Predicting negative symptoms: a novel scale for assessing anticipatory cognitive mechanisms in psychosis.
Article in Annals of general 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
introdcutionNegative symptoms are a central feature of the schizophrenia spectrum and also appear subclinically in healthy individuals, being associated with poor functional outcomes. Although clinician-rated measures remain the gold standard, self-report tools offer efficiency and a direct insight into subjective experiences.
objectiveThis study presents the development and validation of the Negative Symptoms Anticipation Scale (NSAS), a novel self-report instrument designed to assess anticipatory cognitions related to negative symptoms.
methodIn a pilot study, an initial 28-item version was refined to a final 16-item version organized into three factors: [Kirkpatrick B, Fenton WS, Carpenter WT, Marder SR 1;32(2):214-9:2006] Anticipation of Social Difficulties [Sicras-Mainar A, Maurino J, Ruiz-Beato E, Navarro-Artieda R 14(1):225:2014], Anticipation of Relationship Difficulties, and [Stahl SM, Buckley PF 115(1):4-11:2007] Anticipation of Low Energy in Daily Activities.
resultsIn a community sample (N = 3,237), the NSAS demonstrated excellent internal consistency (α = 0.927; ω = 0.926; α ordinal = 0.949) and test-retest reliability, as well as a robust factor structure confirmed via confirmatory exploratory analysis (CFI ≥ 0.997; RMSEA ≤ 0.025). Factorial invariance was established across gender and age, and ROC curve analysis indicated outstanding predictive ability for identifying individuals at risk for transitioning to psychosis (AUC = 0.905). Convergent validity was supported by moderate to high correlations with established measures of negative symptoms and negative schizotypy. Hierarchical linear regression showed that, when controlling for social anhedonia and depression, the anticipatory component contributed approximately 7-25% of the variance in negative symptoms.
conclusionsThese findings support the validity of the NSAS and suggest that its application could facilitate early detection and intervention in psychosis.
