Evaluating the Digital Health Experience for Patients in Primary Care: Mixed Methods Study.

BACKGROUND: The digital health divide for socioeconomic disadvantage describes a pattern in which patients considered socioeconomically disadvantaged, who are already marginalized through reduced access to face-to-face health care, are additionally hindered through less access to patient-initiated digital health. A comprehensive understanding of how patients with socioeconomic disadvantage access and experience digital health is essential for improving the digital health divide. Primary care patients, especially those with chronic disease, have experience of the stages of initial help seeking and self-management of their health, which renders them a key demographic for research on patient-initiated digital health access. OBJECTIVE: This study aims to provide comprehensive primary mixed methods data on the patient experience of barriers to digital health access, with a focus on the digital health divide. METHODS: We applied an exploratory mixed methods design to ensure that our survey was primarily shaped by the experiences of our interviewees. First, we qualitatively explored the experience of digital health for 19 patients with socioeconomic disadvantage and chronic disease and second, we quantitatively measured some of these findings by designing and administering a survey to 487 Australian general practice patients from 24 general practices. RESULTS: In our qualitative first phase, the key barriers found to accessing digital health included (1) strong patient preference for human-based health services; (2) low trust in digital health services; (3) high financial costs of necessary tools, maintenance, and repairs; (4) poor publicly available internet access options; (5) reduced capacity to engage due to increased life pressures; and (6) low self-efficacy and confidence in using digital health. In our quantitative second phase, 31% (151/487) of the survey participants were found to have never used a form of digital health, while 10.7% (52/487) were low- to medium-frequency users and 48.5% (236/487) were high-frequency users. High-frequency users were more likely to be interested in digital health and had higher self-efficacy. Low-frequency users were more likely to report difficulty affording the financial costs needed for digital access. CONCLUSIONS: While general digital interest, financial cost, and digital health literacy and empowerment are clear factors in digital health access in a broad primary care population, the digital health divide is also facilitated in part by a stepped series of complex and cumulative barriers. Genuinely improving digital health access for 1 cohort or even 1 person requires a series of multiple different interventions tailored to specific sequential barriers. Within primary care, patient-centered care that continues to recognize the complex individual needs of, and barriers facing, each patient should be part of addressing the digital health divide.

Complications Rates Among Revision Total Knee Arthroplasty Patients Diagnosed With COVID-19 Postoperatively.

BACKGROUND: The COVID-19 pandemic introduced a new set of challenges for the arthroplasty community, including the management of patients diagnosed with COVID-19 following revision total knee arthroplasty (rTKA) and its potential impact on postoperative recovery. This study sought to characterize the risks of postoperative COVID-19 infection among rTKA patients. METHODS: A large national database was utilized to query 8,022 total patients who underwent rTKA between 2018 and 2021, of which 60 had a COVID diagnosis within 90 days after surgery (rTKA/COVID positive). These patients were 1:10 propensity-score matched to 600 rTKA patients who did not have a 90-day postoperative COVID diagnosis (rTKA/COVID negative) and 600 COVID positive patients who did not undergo rTKA. Controlling for potential confounders, multivariate logistic regressions were utilized to compare 90-day postoperative complications between groups. RESULTS: Compared to rTKA/COVID negativepatients, the rTKA/COVID positive cohort had significantly higher rates of pneumonia (odds ratio [OR] = 6.1, P < .001), pulmonary embolism (PE) (OR = 32.4, P < .001), deep venous thrombosis (DVT) (OR = 32.4, P < .001), and 90-day readmissions (OR = 2.1, P = .02). Similarly, the rTKA/COVID positive cohort had significantly higher rates of pneumonia (OR = 4.3, P = .001), PE (OR = 36.8, P < .001), and DVT (OR = 36.8, P < .001) compared to COVID positive patients who did not undergo rTKA. CONCLUSIONS: Revision total knee arthroplasty patients diagnosed with COVID-19 postoperatively had increased rates of thromboembolic events, pneumoniae, and 90-day readmissions. Risk mitigation efforts would suggest extending the prophylactic anticoagulation period for rTKA patients diagnosed with postoperative COVID-19.

