Suicide attempts among adults denying active suicidal ideation: An examination of the relationship between suicidal thought content and suicidal behavior.

OBJECTIVES: The purpose of the current study was to examine the possibility that there are multiple pathways to suicidal behavior by conducting a fine-grained investigation of the relationship between suicidal thought content and suicidal behavior. METHODS: Six thousand two hundred US adults completed self-report measures of suicidal thoughts and behaviors. Descriptive statistics and logistic regression were used to examine the relationship between suicidal thoughts and behaviors. RESULTS: About 36.0% of participants with a lifetime suicide attempt denied ever experiencing any active suicidal thoughts and 11.0% denied ever experiencing any suicidal thoughts; 53.8% of recent attempters denied recent active suicidal thoughts and 22.6% denied any recent suicidal thoughts. Additionally, the sole presence of passive suicidal ideation was associated with increased odds of lifetime and past-month suicide attempts. CONCLUSIONS: These findings suggest that there are likely multiple pathways to suicide, some of which do not involve progressively worsening suicidal thoughts.

Trajectories of suicidal risk among individuals with first-episode psychosis: Relationship to recovery and symptoms.

This study examined trajectories of suicide-risk and their relationship to symptoms, recovery, and quality of life over time. Data was obtained from the Recovery after an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP) study. 404 individuals with first-episode psychosis (FEP) completed measures of suicide-risk, depression, positive symptoms, recovery, and quality of life at baseline, 6mo, 12mo, 18mo, and 24mo. Latent class analysis was used to identify temporal trajectories of suicide-risk. General linear mixed models for repeated measures were used to examine the relationship between the latent trajectories of suicide-risk and clinical variables. Results identified three latent trajectories of suicide-risk (low-risk, worsening, and improving). The low-risk and improving classes experienced improvements in depression, positive symptoms, quality of life, and recovery over time. The worsening class experienced improvements in positive symptoms and quality of life, but no change in depression or recovery. These results suggest that some individuals with FEP are at risk for persistent depression and worsening suicide-risk during treatment despite experiencing improvements in positive symptoms and quality of life. These findings have important clinical implications, as persistent depression and worsening suicide-risk might be masked by the primary focus on positive symptoms and quality of life in most FEP clinics.

The influence of complex psychiatric comorbidities on treatment for clinical high-risk for psychosis: A preliminary study.

AIM: Despite increasingly refined tools for identifying individuals at clinical high-risk for psychosis (CHR-P), less is known about the effectiveness of CHR-P interventions. The significant clinical heterogeneity among CHR-P individuals suggests that interventions may need to be personalized during this emerging illness phase. We examined longitudinal trajectories within-persons during treatment to investigate whether baseline factors predict symptomatic and functional outcomes. METHOD: A total of 36 CHR-P individuals were rated on attenuated positive symptoms and functioning at baseline and each week during CHR-P step-based treatment. RESULTS: Linear mixed-effects models revealed that attenuated positive symptoms decreased during the study period, while functioning did not significantly change. When examining baseline predictors, a significant group-by-time interaction emerged whereby CHR-P individuals with more psychiatric comorbidities at baseline (indicating greater clinical complexity) improved in functioning during the study period relative to CHR-P individuals with fewer comorbidities. CONCLUSION: Individual differences in clinical complexity may predict functional response during the early phases of CHR-P treatment.

Identification of Psychosis Risk and Diagnosis of First-Episode Psychosis: Advice for Clinicians.

Early detection of psychotic-spectrum disorders among adolescents and young adults is crucial, as the initial years after psychotic symptom onset encompass a critical period in which psychosocial and pharmacological interventions are most effective. Moreover, clinicians and researchers in recent decades have thoroughly characterized psychosis-risk syndromes, in which youth are experiencing early warning signs indicative of heightened risk for developing a psychotic disorder. These insights have created opportunities for intervention even earlier in the illness course, ideally culminating in the prevention or mitigation of psychosis onset. However, identification and diagnosis of early signs of psychosis can be complex, as clinical presentations are heterogeneous, and psychotic symptoms exist on a continuum. When a young person presents to a clinic, it may be unclear whether they are experiencing common, mild psychotic-like symptoms, early warning signs of psychosis, overt psychotic symptoms, or symptoms better accounted for by a non-psychotic disorder. Therefore, the purpose of this review is to provide a framework for clinicians, including those who treat non-psychotic disorders and those in primary care settings, for guiding identification and diagnosis of early psychosis within the presenting clinic or via referral to a specialty clinic. We first provide descriptions and examples of first-episode psychosis (FEP) and psychosis-risk syndromes, as well as assessment tools used to diagnose these conditions. Next, we provide guidance as to the differential diagnosis of conditions which have phenotypic overlap with psychotic disorders, while considering the possibility of co-occurring symptoms in which case transdiagnostic treatments are encouraged. Finally, we conclude with an overview of early detection screening and outreach campaigns, which should be further optimized to reduce the duration of untreated psychosis among youth.

