Delineating the Transmission of Subthreshold Psychosis Symptoms Across Generations: The Philadelphia Family Neurodevelopmental Cohort.
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 1 paper.
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 hypothesisIntergenerational factors are implicated in development of schizophrenia spectrum disorders. Studying psychosis spectrum (PS) symptoms dimensionally in a longitudinal, prospective intergenerational cohort can provide crucial insight into risk pathways. Thus, we established the Philadelphia Family Neurodevelopmental Cohort (PFNC), an intergenerational study that follows Philadelphia Neurodevelopmental Cohort (PNC) participants as they transition to parenthood, along with their offspring. This first report describes the creation of the PFNC, followed by an examination of longitudinal associations between risk factors assessed in adolescence (PS symptoms, cognition, and traumatic life events) and mental health and resilience outcomes in parenthood. STUDY
designSince the PNC was accrued (2009-2011; ages 8-21 years), many participants have become parents. As an initial step in the development of PFNC, participants completed a virtual self-report battery to assess parental status, family structure, current mental health symptoms, and parent-relevant risk and resilience factors. STUDY
resultsThe current PFNC includes 456 PNC participants with 740 offspring, consisting primarily of biological mothers (female = 84%; Black = 65%; mean parent age = 28.38 years, SD = 3.40; mean offspring age = 4.01 years, SD = 3.36). Findings revealed adolescent PS symptoms and traumatic events are associated with PS symptoms in parenthood. Adolescent PS symptoms were also linked to higher levels of household chaos approximately 12 years later.
conclusionDespite the growing recognition of the intergenerational transmission of neuropsychiatric risk, there is limited research examining intergenerational risk factors in the context of PS symptoms. The PFNC represents a critical next step toward advancing our understanding of intergenerational pathways contributing to PS risk.
