Quality of life is an important indicator for evaluating the outcome of treatment for patients with cancer pain. Perceived self-efficacy has been reported to play an important role in controlling quality of life (QOL). Limited studies have focused on opioid-taking self-efficacy effects on the patients' QOL, which is caused by cancer pain. The purpose of this study was to evaluate how much of the variance in QOL among Taiwanese cancer patients with pain could be accounted for by opioid-taking self-efficacy.
This cross-sectional study included 109 cancer patients who had taken prescribed opioid analgesics for cancer-related pain in the past week and completed the Opioid-Taking sSelf-Efficacy Scale and European Organization for Research and Treatment of Cancer Quality of Life Group Questionnaire.
There was a significant correlation between scores on self-efficacy total scale and functional QOL (r = 0.30, p < 0.01) and symptomatic QOL (r = -0.22, p < 0.05). The opioid-taking self-efficacy total scale accounted for 8% (R (2) = 0.08, p < 0.01) of the variance in predicting the patients' functional QOL and 7% (R (2) = 0.07, p < 0.01) of the variance in predicting the patients' symptomatic QOL.
This study highlights the potential importance of a patient's opioid-taking self-efficacy beliefs in their quality of life, which is relevant to cancer pain.
生活质量是评估癌症疼痛患者治疗效果的重要指标。据报道，自我效能感在控制生活质量（QOL）方面发挥着重要作用。针对癌症疼痛患者服用阿片类药物的自我效能感对其生活质量影响的研究较少。本研究旨在评估台湾癌症疼痛患者的生活质量差异中有多少可由服用阿片类药物的自我效能感来解释。
这项横断面研究纳入了109名在过去一周内服用过处方阿片类镇痛药以缓解癌症相关疼痛的癌症患者，他们完成了服用阿片类药物自我效能量表和欧洲癌症研究与治疗组织生活质量问卷。
自我效能感总量表得分与功能生活质量（r = 0.30，p < 0.01）和症状性生活质量（r = -0.22，p < 0.05）之间存在显著相关性。服用阿片类药物自我效能感总量表在预测患者功能生活质量的方差中占8%（R(2)=0.08，p < 0.01），在预测患者症状性生活质量的方差中占7%（R(2)=0.07，p < 0.01）。
本研究强调了患者服用阿片类药物的自我效能感信念对其与癌症疼痛相关的生活质量的潜在重要性。
