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.
Abstract The development and application of digital interventions in health-related topics are gaining momentum in health service research. Digital interventions are often complex and need to be evaluated and implemented in complex settings. Due to their characteristics, this poses methodological challenges for health services research that have to be identified and addressed. Hence, the Working Group on Digital Health of the German Network for Health Services Research (DNVF) has prepared a discussion paper. This paper discusses methodological, practical and theoretical challenges associated with the development and evaluation of digital interventions from the perspective of health services research. Possible solutions are suggested and future research needs to address these methodological challenges are identified.
Abstract The methodological challenges of evaluating digital interventions (DI) for health services research are omnipresent. The Digital Health Working Group of the German Network for Health Services Research (DNVF) presented and discussed these challenges in a two-part discussion paper. The first part addressed challenges in definition, development and evaluation of DI. In this paper, which represents the second part, the definition of outcomes, reporting of results, synthesis of evidence, and implementation are addressed as methodological challenges of DI. Potential solutions are presented and the need to address these challenges in future research are discussed.
Pflege trifft Design

Trichotillomanie (TTM) ist durch repetitives Haareausreißen charakterisiert, was zu signifikantem Haarverlust, einem hohen Leidensdruck und Beeinträchtigungen in wesentlichen Lebensbereichen führt. Schätzungsweise ein bis zwei Prozent der Allgemeinbevölkerung leiden unter TTM. Gemeinsam mit anderen pathologischen körperbezogenen repetitiven Verhaltensweisen ist TTM in DSM-5 und ICD-11 dem Zwangsspektrum zugeordnet. In der Ätiologie stehen lerntheoretische Modelle im Vordergrund. Zur Behandlung wird die Kognitive Verhaltenstherapie empfohlen, wobei insbesondere Nachweise zur Effektivität des Habit-Reversal-Trainings vorliegen. Derzeit liegt keine evidenzbasierte Empfehlung für eine spezifische pharmakologische Behandlung vor. TTM ist bis heute ein wenig erforschtes und in der Praxis unzureichend bekanntes Störungsbild. Der vorliegende Beitrag liefert einen Überblick über den aktuellen Forschungsstand und allgemeine Handlungsempfehlungen für die Praxis.
Warum soll ich das Lernen? Lerngründe und Lernwiderstände in der theoretischen Pflegeausbildung
(2022)
Lernwiderstände sind Folge von unangemessener Lernanforderungen, die Lehrende an Schüler_innen richten. Vor allem Leistungsüberprüfungen und Leistungsdruck können Widerstände beim Lernen hervorrufen. Das kann zu negativen Emotionen wie Frustration und Hilflosigkeit beim Lernen führen. Außerdem erleben die Auszubildenden das Lernen als Zwang. Um diesen Problemen beizukommen ist es wichtig, sich die Relevanz von Lernbegründungen bewusst zu machen, damit Lernen als etwas positives wahrgenommen wird.
