RESUMEN

The prediction error account of delusions has had success. However, its explanation of delusions with different contents has been lacking. Persecutory delusions and paranoia are the common unfounded beliefs that others have harmful intentions towards us. Other delusions include believing that one's thoughts or actions are under external control, or that events in the world have specific personal meaning. We compare learning on two different cognitive tasks, probabilistic reversal learning (PRL) and Kamin blocking, that have relationships to paranoid and non-paranoid delusion-like beliefs, respectively. We find that Clinical High-Risk status alone does not result in different behavioral results on the PRL task but that an individual's level of paranoia is associated with excessive switching behavior. During the Kamin blocking task, paranoid individuals learned inappropriately about the blocked cue. However, they also had decreased learning about the control cue, suggesting more general learning impairments. Non-paranoid delusion-like belief conviction (but not paranoia) was associated with aberrant learning about the blocked cue but intact learning about the control cue, suggesting specific impairments in learning related to cue combination. We fit task-specific computational models separately to behavioral data to explore how latent parameters vary within individuals between tasks, and how they can explain symptom-specific effects. We find that paranoia is associated with low learning rates on the PRL task as well as the blocking task. Non-paranoid delusion-like belief conviction was instead related to parameters controlling the degree and direction of similarity between cue updating during simultaneous cue presentation. These results suggest that paranoia and other delusion-like beliefs involve dissociable deficits in learning and belief updating, which - given the transdiagnostic status of paranoia - may have differential utility in predicting psychosis.

RESUMEN

BACKGROUND: Evidence suggests that both childhood trauma and perceived stress are risk factors for the development of psychosis, as well as negative symptoms such as anhedonia. Previous findings link increases in perceived stress to anhedonia in individuals at clinical high risk for psychosis (CHR) and depression; however, the role of childhood trauma in this relationship has not yet been explored, despite consistent evidence that it is associated with sensitisation to later stress. AIMS: To examine whether perceived stress mediates the relationship between childhood trauma and anhedonia in a group of youth at CHR as well as in controls (groups with depression and with no diagnosed mental health concerns). METHOD: The study used multigroup mediation to examine the indirect effects of childhood trauma on anhedonia via perceived stress in CHR (n = 117) and depression groups (n = 284) and non-psychiatric controls (n = 124). RESULTS: Perceived stress mediated the relationship between childhood trauma and consummatory anhedonia regardless of group status. Perceived stress mediated the relationship between childhood trauma and anticipatory anhedonia for the CHR and depression groups, but not for non-psychiatric controls. Further, groups differed in the magnitude of this relationship, with the effects trending towards stronger for those in the CHR group. CONCLUSIONS: Our findings suggest a potential transdiagnostic pathway through which childhood trauma contributes to anhedonia across severe mental illness.

RESUMEN

INTRODUCTION: Paranoia is a common and impairing psychosis symptom, which exists along a severity continuum that extends into the general population. Individuals at clinical high-risk for psychosis (CHR) frequently experience paranoia and this may elevate their risk for developing full psychosis. Nonetheless, limited work has examined the efficient measurement of paranoia in CHR individuals. The present study aimed to validate an often-used self-report measure, the revised green paranoid thoughts scale (RGPTS), in this critical population. METHOD: Participants were CHR individuals (n = 103), mixed clinical controls (n = 80), and healthy controls (n = 71) who completed self-report and interview measures. Confirmatory factor analysis (CFA), psychometric indices, group differences, and relations to external measures were used to evaluate the reliability and validity of the RGPTS. RESULTS: CFA replicated a two-factor structure for the RGPTS and the associated reference and persecution scales were reliable. CHR individuals scored significantly higher on both reference and persecution, relative to both healthy (ds = 1.03, 0.86) and clinical controls (ds = 0.64, 0.73). In CHR participants, correlations between reference and persecution and external measures were smaller than expected, though showed evidence of discriminant validity (e.g., interviewer-rated paranoia, r = 0.24). When examined in the full sample, correlation magnitude was larger and follow-up analyses indicated that reference related most specifically to paranoia (ß = 0.32), whereas persecution uniquely related to poor social functioning (ß = -0.29). CONCLUSION: These results demonstrate the reliability and validity of the RGPTS, though its scales related more weakly to severity in CHR individuals. The RGPTS may be useful in future work aiming to develop symptom-specific models of emerging paranoia in CHR individuals.

