This study aimed to develop and validate a scale with appropriate psychometric properties to measure satisfaction with cleanliness in adults from San Román, Peru. Using a quantitative, non-experimental, cross-sectional design, data were collected from 400 participants for exploratory factor analysis (EFA) and 466 for confirmatory factor analysis (CFA). The resulting 19-item Cleanliness Satisfaction Scale (ESL-AK) comprises four dimensions: Fresh Waste, Dust Residues, Cleaning Quality, and Visual Impact. The scale demonstrated strong content validity (Aiken’s V = 0.95) and an adequate factorial structure (KMO = 0.931; Bartlett’s test <.001; total variance explained = 58.3%). CFA confirmed the model’s good fit (CFI = 0.960, TLI = 0.953, RMSEA = 0.075, SRMR = 0.038), with factor loadings ranging from λ = 0.63 to λ = 0.91. Reliability analyses indicated high internal consistency (α = 0.862 to 0.902; ω = 0.864 to 0.903). Invariance testing across sex-supported configural, metric, and partial scalar invariance (ΔCFI ≤ 0.002) confirms that the scale operates similarly for males and females and enables valid latent mean comparisons. These results support the ESL-AK as a valid and reliable instrument for assessing cleanliness satisfaction.

本研究旨在开发并验证一个具有适当心理测量特性的量表，以测量秘鲁圣罗曼成年人对清洁度的满意度。采用定量、非实验性横断面设计，收集了400名参与者的数据用于探索性因子分析（EFA），466名参与者的数据用于验证性因子分析（CFA）。最终得到的包含19个条目的清洁满意度量表（ESL-AK）包括四个维度：新鲜垃圾、灰尘残留、清洁质量和视觉影响。该量表显示出很强的内容效度（艾肯指数V = 0.95）和适当的因子结构（KMO = 0.931；巴特利特检验＜.001；总方差解释率 = 58.3%）。验证性因子分析证实模型拟合良好（CFI = 0.960，TLI = 0.953，RMSEA = 0.075，SRMR = 0.038），因子载荷范围为λ = 0.63至λ = 0.91。信度分析表明内部一致性较高（α = 0.862至0.902；ω = 0.864至0.903）。跨性别不变性检验支持构型不变性、度量不变性和部分标量不变性（ΔCFI≤0.002），证实该量表在男性和女性中运行方式相似，能够进行有效的潜在均值比较。这些结果支持ESL-AK作为评估清洁满意度的有效且可靠的工具。
