Oral Health Assessment: Cross-Cultural Adaptation and Psychometric Properties of the Persian Version of the Oral Assessment Sheet (P-OAS) among Older Adults.

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
backgroundOral health plays a crucial role in personal, social, and psychological well-being, especially in older adults. Currently, no specific assessment tool is available in Iran that provides a multi-dimensional clinical assessment of oral health status. Therefore, this study aimed to examine the psychometric properties and cross-cultural adaptation of the Persian version of the Oral Assessment Questionnaire (P-OAS) for older adults.
methodsThis methodological study employed convenience sampling for participant selection, with data collected via face-to-face interviews at Tooba Clinic in Sari, Iran (April-June 2024). Data were collected using the P-OAS, DMFT index, Gingival Index (GI), and a demographic questionnaire. The P-OAS was translated, culturally adapted, and its psychometric properties were analyzed using SPSS v.22, with statistical significance set at p < 0.05.
resultsA total of 200 participants (mean age: 68.87 years) were included in the study. The mean (SD) scores for P-OAS, DMFT, and GI were 8.37 ± 5.94, 21.55 ± 7.49, and 1.72 ± 0.65, respectively. Experts confirmed face, content (SCVI/average = 0.89), and cross-cultural validity. Confirmatory factor analysis showed a good model fit (GFI = 0.90, CFI = 0.92). P-OAS correlated significantly with the DMFT (p < 0.05, r = 0.45) and GI (p < 0.05, r = 0.56) indices, indicating satisfactory convergent validity. Internal consistency (Cronbach's α = 0.93) and test-retest reliability (ICC = 0.92) were high. No significant floor or ceiling effects were observed. Oral health scores varied significantly by demographic factors, except for marital status and chronic diseases (p > 0.05).
conclusionThe P-OAS demonstrated high validity and reliability, making it a valuable tool for assessing oral health status among older adults.
