Nutritional Assessment of Children and Adolescents with Atypical Anorexia Nervosa: A Preliminary Longitudinal Investigation Using the 24-h Dietary Recall.

Atypical Anorexia Nervosa (AAN) is a Feeding and Eating Disorder characterized by fear of gaining weight and body image disturbance, in the absence of significantly low body weight. AAN may present specific clinical and psychopathological features. Nonetheless, the literature lacks data concerning the nutritional characteristics and body composition of children and adolescents with AAN and their variation over time. Case series, including 17 children and adolescents with AAN. All the patients were assessed at the first evaluation (T0) with a standardized dietary assessment (24 h Dietary Recall, 24 hDR). Nutritional data were compared with European dietary reference values (DRVs). Body composition parameters (weight, fat mass, fat-free mass) and their changes over time at two (T1) and six (T2) months were collected as well, using a Bioelectrical impedance analysis (Wunder WBA300 with four poles and foot contact; impedance frequency 50 kHz 500 μA; impedance measurement range 200~1000 Ω/0.1 Ω). The included individuals presented eating behaviors oriented towards significantly low daily energy intake (p < 0.001) compared with DRVs set by the European Food Safety Authority (EFSA) (with low carbohydrates and fats), and increased proteins (p < 0.001). A longer latency before observation (illness duration before observation) correlated with a negative change in weight. Body composition parameters were described, with no significant changes across the six-month outpatient assessment. This is the first research to systematically assess the body composition and nutritional features of a group of individuals with AAN in the developmental age. Further research should assess the effect of targeted treatment interventions on body composition and nutritional features.

From gut to brain: A network model of intestinal permeability, inflammation, and psychotic symptoms in schizophrenia.

Impaired intestinal permeability has recently been suggested as a possible source of chronic inflammation in schizophrenia, but its association with specific psychopathological features remains uncertain. This study aimed to explore the interaction between intestinal permeability, inflammation, and positive and negative symptoms in schizophrenia using a network analysis approach. The study sample comprised 281 adults with schizophrenia (age 40.29 ± 13.65 years, 63.0 % males), enrolled in a cross-sectional observational study assessing intestinal permeability. We estimated the network with a Gaussian graphical model, incorporating scores from 14 individual items of the Positive and Negative Syndrome Scale (PANSS), along with body mass index (BMI), and plasma C-reactive protein (CRP) and lipopolysaccharide-binding protein (LBP) levels. We calculated strength centrality and expected influence and used bridge centrality statistics to identify the bridge nodes. Distinct but highly interconnected clusters emerged for positive and negative symptoms. The biological variables were closely associated with each other. LBP was positively linked with CRP and BMI, but only indirectly connected to psychopathology. CRP exhibited direct positive relationships with various PANSS items and bridged LBP and BMI with psychopathology. Bridge nodes included Conceptual Disorganisation (P2), Active Social Avoidance (G16), Suspiciousness/Persecution (P6), and CRP. These findings support the role of gut-derived inflammation as a mechanism underlying greater symptom severity in schizophrenia and emphasise the importance of addressing dietary habits not only to enhance physical health but also to contribute to improving psychotic symptoms.

Cognitive dysfunction and psychopathology: a cohort study of adults with intellectual developmental disorder.

Cognitive impairment of intellectual developmental disorders (IDD) is determined by several different combinations of specific cognitive alterations. People with IDD present a rate of mental health problems that is up to 4 times higher than that of the general population. Despite this, the relationship between specific cognitive dysfunctions and co-occurring mental disorders has not been adequately studied. The aim of the present paper is to investigate the association between specific cognitive dysfunctions and specific psychiatric symptoms and syndromes in people with IDD. One hundred and twenty adults with mild to moderate IDD living in residential facilities underwent a clinical and instrumental assessment for specific cognitive and psychopathological features. Participants with IDD and ASD have significantly lower scores compared to those without respect to who has not the diagnosis on the Processing Speed Index (PSI) and Perceptual Reasoning Index (PRI) on the WAIS-IV and higher time scores on the TMT A. Moreover, there is a significant association between years of hospitalisation and TMT B and TMT BA time scores; the longer a participant with IDD was hospitalised, the worse their performance on the TMT. Although not statistically significant, many psychopathological clusters showed substantial cognitive profiles. Although further research is needed, neuropsychological and IQ tests scores seem to be differently associated to various psychopathological conditions co-occurring with IDD, and with ASD especially. Cognitive assessment seems to support diagnosis and treatment of psychopathological co-occurrences in persons with IDD, also in consideration of indirect implications including a better knowledge of the patient's characteristics beyond IQ deficit.

