Development and Validation of a Simplified Chinese Version and a Face-Scale Version of the Oxford Shoulder Score: A 2-Center Prospective Study

Translation and validation of the simplified Chinese version of the Chronic Pain Coping Inventory-42

BACKGROUND

The Chronic Pain Coping Inventory-42(CPCI-42) is mainly used for chronic pain management project, its original version is written in English and has been widely used in western countries. Therefore, the purpose of our study is to apply the CPCI-42 to Chinese patients and evaluate its responsiveness, reliability, and validity for Chinese patients with lumbar disc herniation (LDH).

METHODS

Translation and adaptation were carried out in accordance with the guidelines of the American Academy of Orthopedic Surgeons Outcome Committee. A total of 133 patients who were diagnosed with LDH were included in this study. Psychometric evaluations were then performed and included score distribution, internal consistency, test-retest reliability, construct validity, and responsiveness.

RESULTS

CPCI-42 is well adapted to the assessment of the cognitive and behavioral strategies of patients with LDH, and the scores of score distribution, internal consistency, test-retest reliability, construct validity, and responsiveness are excellent. Forward and reverse translation of the CPCI-42 to English from Chinese worked smoothly.

CONCLUSION

It is applicable to the assessment of quality of life of the cognitive and behavioral strategies of patients with LDH, and the scores of all indicators are excellent.

Development of a simplified version of the smoking rationalization belief scale for Chinese male smokers

Objective

The goal of this study was to simplify the smoking rationalization belief (SRB) scale among Chinese male smokers and provide a convenient measuring tool with good reliability and validity to promote the assessment and further intervention of SRB among smokers.

Methods

Through purposive sampling, a questionnaire survey was conducted among adult male smokers in three districts in Shanghai, and 1,307 valid questionnaires were collected. Exploratory factor analysis was used to analyze the simplified scale, and Pearson correlation analysis, multiple linear regression, and Cronbach's α were used to test the reliability and validity of the simplified scale.

Results

The SRB scale was simplified from 26 items to 8 items and had good overall reliability (Cronbach's α = 0.757). There was a strong correlation between the simplified scale and the original scale (P < 0.001, r = 0.911), and the scores of SRB measured by the two scales were both negatively associated with a willingness to quit smoking (P < 0.001), which reflected the practical effectiveness of the simplified version.

Conclusion

The simplified version of the SRB scale showed good reliability and validity among Chinese smokers, which facilitates smoking cessation-related research and practice.