Costs of Coordinated Specialty Care for First-Episode Psychosis: A Microcosting Analysis.

In this study, the authors measured and described the costs of coordinated specialty care (CSC) for first-episode psychosis in Ohio. A microcosting tool was used to estimate personnel and nonpersonnel costs of service delivery at seven CSC programs. Average annual cost per participant (N=511 participants) was estimated as $17,810 (95% CI=$9,141-$26,479). On average, 61% (95% CI=53%-69%) of annual program costs were nonbillable. Key cost drivers included facility costs, administrative tasks, and social services. Novel financing models may redress reimbursement gaps incurred by CSC programs.

An examination of the relationship between positive schizotypy and suicide risk using five distinct samples.

Individuals with schizophrenia are at increased risk for suicide. However, much less is known about suicide risk among individuals with schizotypic features. To address this gap in the literature, the current report examines the relationship between positive schizotypy and suicide risk using five distinct samples. Each of these five studies addresses unique, but complementary, questions regarding the relationship between positive schizotypy and suicide risk. Studies 1 and 2 investigate the cross-sectional relationship between perceptual aberrations and suicidal ideation. Study 3 examines the relationship between suicidal ideation and multiple positive schizotypic features (perceptual aberrations, magical thinking, paranoia, and referential thinking). Study 4 investigates the long-term relationship between perceptual aberrations and suicide risk through a 17-year follow-up. Finally, Study 5 examines the specificity of our findings using a psychiatric control group. Results across all five studies support a relationship between suicide risk and positive schizotypy. Specifically, perceptual aberrations were associated with suicide risk both cross-sectionally and longitudinally. Results also suggest that individuals with positive schizotypic features have rates of suicidal ideation that are comparable to those with high negative affect and are significantly greater than healthy controls. Taken together, these findings establish an empirical connection between positive schizotypy and suicide risk, thus expanding the purview of the suicide risk construct.

Metacognitive Skills Training and Computerized Cognitive Remediation among Individuals with First-Episode Psychosis: Influence on Social Cognition.

Background: Metacognitive skills training (MST) is often integrated into cognitive remediation programs for psychosis. Social cognition - the mental processes underlying social perception and behavior - is robustly related to outcomes in psychosis and is increasingly addressed with targeted treatments. Though metacognition and social cognition are related constructs, little is known about how MST may influence social cognition among individuals with psychosis participating in broad-based, non-social cognitive remediation. Methods: Individuals with first-episode psychosis who completed six months of metacognitive remediation (MCR; n=12) were compared to a historical control group who received six months of computerized cognition remediation (CCR; n=10) alone (ClinicalTrials.gov Identifier NCT01570972). Results: Though individuals receiving MCR experienced gains in emotion processing and theory of mind, these changes were not significantly different when compared to individuals receiving CCR. MST did not contribute to social cognitive change in the context of CCR. Discussion: Though MST may be relevant to facilitating social cognitive gains within broader cognitive remediation programs for first-episode psychosis, these benefits are limited and may not exceed those conferred by standard cognitive remediation. Opportunities for investigation of other potential mechanisms of social cognitive response to interventions remain.

Suicidal thoughts and behaviors among gender and sexual minorities: Adults ages 25-44 show highest rates of past month suicidal thoughts.

INTRODUCTION: Sexual and gender minority (SGM) people are at increased risk for suicidal thoughts and behaviors relative to their cisgender heterosexual peers. However, most research in this area has focused on youth, limiting our understanding of suicide risk among SGM adults. METHODS: To address this gap in the literature, the present study examined suicidal thoughts and behaviors among SGM adults across different age groups using a sample of 10,620 US adults. RESULTS: Consistent with the literature on youth, SGM adults showed higher rates of suicidal thoughts and behaviors than cisgender heterosexual adults. When examining prevalence rates across various age groups, young adults (18-25) showed greater suicidal thoughts and behaviors relative to adults ages 45+. However, adults ages 25-44 actually showed the highest rate of past month suicidal thoughts compared to adults ages 18-25. CONCLUSION: These findings suggest that suicide risk for SGM extends beyond youth and highlights the need for more research on middle-age SGM adults. Additional resources for SGM adults that are not only tailored toward youth and young adults are warranted.

