Prolonged confinement in cramped spaces can lead to derangements in brain function/structure, yet the underlying mechanisms remain unclear. To investigate, we subjected mice to restraint stress to simulate long-term narrow and enclosed space confinement, assessing their mental state through behavioral tests. Stressed mice showed reduced center travel and dwell time in the Open Field Test and increased immobility in the Tail Suspension Test. We measured lower hippocampal brain-derived neurotrophic factor levels and cortical monoamine neurotransmitters (5-HT and NE) in the stressed group. Further examination of the body's immune levels and serum metabolism revealed immune dysregulation and metabolic imbalance in the stressed group. The results of the metabolic network regulation analysis indicate that the targets affected by these differential metabolites are involved in several metabolic pathways that the metabolites themselves participate in, such as the "long-term depression" and "purine metabolism" pathways. Additionally, these targets are also associated with numerous immune-related pathways, such as the TNF, NF-κB, and IL-17 signaling pathways, and these findings were validated using GEO dataset analysis. Molecular docking results suggest that differential metabolites may regulate specific immune factors such as TNF-α, IL-1β, and IL-6, and these results were confirmed in experiments. Our research findings suggest that long-term exposure to confined and narrow spaces can lead to the development of psychopathologies, possibly mediated by immune system dysregulation and metabolic disruption.

BACKGROUND
Personal recovery is operationalized in the CHIME framework (connectedness, hope, identity, meaning in life, and empowerment) of recovery processes. CHIME was initially developed through analysis of experiences of people mainly with psychosis, but it might also be valid for investigating recovery in mood-related, autism and other diagnoses.
AIMS
To examine whether personal recovery is transdiagnostic by studying narrative experiences in several diagnostic groups.
METHODS
Thirty recovery narratives, retrieved from "Psychiatry Story Bank" (PSB) in the Netherlands, were analyzed by three coders using CHIME as a deductive framework. New codes were assigned using an inductive approach and member checks were performed after consensus was reached.
RESULTS
All five CHIME dimensions were richly reported in the narratives, independent of diagnosis. Seven new domains were identified, such as "acknowledgement by diagnosis" and "gaining self-insight". These new domains were evaluated to fit well as subdomains within the original CHIME framework. On average, 54.2% of all narrative content was classified as experienced difficulties.
CONCLUSIONS
Recovery stories from different diagnostic perspectives fit well into the CHIME framework, implying that personal recovery is a transdiagnostic concept. Difficulties should not be ignored in the context of personal recovery based on its substantial presence in the recovery narratives.

OBJECTIVE
The present paper focuses on therapist responsiveness during the initial therapy session with clients with borderline personality disorder (BPD), aiming to analyze therapist responsiveness at short intervals during the initial session and determine if it can predict therapeutic alliance from both therapist and client viewpoints.
METHOD
A sample of 47 clients participated in the study for 10 sessions of therapy. Therapeutic alliance from therapists' and clients' perspectives was rated after each session; external raters assessed therapist responsiveness during the initial session. Multiple linear regression models and linear mixed models with backward variable selection based on AIC were run to analyze whether specific therapist behaviors during session one predicted therapeutic alliance rated from therapists' and clients' perspectives.
RESULTS
The results indicate that therapists normalizing and validating clients' experiences during the first session are crucial for establishing therapeutic alliance for BPD clients; however, for therapists, the increase in variability of emotions verbalized by clients during the initial session negatively impacts therapeutic alliance.
CONCLUSION
The study contributes to further understand the impact of therapists' behavior at the beginning of therapy with BPD clients. Therapist responsiveness is crucial for therapy outcome but is methodologically challenging; therefore, efforts in this direction should be pursued.

