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.

Abstract

Negative symptoms are a strong predictor of poor functional outcome in people with schizophrenia. Unfortunately there are few effective interventions for either negative symptoms or functional outcome, despite the identification of potential mechanisms. Recent research, however, has elucidated a new potential mechanism for negative symptoms and poor functional outcome: defeatist performance beliefs (DPB), or negative thoughts about one's ability to successfully perform goal-directed behavior that can prevent behavior initiation and engagement. We conducted 2 meta-analyses examining the relationship between DPB and both negative symptoms (n = 10 studies) and functional outcome (n = 8 studies) in people with schizophrenia. We found a small effect size for the relationship between DPB and negative symptoms, regardless of how negative symptoms were measured. We also found a small effect size for the relationship between DPB and functional outcome, which was significantly moderated by the method of assessing DPB and moderated by the sex composition of the study at a trend level. These findings highlight the potential of targeting DPB in psychosocial interventions for both negative symptoms and functional outcome.
