1 · What the graph read from it

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.

2 · The registry

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: Paranoia exists in the general population, both in adults and in children, and is a key feature of schizotypy and schizophrenia-spectrum disorders. Attempts to develop child-appropriate tools to assess childhood suspiciousness and its correlation with developmental psychopathology are underdeveloped but crucial. Aims: This study examines the prevalence and structure of childhood mistrust and its correlations with internalising and externalising problems in non-clinical and clinical samples using a newly validated Italian Social Mistrust Scale (SMS). Methods: Children aged 8-14 years old from a non-clinical (n=242) and a clinical sample with anxiety and/or mood disorder (n=44) were recruited. All children completed the SMS and a standardised battery of tests measuring schizotypal traits, anxiety, depression and internalising/externalising problems. Results: The total Mistrust Score was positively skewed, with 50% of children scoring≤3 points and 15% scoring≥7 points. Factor analyses revealed a three-factor model (ie, General Mistrust, Home Mistrust and School Mistrust) replicating the original English SMS. As expected, childhood mistrust was positively correlated with schizotypal traits, anxiety and depression in the non-clinical sample (r=0.49, 0.42 and 0.54, respectively) and in the clinical sample (r=0.75, 0.51 and 0.85, respectively). Finally, the SMS showed an overall moderate internal reliability (α) in the non-clinical sample (α=0.74), and a good internal reliability in the clinical sample (α=0.83). Conclusions: Consistent with previous studies, childhood mistrust-as measured by the newly translated Italian SMS-exists on a continuum of severity and is associated with higher levels of childhood psychopathology. Exploring social mistrust and suspiciousness in childhood can support clinicians and researchers, and could help develop preventive interventions during early development, particularly for children at risk of specific emotional and behavioural challenges.
