Updating Prospective Self-Efficacy Beliefs About Cardiac Interoception in Anorexia Nervosa: An Experimental and Computational Study.

Patients with anorexia nervosa (AN) typically hold altered beliefs about their body that they struggle to update, including global, prospective beliefs about their ability to know and regulate their body and particularly their interoceptive states. While clinical questionnaire studies have provided ample evidence on the role of such beliefs in the onset, maintenance, and treatment of AN, psychophysical studies have typically focused on perceptual and 'local' beliefs. Across two experiments, we examined how women at the acute AN (N = 86) and post-acute AN state (N = 87), compared to matched healthy controls (N = 180) formed and updated their self-efficacy beliefs retrospectively (Experiment 1) and prospectively (Experiment 2) about their heartbeat counting abilities in an adapted heartbeat counting task. As preregistered, while AN patients did not differ from controls in interoceptive accuracy per se, they hold and maintain 'pessimistic' interoceptive, metacognitive self-efficacy beliefs after performance. Modelling using a simplified computational Bayesian learning framework showed that neither local evidence from performance, nor retrospective beliefs following that performance (that themselves were suboptimally updated) seem to be sufficient to counter and update pessimistic, self-efficacy beliefs in AN. AN patients showed lower learning rates than controls, revealing a tendency to base their posterior beliefs more on prior beliefs rather than prediction errors in both retrospective and prospective belief updating. Further explorations showed that while these differences in both explicit beliefs, and the latent mechanisms of belief updating, were not explained by general cognitive flexibility differences, they were explained by negative mood comorbidity, even after the acute stage of illness.

Longitudinal outcomes of a work inclusion program in mental health departments in the city of Milan.

BACKGROUND: Work functioning impairment is a key diagnostic and prognostic criterion in patients with psychiatric disorders and work inclusion is a major goal of their therapeutic pathway. Since 2009, the Regional Innovative Program (PIR) TR106, promoted by ASST Fatebenefratelli-Sacco of Milan in collaboration with other Departments of Mental Health and Addictions (DSMDs) in the town of Milan (Italy), has been developing the employment inclusion of psychiatric patients. AIMS: The objective of this study is to evaluate its outcomes over 8 years of observation. METHOD: We reported the results of a retrospective epidemiologic analysis on 2,142 interventions on 1,066 patients recruited, investigating PIR TR106 outcomes per year focusing on different subgroups. We focused on 'positive', 'negative', and 'other' outcomes. RESULTS: We preliminary calculated job maintenance interventions (5%, 107) and excluded these interventions from the overall. We observed 29 job firing (1.4%) and 15 job resignations (0.7%) as negative results (equal to 2.2% of the total) and 388 job hiring (16.6%), 647 traineeships (31.8%), and 413 work formation (20.3%) as positive outcomes (equal to 68.75%). In other outcomes (29.1%) we found 305 dismissals from PIR TR 106 (15%) and transitory outcomes (14.1%).Job hiring increased from 8.9% in 2012 to 23.8 % in 2019 (p < .001), while the dismissals diminished from 26.7% to 13.3% (p < .001). The effectiveness of traineeships in terms of job hiring increased in the ratio of annual job hiring versus job traineeship (+48.8%). The majority of hired patients (15.1%) were affected by a psychotic disorder. A significant hiring increase was observed in patients with psychotic disorders and personality disorders (p < .005). CONCLUSIONS: PIR-TR106 represents a territorial employment inclusion program with progressively increasing effectiveness and specificity, as suggested by changes in outcomes during the 8-year observation. The adaptive capacity and sustainability of the intervention are worth further investigation.

Forearm bisection task suggests an alteration in body schema in patients with functional movement disorders (motor conversion disorders).

OBJECTIVES: To explore potential alterations of the Body Schema, the implicit sensorimotor representation of one's own body, in patients with Functional Movement Disorders (FMD, Motor Conversion Disorders), characterized by neurological symptoms of altered voluntary motor function that cannot be explained by typical medical conditions. This investigation is prompted by the potential dissociation from their reportedly intact sense of ownership. METHODS: 10 FMD patients and 11 healthy controls (HC) underwent the Forearm Bisection Task, aimed at assessing perceived body metrics, which consists in asking the subject, blindfolded, to repeatedly point at the perceived middle point of their dominant forearm with the index finger of their contralateral hand, and a psychometric assessment for anxiety, depression, alexithymia, and tendency to dissociation. RESULTS: FMD patients bisected their forearm more proximally (with an increased shift towards their elbow equal to 7.5%) with respect to HC; average bisection point was positively associated with anxiety levels in the whole sample, and with the tendency to dissociation in the FMD group. CONCLUSIONS: FMD patients perceive their forearm as shorter than HC, suggesting an alteration of their Body Schema. The Body Schema can go through short- and long-term updates in the life course, mainly related to the use of each body segment; we speculate that, despite FMD being a disorder of functional nature, characterized by variability and fluctuations in symptomatology, the lack of sense of agency over a body part might be interpreted by the nervous system as disuse and hence influence the Body Schema, as deficits of organic etiology do.

