Biomedicines 2023; 11:2644. [PMID: 37893019 PMCID: PMC10603884 DOI: 10.3390/biomedicines11102644] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 08/30/2023] [Accepted: 09/19/2023] [Indexed: 10/29/2023] Open
Abstract
This study analyzed genetic risk assessments in patients undergoing bariatric surgery to serve as a predictive factor for weight loss parameters 1 year after the operation. Thirty (30) patients were assessed for Genetic Addiction Risk Severity (GARS), which analyzes neurogenetic polymorphisms involved in addiction and reward deficiency. Genetic and psychosocial data collected before the operation were correlated with weight loss data, including changes in weight, body mass index (BMI), and percent of expected weight loss (%EWL). Results examined correlations between individual gene risk alleles, 1-year body weight data, and psychosocial trait scores. Spearman's correlations revealed that the OPRM1 (rs1799971) gene polymorphism had significant negative correlation with 1-year weight (rs = -0.4477, p < 0.01) and BMI (rs = -0.4477, p < 0.05). In addition, the DRD2 risk allele (rs1800497) was correlated negatively with BMI at 1 year (rs = -0.4927, p < 0.05), indicating that one risk allele copy was associated with lower BMI. However, this allele was positively correlated with both ∆Weight (rs = 0.4077, p < 0.05) and %EWL (rs = 0.5521, p < 0.05) at 1 year post-surgery. Moreover, the overall GARS score was correlated with %EWL (rs = 0.4236, p < 0.05), ∆Weight (rs = 0.3971, p < 0.05) and ∆BMI (rs = 0.3778, p < 0.05). Lastly, Food Cravings Questionnaire (FCQ) scores were negatively correlated with %EWL (rs = -0.4320, p < 0.05) and ∆Weight at 1 year post-surgery (rs = -0.4294, p < 0.05). This suggests that individuals with a higher genetic addiction risk are more responsive to weight loss treatment, especially in the case of the DRD2 polymorphism. These results should translate clinically to improve positivity and attitude related to weight management by those individuals born with the risk alleles (rs1800497; rs1799971).

Abstract
OBJECTIVE Eating expectancies (EE) are the anticipation of various benefits or detriments from eating, with mood regulation being a salient type of EE associated with eating disorders. This study examined the convergent and predictive validity of ecological momentary assessment (EMA) mood regulation EE items, including mood improvement and mood worsening EE. METHODS Thirty women with binge-eating pathology completed a 14-day EMA protocol, which included measures of mood regulation EE, affect, appetite, appearance- and body-related factors and disordered-eating behaviours. RESULTS Greater within-subjects hunger and lower within-subjects positive affect and fullness were related to elevated mood improvement EE. Higher within-subjects appearance concerns, fullness, body social comparisons and thinness pressure were associated with higher mood worsening EE. Greater within-subjects mood worsening EE predicted greater likelihood of vomiting at the subsequent time point, but there were no within-subjects associations between mood improvement EE and behaviours. Yet, greater between-subjects mood worsening EE were associated with more restraint/restriction and binge eating, and greater between-subjects mood improvement EE were associated with more binge eating. CONCLUSIONS Findings support the convergent validity of EMA mood regulation EE items. There was limited predictive validity evidence, suggesting complexities in how mood regulation EE predict behaviour in daily life.

Abstract
BACKGROUND Eating disorder recovery is a complex phenomenon. While historical understandings focused on weight and behaviours, the importance of psychological factors is now widely recognized. It is also generally accepted that recovery is a non-linear process and is impacted by external factors. Recent research suggests a significant impact of systems of oppression, though these have not yet been named in models of recovery. BODY: In this paper, we propose a research-informed, person-centered, and ecological framework of recovery. We suggest that there are two foundational tenets of recovery which apply broadly across experiences: recovery is non-linear and ongoing and there is no one way to do recovery. In the context of these tenets, our framework considers individual changes in recovery as determined by and dependent on external/personal factors and broader systems of privilege. Recovery cannot be determined by looking solely at an individual's level of functioning; one must also consider the broader context of their life in which changes are being made. To conclude, we describe the applicability of the proposed framework and offer practical considerations for incorporating this framework in research, clinical, and advocacy settings.

