Key result
The Chinese version scale of the Fear of Activity demonstrated good reliability (internal consistency 0.74, test-retest 0.82) and validity (content validity index 0.90) in patients with CAD.
Why the study?
The study was conducted to translate and evaluate the psychometric properties of a Chinese version scale to measure fear of activity in patients with coronary artery disease.
Cross-Sectional (n=275)
No
The Chinese version of the Fear of Activity scale is a reliable and valid 21-item instrument for assessing fear of activity in patients with coronary artery disease.
Provides initial support for Chinese Fear of Activity scale in CAD; leaves clinical adoption open pending prospective validation.
AIM: To translate and test the psychometric properties of a Chinese version scale to measure the Fear of Activity in patients with Coronary Artery Disease. DESIGN: A cross-sectional design. METHODS: The translation of the scale to measure Fear of Activity in Patients with Coronary Artery Disease included three steps, forward-back translation, expert discussion and pilot survey. The internal consistency and test-retest reliability were used to assess the reliability of the Chinese version scale of the Fear of Activity. Content, construct, criterion, and known-group validity of the scale were also evaluated. DATA SOURCES: A total of 275 patients with Coronary Artery Disease were recruited from a university-affiliated hospital in Guangzhou, southern China. RESULTS: The overall content validity index of the Chinese version scale of the Fear of Activity in Patients with Coronary Artery Disease was 0.90. Principal component analyses extracted four factors with a cumulative variance contribution of 57.5%. There is a strong correlation (r = 0.83) between this scale and Tampa Scale for Kinesiophobia Heart. The total scores of the Chinese version scale of the Fear of Activity in female patients were higher than those in male patients with Coronary Artery Disease, indicating that the scale was able to distinguish the differences between low and high score groups. The Internal consistency and test-retest reliability coefficients of the scale were 0.74 and 0.82, respectively. CONCLUSION: The Chinese version scale of the Fear of Activity in Patients with Coronary Artery Disease, which consists of 21 items with four dimensions, is a reliable and valid instrument to evaluate the fear of activity in patients with Coronary Artery Disease. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The Chinese version scale of the Fear of Activity in Patients with Coronary Artery Disease can be used to assess the levels of fear of activity in patients with Coronary Artery Disease and explores the factors that influence fear of activity in the population. IMPACT: This study translates and confirms the psychometric properties of the Chinese version scale of the Fear of Activity in Patients with Coronary Artery Disease in China. It is useful in both research and clinical fields to explore the fear of activity and its associated factors in patients with Coronary Artery Disease. REPORTING METHOD: The study design followed the guideline of Strengthening the Reporting of Observational Studies in Epidemiology statement. PATIENT OR PUBLIC CONTRIBUTION: Patients in a university-affiliated hospital participated in this study and contributed to data collection.

Chen et al. (2023) conducted a cross-sectional in Coronary Artery Disease (n=275). Chinese version scale of the Fear of Activity was evaluated on Psychometric properties including validity and reliability. The Chinese version scale of the Fear of Activity demonstrated good reliability (internal consistency 0.74, test-retest 0.82) and validity (content validity index 0.90) in patients with CAD.