Early identification of risk for eating disorders in Italian secondary school students: a cross-sectional study.

AIM: Eating disorders are major illnesses that primarily affect adolescents and young adults and seriously threaten public health. Early identification of at-risk individuals and timely initiation of treatment is crucial to improve outcomes. The Inside Out Institute Screener (IOI-S) is a rapid self-administration screening tool for high-risk and early-stage eating disorders. This study aimed to investigate the risk of having an eating disorder in a sample of Italian students by testing the Italian version of the IOI-S. METHODS: A multicentre cross-sectional study was conducted in a population of students aged 12-19 years; validity and reliability of the IOI-Sita were investigated. RESULTS: Four-hundred and ninety-one (81.97%) students were enrolled, 24.85% of whom were found to be at "very high risk" of an eating disorder, according to IOI-Sita. Younger (p<0.001) and female (p<0.001) students had higher risk scores. The EFA confirmed the original monodimensional structure of the tool, S-CVI=0.95%. The Content Validity Index of the scale (S-CVI) was 0.95, ω coefficient was 0.927. DISCUSSION AND CONCLUSIONS: This research confirms the need to screen for eating disorders in Italian youth adequately; the psychometric properties of the IOI-Sita confirm it as a valid and reliable tool for screening high-risk and early-stage eating disorders.

Autistic traits, sensory sensitivity and eating disturbances in a sample of young adults referring to a generalized mental health clinic.

PURPOSE: The relationship between autistic traits and eating disturbances has been given considerable attention over the last decades. The rise of a dimensional approach to psychopathology has expanded the way we think about autism, acknowledging that subthreshold autistic manifestations span across the general population and are more pronounced in psychiatric patients. Here we investigated the prevalence of eating disorders and its potential relationship with autistic traits and sensory sensitivity in a group of patients who were referred for the first time to a mental health outpatient clinic, without a formal diagnosis yet. METHODS: 259 young adults (between 18 and 24 years old) completed: the Eating Attitude Test (EAT-26), the Swedish Eating Assessment for Autism Spectrum Disorders (SWEAA), the Autism Quotient (AQ), the Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R), and the Sensory Perception Quotient-Short Form 35 item (SPQ-SF35). RESULTS: 23.55% of participants scored above the cut-off at the EAT-26, suggesting that they presented a risk for eating disorders and should be assessed by a specialized clinician; associations emerged between hypersensitivity in the touch and vision domain and both the EAT-26 and the SWEAA; the presence of autistic traits was largely associated with eating disturbances. CONCLUSIONS: This study underlines the significance of the eating domain as a central psychopathological feature in the distress experienced by young adults with general psychiatric symptoms and psychological suffering; it adds evidence to the association between autistic traits and eating disorders and opens to new research questions about the role of subthreshold autistic traits in general psychopathology. LEVEL OF EVIDENCE: Level I: Evidence obtained from experimental studies.

Elderly Onset of Functional Motor Disorders: Clinical Correlates from the Italian Registry.

BACKGROUND: Functional motor disorders (FMD) are a frequent neurological condition affecting patients with movement disorders. Commonly described in younger adults, their manifestation can be also associated to an elderly onset. OBJECTIVE: To assess the prevalence and describe the clinical manifestations of FMD with elderly and younger onset and their relationship with demographical and clinical variables. METHODS: We recruited patients with a "clinically definite" diagnosis of FMD from the Italian Registry of FMD. Patients underwent extensive clinical assessments. For elderly onset, we set a chronological cut-off at 65 years or older according to WHO definition. Multivariate regression models were implemented to estimate adjusted odds ratio of elderly FMD onset related to clinical characteristics. RESULTS: Among the 410 patients, 34 (8.2%) experienced elderly-onset FMD, with a mean age at onset of 70.9 years. The most common phenotype was tremor (47.1%), followed by gait disorders, weakness, and dystonia (29.4%, 23.5%, 14.7%, respectively). Eleven elderly patients had a combined phenomenology: 9 exhibited two phenotypes, 2 had three phenotypes. Weakness was isolated in 3/8 patients and combined with another phenotype in 5/8, manifesting as paraplegia (n = 4); upper limb diplegia (n = 2), hemiparesis/hemiplegia (n = 1), and tetraparesis/tetraplegia (n= 1). Non-motor and other functional neurological disorders occurred more frequently in the younger group (89.1%) than the elderly (73.5%). Neurological and non-neurological comorbidities were more prevalent in the elderly group (82.4%) as opposed to the younger (32.7%). In a multivariate regression analysis, elderly-onset FMD was significantly associated with neurological comorbidities, including parkinsonism (OR 6.73) and cerebrovascular diseases (OR 5.48). CONCLUSIONS: These results highlight the importance of achieving an accurate diagnosis of FMD in the elderly, as it is crucial for effectively managing FMD symptoms and addressing neurological comorbidities.
