Eating disorder-related functional impairment predicts greater depressive symptoms across one semester of college.

Eating disorder (ED) behaviors and depression are associated with numerous negative outcomes, including lower quality of life and functional impairment. College women are at elevated risk for both. Prior research indicates ED behaviors, including binge eating, self-induced vomiting, and fasting, predict increases in future depressive symptoms. However, symptom heterogeneity in EDs is common, and all disordered eating, or its associated distress, cannot be captured by the endorsement of behaviors. Impairment that results from ED behaviors may be a comparable, or stronger, predictor of depressive symptoms. We sought to characterize the longitudinal relationship between ED-related functional impairment, ED behaviors, and depressive symptoms. College-aged women [N = 304; 72 % white, mean (SD) age = 18.45 (0.88)] completed an online survey in August (baseline), and then three months later in November (follow-up). Baseline ED-related functional impairment, but not baseline ED behaviors, significantly predicted depressive symptoms at follow-up, controlling for baseline depressive symptoms, negative affect, and body mass index. Findings indicate ED-related functional impairment is a risk factor for increases in depressive symptoms across one semester of college, irrespective of ED behavior engagement, weight status, and dispositional negative affect. Intervening upon ED-related functional impairment may reduce or prevent future depressive symptoms among college-aged women.

The role of parental maladaptive emotion socialization in the risk process for negative urgency and drinking behavior in adolescence.

INTRODUCTION: Negative urgency (the tendency to act rashly when experiencing negative emotions) is a robust risk factor for a number of problem behaviors, including early adolescent drinking. Little is known about the factors that precede the development of negative urgency, and hence the full etiology of this component of risk. The current study aimed to investigate the possibility that facets of childhood maladaptive emotion socialization (the tendency for children's expressions of emotions to be met with punishment, minimized, or invoke a reaction of distress from their parents/caretakers) increases risk for the development of negative urgency and drinking behavior. METHOD: Self-report measures of negative urgency, subfacets of maladaptive emotion socialization, and drinking behavior were collected during the 2021-2022 academic year from a sample of 428 high school students (mean age = 14.7, SD = 0.09, 44% female), assessed twice over the course of a semester, reflecting a 4-month longitudinal window. RESULTS: Distress emotion socialization predicted increases in negative urgency, minimizing predicted decreases in negative urgency, and punitive did not provide significant prediction. Additionally, results found that higher levels of both negative urgency and distress emotion socialization increased adolescents' likelihood of having tried alcohol. These processes were invariant across race and gender. CONCLUSIONS: The present study may inform the future creation of prevention and intervention efforts aimed at reducing maladaptive emotion socialization and increasing adaptive emotion socialization. Successful reductions in negative urgency as a consequence of increased adaptive emotion socialization may then lead to decreases in adolescent drinking and other impulsigenic behaviors.

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.

A longitudinal test of problematic alcohol use and binge eating among college women: The moderating role of shame.

Problematic alcohol use and binge eating frequently co-occur. High levels of negative affect, negative urgency, and/or shame may increase the likelihood that problematic alcohol use and binge eating co-occur over time. OBJECTIVE: Examine (1) the temporal relationship between problematic alcohol use and binge eating among college women, who are at high risk for both, and (2) the additive and moderating effects of shared, emotion-based risk factors in models involving both problematic alcohol use and binge eating. METHOD: In n = 302 college women assessed at two time points across 8 months, we used hierarchical linear regression to investigate our objectives. RESULTS: Baseline problematic alcohol use and baseline shame independently predicted increases in follow-up binge eating, controlling for baseline binge eating. In addition, the interaction between problematic alcohol use and shame accounted for further variance in subsequent binge eating (the influence of baseline problematic alcohol use on follow-up binge eating was stronger at higher levels of baseline shame). The reciprocal relationship was not significant: baseline binge eating did not predict follow-up problematic alcohol use independently or in conjunction with risk factors. Neither negative affect nor negative urgency showed predictive effects beyond prior behavior and shame. Results support (1) problematic alcohol use as a prospective risk factor for binge eating, (2) shame as an additive predictor of binge eating, and (3) shame as a positive moderator of prediction from problem drinking. CONCLUSION: Addressing shame and problematic alcohol use may be warranted in binge eating interventions for college women.

Examining the role of urgency in predicting binge size in bulimia nervosa.

