Intimate partner violence survivors' reported experiences of discrimination in mental health treatment settings.

Research indicates that survivors of intimate partner violence (IPV) face substantial stigma and discrimination, with varying impacts based on demographic factors such as race and income. This study explored perceived discrimination among 88 IPV survivors across different racial backgrounds and income levels in mental health settings. Participants completed a mixed-method electronic survey assessing discrimination experiences related to survivor status, income, and race within mental health treatment. Results revealed high levels of perceived discrimination based on survivor status among both racially minoritized and majoritized survivors. However, racially minoritized survivors reported greater racial discrimination and associated stress within mental healthcare settings. Regardless of income level, all survivors reported significant discrimination experiences. Qualitative analysis highlighted factors perceived as helpful or unhelpful within mental health settings. This study underscores the need for further research on socioeconomic influences on stigma experiences among IPV survivors and suggests implications for provider training to better support survivors, especially those from diverse racial backgrounds.

Training guidelines and competencies for serious mental illness (SMI) psychology.

Individuals with serious mental illness (SMI) face unique and significant challenges that require evidence-based practices and clinicians who have advanced, comprehensive training to provide them. SMI affects about 5.5% of the U.S. population and results in serious health, social, and economic burdens. Despite advancements in treatment over the past 50 years, training programs for psychologists and other mental health providers have failed to keep up with these advances, underutilizing evidence-based assessments and interventions developed specifically for this population and found to be efficacious. To address this, the SMI Psychology Specialty has developed Training Guidelines to establish consistent, high-quality, and evidence-based training for postdoctoral psychologists. This article highlights selected features of the Training Guidelines for SMI Psychology. Although these were developed for postdoctoral training programs in SMI Psychology, they are applicable to training programs at all levels, and we hope that training programs in psychology and other mental health disciplines will incorporate these advances into their curricula.

Service User Representation in Qualitative Research on Cognitive Health and Related Interventions for Psychosis: A Scoping Review.

BACKGROUND AND HYPOTHESIS: Cognitive health in schizophrenia spectrum psychosis has received substantial empirical attention in recent decades, coinciding with the development and implementation of interventions including cognitive remediation. Subjective experience in psychosis, including qualitative explorations of service user perspectives, has also proliferated; however, there is no available synthesis of service user representation in the psychosis cognitive health literature. This scoping review investigated prevalence and characteristics of qualitative research reporting service user perspectives across the extant research on cognitive health and related interventions in psychosis. STUDY DESIGN: We conducted a literature search on qualitative methods in cognitive health and/or related interventions across PubMed, Web of Science, and PsycInfo databases. The review followed the PRISMA-ScR guidelines for scoping reviews and identified 23 papers. Data extraction included study design and sample characteristics, qualitative methodology, and reporting. STUDY RESULTS: Of 23 articles, 18 reported on user experiences of interventions, most often in the context of feasibility/acceptability for otherwise quantitative trials. Five studies described service user experiences of cognitive health separately from interventions. Only 3 included any service user involvement or participatory methods. Twenty articles reported any demographic characteristics, and fewer than half (11) reported any racial or ethnic sample characteristics. There was substantial variability in qualitative methodology and reporting across studies. CONCLUSIONS: Qualitative methodology is lacking in its representation and rigor across the cognitive health literature for schizophrenia spectrum psychosis. Additional inclusion of service user lived experience is critical for future research to better characterize cognitive health and inform interventions to promote recovery.

Community member attitudes and understanding of "serious mental illness": A mixed-method study.

OBJECTIVE: "Serious mental illness" (SMI) is a priority population within mental health treatment and policy. However, there is no standard operational definition across research, clinical, and policy contexts. The use of the label has also not been evaluated regarding its association with stigma among the general public. This mixed-method study compared community members' stigma toward "SMI" with other psychiatric labels and examined community understanding and perceptions of the SMI label. METHOD: Two hundred forty-six participants recruited via Prolific read randomly manipulated vignettes describing an individual diagnosed with depression, schizophrenia, or "SMI" and completed measures of stigma and qualitative questions regarding familiarity, understanding, and perceived utility of SMI. Quantitative analyses evaluated stigma across vignettes, and qualitative analyses identified common themes across responses. RESULTS: Stigma was relatively high across vignettes, with more negative views reported toward SMI and schizophrenia compared with depression. Quantitative differences in stigma by vignette were not significant after controlling for participants' age and gender. Qualitative responses were split regarding the perceived utility of the SMI term, with noted concerns including its broadness and potential for stigma. Most participants described functional impairment or disability as characteristic of "SMI," and approximately 70% associated schizophrenia and psychotic disorders with "SMI" compared with 45% for depression. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Person-level factors were more strongly associated with stigma than psychiatric labels. However, our sample described concerns that the SMI term is vague and may exacerbate stigma. Community education and antistigma efforts should move beyond diagnostic labels in characterizing mental illness to facilitate change in attitudes.

