An attachment perspective on the risk for psychosis: Clinical correlates and the predictive value of attachment patterns and mentalization

Psychological impairment in inflammatory bowel diseases: the key role of coping and defense mechanisms

A comprehensive investigation of psychological features in chronic patients is very important for tailoring effective treatments. In this study we tested anxiety, depression, health related quality of life (HR-QoL), alexithymia, coping styles, and defense mechanisms, in eighty-four patients with Crohn disease (CD) and ulcerative colitis (UC). Participants reported low to moderate HRQoL and anxiety, apart from alexithymia. Women experienced lower QoL and higher levels of anxiety and depressive symptoms. Coping and defense strategies were related to distress symptoms and QoL. Positive attitude and principalization, showed negative associations with depression, anxiety and alexithymia and were also found to be associated with mental health. CD patients used significantly more turning against objects (p=0.02) and projections (p=0.01) and UC patients used more reversal (p=0.04). Elderly women showed higher anxiety symptoms and lower perceived QoL. Multiple regression analysis revealed anxiety and depression were independently associated with QoL. Significant differences emerged in defense styles among CD and UC. CD participants used more maladaptive coping and defense styles which were related to mental distress, depression and anxiety, together with higher level of alexithymia. Findings suggest that psychological aspects play a key role in mental health in patients suffering from inflammatory bowel diseases. A multi-integrated clinical strategy including psychotherapeutic interventions should be considered in treating CD and UC.

The catcher in the mind: validation of the brief-mentalized affectivity scale for adolescents in the Italian population

The concept of mentalized affectivity (MA) encompasses the dimensions of identifying, processing, and expressing emotions and describes the process of making sense of and reevaluating one's affects in light of autobiographical memory. This construct was developed within the theoretical framework of mentalization and, due to its interpersonal nature, added further complexity to the emotion regulation construct. This research aimed to examine the factor structure and psychometric properties of the Brief-Mentalized Affectivity Scale for adolescents (B-MAS-A) on an Italian sample of young people (aged 13-19 years). Data were collected using non-probabilistic sampling and an online survey. Participants were asked to complete a large battery of instruments, including the B-MAS-A, the Toronto Alexithymia Scale, the Reflective Functioning Questionnaire, the Epistemic Trust, Mistrust, and Credulity Questionnaire, the Strengths and Difficulties Questionnaire, and the General Self-Efficacy Scale. In study 1, factor analyses carried out on a total sample of 566 adolescents identified 3 distinct dimensions of the same components of MA found in the adult population: i) identifying; ii) processing; iii) expressing emotions. The subscales showed excellent internal consistency. Study 2 (involving a subsample of 288 participants) demonstrated good levels of construct and criterion validity. These results confirm that the B-MAS-A represents a valid and robust instrument for assessing the complex and multifaceted characteristics of MA in adolescents. The B-MAS-A can make a significant contribution to clinical practice and research and encourage systematic studies on MA in psychotherapy, taking into account the developmental stage of adolescence.

I don't understand how I feel: mediating role of impaired self-mentalizing in the relationship between childhood adversity and psychosis spectrum experiences

Introduction

Childhood adversity is associated with the severity of multiple dimensions of psychosis, but the mechanisms underpinning the close link between the two constructs is unclear. Mentalization may underlie this relationship, as impaired mentalizing is found in various stages of the psychosis continuum. Nonetheless, the differential roles of self- and other-mentalizing in psychosis are not well understood.

Methods

Parallel multiple mediation was conducted for the relationship between a diverse range of childhood adversity types, including intentional and nonintentional harm, and schizotypy (positive, negative, disorganized), psychotic-like experiences (PLE) and paranoia via self-mentalizing (attention to emotions and emotional clarity) and other-mentalizing in n = 1,156 nonclinically ascertained young adults.

Results

Significant parallel multiple mediation models were found for all psychotic outcomes except negative schizotypy. The associations between intentionally harmful childhood adversity and psychotic outcomes were significantly mediated by increased attention to emotions for most models and decreased emotional clarity for some models. No significant mediation was found for parental loss. Paternal abuse was only mediated by attention to emotions whereas the effects of maternal abuse were mediated by attention to emotions and emotional clarity. Other-mentalizing only showed mediating effects on one of thirty models tested.

