The Negative Symptom Inventory-Psychosis Risk (NSI-PR): Psychometric Validation of the Final 11-Item Version.
Article in Schizophrenia bulletin, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
background and hypothesesThe lack of psychometrically validated assessment tools designed specifically to assess negative symptoms in individuals at clinical high risk (CHR) for psychosis represents a significant barrier to the early identification and prevention of psychosis. To address this need, the Negative Symptom Inventory-Psychosis Risk (NSI-PR) was developed based on the iterative, data-driven approach recommended by the National Institute of Mental Health consensus conference on negative symptoms. STUDY
designThis manuscript reports the results of the second study phase that psychometrically validates the final 11-item version of the scale in data collected across 3 sites. A total of 222 participants (144 CHR and 78 clinical help-seeking controls) completed the NSI-PR, 1 week of ecological momentary assessment (EMA), and additional convergent and discriminant validity measures. STUDY
resultsStructural analyses replicated the previously reported strong fit for the 5-factor (anhedonia, avolition, asociality, alogia, and blunted affect) and hierarchical structures (2 super-ordinate dimensions and 5 lower-level domains). The 5 domains and 2 dimensions generally demonstrated good internal consistency, temporal stability, and interrater reliability. Convergent validity was demonstrated in relation to the 16-item beta version of the NSI-PR, Structured Interview for Psychosis-risk Syndromes negative subscale, Global Functioning Scale social and role, and EMA measures. Discriminant validity was supported by low correlations with positive, disorganized, and general psychiatric symptoms.
conclusionsFindings indicate the final 11-item version of the NSI-PR has sound psychometric properties. The scale, which is designed specifically for CHR individuals, is brief and appropriate for use in research and clinical contexts. Accompanying training materials have been developed to support its use in multisite trials.
