Although household disinfectant cleaners are used at home frequently, less research has focused on standardized assessment tools to measure public awareness and precautions in practice, especially during health crises. The COVID-19 pandemic highlighted the important role of household disinfectants-cleaners in preventing infections. However, poor public awareness and unsafe practices can undermine their effectiveness. This study indirectly addresses this lack by developing and validating the Household Disinfectants-Cleaners Questionnaire (HDCQ), to make available an evidence-based comprehensive tool to support future assessments, public health research, and policy development.
To assess the validity and reliability of a questionnaire designed to measure public awareness and performance regarding the safe use of household disinfectants-cleaners in Abu Dhabi.
A cross-sectional Google survey, involving a sample of 750 Abu Dhabi residents, was analyzed using IBM-SPSS (Version 27.0) and RStudio (Version 1.1.456, Inc., 2009-2018). Validity tests included face, content, and construct evaluations by nine academic experts based on seven parameters. Reliability was assessed through Cronbach's alpha and inter-item correlation. Principal Factor Analysis (PFA), including the Kaiser-Meyer-Olkin (KMO) measure and Bartlett's test, was conducted for each section in SPSS. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) in RStudio identified the underlying factors explaining item covariation.
Cronbach's alpha values for the awareness and performance domains were 0.854 and 0.883, indicating high internal consistency. Expert ratings indicated high face validity, with importance levels ranging from 0.89 to 1.00. The average Content Validity Ratio (CVR) for the questionnaire was 0.95, indicating strong content relevance. The PFA results demonstrated adequate sampling adequacy, with a KMO measure values of 0.879 and 0.891 and Bartlett's test was statistically significant (χ2 = 2,368, P < 0.001) and (χ2 = 3,274, P < 0.001) for each section respectively, confirming factorability and suitability for factor analysis. Both EFA and CFA indicated a good model fit with RMSEA of 0.077 for Sect. 1 and 0.090 for Sect. 2, CFI of 0.990 for Sect. 1 and 0.975 for Sect. 2, and TLI of 0.986 for Sect. 1 and 0.967 for Sect. 2, confirming the robustness of the factor structure and the questionnaire's validity.
The findings demonstrate that this questionnaire is a valid and reliable tool for assessing public awareness and performance regarding the safe use of household disinfectants-cleaners for future pandemics. Recognizing inherent limitations, detailed in the conclusion section, is essential for effective application in public health contexts.
尽管家用消毒清洁剂在家中经常使用，但较少有研究关注用于衡量公众在实际操作中的意识和预防措施的标准化评估工具，尤其是在健康危机期间。新冠疫情凸显了家用消毒清洁剂在预防感染方面的重要作用。然而，公众意识淡薄和不安全的做法可能会削弱其有效性。本研究通过开发和验证家用消毒清洁剂问卷（HDCQ）间接解决了这一不足，以便提供一个基于证据的综合工具，以支持未来的评估、公共卫生研究和政策制定。
评估一份旨在衡量阿布扎比公众对安全使用家用消毒清洁剂的意识和行为表现的问卷的有效性和可靠性。
通过谷歌进行了一项横断面调查，涉及750名阿布扎比居民的样本，使用IBM-SPSS（版本27.0）和RStudio（版本1.1.456，公司，2009 - 2018）进行分析。效度测试包括由九位学术专家基于七个参数进行的表面效度、内容效度和结构效度评估。通过克朗巴哈系数和项目间相关性评估信度。在SPSS中对每个部分进行主成分分析（PFA），包括凯泽-迈耶-奥尔金（KMO）度量和巴特利特检验。在RStudio中进行探索性因子分析（EFA）和验证性因子分析（CFA），以确定解释项目协变的潜在因子。
意识和行为表现领域的克朗巴哈系数值分别为0.854和0.883，表明内部一致性较高。专家评分表明表面效度较高，重要性水平在0.89至1.00之间。问卷的平均内容效度比率（CVR）为0.95，表明内容相关性较强。PFA结果显示抽样充分性良好，每个部分的KMO度量值分别为0.879和0.891，巴特利特检验具有统计学意义（χ2 = 2368，P < 0.001）和（χ2 = 3274，P < 0.001），证实了因子可分解性和适合进行因子分析。EFA和CFA均表明模型拟合良好，第1部分的RMSEA为0.077，第2部分为0.090；第1部分的CFI为0.990，第2部分为0.975；第1部分的TLI为0.986，第2部分为0.967，证实了因子结构的稳健性和问卷的效度。
研究结果表明，该问卷是评估公众对未来大流行期间安全使用家用消毒清洁剂的意识和行为表现的有效且可靠的工具。认识到结论部分详细阐述的固有局限性对于在公共卫生背景下的有效应用至关重要。
