Time-of-day and day-of-week patterns of binge eating and relevant psychological vulnerabilities in binge-eating disorder.

OBJECTIVE: The present study sought to characterize the temporal patterns of binge eating and theorized maintenance factors among individuals with binge-eating disorder (BED). METHOD: Ecological momentary assessment of 112 individuals and mixed-effects models were used to characterize the within- and between-day temporal patterns of eating behaviors (binge eating, loss of control only eating, and overeating only), positive and negative affect, emotion regulation difficulty, and food craving. RESULTS: Risk for binge eating and overeating only was highest around 5:30 p.m., with additional binge-eating peaks around 12:30 and 11:00 p.m. In contrast, loss of control eating without overeating was more likely to occur before 2:00 p.m. Risk for binge eating, loss of control only eating, and overeating only did not vary across days in the week. There was no consistent pattern of change in negative affect throughout the day, but it decreased slightly on the weekend. Positive affect showed a decrease in the evenings and a smaller decrease on the weekend. The within-day patterns of food craving, and to some extent emotion regulation difficulty, resembled the pattern of binge eating, with peaks around meal times and at the end of the night. DISCUSSION: Individuals with BED appear most susceptible to binge-eating around dinner time, with heightened risk also observed around lunch time and late evening, though the effects were generally small. These patterns appear to most strongly mimic fluctuations in craving and emotion dysregulation, although future research is needed to test the temporal relationships between these experiences directly. PUBLIC SIGNIFICANCE: It is unknown which times of the day and days of the week individuals with binge-eating disorder are most at risk for binge eating. By assessing binge-eating behaviors in the natural environment across the week, we found that individuals are most likely to binge in the evening, which corresponds to the times when they experience the strongest food craving and difficulty with regulating emotions.

The potential application of event-related potentials to enhance research on reward processes in eating disorders.

OBJECTIVE: Reward-related processes have been posited as key mechanisms underlying the onset and persistence of eating disorders, prompting a growing body of research in this area. Existing studies have primarily utilized self-report, behavioral, and functional magnetic resonance imaging measures to interrogate reward among individuals with eating disorders. However, limitations inherent in each of these methods (e.g., poor temporal resolution) may obscure distinct neurocognitive reward processes, potentially contributing to underdeveloped models of reward dysfunction within eating disorders. The temporal precision of event-related potentials (ERPs), derived from electroencephalography, may thus offer a powerful complementary tool for elucidating the neurocognitive underpinnings of reward. Indeed, a considerable amount of research in other domains of psychopathology (e.g., depression, substance use disorders), as well as studies investigating food reward among non-clinical samples, highlights the utility of ERPs for probing reward processes. However, no study to date has utilized ERPs to directly examine reward functioning in eating disorders. METHODS: In this paper, we review evidence underscoring the clinical utility of ERP measures of reward, as well as a variety of reward-related tasks that can be used to elicit specific ERP components with demonstrated relevance to reward processing. We then consider the ways in which these tasks/components may be used to help answer a variety of open questions within the eating disorders literature on reward. RESULTS/DISCUSSION: Given the promise of ERP measures of reward to the field of eating disorders, we ultimately hope to spur and guide research in this currently neglected area. PUBLIC SIGNIFICANCE: Abnormalities in reward functioning appear to contribute to eating disorders. Event-related potentials (ERPs) offer temporally precise measures of neurocognitive reward processing and thus may be important tools for understanding the relationship between reward and disordered eating. However, research in this area is currently lacking. This paper attempts to facilitate the use of ERPs to study reward among individuals with eating disorders by reviewing the relevant theories and methods.

Borderline personality disorder symptoms as mediational mechanisms linking childhood trauma and nonsuicidal self-injury among women with bulimia nervosa.