BACKGROUND
Health professionals from different specialties in medical and psychological areas play an important role in diagnosis and treatment of eating disorders (EDs). This study aimed to identify gaps in knowledge about the diagnosis, etiology, and management of EDs and to assess health professionals' attitudes towards these illnesses.
METHODS
A new questionnaire was developed and validated. Residents and consultants working in disciplines involved in the management of EDs (namely, internal medicine, general practitioners, psychiatric area, psychological area, and surgical area) completed the questionnaire. Knowledge and attitudes were compared among the study groups through one-way ANCOVA and chi-square tests.
RESULTS
The final version of the questionnaire consisted of 54 items assessing the following areas: stigma, treatment, physical complications, diagnosis, and aetiopathogenesis of EDs. For all health professionals the area of most deficiency was the aetiopathogenesis, while the best one was the management of physical complications. All medical professionals showed less knowledge than psychiatrists in terms of etiology, diagnosis, and treatment of EDs. A lack of knowledge about evidence-based psychotherapies, general psychopathology, and family members' role in the management of EDs emerged among all health professionals. Stigma was found among non-mental health professionals who considered these patients to be different from others and responsible for their abnormal eating behaviors.
CONCLUSIONS
Clarifying the health professionals' specific gaps occurring in the knowledge of EDs and in the attitudes towards these individuals may inform educational programs to improve early detection and management of EDs.

This study examined the association of clinical factors, independent of sex and high psychosocial adversity (HPAd), with the presence of ADHD or other mental disorders, specifically within a middle-income country with a non-Caucasian population. A multi-centric cross-sectional study was conducted in three sites in Colombia. Our study recruited trios of an ADHD proband, one sibling, and one parent. We used valid instruments for assessing parents and siblings. The sample included 223 siblings, an average age of 12.3 (SD 3.9), and 51.1% Females. The ADHD recurrence risk ratio (λ) was 12. The clinical factors mainly associated with the presence of ADHD, independent of sex and HPAd, were 1) Pregnancy and childbirth complications, 2) Delayed psychomotor development, 3) Temperament, and 4) Sleep disturbances. Our research showed that, independently of HPAd and the male sex, there were other clinical factors associated with ADHD and other psychiatric disorders in this population. These findings need to be replicated in similar populations globally.

Self-dehumanization, a phenomenon relevant to social psychology, has been somewhat absent from clinical psychology research. Furthermore, measures of self-dehumanization are few, and to our knowledge, no validated and generalizable self-report measure exists. To address this gap, we present a Self-Dehumanization Scale (SDS). This work incorporates evidence from three studies examining the reliability, validity, and factor structure of the SDS in an undergraduate sample, a clinically relevant community sample, and a sample with at least one minoritized identity. The SDS was derived from dehumanization theory and was developed to measure animalistic and mechanistic self-dehumanization. All studies suggested an 8-item SDS, with Study 1 suggesting a single-factor solution with, however, some indication of a two-factor structure, and Studies 2 and 3 affirming a two-factor solution. The SDS, and its respective factors, generally showed discriminant validity from related, yet distinct, measures of self-hate, self-esteem (Study 2), dissociation, and measures of discrimination (in Study 3). Finally, animalistic and mechanistic SDS showed somewhat mixed but promising evidence regarding their associations to minoritized identities and to symptoms of depression, and suicide risk, above and beyond each study's fairly stringent control variables. Thus, self-dehumanization may prove to be a clinically promising leverage point in assessing psychopathology, particularly among minoritized communities.

To improve outcomes for youth who do not respond optimally to existing treatments, we need to identify robust predictors, moderators, and mediators that are ideal targets for personalisation in mental health care. We propose a solution to leverage the Individual Patient Data Meta-analysis (IPDMA) approach to allow broader access to individual-level data while maintaining methodological rigour. Such a resource has the potential to answer questions that are unable to be addressed by single studies, reduce researcher burden, and enable the application of newer statistical techniques, all to provide data-driven strategies for clinical decision-making. Using childhood anxiety as the worked example, the editorial perspective outlines the rationale for leveraging IPDMA methodology to build a data repository, the Platform for Anxiety Disorder Data in Youth. We also include recommendations to address the methods and challenges inherent in this endeavour.