Conclusion

Results highlight the mediating role of impaired self-mentalizing in the association between childhood adversity and psychosis. This is consistent with disturbances of self-concept and self-boundary characterizing, in particular, the positive dimension of psychosis. Maternal versus paternal figures may contribute differentially to the development of mentalizing. These results could inform future preventative interventions, focusing on the development and maintenance of self-mentalizing.

At-risk mental states and personality traits: A cluster analysis approach on a group of help-seeking young adults

INTRODUCTION

Research on the relationship between personality and psychosis onset is growing, with the goal of preventing or intervening early in patients' vulnerability. The identification of individuals with at-risk mental states has enabled the development of early intervention strategies, such as Programma 2000, a youth mental health service that was implemented in Milan (Italy).

AIMS

Focusing on the 18-25 age range-the time window with the highest incidence of psychotic onset-this study aims to identify the personality traits that may characterize the at-risk mental states and the social functioning of a group of help-seeking young adults.

METHODS

The sample includes 169 people (48.5% males and 51.5% females). Data were collected during an initial assessment that comprised the Social and Occupational Functioning Assessment Scale, the Personality Inventory for DSM-5, the Checklist ERIraos and a clinical session.

RESULTS

Results identified a three-cluster solution based on the Checklist scores: Cluster 1 'Not at psychotic risk'; Cluster 2 'At intermediate risk'; Cluster 3 'With psychotic onset'. The multivariate analysis of the variance of personality traits shows significant differences among the clusters in negative affect, detachment and disinhibition. Higher scores in these traits may distinguish individuals, not at psychotic risk from those at intermediate risk or with psychotic onset. Moreover, social functioning was found to be negatively associated with clusters of psychotic risk.

CONCLUSION

Findings from this study highlighted the need to evaluate personalized interventions targeting such personality traits that could prevent psychotic transition and promote psychological well-being.

Reflective functioning and dissociative experiences: A comparison study between adolescents at "high-risk" of psychosis and healthy controls

Background

Despite the established contribution to psychological well-being in young subjects, the investigation of reflective functioning and dissociative experiences in help-seekers adolescents still appears an unmet need.

Objective

The study aimed to assess reflective functioning and dissociative symptoms in help-seekers adolescents, and compare them to gender-matched healthy controls.

Methods

The Reflecting Functioning Questionnaire (RFQ) was used to investigate mentalizing; the Adolescent Dissociative Experience Scale (A-DES) was used to explore dissociative symptoms.

Results

The study involved 102 adolescents (mean age 18.06 ± 1.78 years), split into "help-seekers" (N= 51; mean age 19 ± 1.98 years) and healthy controls (N= 51; mean age 17.12 ± 0.84). "Help-seekers" adolescents showed lower RFQ-certainty scores (mean 3.39 ± 2.47), compared to healthy controls (mean 6.73 ± 5.01). Furthermore, "help-seekers" adolescents reported higher scores on RFQ-uncertainty (mean 7.73 ± 4.38), compared to healthy controls (mean 5.14 ± 4.17), which indicates a greater lack of knowledge about mental states (hypomentalizing). Eventually, "help-seekers" adolescents showed significantly worse dissociative symptoms (A-DES total mean score 3.49 ± 2.04), compared to healthy controls (A-DES total mean score 2.06 ± 1.43).

Conclusion

The importance of an assessment in early adolescence denotes a topic of increasing concern, in order to identify failures in reflective functioning and the onset of dissociative experiences among help-seekers adolescents, toward the implementation of tailored psychological interventions.

Mentalizing in individuals with state and trait risk for psychosis: a systematic review

Background

Mentalization is an umbrella concept defined as the ability to interpret one's and others' mental states. Previous studies have hypothesized that mentalization may be a crucial resilience factor that significantly moderates the likelihood of developing psychotic disorders in individuals with both state and trait risk factors for the illness.

Purpose

The study reviews the role of mentalizing abilities (e.g., reflective functioning, Theory of Mind (ToM), and metacognition) in young adults with At-Risk Mental States (ARMS) and schizotypal traits. Specifically, the objective is to include articles that (a) evaluate the links between low mentalizing and both state (ARMS/CHR) and trait (schizotypy) risk for psychosis (b) compare the differences in mentalizing abilities between individuals with ARMS, schizotypy, full-blown psychosis, and healthy controls.

