A case for integrating self-compassion interventions targeting shame and self-criticism into eating disorder treatment: Commentary on Paranjothy and Wade.

Paranjothy and Wade's (2024) meta-analysis revealed that disordered eating was robustly and consistently associated with greater self-criticism and lower self-compassion across samples. It is well known that even evidence-based treatments for eating disorders (EDs) do not produce long-lasting effects for many patients. Additionally, it is unclear whether existing "mainstream" evidence-based ED treatments effectively reduce shame and self-criticism and increase self-compassion, even when they intend to do so. In this commentary, we assert that Paranjothy and Wade's (2024) findings should inform the integration of self-compassion interventions within ED treatment. We argue that shame, a related but distinct construct, should be strongly considered as a primary intervention target in ED interventions that seek to reduce self-criticism and increase self-compassion. We hypothesize that directly addressing shame and bolstering self-compassion at the start of ED treatment may foster higher engagement and more durable effects. We introduce the potential for adjunctive self-compassion interventions to reduce shame and self-criticism, and enhance self-compassion, alongside or within existing ED treatments. Because self-criticism and shame are shared correlates of EDs and commonly co-occurring psychopathology, we contend with the possibility that self-compassion interventions may produce transdiagnostic effects. Shame, self-criticism, and self-compassion are important intervention targets to explore in future research.

Longitudinal transactions between negative urgency and fasting predict binge eating.

Fasting and negative urgency (the disposition to act rashly when distressed) are risk factors for binge eating. It may be that each influences the other over time to predict binge eating. OBJECTIVE: This study tested whether (1) fasting predicts binge eating through negative urgency, and (2) negative urgency predicts binge eating through fasting. METHOD: Path analysis and mediation tests were used to investigate objectives in n = 302 college women assessed three times over eight months. We controlled for each variable at the previous time point, and concurrent negative affect and body mass index at each time point. RESULTS: Time 1 (T1) fasting predicted elevated negative urgency three months later at Time 2 (T2) and T2 negative urgency predicted increases in binge eating five months later at Time 3 (T3). T2 negative urgency mediated the relationship between T1 fasting and T3 binge eating. T1 negative urgency predicted increases in T2 fasting, which then predicted increases in T3 binge eating. T2 fasting mediated the relationship between T1 negative urgency and T3 binge eating. DISCUSSION: Findings suggest fasting and negative urgency transact to predict binge eating among college women. Interventions targeting negative urgency may prevent or reduce both fasting and binge eating.

LGBTQ+ outpatients present to eating disorder treatment earlier and with more severe depressive symptoms than cisgender heterosexual peers.

Community evidence indicates high eating disorder (ED) and comorbid symptom severity among LGBTQ+ compared to cisgender heterosexual (CH) individuals. Little is known about such disparities in ED treatment samples, especially in outpatient treatment. We aimed to descriptively characterize and investigate baseline group differences in symptom severity between LGBTQ+ and CH ED outpatients at treatment intake. Data from 60 (22.3%) LGBTQ+ and 209 (77.7%) CH ED outpatients were used to examine: (1) demographic and diagnostic differences; (2) differences in ED, depressive, and emotion dysregulation symptoms. Objectives were tested using Fisher-Freeman-Halton exact and independent samples t-tests, and analyses of covariance adjusted for age and diagnosis, respectively. Most LGBTQ+ outpatients were bisexual (55.2%), and 6.5% identified as transgender and non-binary. LGBTQ+ outpatients presented to treatment at younger ages (Mean Difference [MD] = -3.39, p = .016) and reported more severe depressive symptoms (MD = 5.73, p = .004) than CH patients, but endorsed similar ED symptom and emotion dysregulation severity. Groups did not differ in other demographic or diagnostic characteristics. LGBTQ+ individuals may develop more severe depression and similarly severe EDs at earlier ages but seek outpatient care sooner than CH peers. Managing depressive symptoms may be particularly important for LGBTQ+ ED patients.

Preliminary associations of body weight, weight bias, and dietary restriction with eating disorder diagnosis in women experiencing food insecurity.