Prosumers' experiences of witnessed discrimination and internalized stigma: A moderated mediation.

Discrimination toward individuals with lived experiences of mental illness is widespread within the field of clinical psychology. Further, there is some presence of clinical psychologists who are both consumers and providers of mental health services, termed prosumers. However, no research has evaluated how witnessing discrimination as part of professional activities may influence prosumers' experiences with internalized stigma, anticipated stigma, and stigma resistance. This exploratory study aimed to establish associations and interactions between having witnessed discrimination toward others with lived experiences of mental illness and internalized stigma, anticipated stigma, and stigma resistance from the perspective of prosumers within the clinical psychology field. A cross-sectional quantitative approach was employed to understand these dynamics by utilizing descriptive, correlational, and multivariate regressions analysis. A total 175 prosumers (39 graduated doctoral-level clinical psychologists and 136 in training) completed survey measures pertaining to witnessed discrimination, internalized and anticipated stigma, and stigma resistance. Prosumers reported witnessing frequent subtle and overt discrimination by their colleagues, supervisors, and faculty members. Overt discrimination was reported as witnessed more frequently compared with subtle discrimination experiences or microaggressions. Our findings have implications for the prevalence of witnessed discrimination and how these may create cumulative experiences of stigma and stigma resistance among prosumers in clinical psychology. Further research should explore additional understanding of how clinical psychologists, including prosumers, may hold stigmatizing attitudes and perpetuate discrimination toward individuals with lived experiences of mental illness.

Dental tissue changes in juvenile and adult mice with osteogenesis imperfecta.

Osteogenesis imperfecta (OI), a disorder of type I collagen, causes skeletal deformities as well as defects in dental tissues, which lead to increased enamel wear and smaller teeth with shorter roots. Mice with OI exhibit similar microstructural dentin changes, including reduced dentin tubule density and dentin cross-sectional area. However, the effects of these mutations on gross dental morphology and dental tissue volumes have never been characterized in the osteogenesis imperfecta murine (OIM) mouse model. Here we compare mineralized dental tissue measurements of OIM mice and unaffected wild type (WT) littermates at the juvenile and adult stages. The maxillary and mandibular incisors and first molars were isolated from microCT scans, and tissue volumes and root length were measured. OIM mice have smaller teeth with shorter roots relative to WT controls. Maxillary incisor volumes differed significantly between OIM and WT mice at both the juvenile and young adult stage, perhaps due to shortening of the maxilla itself in OIM mice. Additionally, adult OIM mice have significantly less crown enamel volume than do juveniles, potentially due to loss through wear. Thus, OIM mice demonstrate a dental phenotype similar to humans with OI, with decreased tooth size, decreased root length, and accelerated enamel wear. Further investigation of dental development in the OIM mouse may have important implications for the development and treatment of dental issues in OI patients.

Neurocranial growth in the OIM mouse model of osteogenesis imperfecta.

