Abstract Background 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 disinfectants-cleaners preventing infections. However, poor unsafe practices can undermine their effectiveness. This study indirectly addresses this lack by developing validating Household Disinfectants-Cleaners Questionnaire (HDCQ), make available an evidence-based comprehensive tool support future assessments, research, policy development. Objective To assess validity reliability a questionnaire designed performance regarding safe use Abu Dhabi. Methods A cross-sectional Google survey, involving sample 750 Dhabi residents, was analyzed using IBM-SPSS (Version 27.0) RStudio 1.1.456, Inc., 2009–2018). Validity tests included face, content, construct evaluations nine academic experts based seven parameters. Reliability assessed through Cronbach’s alpha inter-item correlation. Principal Factor Analysis (PFA), including Kaiser–Meyer–Olkin (KMO) Bartlett’s test, conducted for each section SPSS. Exploratory (EFA) Confirmatory (CFA) identified underlying factors explaining item covariation. Results values domains were 0.854 0.883, indicating high internal consistency. Expert ratings indicated face validity, with importance levels ranging from 0.89 1.00. average Content Ratio (CVR) 0.95, strong content relevance. PFA results demonstrated adequate sampling adequacy, KMO 0.879 0.891 test statistically significant (χ2 = 2,368, P < 0.001) 3,274, respectively, confirming factorability suitability factor analysis. Both EFA CFA good model fit RMSEA 0.077 Sect. 1 0.090 2, CFI 0.990 0.975 TLI 0.986 0.967 robustness structure questionnaire’s validity. Conclusions findings demonstrate that is valid reliable assessing pandemics. Recognizing inherent limitations, detailed conclusion section, essential effective application contexts.