OBJECTIVE: Nonsuicidal self-injury (NSSI) frequently co-occurs with eating disorders, especially bulimia nervosa (BN). Theoretical models and empirical evidence show many overlapping risk factors for the onset and maintenance of NSSI and BN. However, among those with BN, it remains unclear what distinguishes those who do versus do not engage in NSSI. The primary objective of the present study was to identify factors predicting NSSI among women with BN. Specifically, we tested four domains of borderline personality disorder as mediators between childhood trauma and NSSI. METHOD: Using structural equation modeling we tested a parallel mediation model to predict NSSI among women with BN (N = 130). Childhood trauma (measured by the Childhood Trauma Questionnaire at baseline) was the independent variable. The four parallel mediators (measured at baseline via the Diagnostic Interview for Borderlines, Revised) were lifetime negative affect, impulsive actions, atypical cognitions (e.g., odd thinking, unusual perceptual experiences, quasi-psychotic thinking), and interpersonal problems. The dependent variable was instances of NSSI during a subsequent two-week ecological momentary assessment protocol. RESULTS: Childhood trauma was significantly associated with all four mediators (all p values < .01), but only atypical cognitions predicted NSSI (p = .03). The indirect path from childhood trauma to NSSI, through atypical cognitions was significant (path coefficient = .001, SE < .001, p = .01). DISCUSSION: Among women with BN, childhood trauma was associated with atypical cognitions, which in turn predicted NSSI. Atypical cognitions may be a mechanism for NSSI in this population.

It Is Not What Happens to You But How You React to It That Matters: PTSD as a Moderator of the Association Between Trauma and Impulsive Behaviors.

ABSTRACT: We examined the moderating role of posttraumatic stress disorder (PTSD) in the association between trauma and impulsive behaviors. Adult women ( N = 97) with a history of childhood sexual abuse (CSA; n = 26), rape in adulthood ( n = 21), both CSA and adult rape ( n = 25), or no history of sexual trauma ( n = 25) completed self-report questionnaires. PTSD symptoms were positively associated with self-harm and with stealing and accident proneness, but not with sexual impulsivity. Trauma group had no independent associations with impulsive behaviors. PTSD reexperiencing symptoms interacted with trauma group such that reexperiencing symptoms were positively associated with self-harm for the two trauma groups that included CSA but not for the control and adult rape-only groups. Overall, results indicate that PTSD symptoms-more so than the occurrence of trauma itself-associate with impulsive behavior. Results highlight the importance of assessing posttraumatic symptomatology, and not just trauma occurrence, when aiming to prevent or treat impulsive behaviors.

Which Comes First? An Examination of Associations and Shared Risk Factors for Eating Disorders and Suicidality.

PURPOSE OF REVIEW: This narrative review evaluates recent literature on the associations between eating disorders and suicidality and discusses potential shared mechanisms that may account for these relationships. Additionally, the review highlights shortcomings with the literature to date and suggests avenues for future research. RECENT FINDINGS: Individuals with anorexia nervosa, bulimia nervosa, and binge eating disorder experience elevated rates of suicidality compared to the general population. Suicide risk is higher when eating disorders occur with other psychological conditions. Additionally, genetic factors, emotion dysregulation, trauma, stressful life events, and lack of body regard may have roles in the development of both eating disorders and suicidality. Much of the risk for suicidality in eating disorders appears to be driven by comorbid psychopathology and genetic factors. However, the lack of longitudinal research makes it difficult to draw conclusions about the directionality or temporality of these relations; thus, novel methods are needed.

Suicidality in adolescents and adults with binge-eating disorder: Results from the national comorbidity survey replication and adolescent supplement.

OBJECTIVE: The relation between binge-eating disorder (BED) and suicidality (i.e., suicide ideation, plan, and/or attempt) has not been studied extensively, and it is unknown whether BED is uniquely associated with suicidality when adjusting for comorbid psychopathology. Moreover, the course of suicidality in BED has not been determined and it is unknown whether BED precedes suicidality or vice versa. METHOD: A total of 10,123 adolescents and 2,980 adults from two nationally representative surveys were administered diagnostic interviews assessing psychopathology and suicidality, as well the retrospectively reported ages of onset. RESULTS: Among adults and adolescents, BED was associated with elevated odds of suicide ideation, plan, and attempt at a univariate level, but BED was not associated with elevated odds of suicidality when adjusting for comorbid psychopathology. Kaplan-Meier estimates of temporal patterns displayed that most adolescents experienced suicidality onset following BED onset, whereas most adults experienced suicidality onset prior to BED onset. DISCUSSION: BED, comorbid disorders, and suicidality share common factors and interrelations, and individuals with BED and comorbid disorders may be at particularly high risk for suicidal outcomes. The presence of BED in adolescence may serve as a marker for more severe symptomatology that precedes the occurrence of suicidality. Research is needed to understand how eating disorder symptoms, comorbid symptoms, and suicidality affect one another over time. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2017; 50:40-49).

