在美国，大约70%的5岁或5岁以上的拉丁美洲人在家里说西班牙语。PROMISA（R）疼痛干扰（PI）项目库按管理语言（英语与西班牙语）的测量等效性尚未评估。527名讲西班牙语的成年拉丁美洲人完成了西班牙语版本的41项PROMISA（R）疼痛干扰项目库。我们评估西班牙语项目的维数，单调性和局部独立性。然后，我们使用有序逻辑回归法评估差异项目功能（DIF），其中项目反应理论得分是从无DIF的“锚”项目中估计的。PROMISA（R）PI项目库的西班牙语版本中的41个项目中的一个被确定为具有显著一致的DIF。PI题库。由于专利问题，未保留此项目。在估计PROMISA（R）PI评分时，可使用原始英语项目参数。
About 70% of Latinos, 5 years old or older, in the United States speak Spanish at home. Measurement equivalence of the PROMISA (R) pain interference (PI) item bank by language of administration (English versus Spanish) has not been evaluated.A sample of 527 adult Spanish-speaking Latinos completed the Spanish version of the 41-item PROMISA (R) pain interference item bank. We evaluate dimensionality, monotonicity and local independence of the Spanish-language items. Then we evaluate differential item functioning (DIF) using ordinal logistic regression with item response theory scores estimated from DIF-free "anchor" items.One of the 41 items in the Spanish version of the PROMISA (R) PI item bank was identified as having significant uniform DIF.English- and Spanish-speaking subjects with the same level of pain interference responded differently to 1 of the 41 items in the PROMISA (R) PI item bank. This item was not retained due to proprietary issues. The original English language item parameters can be used when estimating PROMISA (R) PI scores.
