Most research on mass murderers to date has focused on perpetrators of male sex, while research on perpetrators of female sex has been relegated to case reports and series. We aimed to more fully examine the phenomenon of female‐perpetrated mass murder. We analyzed 1715 worldwide incidents of personal‐cause mass murder from 1900 to 2019, identifying 105 (6%) events perpetrated by females. We defined mass murder as any event involving at least three fatalities, not including the perpetrator, using any method. We identified cases of mass murder from English‐language databases of mass murder or murder in print or online. There were no significant differences in age and race between female and male perpetrators. Relative to males, female perpetrators were significantly less likely to employ firearms in their mass murders, using them in less than half of cases, compared to over 70% for males. The prevalence of psychotic signs and symptoms among female mass murderers was more than double that among males (25.7% vs. 12.5%, p < 0.01), while the rate of nonpsychotic psychiatric or neurological conditions was also much greater among female perpetrators (29.5% vs. 17.1%, p < 0.01). Over half of female perpetrators took or attempted to take their own lives. More than three‐quarters of mass murders by females involved at least one family member as a victim. This study underscores sex‐specific differences in the perpetration of mass murder and the need for further research to understand how insights about such dynamics might lead to the development of more effective and informed intervention policies.

Background: Mass shootings account for a small fraction of annual worldwide murders, yet disproportionately affect society and influence policy. Evidence suggesting a link between mass shootings and severe mental illness (i.e. involving psychosis) is often misrepresented, generating stigma. Thus, the actual prevalence constitutes a key public health concern. Methods: We examined global personal-cause mass murders from 1900 to 2019, amassed by review of 14 785 murders publicly described in English in print or online, and collected information regarding perpetrator, demographics, legal history, drug use and alcohol misuse, and history of symptoms of psychiatric or neurologic illness using standardized methods. We distinguished whether firearms were or were not used, and, if so, the type (non-automatic v. semi- or fully-automatic). Results: We identified 1315 mass murders, 65% of which involved firearms. Lifetime psychotic symptoms were noted among 11% of perpetrators, consistent with previous reports, including 18% of mass murderers who did not use firearms and 8% of those who did (χ2 = 28.0, p < 0.01). US-based mass shooters were more likely to have legal histories, use recreational drugs or misuse alcohol, or have histories of non-psychotic psychiatric or neurologic symptoms. US-based mass shooters with symptoms of any psychiatric or neurologic illness more frequently used semi-or fully-automatic firearms. Conclusions: These results suggest that policies aimed at preventing mass shootings by focusing on serious mental illness, characterized by psychotic symptoms, may have limited impact. Policies such as those targeting firearm access, recreational drug use and alcohol misuse, legal history, and non-psychotic psychopathology might yield more substantial results.

Background: Affective polarization and stigma toward individuals with schizophrenia and toward immigrants in Argentina are not new despite its importance and dissemination. However, no research has been conducted taking into consideration political partisanship and attitudes toward these groups. Aims: Political polarization and attitudes toward socialization across party lines are studied in conjunction with attitudes toward immigrants and toward individuals with schizophrenia. Method: Individuals from Buenos Aires (n = 712) were surveyed for their political partisanship and their attitudes toward Peruvian and Bolivian immigrants, people with schizophrenia and partisans from the opposing political party. A modified version of the Bogardus scale was used. Results: Social distance was from highest to lowest toward people with schizophrenia, political opponents, and immigrants. Individuals with schizophrenia were strongly discriminated against by most participants: 86% would definitely or probably not want them to take care of their children, 83% would not want them to be their healthcare provider, and 81% would not want to marry them. Immigrants were comparatively not discriminated against: 10% would not want them to take care of their children, 8% would not want to receive health care from them, and 28% would not want to marry them. Cristina Fernández de Kirchner partisans showed the lowest level of discrimination toward these two groups, compared to Mauricio Macri partisans and to independent voters. However, the former group had greater discriminatory attitudes toward Mauricio Macri partisans than the latter. Conclusions: As compared to other discriminatory attitudes, discrimination toward persons with schizophrenia is widespread and pervasive. Lower levels of discrimination toward people with schizophrenia and toward immigrants would not predict attitudes toward the opposing political partisans. [ABSTRACT FROM AUTHOR]

