Exploring the Pathways Between Early Auditory Processing, Processing Speed, Social Cognition, and Negative Symptoms on Social Functioning in Individuals at Clinical High Risk for Psychosis: A Structural Equation Modeling Approach.
Article in Biological 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
backgroundSocial functioning difficulties in adolescents and young adults at clinical high risk for psychosis (CHR-P) are among the strongest risk factors for psychosis onset. Recent research in patients with schizophrenia has demonstrated complex relationships between early auditory processing deficits as measured by the mismatch negativity (MMN) response of the auditory event-related potential, neurocognition, social cognition, negative symptoms, and social functioning. However, the interrelationships of these variables and associations with social functioning impairments prior to the onset of the illness are unclear. The present study used a structural equation modeling (SEM) approach to integrate these factors to determine the specific determinants that lead to poor social functioning in CHR-P youth.
methodsA total of 518 CHR-P individuals from the NAPLS2 (North American Prodrome Longitudinal Study) were used to evaluate SEMs with pathways starting from MMN to social functioning. The intervening variables included processing speed, social cognition, and negative symptoms.
resultsA final trimmed model revealed that early auditory processing (MMN) had a direct effect on processing speed, and both processing speed and negative symptoms had direct effects on social functioning. The direct effect from social cognition to social functioning was not significant.
conclusionsOur findings suggest that neurophysiological deficits are associated with social functioning by way of processing speed impairments, which fully accounted for the relationship in CHR-P youths prior to psychosis onset. These results may have implications for early intervention strategies that target early information-processing deficits with the aim of improving social trajectories and limiting psychosis onset in young CHR-P individuals.