Osteogenesis imperfecta (OI) is a disorder of type I collagen characterized by abnormal bone formation. The OI craniofacial phenotype includes midfacial underdevelopment, as well as neurocranial changes (e.g., macrocephaly and platybasia) that may also affect underlying nervous tissues. This study aims to better understand how OI affects the integrated development of the neurocranium and the brain. Juvenile and adult mice with OI (OIM) and unaffected wild type (WT) littermates were imaged using in vivo micro-computed tomography (microCT). Virtual endocast models were used to measure brain volume, and 3D landmarks were collected from the cranium and brain endocasts. Geometric morphometric analyses were used to compare brain shape and integration between the genotypes. OIM mice had increased brain volumes (relative to cranial centroid size) only at the juvenile stage. No significant difference was seen in cranial base angle (CBA) between OIM and WT mice. However, CBA was higher in juvenile than in adult OIM mice. Brain shape was significantly different between OIM and WT mice at both stages, with OIM mice having more globular brains than WT mice. Neurocranial and brain morphology were strongly integrated within both genotypes, while adult OIM mice tended to have lower levels of skull-brain integration than WT mice. These results suggest that neurocranial dysmorphologies in OI may be more severe at earlier stages of postnatal development. Decreased skull-brain integration in adult mice suggests that compensatory mechanisms may exist during postnatal growth to maintain neurological function despite significant changes in neurocranial morphology.

Morphological variability in the inner ear of mice with osteogenesis imperfecta.

Osteogenesis imperfecta (OI) is known to cause hearing loss in ~60% of the affected human population. While OI-related pathologies have been studied in the middle ear, the development of cochlear pathologies is less well understood. In this study, we examine OI-related pathologies of the cochlea in a mouse model of OI to (1) document variation between OI and unaffected mice, and (2) assess the intrusion of the otic capsule onto the cochlea by analyzing differences in duct volumes. Juvenile and adult OIM C57BL/6mice were compared to unaffected wildtype (WT) mice using three-dimensional models of the cochlea generated from high resolution micro-CT scans. Two-tailed Mann-Whitney U tests were then used to investigate duct volume differences both within and between the OI and WT samples. Areas of higher ossification were observed at the cochlear base in the OI sample. OI mice also had significant intraindividual differences in duct volume between right and left ears (4%-15%), an effect not observed in WT mice. WT and OI duct volumes showed a large degree of overlap, although the OIM volumes were more variable. Our findings indicate that OIM mice are likely to exhibit more asymmetry and variation in cochlear volume despite minor differences in sample cochlear volumes, possibly due to bony capsule intrusion. This suggests a potential mechanism of hearing loss, and a high potential for cochlear and otic capsule alteration in OIM mice.

Prosumers' experiences of stigma dimensions within the clinical psychology field.

Lived experiences of mental illness and stigmatizing attitudes toward psychiatric diagnoses are common throughout the world. Research demonstrates that clinical psychologists are not exempt from having lived experiences of mental illness, nor experiencing, witnessing and perpetuating stigma. However, no research has examined prosumers' (providers and consumers of mental health services) experiences of witnessing discrimination within the field of clinical psychology. The purpose of this study was to explore prosumer's experiences of stigma within clinical psychology. A total of 175 doctoral level prosumers (graduated N = 39 and N = 136 in-training) completed a mixed-method online survey regarding their stigma experiences within the field. Emergent qualitative themes from grounded theory analyses included: witnessed discrimination (invalidation, over pathologizing, clinical psychologists as experts and training as a breeding ground for stigma, psychological distress, negative feelings related to field), anticipated stigma (agency and identity rejected, degree of acceptance), internalized stigma (perceived competence and social desirability), and stigma resistance (academia in action, engaging communities, comes with a risk, worthwhile). Our findings have implications for the role of clinical psychology in perpetuating stigmatizing views and attitudes toward individuals with lived experiences of mental illness, specifically in-training and academic settings. Further research should strive to evaluate how clinical psychologists, including prosumers, engage in stigma, and the associations between discrimination and other stigma dimensions.

Policy Definitions for "Serious Mental Illness" Across 56 United States, Districts and Territories.

The construct "serious/severe mental illness," or "SMI," is a priority within mental health initiatives in the United States. However, there is a lack of clarity regarding its operational definition in policy and practice settings. This study involved an evaluation of "SMI" policy definitions across the 50 United States, five territories, and Washington, D.C. via review of public legislation, department of health (DOH) websites and contacts. Policy definitions were available for 46 (82.2%) locations. Of those definitions, 32 (69.6%) were listed within legislation and 18 (39.1%) used pre-existing organizational or agency definitions. Only nine (19.6%) definitions indicated they were intended to determine eligibility for specific mental health services. Most locations (N = 38; 82.6%) mentioned functional impairment or disability as an eligibility criterion and suggested any psychiatric diagnosis could be considered SMI (N = 34; 73.9%). Results indicate substantial variability in SMI policy definitions across geographic locations with implications for service eligibility, delivery, and receipt.