Does the interpersonal-Psychological theory of suicide provide a useful framework for understanding suicide risk among eating disorder patients? A test of the validity of the IPTS.

OBJECTIVE: The current study tested whether the Interpersonal-Psychological Theory of Suicide (IPTS) provides a useful framework for understanding elevated suicide rates among individuals with eating disorders (EDs). METHOD: Based on predictions of the IPTS, we tested whether the combination of thwarted belongingness and perceived burdensomeness was associated with suicidal desire, and whether the combination of thwarted belongingness, perceived burdensomeness, and fearlessness about death was associated with past suicide attempts in an ED sample (n = 100). We also compared these IPTS constructs in an ED sample versus general psychiatric inpatients (n = 85) and college students (i.e., non-clinical comparison group; n = 93). RESULTS: Within the ED sample, no hypothesized interactions were found, but perceived burdensomeness was associated with suicidal desire, and perceived burdensomeness and fearlessness about death were associated with past suicide attempts. The ED and psychiatric samples had greater thwarted belongingness, perceived burdensomeness, and suicidal desire than the non-clinical comparison group. DISCUSSION: The IPTS constructs of perceived burdensomeness and fearlessness about death appear to explain some facets of suicidality among people with EDs, but overall, support for the IPTS was limited. Future research on EDs and suicidality should look beyond the IPTS and consider other biological and sociocultural factors for suicide. © 2016 Wiley Periodicals, Inc.

Using implicit attitudes of exercise importance to predict explicit exercise dependence symptoms and exercise behaviors.

OBJECTIVES: "Fast" (i.e., implicit) processing is relatively automatic; "slow" (i.e., explicit) processing is relatively controlled and can override automatic processing. These different processing types often produce different responses that uniquely predict behaviors. In the present study, we tested if explicit, self-reported symptoms of exercise dependence and an implicit association of exercise as important predicted exercise behaviors and change in problematic exercise attitudes. DESIGN: We assessed implicit attitudes of exercise importance and self-reported symptoms of exercise dependence at Time 1. Participants reported daily exercise behaviors for approximately one month, and then completed a Time 2 assessment of self-reported exercise dependence symptoms. METHOD: Undergraduate males and females (Time 1, N = 93; Time 2, N = 74) tracked daily exercise behaviors for one month and completed an Implicit Association Test assessing implicit exercise importance and subscales of the Exercise Dependence Questionnaire (EDQ) assessing exercise dependence symptoms. RESULTS: Implicit attitudes of exercise importance and Time 1 EDQ scores predicted Time 2 EDQ scores. Further, implicit exercise importance and Time 1 EDQ scores predicted daily exercise intensity while Time 1 EDQ scores predicted the amount of days exercised. CONCLUSION: Implicit and explicit processing appear to uniquely predict exercise behaviors and attitudes. Given that different implicit and explicit processes may drive certain exercise factors (e.g., intensity and frequency, respectively), these behaviors may contribute to different aspects of exercise dependence.

Examining implicit attitudes toward emaciation and thinness in anorexia nervosa.