An empirical investigation of the distinction between passive and active ideation: Understanding the latent structure of suicidal thought content.

INTRODUCTION: Although the distinction between passive and active suicidal ideation is well accepted by suicide researchers and clinicians, there has been very little empirical investigation into this distinction. The current study addressed this gap by examining the latent structure of suicidal ideation based on thought content. METHOD: Participants from two distinct samples of U.S. adults (n1 = 6200; n2 = 10,625) completed a self-report assessment of eight commonly experienced suicidal thoughts using the Self-Injurious Thoughts and Behaviors Interview-Revised. Exploratory structural equation modeling was used to examine the latent structure of suicidal thoughts. RESULTS: The two-factor model demonstrated significantly better fit than the one-factor solution across both samples. Thoughts typically classified as passive ideation strongly loaded onto one factor, whereas thoughts typically classified as active ideation loaded onto the second factor. The two factors were highly correlated and some suicidal thoughts exhibited meaningful cross-loading. CONCLUSION: Our results suggest that passive and active ideation are two distinct constructs. Although they often co-occur, passive and active ideation are not nested constructs and should not be viewed as gradients of one underlying construct. Our findings suggest that at a minimum both passive and active ideation should be included in all suicide risk assessments and screenings.

Rapid intensification of suicide risk preceding suicidal behavior among primary care patients.

BACKGROUND: Approximately half of those who attempt suicide report experiencing suicidal ideation and suicidal planning in advance; others deny these experiences. Some researchers have hypothesized that rapid intensification is due to past suicidal ideation and/or behaviors that are "mentally shelved" but remain available for rapid access later. METHOD: To evaluate this hypothesis, we examined (a) temporal sequencing of suicidal ideation, suicidal planning, and suicidal behavior, and (b) speed of emergence of suicidal behavior in a prospective cohort study of 2744 primary care patients. RESULTS: Of 52 patients reporting suicidal behavior during follow-up, 20 (38.5%) reported suicidal ideation and planning prior to their suicidal behavior, 23 (44.2%) reported suicidal ideation but not planning, and nine (17.3%) denied both suicidal ideation and planning. Over half (n = 30, 57.7%) reported the onset of suicidal ideation and/or planning on the same day as or after their suicidal behavior (i.e., rapid intensification). Rapid intensification was not associated with increased likelihood of reporting recent or past suicidal ideation, planning, or behaviors, suggesting rapid intensification does not depend on prior experience with suicidal ideation and/or behaviors. CONCLUSION: Detecting primary care patients at risk for this form of suicidal behavior may be limited even with universal suicide risk screening.

Impact of Treatment Initiation and Engagement on Deliberate Self-Harm Among Individuals With First-Episode Psychosis.

OBJECTIVE: Individuals with psychosis are at increased risk for suicide, with the greatest risk being present during the first few months after diagnosis. The authors aimed to examine whether treatment initiation within 14 days of diagnosis and treatment engagement within 90 days of initiation reduce the risk for deliberate self-harm (DSH) among individuals with first-episode psychosis (FEP). METHODS: A retrospective longitudinal cohort design was adopted by using Ohio Medicaid claims for 6,349 adolescents and young adults ages 15-24 years with FEP. Logistic regression was used to examine factors associated with treatment initiation and engagement. Cox proportional hazard models were used to estimate the impact of treatment initiation and engagement on DSH. Propensity score weighting was used to control for sociodemographic and clinical covariates. RESULTS: Approximately 70% of the sample initiated treatment, 55% of whom engaged in treatment. Treatment initiation and engagement were associated with both demographic and clinical variables. Treatment initiation significantly reduced the hazard of DSH (average treatment effect in the entire population: hazard ratio [HR]=0.62, 95% CI=0.47-0.81; average treatment effect among those treated: HR=0.64, 95% CI=0.52-0.80). In contrast, treatment engagement was not significantly associated with DSH. CONCLUSIONS: These results suggest that the initial treatment contact is essential for reducing DSH among adolescents and young adults with FEP. Additionally, the finding that treatment engagement did not reduce DSH suggests that standard clinical care may not be sufficient for reducing DSH in this population. These findings highlight the need for suicide-specific interventions for individuals with FEP.

