The low discriminant validity that some of the established instruments for the assessment of anxiety exhibit regarding depressive symptoms has presented to be a challenge. In this context, the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) must be mentioned, which is used almost exclusively to assess state and trait anxiety. Newer findings suggest that the STAI also assesses depressive symptoms, aside from anxiety (Kennedy, Schwab, Morris, & Beldia, 2001; Knowles & Olatunji, 2020). Both constructs appear to share a component of negative affect (e.g. Anderson & Hope, 2008; Balon, 2005; Bieling, Antony, & Swinson, 1998; Caci, Baylé, Dossios, Robert, & Boyer, 2003). In the context of clinical research and practice, one might not only be interested in assessing negative affectivity, but in assessing distinct aspects of anxiety. Therefore, we are in need of an instrument that validly assesses anxiety, separate from depressive symptoms. In contrast to other questionnaires, the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA; Ree, French, MacLeod, & Locke, 2008) aims to do just that – measuring anxiety without measuring negative affectivity. In the present study we aimed to develop a German version of the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA) and evaluate the psychometric properties. Associations of cognitive and somatic anxiety with other measures of anxiety, depression, and stress, elucidating possible underlying functional connections, were also examined. Other measures beside the STICSA were the State-Trait Anxiety Inventory (STAI, Spielberger, 1981; German version by Laux, Glanzmann, Schaffner & Spielberger, 1983), the Depression Anxiety Stress Scales (DASS-21, Henry & Crawford, 2005; German version by Nilges & Essau, 2015), and the Beck Depression Inventory II (BDI, Beck, Steer, & Brown, 1996; German version by Kühner et al., 2007). Data from 301 participants was collected online for sample 1. Data from 303 participants was additionally collected for sample 2. Dynamic connections between somatic and cognitive anxiety, other measures of anxiety, depression, and stress, were analyzed using a network approach. Psychometric analyses were conducted using exploratory and confirmatory factor analyses. ---------- REFERENCES - Anderson, E. R., & Hope, D. A. (2008).
