Abstract
Purpose: Anxiety sensitivity (AS) refers to fear of anxiety-related sensory arousal and has been revealed to be associated with increased psychological distress and mental problems. Although Anxiety Sensitivity Index-3 (ASI-3) has been confirmed to be effective in evaluating this construct, whether it is consistently applicable in college students is still elusive. The present study aimed to examine the psychometric properties and measurement invariance of Chinese version of ASI-3 (C-ASI-3) among college students experiencing campus lockdown due to novel coronavirus disease 2019 (COVID-19) pandemic.
Methods: A total of 1532 Chinese college students (397, 25.9% males) aged between 16 and 25 were included in this study. Confirmatory factor analysis (CFA) was used to verify the factor structure of C-ASI-3. Multi-group CFA was conducted for analysis of measurement invariance with regard to gender. McDonald's omega values were computed for examination of scale reliability. For criterion, convergent, and divergent validity, average variance extracted (AVE) values for C-ASI-3 subscales, difference between square root of AVE for each factor and inter-factor correlation, as well as pearson correlation and partial correlation between the C-ASI-3 and other three scales, including the Depression, Anxiety, and Stress Scale-21 (DASS-21), the State-Trait Anxiety Inventory (STAI), and the Fear of COVID-19 scale (FCV-19 S) were evaluated.
Results: The C-ASI-3 presented a three-factor scale structure with fit indices being as follows: χ2/df = 11.590, CFI = 0.938, RMSEA = 0.083, SRMR = 0.042. Strict measurement invariance was reached across gender. Regarding convergent validity, the C-ASI-3 had a high correlation with the DASS-21 (r = 0.597, p < 0.01) and the STAI (r = 0.504, p < 0.01). All AVE values for C-ASI-3 subscales were above 0.5. In terms of divergent validity, the C-ASI-3 had medium correlation with the FCV-19 S (r = 0.360, p < 0.01). Square of root of AVE for each factor was higher that inter-factor correlation. McDonald's omega values of the three dimensions ranged from 0.898 ~ 0.958.
Conclusion: The C-ASI-3 has acceptable psychometric properties among college students. College students with different gender have consistent understanding on the scale construct.
期刊介绍：
Social Psychiatry and Psychiatric Epidemiology is intended to provide a medium for the prompt publication of scientific contributions concerned with all aspects of the epidemiology of psychiatric disorders - social, biological and genetic.
In addition, the journal has a particular focus on the effects of social conditions upon behaviour and the relationship between psychiatric disorders and the social environment. Contributions may be of a clinical nature provided they relate to social issues, or they may deal with specialised investigations in the fields of social psychology, sociology, anthropology, epidemiology, health service research, health economies or public mental health. We will publish papers on cross-cultural and trans-cultural themes. We do not publish case studies or small case series. While we will publish studies of reliability and validity of new instruments of interest to our readership, we will not publish articles reporting on the performance of established instruments in translation.
Both original work and review articles may be submitted.