Within-Person Relationship between Attenuated Positive Symptoms and Suicidal Ideation among Individuals at Clinical High Risk for Psychosis.

Individuals at clinical high-risk for psychosis (CHR-P) are at increased risk for suicide. However, the relationship between attenuated positive symptoms and suicidal ideation are not well understood, particularly as they interact over time. The current study addressed this gap in the literature. We hypothesized that greater attenuated symptoms would be concurrently and prospectively associated with suicidal ideation. Further, we hypothesized that suspiciousness and perceptual abnormalities would have the strongest relationship with suicidal ideation. Within-person variation in symptoms and suicidal ideation were examined across 24 treatment sessions for individuals at CHR-P. Attenuated positive symptoms (unusual thought content, suspiciousness, grandiose ideas, perceptual abnormalities, and disorganized communication) and suicidal ideation were assessed at each session. Logistic mixed effect models examined concurrent and time-lagged relationships between symptoms and suicidal ideation among 36 individuals at CHR-P. Results indicated that suicidal ideation was more likely during weeks when participants reported more severe total attenuated positive symptoms. Further, suspiciousness was uniquely associated with suicidal ideation, both concurrently and at the following session. Post hoc models examined the reverse direction of this relationship, demonstrating that suicidal ideation also prospectively predicted suspiciousness at the following session. These results suggest that within-person attenuated symptoms, particularly suspiciousness, are associated with suicidal ideation among individuals at CHR-P. However, the bidirectional relationship between suspiciousness and suicidal ideation raises questions about causal nature of this relationship. Further research is needed to examine the dynamic interplay of suspiciousness and suicidal ideation.

Variability in suicidal ideation during treatment for individuals at clinical high risk for psychosis: The importance of repeated assessment.

AIM: Suicide risk is elevated among individuals at clinical high risk for psychosis (CHR-P). The current study examined variability in suicidal ideation during treatment for individuals at CHR-P. METHODS: A retrospective chart review was used to examine the course of suicidal ideation during 16 sessions of individual psychotherapy for 25 individuals at CHR-P. RESULTS: Suicidal ideation was reported by 24% of participants at session 1 and 16% at session 16, with minimal within-subject change in the presence of suicidal ideation across the two time points. However, a more fine-grained investigation at each session indicated that 60% of individuals at CHR-P experienced suicidal ideation at least once during treatment. Additionally, there was great variability in suicidal ideation both within and between participants over the course of the 16 sessions. CONCLUSIONS: These findings highlight the importance of repeated assessment when examining suicidal ideation as a treatment outcome for individuals at CHR-P.

Symptomatic and Functional Outcomes Among Individuals at High Risk for Psychosis Participating in Step-Based Care.

Validated, multicomponent treatments designed to address symptoms and functioning of individuals at clinical high risk for psychosis are currently lacking. The authors report findings of a study with such individuals participating in step-based care-a program designed to provide low-intensity, non-psychosis-specific interventions and advancement to higher-intensity, psychosis-specific interventions only if an individual is not meeting criteria for a clinical response. Among individuals with symptomatic or functional concerns at enrollment, 67% met criteria for a symptomatic response (median time to response=11.1 weeks), and 64% met criteria for a functional response (median time to response=8.9 weeks).

Psychotic experiences, emotion regulation, and suicidal ideation among Chilean adolescents in the general population.

Psychotic experiences are associated with increased risk for suicide. Despite this well-established finding, very little is known about factors that contribute to this relationship. The current study investigated the relationship between psychotic experiences, emotion regulation, and suicidal ideation among 1,590 Chilean adolescents in the general population. Participants completed self-report measures of psychotic experiences (Community Assessment of Psychic Experiences), emotion regulation (Emotion Regulation Questionnaire), depression (Patient Health Questionnaire-9), and suicidal ideation (Columbia Suicide Severity Rating Scale). Statistical analyses included Mann-Whitney U tests, point-biserial correlations, logistic regression, and moderation analyses. Results suggest that paranoid ideation, bizarre experiences, and perceptual abnormalities were moderately associated with suicidal ideation. Additionally, greater expressive suppression and cognitive reappraisal were associated with suicidal ideation. Results from the logistic regression indicate that paranoid ideation, perceptual abnormalities, and expressive suppression have the strongest relationship with suicidal ideation, even when controlling for depression and relevant demographic variables. Additionally, paranoid ideation interacted with expressive suppression to predict suicidal ideation, with expressive suppression having the strongest relationship with suicidal ideation when paranoid ideation was low to moderate. Taken together, these findings support the broader literature suggesting that emotion regulation might be a transdiagnostic risk factor for suicidal ideation. Additional longitudinal research is needed to examine whether expressive suppression and other maladaptive emotion regulation strategies serve as a mechanism for suicidal ideation both in the general population and among individuals with psychotic experiences.

