Development and validation of the cleanliness satisfaction scale (ESL-AK) in a sample of adults from the Province of San Román, Perú.
Article in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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 p <.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.