Greater binge size within bulimia nervosa is associated with elevated distress and impairment. Theoretical models posit that emotion dysregulation predicts binge eating, but little research has investigated the potential for dispositional traits that reflect difficulty in emotion regulation to predict binge size among women with bulimia nervosa. Research supports that negative urgency, the tendency to act rashly when feeling distressed, is associated with binge eating behavior among individuals with bulimia nervosa. Relatively fewer studies have explored associations between binge eating and positive urgency, the tendency to act rashly when feeling extreme positive affect. The urgency traits may predict greater binge size within bulimia nervosa. The current study sought to examine negative urgency and positive urgency as predictors of test meal intake in a sample of 50 women, n = 21 with bulimia nervosa and n = 29 healthy controls. Dispositional levels of positive urgency, negative urgency, positive affect, and negative affect were measured prior to a laboratory binge eating paradigm. Participants in the bulimia nervosa group scored higher on negative urgency, positive urgency, and negative affect than participants in the control group. Across participants, lower levels of negative affect were associated with greater test meal intake. Elevated levels of positive urgency predicted significantly greater test meal intake, but only for participants with bulimia nervosa. No other dispositional traits predicted test meal intake when the interaction of positive urgency and group was included in the model. Findings suggest positive urgency is an underappreciated, but potentially important, risk factor for greater binge size in bulimia nervosa.

Pathways of personality and learning risk for addictive behaviors: A systematic review of mediational research on the acquired preparedness model.

OBJECTIVE: The Acquired Preparedness (AP) model proposes that impulsive personality traits predispose some individuals to learn certain behavior-outcome associations (expectancies), and that these expectancies in turn influence the escalation of risky behaviors. This theory has been applied to the development of behaviors such as drinking, drug use, gambling, and disordered eating. In the current study, we aimed to summarize empirical tests of this model over the 20 years since it was proposed. METHOD: We used a descriptive approach to summarize tests of mediation across 50 studies involving n = 21,715 total participants. RESULTS: We observed a consistent effect of personality on expectancies (median effect size = .22), of expectancies on behavior (.24), and a small mediated effect (.05) of personality on behavior via expectancies. Impulsive traits that involve positive or negative affect showed the most consistent support for AP, as did positive expectancies. Most studies testing AP focused on alcohol, but research on other behaviors also showed support for AP. CONCLUSIONS: The literature appears to support a small mediated effect consistent with the AP model. Future research should continue to clarify which AP pathways are most influential in explaining risky behaviors, and supplement correlational research with experimental and quasi-experimental designs.

From protein-protein interactions to immune modulation: Therapeutic prospects of targeting Neuropilin-1 in high-grade glioma.

In the past several years there has been a marked increase in our understanding of the pathophysiological hallmarks of glioblastoma development and progression, with specific respect to the contribution of the glioma tumor microenvironment to the rapid progression and treatment resistance of high-grade gliomas. Despite these strides, standard of care therapy still only targets rapidly dividing tumor cells in the glioma, and does little to curb the pro-tumorigenic functions of non-cancerous cells entrenched in the glioma microenvironment. This tumor promoting environment as well as the heterogeneity of high-grade gliomas contribute to the poor prognosis of this malignancy. The interaction of non-malignant cells in the microenvironment with the tumor cells accentuate phenotypes such as rapid proliferation or immunosuppression, so therapeutically modulating one target expressed on one cell type may be insufficient to restrain these rapidly developing neoplasias. With this in mind, identifying a target expressed on multiple cell types and understanding how it governs tumor-promoting functions in each cell type may have great utility in better managing this disease. Herein, we review the physiology and pathological effects of Neuropilin-1, a transmembrane co-receptor which mediates signal transduction pathways when associated with multiple other receptors. We discuss its effects on the properties of endothelial cells and on immune cell types within gliomas including glioma-associated macrophages, microglia, cytotoxic T cells and T regulatory cells. We also consider its effects when elaborated on the surface of tumor cells with respect to proliferation, stemness and treatment resistance, and review attempts to target Neuroplin-1 in the clinical setting.

Maladaptive Emotion Socialization as a Risk Factor for the Development of Negative Urgency and Subsequent Problem Drinking.

AIMS: Negative urgency, which refers to the tendency to act rashly when experiencing intense negative emotions, consistently serves as a robust predictor of problem drinking and other maladaptive behaviors. However, very little is known about the factors that influence the development of negative urgency itself. Although urgency theory suggests that environment and temperament interact to increase risk for the development of urgency, few studies, to date, have examined environmental risk for urgency. METHOD: In a cross-sectional sample of 518 adults recruited from Amazon Mturk, the current study began the investigation of the role of childhood maladaptive emotion socialization (MES) in risk for negative urgency and the possibility that negative urgency mediates the relationship between MES and problem drinking via self-report measures completed online. Data were analyzed using structural equation modeling. RESULTS: Individual differences in childhood MES, reported retrospectively, did predict increased present-day negative urgency. In addition, results were consistent with the possibility that negative urgency mediates the relationship between MES and problem drinking when considered concurrently with trait negative affect. CONCLUSIONS: Successful identification of early environmental predictors of negative urgency may provide useful targets for intervention efforts aimed at reducing or preventing the development of negative urgency and, subsequently, problem drinking. Further longitudinal investigations are needed to better examine these processes as they develop.

