In our study, we investigated the predictive value of illness beliefs as measured by the revised illness perception questionnaire (IPQ-R) in the context of other clinical predictors in patients with chronic orofacial pain over a 6-month follow-up period. Consecutive patients (152) referred to the interdisciplinary orofacial pain service at the Centre for Dental and Oral Medicine and Cranio-Maxillofacial Surgery, University of Zurich received questionnaires to assess pain and pain-related disability, anxiety, depression as well as physical and mental quality of life at three time points: prior to treatment, 3 and 6 months after beginning of treatment.
significant improvement was found over time for all outcome measures except mental quality of life. RESULTS of the regression analysis indicated that believing pain could have serious consequences on one's life (IPQ subscale consequences) is one of the most important predictors for treatment outcome. The belief in low personal control and in a chronic timeline is also shown to be predictive for outcome, though explaining a smaller proportion of variance. These results provided evidence that beliefs about pain are important predictors for treatment outcome even when controlled for pain and mood. They therefore need to be considered in the management of patients with chronic orofacial pain. Assessing patients' illness beliefs can provide essential information on these important psychological determinants of adjustment to chronic pain and may be specific targets for individualised treatment approaches.
在我们的研究中，我们调查了在慢性颌面疼痛患者中，经过 6 个月的随访，修订后的疾病感知问卷（IPQ-R）测量的疾病信念在其他临床预测因素背景下的预测价值。连续患者（152 名）被转介到苏黎世大学牙和口腔医学中心和颅面外科的跨学科颌面疼痛服务处，在三个时间点接受问卷评估疼痛和疼痛相关残疾、焦虑、抑郁以及身体和精神生活质量：治疗前、治疗开始后 3 个月和 6 个月。
除精神生活质量外，所有结果测量均随时间显著改善。回归分析结果表明，相信疼痛会对一个人的生活产生严重后果（IPQ 子量表后果）是治疗结果最重要的预测因素之一。对个人控制和慢性时间线的低信念也被证明是具有预测性的，尽管解释的方差较小。这些结果表明，即使在控制疼痛和情绪的情况下，对疼痛的信念也是治疗结果的重要预测因素。因此，它们需要在慢性颌面疼痛患者的管理中加以考虑。评估患者的疾病信念可以提供有关慢性疼痛适应的这些重要心理决定因素的重要信息，并且可能是个体化治疗方法的特定目标。
