Review
BACKGROUND
Previous research has investigated the efficacy of clozapine in reducing suicidality in patients with schizophrenia and schizoaffective disorder. We aimed to systematically review published evidence, including studies concerning clozapine administration to treat: (a) refractory suicidality in other mental disorders, including bipolar disorder and borderline and other personality disorders; and (b) refractory cases of non-suicidal self-injury.
METHOD
We performed a PUBMED-search (last day: July 17, 2022) of English-language studies, combining the keywords "clozapine", "suicidality", and "suicide" with various psychopathological terms (e.g. "schizophrenia"). All duplications were eliminated.
RESULTS
Fifty-one studies were eligible for inclusion in the review. Most studies suggest a superior anti-suicide effect of clozapine in schizophrenia/schizoaffective disorder, compared to other antipsychotics, or no antipsychotic therapy, which is not due to the close monitoring of patients for blood dyscrasias. No consensus exists as to whether other antipsychotic drugs share this effect. Discontinuation of clozapine is associated with increases in suicidality. Reductions in refractory suicidality/NSSI are observed in clozapine-treated patients with bipolar disorder or borderline personality disorder, but the evidence is limited. Potential biological underpinnings of the anti-suicide effect of clozapine include its unique profile of modulation of brain neurotransmitters; its non-selectivity for neurotransmitter receptors; specific genetic and hormonal factors; effects on neuroinflammation; and ability to elicit epileptiform activity.
CONCLUSION
The superior anti-suicide effect of clozapine in schizophrenia/schizoaffective disorder patients is well established. It may have a role in severe and refractory cases of suicidality and non-suicidal self-injury in patients with bipolar disorder or borderline personality disorder, but the level and quality of supporting evidence is limited.

Review
OBJECTIVE
This systematic review sought to summarize comprehensively the research investigating the association between facets of neuroticism and mortality risk.
METHODS
A systematic review of prospective cohort studies utilizing rigorous reporting methods was conducted. Six electronic bibliographic databases, MEDLINE [Ovid], Embase, PsycINFO, CINAHL, Web of Science, and SCOPUS, were searched for eligible studies using keywords encompassing personality traits and mortality. Articles from inception to January 2023 were reviewed. The risk of bias was also assessed.
RESULTS
Six of the 2358 identified studies met the inclusion criteria for extraction. Included studies had 335,715 participants, of whom 3.23% died. Participants ages at baseline ranged from 20 to 102, and 54% were female. Five of the six studies reported statistically significant associations between facets of neuroticism and mortality risk. Several underlying facets were reported to be associated with an increased mortality risk, namely vulnerability, cynicism, pessimistic, anxious, and depressive facets. Inadequacy, and worried-vulnerable were reported as protective. One study reported protective effects for impulsiveness, but this was not observed in a further follow-up study.
CONCLUSIONS
Various facets related to neuroticism are associated with an increased or decreased mortality risk. Encompassing all facets in a broad trait likely masks very important personality-health relations, which later impact longevity. Based on these findings, recommendations and future considerations are discussed.

Review
BACKGROUND
Antipsychotics are a class of medications primarily used to treat individuals with psychotic disorders. They have also been indicated for patients with other psychiatric conditions, such as post-traumatic stress disorder and major depressive disorder. Non-adherence is prominent amongst individuals prescribed antipsychotics, with medication-related self-stigma and social stigma identified as major factors. No previous reviews have focused on stigma associated specifically with antipsychotic medication. This systematic literature review aimed to synthesise evidence on the prevalence of stigmatising attitudes and behaviours related to antipsychotic treatment and understand their impact on antipsychotic treatment initiation and continuation.
METHODS
Two independent reviewers screened studies from databases, congress proceedings, ClinicalTrials.gov, and PsychU.org; relevant studies reported quantitative or qualitative data on antipsychotic-related stigma in adults with psychotic disorders, mood disorders, borderline personality disorder or anxiety disorders, or healthcare providers or caregivers of these patients, and any impact on treatment. Framework synthesis facilitated extraction and synthesis of relevant information; quantitative and qualitative data were coded and indexed against a pre-specified thematic framework by two independent reviewers.
RESULTS
Forty-five articles reporting on 40 unique studies were included; 22 reported quantitative data, 16 reported qualitative data, and two reported quantitative and qualitative data relating to antipsychotic-related stigma. Framework synthesis identified four themes: 1) impact of antipsychotic treatment on a) social stigma or b) self-stigma; 2) impact of side effects of antipsychotic treatment on a) social stigma or b) self-stigma; 3) impact of route of administration of antipsychotic treatment on stigma; 4) impact of stigma on the use of antipsychotics.
CONCLUSION
This systematic literature review found that antipsychotic-related social and self-stigma is a factor in non-adherence to antipsychotics. Further research should examine stigma in a wider range of patients and the extent to which clinicians' treatment decisions are impacted by the potential stigma associated with antipsychotic medications.