Method

Electronic databases (PsycINFO, PubMed, Scopus, and Google Scholar) were used to search for articles, while Rayyan was employed to facilitate the screening and selection of studies. Eligible studies are original English-language; peer-reviewed research articles on populations that met validated risk diagnostic criteria for psychosis, ARMS, and healthy controls; empirical studies evaluating the association or differences between psychotic risk and mentalizing abilities. Non-English language studies, the ones not considering state or trait risk for psychosis, and qualitative studies were excluded. After the application of the PRISMA checklist and the inclusion and exclusion criteria previously mentioned, 10 articles were extracted. The systematic review has been registered on Prospero (CRD42023397594).

Results

Low levels of reflective functioning and metacognition may predict a transition to psychosis. In addition, reflective functioning and metacognitive impairments are associated with attenuated psychotic symptoms in both state risk groups and in non-clinical individuals with schizotypal traits. Concerning ToM tasks, mixed results emerged.

Conclusion

The results obtained from the review suggest that the application of strategies to attenuate maladaptive metacognitive beliefs and low mentalization may be equally effective in improving psychotic symptoms. The assessment of mentalization and metacognition could potentially provide additional prognostic value over factors predisposing to psychosis. Good mentalization and metacognition functioning should be considered as protective factors able to minimize the transition to psychosis.

Mentalizing in a movie for the assessment of social cognition (MASC): the validation in a taiwanese sample

BACKGROUND

The present study evaluated the psychometrics properties of a sensitive video-based test used in the evaluation of mentalizing skills, that is, the Movie for the Assessment of Social Cognition-Taiwanese version (MASC-TW).

METHODS

We recruited two independent samples of nonclinical participants (N = 167) and adult patients with schizophrenia (N = 41). The MASC-TW and two other social cognition measures, namely the Chinese version of Theory of Mind task (ToM) and the Taiwanese version of the Diagnostic Analysis of Nonverbal Accuracy-2 (DANAV-TW-2), and an executive function measure of the Wisconsin Card Sorting Test (WCST), were administered to both groups.

RESULTS

The MASC proved to be a reliable measure of mentalizing capacity, high Cronbach's α value of 0.87. The intraclass correlation coefficient for the MASC-TW total correct scores was 0.85 across three waves of data collection. Across the entire sample, the scores on the MASC-TW were significantly correlated with verbal and nonverbal scores for the ToM task and recognition of facial and prosodic emotion on the DANAV-TW-2. Both executive function and emotion recognition emerged as noteworthy predictors of mentalizing, indicating that these two variables might play crucial roles in the development of mentalizing capacities. Finally, a receiver operating characteristic analysis revealed that in patients with schizophrenia, the MASC was the most accurate discriminator of diagnostic groups, highlighting the validity of the MASC.

CONCLUSIONS

Overall, the MASC-TW is an ecologically valid and useful tool for assessing mentalizing abilities in a Taiwanese population.

The role of mentalizing in the relationship between schizotypal personality traits and state signs of psychosis risk captured by cognitive and perceptive basic symptoms

Objective

Schizotypal traits and disturbances in mentalizing (the capacity to understand the mental states driving one's own and others' behaviors) have been implicated in increased vulnerability for psychosis. Therefore, we explored the associations linking schizotypal traits, mentalizing difficulties and their interactions to clinical high-risk for psychosis (CHR-P), as captured by the Basic Symptoms (BS) approach, during adolescence and young adulthood.

Methods

Eighty-seven adolescents and young adults from the general population (46% male, 44% female; age: 14-23 years) were assessed with the Schizophrenia Proneness Interview (SPI-CY/A) for 11 perceptive and cognitive BS, with the Schizotypal Personality Questionnaire (SPQ) for schizotypal traits, and with the Reflective Functioning Questionnaire (RFQ) for self-reported mentalizing abilities. The RFQ evaluates the level of certainty (RFQc scale) and uncertainty (RFQu scale) with which individuals use mental state information to explain their own and others' behaviors.

Results

Logistic regression models showed significant positive effects of the SPQ disorganization scale on perceptive BS and of the SPQ interpersonal scale on cognitive BS. Post-hoc analyses revealed that schizotypal features pertaining to odd speech and social anxiety, respectively, were associated with perceptive and cognitive BS. Furthermore, higher scores on the RFQu scale and lower scores on the RFQc scale independently explained the presence of cognitive BS. Finally, significant interaction effects between RFQc and SPQ odd speech on perceptive BS, and between RFQc and SPQ social anxiety on cognitive BS were found.