Understanding the co-occurrence of food insecurity and eating disorders is a pressing concern. Several factors have been hypothesized to increase risk for eating disorders in women with food insecurity including dietary restriction, body weight, and weight-related bias, but few studies have tested these factors simultaneously to determine which are associated most strongly with eating disorder status. We tested cross-sectional associations of dietary restriction, current body mass index (BMI), weight suppression (i.e. the difference between current weight and highest weight), and weight bias with eating disorder diagnosis in a sample of 99 self-identified women with current food insecurity (54% White; mean [SD] age = 40.26 [14.33] years). Participants completed two virtual study visits consisting of electronic questionnaires and interviews. A binary logistic regression model was conducted to test relations between the hypothesized correlates and eating disorder diagnostic status in the past 12 months, controlling for age, food insecurity severity, and body dissatisfaction. Higher levels of weight suppression and weight bias, but not current BMI, were significantly associated with the presence of an eating disorder. Contrary to our hypothesis, greater dietary restriction was associated with lower likelihood of eating disorder diagnosis. Results suggest high levels of weight bias and weight suppression characterize women with food insecurity who meet criteria for an eating disorder. Women who experience food insecurity and have lost a relatively great deal of weight and/or hold biases about high weight should be screened for eating pathology in clinical settings.

East Tennessee older women's perceptions of Medicare, Medicaid, and related health policies.

Older women face unique challenges regarding health disparities. This study aims to provide an understanding of older women's perceptions and situated experiences regarding the gendered health disparities they face, which are characterized by the policies related to older women's health and the geopolitical and social norms in which they live. The purpose of this project is to provide policy and decision-makers with insights and a better understanding of older women's experiences and perceptions of the policies that impact their health and healthcare. The data for this study was collected through semi-structured interviews with twelve women in Appalachian East Tennessee. Areas examined include: the women's perceived impact of federal, state, and local policies on the participants, particularly of Medicare and Medicaid; the role of social norming and health narratives, particularly stigmatization, discrimination, and health marginalization of older women; and the role of place and place-based drivers on these areas. This study sought to determine if these factors impact the participants' awareness or lack of awareness of policies related to older women. Findings showed that older women in East Tennessee lacked knowledge of health policies, that older women perceive systemic and individual discrimination in policymaking, clinical care, and health research, and that they perceive that place-based drivers have impacted their access to healthcare. These findings have implications for policymaking and intervention design in co-production with older women in order to mitigate older women's health disparities.

Comorbid eating, depressive, and anxiety psychopathology is associated with elevated shame in women with food insecurity.

OBJECTIVE: To compare participants with current food insecurity and different psychopathology profiles on shame, guilt, anxiety, and depression using a cross-sectional design. METHOD: Women with current food insecurity (n = 99; 54% White) were placed into four groups based on their endorsement of symptoms of psychopathology: eating disorder with depression/anxiety comorbidity (ED-C group; n = 17), depression/anxiety only (Depression/anxiety group; n = 34), eating disorder only (ED group; n = 12), and No-diagnosis group (n = 36). Groups were compared on self-report measures of shame, guilt, depression, and anxiety using analysis of covariance. RESULTS: The presence of an eating disorder was associated with quadruple the risk of screening positive for comorbid depression and anxiety. The ED-C group reported elevated shame relative to the ED and No-diagnosis groups. The ED-C group reported the highest levels of anxiety, followed by the Depression/anxiety group, and the ED and No-diagnosis groups. DISCUSSION: The presence of an eating disorder with comorbidity among women with food insecurity is associated with heightened shame. Given shame's status as a transdiagnostic predictor of psychopathology, it may serve as a putative mechanism underlying the relationship between food insecurity and eating disorder comorbidity. PUBLIC SIGNIFICANCE STATEMENT: Women with food insecurity and an ED were more likely to also screen positive for depression and/or anxiety than women with food insecurity and no ED. Overlap between ED, depression, and anxiety was associated with elevated shame, a harmful, maladaptive emotion with negative psychosocial consequences.

Increases in shame following binge eating among women: Laboratory and longitudinal findings.

This multi-method, two-study investigation tested the hypothesis that, controlling for guilt and negative affect, shame increases following binge eating. Support for this hypothesis constitutes the first step in testing the theory that shame mediates the link between binge eating and comorbid psychopathology. Study 1 employed a laboratory binge-eating paradigm in n = 51 women [21 with bulimia nervosa, 30 controls]. Study 2 employed a naturalistic test of prospective relationships among binge eating, shame, guilt, and negative affect in n = 302 college women over three months. In Study 1, women with bulimia nervosa reported increases in shame that were not explained by changes in guilt or negative affect, following laboratory binge eating, compared with controls. In Study 2, baseline binge eating predicted increased shame at follow-up independently of guilt and negative affect. Should shame prove to mediate the link between binge eating and comorbid disorders, interventions to reduce shame may be useful for those who binge.

Need for Improved Collection and Harmonization of Rural Maternal Healthcare Data.

