Investigating stress and health behaviour relationships in daily life: Towards a framework for advancing future research
Stress is of major relevance for health and well-being. Health behaviour is one pathway by which stress affects health. Less research has jointly investigated stress and health behaviour but lately it has gained traction owing to the increased availability of methods for studying daily life that allow stress and health behaviour to be studied when and where it occurs. However, findings are highly heterogeneous, with studies finding positive, nega…
Combining social media literacy with self-compassion: Testing the SoSelf mHealth training
During teenage years and early adulthood, many women experience high stress levels regarding their appearance. Especially appearance-related comparisons on social media fuel body dissatisfaction. To remedy this, both social media literacy and self-compassion interventions have each been shown as separately effective but are rarely implemented together. The SoSelf training does so in the context of an ecological momentary assessment (EMA) study. T…
Mechanisms of emotional eating: Food approach bias covaries with affect on days with high food craving
Emotional eating (EE) - eating in response to emotions - has clinical relevance, yet its underlying mechanisms (how?) remain poorly understood. Questions also concern interindividual differences (who?), and the types of foods involved (what?). We hypothesized that negative affect would be linked to increased, and positive affect to decreased food approach bias (how?). These effects were expected to be moderated by trait EE (who?) and by the goal-…
Emotional food craving: Highest during positive emotions, and calorie-specific during negative emotions
OBJECTIVE: Theories on emotional eating are central to understanding the etiology, maintenance, and treatment of eating and weight disorders. However, it remains unclear whether emotional eating is a universal phenomenon or specific to a subgroup with distinct eating styles. Few studies have examined positive and negative emotions within the same design. This study aimed to investigate the effects of induced positive and negative emotions on food…
Reaction-time task reliability is more accurately computed with permutation-based split-half correlations than with Cronbach’s alpha
While it has become standard practice to report the reliability of self-report scales, it remains uncommon to do the same for experimental paradigms. To facilitate this practice, we review old and new ways to compute reliability in reaction-time tasks, and we compare their accuracy using a simulation study. Highly inaccurate and negatively biased reliability estimates are obtained through the common practice of averaging sets of trials and submit…
Bidirectional associations between affect and food craving within and between individuals: A mega-analysis
The empirical robustness of emotional eating and stress eating - the tendency to eat in response to affective experience - is under ongoing debate. Is this a general phenomenon or is this seen only in certain groups? And, if so, can such interindividual differences be reliably assessed with self-report questionnaires? Here, we approach this question not through measuring overt eating - a behavior that is subject to several contextual conditions -…
Retracted: The only constant is change: Stable vs. variable aspects of food approach bias relate differently to food craving and intake
The tendency to approach food faster than to avoid it (i.e., approach bias) is thought to facilitate food intake, particularly foods that conflict with one's dietary goals. However, this relationship has been difficult to demonstrate, which ties into an ongoing debate about whether such cognitive-behavioral biases represent stable traits or fluctuating states. We thus investigated the temporal fluctuations of food approach bias (1), its within-pa…
Shaping food choices with actions and inactions with and without reward and punishment
Taming “hanger” and falling prey to boredom-emotional and stress-eating in 801 healthy individuals using ecological momentary assessment
Emotional eating and Stress Eating concepts hold that affective experiences can instill the desire for palatable foods. The empirical evidence for such couplings between affective and appetitive systems, however, is mixed and it remains unclear which one precedes the other or whether interindividual differences in such relationships exist. To study the temporal relations between a range of negative and positive emotions and stress on the one hand…
The dual-feature approach-avoidance task: Validity, Training Efficacy, and the Role of Contingency Awareness in Changing Food Preference
rate of approaching fruit versus chocolate correlated with many outcome measures, suggesting contingency awareness plays a major role in AAT training effectiveness, challenging implicit accounts. While the dual-feature paradigm shows potential, its high error rates, RTs, and difficulty mandate improvement
Stable cognitive performance while adapting to intermittent fasting: A randomised controlled trial
Intermittent fasting (IF) is a popular health regimen for weight loss and overall health. Yet, potential negative side effects on cognition and mood could hinder its adoption. Such side effects, however, have so far only been studied in short term exposures to IF. We tested whether fasting impairs cognitive performance and mood when adapting to 16-hour, breakfast-skipping IF over 10 days in a randomised, waitlist-controlled trial ( N = 122). Cogn…