Conclusion

Our findings suggest that schizotypal traits and mentalizing significantly relate both independently and through their interactions to the presence of cognitive and perceptive BS included in CHR-P criteria. Furthermore, mentalizing dysfunction may contribute in the relation between schizotypal traits and early state signs of CHR-P. Mentalizing may support both detection and early treatment of CHR-P among adolescents and young adults who present with trait risk for psychosis.

Attachment and resilience as mediators or moderators in the relationship between trauma and psychotic-like experiences

BACKGROUND

A large body of evidence has established a tight relation between traumatic experiences (TEs) and psychotic-like experiences (PLEs). Nevertheless, more comprehensive models involving multiple interactions of serial or parallel mediations and moderations still need to be elucidated. Among the many potential mediators or moderators, insecure attachment and resilience play a key role in the association of stress with PLEs. Hence, we aim to explore the complex pathways that lead from different types of TEs to PLEs, involving attachment and resilience modeled as mediators or moderators.

METHODS

One thousand ten high school students completed the International Trauma Exposure Measure (ITEM), the 11-item Resilience Scale for Adults (RSA-11), the 16-item Prodromal Questionnaire (iPQ-16), and the Relationship Questionnaire (RQ). A path analysis was conducted to assess mediation and moderation.

RESULTS

The final model showed that the impact of childhood TEs on PLEs was mediated by a pathway through anxious-insecure attachment styles (i.e., fearful and preoccupied, respectively, 8.75 % and 8.53 % of the total effect) and personal resilience resources. Conversely, the avoidant-insecure attachment was associated with lower interpersonal resilience (b = 0.14 [0.08, 0.20]), which in turn moderated the impact of recent TEs on PLEs (interaction term b = 0.34 [0.21, 0.47]).

CONCLUSIONS

Our model examines a complex model that includes factors buffering the effect of traumatic experiences on PLEs. Our results highlight the importance of insecure-anxious attachment to personal resilience resources and of insecure-avoidant attachment to interpersonal resilience as potential targets for clinical practice.

Mentalization based treatment of youth on the psychotic spectrum: clinical profiles and outcomes for youth in the ECID

Introduction

Early intervention may significantly improve the prognosis associated with psychotic disorders in adulthood.

Methods

The present study examined the acceptability and effectiveness of a standalone intensive, in-home, mentalization-based treatment (MBT) for extremely high-risk, non-help-seeking youth on the psychotic spectrum [Equipo Clínico de Intervención a Domicilio (ECID), Home Intervention Clinical Team].

Results

Despite previously being unable to participate in treatment, more than 90% of youth engaged and those on the psychotic spectrum demonstrated slightly higher engagement than the general high-risk group (95% and 85%, respectively, X₁ = 4.218, p = 0.049). Generalized estimating equation (GEE) models revealed no main group effect on the likelihood of reengaging with school over the first 12 months of treatment (X₁ = 1.015, p = 0.314) when controlling for the duration of school absenteeism at intake. Overall, the percentage of school engagement rose from 12 to 55 over this period, more than 40% of the total sample experienced clinically reliable change and an additional 50% appeared clinically stable. No statistically significant difference was observed between the groups in the average change in HoNOSCA total severity score (X₁ = 0.249, p = 0.618) or the distribution of youth into categories of clinical change during the first year of treatment (X₁ = 0.068, p = 0.795).

Discussion

The present findings suggest that a mentalization based intervention may be able to engage extremely high-risk youth in treatment and have clinically meaningful impact on symptom severity and functioning after 12 months.

A network analysis of anxiety, depressive, and psychotic symptoms and functioning in children and adolescents at clinical high risk for psychosis

Objective

Youths at clinical high risk for psychosis (CHR-P) are characterized by a high prevalence of anxiety and depressive disorders. The present study aimed at developing and analyzing a network structure of CHR-P symptom domains (i.e., positive, negative, disorganization, and general subclinical psychotic symptoms), depressive and anxiety symptoms, and general functioning.