RESUMEN

Objective: Racial inequities in mental health care utilization (MHCU) are well documented. Marginalized racial groups are more likely to report psychosis-like experiences (PLEs) and are at elevated risk for racial discrimination and trauma, impacting PLE severity. Little is known about how factors associated with race impact treatment seeking among individuals reporting PLEs. The present study examined associations between race, trauma, discrimination, PLEs, and MHCU among people endorsing high levels of PLEs. Method: Participants were Asian/Asian American, Black/African American, or White/European American college students ages 18-25 years meeting PLE self-report measure cutoff scores (N = 177). Binary logistic and multiple linear regressions were used to examine associations between past, current, and prospective MHCU and race, potentially traumatic events, discrimination, and PLEs. Results: Participants endorsing more PLEs were more likely to report past and current treatment and to be considering future services. Asian/Asian American and Black/African American participants were less likely to endorse past, current, and prospective future mental health care. Potentially traumatic events predicted increased utilization of past treatment. Conclusions: Results suggest service differences among participants, such that Black/African American and Asian/Asian American young adults reporting PLEs were less likely than White/European American counterparts to seek treatment even when accounting for traumatic events and discrimination. These findings highlight the need to further elucidate MHCU among marginalized racial groups experiencing psychosis-like symptoms. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

Evidence supports the use of brief psychosis-spectrum screening tools for identifying individuals at an increased risk of developing a psychotic disorder. Screening has not been well studied in general mental health settings that serve young adults in the age range associated with highest risk for psychosis. This study explored the feasibility of psychosis-risk screening and assessment among help-seeking students at a university counseling center. The PRIME Screen-Revised was administered to students at clinic intake. Participants who screened positively were offered a follow-up assessment using the Structured Interview for Psychosis-risk Syndromes (SIPS). At intake, 510 students completed the PRIME Screen-Revised, with 132 (25.9%) screening positive. Comprehensive psychosis-spectrum evaluations were completed with 38 participants, and 22 met criteria for a psychosis-spectrum disorder, representing 57.9% of this subsample. Findings suggest that psychosis-risk screening in a college clinic is a promising approach to identifying those at high risk for or in the early stages of psychosis.

RESUMEN

Early detection and prevention of psychosis has become an international priority. Much of this work has focused on youth presenting with attenuated symptoms of psychosis-those at Clinical High Risk for psychosis (CHR)-given their elevated probability of developing the full disorder in subsequent years. Individuals at CHR may be prone to exacerbated psychological distress during the COVID-19 pandemic and its subsequent physical isolation measures, due to heightened stress sensitivity and comorbid mental health problems. Telepsychotherapy holds promise for reaching this population, especially during the current COVID-19 outbreak. However, there are limited evidence-based guidelines or interventions for use of telepsychotherapy with this population. In this paper, we review common clinical issues for individuals at CHR and how they might be exacerbated by the COVID-19 pandemic; best practices for treatment and adaptations for telepsychotherapy for individuals at CHR; and highlight real clinical issues that we are currently experiencing in a United States-based specialized CHR clinic as we conduct telepsychotherapy via videoconferencing. We conclude with questions for those in the field to contemplate, as well as potential challenges and benefits in using telepsychotherapy with individuals at CHR and their families.

RESUMEN

Objective: Anxiety and depression commonly co-occur with substance use disorders. Conceptual models would presume that changes in anxiety and depression should lead to changes in drug and alcohol craving during treatment for co-occurring disorders, but no longitudinal investigation has explored this assumption. This study examined the associations among craving, anxiety, and depression in a dual diagnosis program. Methods: In all, 93 adult patients at a community-based dual diagnosis program for substance use disorders and comorbid anxiety and mood disorders provided daily ratings of anxiety and depression. We examined whether these ratings predicted changes in craving and vice versa. Results: Using hierarchical linear modeling to examine day-to-day change over time, we observed that anxiety and depression ratings uniquely and independently predicted subsequent craving ratings, and craving ratings also predicted subsequent anxiety and depression ratings. Conclusions: These preliminary findings support mutual maintenance models of substance use and psychiatric comorbidity, thus providing preliminary support for integrated programs that simultaneously address both problems. Implications and future directions are discussed.

