The role of trauma, attachment, dissociation, and alexithymia in pathways to negative symptoms in psychosis.

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
objectivesEmerging models of trauma and psychosis highlight the role of attachment, dissociation, and emotion regulation processes in pathways to positive symptoms, yet little is known about the relevance of these processes to negative symptoms. The primary aim of this study was to examine trauma, attachment, dissociation, and alexithymia as predictors of negative symptoms in psychosis. A secondary, exploratory aim was to delineate pathways by which trauma may lead to negative symptoms (via attachment, dissociative or alexithymic processes).
methodThis was a cross-sectional study of people attending mental health services for a psychosis-related diagnosis (N = 71). Measures of trauma, negative symptoms, attachment, alexithymia, dissociation, and depression were completed.
resultsRegression analyses indicated that recurrent trauma, disorganized attachment, difficulty identifying feelings (DIF), and depression accounted for a significant portion of the variance in negative symptoms, though only DIF and depression were significant independent predictors. Subsequent serial mediation analyses indicated that recurrent trauma exerted its influence on negative symptoms through a sequence of disorganized attachment and DIF, while controlling for depression. As avoidant attachment was not associated with trauma and dissociation was not associated with total negative symptoms, hypothesized models related to these variables were not examined.
conclusionsThese exploratory findings highlight the relevance of trauma-related variables in our formulation and treatment of negative symptoms. Future research should focus on replication studies with larger clinical samples and longitudinal designs to establish causality.
