Validation of the Arab Mental Health Continuum Short Form (AMHC-SF) in Oman: Psychometric properties and factorial structure.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundThe Mental Health Continuum-Short Form (MHC-SF) is a widely used instrument designed to assess three dimensions of positive mental health: emotional, social, and psychological well-being. However, there is limited evidence regarding its validity within Arab populations.
methodThis study aimed to validate the Arabic version of the MHC-SF (AMHC-SF) among a community-based sample in Oman. A total of 1,101 participants aged 18-65 years (M = 31.49, SD = 9.69) completed the questionnaire through an online survey. Confirmatory factor analyses (CFA) were performed to examine factorial validity, while internal consistency reliability was assessed using Cronbach's alpha and McDonald's omega coefficients. Discriminant validity was examined through correlations with anxiety scales.
resultsConfirmatory factor analysis supported the superiority of the bifactor model over the original three-factor structure, demonstrating excellent model fit (CFI = 0.99, TLI = 0.98, RMSEA = 0.032) and substantial general factor loadings (0.64-0.76). Reliability estimates for the total scale and subscales were excellent, with Cronbach's alpha and McDonald's omega coefficients ranging from 0.86 to 0.95. The AMHC-SF also showed apparent discriminant validity, as higher well-being scores were associated with lower anxiety levels.
conclusionThe findings support the factorial validity, reliability, and discriminant validity of the AMHC-SF, confirming its cross-cultural applicability within the Arab context. The scale represents a brief, psychometrically sound instrument for assessing positive mental health among adults in Oman and other Arabic-speaking populations.