RESUMEN

Community-partnered school behavioral health (CP-SBH) is a model whereby schools partner with local community agencies to deliver services. This mixed-methods study examined 80 CP-SBH clinicians' adoption and implementation of evidence-based practice (EBP) approaches following mandated training. Forty-four clinicians were randomly assigned to one of two training conditions for a modular common elements approach to EBPs; 36 clinicians were preselected for training in a non-modular EBP. EBP knowledge improved for all training conditions at 8-month follow-up and practice element familiarity improved for modular approach training conditions, but the modular condition including ongoing consultation did not yield better results. Qualitative interviews (N = 17) highlighted multi-level influences of the CP-SBH service system and individual clinician characteristics on adoption and implementation.

RESUMEN

Several neurological variables have been investigated as premorbid biomarkers of vulnerability for schizophrenia and other related disorders. The current study examined whether childhood dyspraxia predicted later adult nonaffective-psychosis-spectrum disorders. From a standardized neurological examination performed with children (aged 10-13) at genetic high risk of schizophrenia and controls, several measures of dyspraxia were used to create a scale composed of face/head dyspraxia, oral articulation, ideomotor dyspraxia (clumsiness), and dressing dyspraxia (n = 244). Multinomial logistic regression showed higher scores on the dyspraxia scale predict nonaffective-psychosis-spectrum disorders relative to other psychiatric disorders and no mental illness outcomes, even after controlling for genetic risk, χ2 (4, 244) = 18.61, p < .001. Findings that symptoms of dyspraxia in childhood (reflecting abnormalities spanning functionally distinct brain networks) specifically predict adult nonaffective-psychosis-spectrum disorders are consistent with a theory of abnormal connectivity, and they highlight a marked early-stage vulnerability in the pathophysiology of nonaffective-psychosis-spectrum disorders.

RESUMEN

Early identification efforts for psychosis have thus far yielded many more individuals "at risk" than actually develop psychotic illness. Here, we test whether measures of reinforcement learning (RL), known to be impaired in chronic schizophrenia, are related to the severity of clinical risk symptoms. Because of the reliance of RL on dopamine-rich frontostriatal systems and evidence of dopamine system dysfunction in the psychosis prodrome, RL measures are of specific interest in this clinical population. The current study examines relationships between psychosis risk symptoms and RL task performance in a sample of adolescents and young adults (n = 70) receiving mental health services. We observed significant correlations between multiple measures of RL performance and measures of both positive and negative symptoms. These results suggest that RL measures may provide a psychosis risk signal in treatment-seeking youth. Further research is necessary to understand the potential predictive role of RL measures for conversion to psychosis.

RESUMEN

Youth and young adults at clinical high risk (CHR) for psychosis experience a broad range of difficulties, including attenuated psychotic symptoms, comorbid concerns, functional impairments, and family and interpersonal stress. Given emerging evidence that early interventions may improve functioning and reduce symptomatology while also lowering risk of transition to full-threshold psychosis, several randomized controlled trials have systematically evaluated the efficacy of CHR treatment approaches. This article describes and summarizes psychosocial intervention approaches that have demonstrated efficacy in treating people at CHR, with a focus on distilling individual components of these treatments. On the basis of the existing literature, we propose an empirically based, flexible, and comprehensive modularized approach to early intervention that meets the varying needs of individuals experiencing CHR-related distress and dysfunction, many of whom may be on a trajectory toward psychosis.

RESUMEN

The Patient Protection and Affordable Care Act focuses on improving consumer engagement and patient-centered care. This article describes the design and rationale of a study targeting family engagement in pediatric mental health services. The study is a 90-day randomized trial of a telephone-delivered Family Navigator services versus usual care for parents of Medicaid-insured youth younger than 13 years with serious mental illness. Youth are identified through a pediatric antipsychotic medication preauthorization program. Family Navigators offer peer support to empower and engage parents in their child's recovery. Outcomes include parent report of empowerment, social support, satisfaction with child mental health services, and child functioning as well as claims-based measures of psychotherapy service utilization and antipsychotic medication dosage. The focus on "family-centered" care in this study is strongly supported by the active role of consumers in study design and implementation.

