Translation, cross-cultural adaptation, and psychometric evaluation of the Chinese version of the persistent somatic symptom stigma scale for healthcare professionals (PSSS-HCP-C): a cross-sectional study.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPersistent somatic symptoms (PSS) refer to a group of clinical syndromes characterized by recurrent or persistent bodily discomfort lasting ≥ 3 months, such as chronic fatigue, refractory dizziness, and persistent pain. Patients with PSS often face stigma due to the absence of a clear organic etiology, which can exacerbate psychological distress, reduce treatment adherence, and hinder timely medical help-seeking. Healthcare professionals’ biased perceptions or othering toward PSS may further impede accurate diagnosis and optimal care. To date, no standardized tool is available in China to measure stigma among healthcare professionals toward PSS.
aimThis study aimed to translate the Persistent Somatic Symptom Stigma Scale for Healthcare Professionals (PSSS-HCP) into Chinese (PSSS-HCP-C), conduct cross-cultural adaptation, and examine its reliability and validity in a sample of Chinese healthcare professionals.
methodsFollowing Brislin’s translation model, the original PSSS-HCP was forward-translated, synthesized, back-translated, reviewed by an expert committee, and pretested for cultural adaptation. A convenience sample of 282 healthcare professionals was recruited from March to April 2025 for psychometric testing, with 30 participants completing the retest after two weeks. Content validity was assessed by the content validity index. Construct validity was examined using exploratory factor analysis. Reliability was evaluated by Cronbach’s α, split-half reliability, and test-retest reliability.
resultsThe Chinese version of the PSSS-HCP comprised 13 items across three dimensions: othering, uneasiness in interaction, and non-disclosure. The item-level content validity index (CVI) ranged from 0.80 to 1.00, with a scale-level CVI of 0.946. Exploratory factor analysis (EFA) extracted three common factors, explaining 66.692% of the total variance, with factor loadings between 0.743 and 0.885. The overall Cronbach’s α was 0.867, with subscale α coefficients ranging from 0.817 to 0.872. The split-half reliability was 0.798, and the test-retest reliability was 0.897.
conclusionsThe Chinese version of the PSSS-HCP demonstrated satisfactory reliability and validity and can be used to assess healthcare professionals’ stigma toward patients with PSS in China. This tool provides a robust measurement basis for developing interventions to reduce stigma, enhance clinical attitudes, and inform policy-making in PSS management.
