Abstract:
Medical mistrust is an important barrier to accessing health care among Latinx populations in the United States (US). However, research on the validity and reliability of medical mistrust scales is limited. We examined the validity and reliability of a modified bilingual version of the Group-Based Medical Mistrust scale (mGBMMS) among a sample of Latinx adults. Participants included 308 Latinx adults (ages 18-25), who responded in Spanish (n = 134) or English (n = 174). Following feedback from bilingual/bicultural staff during the English-Spanish translation process, we made three changes to the original GBMMS. Validation testing of our 12-item mGBMMS scale included: split-half and internal consistency reliability; discriminant, convergent, and predictive validity; and both exploratory and confirmatory factor analyses. The mGBMMS had good internal consistency (overall sample: Cronbach\'s α = 0.79; Spanish: Cronbach\'s α = 0.73; English: Cronbach\'s α = 0.83). The mGBMMS showed good convergent (moderately correlated with the experiences of discrimination scale, r = 0.46, p < 0.001) and discriminant (weakly correlated with the acculturation scale, r = 0.11, p = 0.06) validity. Split-half reliability was 0.71 (p < 0.001). Exploratory and confirmatory factor analyses found a two-factor solution. The mGBMMS was associated with satisfaction with care (OR = 0.60, 95%CI: 0.42-0.87), a sign of good predictive validity. Findings suggest that the mGBMMS is a valid and reliable scale to utilize among bilingual (Spanish/English) populations in the US. Further validation studies should be considered among Latinx respondents of different ages, backgrounds, languages, and US regions.
摘要:
医疗不信任是美国(US)拉丁裔人群获得医疗保健的重要障碍。然而,医学不信任量表的效度和信度研究有限。我们在拉丁裔成年人样本中检查了基于群体的医学不信任量表(mGBMMS)的改良双语版的有效性和可靠性。参与者包括308名拉丁裔成年人(18-25岁),他们用西班牙语(n=134)或英语(n=174)回答。在英语-西班牙语翻译过程中,根据双语/双文化工作人员的反馈,我们对原来的GBMMS做了三个改动.我们的12项mGBMMS量表的验证测试包括:半分割和内部一致性可靠性;判别式,convergent,和预测效度;以及探索性和验证性因素分析。mGBMMS具有良好的内部一致性(总体样本:Cronbach'sα=0.79;西班牙语:Cronbach'sα=0.73;英语:Cronbach'sα=0.83)。mGBMMS表现出良好的收敛性(与歧视量表的经验中度相关,r=0.46,p<0.001)和判别(与文化适应量表弱相关,r=0.11,p=0.06)有效性。分裂半信度为0.71(p<0.001)。探索性和验证性因素分析发现了双因素解决方案。mGBMMS与护理满意度相关(OR=0.60,95CI:0.42-0.87),良好的预测有效性的标志。研究结果表明,mGBMMS是在美国双语(西班牙语/英语)人群中使用的有效且可靠的量表。应在不同年龄的拉丁裔受访者中考虑进一步的验证研究,背景,语言,和美国地区。
