TABLE 39.11. FUNCTIONS OF RECORDKEEPING

1. A major problem for pain treatment is the lack of an objective test of improvement. Patients learn a scaling system that has intra-rater reliability. 

2. Patients deliver an accurate record of the pain, which is notoriously poorly remembered (57). Thus they can establish a baseline for daily pain levels that will enable monitoring of treatment effects. 

3. By recording circumstances of pain, patients may learn about the multiple other biopsychosocial factors that may precipitate and perpetuate their pain. 

4. Recordkeeping is therapeutic. The patient finally can do something that helps their treatment, an activity that improves, often immediately, their sense of control and selfefficacy. 

5. By providing a numerical scale to communicate pain levels, recordkeeping serves to extinguish maladaptive pain behaviors that serve as their only means of communicating pain levels and distress and tend to isolate them socially.

表39.11.记录保存的功能

1. 疼痛治疗的一个主要问题是对改善缺乏客观的测试。患者应学习使用一种具有内部可靠评级的评分系统。

2. 病人准确地记录疼痛，这是出了名的记不住(57)。因此，他们可以建立每日疼痛水平的基线，从而能够监测治疗效果。

3. 通过记录疼痛的情况，患者可以了解可能促发和延续其疼痛的多种其他生物心理社会因素。

4. 记录有治疗作用，患者最终通过记录发现可以做一些通常会立即提高他们的控制感和自我效能感的活动以有助于其治疗。

5. 通过提供一个数字量表来传达疼痛水平，记录保存有助于消除不适应的疼痛行为，这些行为作为他们传达疼痛水平和痛苦的唯一手段，并可能因为这些行为而受到社会的孤立。

Patients deliver an accurate record of the pain, which is notoriously poorly remembered (57).病人准确地记录疼痛，这是出了名的记不住(57)？出了名的记不住——出了名的难以记忆？
