RÉSUMÉ

(1) Background: The integrated approach to the prevention and treatment of eating disorders (EDs) requires knowledge and can be used only when specific risk factors are known. The aim of this study was to examine the differences in food choices and eating behavior between males and females; (2) Methods: This study comprised 148 females and 27 males aged from 18 to 26-years-old (MEAN ± SD = 21.4 ± 1.86 years old). Information about EDs was obtained from four different measures: the body mass index (BMI), the eating disorder screen for primary care (ESP), a standardized and validated questionnaire called "My Eating Habits" and the food frequency questionnaire with 10 answers (FFQ-10); (3) Results: The risk for developing eating disorders was detected in nearly 67% of respondents. It was also shown that EDs were more common in females and how body weight affected the way individuals feel about themselves. Females showed more unhealthy eating habits, which contributed to dietary restrictions and emotional overeating, as they were also afraid of gaining weight. The frequency of eating meat and drinking alcohol was higher in males, whereas eating legume seeds was less frequent in females. (4) Conclusions: This study opens a new field, which will help health care professionals recognize the problems with eating disorders and treat them based on different sex characteristics.

RÉSUMÉ

PURPOSE OF REVIEW: This review explores potential sources of weight bias and stigma during the COVID-19 pandemic, including "quarantine-15" messages and discussion of obesity in media and public health campaigns. We examine evidence of the effects of weight bias on well-being during the pandemic and highlight unanswered questions to be addressed in future research. RECENT FINDINGS: Studies that have investigated weight change during stay-at-home orders have yielded mixed findings and relied predominantly on self-reported retrospective recall, thus providing weak evidence of a widespread "quarantine-15" effect. No studies to date have evaluated the effects on weight stigma and health of obesity-focused COVID-19 media and public health messages. Individuals with a history of experiencing weight bias may be more vulnerable to binge eating and psychological distress during the pandemic. Weight bias and stigma during the COVID-19 pandemic, and their effects on health and well-being, warrant greater investigation and consideration in public health efforts.

RÉSUMÉ

OBJECTIVES: This project examined risk factors of disordered eating in athletes by adapting and applying a theoretical model. It tested a previously proposed theoretical model and explored the utility of a newly formed model within an athletic population across gender, age, and sport type to explain disordered eating. DESIGN: The design was cross-sectional and the first phase in a series of longitudinal studies. METHODS: 1,017 athletes completed online questionnaires related to social pressures, internalisation, body dissatisfaction, negative affect, restriction, and bulimia. Structural equation modelling was employed to analyse the fit of the measurement and structural models and to do invariance testing. RESULTS: The original theoretical model failed to achieve acceptable goodness of fit (χ2 [70, 1017] = 1043.07; p < .0001. CFI = .55; GFI = .88; NFI = .53; RMSEA = .12 [90% CI = .111-.123]). Removal of non-significant pathways and addition of social media resulted in the model achieving a parsimonious goodness of fit (χ2 [19, 1017] = 77.58; p < .0001. CFI = .96; GFI = .98; NFI = .95; RMSEA = .055 [90% CI = .043-.068]). Invariance tests revealed that the newly revised model differed across gender, age, level, competition status, and length of sport participation. CONCLUSION: This study showed that the formation of disordered eating symptomology might not be associated with sport pressures experienced by athletes. It revealed that disordered eating development varies across gender, competition level, sport type, and age, which must be considered to prevent and treat disordered eating in athletes.

RÉSUMÉ

The purpose of the study was to investigate the relationship between mindful eating, disordered eating and mood in university students in health-related disciplines. A total of 221 university students participated in the study; 102 students studied sport and exercise science (SS), 54 students pharmacy sciences (PS), and 65 students health sciences (HS). Participants completed the Binge Eating Scale (BES), the Mindful Eating Questionnaire (MEQ), and the Profile of Mood State questionnaire (POMS). 41% of the students were classified as binge eaters and 57% were above the POMS threshold of depression. Binge eaters were found to have significantly lower MEQ score and significantly higher total mood disturbance scores (TMD) compared to non-binge eaters (p < 0.01). Students with a high depression score exhibited no differences in the MEQ score but a significantly higher BES score compared to non-depressed students (p < 0.01). Gender differences were found in the MEQ with females exhibiting significantly higher scores in the MEQ score and in all MEQ subscales compared to males, with the exception of the emotional subscale that females were noted to have a lower score compared to males (p < 0.01). The MEQ score was inversely related to the BES score (r = -0.30, p < 0.01) and TMD (r = -0.21, p < 0.05). The MEQ score was a significant negative predictor of the variance of the binge eating behavior of the students (B = -3.17, p < 0.001). In conclusion, mindfulness in eating is inversely related to the binge eating behavior and mood state of university students studying health-related subjects and is a significant negative predictor of disordered eating behavior in this high risk population.