Reliability of the Term "Serious Mental Illness": A Systematic Review.

OBJECTIVE: The term "serious mental illness" (SMI) is widely used across research, practice, and policy settings. However, there is no consistent operational definition, and its reliability has not been systematically evaluated. The purpose of this review was to provide a comprehensive qualitative content analysis of "SMI" empirical research, including study and sample characteristics and SMI operational definitions. These data can provide important considerations for how stakeholders conceptualize SMI. METHODS: Systematic review of PsycInfo, PsycArticles, and PubMed databases from January 1, 2015, to December 31, 2019, identified 788 original empirical studies that characterized the sample as having "SMI." RESULTS: Descriptive content analysis indicated that most studies (85%) provided no operational definition for SMI. Only 15% defined the term, and an additional 26% provided examples of SMI that included only psychiatric diagnostic categories (e.g., SMI, such as schizophrenia). Of the 327 studies that provided any description of SMI, variability was noted regarding whether criteria included any mental health diagnosis (N=31) or only specified diagnoses (N=289), functional impairment (N=73), or any specified duration of symptoms (N=39). Across all studies that characterized samples as having SMI, substantial variability was noted regarding included diagnostic classifications. CONCLUSIONS: Referencing "SMI" is second nature for many stakeholders. Findings suggest that evidence-based practice and policy efforts should weigh the level of research support indicating that the construct and the term "SMI" lacks generalizability. Researchers and stakeholders are encouraged to develop precise and agreed-upon diagnostic language in their efforts to support and advocate for people with mental illnesses.

Neuropsychological deficits associated with medical conditions: Implications for psychological services in criminal legal settings.

Criminal legal system-involved populations are disproportionally impacted by chronic health conditions relative to the general population. These discrepancies are thought to be due to both health disparities and increased likelihood to engage in health-compromising behaviors. Medical conditions can significantly influence neuropsychological functioning and, in turn, thinking and behavior relevant to clinical forensic decision-making and psychological practice in criminal legal settings. The aim of this article is to review medical conditions commonly observed among system-involved populations-specifically cardiovascular disease, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), traumatic brain injury, cancer, diabetes, and medication side effects-and describe the complex and important links between these conditions, their associated neuropsychological deficits, and applications to psychological assessment and treatment in criminal legal settings. Ultimately, this discussion will be useful to staff providing psychological services in these settings by increasing their familiarity with these concepts, and providing practical applications to inform their case conceptualization, assessment, and treatment services with system-involved individuals.

Understanding weight stigma in eating disorder treatment: Development and initial validation of a treatment-based stigma scale.

Weight stigma is a well-established risk factor for eating disorder pathology, and it is prevalent among healthcare professionals. The current investigation developed and psychometrically validated the Scale for Treatment-based Experiences of Weight Stigma (STEWS) for patient-centered assessment of weight-stigmatizing experiences in eating disorder treatment. Former eating disorder patients (N = 142) with a body-mass-index greater than 25.0 were recruited via Amazon Mechanical Turk. The STEWS demonstrated good internal consistency, convergent validity with widely used weight stigma scales, and incremental validity in predicting eating disorder symptomatology. The STEWS is the first psychometrically sound instrument for treatment-based weight stigma in eating disorder recovery.

Variation in provider attitudes and treatment recommendations for individuals with schizophrenia and additional marginalized identities: A mixed-method study.

Objective: This study evaluated correlates of mental health stigma among treatment providers, including whether provider attitudes, conceptualizations, and treatment recommendations regarding serious mental illness (SMI) may differ depending on client demographic characteristics. Methods: A total of 246 providers (medical students, psychology trainees, and licensed clinical psychologists) and 98 community members completed an online survey including measures of mental illness stigma and questions regarding a vignette of a person presenting to an emergency department (ER) with primary complaints of pain and a historical schizophrenia diagnosis. The vignette demographics were randomly varied using 2 × 2 × 2 factorial design including race (Black/White), housing status (housed/homeless), and criminal justice history (arrest/no arrest). Results: Providers endorsed mental health stigma at varying levels compared with the community sample, with medical students demonstrating the highest stigma. Prior experience working with psychiatric populations was associated with lower stigma. Providers were more likely to conceptualize homeless ER presentations as potentially due to a lack of resources or substance dependence and were less likely to conceptualize ER presentations with arrest histories as pain related. Homeless vignettes were more likely to be referred for social services and vignettes with arrest histories were less likely to be referred for follow-up pain services. Conclusions and Implications for Practice: Findings suggest that individuals with SMI and additional marginalized identities likely experience exacerbated stigma within treatment settings, and this may also influence treatment decision-making. There is a need to consider intersectionality in future research and interventions for decreasing mental health stigma in healthcare settings.