Changes in brain structure in people with gaming disorder. A review of neuroimaging studies.

This review aims to summarise the current knowledge on structural brain changes among people diagnosed with gaming disorder and the resulting clinical implications. The review will show the theoretical psychological and neurobiological models of computer gaming disorder in conjunction with the results of structural neuroimaging studies. Previous epidemiological studies indicate that the prevalence of gaming disorder in the population may reach approx. 2%. Researchers indicate that the aetiopathogenesis of computer game use disorder is complex and includes psychological, social, as well as neurological and hormonal factors. From the perspective of psychological research exploring gaming disorder, it can be concluded that a person has certain specific psychopathological features and/or symptoms, which, through mediating factors, such as the inability to cope with stress or negative emotions, influence the formation of the symptoms of the disorder. In the context of the neurobiology of behavioural addictions, researchers point to disorders in the mesocorticolimbic reward system, which is influenced by dysfunctional neuronal mechanisms of emotion and stress regulation. When describing structural changes in the brain, researchers most often report differences in the volume of grey matter, which include areas of the dorsolateral prefrontal cortex, temporooccipital cortex, superior and posterior parietal cortex, anterior cingulate cortex, cerebellum, insular cortex, limbic system, and basal ganglia.

Exploring the Link between ADHD and Obesity: A Focus on Temperament.

Multiple studies support the relationship between ADHD and overweight/obesity in youth. Different mechanisms may be involved, such as temperamental and psychopathological factors. The aim of this study was to test the hypothesis that specific temperamental and psychopathological dimensions could mediate the relationship between ADHD and obesity. The sample included 100 children and adolescents (78 males and 22 females; age range 6 to 18 years; mean age 9.90 ± 2.5 years). The assessment procedure included Conners' Parent Rating Scale-Long (CPRS-R:L) as the inclusion criterion for ADHD diagnosis, the Child Behavior Checklist (CBCL), a dimensional measure for psychopathology, and the Junior Temperament and Character Inventory, which describes four temperamental dimensions: novelty seeking (NS), harm avoidance (HA), reward dependence (RD), and persistence (P). While in the whole ADHD sample, the highest scores were found in NS and the lowest in P, ADHD with overweight/obesity, compared to ADHD with normal weight, showed higher HA and RD, lower NS, and higher CBCL Internalizing scores. These findings suggest that ADHD youth with overweight/obesity present specific temperamental and psychopathological features compared to those without overweight/obesity. If confirmed in larger samples, using a control group without ADHD, these temperamental and psychological features may be helpful for an earlier recognition of ADHD patients at higher risk for obesity, and may represent possible targets for temperament-based preventive interventions and tailored treatment programs. These features should be included in the routine assessment of children and adolescents with ADHD and/or are overweight/obese.

Immunotherapy with corticosteroids in anti-neural autoantibody-associated cognitive impairment: Retrospective case series.

BackgroundAnti-neural autoantibody-associated cognitive impairment is an increasing phenomenon in memory clinics deserving more attention to applying immunotherapy such as methylprednisolone to improve cognition. Our study aims to investigate the usefulness of intravenous high-dosage corticosteroids in a small cohort of patients suffering from anti-neural autoantibody-associated cognitive impairment.Materials and methodsWe included in our retrospective case series seven patients presenting diverse neural autoantibodies and cognitive impairments varying from a mild impairment to dementia. We conducted neuropsychological and psychopathological investigations before and after the application of high intravenous methylprednisolone therapy over a 6-month period. Neuropsychological function was assessed by the CERAD (Consortium to Establish a Registry for Alzheimer’s Disease) test battery. Patients were also characterized by assessing their patient files for demographic and clinical data.ResultsThe patients’ cognitive subdomains did not improve according to CERAD in their z-scores before and after immunotherapy. We noted a non-significant trend toward an improvement in semantic fluency and verbal memory consolidation. Patients did not do worse in 4 of 12 (33%) cognitive subdomains in the CERAD test battery. Furthermore, mood dysfunction lessened as a non-significant trend in specific psychopathological features such as reduced affective symptoms, loss of drive, and ruminations. Affective symptoms, loss of drive and ruminations were reduced by 43% after immunotherapy.DiscussionOur small pilot study revealed no relevant alleviation of cognitive dysfunction in patients with neural autoantibodies. However, mood dysfunction became less obvious in specific functions concerning affect, drive, and rumination. However, we do not know whether methylprednisolone affects mood dysfunction, as some patients were taking antidepressant drugs at the same time. Our results might indicate that methylprednisolone immunotherapy is associated with impeding the progression of cognitive dysfunction and reducing mood dysfunction. Further large-scale, placebo-controlled studies in a more homogeneous patient population presenting a uniform pattern of neural autoantibodies should be undertaken.