RÉSUMÉ

Overeating is a major contributing factor to obesity and related health complications. For women, in particular, negative emotions such as stress strongly influence eating behavior and bingeing episodes. Modeling this type of binge eating in rodents presents challenges: firstly, stress-induced anorexia is commonly observed in rodents therefore a mild stressor is required in order to observe an orexigenic effect. Second, many studies report using calorie restriction to observe the required behavior; yet this does not necessarily reflect the human condition. Thus, the aim of this study was to develop a model of emotional stress-induced bingeing independent of caloric restriction. Female and male C57BL/6J mice were divided into ad libitum (n = 20 per sex) and food-restricted (n = 20 per sex) groups which were both further split into a control group and a group exposed to frustration stress (n = 10 per group). All mice were provided intermittent access to a highly palatable food in 2 cycles. At the end of each cycle the stress group was subjected to a 15-minute frustration episode where highly palatable food was within the home cage but inaccessible. Both groups were then given free access for 15 minutes. Frustrated female mice from the ad libitum displayed binge-like behavior compared with controls (P = .0001). Notably, this behavior was absent in males. Ovariectomy had no impact on binge-like behavior. Collectively, these data validate a novel model of emotional stress-induced binge eating specific to female mice which does not require caloric restriction and is not driven by ovarian hormones.

RÉSUMÉ

BACKGROUND: Although bariatric surgery is an effective intervention for severe obesity, a subset of patients demonstrates suboptimal weight outcomes. Postoperative loss of control eating (LOCE) and binge eating may influence weight outcomes, though research has not examined differences by surgical procedure, or factors that predict postoperative LOCE. This study aimed to [1] characterize LOCE and binge eating disorder (BED) over a 7-year period following bariatric surgery; [2] examine concurrent, prospective, and cumulative relationships between LOCE and weight loss; [3] assess whether these associations are moderated by surgery type; and [4] evaluate predictors of LOCE. METHODS: Participants were 2156 patients who underwent laparoscopic adjustable gastric banding (LAGB) or Roux-n-Y gastric bypass (RYGB) in the multi-center Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study. Generalized linear mixed models examined relationships between LOCE and percent weight loss and predictors of LOCE. RESULTS: LOCE and BED initially declined then increased after surgery, with a notable number of de-novo cases (25.6% and 4.8%, respectively). LOCE was related to less concurrent but not prospective or cumulative percent weight loss. Self-monitoring of eating, higher daily eating frequency, older age, male gender, and higher self-esteem were associated with a lower likelihood of LOCE. CONCLUSIONS: Results suggest that LOCE and binge eating are clinically relevant behaviors that may impede weight loss, and findings highlight the importance of ongoing assessment of maladaptive eating following surgery.

RÉSUMÉ

OBJECTIVE: Dental treatment and orofacial surgeries may induce chronic neuropathic orofacial pain (CNOP). This kind of pain affects adaptability to environmental changes in both model animals and humans. Part of the adaptation process depends on the ability to distinguish between familiar and novel stimuli. CNOP induces novelty seeking behaviour as a deficit in environmental adaptation. Alternatively, novelty seeking is a sign for susceptibility to the development of substance abuse. Evidence shows that CNOP leads to alcoholism in animal models. The behavioural relationship between CNOP, novelty seeking behaviour and substance abuse is unknown. In this article, we investigate if CNOP produces an increase in novelty seeking and leads to increasing ethanol intake. DESIGN: Firstly, we used mental nerve injury as a neuropathic orofacial pain model to evaluate both thermal and mechanical allodynia. We used the novel recognition task to determine novelty seeking behaviour and the drink in darkness protocol to assess ethanol intake. RESULTS: Our results show that mental nerve constriction increases novelty seeking behaviour (p = 0.01) and correlates with ethanol binge consumption (r2 = 0.68, p = 0.0008). CONCLUSIONS: The present study demonstrates, for the first time, that trigeminal nerve injury, which induces CNOP, is enough to provide novelty seeking behaviour and lead to increasing ethanol intake. The increase of novelty seeking behaviour can serve as a predictor of risk of developing substance abuse. The treatment of CNOP involves a high risk of producing addiction. The level of novelty seeking evaluation in patients with neuropathic pain before treatment is critical.

