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

backgroundFeelings of emptiness are commonly reported as deeply distressing experiences. Despite established relationships between emptiness and many mental health difficulties, alongside self-harm and suicide, further study into this phenomenon has been restricted by vague definition and clinical measures with limited utility. Recently the first definition validated by individuals with lived experience of emptiness has been conceptualised, providing an opportunity to create a new measure of emptiness.

aimsThis study aimed to psychometrically evaluate the 31-item Psychological Emptiness Scale (PES), identifying redundancy, and thus creating a psychometrically robust scale with optimised clinical utility.

methodUtilising an online survey design, 768 participants completed the 31 items of the initial PES alongside other measures of mental health. Exploratory factor analysis was conducted, and item response theory employed to identify item redundancy and reduce test burden. Expert clinicians provided ratings of each item's clinical relevance and, combined with the psychometric analysis, led to the removal of a number of items. Confirmatory factor analysis was then undertaken. Reliability including test-retest, validity and sensitivity of the measure were evaluated.

resultsA two-factor structure encompassing 'nothingness' and 'detachment' was identified, and found to have acceptable fit. The resulting 19-item PES was found to have internal consistency (

conclusionsThis study demonstrated strong psychometric properties of the PES. The PES has potential to support research into the role of emptiness in psychological distress and treatment in clinical practice.