Correlates of gun violence by criminal justice-involved adolescents.

OBJECTIVE: This study presents a prospective evaluation of the contribution of criminogenic factors, psychiatric symptomatology, and neighborhood-level factors to risk for self-reported gun violence by adolescents with criminal justice involvement. HYPOTHESIS: We hypothesized that elevated psychiatric symptom clusters would be associated with increased risk for gun violence after accounting for criminogenic factors and that neighborhood contextual variables would contribute independently to gun violence risk controlling for criminogenic and psychiatric factors. METHOD: Data were drawn from the Pathways to Desistance study (Mulvey et al., 2004), a previously collected, longitudinal evaluation of 1,354 adolescents with felony or weapons-based misdemeanor convictions. Participants were located in Arizona and Pennsylvania and aged 14-18 at baseline. The majority identified as male (86.4%) and Black (41.4%) or Hispanic (33.5%). Participants completed interviews at baseline and follow-up over 7 years. This study drew indicators of criminogenic factors, psychiatric factors, ratings of neighborhood context, and self-reported offending. We used discrete time survival analysis to prospectively evaluate the contribution of independent variables to time to gun violence. RESULTS: The presence of self-reported threat control override symptoms represented a 56% increase in risk controlling for demographic and criminogenic factors, odds ratio = 1.56, 95% confidence interval [1.11, 2.18]. Ratings of higher neighborhood gun accessibility represented almost 2.5 times increased risk for self-reported gun violence controlling for demographic, criminogenic, and psychiatric factors, odds ratio = 2.48, 95% confidence interval [1.60, 3.85]. CONCLUSIONS: Results suggest that consideration of both environmental and individual-level factors hold importance for management of community risk and public safety for adolescents with criminal justice involvement.

Parvimico materdei gen. et sp. nov.: A new platyrrhine from the Early Miocene of the Amazon Basin, Peru.

Three field seasons of exploration along the Río Alto Madre de Dios in Peruvian Amazonia have yielded a fauna of micromammals from a new locality AMD-45, at ∼12.8°S. So far we have identified the new primate described here as well as small caviomorph rodents, cenolestoid marsupials, interatheriid notoungulates, xenarthrans, fish, lizards and invertebrates. The site is in the Bala Formation as exposed where the river transects a syncline. U-Pb dates on detrital zircons constrain the locality's age at between 17.1 ± 0.7 Ma and 18.9 ± 0.7 Ma, making the fauna age-equivalent to that from the Pinturas Formation and the older parts of the Santa Cruz Formation of Patagonian Argentina (Santacrucian). The primate specimen is an unworn M1 of exceptionally small size (equivalent in size to the extant callitrichine, Callithrix jacchus, among the smallest living platyrrhines and the smallest Eocene-Early Miocene platyrrhine yet recorded). Despite its small size it is unlike extant callitrichines in having a prominent cingulum hypocone. Based on the moderate development of the buccal crests, this animal likely had a diet similar to that of frugivorous callitrichines, and distinctly different from the more similarly-sized gummivores, Cebuella and C. jacchus. The phyletic position of the new taxon is uncertain, especially given the autapomorphic character of the tooth as a whole. Nevertheless, its unusual morphology hints at a wholly original and hitherto unknown Amazonian fauna, and reinforces the impression of the geographic separation of the Amazonian tropics from the more geographically isolated southerly parts of the continent in Early Miocene times.

A randomized-controlled trial of treatment for self-stigma among persons diagnosed with schizophrenia-spectrum disorders.