Treatment response classes in major depressive disorder identified by model-based clustering and validated by clinical prediction models

The identification of generalizable treatment response classes (TRC[s]) in major depressive disorder (MDD) would facilitate comparisons across studies and the development of treatment prediction algorithms. Here, we investigated whether such stable TRCs can be identified and predicted by clinical baseline items. We analyzed data from an observational MDD cohort (Munich Antidepressant Response Signature [MARS] study, N = 1017), treated individually by psychopharmacological and psychotherapeutic means, and a multicenter, partially randomized clinical/pharmacogenomic study (Genome-based Therapeutic Drugs for Depression [GENDEP], N = 809). Symptoms were evaluated up to week 16 (or discharge) in MARS and week 12 in GENDEP. Clustering was performed on 809 MARS patients (discovery sample) using a mixed model with the integrated completed likelihood criterion for the assessment of cluster stability, and validated through a distinct MARS validation sample and GENDEP. A random forest algorithm was used to identify prediction patterns based on 50 clinical baseline items. From the clustering of the MARS discovery sample, seven TRCs emerged ranging from fast and complete response (average 4.9 weeks until discharge, 94% remitted patients) to slow and incomplete response (10% remitted patients at week 16). These proved stable representations of treatment response dynamics in both the MARS and the GENDEP validation sample. TRCs were strongly associated with established response markers, particularly the rate of remitted patients at discharge. TRCs were predictable from clinical items, particularly personality items, life events, episode duration, and specific psychopathological features. Prediction accuracy improved significantly when cluster-derived slopes were modelled instead of individual slopes. In conclusion, model-based clustering identified distinct and clinically meaningful treatment response classes in MDD that proved robust with regard to capturing response profiles of differently designed studies. Response classes were predictable from clinical baseline characteristics. Conceptually, model-based clustering is translatable to any outcome measure and could advance the large-scale integration of studies on treatment efficacy or the neurobiology of treatment response.

Melancholic-Like behaviors and circadian neurobiological abnormalities in melatonin MT1 receptor knockout mice.

Background:Melancholic depression, described also as endogenous depression, is a mood disorder with distinctive specific psychopathological features and biological homogeneity, including anhedonia, circadian variation of mood, psychomotor activation, weight loss, diurnal cortisol changes, and sleep disturbances. Although several hypotheses have been proposed, the etiology of this disorder is still unknown.Methods:Behavioral, electrophysiological and biochemical approaches were used to characterize the emotional phenotype, serotonergic and noradrenergic electrical activity, and corticosterone in melatonin MT1 receptor knockout mice and their wild type counterparts, during both light and dark phases.Results:Melatonin MT1 receptor knockout mice have decreased mobility in the forced swim and tail suspension tests as well as decreased sucrose consumption, mostly during the dark/inactive phase. These mood variations are reversed by chronic treatment with the tricyclic antidepressant desipramine. In addition, MT1 receptor knockout mice exhibit psychomotor disturbances, higher serum levels of corticosterone the dark phase, and a blunted circadian variation of corticosterone levels. In vivo electrophysiological recordings show a decreased burst-firing activity of locus coeruleus norepinephrine neurons during the dark phase. The circadian physiological variation in the spontaneous firing activity of high-firing neuronal subpopulations of both norepinephrine neurons and dorsal raphe serotonin neurons are abolished in MT1 knockout mice.Conclusions:These data demonstrate that melatonin MT1 receptor knockout mice recapitulate several behavioral and neurobiological circadian changes of human melancholic depression and, for the first time, suggest that the MT1 receptor may be implicated in the pathogenesis of melancholic depression and is a potential pharmacological target for this mental condition.

