Abstract
OBJECTIVE Food addiction (FA) shows phenotypic and diagnostic overlap with eating disorders characterised by binge eating, though it is unknown how momentary processes driving binge-eating symptoms differ by FA. The present study examined the possible moderating influence of FA severity on momentary mechanisms underlying binge-eating symptomatology using ecological momentary assessment (EMA). METHOD Adults (N = 49, mean age = 34.9 ± 12.1, cis-gender female = 77.1%) who met criteria for FA and/or binge-eating disorder completed baseline measures including the Yale Food Addiction Scale (YFAS) followed by a 10-day EMA protocol. Generalised linear mixed models assessed main effects of YFAS, momentary antecedents (affect, impulsivity, food cue exposure, appetite, and eating expectancies) and two-way interactions between YFAS and within-person antecedents. RESULTS FA severity moderated momentary associations between food cue exposure and subsequent binge-eating symptoms: the association was stronger among participants with lower but not higher YFAS scores. No other interactions were significant. CONCLUSIONS Some functional associations underlying binge-eating symptoms vary based on individuals' level of FA symptoms. Future research to further understand how observed associations may differ amongst diverse populations and over course of illness may also inform future prevention and interventions.

Abstract
Self-criticism is a trait associated with increased psychopathology, but self-criticism is also a personality state reflecting an action that people do in moments of time. In the current study, we explored factors associated with heightened self-criticism in daily life. Participants (N = 197) received five random prompts per day for one week on their mobile phones, where they reported their current affect (negative and positive affect), willpower self-efficacy, distress intolerance, degree of support and criticism from others, current context (location, activity, hunger, tiredness) and momentary self-criticism. We first demonstrated that self-criticism varies over time and across contexts, and is associated with heightened trait self-criticism. Then, using multilevel modelling, we explored the contextual factors associated with greater self-criticism. We found that self-criticism was higher when people were at home, and more tired. We also found higher self-criticism to be associated with greater negative and lower positive affect, greater distress intolerance, lower willpower and greater perceived criticism from others. In addition, self-criticism predicted subsequent distress intolerance, willpower and positive affect in lagged analyses. This study provides evidence that both environmental and psychological factors are associated with the dynamics of self-critical thoughts.

Int J Eat Disord 2024; 57:1245-1252. [PMID: 38450762 DOI: 10.1002/eat.24170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 02/02/2024] [Accepted: 02/02/2024] [Indexed: 03/08/2024]
Abstract
OBJECTIVE Appearance focused self-concept (i.e., overvaluing the importance of appearance for self-definition and self-worth) is theorized to predict dietary restraint and binge eating in the short-term (e.g., daily life). Yet, no research has examined whether appearance focused self-concept increases within-persons during a day and if such increases are linked to greater dietary restraint and binge eating for that day. We addressed this gap in knowledge. METHOD Sixty-three female university students completed four items from the Beliefs About Appearance Scale as a measure of appearance focused self-concept six times per day (9 am, 11 am, 1 pm, 3 pm, 5 pm, and 7 pm) for 14 days. Daily at 9 pm, they completed measures of dietary restraint and binge eating for that day. RESULTS Analyzing data from 555 days, latent growth curve analyses revealed a small-to-moderate linear increase in appearance focused self-concept from 9 am to 3 pm that plateaued from 3 to 7 pm. A more rapid linear increase in appearance focused self-concept from 9 am to 3 pm was associated with greater binge-eating frequency during that day, but not with dietary restraint. The findings were observed when adjusting for between-day appearance focused self-concept at 9 am, which was positively associated with dietary restraint and binge-eating frequency. DISCUSSION Findings are discussed in relation to research on appearance focused self-concept as a risk factor for disordered eating. Findings are also discussed in relation to how sociocultural factors may increase appearance focused self-concept over time. Future research should delve into the within-day dynamic interplay between appearance focused self-concept and disordered eating. PUBLIC SIGNIFICANCE Our study revealed a noteworthy increase in the importance women attach to their appearance over the course of a day, correlating with increased binge eating during that day. Additionally, heightened appearance importance at the onset of a day was associated with more dietary restraint and binge eating during that day. These findings suggest a shorter timescale for the connection between appearance importance and disordered eating than previously understood.