Chronic Anticoagulation is Associated With Increased Risk for Postoperative Complications Following Aseptic Revision Total Hip Arthroplasty.

BACKGROUND: With an aging global population, the incidence of revision total hip arthroplasty (rTHA) is expected to increase markedly. While patients undergoing primary total hip arthroplasty who require chronic anticoagulation (AC) have been associated with increased postoperative complications, less is known about the impact of chronic AC status on postoperative complications in the rTHA setting. This study sought to compare complication rates following aseptic rTHA between patients who were on chronic AC and those who were not. METHODS: A large national database was utilized to retrospectively identify 9,421 patients who underwent aseptic rTHA between 2014 and 2019. Patients were divided into 2 cohorts: 1,790 patients (19.0%) were in the chronic AC cohort (ie, having an AC prescription filled within 6 months prior to and following rTHA), and 7,631 patients (81.0%) were not on chronic AC. Postoperative complications at 90-days and 2-years were compared between cohorts utilizing univariate and multivariate analyses, controlling for sex, age, and comorbidities. RESULTS: At 90-days, chronic AC patients had increased odds of prosthetic joint infections (PJIs) (odds ratio [OR] 3.2, P < .001), surgical site infections (OR 3.6, P < .001), and mechanical prosthetic complications (OR 3.5, P < .001), which included any aseptic loosening, implant dislocation, or broken prosthetic. At 2-years, chronic AC patients had increased odds of PJI (OR 3.3, P < .001) as well as mechanical prosthetic complications (OR 3.2, P < .001). Chronic AC patients were also at increased risk for reoperation within 2 years after initial aseptic rTHA (OR 1.9, P < .001). CONCLUSIONS: Patients on chronic AC have significantly higher odds of 90-day and 2-year complications after aseptic rTHA. This includes increased odds of PJI, surgical site infection, and mechanical prosthetic complications. Patients receiving chronic AC who undergo rTHA should be counseled on the risk-benefit ratio of their chronic AC status in a multidisciplinary setting to optimize their postoperative outcomes.

An investigation of the dual continua model of mental health in the context of eating disorder symptomatology using latent profile analysis.

OBJECTIVE: The dual continua model of mental health suggests that mental well-being and mental illness are two distinct continua that are interrelated in their contributions to overall mental health. This study investigated the dual continua model in individuals with eating disorder symptoms. METHOD: Female university students (N = 346) completed measures of mental well-being, eating disorder symptomatology, clinical impairment and psychological distress. Confirmatory factor and latent profile analyses were used to derive underlying mental health profiles. RESULTS: Results revealed two oblique factors representing the mental well-being and eating disorder symptomatology constructs and four unique mental health profiles that were partially consistent with the dual continua model emerged: 'flourishing', 'vulnerable', 'partially symptomatic and content', and 'languishing'. The derived mental health profiles had unique characteristics described by psychological distress and clinical impairment. CONCLUSIONS: The results did not provide conclusive evidence for the dual continua model as they could also be interpreted in a manner consistent with the unidimensional approach. While the dual continua model is a promising avenue to understand mental health in a way that looks beyond symptoms, these results caution against its rapid adoption and encourage future research to understand how eating disorder symptomatology and positive mental health assets contribute to overall mental health.

Measuring social processes regarding eating, physical activity, and weight in higher-weight people: the weight-related interactions scale (WRIS).

PURPOSE: This study sought to develop a psychometrically sound measure to assess effective and ineffective forms of input from others regarding eating, physical activity, and weight in higher-weight people, namely, the Weight-Related Interactions Scale (WRIS). METHODS: Participants (n = 736) were adults in the overweight/obese weight ranges who completed the WRIS and measures of weight-specific social support, emotional eating, weight stigma, eating-specific self efficacy, and social desirability. RESULTS: Exploratory and confirmatory factor analyses of the WRIS supported a three-factor solution of 'Criticism', 'Minimization', and 'Collaboration' as forms of weight-related input from others. Support was found for the reliability and the concurrent, convergent, and divergent validity of the WRIS. CONCLUSIONS: The WRIS is a promising new instrument for comprehensively assessing the input of others in relation to eating, physical activity, and weight among higher-weight individuals. LEVEL OF EVIDENCE: Level III. Evidence obtained from well-designed cohort or case-control analytic studies.