Meta-Analysis Review
Psychopathy is a personality construct that encompasses a constellation of traits reflecting emotional dysfunction and antisocial behavior. This constellation has consistently been linked to poor decision-making, often focused on personal and monetary gains at the others' expense. However, there remains a lack of a systematic examination of how psychopathy is related to the prospect of obtaining monetary gains as a function of social context. Therefore, we conducted a series of meta-analyses to elucidate these relationships. Our findings indicated that elevated levels of psychopathy are related to a reduced tendency to cooperate with others, and no difference in the extent to which knowledge of others' retaliation possibilities informs decision-making. However, the type of social economic decision-making game employed moderated the association between psychopathic traits and total gain obtained, suggesting that context plays a key role in moderating the link between psychopathic features and decision-making. These findings advance our understanding of psychopathy and open new avenues for research on adaptive and maladaptive social behavior in individuals with high levels of psychopathic traits.

Review
Psychiatric Treatment Conducted via Telemedicine Versus In-Person Modality in Posttraumatic Stress Disorder, Mood Disorders, and Anxiety Disorders: Systematic Review and Meta-Analysis.
BACKGROUND
Telemedicine has played a vital role in providing psychiatric treatment to patients during the rapid transition of services during the COVID-19 pandemic. Furthermore, the use of telemedicine is expected to expand within the psychiatric field. The efficacy of telemedicine is well described in scientific literature. However, there is a need for a comprehensive quantitative review that analyzes and considers the different clinical outcomes and psychiatric diagnoses.
OBJECTIVE
This paper aimed to assess whether individual psychiatric outpatient treatment for posttraumatic stress disorder, mood disorders, and anxiety disorders in adults using telemedicine is equivalent to in-person treatment.
METHODS
A systematic search of randomized controlled trials was conducted using recognized databases for this review. Overall, 4 outcomes were assessed: treatment efficacy, levels of patient satisfaction, working alliance, and attrition rate. The inverse-variance method was used to summarize the effect size for each outcome.
RESULTS
A total of 7414 records were identified, and 20 trials were included in the systematic review and meta-analysis. The trials included posttraumatic stress disorder (9 trials), depressive disorder (6 trials), a mix of different disorders (4 trials), and general anxiety disorder (1 trial). Overall, the analyses yielded evidence that telemedicine is comparable with in-person treatment regarding treatment efficacy (standardized mean difference -0.01, 95% CI -0.12 to 0.09; P=.84; I=19%, 17 trials, n=1814), patient satisfaction mean difference (-0.66, 95% CI -1.60 to 0.28; P=.17; I=44%, 6 trials, n=591), and attrition rates (risk ratio 1.07, 95% CI 0.94-1.21; P=.32; I=0%, 20 trials, n=2804). The results also indicated that the working alliance between telemedicine and in-person modalities was comparable, but the heterogeneity was substantial to considerable (mean difference 0.95, 95% CI -0.47 to 2.38; P=.19; I=75%, 6 trials, n=539).
CONCLUSIONS
This meta-analysis provided new knowledge on individual telemedicine interventions that were considered equivalent to in-person treatment regarding efficacy, patient satisfaction, working alliance, and attrition rates across diagnoses. The certainty of the evidence regarding efficacy was rated as moderate. Furthermore, high-quality randomized controlled trials are needed to strengthen the evidence base for treatment provided via telemedicine in psychiatry, particularly for personality disorders and a range of anxiety disorders where there is a lack of studies. Individual patient data meta-analysis is suggested for future studies to personalize telemedicine.

