The DV-QoL is a 17-item questionnaire measuring health-related quality of life in patients affected by symptomatic diverticular disease, covering four domains: physical symptoms, concerns, feelings, and behavioral changes. Given the lack of a diverticulitis-specific questionnaire to be used for German-speaking patients, we prospectively validated the German version of the DV-QoL.
German-speaking patients with CT-confirmed history of recurrent diverticular disease admitted to a Swiss surgical department completed the German version of the DV-QoL, along with short form-36 (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI). Reliability was examined using exploratory and confirmatory factor analysis, a Martin-Loef test, and Cronbach's alpha. For convergent validity testing, correlations were calculated with the GIQLI and SF-36. Discriminant validity tests included age and gender.
We included 121 patients, of whom 77 were admissions for elective surgery and 44 presented with acute diverticulitis treated conservatively. The DV-QoL's total score showed good correlations with the GIQLI (r = - 0.77) and its subscales (r = - 0.76 to - 0.45), as well as with the SF-36's subscales (r = - 0.30 to - 0.57). No relationships were found with age or gender (p < 0.05). The Cronbach's alpha coefficient was 0.89 over all items and 0.69, 0.90, 0.78, and 0.77 for the four separated domains (physical symptoms, cognitions/concerns, feelings, and behavioral changes, respectively). A nonsignificant Martin-Loef test indicated unidimensionality (p = 1), further supported by the exploratory factor analysis, which showed an item information sharing of 65%.
The German DV-QoL questionnaire can be used as a valid and reliable disease-specific measure for quality of life in patients with recurrent diverticular disease.
DV-QoL 是一个包含 17 个项目的问卷，用于测量患有症状性憩室疾病的患者的健康相关生活质量，涵盖四个领域：身体症状、担忧、感觉和行为变化。鉴于缺乏用于德语患者的憩室炎特异性问卷，我们前瞻性地验证了 DV-QoL 的德语版本。
在瑞士外科部门接受 CT 证实的复发性憩室疾病的德语患者填写了 DV-QoL 德语版，以及简明 36 项健康调查（SF-36）和胃肠道生活质量指数（GIQLI）。使用探索性和验证性因子分析、马丁-洛夫检验和克朗巴赫α检验来检查可靠性。为了进行收敛有效性测试，计算了与 GIQLI 和 SF-36 的相关性。区分有效性测试包括年龄和性别。
我们纳入了 121 名患者，其中 77 名因择期手术入院，44 名因急性憩室炎保守治疗。DV-QoL 的总分与 GIQLI（r=-0.77）及其子量表（r=-0.76 至-0.45）以及 SF-36 的子量表（r=-0.30 至-0.57）具有良好的相关性。与年龄或性别无关（p<0.05）。所有项目的克朗巴赫α系数为 0.89，四个分开的领域（身体症状、认知/担忧、感觉和行为变化）分别为 0.69、0.90、0.78 和 0.77。无显著马丁-洛夫检验表明具有单维性（p=1），进一步得到探索性因子分析的支持，该分析显示项目信息共享率为 65%。
德国 DV-QoL 问卷可作为复发性憩室疾病患者生活质量的有效可靠的疾病特异性测量工具。