RÉSUMÉ

BACKGROUND: As the number of surgeries increases and the elapsed time of the realization increases as well, the postoperative evaluations would become increasingly necessary. AIM: To assess the psychological profile before and after surgery. METHODS: Were evaluated 281 patients from the public service of bariatric surgery. In this study, 109 patients completed the evaluations before surgery (T0) and up to 23 months after surgery (T1); 128 completed the evaluations in T0 and between 24 months and 59 months after surgery (T2); and 44 completed the evaluations in T0 and 60 months after surgery (T3). A semi-structured interview, the Beck Depression Inventory (BDI), Beck Anxiety (BAI), and the Binge Eating Scale (BES) were used. RESULTS: There was a higher prevalence of female (83%), patients with less than 12 years of education (83%), and patients who have a partner (64%). Analyzing all times of evaluation, regarding anxiety, depression, and binge eating, there was a reduction in all symptoms in T1, pointing to significant improvements in the first 23 months after surgery. Already, in T2 and T3, there was an increase in all indicators of anxiety, depression, and binge eating pointing to the transient impact of weight loss or bariatric surgery on these symptoms. CONCLUSIONS: This study shows the importance of the continuous psychological evaluation and needs for the appropriate interventions for these patients who have undergone bariatric surgery, even after weight loss.

RÉSUMÉ

BACKGROUND: Patients experiencing insufficient weight loss or weight regain in their first bariatric surgery may represent a high-risk group with greater problematic eating and general psychopathology levels, which may compromise the success of a reoperative procedure. OBJECTIVES: This study seeks to describe and compare disordered eating-related psychological and behavioral features of primary and reoperative surgery candidates after gastric band. SETTING: Hospital center and university in Portugal. METHODS: The baseline (preoperative) data from a longitudinal observational study are presented. Patients were interviewed by trained psychologists to identify binge-eating episodes and grazing and responded to a set of self-report measures: disordered eating, grazing, negative urgency, depression, anxiety, and stress. RESULTS: Two hundred twenty-five patients were undergoing primary surgery, and 166 were undergoing reoperative (REOP group) surgery. The groups did not differ in body mass index preoperatively, but the REOP group had greater weight suppression (t387 = -5.35, P = .001), higher highest (t387 = -3.40, P = .001) and lower lowest body mass index (t381 = 2.22, P = .03). The main reasons for reoperative surgery were weight regain/poor weight loss (42.8%) or medical complications (32.5%). REOP patients with objective binge eating reported a higher frequency of these episodes (t47 = 2.15, P = .04). No significant difference was found for the self-report measures assessed (only shape concern was higher for REOP group, F1,216 = 8.30, P<.001). CONCLUSIONS: Despite the preoperative similarities between patients undergoing reoperative or primary surgeries, the differences in binge eating and weight-related variables may associate with postoperative difficulties. The link between binge eating, weight suppression, and weight gain found in other samples suggests that patients undergoing reoperative surgery may be at increased risk for poor weight outcomes.

RÉSUMÉ

Studies indicate that Polycystic Ovarian Syndrome (PCOS) features (e.g. insulin instability, food cravings, overproduction of androgens and menstrual irregularities) are associated with increased appetite, impaired impulse control and feelings of body dissatisfaction. Counter intuitively, binge eating behaviors have been shown to reinforce PCOS symptomatology, precipitating concurrently body dissatisfaction, weight gain, insulin instability and overproduction of androgens. The present systematic literature review aspires to investigate the relationship between binge eating, in the broader context of eating disorder behaviors, and Polycystic Ovarian Syndrome (PCOS), taking into account shared characteristics between EDs (Eating Disorders) and PCOS. To address this aim, the PRISMA guidelines are adopted. A total of 21 studies, which investigated the presence of binge eating in PCOS population and the presence of PCOS in EDs population, were synthesized. Findings suggested that an increased prevalence of binge eating has been reported in women with Polycystic Ovarian Syndrome (PCOS); and that women suffering from BN (Bulimia Nervosa) and BED (Binge Eating Disorder) are more likely to display polycystic ovaries. Further research on their shared liability is required in order to inform more efficient prevention and treatment initiatives for populations presenting with comorbid features.

