Key result
The German version of the Florida Shock Anxiety Scale demonstrated good internal consistency and convergent validity in 138 patients with defibrillators, best represented by a bi-factorial model.
Why the study?
Many patients with cardioverter defibrillators develop anxiety disorders, and while the English Florida Shock Anxiety Scale is used to diagnose these symptoms, the quality of the German version required investigation.
Cross-Sectional (n=138)
The German version of the Florida Shock Anxiety Scale is a valid and reliable tool for assessing shock-induced anxiety in patients with cardioverter defibrillators.
May aid shock anxiety screening in German-speaking ICD patients; supports FSAS validity but leaves broader adoption open.
Cardiovascular diseases are among the leading causes of death, worldwide.To protect those vulnerable to cardiac arrest, defibrillators performing reanimation by automatic discharge are implanted. Due to the high pain intensity of such a procedure, many patients develop anxiety disorders. To diagnose the fear-relevant symptoms, the English version of the Florida Shock Anxiety Scale (FSAS) is used. The present study investigates the quality of the German version of the FSAS using a confirmatory factor analysis. Therefore, a sample of N = 138 participants (n = 38 female and n = 100 male; age: M = 60.99, SD = 11.58) with implanted or wearable cardioverter defibrillators was examined. Similar to the English version, the most suitable model includes the two factors ‘consequence’ and ‘trigger stimulus’. Although, in our investigation, it is not a second order model but a bi-factorial model which reaches the best fit. Both the internal consistency and the convergent validity were checked and showed sufficiently good values. In summary, the German version of the FSAS may also be recommended for the diagnosis of shock-induced anxiety disorder.

Ritzka et al. (2019) conducted a cross-sectional in Implanted or wearable cardioverter defibrillators (n=138). German version of the Florida Shock Anxiety Scale (FSAS) was evaluated on Factorial structure, internal consistency, and convergent validity. The German version of the Florida Shock Anxiety Scale demonstrated good internal consistency and convergent validity in 138 patients with defibrillators, best represented by a bi-factorial model.
