Stress-associated symptoms and disorders: A transdiagnostic comparison

The ICD-11 features a new group of disorders specifically associated with stress, which are interlinked by various symptoms, such as intrusive memory symptoms. Although research interest in these new ICD-11 diagnoses is growing rapidly, so far, no studies have systematically investigated the transdiagnostic distribution of stress-associated symptoms in these disorders. In the present study, 447 individuals completed a series of online questionnaires, which measured various stress-associated symptoms, e.g., flashbacks, preoccupation or yearning. Findings showed that the majority of correlations between the measured psychopathological constructs was between 0.30 and 0.60. Furthermore, with regard to specific diagnostic groups, a complex variation of stress-associated symptoms was observed, with preoccupation as a predominant symptom in all disorders. Results demonstrate that stress-associated symptoms are inherently interconnected yet possess an individual variation in different disorders. Furthermore, findings illustrate that preoccupation represents a major feature in all stress-associated disorders.