OBJECTIVE: To determine if females with anorexia nervosa (AN) associate emaciation with beauty by examining implicit attitudes toward emaciated bodies relative to thin bodies. METHOD: Thirty women with AN and 29 healthy control women were primed by viewing images of either emaciated or thin women. Participants then completed a lexical decision task (LDT), wherein they distinguished words from nonwords as quickly and accurately as possible. Response times were measured. Real words consisted of beautiful, ugly, neutral, and positive words. Body mass index (BMI) was measured and several clinical interviews were completed, including the Eating Disorders Examination Questionnaire 4 (EDEQ-4). RESULTS: There was a significant effect of group in the emaciated condition; participants with AN responded faster to both beautiful and ugly words than control women did. Eating disorder symptom severity (as measured by the EDEQ-4 subscales) predicted the strength of the association between emaciation and beauty. DISCUSSION: At an implicit, automatic level, women with AN in this study had stronger associations between emaciation and both beauty and ugliness than control women did, suggesting that women with AN may have atypical beliefs about beauty. Thin ideal internalization is an important factor in the development and maintenance of eating disorders; the type of thin ideal being internalized may be important to consider, particularly given the extent to which pro-eating disorder websites promote idealization of emaciation. The associations found by using the LDT highlight the utility of implicit measures, particularly when conducting assessments involving sensitive or atypical beliefs.

Baseline characteristics and treatment outcomes in prescription opioid dependent patients with and without co-occurring psychiatric disorder.

BACKGROUND: Given the growing prevalence of prescription opioid dependence and the considerable rates of additional psychopathology in drug dependence, we examined the association between the presence of a co-occurring Axis I psychiatric disorder and sociodemographic and clinical characteristics in this secondary analysis of patients entering a treatment study for dependence on prescription opioids. Treatment outcomes were also compared. METHODS: Patients dependent on prescription opioids participated in a multi-site, two-phase, randomized, controlled trial to assess different lengths of buprenorphine-naloxone pharmacotherapy and different intensities of counseling (Clinicaltrials.gov identifier: NCT00316277). Among the 653 participants entering the first phase of the trial, 360 entered the second phase, receiving 12 weeks of buprenorphine-naloxone treatment; they are reported here. Half of those participants (180/360) had a current co-occurring psychiatric disorder in addition to substance dependence. RESULTS: Sociodemographic characteristics were similar overall between those with and without a co-occurring psychiatric disorder, but women were 1.6 times more likely than men to have a co-occurring disorder. On several clinical indicators at baseline, participants with a co-occurring disorder had greater impairment. However, they had better opioid use outcomes at the conclusion of 12 weeks of buprenorphine-naloxone stabilization than did participants without a co-occurring disorder. CONCLUSIONS: Prescription opioid-dependent patients with a co-occurring psychiatric disorder had a better response to buprenorphine-naloxone treatment despite demonstrating greater impairment at baseline. Additional research is needed to determine the mechanism of this finding and to adapt treatments to address this population.

Elevated interoceptive deficits in individuals with eating disorders and self-injurious thoughts and behaviors: A replication and extension.

INTRODUCTION: People with eating disorders (EDs) frequently report self-injurious thoughts and behaviors (SITBs). We aimed to replicate and extend findings demonstrating greater interoceptive deficits according to SITB severity. We predicted that interoceptive deficits would be greater among people with versus without lifetime SITBs and among those with multiple suicide attempts compared with single attempts or nonsuicidal self-injury. We also predicted that interoception would be increasingly impaired with greater current suicidality severity. METHOD: Adults (N = 118) seeking ED treatment reported current and lifetime SITBs upon admission to treatment. We used planned contrasts to compare interoceptive deficits (self-reported using the Eating Disorders Inventory) by SITB and current suicidality groups (assessed by self-report and clinical interview). RESULTS: Interoceptive deficits were greater among people with any SITB history compared to those without. People with multiple suicide attempts did not differ in interoceptive deficits from those with single attempts or only nonsuicidal self-injury. Interoceptive deficits were elevated among those with any current suicidality compared to those with no suicidal symptoms; interoceptive deficits did not differ according to severity of suicidality. CONCLUSION: Among those with EDs, interoceptive deficits are elevated among those with concurrent SITBs. Interventions aimed at improving interoception may reduce the risk for SITBs.

Past-Year Suicidal Ideation, Plans, and Attempts by Food Security Level in a Nationally Representative Sample of U.S. Adults.

