Individual changes in stress, depression, anxiety, pathological worry, posttraumatic stress, and health anxiety from before to during the COVID-19 pandemic in adults from Southeastern Germany.

BACKGROUND: Many studies have previously compared the prevalence or sample means of distress and mental health problems from before to during the COVID-19 pandemic, while results on changes at the individual-level, and regarding multiple outcome measures are demanded. METHODS: This online study investigated individual changes in stress and mental health from before the COVID-19 pandemic to the first lockdown in adults from Southeastern Germany. This region was selected as it was where SARS-CoV-2 was first documented in Germany, and also due to the implementation of strict stay-at-home orders and social contact prohibitions. From April 10-27, 2020, we collected state measures and their clinical relevance for the subareas of perceived stress: worries, tension, joy, and demands. We also collected information regarding the following mental health problems: depression, anxiety, pathological worry, posttraumatic stress disorder (PTSD), and health anxiety; as well as retrospective measures of how participants felt they have changed in comparison to before the pandemic, ranging from worse to better. RESULTS: The analytical sample comprised 396 adult participants. On average, participants experienced increases in worries, tension, and lack of joy, and increases in mental health problems, but a decrease in demands. Perceived increases in symptoms of depression (26.0%) and PTSD (25.5%) were significantly more frequent than in symptoms of anxiety (particularly acute fear and panic) (5.6%), pathological worry (9.8%), and health anxiety (7.3%) (ps<.001). One per 10 participants (10.4%) reported an increase in depressive symptoms, and nearly two per 10 (18.4%) an increase in PTSD symptoms and additionally showed a clinically relevant symptom strain during lockdown. Interestingly, mainly non-specific PTSD symptoms associated with a general stress reaction were experienced to be increased. CONCLUSION: The findings suggest a dissociation of perceived changes in subareas of stress and mental health with a particular experience of increases in depressive and general stress symptoms and a decrease in external demands. This points to a need for a more differentiated view on the impact of the COVID-19 pandemic on stress and mental health, and for targeted interventions for mental health problems arising frequently during the pandemic.

Face masks reduce interpersonal distance in virtual reality.

During the COVID-19 pandemic several behavioral measures have been implemented to reduce viral transmission. While these measures reduce the risk of infections, they may also increase risk behavior. Here, we experimentally investigate the influence of face masks on physical distancing. Eighty-four participants with or without face masks passed virtual agents in a supermarket environment to reach a target while interpersonal distance was recorded. Agents differed in wearing face masks and age (young, elderly). In addition, situational constraints varied in whether keeping a distance of 1.5 m required an effortful detour or not. Wearing face masks (both self and other) reduced physical distancing. This reduction was most prominent when keeping the recommended distance was effortful, suggesting an influence of situational constraints. Similarly, increased distances to elderly were only observed when keeping a recommended distance was effortless. These findings highlight contextual constraints in compensation behavior and have important implications for safety policies.

Widespread Recommendations Can Change Our Habits of Hand-Washing and Physical Distance During the COVID-19 Pandemic.

Background: Habits and behaviors in everyday life currently need to be modified as quickly as possible due to the COVID-19 pandemic. Two of the most effective tools to prevent infection seem to be regular and thorough hand-washing and physical distancing during interpersonal interactions. Method: Two hundred and eighty-four participants completed a short survey to investigate how previous habits regarding hand-washing and physical distancing have changed in the general population as a function of the current pandemic and the thereby increased information and constant recommendations regarding these behaviors. Results: Participants aged 51 and older reported a greater change in everyday hand-washing behavior than younger participants. In addition, participants aged 31 and older selected significantly greater distances to have a conversation than younger participants. However, that was not the case if participants had to actively stop their conversational partner from approaching. Conclusion: Participants aged 51 years and older seem to be well aware of their at-risk status during the current pandemic and might therefore be willing to change their behavior more strongly than younger survey participants. Nevertheless, they seem to struggle with enforcing the current rules towards others. The group aged between 31 and 50 years, however, reports a comparable level of fear, but no corresponding change in hand-washing behavior. Future surveys should try to provide more insight into why this might be the case.
