Subjective and physiological reactivity to emotional stressors in somatic symptom disorder (2024)
Gitzen, Harald ; Schmidt, Jennifer ; Martin, Alexandra
Objective: We examined whether autonomic flexibility to experimentally presented stressors is reduced in somatic symptom disorder (SSD) as this would point to reduced vagal control as a proposed indicator of emotion regulation deficits. Method: In this experimental study, the influence of health-related and social stressors on subjective and physiological reactivity was investigated in 29 subjects with SSD without any medical condition SSD(mc−), 33 subjects with SSD with medical condition SSD(mc+) and 32 healthy controls at the age from 18 to 70 years. Self-report and physiological variables were measured before and after/during stressor exposure, using state ratings of symptom intensity, disability, tension and mood, heart rate (HR), and heart rate variability (HRV). Results: Overall, the tension increased and the mood worsened after exposure to stressors compared to pre-exposure. Compared to HC, the two SSD groups showed higher symptom intensity, disability, tension and worse mood. The SSD(mc−) group revealed higher HR than HC (p = .012, d = −0.77). Compared to pre-exposure, symptom impairment increased after social stressor exposure in SSD(mc−) (p < .001, d = 1.36). HRV-root mean square of successive differences (RMSSD) only decreased in HC during exposure (p = .003, d = −1.09), not in the SSD groups. The two SSD groups did not differ in their reactivity to stressors. Conclusion: HRV in SSD, seems to respond less flexibly to stressors, potentially reflecting overall physiological disturbance through reduced parasympathetic influence on HR. Stress reactivity in SSD(mc−) and SSD(mc+) do not seem to differ.
Biofeedback und Neurofeedback (2023)
Martin, Alexandra ; Schmidt, Jennifer
Biofeedback beschreibt eine technikbasierte verhaltenstherapeutische Methode, bei der objektiv messbare Biosignale erfasst und an Patientinnen und Patienten zurückgemeldet werden, um sie zur Selbstregulation von Krankheitssymptomen zu befähigen. Eingesetzt werden kann die Methode bei verschiedenen somatischen und psychischen Störungen, z. B. zur Verringerung muskulärer Verspannungen bei Schmerzstörungen, zur Verengung von Blutgefäßen bei Migräne, zur Steigerung der mit Aufmerksamkeit assoziierten Gehirnaktivität bei ADHS oder zur Verbesserung der allgemeinen Entspannungsfähigkeit. Dieses Buch beschreibt die wissenschaftlichen und psychophysiologischen Hintergründe von Biofeedback und der spezifischen Variante des Neurofeedback, welches auf der Messung der Gehirnaktivität beruht. Neben den angenommenen Wirkmechanismen und vielfältigen Varianten des Biofeedbacks auf Basis unterschiedlicher Biosignale und Körpersysteme, z. B. Herz-Kreislauf-System, Muskelsystem, autonomes und zentrales Nervensystem, wird die zugrunde liegende Messtechnik erklärt. Zusätzlich werden der typische Aufbau von Biofeedback-Sitzungen, die zugehörige Diagnostik sowie Standardprotokolle dargestellt. Das Vorgehen wird anhand von Fallbeispielen verschiedener Störungsbilder veranschaulicht. Erläuterungen zu typischen Anwendungsproblemen sollen ebenso zum Einsatz dieser vielseitigen Methode in der therapeutischen Praxis motivieren, wie der ausführliche Überblick über die aktuelle Evidenz für Biofeedback. Das Buch ist damit eine Bereicherung für therapeutisch arbeitende Personen, die dieses auf objektiven Messungen basierende Verfahren einsetzen wollen, um ihr Behandlungsspektrum zu erweitern.
Appearance-related concerns in individuals with Pathological Skin Picking - A comparison with individuals with dermatological conditions and skin-healthy controls (2023)
Schmidt, Jennifer ; Gallinat, Christina ; Martin, Alexandra
Pathological Skin Picking (PSP) is an excessive behavior which characterizes Skin Picking Disorder. Individuals repeatedly pick their skin and cause skin lesions, but are unable to control the behavior, which can cause severe distress. Visible self-inflicted skin lesions can additionally affect individuals with PSP due to emerging appearance-related concerns. However, these concerns and their role in PSP have hardly been studied, especially not in comparison with individuals with dermatological conditions and skin-healthy controls. The present cross-sectional study (n=453, 83.9% female, 15.9% male, 0.2% diverse) aimed at analyzing appearance-related concerns and mental health outcomes between four groups: Individuals with PSP and dermatological conditions (SP/DC; n=83), PSP without dermatological conditions (SP; n=56), dermatological conditions without PSP (DC; n=176) and skin-healthy controls (SH, n=138). We compared questionnaire data on dysmorphic concerns, appearance-based rejection sensitivity, and body dysmorphic symptoms, as well as PSP-symptoms and mental health outcomes (depression, anxiety, and self-esteem) between groups. The analyses showed a significant multivariate group effect in the appearance-related variables, F(6, 896)=19.92, Wilks’ Λ=0.78, p<.001, and mental health outcomes, F(6, 896)=16.24, Wilks’ Λ=0.81, p<.001. The SP/DC group had the strongest appearance-related concerns and mental health impairments, followed by the SP group, the DC group and the SH group. The SP/DC group and SP group only differed significantly with regard to dysmorphic concerns, but not in other variables. The DC group was less affected but still showed higher dysmorphic concerns and mental health impairments than skin-healthy controls. In contrast to the PSP groups, the other two groups did not exceed clinically relevant cut-off scores. The present study shows that individuals with PSP exhibit strong appearance-related concerns, regardless of the presence or absence of underlying or comorbid dermatological conditions. These findings shed new light on the importance of appearance-related concerns in skin picking disorder and the role of PSP as a potentially overlooked risk factor in dermatological patients. Therefore, appearance-related concerns should be explicitly addressed in dermatological and psychotherapeutic settings. Future studies should also include longitudinal and experimental analyses to more clearly classify the role of appearance-related concerns in the etiology of PSP and skin picking disorder.
