Introduction: Reported rates of non-suicidal self-injury (NSSI) differ by gender but may be under-reported and under-recognised in men. People engaging in NSSI rarely seek professional help without encouragement, so others play a key role in its identification and potential intervention. The current research investigated others' interpretations of NSSI, examining whether gender affects the likelihood of NSSI identification and views of how common and acceptable NSSI is.

Method: Participants (N = 429; 74.1% female, 23.3% male; please see below for further demographic information) responded to two vignettes describing a person self-injuring by punching a wall or by cutting themselves. The person's gender in each vignette was manipulated. Following each vignette, the participants rated the level to which they agreed the behaviour was common for the gender of the person described, as well as the level to which they agreed the behaviour was acceptable for the gender of the person described, on a 5-point Likert scale. Following both vignettes, participants were presented with a definition of NSSI and rated the level to which they agreed cutting and wall-punching were forms of NSSI on 5-point Likert scales. Independent-samples t tests and goodness of fit χ2 tests were conducted as appropriate.

Results: Participants were more likely to identify wall-punching as common for men and cutting as common for women. However, there was no significant difference in whether wall-punching was identified as NSSI or considered to be an acceptable behaviour, regardless of the gender of the person engaging in it. That is, although research suggests that men are far more likely to engage in wall-punching as a form of NSSI than women, participants did not recognise this. Overall, the results indicated a gender-dependent difference in how acceptable and common NSSI is thought to be, but no noticeable difference in identification of a behaviour as NSSI. Wall-punching, typically a form of NSSI engaged in by males, tended not to be identified as such.

Conclusion: There is an effect of gender on how NSSI is interpreted, and it seems that men's NSSI is, and will continue to be, under-recognised. This has important implications for the treatment of men's NSSI, which is more likely to be seen as aggression and therefore deserving of punishment than an attempt at emotion regulation.

Introduction: Adolescents with major depressive disorder (MDD) exhibit hypoactivity to positive stimuli and hyperactivity to negative stimuli in terms of neural responses. Automatic emotion regulation (AER) activates triple networks (i.e., the central control network, default mode network, and salience network). Based on previous studies, we hypothesized that adolescents with MDD exhibit dissociable spatiotemporal deficits during positive and negative AER.

Methods: We first collected EEG data from 32 adolescents with MDD and 35 healthy adolescents while they performed an implicit emotional Go/NoGo task. Then, we characterized the spatiotemporal dynamics of cortical activity during AER.

Results: In Go trials, MDD adolescents exhibited reduced N2 amplitudes, enhanced theta power for positive pictures, and stronger bottom-up information flow from the left orbitofrontal cortex (OFC) to the right superior frontal gyrus compared to top-down information flow than the controls. In contrast, in NoGo trials, MDD adolescents exhibited elevated P3 amplitudes, enhanced theta power, and stronger top-down information flows from the right middle frontal gyrus to the right OFC and the left insula than the controls.

Conclusion: Overall, adolescents with MDD exhibited impaired automatic attention to positive emotions and impaired automatic response inhibition. These findings have potential implications for the clinical treatment of adolescents with MDD.

Negative symptoms reflect a currently much-untreated loss of normal functioning and are frequently found in psychotic disorders. We present the first translation of the Brief Negative Symptom Scale (BNSS) to European Portuguese and evaluate its validity in a sample of Portuguese male patients with a psychotic spectrum disorder. The Portuguese BNSS showed excellent internal consistency, high convergent validity (i.e., strong correlation with the PANSS negative factor), and high discriminant validity (i.e., a lack of association with the PANSS positive factor). In sum, the present European Portuguese BNSS has shown to be reliable, thus extending this instrument's clinical availability worldwide.

Objective: This study aimed to investigate the influence of familial predisposition on substance-induced psychosis among healthy siblings of patients diagnosed with substance-induced psychotic disorder, who themselves lack any family history of psychotic disorders. Additionally, the study aimed to explore clinical high-risk states for psychosis, schizotypal features, and neurocognitive functions in comparison to a healthy control group.

Method: The study compared healthy siblings of 41 patients diagnosed with substance-induced psychotic disorder with 41 healthy volunteers without a family history of psychotic disorders, matching age, gender, and education. Sociodemographic and clinical characteristics of participants were obtained using data collection forms. The Comprehensive Assessment of At-Risk Mental States (CAARMS) and the Structured Interview for Schizotypy-Revised Form (SIS-R) scales were utilized to assess clinical high risk for psychosis. Neurocognitive functions were evaluated with digit span test (DST), trail making test part A-B (TMT), verbal fluency test (VFT), and Stroop test (ST).