Methods

Network analysis was applied to data on 111 CHR-P children and adolescents (M age = 14.1), who were assessed using the Structured Interview for Prodromal Syndromes, the Children's Depression Inventory, the Children's Global Assessment Scale, and the Multidimensional Anxiety Scale for Children.

Results

In the network, negative and disorganization symptoms showed the strongest association (r = 0.71), and depressive and anxiety symptoms showed dense within-domain connections, with a main bridging role played by physical symptoms of anxiety. The positive symptom cluster was not associated with any other node. The network stability coefficient (CS) was slightly below 0.25, and observed correlations observed ranged from 0.35 to 0.71.

Conclusion

The lack of association between subclinical positive symptoms and other network variables confirmed the independent nature of subclinical positive symptoms from comorbid symptoms, which were found to play a central role in the analyzed network. Complex interventions should be developed to target positive and comorbid symptoms, prioritizing those with the most significant impact on functioning and the most relevance for the young individual, through a shared decision-making process. Importantly, the results suggest that negative and disorganization symptoms, as well as depressive and anxiety symptoms, may be targeted simultaneously.

Mentalizing in first-episode psychosis: Correlates with symptomatology and traits of borderline personality disorder

AIM

To explore the associations between mentalizing, positive and negative symptoms of psychosis, and traits of borderline personality disorder, in a sample of patients with first-episode psychosis, and in a non-clinical sample.

METHODS

A quantitative cross-sectional design was employed. Thirty-two adults with first-episode psychosis and 148 non-clinical participants were assessed using the reflective functioning questionnaire. The questionnaire measures two dimensions of mentalizing, certainty and uncertainty about mental states. Traits of borderline personality disorder and symptoms of psychosis were measured using the self-report version of the Zanarini rating scale, the Community Assessment of Psychotic Experiences, and the Green et al., paranoid thought scale.

RESULTS

Patients with first-episode psychosis reported increased mentalizing impairments, characterized as hypomentalizing tendencies, compared to the non-clinical group. Regression analysis showed significant associations between higher scores on the uncertainty about mental states scale and negative symptoms of psychosis in both groups. No associations were found between mentalizing impairments and traits of borderline personality disorder in the clinical sample, although associations were found in the non-clinical sample.

CONCLUSIONS

The present findings suggests that impairments in mentalizing may be associated with negative symptoms of psychosis across both clinical and non-clinical samples. Mentalizing impairments was found to be associated with traits of borderline personality disorder, but this finding was only confirmed in the non-clinical sample. Mentalizing should therefore be considered in the early assessment and treatment of patients experiencing difficulties with negative symptoms of psychosis.

Centrality and Decentration: A Model for Understanding Disturbances in the Relationship of the Self to the World in Psychosis

ABSTRACT

A considerable body of phenomenological research has described different ways in which the relationship of the person to the world in psychosis is affected. This literature, however, has lacked an accepted unifying theoretical model and means of quantitatively measuring these disturbances. To address this, the current article seeks to integrate a novel phenomenological model of psychosis offered by Henri Grivois, which is explicitly concerned with centrality or a person's sense of being the center of all things, with empirical research on the integrative model of metacognition, which allows for measurements of decentration or the degree to which persons can form integrated ideas about their place in their larger community. It is proposed that this literature may allow for a model of how psychotherapy can address centrality through the building of intersubjectivity and enhancing metacognition.

Affective temperaments and depressive symptoms: The mediating role of attachment

BACKGROUND

Studies showed that affective temperaments and attachment are associated with depressive symptoms, and that they bi-directionally influence each-other. The aim of this study is to explore mechanisms underlying the relationship between the affective temperaments (i.e., depressive, cyclothymic, irritable, hyperthymic and anxious), interview-based attachment, and depressive symptoms.

METHODS

A sample of 61 adolescents and young adults outpatients were asked to complete the Temperament Evaluation of Memphis, Pisa, and San Diego Autoquestionnaire (TEMPS-A) and the Hamilton Rating Scale for Depression (HAM-D). Attachment was assessed through the Adult Attachment Interview (AAI) and employing a dimensional approach to obtain continuous measures. Mediation models were performed with the affective temperaments as predictor, depressive symptoms as the criterion variable, and attachment dimensions as mediators.

