Item Cognitive reappraisal of low-calorie food predicts real-world craving and consumption of high- and low-calorie foods in daily life(Elsevier, 2018) Reader, Shane W.; Lopez, Richard B.; Denny, Bryan T.In an increasingly obesogenic environment, an individual's regulatory capacity to pursue nutrient-rich, low-calorie foods over palatable, energy-dense items is essential to maintaining a healthy weight and preventing the detrimental health risks of obesity. Cognitive reappraisal, the process by which one changes the meaning of a stimulus by altering its emotional impact (or in this case, its appetitive value) demonstrates promise as a regulatory strategy to decrease obesogenic food consumption, but little research has directly addressed the relationship between cognitive reappraisal of food cravings and real-world eating behaviors. Additionally, research examining self-regulation of eating has typically focused exclusively on diminishing cravings and consumption of unhealthy, high-calorie foods, rather than examining, in tandem, ways to strengthen (or, up-regulate) cravings for healthier, low-calorie alternatives. In the present study, fifty-seven college aged participants first completed a cognitive reappraisal task in the laboratory in which they practiced regulating their craving responses to high- and low-calorie food items by focusing on the long-term health consequences of repeatedly consuming the pictured foods. Next, for a week following the laboratory session, participants reported daily eating behaviors via ecological momentary assessment. Participants who reported greater up-regulatory success during the reappraisal task also reported increased craving strength for low-calorie foods as well as decreased consumption of high-calorie foods in their daily lives. Greater overall regulation success also predicted more frequent consumption of craved low-calorie foods. These findings substantiate the association between cognitive reappraisal ability and real-world appetitive behaviors, and suggest that future interventions may benefit from specifically targeting individuals' evaluations of low-calorie foods.Item Emotion regulation during encoding reduces negative and enhances neutral mnemonic discrimination in individuals with depressive symptoms(Elsevier, 2023) Hayes, Brandon K.; Harikumar, Amritha; Ferguson, Lorena A.; Dicker, Eva E.; Denny, Bryan T.; Leal, Stephanie L.Individuals with depression exhibit dysfunctional emotion regulation, general episodic memory deficits, and a negativity bias, where negative experiences are better remembered. Recent work suggests that the negativity bias in depression may be driven by enhanced mnemonic discrimination, a memory measure that relies on hippocampal pattern separation – a computation that processes experiences with overlapping features as unique. Previously, we found that individuals with depressive symptoms show enhanced negative and impaired neutral mnemonic discrimination. The current study aimed to investigate emotion regulation as an approach toward modifying memory encoding of negative and neutral events in individuals with depressive symptoms. Here we show that applying psychological distancing (a cognitive reappraisal strategy characterized by taking a third-person perspective toward negative events) during encoding was associated with reduced negative and enhanced neutral mnemonic discrimination during retrieval in individuals with depressive symptoms. These results suggest that applying emotion regulation techniques during encoding may provide an effective approach toward altering dysfunctional memory in those with depressive symptoms. Given that pharmacological treatments often fail to treat depression, emotion regulation provides a powerful and practical approach toward modifying cognitive and emotional processes. Future neuroimaging studies will be important to determine how emotion regulation impacts the neural mechanisms underlying these findings.Item Lexical markers of cognitive reappraisal, bereavement, and proinflammatory cytokine production(American Psychological Association, 2023) Shahane, Anoushka D.; Brown, Ryan L.; Denny, Bryan T.; Fagundes, Christopher P.Objective: The loss of a spouse is considered one of the most significant life change-related stressors. Bereaved spouses have significantly increased risk of chronic inflammation, and ultimately greater morbidity and mortality. High levels of proinflammatory cytokines are related to negative health outcomes. In bereavement, the ability to successfully regulate emotion is a vital skill for healthy coping and may represent a key psychological mechanism accounting for varying degrees of resilience. Psychological distancing is a frequently adaptive emotion regulation strategy in which an individual appraises a negative situation by taking a step back and distancing oneself, and coolly evaluates what is happening. The objective of the present work was to investigate whether psychological distancing, implemented implicitly via natural language use (i.e., linguistic distancing [LD]), is related to inflammation and bereavement-related health indicators. Method: Participants (N = 144) underwent a blood draw for the inflammation assay, completed questionnaire measures evaluating grief symptoms and health, and completed an oral task describing their relationship with their deceased spouse, which was used for the lexical analyses. Results: We found that LD was significantly associated with a panel of a priori proinflammatory stimulated cytokines (TNF-α, IL-6, IFN-γ, IL-17A, and IL-2), bereavement-related health indices, and the relationship between grief symptoms and inflammation varied depending on the participants’ implementation of LD. Conclusions: LD may have a buffering effect for this vulnerable population. This work elucidates novel dependencies among language, emotion, and health. This work identifies resilience factors and probes the translational value of LD.Item Negative affect mediates the relationship between use of emotion regulation strategies and general health in college-aged students(Elsevier, 2019) Lopez, Richard B.; Denny, Bryan T.Patterns of dysregulated emotions can take a toll on both mental and physical health. Such patterns also put people at risk for affective disorders, including anxiety