OBJECTIVE
To examine personality/temperament features and mental health vulnerability in offspring of mothers with bipolar disorders (BD), including dimensions which may impact psychological characteristics or therapeutic measures.
METHODS
A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, was conducted to search for original articles that investigated personality/temperament features of offspring of women with BD and emotional factors involved in the mother-child relationship. The electronic search was performed in the PubMed, Web of Science, and PsycINFO databases from February 2010 to February 2017.
RESULTS
Ten quantitative studies were included in the analysis: seven from the United States, two from Brazil, and one from Canada. The narrative synthesis was categorized into three dimensions: 1) reliability of instruments for prediction of future psychopathology in offspring; 2) environmental risk factors for offspring; and 3) early interventions. The findings showed impairments in the offspring's lives, high rates of behavior and temperament problems, and psychiatric disorders.
CONCLUSION
BD is a frequent psychiatric disorder, and the offspring of mothers with this condition are exposed to complex family relationships and psychosocial difficulties. If they are to ensure a good provision of mental health and psychosocial care to this unique population, early interventions must not neglect their contextual specificities.

BACKGROUND
Dissociation, which is defined as the failure to associate consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior into an integrated whole, has long been assumed to be generated by trauma. If dissociation is a product of trauma exposure, then dissociation would be a major mental health outcome observed in studies of disaster survivors. Although some studies have examined dissociation in disasters, no systematic literature reviews have been conducted to date on the topic.
AIM
To systematically evaluate the literature on the association between disaster and dissociation to determine the prevalence and incidence of dissociation after exposure to disaster and further examine their relationship.
METHODS
EMBASE, Medline, and PsychINFO were searched from inception to January 1, 2019 to identify studies examining dissociative disorders or symptoms related to a disaster in adult or child disaster survivors and disaster responders. Studies of military conflicts and war, articles not in English, and those with samples of 30 or more participants were excluded. Search terms used were "disaster*" and dissociation ("dissociat*," "multiple personality," "fugue," "psychogenic amnesia," "derealization," and "depersonalization"). Reference lists of identified articles were scrutinized to identify studies for additional articles.
RESULTS
The final number of articles in the review was 53, including 36 articles with samples of adults aged 18 and above, 5 of children/adolescents under age 18, and 12 of disaster workers. Included articles studied several types of disasters that occurred between 1989 and 2017, more than one-third (38%) from the United States. Only two studies had a primary aim to investigate dissociation in relation to disaster and none reported data on dissociative disorders. All of the studies used self-report symptom scales; none used structured interviews providing full diagnostic assessment of dissociative disorders or other psychopathology. Several studies mixed exposed and unexposed samples or did not differentiate outcomes between exposure groups. Studies examining associations between dissociation and disaster exposure have been inconclusive. The majority (75%) of the studies compared dissociation with posttraumatic stress, with inconsistent findings. Dissociation was found to be associated with a wide range of other psychiatric disorders, symptoms, and negative emotional, cognitive, and functional states.
CONCLUSION
The studies reviewed had serious methodological limitations including problems with measurement of psychopathology, sampling, and generation of unwarranted conclusions, precluding conclusions that dissociation is an established outcome of disaster.

