Psychometric properties of the Persian Brief Suicide Cognitions Scale (B-SCS): a validation study among individuals with suicidal thoughts.
Article in BMC psychiatry, 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
backgroundSuicide is a significant public health challenge in Iran, where cultural and religious factors influence both suicidal behavior and assessment approaches. This study aimed to validate the Persian version of the Brief Suicide Cognitions Scale (B-SCS) among individuals with suicidal thoughts in Iran, addressing a critical gap in culturally appropriate suicide risk assessment instruments.
methodA cross-sectional study was conducted with 162 individuals experiencing suicidal ideation recruited from a psychiatric emergency department in Tehran. Participants completed the Persian B-SCS along with measures of depression, anxiety, hopelessness, and suicidal ideation. Confirmatory factor analysis examined the scale’s factor structure, while reliability was assessed through multiple indices. Convergent validity was evaluated through correlations with related constructs and calculation of Average Variance Extracted (AVE). Measurement invariance across gender was also examined.
resultsConfirmatory factor analysis strongly supported a unidimensional structure with excellent fit indices (χ²(9) = 10.262, p = .330, RMSEA = 0.021, CFI = 0.999, TLI = 0.998) and substantial factor loadings (0.85 − 0.92). The scale demonstrated excellent internal consistency (α = 0.956, ω = 0.957, CR = 0.956) and strong convergent validity, with significant correlations with depression (r = .977), hopelessness (r = .976), anxiety (r = .864), and suicidal ideation (r = .924). The AVE value (0.785) substantially exceeded the recommended threshold. Measurement invariance testing confirmed that the B-SCS functions equivalently across gender groups.
conclusionsThe Persian B-SCS showed strong psychometric properties, including excellent internal consistency, a clear unidimensional structure, and substantial convergent validity, providing robust preliminary support for its potential use in assessing suicide-specific cognitions in Iranian clinical settings.
