Examining the Role of Item Sequencing of the Interpersonal Needs Questionnaire-15.
Article in Suicide & life-threatening behavior, 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 Interpersonal Needs Questionnaire (INQ) is a 15-item self-report assessment of perceived burdensomeness (PB) and thwarted belongingness (TB), conceptualized as proximal risk factors for suicide ideation (SI). The INQ-15 has strong psychometric properties; however, PB has demonstrated more robust associations with SI than TB.
methodTo assess the possible influence of INQ-15 item sequencing, confirmatory factor analyses (CFAs) were conducted to examine the two-factor structure of the INQ-15 (TB and PB) among participants (N = 600, 50.5% women, 66.8% White, M
resultsAcross all conditions, TB items 9, 11, and 12 raised model-fit concerns. Model fit improved after correlating residuals and removing those items across conditions. The TB-PB correlations were weaker than those reported in prior literature, even after removing those items. The conditions and models did not differ in their associations with TB and PB, or with SI-related variables.
conclusionsRemoving TB items 9, 11, and 12 could optimize the INQ-15 factor structure and improve its concurrent validity; however, replication in additional populations and with other sampling methods is necessary.