RESUMEN

PURPOSE: Psychotic experiences and suicidal behavior commonly co-occur in the general population, which can have implications for suicide prevention approaches. However, little is known about the nature of this relation in non-clinical samples. This cross-sectional study aimed to address a research gap by testing whether the relation between psychotic experiences and suicide-related outcomes (ideation, intent, and attempts) is explained by common social and psychological factors. METHODS: Young adult college students (N = 590) were assessed for psychotic experiences, suicidal behavior, and a comprehensive set of 24 potential shared risk factors selected through review of past epidemiological studies and meta-analyses. Nonparametric bootstrapped regression models were used to examine whether these factors attenuated or eliminated the associations between psychotic experiences and suicide-related outcomes. RESULTS: Psychotic experiences were associated with greater risk for suicidal ideation and behaviors. Adjustment for psychosocial factors, particularly those contributing to cumulative stress, accounted for the associations between psychotic experiences and suicide-related outcomes, except broadly defined suicidal ideation. CONCLUSIONS: These results suggest that the robust associations between psychotic experiences and suicidal behavior demonstrated in past studies may be primarily explained by shared risk factors, rather than by causal relations. In our sample, suicidal behavior and sub-threshold psychosis appear to be trans diagnostic clinical outcomes that share common causes, notably cumulative stress, but do not cause one another.

RESUMEN

Family members of consumers with mental illness often play important roles in initiating and supporting treatment. Self-help programs such as the National Alliance on Mental Illness (NAMI) Family-to-Family Education Program (FTF) have been shown to provide a variety of benefits for family members. Despite recognizing the benefits of FTF, little is known about who may benefit most, and in what ways they might benefit. One group of interest is family members of younger consumers, a group shown to report more negative caregiving experiences and more depression and anxiety than caregivers of older consumers. The current study assesses whether relatives of youth (ages 8-18) differ in their response to FTF as opposed to relatives of adults (19 years and older). Results suggest that all members benefit from FTF. Family members of youth in FTF, however, reported gains more pronounced on their depressive symptoms, and negative perceptions and experiences, relative to family members of adults. The importance of peer support programs is discussed, as well as the specific usefulness of these programs to effectively address concerns of relatives of youth with serious mental health concerns.

RESUMEN

Families play an important role in the lives of individuals with mental illness. Coping with the strain of shifting roles and multiple challenges of caregiving can have a huge impact. Limited information exists regarding race-related differences in families' caregiving experiences, their abilities to cope with the mental illness of a loved one, or their interactions with mental health service systems. This study examined race-related differences in the experiences of adults seeking to participate in the National Alliance on Mental Illness Family-to-Family Education Program due to mental illness of a loved one. Participants were 293 White and 107 African American family members who completed measures of problem- and emotion-focused coping, knowledge about mental illness, subjective illness burden, psychological distress, and family functioning. Multiple regression analyses were used to determine race-related differences. African American caregivers reported higher levels of negative caregiving experiences, less knowledge of mental illness, and higher levels of both problem-solving coping and emotion-focused coping, than White caregivers. Mental health programs serving African American families should consider targeting specific strategies to address caregiving challenges, support their use of existing coping mechanisms and support networks, and increase their knowledge of mental illness.

RESUMEN

UNLABELLED: Abstract Background: Public perception of the link between schizophrenia and violence is exaggerated, and interventions are emerging that attempt to educate the public about the actual relationship between violence and schizophrenia. The effectiveness of programs targeting this dangerousness stereotype is unknown, however, as existing instruments do not capture a complete, unbiased picture of stigma. AIMS: To report on the properties of the Brief Implicit Association Test-Schizophrenia Danger (BIAT-SD), which we developed to capture the implicit perception that people with schizophrenia are dangerous. METHODS: We used a multi-trait, multi-method protocol to validate the BIAT-SD based on convergent and discriminant data from undergraduates (n = 97) at baseline and 4-weeks. RESULTS: Preliminary evidence was found for construct validity, internal consistency, and 30-min retest stability. CONCLUSIONS: Potential benefits and implications of the measure to improving the accuracy of stigma measurement are discussed.

RESUMEN

OBJECTIVE: Previous work has found increased endorsement of psychotic-like experiences (PLEs) among marginalized racial and ethnic groups. According to social determinants frameworks, marginalized groups are at increased risk for exposure to socio-environmental risk factors, including systemic factors (eg, poverty and poor housing conditions) and social stressors (eg, discrimination). We examine the extent to which environmental risk factors and stress account for associations between racial/ethnic groups with PLEs. METHOD: Analyses included 11,876 young adolescents 9 to 10 years of age from the Adolescent Brain Cognitive Development (ABCD) study. Mediation models assessed whether stress at 1-year follow-up indirectly linked baseline environmental risk to later distressing PLEs at 2-year follow-up. Serial mediation models examined whether environmental risk and stress indirectly accounted for variation among racial/ethnic groups in self-reported distressing PLEs. RESULTS: Through principal component and mediation analyses, we found evidence that the link between environmental risk (eg, poverty and exposure to crime) and distressing PLEs was mediated by stress. There was also evidence that higher endorsement of distressing PLEs within the Black and Hispanic groups was serially mediated by greater environmental risk and greater stress. CONCLUSION: The analyses provide evidence that the associations between marginalized racial and ethnic identities with the endorsement of PLEs partially reflects the sequelae of systemic socio-environmental factors. Findings suggest the potential for intervening upon environmental risk factors to target the reduction of cumulative stress over time, which may in turn buffer against the development of PLEs. DIVERSITY INCLUSION STATEMENT: We worked to ensure sex and gender balance in the recruitment of human participants.