Identifying the contingencies of self-worth associated with eating disorder symptoms: The use of choice-based conjoint analysis.

OBJECTIVE: Self-worth contingent on shape/weight is a diagnostic criterion and key maintaining factor for eating disorders. However, the role of other contingencies of self-worth (i.e., domains in which self-worth is invested) is largely unknown. Moreover, research has relied on self-ratings of contingency strength, which are subject to distortion through socially desirable responding and limited self-awareness, and may have limitations in terms of ecological validity. To overcome these limitations, the present study investigated a broad range of contingencies of self-worth in relation to eating disorder pathology and employed a choice-based conjoint (CBC) approach for assessing these contingencies. METHOD: Young women and men from the community (N = 428) completed a CBC task to assess the domains in which self-worth is invested, the Eating Disorder Examination Questionnaire (EDE-Q) to assess eating disorder symptomatology, and the Balanced Inventory of Desirable Responding to assess socially desirable responding. RESULTS: Beta regression analyses showed that CBC thinness and athletic competence predicted higher scores on all EDE-Q scales. CBC muscularity and facial attractiveness predicted higher scores, while coping ability and quality of relationships predicted lower scores, on various aspects of eating disorder symptoms. CBC social acceptance predicted lower eating disorder symptoms in males only. DISCUSSION: The findings suggest that a broader range of contingencies of self-worth beyond shape/weight are relevant to eating disorder pathology and should be considered as potential underlying mechanisms and treatment targets. In addition, this first use of the CBC method in eating disorder research provides initial support for its validity and utility.

Intentions to see a psychologist for weight management: A cross-sectional study investigating beliefs about psychologists, psychological services and obesity.

OBJECTIVES: The current study investigated beliefs about psychologists, psychological services and obesity, and their association with intentions to see a psychologist for weight management. METHODS: A cross-sectional online survey design was employed in a sample of 136 adults with overweight or obesity (n = 121 females, M age = 37.58, SD = 9.85). RESULTS: Psychologists and psychological services were viewed favourably by participants, with little evidence of role knowledge deficits or significant treatment barriers. Behavioural and social causal beliefs about obesity were indirectly associated with intentions to see a psychologist for weight management through positive associations with psychologists' perceived helpfulness in lifestyle intervention. Indirect effects were not observed for psychological and medical causal beliefs. CONCLUSION: Promotion of psychological services in obesity could highlight their utility in addressing behavioural and social factors. However, there is a need for more research into avoidance of all sources of professional support in this context.

What prevents young adults from seeking help? Barriers toward help-seeking for eating disorder symptomatology.

OBJECTIVES: The aim of this study was to investigate help-seeking attitudes, intentions, and behaviors, and to systematically explore perceived barriers to help-seeking for eating, weight, or shape concerns among young adults. Differences in perceived barriers as a function of type of eating disorder symptomatology were also examined. METHOD: Data were collected using an online survey among individuals (aged 18-25 years) in Australia. Overall, 291 young adults with varying levels of eating disorder symptoms completed measures of disordered eating, weight or shape concerns, help-seeking barriers, attitudes, intentions, and behaviors. According to their self-reported symptoms, participants were classified into four subgroups (i.e., anorexia nervosa [AN] symptoms, bulimia nervosa [BN] symptoms, binge-eating disorder [BED] symptoms, and other eating disorder symptoms). RESULTS: Despite the belief that help-seeking is useful, only a minority of participants with elevated symptoms, namely those with AN, BN, and BED symptoms, believed they needed help. Across the sample, the most frequently cited barriers to seeking help for eating disorder symptoms were: concern for others, self-sufficiency, fear of losing control, denial and failure to perceive the severity of the illness, and stigma and shame. DISCUSSION: The findings highlight the need to educate young adults about the severity of eating disorders and the importance of seeking help, and to increase the awareness of help-seeking barriers among those designing public health interventions as well as clinicians. Our findings suggest that help-seeking barriers may differ depending on the type of eating disorder symptomology.