Cognition and suicide risk among individuals with first-episode psychosis: A 6-month follow-up.

Objective: There is emerging evidence that greater cognition is associated with increased risk for suicide among individuals with psychosis. Given this association, concerns have been raised that cognitive interventions might actually increase risk for suicide in this population. Therefore, the present study investigated the cross-sectional and longitudinal relationship between cognition and suicide risk among individuals with first-episode psychosis. Method: Sixty-five participants completed measures of suicide risk, depression, and cognition at baseline and 6 months. Within-subject mediation analysis was used to examine the indirect effect of cognition on suicide risk. Within-subject moderation analysis was used to examine whether participation in cognitive enhancing intervention (e.g., computerized drill-and-practice cognitive remediation and metacognitive remediation therapy) moderated changes in suicide risk. Results: Consistent with prior studies, our cross-sectional results suggest that greater cognition is associated with increased risk for suicide. However, this effect was limited in scope, as we found that verbal learning was the only cognitive domain associated with suicide risk in our sample. Results from our longitudinal analyses show that changes in depressive symptoms, but not changes verbal learning, mediate changes in suicide risk during the first 6 months of treatment. In addition, participation in cognitive enhancing interventions did not moderate changes in suicide risk. Conclusions and Implications for Practice: Our results suggest that cognition is a correlate, or a proxy risk factor, rather than a causal risk factor for suicide. Although these findings contradict previously raised concerns that cognitive interventions might unintentionally increase risk for suicide, ongoing assessment is warranted and additional research is needed.

Improvements in metacognition mediate the effect of metacognitive remediation therapy: A non-randomized controlled study among individuals with first-episode psychosis.

AIM: Metacognitive remediation therapy (MCR) has been shown to help individuals with first-episode psychosis experience improvements in cognition, social functioning, vocational/educational functioning and quality of life. The theoretical model underlying MCR has yet to be empirically validated. METHODS: Seventy-three individuals with first-episode psychosis completed measures of metacognition and cognition at enrollment and after 6-months of care at a specialized clinical program for individuals with first-episode psychosis. Among this group, we compared changes in these variables between the 21 individuals who opted to participate in MCR and the 52 individuals who did not participate in MCR. RESULTS: Improvements in metacognition were moderated by MCR treatment participation. Consistent with the MCR theoretical model of change, increases in metacognition mediated the relationship between treatment and longitudinal changes in cognition. CONCLUSIONS: Our findings suggest that the benefits of MCR on cognitive functioning may stem, in part, from the ability of MCR to produce improvements in metacognitive functioning.

Risk Factors for Deliberate Self-harm and Suicide Among Adolescents and Young Adults With First-Episode Psychosis.

Little is known about the risk factors for deliberate self-harm (DSH) and suicide among adolescents and young adults with first episode psychosis (FEP) and the longitudinal course of DSH following the initial onset of illness. This study identifies risk factors for DSH and suicide death among Medicaid-covered adolescents and young adults with FEP along with the periods of greatest risk for DSH after diagnosis. A retrospective longitudinal cohort analysis was performed using Medicaid claims data merged with death certificate data for 19 422 adolescents and young adults (aged 15-24 years) diagnosed with the onset of FEP between 2010 and 2017. DSH per 1000 person-years and standardized mortality rates for suicide were determined. Hazard ratios of DSH and suicide were estimated by Cox proportional hazard models. During follow-up, 2148 (11.1%) individuals had at least one self-harm event and 22 (0.1%) died by suicide. The hazards of DSH were significantly higher for those with a previous DSH, suicidal ideation, child abuse and neglect, comorbid medical and psychiatric diagnoses, and prior mental health care. The median follow-up time for those who had DSH was 208.0 days (SD: 526.5 days) in adolescents and 108.0 days (SD: 340.0 days) in young adults. Risk of DSH was highest in the first 3 months following FEP. Individuals with FEP are at high risk for self-harm and suicidal behavior, and recognition of who among these individuals and when following illness onset they are at greatest risk may guide more precise clinical recognition and intervention.

