Adhärenz digitaler Interventionen im Gesundheitswesen: Definitionen, Methoden und offene Fragen
(2021)
AbstractMany digital interventions rely on the participation of their users to have a positive impact. In various areas it can be observed that the use of digital interventions is often reduced or fully discontinued by the users after a short period of time. This is seen as one of the main factors that can limit the effectiveness of digital interventions. In this context, the concept of adherence to digital interventions is becoming increasingly important. Adherence to digital interventions is roughly defined as “the degree to which the user followed the program as it was designed,” which can also be paraphrased as “intended use” or “use as it is designed.” However, both the theoretical–conceptual and practical discussions regarding adherence to digital interventions still receive too little attention.The aim of this narrative review article is to shed more light on the concept of adherence to digital interventions and to distinguish it from related concepts. It also discusses the methods and metrics that can be used to operationalize adherence and the predictors that positively influence adherence. Finally, needs for action to better address adherence are considered critically.
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.
Background
During shortages of filtering face pieces (FFP) in a pandemic, it is necessary to implement a method for safe reuse or extended use. Our aim was to develop a simple, inexpensive and ecological method for decontamination of disposable FFPs that preserves filtration efficiency and material integrity.
Specific alterations in electroencephalography (EEG)-based brain activity have recently been linked to binge-eating disorder (BED), generating interest in treatment options targeting these neuronal processes. 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 à 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.