Representation in data sets is critical to improving healthcare for the largest possible number of people. Unfortunately, pregnancy is a very understudied period of time. Further, the gap in available data is wide between pregnancies in urban areas versus rural areas. There are many limitations in the current data that is available. Herein, we review these limitations and strengths of available data sources. In addition, we propose a new mechanism to enhance the granularity, depth, and speed with which data is made available regarding rural pregnancy.

The interaction between affective lability and eating expectancies predicts binge eating.

Both affective lability and eating expectancies have been found to predict binge eating. There is the additional possibility that the joint effect of affective lability and eating expectancies incurs further risk: perhaps expectancies for affective relief from eating operate more strongly in those experiencing frequent, rapid shifts in emotion. In the current study, we tested whether such a joint effect predicts binge eating prospectively in college students. We assessed affective lability, eating expectancies, and binge eating in 358 college students at two time points during the first year of college (e.g., December and April). The interaction of affective lability and eating expectancies in December predicted binge eating 4 months later in April. The influence of eating expectancies on binge eating was stronger at higher levels of affective lability. Findings offer support to the hypothesis that risk factors may transact to further elevate risk for eating disorder behaviors.Clinical implicationsThe interaction of affective lability and eating expectancies predicts binge eatingRisk factors may interact to further increase binge eatingIdentification of co-occurring risk factors may have vital treatment implications.

Affect-Based Problem Drinking Risk: The Reciprocal Relationship between Affective Lability and Problem Drinking.

AIMS: Negative affect has been implicated in risk for the development of problematic drinking behavior. Furthermore, there is evidence for reciprocal relationships between negative affect and problem drinking, such that engagement in problem drinking also predicts increases in negative affect. However, affective models of risk often fail to consider affective lability-the experience of rapidly changing mood. Although affective lability appears to increase risk for problem drinking, it is unknown if this relationship persists above and beyond other affect-related constructs (e.g. depression, anxiety) and if it is reciprocal in nature. Accordingly, we used a longitudinal survey design to examine (a) if affective lability predicts problem drinking above and beyond depression and anxiety and (b) if affective lability and problem drinking demonstrate a reciprocal relationship. METHODS: First-year college students (n = 358) participated in a three wave longitudinal study. We constructed a structural equation model (SEM) of a random intercept cross-lagged panel model to test our hypotheses. RESULTS: Consistent with our hypotheses, affective lability predicted increases in problem drinking while anxiety and depression did not. Problem drinking and affective lability demonstrated a reciprocal relationship in which increases in one predicted increases in the other at subsequent time points. This relationship was present beyond the predictive effects of anxiety or depression. CONCLUSIONS: Affective lability appears to be an important affect-based predictor of problem drinking, and there may be a reciprocal, risk-enhancing relationship between affective lability and problem drinking.Components of negative affect, such as depression or anxiety, have been shown to predict risk for problem drinking, and vice versa. A less considered construct, affective lability, predicted problem drinking while anxiety and depression did not add any predictive power. Problem drinking and affective lability also appeared to demonstrate a reciprocal relationship.

The General Factor of Psychopathology.

An important advance in understanding and defining mental disorders has been the development of empirical approaches to mapping dimensions of dysfunction and their interrelatedness. Such empirical approaches have consistently observed intercorrelations among the many forms of psychopathology, leading to the identification of a general factor of psychopathology (the p factor). In this article, we review empirical support for p, including evidence for the stability and criterion validity of p. Further, we discuss the strong relationship between p and both the general factor of personality and the general factor of personality disorder, substantive interpretations of p, and the potential clinical utility of p. We posit that proposed substantive interpretations of p do not explain the full range of symptomatology typically included in p. The most plausible explanation is that p represents an index of impairment that has the potential to inform the duration and intensity of a client's mental health treatment.

Transactions among thinness expectancies, depression, and binge eating in the prediction of adolescent weight control behaviors.

OBJECTIVE: Binge eating, the transdiagnostic risk associated with depression, and the eating disorder-specific risk associated with expectancies for reinforcement from thinness have been identified as risk factors for the development of weight control behaviors. The purpose of this study was to examine if these risk factors transact to further predict risk in youth. METHOD: Binge eating, depressive symptoms, thinness expectancies, and weight control behaviors were assessed in 1,758 adolescents three times during the transitional period between middle school and high school. We tested six different possible transactional processes. RESULTS: Mediation tests demonstrated that both 8th grade binge eating and 8th grade depressive symptoms predicted 10th grade weight control behaviors through their predictive influence on thinness expectancies in 9th grade. However, our results were not consistent with a mediational process in which 8th grade thinness expectancies predicted 9th grade depression to further predict 10th grade weight control behaviors. No interactions among binge eating, depressive symptoms, or thinness expectancies predicted weight control. Results did not differ between girls and boys. DISCUSSION: Thinness expectancies appear to mediate the predictive influence of binge eating and depressive symptoms on risk for engaging in weight control behaviors. These results add to theoretical understanding of risk and suggests potential intervention pathways for clinicians.