Abstract
Ecological momentary assessment (EMA) of binge-eating symptoms has deepened our understanding of eating disorders. However, there has been a lack of attention on the psychometrics of EMA binge-eating symptom measures. This paper focused on evaluating the psychometric properties of a four-item binge-eating symptom measure, including multilevel factor structure, reliability, and convergent validity. Forty-nine adults with binge-eating disorder and/or food addiction completed baseline questionnaires and a 10-day EMA protocol. During EMA, participants completed assessments of eating episodes, including four binge-eating symptom items. Analyses included multilevel exploratory factor analysis, computation of omega and intraclass correlation coefficients, and multilevel structural equation models of associations between contextual factors and binge-eating symptoms. A one within-subject factor solution fit the data and showed good multilevel reliability and adequate within-subjects variability. EMA binge-eating symptoms were associated with baseline binge-eating measures as well as relevant EMA eating characteristics: including greater unhealthful food and drink intake; higher perceived taste of food; lower likelihood to be planned eating; and lower likelihood of eating to occur at work/school and other locations and greater likelihood to occur at restaurants compared to home. In conclusion, the study findings support the psychometrics of a 4-item one-factor EMA measure of binge-eating symptoms.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic led to a global surge in videoconferencing use for work/study-related reasons. Although these platforms heighten exposure to one's image, the implications of videoconferencing use on body image and eating concerns remain scantly examined. This study sought to investigate, in an Australian sample, whether videoconferencing for work/study-related reasons predicted increases in body dissatisfaction (BD), urge to engage in disordered eating (DE; restrictive eating, exercise, overeating/purging), and negative mood at the state level. Participants (N = 482, 78.8% women, Mage = 20.5 years [SD = 5.3]) completed baseline demographic measures, accompanied by an ecological momentary assessment (EMA) of videoconferencing for work/study-related reasons, BD, DE urges, and negative mood six times a day for 7 days via a smartphone application. Most participants (n = 429; 89.0%) reported state-based videoconferencing use during the EMA phase. Consistent with expectations, state-based videoconferencing use was associated with an increase in state-level urges to engage in exercise. However, contrary to predictions, state-based videoconferencing use was linked to a decrease in state-level BD at the next assessment point and failed to predict negative mood and urges to engage in restrictive eating or overeating/purging at the state level. Given the simplified measure of videoconferencing use, the current research is considered preliminary and future replication and extension, using more nuanced measures, is warranted.

Abstract
OBJECTIVE Individuals with eating disorders (EDs) display elevated rates of suicidality (i.e., suicidal ideation and behaviors) as well as nonsuicidal self-injury (NSSI) (e.g., self-harm behaviors without intent to die). NSSI-and particularly the functions of NSSI-predict suicidal ideation in general samples; however, to our knowledge, the relation between NSSI functions and suicidal ideation in ED populations has been unexplored. METHOD This study examined whether specific functions of NSSI are relevant to suicidal ideation in a treatment-seeking sample of women with EDs (n = 100). Participants completed self-report measures of suicidal ideation, NSSI, and related psychopathology upon intake to an ED treatment program. RESULTS Using the four-function model of NSSI, we found that intrapersonal and interpersonal-negative reinforcement, but not interpersonal-positive reinforcement functions, were related to suicidal ideation in women with EDs. Contrary to expectations, we did not find that endorsement of multiple NSSI functions was related to increased suicide risk. DISCUSSION Findings imply that some, but not all, functions of NSSI may be relevant to suicide risk in individuals with EDs. Implications for further research are discussed.

Int J Eat Disord 2023; 56:2131-2141.