Aim: We sought to explore the complex phenomenological overlap between obsessive and compulsive symptoms (OCS), and attenuated positive symptoms among 156 young people at clinical high‐risk (CHR) for psychosis. Methods: In order to explore the hypothesis that OCS of an implausible nature might optimally predict future transition to syndromal psychosis, ideas associated with obsessive and compulsive experiences elicited by clinical measures were thematically categorized as "plausible" or "implausible." Results: While OCS were found to be common in our CHR sample, we did not find that implausible OCS themes were predictive of conversion. Conclusion: Given the absence of qualitative differences between OCS and early psychotic symptoms, we propose that clinicians encountering adolescent or young adult patients with new‐onset OCD or OCS in the past year should monitor such symptoms for a minimum of 2 years to assess for the possible emergence of psychosis.

Aim: Fuelled by genomics advances, recent emphasis on the concept of "precision medicine," and public optimism towards genetic advances, it is important to understand how those who are considered to be at clinical high‐risk for psychosis (CHR) perceive possible benefits of genetic testing to inform future stakeholder education efforts. Methods: Semistructured interviews were completed with 20 participants who met CHR criteria. Coding for genetic optimism was completed. Results: Participants endorsed many conceptualizations of the link between genetics, the development of psychosis, and the benefits of genetic testing. Specifically, themes emerged surrounding how genetic testing may lead to greater genetic knowledge and tailored treatment. Conclusions: Our results demonstrate that CHR participants generally endorse several precision psychiatry concepts, including how genetic testing may lead to tailored treatment advances. This knowledge may aid development of best communication practices regarding forthcoming genetic advances in diagnosis and treatment among CHR. [ABSTRACT FROM AUTHOR]

Background: Early detection and intervention strategies in patients at clinical high-risk (CHR) for syndromal psychosis have the potential to contain the morbidity of schizophrenia and similar conditions. However, research criteria that have relied on severity and number of positive symptoms are limited in their specificity and risk high false-positive rates. Our objective was to examine the degree to which measures of recency of onset or intensification of positive symptoms [a.k.a., new or worsening (NOW) symptoms] contribute to predictive capacity. Methods: We recruited 109 help-seeking individuals whose symptoms met criteria for the Progression Subtype of the Attenuated Positive Symptom Psychosis-Risk Syndrome defined by the Structured Interview for Psychosis-Risk Syndromes and followed every three months for two years or onset of syndromal psychosis. Results: Forty-one (40.6%) of 101 participants meeting CHR criteria developed a syndromal psychotic disorder [mostly (80.5%) schizophrenia] with half converting within 142 days (interquartile range: 69–410 days). Patients with more NOW symptoms were more likely to convert (converters: 3.63 ± 0.89; non-converters: 2.90 ± 1.27; p = 0.001). Patients with stable attenuated positive symptoms were less likely to convert than those with NOW symptoms. New, but not worsening, symptoms, in isolation, also predicted conversion. Conclusions: Results suggest that the severity and number of attenuated positive symptoms are less predictive of conversion to syndromal psychosis than the timing of their emergence and intensification. These findings also suggest that the earliest phase of psychotic illness involves a rapid, dynamic process, beginning before the syndromal first episode, with potentially substantial implications for CHR research and understanding the neurobiology of psychosis.

