There is considerable interest in the role that disturbance of body-perception may play in long standing pain problems such as chronic low back pain (CLBP), both as a contributor to the clinical condition and as a potential target for treatment. In some chronic pain conditions body-perception has been investigated using self-report questionnaires. There is currently no questionnaire for assessing body-perception in people with CLBP.
To describe the development of a back-specific body-perception questionnaire and examine the psychometrics of this new scale.
Based on available evidence a back-specific body-perception questionnaire was developed. Fifty-one people with CLBP and an equal number of healthy controls completed the questionnaire; a subset of the patient population completed the questionnaire again one-week later. Scale-consistency and test-retest reliability were investigated on the patient sample. Validity was investigated by comparing responses between patients and controls as well as exploring the relationship between the questionnaire and important clinical characteristics.
All but one of the patients endorsed items on the questionnaire, which suggests that distorted body-perception may exist in this population. The internal-consistency and test-retest reliability of the scale appear acceptable. The discriminative validity of the questionnaire is supported by the marked differences in the questionnaire responses between patients and healthy controls and the construct validity by the significant association between the questionnaire score and important clinical variables.
Symptoms of body-perception distortion were endorsed by most CLBP patients, while these symptoms are very infrequent amongst healthy controls. Our results suggest the questionnaire has reasonable psychometric properties.
身体感知障碍在诸如慢性下腰痛（CLBP）等长期疼痛问题中可能发挥的作用引起了广泛关注，它既是临床病症的一个促成因素，也是一个潜在的治疗靶点。在一些慢性疼痛病症中，已通过自我报告问卷对身体感知进行了研究。目前尚无用于评估CLBP患者身体感知的问卷。
描述一种针对背部的身体感知问卷的编制过程，并检验这一新量表的心理测量学特性。
基于现有证据编制了一份针对背部的身体感知问卷。51名CLBP患者和数量相等的健康对照者完成了该问卷；部分患者在一周后再次填写了问卷。对患者样本进行了量表一致性和重测信度的调查。通过比较患者和对照者的回答以及探究问卷与重要临床特征之间的关系来调查效度。
除一名患者外，所有患者均认可问卷中的项目，这表明该人群可能存在身体感知扭曲。量表的内部一致性和重测信度似乎可以接受。患者与健康对照者在问卷回答上的显著差异支持了问卷的区分效度，问卷得分与重要临床变量之间的显著关联支持了结构效度。
大多数CLBP患者认可身体感知扭曲的症状，而这些症状在健康对照者中很少见。我们的结果表明该问卷具有合理的心理测量学特性。
