Valid and reliable measures of patients' pain beliefs are needed by clinicians and researchers to better understand the efficacy and mechanisms of pain treatments. The objective of this work was to address this need by further developing the pediatric version of the Survey of Pain Attitudes (Peds-SOPA), one of the most commonly used measures of pain beliefs.
A convenience sample of three hundred and seven adolescents (mean age= 14.35; SD=1.62; 59% girls) participated in the study. They rated the intensity of their worst pain experienced in the 3 months prior to the assessment and completed both the Functional Disability Inventory and a revised version of a pediatric version of the Survey of Pain Attitudes (Peds-SOPA-R).
Factor analyses confirmed a seven-factor solution of the questionnaire, and the revised version demonstrated improvements in the internal consistency of several of the scales (values ranged between adequate and good: 0.71-0.87), except for the Medical Cure scale which showed an internal consistency value of 0.65. The results support the validity of the Peds-SOPA-R scale scores by showing, as predicted, positive relationships between beliefs thought to be maladaptive (e.g., the belief that one is unable to function because of pain) and pain intensity and disability, and negative relationships with beliefs thought to be adaptive (e.g., the belief that exercise is beneficial for pain management) and these criterion variables.
These findings will be helpful to researchers who wish to study the role that pain beliefs play in adjustment to pain in youth.
The results provide critical psychometric information about a revised version of one of the most used questionnaires to assess pain beliefs. The evidence presented will be helpful to researchers who want to study the role that pain beliefs play in adjustment to chronic pain in young people.
临床医生和研究人员需要有效且可靠的患者疼痛信念测量方法，以便更好地理解疼痛治疗的疗效和机制。本研究的目的是通过进一步开发疼痛态度调查儿科版（Peds - SOPA）来满足这一需求，该量表是最常用的疼痛信念测量工具之一。
共有307名青少年（平均年龄 = 14.35；标准差 = 1.62；59%为女孩）参与了这项便利样本研究。他们对评估前3个月内经历的最严重疼痛强度进行评分，并完成了功能残疾量表和疼痛态度调查儿科版修订版（Peds - SOPA - R）。
因子分析确定了问卷的七因子结构，修订版在几个量表的内部一致性方面有所改善（值在适当到良好之间：0.71 - 0.87），除了医疗治愈量表，其内部一致性值为0.65。结果支持了Peds - SOPA - R量表分数的有效性，正如预期所示，被认为是适应不良的信念（例如，认为因疼痛而无法正常生活的信念）与疼痛强度和残疾之间呈正相关，而与被认为是适应性的信念（例如，认为运动对疼痛管理有益的信念）与这些标准变量之间呈负相关。
这些发现将有助于希望研究疼痛信念在青少年疼痛适应中所起作用的研究人员。
研究结果提供了关于评估疼痛信念最常用问卷之一的修订版的关键心理测量信息。所呈现的证据将有助于想要研究疼痛信念在年轻人慢性疼痛适应中所起作用的研究人员。