RESULTS

Findings showed significant direct effects between all the affective temperaments and depressive symptoms. Only the cyclothymic (β = 0.22; SE = 0.1; 95% IC = 0.05, 0.42) and irritable (β = 0.21; SE = 0.09; 95% IC = 0.04, 0.4) temperaments showed an indirect effect on depressive symptoms through secure-insecure attachment. Dismissing attachment did not predict either the affective temperaments nor depressive symptoms. Preoccupied attachment significantly predicts depressive symptoms and, when controlling for it, the hyperthymic temperament no longer directly associates with depressive symptoms.

LIMITATIONS

The cross-sectional study design limit conclusion about causation and directionality.

CONCLUSIONS

Secure attachment could be a protective factor for depressive symptoms for individuals with a cyclothymic or irritable temperament. Differently, the hyperthymic temperament loses its protective role toward depressive symptoms when accounting for preoccupied attachment.

Metacognition, social cognition, and mentalizing in psychosis: are these distinct constructs when it comes to subjective experience or are we just splitting hairs?

Research using the integrated model of metacognition has suggested that the construct of metacognition could quantify the spectrum of activities that, if impaired, might cause many of the subjective disturbances found in psychosis. Research on social cognition and mentalizing in psychosis, however, has also pointed to underlying deficits in how persons make sense of their experience of themselves and others. To explore the question of whether metacognitive research in psychosis offers unique insight in the midst of these other two emerging fields, we have offered a review of the constructs and research from each field. Following that summary, we discuss ways in which research on metacognition may be distinguished from research on social cognition and mentalizing in three broad categories: (1) experimental procedures, (2) theoretical advances, and (3) clinical applications or indicated interventions. In terms of its research methods, we will describe how metacognition makes a unique contribution to understanding disturbances in how persons make sense of and interpret their own experiences within the flow of life. We will next discuss how metacognitive research in psychosis uniquely describes an architecture which when compromised - as often occurs in psychosis - results in the loss of persons' sense of purpose, possibilities, place in the world and cohesiveness of self. Turning to clinical issues, we explore how metacognitive research offers an operational model of the architecture which if repaired or restored should promote the recovery of a coherent sense of self and others in psychosis. Finally, we discuss the concrete implications of this for recovery-oriented treatment for psychosis as well as the need for further research on the commonalities of these approaches.

Construct Validity of the Mentalization Scale (MentS) Within a Mixed Psychiatric Sample

Introduction: The concept of mentalizing is nowadays widely used in research as well as in clinical practice. Despite its popularity, the development of an economic assessment is still challenging. The Mentalization Scale appears to be a promising measurement with good psychometric properties but lacking convergent validity with the Reflective Functioning Scale. Objective: This study aims to test the construct validity of the Mentalization Scale through correlations with the gold standard, the Reflective Functioning Scale, within a clinical sample. Furthermore, it was of interest to replicate its internal consistency. Methods: Twenty-six inpatients of an acute psychiatric ward in Vienna were given the Mentalization Scale (MentS). They were interviewed with the Brief Reflective Function Interview, which was coded with the Reflective Functioning Scale. Correlations and internal consistency were calculated. Results: Concerning the primary aim of this study, the validity was satisfactory for the MentS whole-scale mentalizing as well as for the subscales self- and other-oriented mentalizing. Internal consistency was lower to the findings of the developer and close to the 0.70 threshold. Conclusion: Our findings could foster the psychometric properties of the MentS. Furthermore, the MentS seems to be a promising measurement tool for detecting different dimensions of reflective functioning. Limitations and further research are discussed.

Machine learning-based ability to classify psychosis and early stages of disease through parenting and attachment-related variables is associated with social cognition

Background

Recent views posited that negative parenting and attachment insecurity can be considered as general environmental factors of vulnerability for psychosis, specifically for individuals diagnosed with psychosis (PSY). Furthermore, evidence highlighted a tight relationship between attachment style and social cognition abilities, a key PSY behavioral phenotype. The aim of this study is to generate a machine learning algorithm based on the perceived quality of parenting and attachment style-related features to discriminate between PSY and healthy controls (HC) and to investigate its ability to track PSY early stages and risk conditions, as well as its association with social cognition performance.

