Psychometric evaluation of the Chinese version of the biobehavioural pain and movement questionnaire (BioPMovQ) in elderly CMP patients.
Article in BMC geriatrics, 2025. 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
backgroundAs the population of elderly patients with chronic musculoskeletal pain (CMP) grows, the relationship between pain and exercise behavior has garnered widespread interest. This study aims to localize the BioPMovQ and examine its reliability and validity among elderly CMP patients.
methodsA total of 526 elderly patients with CMP were recruited from the Orthopedics Department of a tertiary hospital in Shanxi Province. After obtaining permission from the original author, the BioPMovQ was translated into Chinese following the Brislin translation principles. This study explored item-level differences through item analysis; it used the Delphi method to analyze content validity, and used exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to explore and verify the potential factor structure of the scale; it also calculated internal consistency reliability and assessed test-retest reliability to evaluate the scale's reliability.
resultsA total of 16 items were retained for project analysis. The content validity index (I-CVI) at the item level of BioPMovQ was 0.857～1.000, and the content validity index (S-CVI) at the questionnaire level was 0.937. In EFA, four common factors were extracted, including disability, self-efficacy for physical activity, movement avoidance behaviours, and self-perceived functional ability, which explained 68.870% of the total variance. The CFA results showed that, χ2/df=2.083, GFI=0.913, NFI=0.902, TLI=0.934, CFI=0.946, IFI=0.947, RMSAE=0.064. The Cronbach's alpha coefficient, split half reliability, and test-retest reliability of the Chinese version of BioPMovQ are 0.844, 0.905, and 0.852, respectively.
conclusionsThe Chinese version of BioPMovQ has good reliability and validity, and can be used to measure the relationship between pain and various factors related to exercise behavior in elderly patients with CMP from a biological behavioral perspective.
