Did Cognitive Attentional Syndrome Symptoms Predict Stress- and Trauma-Related Symptoms in the Initial Phase of the COVID-19 Pandemic? Results from a Two-Wave Study on a Sample of Polish Internet Users.

ABSTRACT

BACKGROUND: According to metacognitive theory, Cognitive Attentional Syndrome (CAS) is a transdiagnostic factor and a main mechanism of psychopathology maintenance. The main goal of this study is to examine whether CAS predicted stress- and trauma-related symptomatology in the first months of the COVID-19 pandemic and three months later. METHODS: Initially, 1792 participants were recruited online via social media; the data were collected at two time points. The measures included the Cognitive Attentional Syndrome Questionnaire, the Adjustment Disorder-New Module 20, the International Trauma Questionnaire, and additional measures. RESULTS: Structural equation modeling was conducted in order to determine the relations between the reported stressors, CAS, and symptomatology. At both time points, CAS was a significant mediator between the stressors and symptoms of adjustment disorder. Despite the decrease in the intensity of adjustment disorder symptoms between waves, it was a significant predictor of other psychopathologies at both time points, except for traumatic stress. CONCLUSIONS: The findings confirm the assumption that CAS is a transdiagnostic factor of psychopathology and has a mediating role in the relationship between stressors and adjustment disorder and co-occurring symptomatology. The effect was particularly significant in the initial phase of the pandemic, which was highly stressful for many people.
