Development and validation of the short form of the Parker personality measure among Chinese college students.

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
Objective: Current diagnostic frameworks for pathological personality are shifting from categorical to dimensional models. While the Personality Inventory for DSM-5 represents the most extensively validated dimensional measure across Western and Eastern cultures, its length limits practical utility. This study developed the Parker Personality Measure Short Form (PERM-SF) to facilitate efficient screening of pathological personality traits. Methods: Two samples of college students (Sample 1: Results: Thirty-eight of the 92 items of PERM were deleted due to low factor loadings or high cross loadings, resulting in a five-factor model consisting of 54 items (F1: Dissociality, F2: Self-doubt-Detachment, F3: Disinhibition-Negative affectivity, F4: Anankastia, F5: Borderline pattern). All factors demonstrated good internal consistency (McDonald's ω = 0.834-0.932). Longitudinal measurement invariance held at strict level (ΔCFI ≤ 0.001, ΔRMSEA ≤ 0.001) and two-way random-effects ICCs ranged from 0.488 to 0.759. Validity analyses revealed significant weak-to-moderate correlations with the Symptom Checklist-90 and established discriminant validity for all factor pairs, as supported by the Heterotrait-Monotrait Ratio test. Conclusion: The PERM-SF exhibits adequate preliminary psychometric properties for rapid assessment of pathological personality dimensions, supporting its utility for research and screening applications at least among Chinese young adults.
