Psychometric properties of the Suicidal Ideation Attributes Scale (SIDAS) in a longitudinal sample of people experiencing non-affective psychosis.
Article in BMC psychiatry, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.
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
backgroundSuicidal ideation is a key precursor for suicide attempts and suicide deaths. Performing routine screening of suicide precursors can help identify people who are at high risk of death by suicide. This is, arguably, an important suicide prevention effort. The aim of this study was to assess the validity, reliability, and factor structure of the Suicidal Ideation Attributes Scale (SIDAS) in a three-month longitudinal study with people with a diagnosis of schizophrenia or non-affective psychosis and experiences of suicidal ideation and/or behaviours. It was predicted that the SIDAS would have high internal consistency, test-retest reliability, convergent, discriminant and construct validity.
methodsNinety-nine participants experiencing psychosis completed the SIDAS at baseline and 89 participants completed it 3 months later. Additionally, participants completed a demographic questionnaire, the Beck Scale for Suicide Ideation, the Beck Hopelessness Scale, and the Defeat and Entrapment Scales. The internal consistency, test-retest reliability, convergent validity, and discriminant validity of the SIDAS were investigated in comparison to other constructs. Factor analysis was performed to examine the factor structure of the scale.
resultsPrincipal component analysis yielded a theoretically coherent one-dimensional factor structure of SIDAS, suggesting good construct validity (PCA = .71). The SIDAS had high internal consistency (α = .89) and good test-retest reliability (α = .73). It was highly correlated with other self-report measures, including the Beck Scale for Suicide Ideation, Beck Hopelessness Scale, Defeat and Entrapment scales, indicating excellent construct validity.
conclusionThe SIDAS is a valid and reliable self-report instrument for assessing the severity of suicidal ideation in a population of people with a diagnosis of schizophrenia or non-affective psychosis. Further research should test the psychometric properties of the scale in individuals experiencing different mental health problems in cross-cultural settings, in order to establish its broader validity, reliability, and clinical utility.