Magnesium in drug-naïve patients with a short-duration, first episode of major depressive disorder: impact on psychopathological features

Plasma magnesium concentration changes are seen in major depressive disorder (MDD). Dysregulation of magnesium homeostasis is associated with the severity of depression and specific psychopathological features including apathy, anxiety, irritability, fatigue and weakness. Results from studies on magnesium concentrations in MDD patients are inconsistent, and the evidence for magnesium ions being associated with specific features of depression and anxiolytic effects is unclear. This study was designed to examine whether and to what extent plasma magnesium is related to the psychopathological features of depression including severity of symptoms and specific psychopathological aspects. Plasma magnesium levels were studied in this cross-sectional, case-control study and involved 20, non-late-life adults who were treatment-naïve, short- duration, first episode, MDD patients, and 20 age- and sex-matched, healthy controls. Psychometric evaluations were performed using the Hamilton Rating Scale for Depression (HAMD-17) and the Spielberger State-Trait Anxiety Inventory (STAI). A significantly higher magnesium (p = 0.016) concentration was observed in MDD patients compared to controls. No significant correlations were observed between magnesium concentrations and the total HAMD-17 score or with regard to the specific core depression, insomnia, anxiety or somatic HAM-D psychopathological features. In addition, no significant correlations were found between magnesium concentrations and STAIX-1 and STAIX-2 scores. The present study provides evidence of hypermagnesaemia in drug-naïve patients with a short-duration, first episode of MDD. A cross-sectional analysis adds to the evidence linking plasma magnesium concentrations with psychopathology of MDD during early stages of the disease although with no correlations between plasma magnesium concentrations and psychopathology including severity of symptoms and specific psychopathological features.

Obsessive-compulsive disorder with psychotic features: psychopathological and personological aspects

The aims of this study are to analyze psychopathological relations between obsessive-compulsive and psychotic symptoms in a group of patients with obsessive-compulsive disorder (OCD), and to verify if the obsessive subgroup with psychotic features can be considered as a distinct OCD subtype. The study sample included 68 patients with OCD who were divided into two different groups (OCD with and without psychotic features). All subjects completed the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Scale for the Assessment of Positive Symptoms (SAPS), the Hamilton Depression Rating Scale (HDRS), and the Structured Interview for DSM-IV Personality Disorders (SIDP-IV). Twenty subjects (29.4%) were affected by OCD with psychotic features. They were characterized by an earlier onset of obsessive illness (p<0.05), a more frequently chronic course (p<0.01), an "atypical" obsessive-compulsive symptomatology (with poor insight and anxiety) (p<0.001), higher levels of depression (p<0.05), and a higher prevalence of schizotypal personality disorder (p<0.01). Patients affected by OCD with psychotic symptoms appear to be a distinct subtype of obsessive-compulsive disorder, characterized by a set of specific psychopathological and personological features. However, the finding that these subjects have a higher prevalence of schizotypal personality disorder seems to suggest that they can be considered as a peculiar clinical subset belonging to the schizophrenia-spectrum disorders rather than a group of obsessive individuals placed on the most serious clinical extreme of the OCD spectrum.

Glutathione S-transferase alpha 1 risk polymorphism and increased bilateral thalamus mean diffusivity in schizophrenia

Oxidative damage in brain cells is one of the factors hypothesized to be involved in the pathogenesis of schizophrenia. Glutathione S-transferase (GST) A1*B polymorphism, a genotype associated with a higher risk of oxidative damage, is associated with increased frequency of schizophrenia diagnosis. Thus, here we studied Glutathione S-transferase (GST) A1 polymorphism and diffusion tensor imaging-mean diffusivity (MD) data on deep grey matter brain structures in 56 patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revised (DSM-IV-TR) schizophrenia. Clinical diagnosis and psychopathological symptom severity were assessed by using the Structured Clinical Interview for DSM-IV-TR (SCID-P) and the Scales for Assessment of Positive and Negative Symptoms (SAPS and SANS). Results confirmed that patients with schizophrenia who were carriers of the GSTA1 *B risk allele had an increased MD in bilateral thalami and increased severity of auditory and global hallucinations in comparison with non-B carriers. Thus, oxidative stress associated factors may be implicated in specific mechanisms of schizophrenia such as altered microstructure of the thalami and specific psychopathological features of auditory hallucinations.