Assessment of Latent Subgroups With Suicidal Ideation and Suicidal Behavior Among Gun Owners and Non-Gun Owners in the US.

Importance: Firearm ownership is associated with increased risk for suicide. Objective: To examine patterns of associations among suicidal thoughts and behaviors among gun owners and non-gun owners in the US. Design, Setting, and Participants: In this survey study, cross-sectional online survey data were collected from March to April 2020 from US adults recruited via Qualtrics Panels. Quota sampling was used to approximate US census demographics. Main Outcomes and Measures: The primary outcomes were past-year passive suicidal ideation, active suicidal ideation, suicidal planning, suicidal behaviors, and nonsuicidal self-injury as measured by items from the Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R). Simple latent class analysis (LCA) was used to assign participants to separate classes based on posterior probabilities, and multigroup LCA was used to assess whether the same construct was measured in specified groups. Results: Of 65 079 adults invited to participate, 10 625 (16.3%) completed the survey; 9153 responded "yes" or "no" to the firearm ownership item and were included in the analysis. Of these 9153 respondents (4695 [51.3%] male; mean [SD] age, 46.7 [16.8] years), 2773 (30.3%) reported owning a gun and 6380 (69.7%) reported not owning a gun. Compared with non-gun owners, gun owners were more likely to be male (1779 [64.2%] vs 2916 [45.7%]; χ21, 263.3; P < .001) and White (2090 [75.4%] vs 3945 [61.8%]; χ25, 232.9; P < .001) and to have served in the military (772 [27.8%] vs 609 [9.5%]; χ21, 571.4; P < .001). Five distinct patterns of SITBI-R item endorsement were extracted using simple LCA. Multigroup LCA indicated that the probability of SITBI-R item endorsement differed between gun owners and non-gun owners across subgroups. Among gun owners, the probability of past-month nonfatal suicide attempts was highest in class 4 (ranging from 16.8% for reaching out for help to 27.2% for starting, then changing one's mind). Gun owners in class 4 were characterized by high probabilities of endorsing thoughts about specific ways or methods to attempt suicide (100%) and preparatory behavior (100%). Among non-gun owners, the probability of nonfatal suicide attempts was highest in class 5 (ranging from 14.9% for reaching out for help to 29.7% for starting, then changing one's mind). Non-gun owners in class 5 were characterized by high probabilities of endorsing passive suicidal ideation (84.0%-100%), active suicidal ideation (86.7%-95.0%), and thoughts about specific ways or methods to attempt suicide (97.4%) and a specific place (92.1%) to attempt suicide. Conclusions and Relevance: In this study, in subgroups with lower probabilities of suicide attempt, gun owners and non-gun owners showed similar patterns of suicide risk item endorsement, but when the probability of a suicide attempt increased, gun owners were less likely than non-gun owners to endorse passive and active suicidal ideation. These findings suggest that assessing a broader range of suicide risk indicators may improve risk detection.

Cognitive and Affective Theory of Mind in Positive Schizotypy: Relationship to Schizotypal Traits and Psychosocial Functioning.

Theory of mind (ToM) impairments are well documented in schizophrenia, although it remains unclear whether these deficits exist among individuals with schizotypy. The current study sought to shed light on mixed findings in schizotypy by differentiating between various aspects of ToM, (cognitive/affective ToM and overmentalization/undermentalization). A three-group design (positive schizotypy, negative affect, and healthy control) was used to assess ToM performance on the Movie for Assessment of Social Cognition. Results indicated that the positive schizotypy group made greater intent overmentalization errors than both control groups. The schizotypy and negative affect groups made greater emotion overmentalization errors relative to healthy controls. In addition, the authors explored the relationship between ToM, schizotypal traits, and psychosocial functioning. Results demonstrated a significant positive relationship between cognitive-perceptual schizotypal traits and intent overmentalization as well as a significant positive relationship between interpersonal traits and emotion overmentalization. Finally, intent and emotion overmentalization were both related to poorer psychosocial functioning.