High stress in parents may affect parenting and subsequent child socioemotional and behavioral development. Previous evidence suggests that highly stressed parents are more likely to engage in negative parenting, which is less structured and more punitive. However, the effects of life stress versus parent specific stress on parent-child interactions in early childhood has not been well studied, especially in minority and low-income samples. Thus, the current study assessed the relationship between perceived life stress, parenting-related stress, and observed parenting responses to young children during a structured, mildly challenging parent-child task. Predominantly minority and low-income parents and their children (2-5 years old; 54 dyads) completed the Perceived Stress Scale, the Parenting Stress Inventory, and participated in a structured 5-minute interaction task, the Toy-Wait Task (TWT), that was video-taped and coded by blind raters. The coding utilized a standardized system with good reliability assessing 1) Affect (parent and child positive and negative affect, shared positive affect), 2) Positive Parenting Behaviors (warmth, structured good involvement, listening/engagement), and 3) Negative Parenting Behaviors (reactivity, judgment, critical parenting). Significant associations were found between perceived life stress and parenting stress, (r (54) = 0.61, p<.01). Parents with higher perceived life stress scores showed more negative affect (r=0.291, p<.05) and lower involvement with the child (r=-0.367, p<.05), while parenting specific stress did not yield significant effects (p's > 0.05). Findings suggest that interventions that reduce stress in minority and low-income parents of young children may also improve parenting of young children with potential impact on decreasing child psychopathology risk.

BACKGROUND
In schizophrenia patients, spontaneous speech production has been hypothesized as correlating with right hemispheric activation, including the inferior frontal and superior temporal gyri as speech-relevant areas. However, robust evidence for this association is still missing. The aim of the present fMRI study is to examine BOLD signal changes during natural, fluent speech production in patients with schizophrenia in the chronic phase of their disease.
METHODS
Using a case-control design, the study included 15 right-handed patients with schizophrenia spectrum disorders as well as 15 healthy controls. The participants described eight pictures from the Thematic Apperception Test for 1 min each, while BOLD signal changes were measured with 3T fMRI. The occurrence of positive and negative formal thought disorders was determined using standardized psychopathological assessments.
RESULTS
We found significant BOLD signal changes during spontaneous speech production in schizophrenia patients compared to healthy controls, particularly in the right hemispheric network. A analysis showed that this right-hemispheric lateralization was mainly driven by activation during experimental rests. Furthermore, the TLI sum value in patients correlated negatively with BOLD signal changes in the right Rolandic operculum.
CONCLUSIONS
Possible underlying factors for this inverse right-hemispheric lateralization of speech-associated areas are structural changes and transmitter system alterations, as well as a lack of neural downregulation in schizophrenia patients during rest periods due to dysfunctional executive functions. When examining spontaneous speech as the most natural form of language, other influencing factors, such as social cognition or emotional processing, should be considered. Our results indicate that future studies should consider group differences during rest, which might provide additional information typically covered in differential contrasts.

BACKGROUND
Individuals with anxiety disorders (ADs) often display hypervigilance to threat information, although this response may be less pronounced following psychotherapy. This study aims to investigate the unconscious recognition performance of facial expressions in patients with panic disorder (PD) post-treatment, shedding light on alterations in their emotional processing biases.
METHODS
Patients with PD (n=34) after (exposure-based) cognitive behavior therapy and healthy controls (n=43) performed a subliminal affective recognition task. Emotional facial expressions (fearful, happy, or mirrored) were displayed for 33 ms and backwardly masked by a neutral face. Participants completed a forced choice task to discriminate the briefly presented facial stimulus and an uncovered condition where only the neutral mask was shown. We conducted a secondary analysis to compare groups based on their four possible response types under the four stimulus conditions and examined the correlation of the false alarm rate for fear responses to non-fearful (happy, mirrored, and uncovered) stimuli with clinical anxiety symptoms.
RESULTS
The patient group showed a unique selection pattern in response to happy expressions, with significantly more correct "happy" responses compared to controls. Additionally, lower severity of anxiety symptoms after psychotherapy was associated with a decreased false fear response rate with non-threat presentations.
CONCLUSION
These data suggest that patients with PD exhibited a "happy-face recognition advantage" after psychotherapy. Less symptoms after treatment were related to a reduced fear bias. Thus, a differential facial emotion detection task could be a suitable tool to monitor response patterns and biases in individuals with ADs in the context of psychotherapy.