The effectiveness of touchscreen-based attentional bias modification to thin body stimuli on state rumination.

Ruminative thinking is considered a vulnerability factor for eating disorder symptomatology. Research suggests that attentional bias to body shape stimuli may serve to underpin this maladaptive form of emotion regulation. The current study aimed to determine the direct effect of attentional bias to thin-ideal bodies on state depressive rumination. Additionally, this study sought to evaluate the efficacy of attentional bias modification (ABM) utilising a touchscreen device. A well-established ABM protocol, the modified dot probe task, was used for both attentional assessment and training. Female undergraduate students (N = 110) completed an ABM session where attention was trained either towards, or away from, thin-ideal body images. Pre- and post-attentional training, participants completed the dot probe task, as well as a state measure of depressive rumination. Results revealed that the ABM training induced a greater attentional bias to thin-ideal bodies in the attend-thin training condition than in the avoid-thin training condition. Furthermore, induced attentional avoidance of thin-ideal bodies led to a significant reduction in state depressive rumination. The current findings suggest that touchscreen-based ABM is effective in modifying patterns of attentional bias and state depressive rumination.

Reducing anorexia nervosa stigma: an exploration of a social consensus intervention and the moderating effect of blameworthy attributions.

Background: Research suggests that blameworthy attributions towards individuals with anorexia nervosa are common, which in turn elicit more stigmatising attitudes towards those with the disorder. The social consensus approach has been found to reduce stigmatising attitudes in various domains and, as such, is a promising avenue to pursue for ameliorating stigma in anorexia nervosa.Aims: The present study primarily sought to investigate the effectiveness of a social consensus approach in reducing stigma towards individuals with anorexia nervosa. The study also examined if blameworthy attributions were associated with change in stigma.Method: An experimental design was employed, where female undergraduate students (N= 126) completed self-report measures that assessed anorexia nervosa stigma at baseline (Time 1) and 6-10 days after allocation to one of two conditions: social consensus and control (Time 2).Results: The social consensus intervention was more effective than the control condition in reducing stigmatising attitudes on measures assessing affective reactions (p= 0.025) and characteristics attributed to a target with anorexia nervosa (p < 0.001). Level of blame-based attributions did not moderate change in stigma.Conclusions: Results suggest that a social consensus intervention is promising irrespective of the endorsement of blameworthy attributions.

Adaption and validation of the Working Alliance Inventory for General Practice: qualitative review and cross-sectional surveys.

BACKGROUND: Relational aspects of primary care are important, but we have no standard measure for assessment. The 'working alliance' incorporates elements of the therapeutic relationship, shared decision-making, goal setting and communication skills. The Working Alliance Inventory (short form) (WAI-SF) has been used in adult psychology, and a high score on the survey is associated with improved outcomes for clients. OBJECTIVE: To adapt the WAI-SF for use between GPs and patients and to test its concurrent validity with measures of shared decision-making and the doctor-patient relationship and discriminant validity with measures of social desirability. METHODS: Two rounds of online survey feedback from 55 GPs and 47 patients were used to adapt the WAI-SF-the WAI-GP. The tool was then completed by 142 patients in waiting rooms after seeing their GP and by 16 GPs at the end of their session. Concurrent validity with measures of shared decision-making and patient-doctor depth of relationship was determined using Spearman Rho correlations. Patients also completed two social desirability surveys, and discriminant validity with WAI-GP was assessed. RESULTS: Following feedback, the survey was re-worded to remove phrases that were perceived as judgmental or irrelevant. The patient measure of the WAI-GP was strongly correlated with Dyadic OPTION (rho = 0.705, P = 0.0001) and Patient-Doctor Depth of Relationship scale (rho = 0.591, P = 0.0001) and not with measures of social desirability. CONCLUSION: The psychometric properties of the WAI-GP support its use for measuring GP-patient alliance. Possibilities for use include assessing the influence of therapeutic alliance on the effectiveness of interventions.

