  abstract  = {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.},

  abstract  = {Biofeedback beschreibt eine technikbasierte verhaltenstherapeutische Methode, bei der objektiv messbare Biosignale erfasst und an Patientinnen und Patienten zur{\"u}ckgemeldet werden, um sie zur Selbstregulation von Krankheitssymptomen zu bef{\"a}higen. Eingesetzt werden kann die Methode bei verschiedenen somatischen und psychischen St{\"o}rungen, z. B. zur Verringerung muskul{\"a}rer Verspannungen bei Schmerzst{\"o}rungen, zur Verengung von Blutgef{\"a}ßen bei Migr{\"a}ne, zur Steigerung der mit Aufmerksamkeit assoziierten Gehirnaktivit{\"a}t bei ADHS oder zur Verbesserung der allgemeinen Entspannungsf{\"a}higkeit. Dieses Buch beschreibt die wissenschaftlichen und psychophysiologischen Hintergr{\"u}nde von Biofeedback und der spezifischen Variante des Neurofeedback, welches auf der Messung der Gehirnaktivit{\"a}t beruht. Neben den angenommenen Wirkmechanismen und vielf{\"a}ltigen Varianten des Biofeedbacks auf Basis unterschiedlicher Biosignale und K{\"o}rpersysteme, z. B. Herz-Kreislauf-System, Muskelsystem, autonomes und zentrales Nervensystem, wird die zugrunde liegende Messtechnik erkl{\"a}rt. Zus{\"a}tzlich werden der typische Aufbau von Biofeedback-Sitzungen, die zugeh{\"o}rige Diagnostik sowie Standardprotokolle dargestellt. Das Vorgehen wird anhand von Fallbeispielen verschiedener St{\"o}rungsbilder veranschaulicht. Erl{\"a}uterungen zu typischen Anwendungsproblemen sollen ebenso zum Einsatz dieser vielseitigen Methode in der therapeutischen Praxis motivieren, wie der ausf{\"u}hrliche {\"U}berblick {\"u}ber die aktuelle Evidenz f{\"u}r Biofeedback. Das Buch ist damit eine Bereicherung f{\"u}r therapeutisch arbeitende Personen, die dieses auf objektiven Messungen basierende Verfahren einsetzen wollen, um ihr Behandlungsspektrum zu erweitern.},

  abstract  = {Habits are highly automated behaviors that have received renewed attention in addiction research. The Self-Report Habit Index (SRHI) is a widely used measure of habits. Two cross-sectional online studies aimed at validating a German version of the SRHI to assess two everyday health-risk behaviors: caffeine consumption and smartphone/tablet use. In both studies (N = 1310), the SRHI scales (one adapted for caffeine consumption, one for smartphone/tablet use), as well as corresponding addiction scales and health outcomes (study 1), or established validity measures (study 2), were assessed. Both SRHI scales showed satisfying item characteristics, high internal consistencies (αs > .90), adequate construct validity, and a three-factorial solution with a satisfying model fit (CFI/TLIs > .95, SRMRs ≤ 0.05). Highest correlations emerged between SRHI and addiction scales. The studies show that the German SRHI can be used to validly assess health-risk behaviors. The observed strong correlations of the SRHI scales with addiction scales suggest that (self-reported) habit is indeed an important aspect to consider in addiction research.},