RESUMEN

Clinical high risk for psychosis (CHR) is a transdiagnostic risk state. However, it is unclear how risk states such as CHR fit within broad transdiagnostic models such as the Hierarchical Taxonomy of Psychopathology (HiTOP). In this study, a hierarchical dimensional symptom structure was defined by unfolding factor analysis of self-report data from 3,460 young adults (mage=20.3). A subsample (n=436) completed clinical interviews, 85 of whom met CHR criteria. Regression models examined relationships between symptom dimensions, CHR status, and clinician-rated symptoms. CHR status was best explained by a reality distortion dimension, with contributions from internalizing dimensions. Positive and negative attenuated psychotic symptoms were best explained by multiple psychotic and nonpsychotic symptom dimensions including reality distortion, distress, fear, detachment, and mania. Attenuated psychotic symptoms are a complex presenting problem warranting comprehensive assessment. HiTOP can provide both diagnostic precision and broad transdiagnostic coverage, making it a valuable resource for use with at-risk individuals.

RESUMEN

AIM: Black individuals in the Unites States endure compounded and unique experiences of discrimination and structural racism that may not be as overtly evident in other countries. These distinctive forms of discrimination and racism can impact the mental health of Black individuals in the Unites States, in this case, their risk for psychosis. Adolescence and early adulthood are vulnerable periods in life where mental illness typically begins to manifest. Understanding the factors contributing to an increased likelihood of specific mental illnesses, such as psychosis, among youth in these vulnerable periods can inform intervention development. This is particularly important for those from minoritized backgrounds Unites States; this group is especially important to study given that Black American youth tend to experience higher psychosis rates and different symptom presentations than non-Black groups. METHODS: This study examined the associations between perceived family support, a critical environmental factor known to be associated with full-psychosis, and attenuated positive symptoms and distress levels in a sample of 155 Black students from a Historically Black College and University (HBCU). Participants completed the Prodromal Questionnaire-Brief that assessed psychosis risk and the Family Environment Scale that assessed three dimensions of family support (family cohesion, expressiveness, and conflict). RESULTS AND CONCLUSION: Positive symptom intensity (r = .30, p < .001) and distress (r = .34, p < .001) were significantly associated with higher family conflict for Black individuals in the Unites States. The findings inform novel intervention targets for psychoeducation and family therapy that have potential to reduce psychosis risk.

RESUMEN

Existing work indicates that there is unmet need for care in those at clinical high risk (CHR) for psychosis. However, research on the factors that drive treatment seeking behaviors in this population is limited. Further, it is unknown how help-seeking behavior in CHR individuals compares to those seen in mood disorders, who have a higher rate of treatment seeking behavior. Participants (n = 559) completed an assessment of their intent to seek mental health treatment, attenuated psychosis-risk symptoms, and psychiatric symptoms and diagnoses. Participants were divided into CHR (n = 91), Mood Disorders (MD) (n = 72), or Community Controls (CC) groups (n = 396), whose intent to seek treatment was compared. Associations between intent to seek treatment with past treatment, depression, anxiety, positive and negative symptoms, distress from symptoms, intelligence quotient (IQ) estimates, and insight were assessed in CHR individuals. Further, it was assessed how this differs for the MD group. The MD group reported higher intent to seek treatment than CHR individuals, which reported higher intent to seek treatment than the CC group. In those at CHR, previous treatment, greater depression and anxiety severity, and higher distress all independently predicted higher intent to seek treatment. Depression predicted intent to seek treatment in both MD and CHR individuals. Previous treatment predicted intent to seek treatment in those at CHR. Our findings suggest that depression and past treatment utilization are critical factors in increasing intent to seek treatment in those at CHR, potentially serving as important targets for engaging this population in treatment.
