Depressive and Anxious Symptoms, Experimentally Manipulated Acute Social-Evaluative Threat, and Cortisol Reactivity.

OBJECTIVE: Exposure to social-evaluative threat (SET) can elicit greater physiological responses, including cortisol, compared to non-SET stressors. An individual's level of depressive and anxious symptoms predicts variability in cortisol responses to stressors, and other research suggests these individual differences may predict vulnerability to social evaluation. The current study integrates both lines of research, testing if there are different relationships between depressive and/or anxious symptoms and cortisol reactivity in the presence or absence of SET. METHODS: Healthy undergraduate students (N = 158, 65% female) were randomly assigned to deliver a speech in the presence (SET) or absence (non-SET) of two evaluators. Salivary cortisol was collected throughout, and self-reported depressive and anxious symptoms were assessed. We hypothesized that in the SET condition, higher levels of depressive and/or anxious symptoms would predict dysregulated cortisol responses compared to lower levels of symptoms and/or assignment to the non-SET group. RESULTS: In spite of inconclusive p-values (which might be attributed to low statistical power), individuals with high depressive or high anxious symptoms appeared to have exaggerated cortisol responses in the SET condition, as indicated by more concave trajectories. CONCLUSIONS: This study suggests that both depression and anxiety could be associated with increased cortisol reactivity to SET.

Self-administered mindfulness interventions reduce stress in a large, randomized controlled multi-site study.

Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ ; retrospective registration at ClinicalTrials.gov NCT06308744 ) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single, standalone mindfulness exercises effectively reduced stress, using Bayesian mixed-effects models. All exercises proved to be more efficacious than the active control. We observed a mean difference of 0.27 (d = -0.56; 95% confidence interval, -0.43 to -0.69) between the control condition (M = 1.95, s.d. = 0.50) and the condition with the largest stress reduction (body scan: M = 1.68, s.d. = 0.46). Our findings suggest that mindfulness may be beneficial for reducing self-reported short-term stress for English speakers from higher-income countries.

"I enjoy the good foods, all of which are not good for me." The categorization and moralization of food.

Intuitive eating emphasizes eating in response to physiological cues of hunger and satiety and is associated with multiple positive health outcomes. Unconditional permission to eat (UPE), a domain of intuitive eating, encourages removing food classifications and permission to eat all foods. However, the categorization of food is described as a method to simplify decision making and moralization of foods can help prioritize food items in consumption. Thus, we were interested in understanding how foods are labeled and applied, the moralization of foods, and how individuals with low UPE labeled and moralize foods. Using Prolific Academic, we recruited 49 adults 18 years and older living in the United States to complete an online survey and interview. The survey assessed intuitive eating (IES-2) and the interview explored what and how participants eat and their thoughts and feelings about their body. Participants frequently used multiple labels when talking about foods. Healthy and unhealthy were common and offered a rationale for consumption, emotions were used to label foods, and taste and cost were important to food choice. Participants frequently moralized foods, although three participants explicitly stated they choose not to moralize foods. Individuals reporting low UPE described the importance of restriction and were following strict dietary recommendations. While labeling foods has been proposed to simplify decision-making, the use of labels is highly nuanced and thus understanding the connections between how foods are labeled and behaviors may be highly complex. We suggest future research explore how the categorization and moralization of food are associated with health behaviors and outcomes, how differing definitions of "healthy/unhealthy" foods are associated with behaviors, and the impacts of food insecurity and chronic disease management on food categorization and moralization.