Transactions between early binge eating and personality predict transdiagnostic risk.

Psychiatric comorbidities are prevalent in youth eating disorders. In a sample of 1,906 youth from the United States (49.2% female), followed from elementary school into high school, we found support for a model to help explain this comorbidity. Endorsement of binge eating in fifth grade (elementary school) predicted increases in negative urgency, negative affect, and lack of planning in seventh grade (middle school). In turn, seventh grade negative urgency predicted increases in 10th grade (high school) externalizing dysfunction (binge eating, alcohol use problems, and smoking) and internalizing dysfunction (depressive symptoms). Seventh grade negative affect predicted increases in 10th grade binge eating and depressive symptoms. Seventh grade lack of planning predicted increases only in 10th grade externalizing behaviours. Early engagement in binge eating may elevate risk for multiple forms of dysfunction, at least in part due to its prediction of high-risk personality change in middle school.

Elevated vasopressin in pregnant mice induces T-helper subset alterations consistent with human preeclampsia.

The pathogenesis of preeclampsia (PreE), a hypertensive disorder of pregnancy, involves imbalanced T helper (TH) cell populations and resultant changes in pro- and anti-inflammatory cytokine release. Elevated copeptin (an inert biomarker of arginine vasopressin (AVP)), secretion precedes the development of symptoms in PreE in humans, and infusion of AVP proximal to and throughout gestation is sufficient to initiate cardiovascular and renal phenotypes of PreE in wild-type C57BL/6J mice. We hypothesize that AVP infusion in wild-type mice is sufficient to induce the immune changes observed in human PreE. AVP infusion throughout gestation in mice resulted in increased pro-inflammatory interferon γ (IFNg) (TH1) in the maternal plasma. The TH17-associated cytokine interleukin (IL)-17 was elevated in the maternal plasma, amniotic fluid, and placenta following AVP infusion. Conversely, the TH2-associated anti-inflammatory cytokine IL-4 was decreased in the maternal and fetal kidneys from AVP-infused dams, while IL-10 was decreased in the maternal kidney and all fetal tissues. Collectively, these results demonstrate the sufficiency of AVP to induce the immune changes typical of PreE. We investigated if T cells can respond directly to AVP by evaluating the expression of AVP receptors (AVPRs) on mouse and human CD4+ T cells. Mouse and human T cells expressed AVPR1a, AVPR1b, and AVPR2. The expression of AVPR1a was decreased in CD4+ T cells obtained from PreE-affected women. In total, our data are consistent with a potential initiating role for AVP in the immune dysfunction typical of PreE and identifies putative signaling mechanism(s) for future investigation.

The Occurrence and Covariation of Binge Eating and Compensatory Behaviors Across Early to Mid-Adolescence.

The purpose of this study was to examine the occurrence and covariation of four eating disorder behaviors across the elementary, middle, and high school years. In a sample of 1,906 youth measured over 5 years at nine time points, from the past year of elementary school through the second year of high school, binge eating, purging (self-induced vomiting), compensatory exercise, and fasting behavior were assessed by self-report. Over the 5-year period, rates of binge eating and purging increased but rates of compensatory exercise and fasting decreased. Girls and boys did not differ in their rates of engagement in any of the behaviors. Within time, the behaviors covaried modestly. Health-care professionals are advised to assess each behavior individually, rather than base interventions on the presence or absence of a diagnosable eating disorder. Gender should not be a basis for assessing for the presence of any of these behaviors.

Bidirectional Relations of Impulsive Personality and Alcohol Use Across Three Waves of Data Collection.

OBJECTIVE: To explore the bidirectional relations between alcohol use and three impulsive personality traits, to advance understanding of risk processes. PARTICIPANTS: 525 college students (mean age = 18.95 years) recruited in August 2008 and 2009 and followed up annually for three years. METHODS: Personality and past/current substance use were assessed. RESULTS: T2 sensation seeking mediated the predictive relationship between T1 and T3 alcohol use, and T2 alcohol use mediated the predictive relationship between T1 and T3 sensation seeking. In addition, T2 alcohol problems mediated the predictive relationship between T1 alcohol use and T3 negative urgency. CONCLUSIONS: Findings support a bidirectional relationship between sensation seeking and alcohol use, and drinking anticipates drinking problems, which predict increases in negative urgency. For some individuals, there appears to be an ongoing process of increased risk in the form of increases in both drinking and high-risk personality traits.

