Introduction

The present study analyzed evidence of validity and internal consistency of the Brazilian version of the COVID-19 Household Environment Scale (CHES). More specifically, we tested validity evidence for: (1) the content of the Brazilian version, which involved two experts experienced in research with LGB couples; (2) exploratory factor analysis and internal consistency through the composite reliability calculation; and (3) external measures through the correlation between the CHES factors (cohesion and conflict) and marital satisfaction.

Method

For the analysis of internal structure, internal consistency and external validity, a sample of 268 childless lesbian, gay and bisexual (LGB) spouses, who lived with their partners during the Covid-19 pandemic from all around Brazil, were used. Participants answered an online questionnaire posted on social media.

Results

In the content stage, i-CVI = 1.00 was found for only 27 items, with 3 items excluded for not being suitable for couples without children (i-CVI = 0.0). Exploratory factor analysis pointed to a two-factor solution for CHES (Conflict and Cohesion). Composite reliability was adequate for both factors, so the instrument’s correlations with marital satisfaction provided initial evidence of validity and suggested an association between the variables.

Conclusion

The findings support the psychometric adequacy of the CHES in line with the original version of the instrument, moreover, evidence is expanded of its validity with LGB spouses without children in the Brazilian context (using 27 items).

Policy Implications

The CHES instrument is a useful tool both for marital and family studies with data collected during and after the COVID-19 pandemic, and for research and clinical initiatives aimed at evaluating post-pandemic family interventions.

巴西版 Covid-19 家庭环境量表：无子女女同性恋、男同性恋和双性恋夫妇的有效性证据

介绍

本研究分析了巴西版本的 COVID-19 家庭环境量表 (CHES) 的有效性和内部一致性证据。更具体地说，我们测试了以下方面的有效性证据：（1）巴西版本的内容，其中涉及两位具有 LGB 夫妇研究经验的专家；(2)通过综合可靠性计算进行探索性因素分析和内部一致性；（3）通过CHES因素（凝聚力和冲突）与婚姻满意度之间的相关性进行外部衡量。

方法

为了分析内部结构、内部一致性和外部有效性，使用了来自巴西各地的 268 名无子女男女同性恋和双性恋 (LGB) 配偶样本，他们在 Covid-19 大流行期间与伴侣住在一起。参与者回答了社交媒体上发布的在线调查问卷。

结果

在内容阶段，仅发现 27 个项目 i-CVI = 1.00，排除了 3 个不适合无孩子夫妇的项目（i-CVI = 0.0）。探索性因素分析指出了 CHES（冲突和凝聚力）的双因素解决方案。这两个因素的综合信度都足够，因此该工具与婚姻满意度的相关性提供了有效性的初步证据，并表明变量之间存在关联。

结论

研究结果支持 CHES 的心理测量充分性与该工具的原始版本一致，此外，证据扩大了其在巴西背景下无子女的 LGB 配偶的有效性（使用 27 项）。

政策影响

CHES 工具是一个有用的工具，既可用于婚姻和家庭研究，可在 COVID-19 大流行期间和之后收集数据，也可用于旨在评估大流行后家庭干预措施的研究和临床举措。