Methods

Perceived maternal and paternal parenting, as well as attachment anxiety and avoidance scores, were trained to separate 71 HC from 34 PSY (20 individuals diagnosed with schizophrenia + 14 diagnosed with bipolar disorder with psychotic manifestations) using support vector classification and repeated nested cross-validation. We then validated this model on independent datasets including individuals at the early stages of disease (ESD, i.e. first episode of psychosis or depression, or at-risk mental state for psychosis) and with familial high risk for PSY (FHR, i.e. having a first-degree relative suffering from psychosis). Then, we performed factorial analyses to test the group x classification rate interaction on emotion perception, social inference and managing of emotions abilities.

Results

The perceived parenting and attachment-based machine learning model discriminated PSY from HC with a Balanced Accuracy (BAC) of 72.2%. Slightly lower classification performance was measured in the ESD sample (HC-ESD BAC = 63.5%), while the model could not discriminate between FHR and HC (BAC = 44.2%). We observed a significant group x classification interaction in PSY and HC from the discovery sample on emotion perception and on the ability to manage emotions (both p = 0.02). The interaction on managing of emotion abilities was replicated in the ESD and HC validation sample (p = 0.03).

Conclusion

Our results suggest that parenting and attachment-related variables bear significant classification power when applied to both PSY and its early stages and are associated with variability in emotion processing. These variables could therefore be useful in psychosis early recognition programs aimed at softening the psychosis-associated disability.

Reflective Functioning in Patients with Irritable Bowel Syndrome, Non-Affective Psychosis and Affective Disorders-Differences and Similarities

Irritable bowel syndrome (IBS), as part of the functional somatic syndromes, is frequent in the general population. Medical care and morbidity costs are high, and so is the psychological and somatic strain. The etiopathogenesis of IBS is still poorly understood; it is assumed to be multifactorial and to include biopsychosocial factors. Links between the intestine, psyche, nervous system (e.g., via the hypothalamic-pituitary-adrenal axis (HPA-Axis/neurotransmitters) and with the microbiome, the immune system have lately been investigated. Factors such as personality traits, mentalization, and early attachment strategies (deactivating and hyperactivating) have been suggested to influence IBS with relevance for treatment regimens. At this time, data on reflective functioning (RF) is lacking. Within a cross-sectional, we examined the mentalizing capacity of a clinical sample (n = 90) consisting of patients with IBS (n = 30), affective disorders (AD; n = 28), and non-affective psychosis (NAP; n = 32). The reflective functioning scale was used based on the brief reflective function interview (BRFI). The results revealed severe impairment in patients with IBS concerning their mentalizing ability, which was comparable to patients with affective disorders. Patients with non-affective-psychosis showed the lowest mentalizing ability. Thus, psychotherapeutic treatment with a focus on mentalization could be a promising approach.

Personality Traits and Disorders in Adolescents at Clinical High Risk for Psychosis: Toward a Clinically Meaningful Diagnosis

Aims: Recent meta-analytic data show that approximately 40% of individuals at clinical high risk for psychosis (CHR) receive at least one personality disorder (PD) diagnosis. Personality pathology could significantly influence CHR patients' prognosis and response to treatment. We aimed at exploring the PD traits of CHR adolescents, in order to outline a prototypic description of their most frequently observed personality characteristics. Methods: One hundred and twenty-three psychiatrists and psychologists used a Q-sort procedure [i.e., the Shedler-Westen Assessment Procedure-200 for Adolescents (SWAP-200-A)] to assess personality traits and disorders in 58 (30 male; mean age = 16 years, range = 13-19 years) CHR adolescents and two gender- and age-matched samples, respectively, with (n = 60) and without PDs (n = 59). Results: Differences between the CHR, PD, and clinical groups showed that CHR adolescents had pervasive and more clinically relevant schizoid, schizotypal, borderline, and avoidant traits, as well as poorer adaptive functioning. Moreover, by collecting the highest mean SWAP-200-A items, we empirically outlined a prototypic description of CHR youths, comprised of avoidance of social relationships; suspiciousness; obsessional thoughts; lack of psychological insight; dysphoric and overwhelming feelings of anxiety and depression; odd and anomalous reasoning processes or perceptual experiences; symptoms of depersonalization and derealization; and negative symptoms of avolition, abulia, blunted affects, and impaired role functioning. Conclusions: The results suggest that avoidant interpersonal strategies, impaired mentalization, and difficulties in emotional regulation could become important targets for psychosocial interventions with CHR adolescent populations.