RÉSUMÉ

Type 1 diabetes mellitus (T1DM) is a common chronic disease in children and young people. Living with diabetes can pose many challenges both medical and psychological. Disordered eating behaviours, intentional insulin omission and recognised eating disorders are common among young people with diabetes and are associated with increased risk of short-term and long-term complications and death. Recognition of these behaviours is important to ensure that relevant support is provided. Joint working between diabetes and mental health teams has challenges but is essential to ensure all needs are met during treatment and recovery.

RÉSUMÉ

Objectives: This study tested hypotheses drawn from a risk model positing that psychosocial risk plus disease-related and treatment factors contribute to bulimic symptoms in youth with type 1 diabetes (T1D) transitioning to an insulin pump. The goal of this study was to examine whether disease-related factors, particularly disease- and treatment-based disruption in hunger and satiety, contribute to report of bulimic symptoms in youth with T1D after accounting for psychosocial risk factors. Methods: 43 youth (ages 10-17, 54% female) with established T1D were recruited before transition from multiple daily injections to insulin-pump therapy from three tertiary pediatric diabetes centers. Participants completed measures of bulimic symptoms, depressive symptoms dietary restraint, and the Diabetes Treatment and Satiety Scale, a diabetes-specific questionnaire assessing hunger and satiety cues and eating behavior in response to blood glucose levels and treatment. Results: Hierarchical multiple regression was used to assess contributions of psychosocial and disease-based risk to report of bulimic symptoms. After assessing the contributions of body mass index, body image dissatisfaction, and dietary restraint, a significant 2-way interaction emerged between depression and diabetes-related uncontrollable hunger related to bulimic symptoms (ß = 1.82, p < .01). Conclusions: In addition to psychosocial risk, disease- and treatment-based hunger and satiety dysregulation appear to be important factors contributing to report of bulimic symptoms in youth with T1D. These preliminary findings have significant treatment implications for bulimic symptoms in youth with T1D.

RESUMO Racional: Avaliações pós-operatórias têm se tornado necessárias em ciruriga bariátrica considerando o grande número de operações e o tempo decorrido de sua realização. Objetivo: Avaliar o perfil psicológico de pacientes de um serviço público de cirurgia bariátrica antes e após o procedimento. Métodos: Foram avaliados no total 281 pacientes. Destes, 109 completaram as avaliações antes (T0) e até 23 meses após a operação (T1); 128 completaram as avaliações em T0 e entre 24 meses e 59 meses após a operação (T2); e 44 completaram as avaliações em T0 e 60 meses após a operação (T3). Foram utilizados entrevista semi-estruturada, Inventário Beck de Depressão (BDI), Inventário Beck de Ansiedade (BAI) e Escala de Compulsção Alimentar Periódica (ECAP). Resultados: Observou-se maior prevalência de mulheres (83%), pacientes com menos de 12 anos de escolaridade (83%) e pacientes que tinham um companheiro(a) (64%). Ao analisar todos os tempos de avaliação, observou-se que, com relação à ansiedade, depressão e compulsão alimentar, houve redução de todos os sintomas em T1, apontando para melhorias significativas nos primeiros 23 meses após a operação. Já em T2 e T3 observou-se aumento de todos os indicadores de ansiedade, depressão e compulsão alimentar, apontando para o impacto transitório da perda de peso alcançada pela cirurgia bariátrica nesses sintomas. Conclusões: Este estudo mostra a importância de avaliações psicológicas contínuas e a necessidade de intervenções multiprofissionais apropriadas para pacientes submetidos à cirurgia bariátrica, mesmo após a perda de peso.