Developmental trajectories of compensatory exercise and fasting behavior across the middle school years.

Compensatory exercise and fasting behavior, in the absence of binge eating and purging, appear to be important eating disorder behaviors that are associated with dysfunction, but little is known about these behaviors in youth. We studied the trajectories of their development in non-binge eating and non-purging girls during early adolescence. Using a longitudinal design, we assessed 564 girls six times over the three years of middle school (grades 6 through 8) and developed trajectories specifying different developmental patterns in relation to the behaviors. Prior to this period, when the girls were in 5th grade (elementary school), we assessed risk factors to predict girls' subsequent trajectory group membership. Compensatory exercise trajectory groups included a non-engagement group, a group that increased in the behavior, and a group that decreased in the behavior. There were two fasting trajectory groups, one consistently engaging in the behavior and the other consistently not. Elementary school levels of depression, eating expectancies, and thinness expectancies predicted subsequent trajectory group membership. Risk for compensatory exercise and fasting should be evaluated as early as in 5th grade. Targeted interventions should focus on girls in late elementary school or middle school, as this appears to be a critical developmental and maintenance period for compensatory exercise and fasting behavior.

Nonsuicidal Self-injury as a Risk Factor for Purging Onset: Negatively Reinforced Behaviours that Reduce Emotional Distress.

Both nonsuicidal self-injury (NSSI) and purging behaviour are thought to involve harm to the self. The acquired capability for self-harm model holds that engaging in one self-harming behaviour increases the capability to tolerate harm to the self, thus increasing risk for engaging on other such behaviours. In addition, both behaviours are thought to serve the similar function of relief from distress. We thus tested whether engagement in one of these behaviours predicts the subsequent onset of the other. In a longitudinal design, 1158 first-year college women were assessed for purging and NSSI at two time points. Engagement in NSSI at time 1 predicted the college onset of purging behaviour 9 months later (OR = 2.20, p < .04, CI = 1.07-4.19) beyond prediction from time 1 binge behaviour, and purging behaviour at time 1 predicted the subsequent onset of NSSI (OR = 6.54, p < .01, CI = 1.71-25.04). These findings are consistent with the acquired capability for harm model and with the possibility that the two behaviours serve a similar function.

Commentary: An exemplar of progress in understanding complex disorders - reflections on what we have learned about eating disorders (Culbert et al., 2015).

A number of recent advances in eating disorders research have helped clarify the nature of risk for the development of such disorders. Culbert et al. () provide an empirical and thoughtful review of these recent advances. The authors identified empirically established risk factors in each of several categories of risk for eating disorders: genetic influences, neurotransmitter activity, hormones, personality, and sociocultural influences. We highlight three implications of their review. First, the review can serve as an important asset to eating disorder researchers, both substantively, by providing a comprehensive account of empirically supported risk processes; and methodologically, by highlighting good standards of evidence for acceptance of a candidate risk factor. Second, eating disorder risk is increased by both transdiagnostic and eating disorder-specific factors; there is a need to understand how these types of factors transact with each other. Third and most important, we highlight the importance of Culbert et al.'s advocacy for the development of theoretical models, and empirical tests of those models that specify transactions among different types of risk factors, such as those based on genetic, neurobiological, personality, and social processes.

siSPOTR: a tool for designing highly specific and potent siRNAs for human and mouse.

RNA interference (RNAi) serves as a powerful and widely used gene silencing tool for basic biological research and is being developed as a therapeutic avenue to suppress disease-causing genes. However, the specificity and safety of RNAi strategies remains under scrutiny because small inhibitory RNAs (siRNAs) induce off-target silencing. Currently, the tools available for designing siRNAs are biased toward efficacy as opposed to specificity. Prior work from our laboratory and others' supports the potential to design highly specific siRNAs by limiting the promiscuity of their seed sequences (positions 2-8 of the small RNA), the primary determinant of off-targeting. Here, a bioinformatic approach to predict off-targeting potentials was established using publically available siRNA data from more than 50 microarray experiments. With this, we developed a specificity-focused siRNA design algorithm and accompanying online tool which, upon validation, identifies candidate sequences with minimal off-targeting potentials and potent silencing capacities. This tool offers researchers unique functionality and output compared with currently available siRNA design programs. Furthermore, this approach can greatly improve genome-wide RNAi libraries and, most notably, provides the only broadly applicable means to limit off-targeting from RNAi expression vectors.