Abstract
OBJECTIVE Self-compassion has an inverse association with dietary restraint however, the mechanisms linking self-compassion and dietary restraint are not clear. This study aimed to determine to what extent self-compassion was inversely concurrently related to dietary restraint, indirectly through body-related self-conscious emotions, and to what extent trait self-compassion moderated the concurrent within-person association between body-related self-conscious emotions and dietary restraint. METHOD Data was collected from 224 Canadian university students who reported on trait self-compassion at baseline and body-related shame, guilt, envy, and embarrassment, and dietary restraint biweekly between November 2020 and August 2021. RESULTS Results from a 2-1-1 multilevel mediation model showed that trait self-compassion was indirectly concurrently related to dietary restraint through body-related shame, guilt, envy, and embarrassment. Results from the moderation model showed that there was a significant positive concurrent within-person association between body-related shame, envy, and embarrassment, but not guilt, with dietary restraint. These relationships were not moderated by trait self-compassion. DISCUSSION This study adds to our understanding of the concurrent association between body-related self-conscious emotions and dietary restraint, and the mechanisms through which self-compassion is related to dietary restraint. Given body-related self-conscious emotions were related to dietary restraint at both the within-person and between-person level, both compassion-focused interventions that aim to improve general levels of body-related self-conscious emotions and interventions that aim to overcome spikes in these emotions compared with one's usual level are warranted. PUBLIC SIGNIFICANCE STATEMENT Negative body-related self-conscious emotions were related to higher levels of dietary restraint both across individuals and within individuals over time; and may play a mechanistic role in linking self-compassion with dietary restraint. Interventions aimed at reducing negative body-related self-conscious emotions are warranted in the prevention of eating disorder psychopathology.

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
OBJECTIVES The goal of this study was to test whether interpersonal dysfunction, characterized by loneliness and/or dissatisfaction with relationships, is an imminent predictor of financial exploitation vulnerability (FEV) among adults age 50+ within a 6-month observation period. This study also tests whether FEV prospectively predicts interpersonal dysfunction. METHODS Twenty-six adults aged 50 or older completed a study involving baseline data collection and 13 follow-ups over 6 months. Linear mixed models were used for primary analyses. RESULTS After adjustment for demographic, psychological and cognitive covariates, there were between-person effects of FEV and interpersonal dysfunction across follow-ups, suggesting that those with generally higher interpersonal dysfunction compared to other participants also reported greater FEV (B(SE) = 1.09(.33), p = .003). There was a within-person effect (B(SE) = .08(.03), p = .007) of elevated interpersonal dysfunction predicting greater FEV two weeks later across all follow-ups. Within-person effect of FEV was not predictive of interpersonal dysfunction (B(SE) = .25(.15), p = .10). There was also a significant effect of age (B(SE) = -.06(.02), p = .007), such that older individuals had lower FEV throughout follow-ups. CONCLUSION Among adults age 50+, individuals with higher interpersonal dysfunction relative to others in the study reported greater FEV throughout the 6-month observation period. Increased loneliness and social dissatisfaction, relative to one's average level, predicts subsequent increases in FEV, and may be an imminent risk factor for exploitation.

Abstract
The presence of a physical or mental health issue, such as an eating disorder (ED), impacts daily activities, also known as occupations. For example, an overinvestment in body shape and weight undoubtedly can lead to an underinvestment in other, more meaningful occupations. To address ED-related perceptual disturbances, a detailed log of daily time use can pinpoint food-related occupational imbalances. This study aims to characterize the daily occupations associated with EDs. The first specific objective (SO.1) is to categorize and quantify the temporal organization of a typical day's occupations as self-reported by individuals with an ED. The second specific objective (SO.2) is to compare daily occupational time use among people with different ED types. This retrospective study based on time-use research principles was conducted by analyzing data from an anonymized secondary dataset (Loricorps's Databank). Data were collected between 2016 and 2020, from 106 participants, with descriptive analysis completed to determine the average daily time use for each occupation. A series of one-way analyses of variance (ANOVAs) were performed to compare perceived time use in each occupation for participants with different types of EDs. The outcomes show a marked underinvestment in leisure categories compared to the general population. In addition, personal care and productivity can represent the blind dysfunctional occupations (SO.1). Moreover, compared to those with binge eating disorder (BED), individuals with anorexia nervosa (AN) are significantly more invested in occupations that focus explicitly on perceptual disturbances, such as personal care (SO.2). The highlight of this study is the distinction between marked versus blind dysfunctional occupation, which offers specific avenues for clinical intervention.

