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.

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.
Body shaming (BS) is a popular term for a type of negative social interaction, which frequently occurs in social media. However, there is a lack of a clear scientific definition of BS and data on its relation to other concepts in social aggression research. The present study therefore aimed at providing a definition and classification of BS. In an exploratory online-study, 25 participants (60%) provided personal definitions of BS and rated the fit of a suggested definition. In addition, they reported similarities with and differences to related concepts (appearance teasing, cyberbullying, trolling). We conducted qualitative analyses of the verbal definitions guided by the Grounded Theory approach and quantified the fit to existing concepts in the field of social aggression. The results show that BS is perceived as an unrepeated act in which a person expresses unsolicited, mostly negative opinions/comments about a target’s body, without necessarily intending to harm him/her. Still, the target perceives the comments as negative. BS can range from well-meant advice to malevolent insults and it can occur online and offline. Participants saw similarities between BS and appearance teasing. BS can be a tool for trolling and can evolve to cyberbullying with repetition over time. Altogether, BS is a form of social aggression that has a negative impact on individuals. The definition and classification help to investigate BS and its effects on body image and mental health in future research.
Visually induced motion sickness (VIMS) is a common side-effect of exposure to virtual reality (VR). Its unpleasant symptoms may limit the acceptance of VR technologies for training or clinical purposes. Mechanical stimulation of the mastoid and diverting attention to pleasant stimuli-like odors or music have been found to ameliorate VIMS. Chewing gum combines both in an easy-to-administer fashion and should thus be an effective countermeasure against VIMS. Our study investigated whether gustatory-motor stimulation by chewing gum leads to a reduction of VIMS symptoms. 77 subjects were assigned to three experimental groups (control, peppermint gum, and ginger gum) and completed a 15-min virtual helicopter flight, using a VR head-mounted display. Before and after VR exposure, we assessed VIMS with the Simulator Sickness Questionnaire (SSQ), and during the virtual flight once every minute with the Fast Motion Sickness Scale (FMS). Chewing gum (peppermint gum: M = 2.44, SD = 2.67; ginger gum: M = 2.57, SD = 3.30) reduced the peak FMS scores by 2.05 (SE = 0.76) points as compared with the control group (M = 4.56, SD = 3.52), p < 0.01, d = 0.65. Additionally, taste ratings correlated slightly negatively with both the SSQ and the peak FMS scores, suggesting that pleasant taste of the chewing gum is associated with less VIMS. Thus, chewing gum may be useful as an affordable, accepted, and easy-to-access way to mitigate VIMS in numerous applications like education or training. Possible mechanisms behind the effect are discussed.