How eating disordered and non-eating disordered women differ in their use (and effectiveness) of cognitive self-regulation strategies for managing negative experiences.

PURPOSE: The present study compared the use (and effectiveness) of cognitive self-regulation strategies in eating disordered (ED) and non-eating disordered women (non-ED), and whether ED subgroups differ in their use of avoidant/suppressive strategies and cognitive reappraisal. METHODS: The participants consisted of 90 adult patients recruited from a specialist eating disorder service and 97 adults without an ED. Cognitive self-regulation strategies were examined on a baseline self-report measure and while looking in a mirror. RESULTS: The results of this study showed that, relative to the non-ED group, ED participants engage in more worry and self-punishment and less distraction and social control strategies in general but not specifically during a body exposure task. Reappraisal strategies were equally likely to be used by clinical and non-clinical groups but participants with anorexia nervosa (AN) found them less effective during the task. Non-ED participants found distraction strategies more effective than the ED group for managing the body exposure experience. ED subgroups used avoidant/suppressive strategies and cognitive reappraisal strategies to a similar extent. CONCLUSION: The use of maladaptive self-regulation strategies, and the use and effectiveness of some of the more adaptive self-regulation strategies sets eating disorders apart from those without an eating disorder, supporting previous research in the area. Contrary to what was predicted, the results were similar across ED subgroups. The findings highlight the importance of cognitive self-regulation strategies as a focus of research and clinical intervention. LEVEL OF EVIDENCE: Level III: Case-control study.

Vulnerable narcissism as a mediator of the relationship between perceived parental invalidation and eating disorder pathology.

PURPOSE: Parental invalidation and narcissism have been proposed to play an important role in understanding the etiology of eating disorders. The current research aimed to address two main gaps in the literature. The first aim was to determine the differential associations of grandiose and vulnerable narcissism with eating disorder pathology. The second aim was to find a common mediator between both maternal and paternal invalidation and eating disorder pathology. It was hypothesized that when controlling for vulnerable narcissism, grandiose narcissism would not predict eating disorder pathology. In addition, it was hypothesized that vulnerable narcissism would be a mediator of the relationship between parental invalidation and eating disorder pathology. METHODS: Participants were 352 women aged 18-30 years who were recruited from the general and tertiary student population, and as such constituted a community sample. Participants completed the Invalidating Childhood Environment Scale, Brief-Pathological Narcissism Inventory, Eating Disorder Examination Questionnaire, the Avoidance of Affect Subscale of the Distress Tolerance Scale, and the Emotional Expression as a Sign of Weakness Subscale of the Attitudes Towards Emotional Expression Scale in an online survey. RESULTS: Results showed that, when controlling for vulnerable narcissism, grandiose narcissism was no longer associated with eating disorder pathology. It was also found that parental invalidation had a positive indirect effect upon eating disorder pathology, via vulnerable narcissism. CONCLUSIONS: The findings indicate that vulnerable narcissism is more strongly associated with eating disorder pathology as opposed to grandiose narcissism and help to further elucidate the mechanisms via which parental invalidation might exert its negative effect on eating disorder pathology. LEVEL OF EVIDENCE: A cross-sectional survey (Level V).

Evidence for a perceptual mechanism relating body size misperception and eating disorder symptoms.

PURPOSE: There are known and serious health risks associated with extreme body weights, including the development of eating disorders. Body size misperceptions are particularly evident in individuals with eating disorders, compared to healthy controls. The present research investigated whether serial dependence, a recently discovered bias in body size judgement, is associated with eating disorder symptomatology. We additionally examined whether this bias operates on holistic body representations or whether it works by distorting specific visual features. METHODS: A correlational analysis was used to examine the association between serial dependence and eating disorder symptomatology. We used a within-subjects experimental design to investigate the holistic nature of this misperception. Participants were 63 young women, who judged the size of upright and inverted female body images using a visual analogue scale and then completed the Eating Disorder Examination-Questionnaire (EDE-Q) to assess eating disorder symptoms. RESULTS: Our findings provide the first evidence of an association between serial dependence and eating disorder symptoms, with significant and positive correlations between body size misperception owing to serial dependence and EDE-Q scores, when controlling for Body Mass Index. Furthermore, we reveal that serial dependence is consistent with distortion of local visual features. CONCLUSIONS: Findings are discussed in relation to the broader theories of central coherence, cognitive inflexibility, and multisensory integration difficulties, and as providing a candidate mechanism for body size misperception in an eating disorder population. LEVEL OF EVIDENCE: Level 1, experimental study.