Abstract
Eating disorders are severe mental illnesses characterized by the hallmark behaviors of binge eating, restriction, and purging. These disordered eating behaviors carry extreme impairment and medical complications, regardless of eating disorder diagnosis. Despite the importance of these disordered behaviors to every eating disorder diagnosis, our current models are not able to accurately predict behavior occurrence. The current study utilized machine learning to develop longitudinal predictive models of binge eating, purging, and restriction in an eating disorder sample (N = 60) using real-time intensive longitudinal data. Participants completed four daily assessments of eating disorder symptoms and emotions for 25 days on a smartphone (total data points per participant = 100). Using data, we were able to compute highly accurate prediction models for binge eating, restriction, and purging (.76-.96 accuracy). The ability to accurately predict the occurrence of binge eating, restriction, and purging has crucial implications for the development of preventative interventions for the eating disorders. Machine learning models may be able to accurately predict onset of problematic psychiatric behaviors leading to preventative interventions designed to disrupt engagement in such behaviors.

Abstract
BACKGROUND The network approach has emerged as a useful framework for conceptualizing and investigating psychopathology, including eating disorders. Network connectivity, that is, the density of the connections among network nodes, has been somewhat neglected despite its theoretical relevance. As predicted by network theory, symptom connectivity would be distinct but related to symptom severity and may be a useful clinical indicator of psychopathology as stronger and/or more diffuse connections among symptoms offer more avenues for symptom activation. This study aimed to investigate the relationship between moment-by-moment individual-level symptom connectivity and global levels of symptom severity in the context of eating disorder symptoms and experiences. METHODS A sample of 58 female undergraduate college students, mean (SD) age = 20.5 (3.1) provided data on eating disorder symptoms eight times a day over the course of 10 days. Network analyses were used to calculate the eating disorder symptoms network connectivity for each participant. In addition, participants completed survey of self-report measures of eating disorder symptom severity and trait mindfulness and body image flexibility. RESULTS Analyses revealed a moderate, positive relationship between individual network connectivity and eating disorder symptom severity. In addition, symptom connectivity predicted unique variance of symptom severity even after controlling for other clinically-relevant variables. CONCLUSIONS Individual-level network connectivity may be an important dimension of psychopathology and further work exploring the role of network connectivity is warranted. PUBLIC SIGNIFICANCE These findings suggest that symptom severity and the extent to which different eating disorder symptoms are connected are related but different dimensions. Investigating how these different dimensions play a role in eating disorder pathology could help to better understand and treat these disorders.

Abstract
INTRODUCTION Previous studies have suggested the positive influence of social support on the treatment and recovery of eating disorders (EDs). Yet, more research is needed on how objective and subjective social support differ between ED diagnostic groups using nationally representative data. Therefore, the current secondary data analysis examined associations between EDs and objective and subjective social support using data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) study. METHODS Participants completed measures of lifetime and past year diagnostic criteria for anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) and items assessing objective social support (i.e., number of close friends and close relatives) and subjective social support (i.e., perceptions of availability of support). RESULTS Compared to those without EDs, those with AN, BN, and BED had poorer subjective social support-or lower perceptions of social support. However, there were fewer differences regarding objective social support. Individuals with BN reported a lower number of close relatives compared to those without EDs and those with AN, but there were no differences in the number of close friends between ED groups. Those who experienced remission from EDs had higher perceptions of social support compared to those with past year EDs. DISCUSSION The findings show deficits in subjective social support across EDs but only lower objective social support in BN. This highlights the clinical utility of increasing perceptions of social support across EDs. The findings also show the importance of perceived social support in recovery from EDs.

