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.}, language = {en} } @article{GallinatMartinSchmidt2020, author = {Gallinat, Christina and Martin, Alexandra and Schmidt, Jennifer}, title = {Dermatillomanie: Symptomatik, {\"A}tiologie und Therapie des pathologischen Bearbeitens der Haut}, series = {Psychotherapeut}, volume = {65}, journal = {Psychotherapeut}, doi = {10.1007/s00278-020-00437-7}, pages = {313 -- 328}, year = {2020}, language = {de} } @article{SchmidtMartin2017, author = {Schmidt, Jennifer and Martin, Alexandra}, title = {Du magst mich nicht, weil ich h{\"a}sslich bin!

This randomized-controlled pilot study examined the effectiveness and feasibility of two EEG neurofeedback paradigms in the reduction of binge eating, eating disorder and general psychopathology, executive functioning, and EEG activity. Adults with BED and overweight (N = 39) were randomly assigned to either a food-specific EEG neurofeedback paradigm, aiming at reducing fronto-central beta activity and enhancing theta activity after viewing highly palatable food pictures, or a general EEG neurofeedback paradigm training the regulation of slow cortical potentials. In both conditions, the study design included a waiting period of 6 weeks, followed by 6 weeks EEG neurofeedback (10 sessions {\`a} 30 min) and a 3-month follow-up period. Both EEG neurofeedback paradigms significantly reduced objective binge-eating episodes, global eating disorder psychopathology, and food craving. Approximately one third of participants achieved abstinence from objective binge-eating episodes after treatment without any differences between treatments. These results were stable at 3-month follow-up. Among six measured executive functions, only decision making improved at posttreatment in both paradigms, and cognitive flexibility was significantly improved after food-specific neurofeedback only. Both EEG neurofeedback paradigms were equally successful in reducing relative beta and enhancing relative theta power over fronto-central regions. The results highlight EEG neurofeedback as a promising treatment option for individuals with BED. Future studies in larger samples are needed to determine efficacy and treatment mechanisms.}, language = {en} } @article{OpwisSchmidtMartinetal.2017, author = {Opwis, Mareile and Schmidt, Jennifer and Martin, Alexandra and Salewski, Christel}, title = {Gender differences in eating behavior and eating pathology: The mediating role of rumination}, series = {Appetite}, volume = {110}, journal = {Appetite}, issn = {0195-6663}, pages = {103 -- 107}, year = {2017}, language = {en} } @article{SchmidtMartin2017, author = {Schmidt, Jennifer and Martin, Alexandra}, title = {Herzratenvariabilit{\"a}ts-Biofeedback in der klinischen Praxis: Grundlagen, Anwendung und Evidenz auf Basis eines systematischen Reviews}, series = {Psychotherapeut}, volume = {62}, journal = {Psychotherapeut}, number = {6}, issn = {0935-6185}, pages = {498 -- 506}, year = {2017}, language = {de} } @article{SchmidtMartin2016, author = {Schmidt, Jennifer and Martin, Alexandra}, title = {Neurofeedback against binge eating - A randomized controlled trial in a female subclinical threshold sample}, series = {European Eating Disorders Review}, volume = {24}, journal = {European Eating Disorders Review}, number = {5}, issn = {1072-4133}, pages = {406 -- 416}, year = {2016}, language = {en} } @article{SchmidtMartin2015, author = {Schmidt, Jennifer and Martin, Alexandra}, title = {Neurofeedback reduces overeating episodes in female restrained eaters - A randomized controlled pilot-study}, series = {Applied Psychophysiology and Biofeedback}, volume = {40}, journal = {Applied Psychophysiology and Biofeedback}, number = {4}, issn = {1090-0586}, pages = {283 -- 295}, year = {2015}, language = {en} } @article{SchmidtMartin2021, author = {Schmidt, Jennifer and Martin, Alexandra}, title = {Smartphone-Apps zur Verbesserung der K{\"o}rperzufriedenheit?