Results: Analysis using the CAARMS scale revealed that 39% of siblings and 7.3% of the control group were at clinically high risk for psychosis, indicating a significant difference in rates of psychotic vulnerability. Comparison between siblings and the control group showed significant differences in mean SIS-R subscale scores, including social behavior, hypersensitivity, referential thinking, suspiciousness, illusions, and overall oddness, as well as in mean neurocognitive function scores, including errors in TMT-A, TMT-B, and VFT out-of-category errors, with siblings exhibiting poorer performance.

Conclusion: Our study suggests that healthy siblings of patients with substance-induced psychosis exhibit more schizotypal features and have a higher risk of developing psychosis compared to healthy controls. Additionally, siblings demonstrate greater impairment in attention, response inhibition, and executive functions compared to healthy controls, indicating the potential role of genetic predisposition in the development of substance-induced psychotic disorder.

Introduction: Recently, acceptance- and commitment therapy (ACT) gained increasing interest. Studies show good efficacy in the treatment of patients presenting with several psychologic and somatic complaints. The present systematic review and meta-analysis addresses effectiveness of ACT-based interventions to reduce stress in children, adolescents, and young adults compared to control conditions.

Methods: The meta-analysis was pre-registered at PROSPERO (CRD42019117440). Randomized controlled trials (RCTs) and quasi-randomized controlled trials (qRCT) in German or English language comparing the effects of ACT-based interventions to control conditions (e.g., treatment as usual, waitlist control) on stress-related outcome measures in youth were considered for inclusion. The target population was subjects 0-18 years of age. The databases PubMed, PsychInfo, Cochrane Database, CINAHL, and Web of Science were searched systematically up to July 2023. A random effect meta-analysis and a risk of bias assessment according to the procedure outlined in the Cochrane Handbook of Systematic Reviews were conducted.

Results: The search resulted in 187 studies, of which eight studies with 976 participants were finally subjected to meta-analysis. Studies implemented ACT both in school-based group settings and in single settings and both as a universal and indicated prevention. Analyses yielded a significant main effect (Hedges' g = -0.20; 95% confidence interval [-0.36; -0.05]), indicating that interventions based on ACT resulted in greater reduction of stress compared to control conditions.

Conclusion: ACT appears effective at reducing stress in youth. Further research is needed due to methodological shortcomings of existing studies. Small sample sizes, heterogenous studies, methodological shortcomings, and evidence of publication bias limit the conclusions that can be drawn from this meta-analysis.

Background: Spiritual, metaphysical, or eschatological elements in delusions (SMEDs) are frequent and often subjectively regarded as profound transformational experiences, similar to mystical experiences. This study aimed (1) to explore how SMEDs are experienced and in which aspects they are similar to mystical experiences and (2) to investigate how individuals make sense of SMED.

Methods: Seven participants were interviewed, and their expressions were analyzed using interpretative phenomenological analysis.

Results: We found that SMEDs were similar to mystical experiences with regard to alterations in perception of space, time, and unity. Furthermore, SMEDs were accompanied by a sense of enlightenment that however remained ineffable. SMEDs were interpreted from different viewpoints, i.e., as a source of ontological insight, as a mental health issue, as an inspiration for a new orientation in the world, and, for some participants, as an example of the limits of knowledge. Making sense of SMED appeared to follow a lively internal dialogue in which various, sometimes contradictory positions were reflected upon. Participants usually struggled to align the ostensible ontological significance of SMED to the dominating illness explanation.

Conclusion: SMEDs have similarities to mystical experiences, but integrating SMED into one's own life is challenging. We propose a philosophical, non-pathological interpretation of SMED derived from a novel perspective on mystical experience which may also have some therapeutic utility.

Introduction: The COVID-19 pandemic had significant repercussions for the everyday life and public health of society. Healthcare professionals were particularly vulnerable. Here, we interviewed medical residents about their lived experiences during the pandemic to offer a phenomenological analysis. To this end, we discuss their pandemic experiences considering Jaspers' "limit situation" concept - that is, a radical shift from their everyday experiences, to one causing them to question the basis of their very existence.

Methods: We interviewed 33 medical residents from psychiatry and other specialties from the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP) who either (a) worked directly with COVID-19 patients or (b) provided psychiatric care to other healthcare professionals. Semi-structured interviews were developed using the Inductive Process to Analyze the Structure of lived Experience (IPSE).