Abstract
PURPOSE Anorexia nervosa (AN) and non-suicidal self-injury (NSSI) share typical onset in adolescence, greater prevalence in females and similar risk factors. Nevertheless, clinical features of eating disorders (ED) in this population are still under-investigated, especially associated to psychological features. METHODS The present study aims at comparing clinical and ED characteristics and psychopathological traits in a sample of 253 female adolescents with AN with or without NSSI and to determine possible clinical and psychological predictors on the presence of NSSI. The two groups were compared through multivariate analyses, while correlation and regression analyses were conducted to determine possible associations and predictors. RESULTS AN + NSSI group showed higher prevalence of binging-purging-type AN (p < .001), and mean higher age (p = .008) and Body Mass Index (BMI) (p = .002) than AN without NSSI group. Concerning psychological scales, AN + NSSI group showed higher scores in mostly of the sub-scale of the test Eating Disorders Inventory-3, higher scores at the scale for depression (p < 0.001) and higher scores at the three indexes of Symptom Checklist 90-Revised test, Global Severity Index (p < 0.001), Positive Symptoms total (p = .003) and Positive Symptom Distress Index (p < 0.001). No differences emerged at Children's Global Assessment Scale and at scale for evaluation of alexithymia. Regression analyses showed that a diagnosis of binging-purging-type AN (p = .001) predicts NSSI. CONCLUSION Results suggest that adolescents with AN and NSSI show peculiar clinical features with higher prevalence of binging-purging-type AN and more severe psychopathological traits than adolescents with AN without NSSI. LEVEL OF EVIDENCE Level III: Evidence obtained from cohort or case-control analytic studies.

Abstract
BACKGROUND The 26-item Eating Attitudes Test (EAT-26) is a commonly used tool to assess eating disorder risk. The purpose of this study was to examine the psychometric properties of the EAT-26 with a combined sample: (1) of adults with overweight and obesity enrolled in a behavioral weight loss program and (2) general adult sample (n = 469; age = 36.17 ± 17.83 years; female = 72.5%; white = 66.3%; obese BMI category = 58%). METHODS Rasch modeling was used to assess model-data fit, create an item-person map to evaluate relative distribution items and persons, item difficulty, and person's eating disorder (ED) risk level of the EAT-26. Differential item functioning (DIF) and rating scale functioning of the EAT-26 were also evaluated using Rasch analysis. RESULTS A total of 7 misfit items were removed from the final analysis due to unacceptable Infit and Outfit mean square residual values. The item-person map showed that the items were biased toward participants with moderate to high levels of ED risk and did not cover those who had low risk for having an ED (< - 1 logits). The DIF analyses results showed that none of the items functioned differently across sex, but 5 items were flagged based on obesity status. The six-category Likert-type rating scale did not function well indicating a different response format may be needed. CONCLUSION Several concerns were identified with the psychometric evaluation of the EAT-26 that may question its utility in assessing ED risk in individuals at low risk for ED, within samples of people who have overweight and obesity seeking weight loss treatment. The 26-item Eating Attitudes Test is a self-rated measure of eating attitudes that measures symptoms and concerns of eating disorders (ED). Very little is known about how this instrument performs differently based on individual factors like body mass index (BMI) and sex (male/female). We used an advanced measurement theory (i.e., Rasch analysis) to determine if the EAT-26 is an adequate measure to detect disordered eating in men and women of different BMIs. Results indicated that the EAT-26 was biased toward participants with moderate to high levels of disordered eating risk and did not adequately detect individuals at low risk for disordered eating. The EAT-26 did not function differently based on sex (male/female). However, five questions did function differently based on obesity status (those without obesity/ those with obesity). Finally, we observed the six-category rating scale did not function appropriately and that a new response format may be warranted. In sum, there were several issues (e.g., poor rating scale and different item functioning) with the EAT-26 and future work should develop screening tools that detect low risk of disordered eating as well as function well in adults with overweight and obesity.

Abstract
ObjectiveLoss of control (LOC) eating has been directly related to the core aspects of the psychopathology of eating disorders and to different dimensions of emotion and behavior regulation and self-criticism. This study investigates a model representing the interplay between these dimensions to understand LOC eating among a nonclinical sample.MethodsA total of 341 participants, recruited in a college campus (mean age 23.21, SD = 6.02), completed a set of self-report measures assessing LOC eating, weight suppression, psychopathology of eating disorders, depression, negative urgency, emotion regulation difficulties, and self-criticism. Path analysis modeling tested a hypothesized model with 3 paths for LOC eating as follows: (1) psychopathology of eating disorders; (2) emotion and behavior regulation; and (3) interplay between these paths.ResultsWe found goodness-of-fit indexes to our data: χ2 = 17.11, df = 10, Comparative Fit Index (CFI) = 0.99, Tucker-Lewis index (TLI) = 0.98, Root Mean Square Error Approximation (RMSEA) = 0.045, Standardized Root Mean Square Residual (SRMR) = 0.041, suggesting that: (1) participants with higher weight suppression showed higher degrees of the psychopathology of eating disorders, which was linked to higher levels of LOC eating; (2) self-criticism was a mediator between emotion regulation and depression/negative urgency; (3) self-criticism was a mediator between emotion regulation and disorder eating, which was significantly associated with LOC eating via increased negative urgency.ConclusionOur model shows that LOC eating occurs for individuals with the psychopathology of higher eating disorders who experience depressive symptoms and act rashly under distress for their inability to cope adequately with negative feelings of self-devaluation. These findings point to the importance of negative self-evaluations and feelings of inadequacy or worthlessness to understand LOC eating among college students.