PURPOSE: A substantial body of research indicates that self-stigma is associated with poorer outcomes related to recovery among people with severe mental illnesses. Narrative Enhancement and Cognitive Therapy (NECT) is a structured, group-based approach which targets the effects of self-stigma. A randomized-controlled trial was conducted to examine the efficacy of NECT. METHODS: One hundred and seventy persons, recruited from both outpatient and comprehensive treatment settings, meeting criteria for schizophrenia-spectrum disorders and moderate-to-elevated self-stigma, were randomly assigned to NECT or supportive group therapy and assessed at four time points over the course of nearly a year. Participants completed measures of self-stigma, hope, self-esteem, functioning, psychiatric symptoms, coping with symptoms, and narrative insight. RESULTS: Analyses indicated that NECT participants in outpatient sites improved significantly more over time in self-stigma compared to supportive group therapy participants in outpatient sites, while NECT participants in comprehensive (including day treatment and psychiatric rehabilitation program) sites improved significantly more in hopelessness and narrative insight than other participants. NECT participants as a group showed decreases in the social withdrawal component of self-stigma, decreased in their use of avoidant coping strategies, and were more engaged in treatment than supportive group therapy participants. There was no evidence for effects of NECT on social functioning or psychiatric symptoms. CONCLUSIONS: Findings suggest that NECT primarily impacts self-stigma and related outcomes, and that the degree of its effects is partially dependent on the treatment context in which it is offered.

Intraspecific variation in semicircular canal morphology-A missing element in adaptive scenarios?

OBJECTIVES: Recent evidence suggests that the amount of intraspecific variation in semicircular canal morphology may, itself, be evidence for varying levels of selection related to locomotor demands. To determine the extent of this phenomenon across taxa, we expand upon previous work by examining intraspecific variation in canal radii and canal orthogonality in a broad sample of strepsirrhine and platyrrhine primates. Patterns of interspecific variation are re-examined in light of intraspecific variation to better understand the resolution at which locomotion can be reconstructed from single individuals. MATERIALS AND METHODS: Data was collected from high-resolution CT scans of 14 size-matched, related species. Six of these taxa have existing data on rotational head speeds. RESULTS: The level of intraspecific variation was found to differ in strepsirrhine and in platyrrhine species pairs, with larger ranges of variation generally observed for the slower moving taxon than the faster moving one. Taxa that are classified as relatively agile can to some extent be separated from those who are slower-moving, but only when comparing similarly sized, closely related species with more extreme forms of locomotion. DISCUSSION: Our findings agree with previous research showing that canal intraspecific variation can fluctuate according to species-specific locomotor behavior and extends this further by identifying behaviors that may be under unusual selective pressure. It also demonstrates the complexity of interpreting inner ear morphology in the context of broadly applicable locomotor "categories" of the kind commonly used in behavioral studies. We suspect that simplified models predicting vestibular sensitivity may be unable to differentiate behaviors when only a single specimen is available.

The Role of Neighborhood Factors and Community Stigma in Predicting Community Participation Among Persons With Psychiatric Disabilities.

OBJECTIVE: This study examined the association between neighborhood characteristics, stigma related to mental illness reported by local community members, and measures of perceived stigma and community participation among individuals with psychiatric disabilities living in independent scattered-site housing or in congregate housing in three neighborhoods in the New York City metropolitan area. METHODS: Neighborhood characteristics were drawn from the 2010 U.S. Census. Surveys focusing on attitudes and intended behavior toward people with mental illness were administered to 608 general community members, and clinical interviews were conducted with 343 persons with psychiatric disabilities. RESULTS: Of neighborhood characteristics, both greater socioeconomic disadvantage and more "suburban values" (lower housing density and greater political conservativism) predicted more perpetrated stigma reported by community members. There was no significant relationship between stigma reported by community members and perceived stigma among participants with psychiatric disabilities. Community stigma predicted vocational involvement and demonstrated interaction effects with housing, such that persons living in congregate housing demonstrated more community participation in communities with more stigma, whereas persons living in scattered-site housing demonstrated less participation in these communities. Perceived stigma was significantly negatively related to community participation. CONCLUSIONS: Findings suggest that effects of neighborhood characteristics and community stigma on people with psychiatric disabilities are complex and are partly conditioned by housing context.