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.

Reciprocal relations between body dissatisfaction and excessive exercise in college women.

OBJECTIVE: Body dissatisfaction elevates the risk for disordered eating behaviors. Excessive exercise is prevalent among college women and associated with harm. Risk theory posits a bidirectional relationship between risk factors for disordered eating behaviors and the behaviors themselves. This study investigated the longitudinal, reciprocal relationship between body dissatisfaction and excessive exercise. PARTICIPANTS AND METHODS: College women (n = 302) assessed in August (baseline) and November (follow-up). RESULTS: Baseline body dissatisfaction significantly predicted increases in excessive exercise endorsement at follow-up, controlling for baseline excessive exercise endorsement and body mass index (BMI). Baseline excessive exercise endorsement predicted increases in body dissatisfaction at follow-up, controlling for baseline body dissatisfaction and BMI. CONCLUSIONS: Findings support the presence of a positive feedback loop between body dissatisfaction and excessive exercise; both predict increases in risk for the other, regardless of weight status. Future research should test whether this process is ongoing and predicts further distress.

Histopathology of persistent long COVID toe: A case report.

During the 2020 coronavirus (SARS-CoV-2) pandemic, several cutaneous lesions were identified, including pseudo-chilblain, vesicular, urticarial, maculopapular, and livedo/necrosis. A 59-year-old obese man with probable COVID-19 developed painful cyanosis with histopathologic capillary thrombosis of toes, and the cyanosis persisted for nearly 22 months. Shortly after initial exposure to family members with documented SARS-CoV-2, he developed upper respiratory symptoms, yet his anti-SARS-CoV-2 antibody and nasal swab RT-PCR tests were repeatedly negative. Two family members were hospitalized and one of them succumbed with documented SARS-CoV-2 pneumonia within 10 days of exposure. Biopsy specimen of the distal toe 16 weeks after initial exposure showed papillary dermal capillary thrombosis with endothelial swelling, telangiectasia, and peri-eccrine lymphocytic infiltrates resembling pernio. Overall, this is the first case of biopsy specimen of "long COVID toe" following presumed SARS-CoV-2 exposure, with a demonstration of thrombotic vasculopathy, toe cyanosis, and pernio-like pathology.

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.

How people experience and respond to their distress predicts problem drinking more than does the amount of distress.

Although broad dispositional negative affect predicts problematic alcohol use, emerging evidence suggests that individual differences in how people experience and respond to negative affect may play an important role in risk. In a sample of 358 college students assessed twice across their first year of college, the current study investigated the predictive roles of trait negative affect, affective lability (the tendency to experience rapid and intense shifts in mood), negative urgency (the tendency to act rashly when highly emotional), and problem drinking via self-report measures completed online. Data were analyzed using structural equation modeling (SEM). Individual differences in how negative affect is experienced and responded to, represented by affective lability and negative urgency, predicted problem drinking above and beyond trait negative affect, and trait negative affect had no incremental predictive power. Additionally, affective lability predicted increases in negative urgency, but the opposite was not true. A focus on characteristic ways in which individuals experience and respond to negative affect, rather than negative affect itself, may improve risk assessment and clarify the etiology of problem drinking. Continued work toward the development of comprehensive affect-based risk models for problem drinking is needed.

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.

Response to the COVID-19 Pandemic Among Posthospital Brain Injury Rehabilitation Providers.

Rehabilitation after significant acquired brain injury (ABI) to address complex independent activities of daily living and return to family and community life is offered primarily after initial hospitalization in outpatient day treatment, group home, skilled nursing, and residential settings and in the home and community of the person served. The coronavirus 2019 pandemic threatened access to care and the health and safety of staff, persons served, and families in these settings. This article describes steps taken to contain this threat by 7 leading posthospital ABI rehabilitation organizations. Outpatient and day treatment facilities were temporarily suspended. In other settings, procedures for isolation, transportation, cleaning, exposure control, infection control, and use of personal protective equipment (PPE) were reinforced with staff. Visitation and community activities were restricted. Staff and others required to enter facilities were screened with symptom checklists and temperature checks. Individuals showing symptoms of infection were quarantined and tested, as possible. New admissions were carefully screened for infection and often initially quarantined. Telehealth played a major role in reducing direct interpersonal contact while continuing to provide services both to outpatients and within facilities. Salary, benefits, training, and managerial support were enhanced for staff. Despite early outbreaks, these procedures were generally effective, with preliminary initial infections rates of only 1.1% for persons served and 2.1% for staff. Reductions in admissions, services, and unanticipated expenses (eg, PPE, more frequent and thorough cleaning) had a major negative financial effect. Providers continue to be challenged to adapt rehabilitative approaches and to reopen services.