Testing the interaction of thinness/restriction and negative affect reduction expectancies on disordered eating behavior. Eat Behav 2022; 47:101663. [PMID: 36067649 DOI: 10.1016/j.eatbeh.2022.101663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 08/16/2022] [Accepted: 08/24/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVE Thinness/restriction expectancies (i.e., perceived rewards from thinness/dietary restriction) and negative affect reduction expectancies (i.e., beliefs that eating will reduce negative emotions) are associated with disordered eating, but have largely been studied in isolation despite evidence that individuals can endorse these expectancies simultaneously. Guided by the goal conflict model, we hypothesized that for individuals reporting high levels of one type of expectancy, stronger endorsement of the second expectancy category would be associated with more dietary restriction, binge eating, and compensatory behaviors. A secondary aim included testing an adapted goal conflict model. DESIGN Interaction effects were tested using multiple linear and negative binomial regressions. Exploratory indirect effect models tested the adapted goal conflict model. Given gender differences, hypotheses were tested separately by gender. MEASURES Participants (N = 406, 54.2% female, non-Hispanic White = 68.8%, Mage = 20.99, MBMI = 25.05) completed measures of thinness/restriction expectancies, negative affect expectancies, dietary restriction, binge eating, and compensatory behaviors (e.g., purging, laxative/diuretic use, compensatory exercise). RESULTS No statistically significant interaction of thinness/restriction and negative affect expectancies on disordered eating was observed for either the male or female sample. Main effects models revealed consistent findings across subsamples. Greater thinness/restriction expectancies were associated with more dietary restriction, binge eating, and compensatory behaviors. Greater negative affect reduction expectancies were associated with more binge eating. Exploratory indirect effect models yielded significant effects of each expectancy category on disordered eating. CONCLUSION Expectancies may be independent risk factors for disordered eating. Disordered eating prevention and intervention efforts may benefit from explicitly targeting thinness/restriction and negative affect expectancies.

Abstract
BACKGROUND There has recently been a push for recovery-focused research in the eating disorder (ED) field, starting with a consensus definition of recovery. One definition, in particular, proposed by Bardone-Cone et al. [21] has received considerable attention given its transdiagnostic nature and validation studies. However, no studies to date have elicited lived experience views of this definition. The goal of the current study was to examine perspectives on this definition of recovery from individuals with a past or present ED and to determine whether participant agreement with the model differed based on diagnostic history or current symptom severity. METHODS Sixty-two individuals (95.2% women; 91.9% White/European) participated in a 1-2 h interview aimed at capturing their perspectives on ED recovery. Transcripts were analyzed using qualitative content analysis and codebook thematic analysis to examine agreement with and thoughts on Bardone-Cone's definition of recovery, respectively. Chi-squared tests of independence and binary logistic regression were computed to determine whether agreement with the definition differed across diagnostic history and self-reported symptoms. RESULTS Although some participants indicated acceptance of the definition, the majority expressed concerns related to its categorical nature, proposed criteria, feasibility, language, and applications. There were no differences in acceptance based on diagnostic history or current symptom severity. CONCLUSION A single definition of recovery does not seem to fit individuals' lived ED experience. Future research may benefit from distinguishing between recovery as an individually-defined phenomenon and related constructs such as remission (i.e., loss of diagnosis or absence of clinical symptoms). A more comprehensive multi-faceted, and person-centered model of recovery may have merit in clinical settings.

Abstract
PURPOSE OF REVIEW Reward-related processes may represent important transdiagnostic factors underlying eating pathology. Using the NIMH Research Domain Criteria as a guide, the current article reviews theories, behavioral and self-report assessments, and empirical findings related to reward learning in the eating disorders. RECENT FINDINGS Data from behavioral tasks suggest deficits in reinforcement learning, which may become more pronounced with increasing disorder severity and duration. Self-report data strongly implicate positive eating and thinness/restriction expectancies (an element of reward prediction error) in the onset and maintenance of eating pathology. Finally, self-report measures of habit strength demonstrate relationships with eating pathology and illness duration; however, behavioral task data do not support relationships between eating pathology and a propensity towards general habit development. Existing studies are limited, but provide preliminary support for the presence of abnormal reward learning in eating disorders. Continued research is needed to address identified gaps in the literature.

