Paternal Broader Autism Phenotype and Adolescent Avoidant Attachment as Independent Predictors of Negative Symptoms in Early Psychosis.
Article in Brain and 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
introductionFamilial neurodevelopmental traits and early relational experiences are increasingly recognized as contributors to heterogeneity in psychosis outcomes. However, little is known about how parental broader autism phenotype (BAP) and adolescent attachment jointly relate to symptom severity and treatment adherence in early-onset psychosis.
methodsThis cross-sectional study enrolled 42 adolescents (aged 12-17 years; 88.1% schizophrenia, 11.9% schizoaffective disorder) and their biological parents. Parental BAP was assessed using the Autism Spectrum Quotient-Revised (AQ-R), adolescent attachment with the Psychosis Attachment Measure (PAM), symptom severity with the Scale for the Assessment of Positive/Negative Symptoms (SAPS/SANS), and parent-reported medication adherence with the MARS-5. Hierarchical multiple regression analyses were conducted to test the hypotheses.
resultsParental BAP did not predict adolescent attachment. However, the model predicting negative symptoms was significant (R
conclusionPaternal autistic traits and adolescent avoidant attachment may represent independent developmental and relational factors associated with negative symptoms in early psychosis. These findings underscore the need for family-informed assessment and intervention strategies, particularly targeting paternal characteristics and attachment dynamics. Given the modest sample size and cross-sectional design, replication in larger longitudinal cohorts is warranted.
