Abstract

The current study examined factorial invariance of the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R) and the Depression Anxiety Stress Scales-21 (DASS-21) using a convenience sample of 434 adults surveyed though Amazon Mechanical Turk. Participants were sorted into two groups based on their score on the Autism-Spectrum Quotient. Results indicated that the CESD-R did not demonstrate configural invariance. The DASS-21 demonstrated evidence of scalar invariance, indicating cross-group equality in factor loadings and factor intercepts. Findings suggest that the DASS-21 measures symptoms of depression, anxiety, and stress consistently across individuals with high and low levels of ASD-related traits, whereas the CESD-R may not be valid when assessing symptoms of depression in those with a high level of ASD-related traits.
