Reliability and validity of the Chinese version of The University of São Paulo Sensory Phenomena Scale in OCD patients.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study aimed to assess the reliability and validity of the Chinese version of The University of São Paulo Sensory Phenomena Scale (USP-SPS).
methodsA total of 256 participants (including 184 patients with obsessive-compulsive disorder (OCD) and 72 healthy controls) completed USP-SPS, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Obsessive-Compulsive Inventory-Revised (OCI-R), Beck Depression Inventory Revised (BDI-II), and Beck Anxiety Inventory (BAI). The internal consistency, test-retest reliability (assessed in a 30-participant subsample over a 1-week interval), the structural validity, and convergent and discriminant validity of the USP-SPS were measured.
resultsExploratory factor analysis yielded a six-factor structure accounting for 59.87% of the total variance, with all items demonstrating salient factor loadings (range = 0.48-0.86). The Chinese version of the USP-SPS severity scale showed moderate correlations with the OCI-R total score (r = 0.35), ordering (r = 0.35), mental neutralisation (r = 0.31), and BAI (r = 0.31), all p < 0.001. Psychometric evaluation demonstrated excellent internal consistency (Cronbach's α = 0.94 for the severity scale in the OCD cohort; KR-20 = 0.80 for the symptom checklist in all participants) and good test-retest reliability (ICC = 0.77) over a 1-week interval.
conclusionThe Chinese version of USP-SPS is a reliable and valid assessment of sensory phenomena in patients with OCD.