Reducing the stigma associated with anorexia nervosa: An evaluation of a social consensus intervention among Australian and Chinese young women.

OBJECTIVE: This study examined the effectiveness of a social consensus intervention in reducing stigma toward individuals with anorexia nervosa (AN) among women from Australia and mainland China. Moreover, the different predictions of informational/normative social influence theory and the social identity approach in terms of the effectiveness of the social consensus intervention were investigated. METHOD: Participants were female students from the Australian National University (n = 97) and Central China Normal University (n = 76) who reported their levels of stigma toward a fictional character with AN before and after receiving normative information regarding the attitudes of others toward people with AN. Three experimental conditions of normative information were utilized: in-group, out-group, and neutral. RESULTS: Chinese participants reported higher levels of baseline stigma across all measures than Australian participants. Social consensus was effective in reducing most types of AN stigma, and supported the social identity approach in that improvements in attitudinal, affective, and behavioral aspects of stigma were significantly greater for participants in the in-group (but not the out-group) versus the neutral condition. The effectiveness of the social consensus approach was not moderated by nationality. DISCUSSION: A social consensus approach holds potential as an additional strategy for reducing AN stigma, with its benefits extending across diverse cultural settings. Such an approach would entail ensuring that positive messages regarding people with AN are delivered by members of a valued in-group.

Indicators of clinical significance among women in the community with binge-eating disorder symptoms: Delineating the roles of binge frequency, body mass index, and overvaluation.

OBJECTIVE: This study aimed to investigate the relative contributions of binge eating, body image disturbance, and body mass index (BMI) to distress and disability in binge-eating disorder (BED). METHOD: A community sample of 174 women with BED-type symptomatology provided demographic, weight, and height information, and completed measures of overvaluation of weight/shape and binge eating, general psychological distress and impairment in role functioning. Correlation and regression analyses examined the associations between predictors (binge eating, overvaluation, BMI), and outcomes (distress, functional impairment). RESULTS: Binge eating and overvaluation were moderately to strongly correlated with distress and functional impairment, whereas BMI was not correlated with distress and only weakly correlated with functional impairment. Regression analysis indicated that both overvaluation and binge eating were strong and unique predictors of both distress and impairment, the contribution of overvaluation to variance in functional impairment being particularly strong, whereas BMI did not uniquely predict functional impairment or distress. DISCUSSION: The findings support the inclusion of overvaluation as a diagnostic criterion or specifier in BED and the need to focus on body image disturbance in treatment and public health efforts in order to reduce the individual and community health burden of this condition.

Body image predictors of depressive symptoms in adolescence.

INTRODUCTION: Depression rises significantly in adolescence, with females reporting twice the prevalence of males into adulthood. In accordance with cognitive vulnerability theories, eating and weight-related disturbances have been implicated in this increase, but a broader assessment of body image constructs within this framework is needed. METHODS: The current prospective study examined body importance, body dissatisfaction, and body change strategies to lose weight and increase muscularity as predictors of depressive symptoms over one year in N = 298 adolescents in Canberra, Australia (at Time 2, the sample comprised n = 161 female adolescents, Mage = 15.36 years, SD = 1.10; n = 137 male adolescents, Mage = 15.54 years, SD = 1.15). The moderating role of sex was also assessed. RESULTS & CONCLUSIONS: Results revealed that body importance and body change strategies to increase muscularity explained significant variance in depressive symptoms beyond baseline covariates of depressive symptoms and stress, with the effect of body importance relevant in female but not male adolescents. The findings support the use of more comprehensive assessments of body image constructs to inform cognitive vulnerability theories of adolescent depression, and corresponding prevention and intervention programs.