OBJECTIVE: The Interpersonal Theory of Suicide posits that suicidal behavior results from thwarted belongingness, perceived burdensomeness, and capability for suicide. Considering that food insecurity (FI) may be linked to these constructs to differing extents based on severity of FI, this study examined cross-sectional associations between levels of FI and suicidal ideation, plans, and attempts in a nationally representative sample of adults in the United States. METHODS: Data for this study were collected in 2001-2003 from 5,552 participants in the National Comorbidity Survey Replication (Mage=44.8 ± 0.5 years; 53.8% female). Prevalence ratios (PRs) and 95% confidence intervals (CIs) were generated using modified Poisson regression to examine past-year ideation, plans, and attempts with intent of lethality by past-year FI level (assessed with a modified version of the Short Form U.S. Household Food Security Scale). RESULTS: After controlling for sociodemographic covariates, low food security was significantly associated with elevated prevalence of suicidal ideation, plans, and attempts (ideation: PR = 2.21, 95% CI 1.32-3.70; plans: PR = 5.42, 95% CI 2.71-10.83; attempts: PR = 5.35, 95% CI 2.38-12.03). Very low food security (i.e., more severe FI) exhibited stronger associations yet with suicidal ideation, plans, and attempts (ideation: PR = 6.99, 95% CI 4.10-11.92; plans: PR = 17.21, 95% CI 8.41-35.24; attempts: PR = 14.72, 95% CI 4.96-43.69). CONCLUSIONS: Findings indicative of a dose-response relationship between FI and suicidal ideation, plans, and attempts emphasize the need to increase reach of food assistance programs, increase availability of mental health services in food-insecure populations, and routinely screen for FI in mental health practice.

Identifying transdiagnostically relevant risk and protective factors for internalizing psychopathology: An umbrella review of longitudinal meta-analyses.

Internalizing mental disorders are highly comorbid with one another, and evidence suggests that etiological processes contributing to these disorders often overlap. This systematic umbrella review aimed to synthesize meta-analytic evidence from observational longitudinal studies to provide a comprehensive overview of potentially modifiable risk and protective factors across the depressive, anxiety, and eating disorder psychopathology domains. Six databases were searched from inception to August 2022. Only meta-analyses of longitudinal studies that accounted for baseline psychopathology (either via exclusion of baseline cases or statistical adjustment for baseline symptoms) were included. Methodological quality of meta-analyses was evaluated using the AMSTAR 2, and quality of evidence for each analysis was rated using GRADE. Study selection, quality assessment, and data extraction were conducted in duplicate by independent reviewers. The protocol for this review was registered with PROSPERO (CRD42020185575). Sixty-one meta-analyses were included, corresponding to 137 meta-analytic estimates for unique risk/protective factor-psychopathology relationships. Most potential risk/protective factors, however, were examined only in relation to depressive psychopathology. Concern over mistakes and self-esteem were the only risk and protective factors, respectively, identified as statistically significant across depressive, anxiety, and eating disorder psychopathology domains. Eight risk factors and four protective factors also emerged as having transdiagnostic relevance across depressive and anxiety domains. Results suggest intervention targets that may be valuable for preventing/treating the spectrum of internalizing psychopathology and reducing comorbidity. However, few factors were identified as transdiagnostically relevant across all three internalizing domains, highlighting the need for more research investigating similar sets of potential risk/protective factors across internalizing domains.

A Randomized Test of Interpretation Bias Modification for Perfectionism Versus Guided Visualization Relaxation Among High Perfectionistic Undergraduate Students.

