Abstract

Background

An observer-rated screening questionnaire for dementia for people with intellectual disabilities (ID), DSQIID, was developed in the UK. So far, the German version has not yet been validated in adults with ID.

Aims/Methods

We validated a German version of DSQIID (DSQIID-G) among adults with ID attending a German clinic.

Procedures/Outcomes

DSQIID-G was completed by the caregivers of 104 adults with ID at baseline (T1), 94 at six months (T2) and 83 at 12 months (T3). A Receiver Operating Curve (ROC) was used to determine the total DSQIID-G cutoff score for the best fit between sensitivity and specificity.

Results

Sixteen of the 104 participants at T1 (15%) received a diagnosis of dementia. At T1, the scores among the non-dementia group ranged from 0 to 33 (mean: 6.7; SD: 7.65), and the dementia group ranged from 3 to 43 (mean: 22.12; SD: 11.6). The intergroup difference was statistically significant (W: 158; p < .001) (AUC:.89). A total score of 9 provided the best fit between sensitivity (.94) and specificity (.72).

Conclusions and Implications

DSQIID-G total score can discriminate between dementia and non-dementia cases in adults with ID. A lower cutoff score with a higher sensitivity is desirable for a screening instrument.

在成年智障人士中验证德文版 DSQIID

背景由观察者评分的智障人士痴呆症筛查问卷 DSQIID 由英国开发。程序/结果104 名成年智障人士的照顾者分别在基线（T1）、6 个月（T2）和 12 个月（T3）时填写了 DSQIID-G 的问卷，其中 94 人填写了问卷，83 人填写了问卷。采用接收者工作曲线（ROC）来确定灵敏度和特异性之间最匹配的 DSQIID-G 临界总分。结果104 名参与者中有 16 人（15%）在 T1 时被诊断为痴呆。在 T1 阶段，非痴呆组的得分范围为 0 到 33（平均值：6.7；标清值：7.65），痴呆组的得分范围为 3 到 43（平均值：22.12；标清值：11.6）。组间差异具有统计学意义（W：158；p <；.001）（AUC：.89）。总分 9 分是灵敏度（.94）和特异度（.72）之间的最佳匹配值。结论和启示DSQIID-G 总分可以区分智障成人痴呆和非痴呆病例。对于筛查工具而言，较低的临界值和较高的灵敏度是可取的。

期刊介绍： Research In Developmental Disabilities is aimed at publishing original research of an interdisciplinary nature that has a direct bearing on the remediation of problems associated with developmental disabilities. Manuscripts will be solicited throughout the world. Articles will be primarily empirical studies, although an occasional position paper or review will be accepted. The aim of the journal will be to publish articles on all aspects of research with the developmentally disabled, with any methodologically sound approach being acceptable.