Imagine chocolate: The craving experience questionnaire in the food domain
Measurement of food craving has gained relevance in the current obesity epidemic. The Craving Experience Questionnaire (CEQ) considers not only craving intensity but also cognitive intrusiveness and imagery vividness as separate craving factors and could thus refine food craving assessment. It is available in two versions with ten items each. The CEQ-F assesses craving frequency across specific time periods and the CEQ-S time-point specific cravi…
Devaluation of NoGo stimuli is both robust and fragile
Consistently not responding to stimuli during go/no-go training leads to lower evaluations of these NoGo stimuli. How this NoGo-devaluation-effect can be explained has remained unclear. Here, we ran three experiments to test the hypothesis that people form stimulus-stop-associations during the training, which predict the strength of the devaluation-effect. In Experiment 1, we tried to simultaneously measure the stimulus-stop-associations and NoGo…
Touchscreen-based measurement of food approach-avoidance bias: Seeking a reliable and valid paradigm
I change my mind to get better: Process tracing-based microanalysis of food choice processes reveals differences between anorexia nervosa and bulimia nervosa during inpatient treatment
Food choice and its underlying processes is understudied in bulimia nervosa (BN) and anorexia nervosa (AN). Thus, we examined cognitive processes during food choice through mouse tracing in AN (n = 36) and BN (n = 27) undergoing inpatient treatment. Both patient groups and matched healthy controls (HC, n = 59) made 153 binary food choices before rating all foods on their liking and calorie density. Choice outcomes and corresponding mouse movement…
(Mouse cursor)-Tracking food decisions in binge eating disorder reveals preference for high-energy foods and a role of BMI
Binge Eating Disorder (BED) has been associated with deficits in cognitive control and decision-making. Yet, no study has yet investigated the characteristics of food choice and the involved choice conflict in this disorder. In the present study individuals with BED (N = 22) and without BED (N = 61), with a body mass index (BMI) between 21 and 44 completed 153 binary food decisions among foods varying in palatability and energy density. To assess…
Increased Screen Use on Days With Increased Perceived Covid-19-Related Confinements—A Day Level Ecological Momentary Assessment Study
Introduction: Coronavirus 2019 (COVID-19) quickly evolved into a global pandemic in early 2020, and most countries enforced social confinements to reduce transmission. This seems to dovetail with increasing, potentially problematic, screen use habits, such as gaming and “binge-watching.” Yet, the subjective experience of the common confinements may vary not only between individuals depending on age, sex, and living conditions (i.e., living alone)…
Does stress eat away at you or make you eat? EMA measures of stress predict day to day food craving and perceived food intake as a function of trait stress-eating
Eating behaviour can be driven by non-homeostatic factors like stress. Both increased and decreased food intake in response to stress has been documented, but it has remained difficult to identify a trait that predicts who shows either pattern. Thus, we collected naturalistic data from Ecological Momentary Assessment in combination with the trait-level Salzburg Stress Eating Scale (SSES). In study 1, 97 individuals completed the SSES and 6 daily …
Working towards a reliable and valid touchscreen-based food approach avoidance task: A mini-review
Characterising binge eating over the course of a feasibility trial among individuals with binge eating disorder and bulimia nervosa
Binge eating disorder and bulimia nervosa are eating disorders that are characterized by recurrent binge eating episodes. The highly contextualized nature of binge eating makes naturalistic research a particularly suitable means of understanding the context within which binge eating occurs. The present study aimed to characterise binge eating days with regards to the frequency and probability of negative affect, food craving, meal skipping, and d…
Touchscreen-based assessment of food approach biases: Investigating reliability and item-specific preferences
Strong cravings for unhealthy foods and implicit tendencies to approach them threaten the physical and mental health of vulnerable populations. Yet, implicit measures of food approach tendencies have methodological limitations, as existing approach-avoidance tasks (AAT) are often unreliable and require specialized hardware. We propose a novel method to measure approach biases: on a touchscreen, participants slide their hand either toward a food i…

