Development and validation of the Chinese version of the adult sedentary behavior reduction intention questionnaire based on the theory of planned behavior.

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
promThe Chinese version of the Adult Sedentary Behavior Reduction Intention Questionnaire, a 16-item self-reported tool based on the Theory of Planned Behavior (TPB), was developed to assess adults' intentions to reduce sedentary behavior. MEASUREMENT PROPERTY: Internal consistency is used to measure the reliability of the questionnaire, while content and structural validity are studied to assess its validity.
designA mixed-methods exploratory sequential design with two phases. SAMPLE: Adults aged over 18 years diagnosed with coronary heart disease, with a total daily sedentary time exceeding 6 h, normal cognitive function, and willingness to participate in the study were included.
methodsThe study was conducted in two phases. In Phase 1, an initial item pool was developed through a literature review and refined using two rounds of Delphi expert consultation. Expert positivity, authority levels (Cr), coefficients of variation (CV), and Kendall's W coefficient were calculated to assess representativeness, credibility, and consensus. A pilot study evaluated face validity and finalized the scale. In Phase 2, a cross-sectional study involving 316 participants was conducted to assess psychometric properties. Reliability was evaluated using Cronbach's α and split-half reliability, while content validity was assessed using the content validity index (I-CVI). Construct validity was examined through confirmatory factor analysis (CFA).
resultsPhase 1 resulted in a preliminary questionnaire with four dimensions and 16 items. Sixteen experts completed two rounds of Delphi consultation, with high response rates (85% and 94.1%) and authority levels (Cr = 0.88 and 0.91). Consensus was strong (CV = 0.05 ~ 0.23; Kendall's W = 0.338 and 0.382, p < 0.001). Phase 2 validation showed a Cronbach's α of 0.967, with individual dimensions ranging from 0.911 to 0.950. I-CVI ranged from 0.813 to 1. The adjusted model indices met the fitting criteria.
conclusionsThe developed questionnaire is a reliable and valid tool for assessing Chinese adults' intentions to reduce sedentary behavior. Grounded in TPB, it provides a theoretical foundation for future intervention studies aimed at addressing sedentary lifestyles.
