反应性措施（改变所评估现象的措施）在解释观察到的任何变化时会造成问题。本研究探讨了电子日记的疼痛，活动干扰，情绪和疼痛信念的措施是否反应在可观察到的数据和患者报告的影响。患有慢性颞下颌关节紊乱疼痛的患者（N = 71，86%女性）每天完成3次电子日记，持续约2周，随后报告了对颞下颌关节相关变量的感知影响。73%的患者报告说，评估影响了他们的疼痛，而51%，45%和39%的患者认为这分别影响了他们的日常活动，情绪和信念。相反，在电子日记评级中观察到的反应性的客观证据很少; 14天内的变化很小（例如，在0到10个量表上预测的变化：积极情绪，.1;疼痛，-0.3;感知控制，-0.5）并且没有统计学显著性。主观反应性通常与客观反应性无显著相关性。数据表明，患者认为日常评估疼痛相关的变量有积极和消极的影响，但疼痛相关的措施不显示reactive effects.Perspective：电子日记评估方法有可能增加有关患者的疼痛和疼痛相关变量之间的顺序关系的经验知识，但只有当测量过程是非反应性的。这项研究提供的证据表明，电子日记评估疼痛相关的变量是非反应性的。(C)2005年由美国疼痛学会主办。
Reactive measures (measures that change the phenomenon assessed) cause problems in interpreting any changes observed. This study examined whether electronic daily diary measures of pain, activity interference, mood, and pain beliefs were reactive in terms of both observable data and patient-reported effects. Patients with chronic temporomanclibular disorder pain (N = 71, 86% female) completed electronic diaries 3 times daily for approximately 2 weeks and subsequently reported perceived effects on symptom-related variables. Seventy-three percent of patients reported that the assessment affected their pain, whereas 51%, 45%, and 39% thought that it affected their daily activities, mood, and beliefs, respectively. in contrast, there was little objective evidence of reactivity as observed in the electronic diary ratings; changes over 14 days were small (eg, predicted changes on 0 to 10 scales: positive mood,.1; pain, -.3; perceived control, -.5) and not statistically significant. Subjective reactivity was generally not significantly related to objective reactivity. The data suggest that patients view daily assessment as having positive and negative effects on pain-related variables, but pain-related measures do not show reactive effects.Perspective: Electronic daily diary assessment methods hold the potential to increase knowledge concerning patients' experiences with pain and sequential relations between pain-related variables, but only if the measurement process is nonreactive. This study provides evidence that electronic diary assessment of pain-related variables is nonreactive. (C) 2005 by the American Pain Society.