RÉSUMÉ

Background: Observational studies have shown that higher body mass index (BMI) is associated with increased risk of developing disordered eating patterns. However, the causal direction of this relation remains ambiguous.Objective: We used Mendelian randomization (MR) to infer the direction of causality between BMI and disordered eating in childhood, adolescence, and adulthood.Design: MR analyses were conducted with a genetic score as an instrumental variable for BMI to assess the causal effect of BMI at age 7 y on disordered eating patterns at age 13 y with the use of data from the Avon Longitudinal Study of Parents and Children (ALSPAC) (n = 4473). To examine causality in the reverse direction, MR analyses were used to estimate the effect of the same disordered eating patterns at age 13 y on BMI at age 17 y via a split-sample approach in the ALSPAC. We also investigated the causal direction of the association between BMI and eating disorders (EDs) in adults via a two-sample MR approach and publically available genome-wide association study data.Results: MR results indicated that higher BMI at age 7 y likely causes higher levels of binge eating and overeating, weight and shape concerns, and weight-control behavior patterns in both males and females and food restriction in males at age 13 y. Furthermore, results suggested that higher levels of binge eating and overeating in males at age 13 y likely cause higher BMI at age 17 y. We showed no evidence of causality between BMI and EDs in adulthood in either direction.Conclusions: This study provides evidence to suggest a causal effect of higher BMI in childhood and increased risk of disordered eating at age 13 y. Furthermore, higher levels of binge eating and overeating may cause higher BMI in later life. These results encourage an exploration of the ways to break the causal chain between these complex phenotypes, which could inform and prevent disordered eating problems in adolescence.

RÉSUMÉ

Twin studies show the established relation between bulimic symptoms and problematic alcohol involvement in adult females is partly due to shared familial factors, specifically shared genetic effects. However, it is unclear if similar shared etiological factors exist during adolescence or in males. We examined the familial overlap (i.e., genetic and common environmental correlations) between bulimic symptoms and various levels of alcohol involvement in 16- to 17-year-old female and male same-sex twin pairs using sex-specific biometrical twin modeling. Bulimic symptoms were assessed with the Eating Disorder Inventory-2. Alcohol involvement included alcohol use in the last month, having ever been intoxicated, and alcohol intoxication frequency. Results revealed 3 distinct patterns. First, in general, phenotypic correlations indicated statistically similar associations between bulimic symptoms and alcohol involvement in girls and boys. Second, common environmental overlap was significant for the bivariate associations including having ever been intoxicated. Third, moderate genetic correlations were observed between all bulimic symptoms and alcohol involvement in girls and moderate common environmental correlations were observed in boys for the more risky/deviant levels of involvement. Similar to adults, there is familial overlap between bulimic symptoms and alcohol involvement in adolescent girls and boys. These results could inform symptom- and sex-specific, developmentally targeted prevention and intervention programs for the comorbidity between bulimic symptoms and alcohol involvement.

RÉSUMÉ

BACKGROUND: Prior research demonstrated that attention-deficit hyperactivity disorder (ADHD) is associated with binge-eating behavior, binge-eating disorder (BED), and bulimia nervosa (BN). The aim of this study was to investigate these associations in an adult twin population, and to determine the extent to which ADHD symptoms and binge-eating behavior share genetic and environmental factors. METHODS: We used self-reports of current ADHD symptoms and lifetime binge-eating behavior and associated characteristics from a sample of over 18 000 adult twins aged 20-46 years, from the population-based Swedish Twin Registry. Mixed-effects logistic regression was used to examine the association between ADHD and lifetime binge-eating behavior, BED, and BN. Structural equation modeling was used in 13 773 female twins to determine the relative contribution of genetic and environmental factors to the association between ADHD symptoms and binge-eating behavior in female adult twins. RESULTS: ADHD symptoms were significantly associated with lifetime binge-eating behavior, BED, and BN. The heritability estimate for current ADHD symptoms was 0.42 [95% confidence interval (CI) 0.41-0.44], and for lifetime binge-eating behavior 0.65 (95% CI 0.54-0.74). The genetic correlation was estimated as 0.35 (95% CI 0.25-0.46) and the covariance between ADHD and binge-eating behavior was primarily explained by genetic factors (91%). Non-shared environmental factors explained the remaining part of the covariance. CONCLUSIONS: The association between adult ADHD symptoms and binge-eating behavior in females is largely explained by shared genetic risk factors.