Results: The descriptions of the lived experiences of medical residents during the pandemic were organized into four content themes: (a) existential defense, (b) limit situations during the COVID-19 pandemic, (c) changes in lived experience, and (d) new world meanings through lived experience.

Conclusion: During the COVID-19 pandemic, medical residents experienced what can be thought of as a "limit situation," as they encountered the healthcare delivery challenges coupled with the social isolation imposed by the COVID-19 pandemic. These challenges included fear of infection and potential death, uncertainty about the future, and the emotional overload caused by the sharp increase in patient deaths. That said, after facing such a limit situation, residents reported feeling strengthened by this experience. This is consistent with the notion that when confronted with limit situations, we draw on our resources to overcome adversity and, in turn, reap existential gains. Health care providers might use these experiences to energize their own professional approach.

Introduction: The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) contains a dissociative subtype of post-traumatic stress disorder (PTSD) characterized by depersonalization and derealization. Yet, there is evidence that dissociative symptoms in PTSD go beyond this kind of detachment dissociation and that some patients present with additional compartmentalization dissociation in the form of auditory-verbal hallucination, amnesia, and identity alteration.

Methods: Hence, in this study, we examined latent profiles of childhood trauma (Childhood Trauma Questionnaire), PTSD (Impact-of-Event Scale-Revised), and pathological dissociation (Dissociative Experiences Scale-Taxon; DES-T) in a large sample of severely traumatized inpatients with PTSD (N = 1,360).

Results: Results support a three-class solution of the latent profile analysis with a PTSD class, a dissociative subtype class, and a third class characterized by more complex and more severe dissociative symptoms. Importantly, in our inpatient sample of patients with severe PTSD, the latter class was found to be the most prevalent. Both the exploratory character of our retrospective analysis of clinical routine data and the use of the DES-T limit the generalizability of our findings, which require methodologically more rigorous replication.

Conclusion: In severe PTSD, dissociative symptoms beyond detachment are highly prevalent. Diagnostic and treatment implications are discussed.

Dis-sociality (DS) reflects the impairment of social experience in people with schizophrenia; it encompasses both negative features (disorder of attunement, inability to grasp the meaning of social contexts, the vanishing of social shared knowledge) and positive features (a peculiar set of values, ruminations not oriented to reality), reflecting the existential arrangement of people with schizophrenia. DS is grounded on the notion of schizophrenic autism as depicted by continental psychopathology. A rating scale has been developed, providing an experiential phenotype. Here we present the Autism Rating Scale for Schizophrenia - Revised English version (ARSS-Rev), developed on the Italian version of the scale. The scale is provided by a structured interview to facilitate the assessment of the phenomena investigated here. ARSS-Rev is composed of 16 distinctive items grouped into 6 categories: hypo-attunement, invasiveness, emotional flooding, algorithmic conception of sociality, antithetical attitude toward sociality, and idionomia. For each item and category, an accurate description is provided. Different intensities of phenomena are assessed through a Likert scale by rating each item according to its quantitative features (frequency, intensity, impairment, and need for coping). The ARSS-Rev has been able to discriminate patients with remitted schizophrenia from euthymic patients with psychotic bipolar disorder. This instrument may be useful in clinical/research settings to demarcate the boundaries of schizophrenia spectrum disorders from affective psychoses.

Introduction: Abnormal self-experiences are a common feature of major depression despite their absence from current diagnostic manuals. Current diagnostic criteria leave us with an impoverished conception of depressive disorders, and they fail to exploit the diverse experiential alterations that might be useful for understanding and diagnosing patients, and last but not least for explaining the aetiology of these disorders. Although some phenomenological descriptions of abnormal self-experiences in major depression are available, further research is needed to validate these through detailed clinical interviews.

Methods: To characterize these phenomena in more detail and to verify and consolidate previous accounts, we conducted a qualitative study using the Consensual Qualitative Research method.

Results: Our findings identified three categories of abnormal self-experiences: (1) impossibility to project oneself forward, (2) not recognizing one's self, and (3) losing control on one's self.

Conclusion: Before delving into these results, we briefly described how the self is conceptualized in phenomenological psychopathology and explored in the literature on the self-experience in major depression. After discussing our results in the light of recent and contemporary phenomenological literature, we suggest that the inability to recognize otherness as part of oneself - which is the core of depressive experiences - ends in specific symptoms of depersonalization that differ from schizophrenic ones. We conclude that the self-experience, and in particular narrative identity, is central to the development and maintenance of depression.
