目的：本研究的目的是评估儿童口腔健康影响量表（COHIP）的信度、收敛效度和判别效度。该问卷包括五个领域，评估口腔健康，功能健康，社会情感健康，学校环境和自我形象。COHIP旨在测量8至15岁儿童自我报告的口腔健康相关生活质量（OHRQoL），使用积极和消极措辞的项目。方法：从美国和加拿大的儿科、正畸和颅面临床环境中招募儿童。一个不寻求牙科治疗的儿童对照组是从两所美国小学招募的。参与者包括157名儿童，152名正畸和110名颅面畸形患者，以及104名社区参与者。量表信度采用Cronbach’s α系数进行评定。通过组内相关性和配对t检验对未报告健康变化的一部分参与者进行了重新测试的可靠性检查。判别有效性进行了评估，在两种方式：（i）的COHIP评分的四组儿童（三个临床和一个社区居住）进行了比较，方差分析和（ii）的两个临床组，COHIP评分和临床指标之间的关联进行了计算。使用COHIP评分和控制人口统计学变量的全球健康评级之间的部分斯皮尔曼相关性检查收敛效度。结果如下：儿童（n = 523）平均年龄为11.6岁（SD = 1.60）; 51.6%为女性;代表不同种族（黑人= 22.4%，拉丁裔= 32.1%，白色35.1%，其他10.4%）。儿童的总体COHIP评分范围为28至135（平均SD，99.0 - 19.2）。总体COHIP量表的信度非常好：总体评分的Cronbach α系数= 0.91。总体COHIP的重测信度也非常好（ICC = 0.84），并且随着时间的推移，评分没有统计学显著变化。三个临床组之间的显著差异（P = 0.003总体COHIP）支持判别效度：颅面组报告的总体COHIP生活质量评分最低的临床组。在儿童牙科组中，有较大龋齿的儿童报告的COHIP评分较低，表明OHRQoL较低（r =-0.26，P = 0.02），在正畸组中，有较大覆盖的儿童报告的COHIP评分较低（r =-0.25，P = 0.005）。在控制了参与者年龄、性别和种族的影响后，总体COHIP评分与全球健康评级之间的相关性具有统计学意义（P < 0.05），三个临床组的强度相似（儿童牙科= 0.29，正畸= 0.23，结论COHIP具有良好的信度和重测信度。四组儿童之间和四组儿童内部的比较都支持COHIP的区分效度和收敛效度。进一步的测试将检查该仪器在临床和流行病学样本中的效用。
Objectives: The purpose of the current study was to assess the reliability as well as the convergent and discriminant validity of the Child Oral Health Impact Profile (COHIP). The questionnaire consisted of five domains that assessed oral health, functional well-being, social-emotional well-being, school environment, and self-image. COHIP was designed to measure self-reported oral health-related quality of life (OHRQoL) of children between ages 8 and 15 years old, using both positively and negatively worded items. Methods: Children were recruited from pediatric, orthodontic, and craniofacial clinical settings in the USA and Canada. A comparison group of children not seeking dental treatment was recruited from two US elementary schools. Participants included 157 pediatric, 152 orthodontic and 110 patients with craniofacial anomalies, and 104 community-based participants. Scale reliability was assessed with Cronbach's alpha coefficient. Retest reliability was examined by intraclass correlation and paired t-test for a subset of participants who did not report a health change. Discriminant validity was assessed in two ways: (i) the COHIP scores of the four groups of children (three clinical and one community-dwelling) were compared by ANOVA and (ii) for two of the clinical groups, the association between COHIP scores and clinical indices was calculated. Convergent validity was examined using partial Spearman correlations between COHIP scores and Global Health Ratings controlling for demographic variables. Results: The children (n = 523) averaged 11.6 years (SD = 1.60); 51.6 % were female; and represented diverse ethnicities (black = 22.4%, Latino = 32.1%, white 35.1%, other 10.4%). Overall COHIP scores ranged from 28 to 135 (mean SD, 99.0 19.2) for the children. Scale reliability for the overall COHIP was excellent: Cronbach's alpha coefficient = 0.91 for the overall score. The test-retest reliability of the overall COHIP was also excellent (ICC = 0.84) and there was no statistically significant shift in scores over time. Discriminant validity was supported by significant differences (P = 0.003 overall COHIP) among the three clinical groups: the craniofacial group reported the lowest overall COHIP quality of life scores of the clinical groups. Within the pediatric dental group, children with greater dental decay reported lower COHIP scores suggesting a lower OHRQoL (r = -0.26, P = 0.02) and within the orthodontic group, children with larger overjet reported lower COHIP scores (r = -0.25, P = 0.005). Controlling for the effect of the participants age, gender, and ethnicity, the association between the overall COHIP score and Global Health rating was statistically significant (P < 0.05) and similar in strength for the three clinical groups (pediatric dental = 0.29, orthodontic = 0.23, and craniofacial = 0.24) and highest for the community group (0.36).Conclusiom The overall COHIP showed excellent scale reliability overall and test-retest reliability. Both discriminant and convergent validity of the COHIP were supported by the comparisons among and within the four groups of children. Further testing will examine the utility of the instrument in both clinical and epidemiological samples.