BACKGROUND
Smartphone applications could improve symptoms of borderline personality disorder (BPD) in a scalable and resource-efficient manner in the context limited access to specialized care.
OBJECTIVE
This systematic review and meta-analysis aims to evaluate the effectiveness of applications designed as treatment interventions for adults with symptoms such as anger, suicidality, or self-harm that commonly occur in BPD.
DATA SOURCES
Search terms for BPD symptoms, smartphone applications, and treatment interventions were combined on PubMed, MEDLINE, and PsycINFO from database inception to December 2019.
STUDY SELECTION
Controlled and uncontrolled studies of smartphone interventions for adult participants with symptoms such as anger, suicidality, or self-harm that commonly occur in BPD were included.
STUDY APPRAISAL AND SYNTHESIS METHODS
was used to compute between-groups effect sizes in controlled designs. The primary outcome was BPD-related symptoms such as anger, suicidality, and impulsivity; and the secondary outcome was general psychopathology. An average dropout rate across interventions was computed. Study quality, target audiences, therapeutic approach and targets, effectiveness, intended use, usability metrics, availability on market, and downloads were assessed qualitatively from the papers and through internet search.
RESULTS
Twelve studies of 10 applications were included, reporting data from 408 participants. Between-groups meta-analyses of RCTs revealed no significant effect of smartphone applications above and beyond in-person treatments or a waitlist on BPD symptoms (Hedges' = - 0.066, 95% CI [-.257, .125]), nor on general psychopathology (Hedges' = 0.305, 95% CI [- 0.14, 0.75]). Across the 12 trials, dropout rates ranged from 0 to 56.7% ( = 22.5, 95% CI [0.15, 0.46]). A majority of interventions studied targeted emotion dysregulation and behavioral dyscontrol symptoms. Half of the applications are commercially available.
CONCLUSIONS
The effects of smartphone interventions on symptoms of BPD are unclear and there is currently a lack of evidence for their effectiveness. More research is needed to build on these preliminary findings in BPD to investigate both positive and adverse effects of smartphone applications and identify the role these technologies may provide in expanding mental healthcare resources.

Review
Williams Syndrome (WS) is a rare genetic multisystem disorder that occurs because of a deletion of approximately 25 genes in the 7q11.23 chromosome region. This causes dysmorphic facial appearances, multiple congenital cardiovascular defects, delayed motor skills, and abnormalities in connective tissues and the endocrine system. The patients are mostly diagnosed with mild to moderate mental retardation, however, they have a hyper sociable, socially dis-inhibited, and outgoing personality, empathetic behavior, and are highly talkative. Oxytocin (OT), a neuropeptide synthesized at the hypothalamus, plays an important role in cognition and behavior, and is thought to be affecting WS patients' attitudes at its different amounts. Oxytocin receptor gene (), on chromosome 3p25.3, is considered regulating oxytocin receptors, via which OT exerts its effect. WS is a crucial disorder to understand gene, hormone, brain, and behavior associations in terms of sociality and neuropsychiatric conditions. Alterations to the WS gene region offer an opportunity to deepen our understandings of autism spectrum disorder, schizophrenia, anxiety, or depression. We aim to systematically present the data available of OT/ regulation and expression, and the evidence for whether these mechanisms are dysregulated in WS. These results are important, as they predict strong epigenetic control over social behavior by methylation, single nucleotide polymorphisms, and other alterations. The comparison and collaboration of these studies may help to establish a better treatment or management approach for patients with WS if backed up with future research.

INTRODUCTION
research carried out regarding the psychological concept of schizotypy responds to a field of extensive development since its conceptualization decades ago, which includes schizophrenia spectrum disorders (SSD) and schizotypal personality disorder (SPD). However, controversies still persist marked by the difficulty of establishing definitive consensus.
OBJECTIVE
the research purpose aimed to synthesize the empirical evidence involved in the use of various methodologies and tools for understanding schizotypy.
METHODOLOGY
A systematic review was carried out in the following databases: Web of Science, Scopus, PubMed, Taylor and Francis, Wiley, Science Direct, Google Scholar, and PsycNet. By using the PRISMA guidelines, 65 studies published in the last decade (2010-2020) were discriminated.
RESULTS
The synthesis of cumulative knowledge made it possible to define schizotypy as an integrating multidimensional construct and to identify valid assessment tools in use, in its psychometric, clinical, and personality characterizations.
DISCUSSION/CONCLUSIONS
Clinical implications found in these reports are addressed, as well as notions of the continuum of psychoses, taxonomic, and multidimensional models.
