The psychological science accelerator’s COVID-19 rapid-response dataset
In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data

Reward and Anxiety: From Rodent Post-Traumatic Stress to Human Psychosocial Stress
Posttraumatic stress disorder (PTSD) is a chronic disabling condition that results from exposure to traumatic stress. However, although trauma is fairly common, PTSD will only occur in a small proportion of people. This suggests that resilience is a common response to trauma. The neurobiology underlying this adaptive response is thought to involve reward related areas as well as reward functions. This dissertation proposes that reward and reward-related areas have a role in anxiety disorders such as PTSD. This hypothesis was explored using an animal model of PTSD as well as a human mode of psychosical stress. The hypothesis that the ventral tegmental area (VTA), crucial for reward processing, is part of the neural circuitry involved in the symptomatology of PTSD was explored. To assess the role of VTA in PTSD, cells in this area were reversibly inactivated during a single exposure to inescapable foot-shock in a rodent model. Animals that underwent inactivation of VTA neurons decreased avoidance and lowered long-term anxiety-like behaviors in comparison with control groups. To assess short- and long-term electrophysiological effects of trauma on VTA cells, in vivo extracellular recordings were conducted. Results showed that the firing frequency of VTA cells changed both in the short- and long-term, following shock procedures. A human model of psychosical stress was used to test the hypothesis that the ability to respond appropriately to positive stimuli is important for the preservation of positive emotions following stressful events. The results show a positive correlation between trait resilience and trait reward sensitivity. To investigate the link between resilience and reward sensitivity further, the empirical portion of this study used a Monetary Incentive Delay Task (MID) to measure reward sensitivity before and after exposure to a psychosocial stressor. Moreover, behavioral reward sensitivity (as measured by MID and self-report satisfaction after the reward task) also correlated positively with trait and behaviorally measured resilience. The results shown in this dissertation suggest that the neural circuits involved in reward processing and reward function may be involved in resilient responses to stress

Attitudes About COVID-19 and Health (ATTACH): Online survey and mixed methods Study
Background:Behavioral mitigation strategies to slow the spread of COVID-19 have resulted in sweeping lifestyle changes, with short- and long-term psychological, well-being, and quality of life implications. The Attitudes About COVID-19 and Health (ATTACH) study focuses on understanding attitudes and beliefs while considering the impact on mental and physical health and the influence of broader demographic and geographic factors on attitudes, beliefs, and mental health burden.Objective:In this assessment of our first wave of data collection, we provide baseline cohort description of the ATTACH study participants in the United Kingdom, the United States, and Mexico. Additionally, we assess responses to daily poll questions related to COVID-19 and conduct a cross-sectional analysis of baseline assessments collected in the UK between June 26 and October 31, 2020.Methods:The ATTACH study uses smartphone app technology and online survey data collection. Participants completed poll questions related to COVID-19 2 times daily and a monthly survey assessing mental health, social isolation, physical health, and quality of life. Poll question responses were graphed using 95% Clopper–Pearson (exact) tests with 95% CIs. Pearson correlations, hierarchical linear regression analyses, and generalized linear models assessed relationships, predictors of self-reported outcomes, and group differences, respectively.Results:By October 31, 2020, 1405, 80, and 90 participants had consented to participate in the UK, United States, and Mexico, respectively. Descriptive data for the UK daily poll questions indicated that participants generally followed social distancing measures, but worry and negative impacts on families increased as the pandemic progressed. Although participants generally reported feeling that the reasons for current measures had been made clear, there was low trust that the government was doing everything in its power to meet public needs. In the UK, 1282 participants also completed a monthly survey (94.99% [1326/1396] White, 72.22% [1014/1404] female, and 20.12% [277/1377] key or essential workers); 18.88% (242/1282) of UK participants reported a preexisting mental health disorder, 31.36% (402/1282) reported a preexisting chronic medical illness, and 35.11% (493/1404) were aged over 65; 57.72% (740/1282) of participants reported being more sedentary since the pandemic began, and 41.89% (537/1282) reported reduced access to medical care. Those with poorer mental health outcomes lived in more deprived neighborhoods, in larger households (Ps<.05), had more preexisting mental health disorders and medical conditions, and were younger than 65 years (all Ps<.001).Conclusions:Communities who have been exposed to additional harm during the COVID-19 pandemic were experiencing worse mental outcomes. Factors including having a medical condition, or living in a deprived neighborhood or larger household were associated with heightened risk. Future longitudinal studies should investigate the link between COVID-19 exposure, mental health, and sociodemographic and residential characteristics
