Disease-related worries constitute an important dimension of patient-reported perception of health status in inflammatory bowel disease (IBD). The Rating Form of IBD Patient Concerns (RFIPC) questionnaire is purported to measure IBD-related worries. This study evaluated the psychometric properties of a Swedish translation of RFIPC in an unselected population of Crohn's disease (CD) patients. The degree and nature of the worries were characterized and predictive factors for outcome of RFIPC and underlying dimensions were identified.
The RFIPC was completed by 447 CD patients in conjunction with regular visits. A physician global assessment of disease activity and four other health-related quality of life (HRQL) questionnaires were used for construct validity. Reliability and responsiveness were evaluated with follow-up visits. Underlying dimension and predictive factors were identified with factor analysis and multiple linear regression analysis.
Test-retest reliability was 0.90, correlation with corresponding HRQL measures 0.60-0.80 and responsiveness ratio 0.84. Median RFIPC sum score was lower than in previous studies. Top three concerns were ostomy, energy level and bowel control. Four dimensions were identified in descending order of concern: disease-related complications, daily-life achievements, intimacy, and stigmatization. Predictors of RFIPC score were disease activity, gender, and BMI (p < 0.001-0.008).
The Swedish version of RFIPC exhibited an adequate psychometric performance in CD patients, but was less sensitive to change in disease activity. The patients were more concerned about complications and achievement than intimacy and stigmatization. The strongest predictors of more worry were active disease, female gender and higher BMI.
疾病相关担忧是炎症性肠病（IBD）患者报告的健康状况感知的一个重要维度。炎症性肠病患者担忧评定量表（RFIPC）问卷旨在测量与IBD相关的担忧。本研究评估了RFIPC瑞典语翻译版在未经选择的克罗恩病（CD）患者群体中的心理测量特性。对担忧的程度和性质进行了描述，并确定了RFIPC结果及潜在维度的预测因素。
447名CD患者在定期就诊时完成了RFIPC问卷。使用医生对疾病活动的整体评估以及其他四份与健康相关的生活质量（HRQL）问卷来评估结构效度。通过随访评估信度和反应度。使用因子分析和多元线性回归分析确定潜在维度和预测因素。
重测信度为0.90，与相应HRQL测量的相关性为0.60 - 0.80，反应度比率为0.84。RFIPC总分中位数低于先前研究。最主要的三个担忧是造口术、能量水平和肠道控制。确定了四个按担忧程度降序排列的维度：疾病相关并发症、日常生活成就、亲密关系和污名化。RFIPC评分的预测因素是疾病活动、性别和体重指数（p < 0.001 - 0.008）。
RFIPC瑞典语版在CD患者中表现出足够的心理测量性能，但对疾病活动变化的敏感性较低。患者更关注并发症和成就，而非亲密关系和污名化。更多担忧的最强预测因素是疾病活动、女性性别和较高的体重指数。
