Synthesis in BMC psychiatry, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05042050 (Attachment-focused iMAgery Therapy for PSychosis), which is not on this map. Cited by 18 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

backgroundPsychosis can be a sufficiently traumatic event to lead to post-traumatic stress disorder (PTSD). Previous research has focussed on the trauma of first episode psychosis (FEP) and the only review to date of PTSD beyond the first episode period was not systematic and is potentially outdated.

methodsWe searched electronic databases and reference lists using predetermined inclusion criteria to retrieve studies that reported prevalence rates and associated factors of psychosis-related PTSD across all stages of the course of psychosis. Studies were included if they measured PTSD specifically related to the experience of psychosis. Risk of bias was assessed using an adapted version of the Newcastle Ottawa Scale. Results were synthesised narratively.

resultsSix papers met inclusion criteria. Prevalence estimates of psychosis-related PTSD varied from 14 to 47%. Studies either assessed first-episode samples or did not specify the number of episodes experienced. Depression was consistently associated with psychosis-related PTSD. Other potential associations included treatment-related factors, psychosis severity, childhood trauma, and individual psychosocial reactions to trauma.

conclusionsPsychosis-related PTSD is a common problem in people with psychosis. There is a lack of published research on this beyond first episode psychosis. Further research is needed on larger, more generalizable samples. Our results tentatively suggest that prevalence rates of psychosis-related PTSD have not reduced over the past decade despite ambitions to provide trauma-informed care.