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.

An examination of negative urgency and other impulsigenic traits in purging disorder.

There is extensive evidence for the clinical significance of Purging Disorder (PD), an eating disorder characterized by recurrent purging behavior (self-induced vomiting, laxative use, and diuretic use) in the absence of binge eating and low weight (Smith, Crowther, & Lavender, 2017). Research on the personality profile of PD is still developing but evidence supports an association with impulsivity (Brown, Haedt-Matt, & Keel, 2011). The personality underpinnings of impulsive behavior include several different impulsigenic traits. To investigate personality contributors to impulsive behavior among women with PD, we compared 31 women with PD to 57 women with bulimia nervosa (BN) and 31 healthy control women on four impulsigenic traits: negative urgency, lack of premeditation, lack of perseverance, and sensation seeking. Compared to healthy controls, women with PD reported significantly greater levels of negative urgency, but no significant differences on the other traits. Compared to BN, PD was associated with significantly lower levels of negative urgency, but no other significant differences. Compared with controls, women in the BN group had significantly higher scores on lack of premeditation and lack of perseverance, but no significant difference on sensation seeking. Findings indicate negative urgency is a potentially important personality trait for distinguishing those with PD.

Racial/ethnic differences in the time-varying association between alcohol expectancies and drinking during the transition from childhood to adolescence.

Alcohol expectancies are important determinants of adolescent drinking, but this relationship may differ based on race/ethnicity. This study used time-varying effect modeling to examine racial/ethnic differences in positive and negative alcohol expectancies and their relationship with drinking among White, African American, and Hispanic youth. Youth reported alcohol expectancies and drinking frequency from 5th grade to 10th grade. African Americans initially endorsed higher positive alcohol expectancies than Whites, but the relationship with drinking was stronger among Whites. Hispanic youth reported slightly higher negative alcohol expectancies in high school, but the relationship between negative expectancies and alcohol use was comparable across groups. The effect of expectancies on alcohol use outcomes may be more robust for Whites, which warrants investigation of risk factors for minority youth.

Factor structure, measurement and structural invariance, and external validity of an abbreviated youth version of the UPPS-P Impulsive Behavior Scale.

The current study examines the measurement properties and validity of a novel, abbreviated youth version of the UPPS-P Impulsive Behavior Scale that was developed to maintain measurement consistency with the existing adult short form. Specifically, we examined this scale's (a) factor structure; (b) measurement and structural invariance across four demographic characteristics: gender, ethnicity, household income, and parental education; and (c) correlates using a subset of 4,521 preadolescent (9- and 10-year old) children (53% male) from the baseline wave of the Adolescent Brain and Cognitive Development (ABCD) study, a large, community-based sample. Our findings supported a correlated 5-factor model, as well as a hierarchical model that recaptured the covariation among these 5 lower-order factors in three higher-order factors. Both of these models are consistent with the commonly observed structure of the UPPS-P among adults. We established measurement invariance across all demographic characteristics. Finally, our UPPS-P scales evidenced good convergent and discriminant validity with a broad swath of theoretically relevant external criteria, including self- and parent-reported personality and psychopathology, as well as lab-based neurocognitive tasks. Our findings indicate that we can assess multidimensional impulsivity in children reliably and validly by means of self-report, allowing assessment of this critical domain at early stages of development. We hope that this measure will facilitate the study of impulsivity in large-scale samples to begin to understand the evolution and long-term consequences of impulsivity.

Affective Risk for Problem Drinking: Reciprocal Influences Among Negative Urgency, Affective Lability, and Rumination.

BACKGROUND: Affective disturbances have long been implicated in the onset and maintenance of problematic alcohol use. Affective risk theory for problem drinking has moved beyond early documentation that negative affect broadly confers risk to models specifying specific affectbased risk processes. OBJECTIVE: This paper provides a theory-driven review of recent literature on the role of affect-based factors in the etiology of problematic alcohol use. First, we review recent advances in the understanding of affect-based risk for problem drinking. Second, we highlight the importance of three specific affect-based risk factors: urgency, affective lability, and rumination. Third, we offer hypotheses regarding the reciprocal relationships between specific risk factors and drinking problems. Finally, we suggest possible avenues for future research. CONCLUSION: Recent advances in the understanding of reciprocal prediction between affect-based risk factors and problem drinking have set the stage for important new avenues of investigation into the risk process. Affect-based risk processes appear to influence each otherover time, and they influence and are influenced by problem drinking. Further understanding of these processes will pave the way for a new generation of intervention strategies.