Clinical perfectionism contributes to the onset and maintenance of multiple psychological concerns. We conducted a randomized, longitudinal test of the efficacy of a web-based intervention for perfectionism (specifically, cognitive bias modification, interpretation retraining; CBM-I), compared to an active treatment comparison condition (specifically, guided visualization relaxation training) for reducing perfectionism and related psychopathology. College students (N = 167) with elevated perfectionism were randomized to one of the two study conditions and were asked to complete their assigned intervention twice weekly for 4 weeks. Participants completed measures of perfectionism and psychological symptoms at baseline, 2 weeks (midway through the intervention period), 4 weeks (at the conclusion of the intervention period), and 8 weeks (1 month follow-up). CBM-I was rated as acceptable overall, though relaxation training was rated slightly more favorably. CBM-I outperformed relaxation training on improving perfectionism-relevant interpretation biases (i.e., increasing nonperfectionistic interpretations and decreasing perfectionistic interpretations), though with small effect sizes and inconsistency across study timepoints. Self-reported perfectionism showed small decreases across time in both intervention conditions. Support was found for a key hypothesized mechanism of CBM-I, such that randomization to CBM-I had a longitudinal, indirect effect on decreasing psychopathology symptom scores through improving perfectionism-relevant interpretation biases. However, in light of small effect sizes, the present study failed to provide compelling evidence that CBM-I for perfectionism contributes meaningfully to the treatment of perfectionism.

No pain, no gain? Associations of athletic participation with capability for suicide among college students.

INTRODUCTION: Suicide is a leading cause of death among college students. In order to advance understanding of suicide risk factors in this population, the present study provides a theoretically grounded test of associations between experiences in sports and both facets of capability for suicide (i.e., fearlessness about death and pain tolerance). Secondarily, the present study aimed to explore possible distinctions between subjective and objective pain tolerance. METHODS: Undergraduate students (N = 153) completed the study at a single timepoint. A pressure algometer was used to measure objective pain tolerance, and self-report questionnaires assessed subjective pain tolerance, fearlessness about death (FAD), sports participation, sports-related injuries, level of contact in sport, and weight manipulation practices for sport. RESULTS: Athletes had greater capability for suicide (i.e., higher objective and subjective pain tolerance and greater FAD) relative to non-athletes. Sports-related injuries were positively associated with both FAD and subjective pain tolerance, and level of contact in sport was positively associated with FAD. Objective and subjective pain tolerance were moderately correlated. CONCLUSIONS: Sports-related injuries and level of physical contact in athletics are associated with the facets of capability for suicide among college student athletes. Discrepancies in results between subjective and objective pain tolerance suggest important distinctions between these constructs.

Weight discrimination, anticipated weight stigma, and disordered eating.

Weight discrimination is a well-established risk factor for disordered eating cognitions and behaviors. However, little is known about what may account for this association. Recent research suggests that anticipated weight stigma may explain the relationship between weight discrimination and non-eating disorder related health outcomes; the present study seeks to replicate this premise and extend it to the disordered eating realm. In a non-clinical sample of adults in the United States (N = 297) we test the hypothesis that weight discrimination has an indirect association with eating disorder symptomatology through anticipated stigma. At a single timepoint, participants recruited from the online data collection platform SocialSci completed self-report, online surveys of weight discrimination in day-to-day life, anticipated weight stigma, eating disorder symptoms, and demographic information. As hypothesized, weight discrimination was indirectly associated with greater disordered eating symptoms via its association with anticipated weight stigma. This pattern of results held when controlling for gender, body mass index, and self-perceived weight status. These findings suggest that anticipated stigma is relevant in the association between weight discrimination and greater disordered eating. This premise deserves additional attention using methodological approaches that can facilitate stronger causal claims. We discuss the potential for this line of research to inform clinical interventions.

Interoceptive deficits differentiate suicide groups and associate with self-injurious thoughts and behaviors in a military sample.

OBJECTIVE: Previous research shows that interoceptive deficits are associated with harmful behaviors such as nonsuicidal self-injury (NSSI), eating disorder pathology, and suicide attempts. The present study replicates and extends this area of research by examining the association between interoceptive deficits and suicidality in a military sample. METHOD: In Study 1, respondents to an online survey (N = 134) answered self-report questionnaires related to interoceptive deficits. Study 2 consisted of a secondary data analysis of 3,764 military service members who had previously completed questionnaires on interoceptive indicators, NSSI, suicide thoughts and attempts, and other psychopathology. RESULTS: Study 1 demonstrated that our interoceptive deficits latent variable had adequate psychometric properties. In Study 2, multigroup confirmatory factor analysis showed that scores on the interoceptive deficits latent variable were highest among suicide attempters, lowest among those with no suicide history, and intermediary among participants who had thought about but not attempted suicide. The interoceptive deficits latent variable was more strongly related to NSSI and suicidality than were posttraumatic stress disorder symptoms, hopelessness, gender, and age. CONCLUSIONS: These results confirm-and extend to a military sample-previous research showing that interoceptive deficits can provide important information about suicide risk.

