Summary: Using a cluster analytic approach, this study identified two distinct subgroups of social anxiety disorder (SAD) based on temperament characteristics. The prototypic subtype of SAD showed higher levels of harm avoidance and lower novelty seeking, while the atypic subtype exhibited medium to high harm avoidance and increased novelty seeking. These subgroups differed in various sociodemographic and clinical variables.

Summary: Bedtime procrastination may be an adaptive fast LH strategy, and personal beliefs about abilities and resources promote this behavior. The study found that harm avoidance partially mediates the relationship between self-efficacy and bedtime procrastination, and novelty seeking acts as a moderator.

Summary: Research showed that patients with nightmares often do not receive sufficient treatment. This is partly because nightmare sufferers themselves often do not seek professional help or find it unhelpful. This study aimed to investigate trait factors (personality, harm avoidance) in relation to considering seeking professional help. In a population sample, it was found that only some nightmare sufferers considered seeking professional help, and high harm avoidance and introversion were associated with not seeking help. Low education, low agreeableness, and low conscientiousness were also linked to considering seeking professional help, possibly due to fear of stigmatization. Future efforts should focus on discovering new ways to provide effective help for nightmares and increasing healthcare professionals' understanding of nightmare treatment.

Summary: This systematic review found that neuroticism is the most widely studied personality trait in relation to postpartum depression (PPD). The meta-analysis showed a strong relationship between neuroticism and PPD, while vulnerable personality style and trait anxiety were also associated with PPD. Screening for these traits could help identify women at risk, improving early detection and potentially treatment.

Summary: The study demonstrates that adherence to containment measures during the pandemic is influenced by personality traits and moral dispositions. Personality traits such as novelty-seeking, harm-avoidance, and authority concerns play a role in driving compliance with lockdown measures, while moral foundation assessments can help policymakers understand and predict public compliance.

Summary: This study found that individuals with obesity and type 2 diabetes have poorer decision-making abilities compared to healthy individuals, while those with only obesity exhibit lower cognitive flexibility and higher harm avoidance. These results suggest a stronger link between impulsivity and obesity with diabetes than with obesity alone.

Summary: The study investigated whether baseline individual characteristics of male C57BL/6J mice could predict the resilient outcome after chronic social defeat (CSD). The results showed significant differences in exploration levels, approach to novelty, and avoidance of harm between resilient and susceptible mice. Before the stress, resilient mice demonstrated higher exploratory drive and approach to novel environments, while susceptible mice showed better performance in avoiding potential adversity.

Summary: In this study, fear and anxiety are examined in the context of personality and psychopathology models, along with their assessment. Anxiety is a sustained, future-oriented response to potential threat, while fear is a brief, present-focused response to acute threat. Assessing individual differences in fear can be done through phobic responses to specific stimuli or through differentiating between harm avoidance and risk taking. These measures are correlated with various personality traits and factors within psychopathology models.

Summary: In the past 25 years, since the conceptualization of ultra-high-risk (UHR) states for psychosis, empirical evidence in the field has been constantly reviewed and re-assessed through meta-analysis. The scrutiny focuses on three major evidences: pretest risk enrichment, risk hierarchy within UHR states, and declining transition rates. However, the dilution effect remains elusive and may be symptomatic of unresolved issues in the field.

Summary: The strategic value of early, preventive intervention in psychosis has led to the recognition of the clinical high risk states for psychosis (CHR) as a key factor for timely risk inception. This study found that CHR in adolescents have comparable transition prevalences to those found in adults, highlighting the relevance of CHR criteria.

Summary: This study aimed to investigate the stability of aberrant salience (AS) in early stages of psychosis in an Italian population of help-seeking adolescents, and to examine its association with specific treatment components of an early intervention program. The study found that after 1 year of follow-up, both first episode psychosis (FEP) patients and those at ultra-high risk (UHR) of psychosis showed a significant reduction in AS levels, which was correlated with specific treatment components such as psychoeducational sessions and individual cognitive-behavioral therapy sessions.

Summary: In this paper, we study the space of linear cocycles over a hyperbolic homeomorphism on a compact metric space. We prove that locally near any typical cocycle, the Lyapunov exponents are Holder continuous functions relative to the uniform topology. Furthermore, we establish other statistical properties for the iterates of such cocycles, including a central limit theorem and a large deviations principle, as a result of our approach based on a uniform large deviations type estimate in the space of cocycles.

Summary: This study reviewed the literature on sensory phenomena and neurodevelopmental antecedents in obsessive compulsive disorder (OCD) to propose a bottom-up perspective for understanding OCD. The findings indicate that sensory phenomena and neurodevelopmental features are associated with OCD. The study suggests a neurodevelopmental-phenomenological model that can explain the dimensional affinity between OCD and schizophrenia spectrum disorders.

Summary: This study aimed to investigate the symptom severity and prognosis of individuals at clinical high-risk for psychosis who were on antipsychotic medication during a 1-year follow-up period. The results showed that compared to those not taking antipsychotics, individuals on antipsychotic medication had more severe symptoms and lower functioning at baseline. At the end of the follow-up period, individuals on antipsychotic medication had higher rates of psychosis transition, hospitalizations, and urgent/non-planned visits.

Summary: This research aimed to examine the relationship between anhedonia and suicidal thoughts in individuals with First Episode Psychosis (FEP) and at Ultra High Risk (UHR) of psychosis. The study found that an enduring and independent association between anhedonia and suicidal ideation existed in FEP individuals, while in the UHR subgroup, the relationship between anhedonia and suicidal thoughts was not completely independent from depression severity.

Summary: Meta-analytic evidence shows that baseline exposure to antipsychotics is associated with a higher risk of transition to psychosis in individuals at clinical high-risk for psychosis. This study aimed to clarify the temporal dynamics of this prognostic effect. Through a systematic review and meta-analysis, it was found that baseline AP-exposed CHR-P had a higher risk of transition at specific time points, supporting the need for stricter clinical monitoring. However, the lack of detailed information in the primary literature limited the testing of causal hypotheses on this association.

Summary: We report a pathological imagination process in an adolescent at clinical high-risk for psychosis, associated with the presence of self-disorders. The subjective experience associated with pathological imagination helps distinguish it from intrusive thoughts in obsessive-compulsive patients; moreover, such anomalous imagination focused on others may be an adaptive process triggered by negative emotionality towards others who are difficult to relate to. In conclusion, anomalies of imaginations may occur within the schizophrenic spectrum during adolescent prodromal stages, associated with self-disorders.
