Revisiting the Defeatist Performance Belief Scale in Adults With Schizophrenia and Youth at Clinical High-Risk for Psychosis: A Comprehensive Psychometric Analysis.

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 hypothesisIn accordance with the Cognitive Model of Negative Symptoms, defeatist performance beliefs (DPBs) are an important psychosocial mechanism of negative symptoms in schizophrenia-spectrum groups. DPBs are also mediators of negative symptom improvement in clinical trials. Despite the clinical significance of DPBs and their inclusion as a mechanism of change measure in clinical trials, the psychometric properties of the DPB scale have not been examined in any schizophrenia-spectrum group. STUDY
designThis study evaluated the factor structure, reliability, and validity of the DPB scale in 943 schizophrenia and 250 clinical high-risk for psychosis (CHR) participants from multiple US sites. Confirmatory factor analyses tested competing factor structures: a unidimensional model-consistent with how DPBs are currently assessed-and multifactorial models with up to 4 factors identified with exploratory factor analyses. STUDY
resultsModels with 3 and 4 factors provided superior fit compared to the unidimensional model, with an advantage for the 3-factor model. The 3-factor model, consisting of Overvaluing Success, Overvaluing Failure, and Overvaluing Social Evaluation factors, demonstrated good replicability, temporal stability, and measurement invariance in schizophrenia and CHR samples. Convergent validity was demonstrated via significant correlations with negative symptoms and functioning, but limited associations were present with neurocognition. Discriminant validity was supported by low correlations with positive symptoms.
conclusionsFindings support the validity and reliability of the 3-factor structure of the DPB scale across phases of psychosis. Use of a 3-factor structure may clarify the most critical DPB targets for negative symptom treatment and early prevention and intervention.