No Correlation between Lithium Serum Levels and Psychopathological Features during the Euthymic Interval of Patients with Recurrent Affective Disorder

The aim of this prospective study was to investigate the influence of lithium serum levels on subclinical psychopathological features during the euthymic interval in patients with an affective disorder. The study included 54 patients with a recurrent affective disorder undergoing a continuous prophylactic lithium treatment (31 unipolar, 23 bipolar). The observation period lasted for 2 years and included 332 visits. Visits consisted of a detailed interview, a continuous measurement of lithium levels and the collection of validated scales including HAMD, YMRS, CGI, VAMS and the SCL-90R. Several correlations between lithium serum levels and different psychopathological features during the euthymic interval were calculated on an individual patient basis and on a group basis to reveal generally occurring correlations. No generally occurring significant correlations between lithium serum levels and specific psychopathological features were found. Only on a single patient level, 32 significant correlations between lithium level and specific psychopathological features were found, partly indicating a negative and partly indicating a positive influence of higher lithium levels on psychopathological symptoms. Nevertheless, in the group analyses no significant correlations were found. Higher lithium levels were not associated with an improved psychopathological status, but they were not associated with a worse status (due to a higher burden of side effects) either. According to the literature there is currently no strong evidence to treat patients with a higher lithium level. It is recommended to start with a lower level and to continue with individual adjustments in accordance to prophylactic efficacy and tolerability.

Psychopathology factors in first-episode affective and non-affective psychotic disorders

Background Since the onset, prevalence, and course of specific psychopathological features rarely have been analyzed simultaneously from the start of dissimilar psychotic illnesses, we compared symptom-clusters in first-episode DSM-IV affective and non-affective psychotic disorders. Methods Subjects ( N = 377) from the McLean–Harvard First Episode Project hospitalized for first-lifetime primary psychotic illnesses were followed prospectively for 2 years to verify stable DSM-IV diagnoses. We ascertained initial symptoms from baseline SCID and clinical assessments, applying AMDP and Bonn psychopathology schemes systematically to describe a broad range of features. Final consensus diagnoses were based on intake and follow-up SCID assessments, family interviews, and medical records. Factor-analytic methods defined first-episode symptom-clusters (Factors), and multiple-regression modeling related identified factors to initial DSM-IV diagnoses and to later categories ( affective, non-affective, or schizoaffective disorders). Results Psychopathological features were accommodated by four factors: I represented mania with psychosis; II a mixed depressive-agitated state; III an excited-hallucinatory-delusional state; IV a disorganized-catatonic-autistic state. Each factor was associated with characteristic prodromal symptoms. Factors I and III associated with DSM-IV mania, II with major depression or bipolar mixed-state, III negatively with delusional disorder, IV with major depression and negatively with mania. Factors I and II predicted later affective diagnoses; absence of Factor I features predicted non-affective diagnoses, and no Factor predicted later schizoaffective diagnoses. Conclusion The findings contribute to descriptive categorizations of psychopathology from onset of dissimilar psychotic illnesses. This approach was effective in identifying and subtyping affective psychotic disorders early in their clinical evolution, but non-affective and schizoaffective conditions appear to be more complex and unstable.

Features Associated With Laxative Abuse in Individuals With Eating Disorders

Laxative abuse is common in patients with anorexia and bulimia nervosa and has been associated with longer duration of illness, suicide attempts, impulsivity, and greater eating and general psychopathology. We explored the extent to which laxative abuse was associated with specific psychopathological features across eating disorder subtypes. Participants were 1021 individuals from the multisite, International Price Foundation Genetic Studies. Axis I disorders, personality disorders and traits, and obsessive compulsive features were assessed. Laxative abuse was associated with worse eating disorder and general psychopathology and higher prevalence of borderline personality disorder (BPD). Symptom level analyses revealed that specific features of BPD, including suicidality and self-harm, feelings of emptiness, and anger, were most strongly associated with laxative abuse. The function of laxative abuse may differ across individuals with eating disorders, alternatively serving as a method of purging and a form of self-harm.

