简明疼痛清单(BPI；Cleeland and Associates)主要用于评估癌症相关疼痛的患者。尽管它已在多种语言中得到验证并被广泛使用，但尚未发表研究证实其在慢性非恶性疼痛患者中的应用作为主要表现问题。这项研究旨在通过检测440名慢性顽固性疼痛患者的BPI心理测量学特性来填补这一空白，这些患者转诊到一家大都市三级保健教学医院的慢性疼痛诊所。结果表明可接受的内部一致性(Cronbachα系数对于强度项为.85，对于干扰项为.88)。因素分析得到2个独立的因素，支持BPI的2因素结构的效度。零级相关分析表明，BPI干扰与残疾程度(罗兰-莫里斯残疾问卷[RMDQ])的相关性(r=0.57)显著高于BPI强度(r=0.40，t=5.71，P<；0.01)，与BPI干扰的相关性不超过0.80，支持这一结论，即这些量表评估的是相关的但也是不同的维度。最后，随着治疗的进行，两种BPI量表都显示出统计上的显著改善，这一发现证实了BPI在检测和反映随着时间的推移疼痛改善方面的响应性。观点：本文验证了最初为评估癌症疼痛而开发的疼痛评估工具(简明疼痛问卷)的心理测量学特性，并将其扩展到慢性非恶性疼痛人群。这为临床医生治疗慢性疼痛提供了一种重要且广泛使用的诊断工具。(C)2004年，由美国疼痛协会提供。
The Brief Pain Inventory (BPI; Cleeland and associates) has been used primarily to assess patients with cancer-related pain. Although it has been validated in many languages and is widely used, there has not yet been research published to validate its use for patients with chronic nonmalignant pain as the primary presenting problem. This study was designed to fill this gap by examining the psychometric properties of the BPI in 440 patients with chronic intractable pain referred to a chronic pain clinic at a metropolitan tertiary-care teaching hospital. Results indicated acceptable internal consistency (Cronbach alpha coefficients were .85 for the intensity items and .88 for the interference items). A factor analysis resulted in 2 distinct and independent factors, supporting the validity of the 2-factor structure of the BPI. Zero-order correlations indicated that the association with a measure of disability (the Roland-Morris Disability Questionnaire [RMDQ]) was significantly higher for BPI interference (r = 0.57) than for BPI intensity (r = 0.40, t = 5.71, P < .01) and that the correlation with BPI interference was not more than 0.80, supporting the conclusion that these scales assess related, but also distinct, dimensions. Finally, the finding that both BPI scales showed statistically significant improvement with treatment confirms the responsivity of BPI in detecting and reflecting improvement in pain over time.Perspective: This paper validated the psychometric properties of a pain Assessment instrument (The Brief Pain inventory) originally developed to assess cancer pain and extended its use for the chronic nonmalignant pain population. This provides an important and widely used diagnostic tool for the clinician treating chronic pain. (C) 2004 by the American Pain Society.