Perfectly imperfect: The use of cognitive bias modification to reduce perfectionism.

BACKGROUND AND OBJECTIVES: Perfectionism is a transdiagnostic risk and maintenance factor for psychopathology. The current study developed and evaluated a cognitive bias modification, interpretation retraining (CBM-I) intervention targeting maladaptive perfectionistic beliefs. METHODS: Participants were undergraduate students randomized to complete the perfectionism CBM-I (n = 33) or control condition task (n = 36) at two time points. Additionally, participants completed measures of perfectionistic interpretations and trait perfectionism, as well as an impossible anagram task designed to elicit perfectionistic concerns. RESULTS: Results indicated that after the intervention, participants who completed the perfectionism CBM-I endorsed fewer perfectionistic interpretations than participants in the control condition. Furthermore, although the study groups self-reported comparably low confidence in their anagram task performance, participants who completed the perfectionism CBM-I reported wanting to re-do significantly fewer anagrams than participants in the control condition, suggesting greater acceptance of imperfect performance following the intervention. Moreover, supporting a key hypothesized mechanism of effect in CBM-I, reductions in perfectionistic interpretations mediated the effect of condition on the desire to re-do anagram task items. LIMITATIONS: The study results should be viewed in light of limitations, including the short time-span of the study, and the use of a relatively small, non-clinical, and demographically homogenous convenience sample. CONCLUSIONS: Further research and development of the perfectionism CBM-I intervention are needed, but the present findings add to a nascent evidence base that suggests CBM-I holds promise as an accessible and transdiagnostic intervention for perfectionism.

Eating disorders and suicidality: what we know, what we don't know, and suggestions for future research.

Suicide is the second leading cause of death among individuals with anorexia nervosa (AN), and suicidal behavior is elevated in bulimia nervosa (BN) and binge eating disorder (BED) relative to the general population. This paper reviews the suicidality literature within each ED, as well as theoretical explanations for the elevated risk for suicidality among those with EDs. Approximately one-quarter to one-third of people with AN, BN, or BED have thought about suicide, and one-quarter to one-third of people with AN and BN have attempted suicide. Relative to gender and aged matched comparison groups, individuals with AN are 18 times more likely to die by suicide, and individuals with BN are seven times more likely to die by suicide. However, the majority of the research in this area is cross-sectional or retrospective, which leaves the timing of the mortality risk unclear. Longitudinal work that is designed to examine dynamic and acute fluctuations in suicidality among ED samples is needed in order to determine meaningful risk factors.

Interoceptive Deficits, Nonsuicidal Self-Injury, and Suicide Attempts Among Women with Eating Disorders.

People with eating disorders (EDs) have an elevated risk for both nonsuicidal self-injury (NSSI) and suicide compared to the general population. This study tests two theoretically derived models examining interoceptive deficits as a risk factor for NSSI, and examining interoceptive deficits, NSSI, fearlessness about death, and pain tolerance as risk factors for suicide. Ninety-six adult, treatment-seeking women with EDs completed self-report questionnaires at a single time point. Interoceptive deficits were significantly associated with NSSI, and NSSI was in turn associated with both pain tolerance and fearlessness about death. Further, pain tolerance was in turn associated with past suicide attempts, although fearlessness about death was not associated with suicide attempts. Interoceptive deficits had a direct association with fearlessness about death but not pain tolerance. Results regarding the relation between interoceptive deficits and suicide attempts were mixed, yet overall suggest that interoceptive deficits are related to suicide attempts largely indirectly, through the effects of mediating variables such as NSSI, fearlessness about death, and pain tolerance. Results suggest that interoceptive deficits and pain tolerance merit further investigation as potential risk factors for fatal and nonfatal self-harm among individuals with EDs.
