivers; (2) to determine if these barriers were related to patient hesitancy to take analgesics and/or family caregiver hesitancy to administer analgesics: and (3) to determine if attitudinal barriers by patients and/or family caregivers predicted the adequacy of analgesics that patients used. A total of 159 dyads of oncology outpatients and their primary family caregivers (n = 318) participated in this study. The instruments completed by patients consisted of the Barriers Questionnaire-Taiwan form, the Brief Pain Inventory-Chinese version, the ECOG performance status scale, and a demographic and medication questionnaire. Family caregivers completed the Barriers Questionnaire-Taiwan form and a demographic questionnaire. The data in this study revealed that patients and family caregivers had attitudinal barriers to pain management and these concerns were positively correlated between patients and caregivers. Patient concerns were related to their hesitancy to take analgesics and, similarly, caregiver concerns were related to their hesitancy to administer analgesics. Most importantly, patient and caregiver concerns had an impact on how the patients' pain was managed: (1) patients and their family caregivers with higher levels of concerns used inadequate analgesics as compared to patients using adequate analgesics; (2) family caregiver barriers (concerns) were a significant predictor of inadequate management of cancer pain (after controlling for demographic and disease variables). Therefore, educational interventions for overcoming these barriers for both patients and their family caregivers may have potential for improving the management of cancer pain in Taiwan.     

Congruity of cancer pain perceptions between Taiwanese patients and family caregivers: relationship to patients' concerns about reporting pain and using analgesics

The purposes of this study were twofold: first, to examine the congruity of cancer pain perceptions between Taiwanese cancer patients and their family caregivers and second, to determine if there was a relationship between this congruity of perception and patients' concerns about reporting pain and using analgesics. A total of 89 dyads of oncology inpatients and their primary family caregivers participated in this study. The instruments completed by patients consisted of Barriers Questionnaire Taiwan Form, the Brief Pain Inventory Chinese version (BPI), the Eastern Cooperative Oncology Group (ECOG) performance status scale, and a demographic questionnaire. Family caregivers completed the Brief Pain Inventory short form and a demographic questionnaire. The Pearson's correlation, intraclass correlation coefficients, and the kappa statistics between family caregivers and patients' pain ratings were statistically significant. Patients in the noncongruent group (difference of >1 on "pain now" scale of the BPI) experienced higher levels of pain and poor levels of performance status. Family caregivers in the noncongruent group were more likely to be older and less educated. A patient's greater concerns about reporting pain and using analgesics were related to a lower level of congruity concerning pain perception between them and their family caregivers. Interventions aimed at overcoming patients' concerns about reporting pain and using analgesics may have beneficial effects on the congruency between pain perceptions of patients and family caregivers.     

Concerns about pain management among adolescents with cancer: developing the Adolescent Barriers Questionnaire.

Investigators have examined barriers to pain management in adults with cancer, but these patient-related barriers have rarely been studied in adolescents. This article summarizes 2 studies used in the development and initial psychometric testing of the Adolescent Barriers Questionnaire (ABQ). Building on the Barriers Questionnaire-II, the ABQ is designed to measure the extent to which adolescents with cancer have concerns about reporting pain and using analgesics. Study 1 was a qualitative study investigating pain management concerns of 5 adolescents with cancer. Concerns emerged that could potentially impede pain management such as fear of addiction and worry about communicating pain to parents and providers. Each of the adolescents revealed at least 1 concern about pain management or held fatalistic beliefs that cancer pain cannot be relieved. In study 2, content validity of the preliminary ABQ (52 items assessing 13 barrier sub-scales) was assessed by 2 panels, adolescents with cancer and clinicians. Based on results, the ABQ was modified to contain 45 items that assess 11 barriers. Further examination of barriers in adolescents with cancer is warranted.     

The Danish Barriers Questionnaire-II: Preliminary Validation in Cancer Pain Patients

Objective:   The objective of this study was to examine the psychometric properties of the Danish version of the Barriers Questionnaire-II (DBQ-II).
Methods:   The validated Norwegian version of the DBQ-II was translated into Danish. Cancer patients for the study were recruited from specialized pain management facilities. Thirty-three patients responded to the DBQ-II, Hospital Anxiety and Depression Scale, and Brief Pain Inventory pain severity scale.
Results:   A factor analysis of the DBQ-II resulted in six scales. Scale one, Fatalism, consisted of three items addressing fatalistic beliefs regarding cancer pain management. Scale two, Immune System, consisted of three items addressing the belief that pain medications harm the immune system. Scale three, Monitor, consisted of three items addressing the fear that pain medicine masks changes in one's body. Scale four, Communication, consisted of five items addressing the concern that reports of pain distract the physician from treating the cancer, and the belief that "good" patients do not complain. Scale five, Addiction, consisted of two items addressing the fear of becoming addicted to pain medication. Finally, scale six, Tolerance, consisted of three items addressing the fear of getting tolerant to analgesic effect of pain medicine. Items related to medication side effects were analyzed as separate units. The DBQ-II total had an internal consistency of 0.87. The DBQ-II total score was related to measures of pain relief and anxiety.
Conclusions:   The DBQ-II seems to be a reliable and valid measure of the barriers to pain management among Danish cancer patients.     

Identifying attitudinal barriers to family management of cancer pain in palliative care in Taiwan

The purpose of this study was threefold: (1) to examine attitudes held by Taiwanese family caregivers of hospice inpatients with cancer that serve as barriers to cancer pain management; (2) to determine the relationship of attitudinal barriers to family caregiver hesitancy to report pain and to administer analgesics; and (3) to determine the relationship of attitudinal barriers to the adequacy of analgesics used by the patient. A total of 80 pairs of palliative care inpatients and their primary family caregivers participated in this study. Family caregivers completed the Barriers Questionnaire-Taiwan (BQT) form and a demographic questionnaire. The instruments completed by patients consisted of the Brief Pain Inventory-Chinese version and a demographic questionnaire. The data revealed that Taiwanese family caregivers of palliative care patients with advanced cancer had concerns about reporting pain and administering analgesics, particularly as they related to disease progression, side-effects and p.r.n. analgesics. Older and less-educated family caregivers scored significantly higher on the BQT than did their younger, more educated counterparts. Family caregivers' concerns measured by the BQT were related to family caregivers' reluctance to administer analgesics to their patients. Implications for a broader understanding of analgesics in the advancement of pain management in palliative care in Taiwan are discussed.