RÉSUMÉ

This study examined whether engagement in body talk would interact with weight status (body mass index; BMI) to predict pathological eating behaviors among romantically involved adults. Adults (N = 137, females = 86.86%, average age = 23.50) involved in a romantic relationship were recruited to complete an online survey about their body image, dietary behaviors, and engagement in body talk. Results indicated that engagement in negative body talk was directly related to higher pathological eating (i.e., drive for thinness, dieting, and bulimia symptoms). Positive body talk, on the other hand, had a significant interaction effect with BMI to predict pathological eating. For individuals with a high BMI, high engagement in positive body talk was associated with increased drive for thinness, dieting, and bulimia symptoms. However, for those with a low BMI, high engagement in positive body talk was protective against pathological eating. These findings suggest that while negative body talk is harmful in general, positive body talk is uniquely problematic for individuals of a higher weight status.

RÉSUMÉ

BACKGROUND: Binge eating occurs more frequently in women than in men, and is known to be related to psychological factors such as stress, depression, and anxiety. This study examined the relationship between binge eating and depression, trait anxiety, and perceived stress in Korean adolescents. METHODS: Four hundred girls (aged 17-18 years) from two high schools located in Seoul completed self-report questionnaires. In total, 327 participants returned reliable responses, and were included in the final study. Binge eating was measured using the Bulimic Inventory Test Edinburgh. The questionnaire also included the Perceived Stress Scale (PSS), Trait Anxiety (TA) of State-Trait Anxiety Inventory, Anxiety Sensitivity Inventory (ASI), and Beck Depression Inventory (BDI). RESULTS: The binge-eating group had higher BMI than the control group. The binge-eating group showed higher scores than control on the PSS, BDI, ASI, and TA. The TA was most highly correlated with binge eating. From logistic regression analysis, TA was revealed to be the only factor that raised the risk of binge eating, whereas PSS, BDI, and ASI showed no statistical significance. CONCLUSION: Although binge eating was correlated with perceived stress, depression, and trait anxiety, when their influences were controlled, only binge eating appeared to be associated with trait anxiety.

RÉSUMÉ

This review examines the merits of 'food addiction' as an explanation of excessive eating (i.e., eating in excess of what is required to maintain a healthy body weight). It describes various apparent similarities in appetites for foods and drugs. For example, conditioned environmental cues can arouse food and drug-seeking behaviour, 'craving' is an experience reported to precede eating and drug taking, 'bingeing' is associated with both eating and drug use, and conditioned and unconditioned tolerance occurs to food and drug ingestion. This is to be expected, as addictive drugs tap into the same processes and systems that evolved to motivate and control adaptive behaviours, including eating. The evidence, however, shows that drugs of abuse have more potent effects than foods, particularly in respect of their neuroadaptive effects that make them 'wanted.' While binge eating has been conceptualised as form of addictive behaviour, it is not a major cause of excessive eating, because binge eating has a far lower prevalence than obesity. Rather, it is proposed that obesity results from recurrent overconsumption of energy dense foods. Such foods are, relatedly, both attractive and (calorie for calorie) weakly satiating. Limiting their availability could partially decrease excessive eating and consequently decrease obesity. Arguably, persuading policy makers that these foods are addictive could support such action. However, blaming excessive eating on food addiction could be counterproductive, because it risks trivialising serious addictions, and because the attribution of excessive eating to food addiction implies an inability to control one's eating. Therefore, attributing everyday excessive eating to food addiction may neither explain nor significantly help reduce this problem.

RÉSUMÉ

OBJECTIVE: This study aimed to determine the feasibility and preliminary efficacy of a post-operative telephone-based cognitive behavioral therapy intervention (Tele-CBT) in improving eating pathology and psychosocial functioning. METHODS: Six-month post-operative bariatric surgery patients (n = 19) received six sessions of Tele-CBT. Study outcome variables included binge eating (BES), emotional eating (EES), depressive symptoms (PHQ-9), and anxiety symptoms (GAD-7). RESULTS: Retention was 73.7 % post-intervention. Tele-CBT resulted in significant reductions in mean difference scores on BES, EES-Total, EES-Anxiety, EES-Anger, PHQ9, and GAD7. Tele-CBT patients experienced a mean weight loss of 8.62 ± 15.02 kg between 6-months post-surgery (pre-Tele-CBT) and 12-months post-surgery. CONCLUSIONS: These preliminary results suggest that post-surgery Tele-CBT is feasible and can improve post-surgery symptoms of psychopathology in this uncontrolled study, supporting the need for a randomized controlled trial.