Comparison of different response devices to assess behavioral tendencies towards chocolate in the approach-avoidance task
Food approach bias is moderated by the desire to eat specific foods
In a post-scarcity world, energy intake and excesses therein are mediated by psychological mechanisms, such as implicit inclinations to approach certain foods. We investigated how food deprivation, calorie content and individual food preferences affect this approach bias. Sixty women performed a touchscreen-based approach-avoidance task featuring a wide range of food items, once while satiated and once while food-deprived for 15 h. We found an ov…

Suppressing images of desire: Neural correlates of chocolate-related thoughts in high and low trait chocolate cravers
Autonomic and Respiratory Characteristics of Posttraumatic Stress Disorder and Panic Disorder
Objective: Posttraumatic stress disorder (PTSD) and panic disorder (PD) are two anxiety disorders with prominent psychophysiological symptoms. The PTSD criterion of persistent hyperarousal suggests autonomic dysregulation, and the disorder has been associated with elevated heart rate. In contrast, PD has been associated with respiratory abnormalities such as low end-tidal Pco2. An integrated analysis of automatic and respiratory function in a dir…
Social Comparison and Its Relation to Body Dissatisfaction in Bulimia Nervosa: Evidence From Eye Movements
OBJECTIVE: To determine the role of social comparison for body dissatisfaction in bulimia nervosa (BN). Previous research suggested that exposure to media content idealizing thin body shape decreases body satisfaction, particularly in women with eating disorder symptoms. This might be due to the negative outcome of social comparisons with media models, and women with eating disorders might be particularly susceptible because they engage in upward…
Respiratory Pathophysiology of Panic Disorder: An Ambulatory Monitoring Study
Objective: To assess the external validity of laboratory baselines in panic disorder (PD), frequently associated with respiratory pattern abnormalities like increased respiratory variability and sighing, implying a stable pathophysiologic trait characteristic. Methods: Physical activity and a variety of breath-by-breath volumetric, timing, and variability measures of respiration were recorded in the daily life of 26 patients with PD and 26 health…

Electrocortical Processing of Food and Emotional Pictures in Anorexia Nervosa and Bulimia Nervosa
Objective: To compare the electrocortical processing of food pictures in participants with anorexia nervosa (n = 21), bulimia nervosa (n = 22), and healthy controls (HCs) (n = 32) by measuring the early posterior negativity, an event-related potential that reflects stimulus salience and selective attention. Methods: We exposed these three groups to a rapid stream of high- and low-calorie food pictures, as well as standard emotional and neutral pi…

Emotion regulation choice: A conceptual framework and supporting evidence.
Choice behavior is considered the fundamental means by which individuals exert control over their environments. One important choice domain that remains virtually unexplored is that of emotion regulation. This is surprising given that healthy adaptation requires flexibly choosing between regulation strategies in a manner that is responsive to differing situational demands. In the present article, we provide a broad conceptual framework that syste…
Food-pics: An image database for experimental research on eating and appetite
Our current environment is characterized by the omnipresence of food cues. The sight and smell of real foods, but also graphically depictions of appetizing foods, can guide our eating behavior, for example, by eliciting food craving and influencing food choice. The relevance of visual food cues on human information processing has been demonstrated by a growing body of studies employing food images across the disciplines of psychology, medicine, a…