Abstract
Disordered eating is highly prevalent on college campuses and is associated with a host of negative outcomes. To better understand the nature of disordered eating, it is important to examine motivational processes that guide eating behavior. Participants: Participants were a diverse sample of 1,589 college students (80.4% females; Mage=22.2 years, SD = 5.27). Methods: This study examined anxiety sensitivity, a transdiagnostic vulnerability factor, as a predictor of eating expectancies. Results: Results indicated that higher levels of anxiety sensitivity was associated with greater levels of expectancies of eating to help manage negative affect, expectancies of eating to alleviate boredom, and expectancies of eating to lead to feeling out of control. Results were observed over and above variance accounted for by gender, race/ethnicity, and negative affectivity. Conclusions: These findings suggest that college students with higher anxiety sensitivity may have a greater risk for maladaptive eating expectancies.

Abstract
Eating expectancies, or learned expectations that an individual has about eating, prospectively predict eating disorder (ED) symptoms. Most studies examining eating expectancies have focused on one or two eating expectancies and their relation with bulimic symptoms. In addition, these studies have been conducted mostly in women. Thus, it is unclear whether: 1) associations between eating expectancies and ED symptoms vary between men and women, and 2) extend to ED symptoms other than bulimic symptoms. The current study (N = 197 undergraduate men and 246 undergraduate women) investigated sex variance in a model of eating expectancies and ED symptoms, including factors associated with ED symptoms (i.e., negative urgency, negative affect, alcohol use, drug use, and body mass index). Sex variance was tested using path analysis in a model including eating expectancies and associated factors, with excessive exercise, negative attitudes toward obesity, restricting, cognitive restraint, binge eating, purging, muscle building, and body dissatisfaction as dependent variables. Unconstrained (i.e., unconstrained paths across men and women) and constrained (i.e., constraining paths across men and women) models were tested. The unconstrained and constrained models differed significantly, indicating that the models varied by sex. For both sexes, eating expectancies were uniquely associated with ED symptoms. For men, Eating Manages Negative Affect was significantly associated with the most ED symptoms. In contrast, for women, Eating Leads to Feeling Out of Control was associated with the most ED symptoms. Previous findings regarding eating expectancies and ED symptoms in women may not generalize to men. Intervening on eating expectancies in a sex-specific way may help reduce specific ED symptoms.

Abstract
We examined the relationship between self-efficacy and three behaviours that can serve similar affect-regulatory functions (self-injury, risky alcohol use, disordered eating). We proposed that general self-efficacy would be indirectly related to each outcome, operating via emotion regulatory self-efficacy and behaviour-specific self-efficacy. A path analysis confirmed this proposal in a sample of 490 university students, who completed questionnaires assessing the constructs of interest. Emotion regulatory self-efficacy was a salient predictor of self-injury and disordered eating, evidencing both direct and indirect relationships. Self-efficacy to resist each of the behaviours was uniquely related to its target behaviour. We discuss these findings, outlining the implications for a theoretical understanding of emotion-regulatory behaviours, and offer suggestions for prevention and early intervention initiatives.

Abstract
BACKGROUND Deficits in emotion regulation are known to characterize disordered eating patterns including binge eating, purging, and dietary restraint, though much of this work has been conducted exclusively on women. Eating expectancies, or expectations regarding reinforcement from food and eating, constitute one cognitive mechanism that is thought to serve as a proximal influence on eating behavior. Previous research shows that eating to manage negative affect (a negative eating expectancy) is associated with eating pathology in women, but less is known about eating as a reward or for pleasure (a positive eating expectancy). In addition, no prior work has examined eating expectancies among men. This study examines the role of emotion regulation and eating expectancies on disordered eating in women and men. MATERIALS AND METHODS Participants were 121 female and 80 male undergraduates who completed self-report measures of emotion regulation, eating expectancies, and disordered eating. RESULTS In women, body mass index (BMI), emotion regulation, and eating to manage negative affect directly predicted disordered eating in the final multivariate model, whereas eating for pleasure or reward was inversely associated with disordered eating. However, in men, emotion regulation predicted disordered eating, but not when eating expectancies were added to the model. In the final model, only BMI and eating to manage negative affect contributed significantly to the variance in disordered eating. CONCLUSIONS These findings suggest that some correlates of eating pathology, particularly eating expectancies, may vary by gender. Future research should continue to examine gender differences in the explanatory mechanisms underlying disordered eating.
