Abstract
BackgroundAnxiety sensitivity (AS) is a trait-like predisposing factor for the prevalence of anxiety in patients diagnosed with breast cancer. The Anxiety Sensitivity Index-3 (ASI-3) has been widely used in both general and clinical samples for measuring AS. However, the data about its psychometric properties in women with breast cancer are deficient. In addition, there is no evidence proving the measure equivalence of ASI-3 across sociodemographic variables in the specific sample. Thus, the present study examined the psychometric properties and conducted measure equivalence testing of ASI-3 in Chinese women diagnosed with breast cancer.MethodsThis study included 815 Chinese women diagnosed with breast cancer. Single group confirmatory factor analysis (CFA) was administrated to detect the factorial validity of ASI-3, and multigroup CFAs were conducted to test the measurement equivalence of ASI-3 across various sociodemographic variables. The reliability of ASI-3 was tested by Cronbach’s alpha coefficient, Guttman split-half coefficient, McDonald’s omega coefficient, and test–retest coefficient. The standardized factor loadings, construct reliability, and the average variance extracted of factors were used to measure the construct validity of ASI-3, and the partial correlations were conducted to examine the criterion-related validity of ASI-3.ResultsThe ASI-3 had satisfactory reliability and validity in Chinese women diagnosed with breast cancer; three-factor model fitted the data well in CFA and reached partial strict invariances across age, education, and residence groups.ConclusionThis study explored the psychometric properties and measurement invariance across sociodemographic variables of ASI-3 in Chinese women diagnosed with breast cancer. Our results not only proved that the ASI-3 is an appropriate instrument for measuring AS but also deepened the understanding of ASI-3 in Chinese women with malignancy.
Highlights
Nowadays, breast cancer is the most common cancer and becomes a leading cause of cancer-related death in Chinese women (Fan et al, 2014)
In current study, we examined the invariance of factor structure and different performance on Anxiety Sensitivity Index-3 (ASI-3) across different demographic variables in Chinese women diagnosed with breast cancer
A sample of 815 female patients diagnosed with breast cancer from two hospitals in Changsha participated in this study
Summary
Breast cancer is the most common cancer and becomes a leading cause of cancer-related death in Chinese women (Fan et al, 2014). Many studies have proved that anxiety severity was correlated with the levels of anxiety sensitivity (AS) and AS is a trait-like predisposing factor of anxiety (Olatunji and Wolitzky-Taylor, 2009; Knapp et al, 2016; Mohammadkhani et al, 2016). There is evidence suggesting that women with breast cancer showed more health anxiety, which is strongly associated with the cognitive AS (Jones et al, 2014). AS is a specific vulnerability trait for the prevalence of anxiety in patients diagnosed with breast cancer. Anxiety sensitivity (AS) is a trait-like predisposing factor for the prevalence of anxiety in patients diagnosed with breast cancer. The present study examined the psychometric properties and conducted measure equivalence testing of ASI-3 in Chinese women diagnosed with breast cancer