Persistent body image disturbance following recovery from eating disorders.

OBJECTIVE: Individuals with an eating disorder experience the rubber hand illusion (RHI) significantly more strongly than healthy controls on both perceptual (proprioceptive drift) and subjective (self-report embodiment questionnaire) measures. This heightened sensitivity to visual information about the body, and/or reduced somatosensory information processing about the body, suggest an increased malleability of the bodily self. The aim of the present study was to explore whether this is a state phenomenon or a persisting individual trait that outlasts the period of acute eating disorder. METHOD: The RHI and self-report measures of eating disorder psychopathology (EDI-3 subscales of Drive for Thinness, Bulimia, Body Dissatisfaction, Interoceptive Deficits, and Emotional Dysregulation; DASS-21; and the Self-Objectification Questionnaire) were administered to 78 individuals with an eating disorder, 28 individuals recovered from an eating disorder, and 61 healthy controls. RESULTS: Proprioceptive drift in recovered individuals was intermediate between the acutely ill and HC groups. Subjective report of the strength of the illusion in recovered individuals was similar to acutely ill individuals. DISCUSSION: These results suggest that increased malleability of the bodily self persists, at least partially, following recovery and may be a trait phenomenon in people with eating disorders. Those with a lifetime history of an eating disorder may have heightened sensitivity to visual information about the body and reduced somatosensory information processing of the body.

Internet-based motivation program for women with eating disorders: eating disorder pathology and depressive mood predict dropout.

BACKGROUND: One of the main problems of Internet-delivered interventions for a range of disorders is the high dropout rate, yet little is known about the factors associated with this. We recently developed and tested a Web-based 6-session program to enhance motivation to change for women with anorexia nervosa, bulimia nervosa, or related subthreshold eating pathology. OBJECTIVE: The aim of the present study was to identify predictors of dropout from this Web program. METHODS: A total of 179 women took part in the study. We used survival analyses (Cox regression) to investigate the predictive effect of eating disorder pathology (assessed by the Eating Disorders Examination-Questionnaire; EDE-Q), depressive mood (Hopkins Symptom Checklist), motivation to change (University of Rhode Island Change Assessment Scale; URICA), and participants' age at dropout. To identify predictors, we used the least absolute shrinkage and selection operator (LASSO) method. RESULTS: The dropout rate was 50.8% (91/179) and was equally distributed across the 6 treatment sessions. The LASSO analysis revealed that higher scores on the Shape Concerns subscale of the EDE-Q, a higher frequency of binge eating episodes and vomiting, as well as higher depression scores significantly increased the probability of dropout. However, we did not find any effect of the URICA or age on dropout. CONCLUSIONS: Women with more severe eating disorder pathology and depressive mood had a higher likelihood of dropping out from a Web-based motivational enhancement program. Interventions such as ours need to address the specific needs of women with more severe eating disorder pathology and depressive mood and offer them additional support to prevent them from prematurely discontinuing treatment.

An investigation of interoceptive sensitivity in eating disorders using a heartbeat detection task and a self-report measure.

BACKGROUND: Interoception has been proposed to play an important role in the pathogenesis of eating disorders (EDs). OBJECTIVE: The aim of this study was to examine a heart beat detection task (HBDT) as an objective index of interoceptive sensitivity in individuals with an ED. METHOD: The self-report interoceptive deficits subscale of the Eating Disorders Inventory 3 was also used. RESULTS: The results of the HBDT demonstrated no significant difference between individuals with an ED and healthy controls. However, performance on this task also did not appear to be different from that expected by chance. Thus, these results cast doubt on the utility of the present HBDT for measuring interoceptive sensitivity. CONCLUSION: Overall, the findings indicate that further research is needed to develop valid, objective measures of interoceptive sensitivity to be used in EDs, so as to overcome the reliance on the Eating Disorders Inventory 3 self-report subscale and to determine how such measures relate to ED and general psychopathology.
