OBJECTIVE
Based on theories regarding cognitive representations of illness and processes of conceptual change, a representational intervention to decrease cancer pain (RIDcancerPain) was developed and its efficacy tested.
DESIGN
A two-group RCT (RIDcancerPain versus control) with outcome and mediating variables assessed at baseline (T1) and 1 and 2 months later (T2 and T3). Subjects were 176 adults with pain related to metastatic cancer.
MAIN OUTCOME MEASURES
Outcome variables were two pain severity measures (BPI and TPQM), pain interference with life, and overall quality of life. Mediating variables were attitudinal barriers to pain management and coping (medication use).
RESULTS
One hundred and fifty subjects completed the study. Subjects in RIDcancerPain (T1-T2 and T1-T3) showed greater decreases in Barrier scores than those in control. Subjects in RIDcancerPain (T1-T3) showed greater decreases in pain severity than those in control. Change in Barriers scores mediated the effect of RIDcancerPain on pain severity.
CONCLUSION
RIDcancerPain was efficacious with respect to some outcomes. Further work is needed to strengthen it.
目的
基于疾病认知表征和概念转变过程的理论，开发了一种减轻癌症疼痛的表征干预方法（RIDcancerPain）并测试了其疗效。
设计
一项两组随机对照试验（RIDcancerPain组与对照组），在基线（T1）、1个月后（T2）和2个月后（T3）评估结果变量和中介变量。研究对象为176名患有转移性癌症相关疼痛的成年人。
主要结局指标
结局变量为两种疼痛严重程度指标（简明疼痛量表和总体疼痛质量量表）、疼痛对生活的干扰以及总体生活质量。中介变量为疼痛管理和应对的态度障碍（药物使用情况）。
结果
150名受试者完成了研究。RIDcancerPain组（T1-T2和T1-T3）的障碍得分下降幅度大于对照组。RIDcancerPain组（T1-T3）的疼痛严重程度下降幅度大于对照组。障碍得分的变化介导了RIDcancerPain对疼痛严重程度的影响。
结论
RIDcancerPain在某些结局方面有效。需要进一步开展工作以强化该方法。