Factors related to severity of vomiting behaviors in bulimia nervosa

Assessments of the severity of vomiting (weekly frequency), depressive and eating-related psychopathology, anger level and management, and personality dimensions were used to characterize patients with bulimia nervosa binge purging type (BN-BP). The sample comprised 130 outpatients with BN and 130 control women. The Eating Disorder Inventory-2 (EDI-2), the State-Trait Anger Expression Inventory, the Beck Depression Inventory, and the Temperament and Character Inventory (TCI) were administered to all patients. The Self-Directedness dimension of the TCI and the Bulimia subscale of the EDI-2 were the strongest predictors of the severity of bulimic behavior; anger levels and anger expression were not so strongly related to illness severity. A more severe form of bulimic symptomatology probably has substrata in specific character deficits (low Self-Directedness on the TCI) and particular psychopathological features (high bulimia on the EDI-2). Patients with a high frequency of vomiting need specific therapeutic interventions to enhance the character dimension of Self-Directedness.

Psychopathological and clinical features of outpatients with an eating disorder not otherwise specified.

In order to investigate similarities and differences between Eating Disorder Not Otherwise Specified (EDNOS) and Anorexia Nervosa (AN) and Bulimia Nervosa (BN), we studied a consecutive series of 189 female outpatients attending two Eating Disorder Units. The data were collected by means of interviews (Eating Disorder Examination, EDE 12.0D), the Structured Diagnostic Interview for DSM III-R, (SCID), and self-reported questionnaires (Beck Depression Inventory, BDI, and State and Trait Anxiety Inventory, STAI 1-2). The diagnosis of EDNOS was as frequent as that of AN and BN (43.8% versus 43.2%). There were no significant differences between EDNOS and AN/BN patients in terms of their general and specific psychopathological features, but significant differences were observed between bulimic-like and anorectic-like EDNOS patients, as well as between those with AN and BN. In conclusion, in our clinical setting, the patients with EDNOS and those with typical eating disorders have similar psychopathological features, thus suggesting that EDNOS patients should be further divided into two groups, anorectic-like (similar to AN) and bulimic-like (similar to BN) patients.

Serotonergic and noradrenergic function in depression: clinical correlates

The present study was conducted in order to investigate the relationships between central noradrenergic (NA) and serotonergic (5-HT) function and clinical characteristics of a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. We measured growth hormone response (ΔGH) to clonidine (CLO) (an α2 NA agonist), as an index of central NA function, and prolactin response (APRL) to d-fenfluramine (d-FEN) (a specific 5-HT releaser/uptake inhibitor), as an index of central 5-HT function, in 53 medication-free depressed inpatients. On the basis of their CLO and d-FEN test responses, patients were classified into 4 groups. Group 1 (blunted ΔPRL(d-FEN) alone [11 %]) was characterized by a recent violent suicide attempt, a high degree of medical damage, and mild anxiety. Group 2 (blunted ΔGH(CLO) alone [32%]) was characterized by an absence of a history of suicide attempt and by severe anxiety. Group 3 (combination of blunted ΔGH(CLO) and APRL(d-FEN) [18%]) was characterized by a history of suicide attempts, total duration of the illness of over W years, age over 40 years, and more than 3 previous hospitalizations. Group 4 (no abnormality [39%]) had no specific clinical profile. These results suggest that, in depression, specific psychopathological features may be linked to 5-HT and/or NA dysfunction. However, our results also suggest that NA and/or 5-HT dysfunction are less likely to be the primary cause of mood disorders but are more indicative of failure of compensatory mechanisms involved in affective homeostatic processes.

Public and private self-consciousness as specific psychopathological features

Abstract Public self-consciousness (PUBSC) and private self-consciousness (PRISC) represent aspects of dispositional self-directed attention. The aim of the present study was to investigate whether four clinical groups, namely patients with a diagnosis of social phobia, panic disorder, obsessive–compulsive disorder or bulimia nervosa, and normal controls differentiated on the basis of their PUBSC and PRISC scores. Results indicated that both PUBSC and PRISC are extremely elevated in patients with social phobia. Patients with panic disorder and patients with obsessive–compulsive disorder score somewhere between social phobics and normal controls on PUBSC and PRISC scales. Bulimics had significantly higher PUBSC values than both controls and patients with panic disorder, but had lower values than social phobics. Compared to normal controls, bulimics showed no elevated PRISC scores. In addition, contrary to the other groups, PUBSC and PRISC seem to be unrelated in bulimics. Thus, PUBSC and PRISC appear to be specific psychopathological features for German females when comparing groups with different mental disorders and normal controls.
