Abstract

OBJECTIVE

To summarise the estimates of Cronbach's α for the Child Impact Section (CIS), Family Impact Section (FIS), and total Early Childhood Oral Health Impact Scale (ECOHIS) and to identify the significant predictors that may influence the pooled estimates.

MATERIALS AND METHODS

A systematic search was conducted in PubMed, Scopus, EMBASE, Web of Sciences, Dentistry and Oral Science Source, and CINAHL from inception until 21st November 2024. Included were those reported in English with Cronbach's α values for the ECOHIS or its subscales. Abstracts, conference proceedings, letters to editors, pilot studies, brief communications, and commentary were omitted. Two review authors independently reviewed the title and abstracts and full-text. Data extraction included demographic characteristics, language, study design and setting, sampling, Cronbach's α, and questionnaire item count. COSMIN checklist was used for quality assessment and "Reliability Generalization Meta-analysis" (RGMA) was conducted to estimate the internal consistency of ECOHIS questionnaire.

RESULTS

Overall, 1,524 publications were retrieved, of which 454 and 304 were available for screening title and abstracts and full texts respectively. Among the included 66 publications, 74 estimates were obtained. The pooled Cronbach's α for the total scale was 0.86 with high heterogeneity (I = 95.43). No significant impact of moderators was seen on the pooled estimate. Subgroup analysis showed little variation in the pooled estimates for continent, language, study setting, study design, and type of sampling. Only 46 estimates were included for the RGMA of CIS (0.85) and FIS (0.79). No significant effects of moderators were seen on the pooled Cronbach's α for both CIS and FIS. Similarly, subgroup analysis showed little variation in the pooled estimates for the CIS and FIS for various categorical predictors.

CONCLUSION

The pooled Cronbach's α of ECOHIS and its sub-scales were higher than the acceptable benchmark with no effect of moderators.

摘要

目的

总结儿童影响部分（CIS）、家庭影响部分（FIS）以及早期儿童口腔健康影响量表（ECOHIS）总分的克朗巴哈α系数估计值，并确定可能影响合并估计值的显著预测因素。

材料与方法

从数据库建库至2024年11月21日，在PubMed、Scopus、EMBASE、Web of Sciences、牙科学与口腔科学源数据库以及CINAHL中进行系统检索。纳入以英文报道的、具有ECOHIS或其分量表克朗巴哈α值的研究。排除摘要、会议论文集、给编辑的信件、试点研究、简短通讯和评论。两位综述作者独立审查标题、摘要和全文。数据提取包括人口统计学特征、语言、研究设计与设置、抽样方法、克朗巴哈α系数以及问卷项目数量。使用COSMIN清单进行质量评估，并进行“可靠性概括性元分析”（RGMA）以估计ECOHIS问卷的内部一致性。

结果

总体而言，检索到1524篇出版物，其中分别有454篇和304篇可用于标题和摘要筛选以及全文筛选。在纳入的66篇出版物中，获得了74个估计值。总量表的合并克朗巴哈α系数为0.86，异质性较高（I=95.43）。未观察到调节因素对合并估计值有显著影响。亚组分析显示，在大陆、语言、研究设置、研究设计和抽样类型的合并估计值中差异不大。CIS（0.85）和FIS（0.79）的RGMA仅纳入了46个估计值。未观察到调节因素对CIS和FIS的合并克朗巴哈α系数有显著影响。同样，亚组分析显示，对于各种分类预测因素，CIS和FIS的合并估计值差异不大。