Abstract
Body dissatisfaction (BD) and preoccupation with thoughts of food (PTF) are intertwined and are components of thought-shape fusion. Thought-shape fusion describes the process by which PTF lead to beliefs about weight and shape. To study thought-shape fusion in daily life and explore various transitions between BD and PTF, 30 women with binge eating completed ecological momentary assessment for 14 days. BD and PTF were assessed using continuous rating scales at each prompt. Multi-state modeling, which analyzes micro-temporal transitions between discrete states, was used to examine transitions among four states created with BD and PTF ratings. The four states included low BD/low PTF, low BD/high PTF, high BD/low PTF, and high BD/high PTF. Affect and disordered eating were examined as covariates of state transitions. Results showed high BD states were self-perpetrating, such that when in high BD states, transition to low BD states were less likely. Regarding covariates, positive affect buffered against maladaptive transitions whereas negative affect and disordered eating increased risk. Findings highlighted high BD states as influential, and negative affect and disordered eating as risk factors and positive affect as preventive. This study enhances theory of thought-shape fusion and implicates transitions from BD to PTF as possible underlying transitions.

Abstract
PURPOSE Ecological momentary assessment (EMA) studies preliminarily support the transactional model of emotion regulation in eating disorders, such that heightened stress appraisal (i.e., the cognitive evaluation of an event's demands) results in increased negative affect (NA) and subsequent binge eating (BE). However, the temporal relationships between these variables and the magnitude of stress appraisal that is clinically significant require clarification. The current study aimed to extend previous research by (1) examining the temporal relationship between stress appraisal, changes in NA, and BE using three timepoints, (2) exploring what magnitude of momentary stress appraisal results in clinically significant increases in NA and BE, and (3) characterizing what stressors are associated with clinically significant stress appraisal. METHODS 37 adult females completed an EMA protocol assessing momentary stressors, stress appraisal, NA, and BE over 2 week duration. Multilevel mediation models were used to test the study aims. RESULTS Momentary increases in stress appraisal significantly predicted binge eating through increases in NA. Stress appraisal ratings of 0.50 SD higher relative to one's average stress appraisal began to significantly predict the likelihood of BE through increases in NA, and the likelihood of BE occurrence increased with every 0.25 increments in momentary stress appraisal. Work/school stressors and interpersonal stressors were the most commonly endorsed stressors of clinically significant stress appraisal. CONCLUSION The current study supported the transactional model of emotion dysregulation in a binge eating sample and supports the use of momentary interventions at times of clinically significant stress appraisal to reduce BE risk. LEVEL OF EVIDENCE Level II, controlled trial without randomization.

Abstract
PURPOSE OF REVIEW The current report aims to summarize recent advances about the relationship between non-suicidal self-injury (NSSI) and eating disordered (ED) behaviors and highlights meaningful directions for future research. RECENT FINDINGS While there is solid evidence indicating a robust cross-sectional association between NSSI and ED behaviors, emerging evidence suggests that the temporal relationship between these behaviors may be bidirectional. Shared functions and risk factors may explain why these behaviors often co-develop. At the same time, little is still known about the psychosocial consequences of comorbid NSSI and ED engagement, and there is a lack of intervention studies that target these behaviors simultaneously. It is well-established that NSSI and ED behaviors frequently co-occur. The field should now turn to longitudinal designs to advance our understanding of the longer-term developmental and the shorter-term momentary relationship of these behaviors in daily life. Providing insight into these areas will help guide the deployment of evidence-based interventions that match the needs of clients who report comorbid NSSI and ED behaviors.