Background: Few studies provide clear rationale for and the reception of adaptations of evidence-based interventions. To address this gap, we describe the context-dependent adaptations in critical time intervention-task shifting (CTI-TS), a manualized recovery program for individuals with psychosis in Rio de Janeiro, Brazil and Santiago, Chile. Implications of the adaptations – incorporating a task-shifting approach and modifying the mode of community-based service delivery – are examined from users' perspectives. Methods: A secondary analysis of in-depth interviews with CTI-TS users (n = 9 in Brazil; n = 15 in Chile) was conducted. Using the framework method, we thematically compared how participants from each site perceived the main adapted components of CTI-TS. Results: Users of both sites appreciated the task-shifting worker pair to provide personalized, flexible, and relatable support. They wanted CTI-TS to be longer and experienced difficulty maintaining intervention benefits in the long-term. In Chile, stigma and a perceived professional hierarchy toward the task-shifting providers were more profound than in Brazil. Engagement with community-based services delivery in homes and neighborhoods (Chile), and at community mental health centers (Brazil) were influenced by various personal, familial, financial, and social factors. Uniquely, community violence was a significant barrier to engagement in Brazil. Conclusion: CTI-TS' major adaptations were informed by the distinct mental health systems and social context of Santiago and Rio. Evaluation of user experiences with these adaptations provides insights into implementing and scaling-up task-shifting and community-oriented interventions in the region through the creation of specialized roles for the worker pair, targeting sustained intervention effects, and addressing socio-cultural barriers.

Background: Posttraumatic stress related with the childbirth experience of full-term delivery with health outcomes has been recently documented in a growing body of studies. The magnitude of this condition and the factors that might put a woman at risk for developing childbirth-related postpartum posttraumatic stress disorder (PP-PTSD) symptoms are not fully understood. Methods: In this systematic review of 36 articles representing quantitative studies of primarily community samples, we set to examine PP-PTSD prevalence rates and associated predictors with a focus on the role of prior PTSD and time since childbirth. Results: A significant minority of women endorsed PP-PTSD following successful birth. Acute PP-PTSD rates were between 4.6 and 6.3%, and endorsement of clinically significant PP-PTSD symptoms was identified in up to 16.8% of women in community samples of high quality studies. Negative subjective experience of childbirth emerged as the most important predictor. Endorsement of PTSD before childbirth contributed to PP-PTSD; nevertheless, women without PTSD also exhibited PP-PTSD, with acute rates at 4.6%, signifying a new PTSD onset in the postpartum period. Conclusion: Although the majority of women cope well, childbirth for some can be perceived as a highly stressful experience and even result in the development of PP-PTSD symptoms. More research is needed to understand postpartum adaption and childbirth-related posttraumatic stress outcomes.

Objective: Stigma jeopardizes recovery and successful implementation of mental health services (MHS) globally. Despite cultural variation in how stigma manifests, few studies have examined how culture fundamentally impacts the concept of "personhood" in Latin America. Chile has expanded MHS, providing universal coverage for evaluation and treatment of first episode psychosis (FEP). We applied the "what matters most" (WMM) framework of stigma to identify culturally salient factors that shape or protect against stigma in urban Chile, identifying potential implications for MHS and recovery. Methods: In-depth interviews (n = 48) were conducted with MHS users with psychotic disorders (n = 18), their family members (n = 15), and community members (n = 15), from two urban regions in Chile. Interviews were coded and analyzed to identify WMM, how WMM shapes stigma, and how MHS can influence achieving WMM. Results: Traditional values emphasizing physical/social appearance, gender roles, family, and social connectedness are highly valued. Socioeconomic transitions have engendered capitalistic variations on traditional values, with increasing emphasis on professional careers for men and women, individualism, and independence. Psychotic disorders interfere with fulfillment of both traditional and capitalist values, thereby reinforcing stigma. However, MHS are seen as partially effective in enabling fulfillment of some goals, including employment, appearance, and independence, while often remaining insufficient in enabling capacity to achieve marriage and having a family. Conclusions and Implications for Practice: MHS that facilitate recovery by engaging users in services, such as pharmacotherapy, education/vocational rehabilitation, and family-centered care aligned with cultural values can mitigate stigma and facilitate recovery by enabling users to fulfill WMM. Impact and Implications: Both traditional and capitalist values influence users of mental health services in urban Chile. Mental illness shapes stigma by interfering with widely valued goals of maintaining a good appearance, marriage and family formation, social connectedness, and independence. Mental health services have both positive and negative impacts on users' achievement of these goals. Future mental health services development can reduce stigma by aligning services with lived values. [ABSTRACT FROM AUTHOR]
