The Control of Allergic Rhinitis and Asthma Test (CARAT10), developed by Portuguese experts, is the only questionnaire assessing asthma control under additional consideration of a frequently concurrent allergic rhinitis (AR), providing sub-scores for both diseases. Aims of this study were the translation and validation of its German version. Asthma patients both with and without AR were included at three primary care pulmologists´ practices in Southern Germany. After translation process, patients completed the CARAT10, the Asthma Control Questionnaire (ACQ), the Asthma Control Test (ACT), and the Standardised Asthma Quality of Life Questionnaire (AQLQ(S)). Item and scale characteristics as well as measures of reliability and validity of the CARAT10 were determined. A confirmatory factor analysis was conducted to test factorial validity. Data of 213 patients were analysed, 101 (47%) of them with concurrent AR. Missing responses were minimal and unsystematic. Cronbach´s α was 0.87 for the CARAT10 total score (TS) and 0.84 for each sub-score. Spearman´s correlation coefficients for the association of the CARAT10 TS with ACQ, ACT and AQLQ(S) were moderate to high and slightly higher in patients with AR. Higher correlations were found for its lower airway sub-score than the upper airway sub-score (all around 0.8 to all around 0.3). Confirmatory factor analysis confirmed the two-factorial scale structure of the CARAT10, with a two-factor model showing a better fit to the data than a one-factor model. The German version of the CARAT10 is an acceptable, reliable and valid tool. Our results suggest a recommended use in asthma patients with AR.

前瞻性观察性研究证实了德语版本的过敏性鼻炎和哮喘控制试验(CARAT10)

葡萄牙专家开发的“控制过敏性鼻炎和哮喘的控制方法”(CARAT10)是唯一在评估哮喘控制情况的调查表中,同时考虑了经常同时发生的过敏性鼻炎(AR),为这两种疾病提供了评分。这项研究的目的是翻译和验证其德语版本。在德国南部,三位初级保健医师都将有或没有AR的哮喘患者纳入研究。经过翻译过程后,患者完成了CARAT10,哮喘控制调查表(ACQ),哮喘控制测试(ACT)和标准化哮喘生活质量调查表(AQLQ(S))。确定了CARAT10的项目和规模特征,以及信度和效度的度量。进行了验证性因子分析以测试因子有效性。分析了213例患者的数据,其中101例(47%)并发AR。缺少的答复很少而且没有系统性。Cronbach的CARAT10总分(TS)的α为0.87,每个子项得分为0.84。在AR患者中,CARAT10 TS与ACQ,ACT和AQLQ(S)的关联的Spearman相关系数为中度到高度,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。101例(47%)并发AR。缺少的答复很少而且没有系统性。Cronbach的CARAT10总分(TS)的α为0.87,每个子项得分为0.84。在AR患者中,CARAT10 TS与ACQ,ACT和AQLQ(S)的关联的Spearman相关系数为中度到高度,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。101例(47%)并发AR。缺少的答复很少而且没有系统性。Cronbach的CARAT10总分(TS)的α为0.87,每个子项得分为0.84。在AR患者中,CARAT10 TS与ACQ,ACT和AQLQ(S)的关联的Spearman相关系数为中度到高度,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。Cronbach的CARAT10总分(TS)的α为0.87,每个子项得分为0.84。在AR患者中,CARAT10 TS与ACQ,ACT和AQLQ(S)的关联的Spearman相关系数为中度到高度,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。Cronbach的CARAT10总分(TS)的α为0.87,每个子项得分为0.84。在AR患者中,CARAT10 TS与ACQ,ACT和AQLQ(S)的关联的Spearman相关系数为中度到高度,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。AR患者的ACT和AQLQ(S)为中度至较高,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。AR患者的ACT和AQLQ(S)为中度至较高,略高。发现其较低的气道子分数比较高的气道子分数具有更高的相关性(均在0.8到0.3附近)。验证性因素分析证实了CARAT10的两因素规模结构,两因素模型显示的数据比单因素模型更好。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。两因素模型显示的数据比一因素模型更适合数据。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明推荐用于AR哮喘患者。两因素模型显示的数据比一因素模型更适合数据。德语版的CARAT10是可以接受,可靠和有效的工具。我们的结果表明,推荐用于AR哮喘患者。