and depression. Early adulthood is a critical period during which affective disorders first develop, so there is a need to identify individual difference factors that predispose some young adults to develop anxiety and depression. Here, we recruited a sample of college-aged volunteers (N = 393) and assessed their use of multiple emotion regulation strategies, depressive and anxiety symptoms, and general health. We hypothesized that cognitive reappraisal would be associated with better health, via fewer reported depressive and anxiety symptoms, whereas expressive suppression would be associated with poorer health, via more depressive and anxiety symptoms. To test these hypotheses, we fit a mediation model with cognitive reappraisal and expressive suppression as predictors, anxiety and depressive symptoms as mediating variables, and a global health measure as the outcome. There were robust direct and indirect associations in support of our hypotheses. These results suggest that targeting emotion regulation abilities in early adulthood may be an effective strategy to reduce the risk of developing affective disorders and improve overall health.Item Perceived partner responsiveness alters the association between marital distress and well-being in dementia spousal caregivers(Elsevier, 2024) Lai, Vincent D.; Paoletti-Hatcher, Jensine; Wu-Chung, E. Lydia; Mahant, Itee; Argueta, Daniel L.; Brice, Kelly N.; Denny, Bryan T.; Green, Charles; Medina, Luis D.; Schulz, Paul E.; Stinson, Jennifer M.; Heijnen, Cobi J.; Fagundes, Christopher P.Caregivers for spouses with Alzheimer's disease and related dementias (ADRD) experience drastic changes in the marital relationship that may put them at risk for worsening well-being. Perceived partner responsiveness, or feeling cared for, understood, and appreciated by one's spouse, may help mitigate these effects. In this study, we investigated the associations between marital distress, perceived partner responsiveness, and psychological and physiological well-being indicators among ADRD spousal caregivers. Method A sample of 161 caregivers provided blood samples and completed self-report measures of marital distress, perceived partner responsiveness, and depressive symptoms. We tested hypotheses in our sample cross-sectionally based on two theoretical frameworks. Results Testing the marital discord model of depression, caregivers who reported greater marital distress also reported more depressive symptoms, and this association was stronger as participants reported lower perceived partner responsiveness. Caregivers who reported greater marital distress exhibited elevated proinflammatory cytokine production by in vitro lipopolysaccharide (LPS)-stimulated peripheral blood leukocytes at low levels of perceived partner responsiveness, but not mean or high levels. Testing the vulnerability-stress-adaptation model, caregivers who reported more depressive symptoms also reported greater marital distress. Further, caregivers who exhibited elevated LPS-stimulated proinflammatory cytokine production reported greater marital distress at mean and high levels of perceived partner responsiveness, but not low levels. These patterns of results held even when accounting for the dementia stage and reported hours of caregiving per day. Discussion This study's findings contribute to the body of research examining interpersonal factors that shape health and well-being among the caregiver population.Item Predicting emotional health indicators from linguistic evidence of psychological distancing(Wiley, 2019) Shahane, Anoushka D.; Denny, Bryan T.Psychological distancing, a form of cognitive reappraisal, involves construal of emotionally valenced stimuli in an objective manner, or with perceived spatial and temporal distance. Prior work suggests that in appropriate contexts, reappraisal broadly, and distancing specifically, is related to adaptive mental and physical health outcomes. Additionally, recent research suggests that shifting language to be more distant (i.e., linguistic distancing [LD]) can have adaptive emotion regulatory effects. The present study addressed whether LD is also associated with adaptive health indicators. Participants transcribed their thoughts while viewing negative or neutral stimuli in one of three ways: (a) by implementing objective language, (b) by implementing spatially and/or temporally far away language, or (c) by responding naturally. Across psychological distancing groups, LD was associated with lower negative affectivity (lower perceived stress and depression symptoms), better general well‐being (better emotional well‐being and energy and vitality), and better emotion regulation (ER; greater reappraisal frequency and fewer difficulties in implementing ER). Participants who used more LD in the objective group had lower negative affectivity, better general well‐being, and better ER, and those in the far group had better ER. The results reveal linguistic mechanisms underlying ER and its relationship to health indicators, suggesting future examination of LD interventions.Item What Instagram Means to Me: Links Between Social Anxiety, Instagram Contingent Self-worth, and Automated Textual Analysis of Linguistic Authenticity(Springer Nature, 2024) Brandao, Beatriz M.; Denny, Bryan T.While research has shown mixed effects of social media on mental health and well-being, little is known about the association between social media attitudes and objective measures of social interaction, such as linguistic authenticity. This study examined the relationship between self-reported social anxiety, linguistic authenticity, and Instagram contingent self-worth (ICSW). A total of 149 adults with active Instagram accounts completed online questionnaires and shared their Instagram comment data. Automated linguistic analysis of authenticity was performed on participants’ comment data using validated algorithms. Multiple linear regression showed that ICSW significantly moderated the relationship between social anxiety and linguistic authenticity, whereby higher levels of social anxiety marginally predicted lower linguistic authenticity at high levels of ICSW. As social media use continues to rise, this study emphasizes the need to explore the impact of social media interactions on emotional and social well-being.
