The effect yielded by the degree of differentiation of two methods for measuring pain on patient statements regarding the extent of clinical pain was analyzed. At the same time, the reference time frame for the patient reports was varied.
The influence exerted by differentiated questioning was determined by comparing two pictorial body diagrams. Three reference time frames were specified (current pain, last week, last half year).
Patients with wide-spread pain reacted stronger to variations in differentiated questioning the older the pain experienced was and the longer the time frame reported on. Upon differentiated questioning, patients with juxta-articular pain however remembered a lower number of pain sites in the past than on global assessment. Patients with backache reported their current pain to be less widely spread when assessed differentially than on global assessment.
Patient reports on the extent of pain mainly differ in those patients with extensive pain depending on the degree of differentiation during questioning. In these cases, the probability is high that the symptomatic complaints first became established, at least in part, as a reaction to the situational questioning conditions and therefore cannot be generalized to other questioning conditions.
分析两种疼痛测量方法的分化程度对患者关于临床疼痛程度陈述的影响。同时，改变患者报告的参考时间范围。
通过比较两幅人体示意图确定分化提问所产生的影响。指定了三个参考时间范围（当前疼痛、上周、过去半年）。
疼痛范围广泛的患者，经历疼痛的时间越久且报告的时间范围越长，对分化提问的变化反应越强。然而，对于关节周围疼痛的患者，在分化提问时，他们回忆起过去疼痛部位的数量比整体评估时要少。背痛患者在进行分化评估时报告其当前疼痛的范围比整体评估时要小。
患者关于疼痛程度的报告在很大程度上因疼痛范围广泛的患者在提问时的分化程度而异。在这些情况下，很有可能症状性主诉至少部分是对情境性提问条件的反应而首次形成，因此不能推广到其他提问条件。
