Predicting psychosis risk using a specific measure of cognitive control: a 12-month longitudinal study.

BACKGROUND: Identifying risk factors of individuals in a clinical-high-risk state for psychosis are vital to prevention and early intervention efforts. Among prodromal abnormalities, cognitive functioning has shown intermediate levels of impairment in CHR relative to first-episode psychosis and healthy controls, highlighting a potential role as a risk factor for transition to psychosis and other negative clinical outcomes. The current study used the AX-CPT, a brief 15-min computerized task, to determine whether cognitive control impairments in CHR at baseline could predict clinical status at 12-month follow-up. METHODS: Baseline AX-CPT data were obtained from 117 CHR individuals participating in two studies, the Early Detection, Intervention, and Prevention of Psychosis Program (EDIPPP) and the Understanding Early Psychosis Programs (EP) and used to predict clinical status at 12-month follow-up. At 12 months, 19 individuals converted to a first episode of psychosis (CHR-C), 52 remitted (CHR-R), and 46 had persistent sub-threshold symptoms (CHR-P). Binary logistic regression and multinomial logistic regression were used to test prediction models. RESULTS: Baseline AX-CPT performance (d-prime context) was less impaired in CHR-R compared to CHR-P and CHR-C patient groups. AX-CPT predictive validity was robust (0.723) for discriminating converters v. non-converters, and even greater (0.771) when predicting CHR three subgroups. CONCLUSIONS: These longitudinal outcome data indicate that cognitive control deficits as measured by AX-CPT d-prime context are a strong predictor of clinical outcome in CHR individuals. The AX-CPT is brief, easily implemented and cost-effective measure that may be valuable for large-scale prediction efforts.

Family Interventions for Schizophrenia and the Psychoses: A Review.

Family psychoeducation as a treatment for schizophrenia was developed 40 years ago almost simultaneously and independently by investigators who at the time were not family therapists. Although the original goal was to decrease high expressed emotion as a means of preventing relapse, later variations have gone beyond to focus on social and role functioning and family well-being. Explicitly disavowing the earlier assumptions that family pathology caused relapse and deterioration, family psychoeducation seeks to engage family members as more sophisticated partners, complementing interventions by clinicians with specialized interactions and coping skills that counter the neurologic deficits inherent to the disorder. It has proved to be one of the most consistently effective treatments available. Reports on outcome studies now number more than 100, while meta-analyses put relapse rate reduction at 50-60% over treatment as usual. The most recent application in first episode and prodromal psychosis, combined with other evidence-based interventions, is yielding perhaps the most promising results yet achieved-substantial return of functioning and avoidance of psychosis altogether. Reviewed here are its scientific, theoretical, and clinical sources, a description of the most commonly applied version-the multifamily group format, selected clinical trials spanning those four decades, international and ethnic adaptations, and studies on mechanisms of efficacy.

Recreational cannabis use over time in individuals at clinical high risk for psychosis: Lack of associations with symptom, neurocognitive, functioning, and treatment patterns.

Recreational cannabis use has recently gained considerable interest as an environmental risk factor that triggers the onset of psychosis. To date, however, the evidence that cannabis is associated with negative outcomes in individuals at clinical high risk (CHR) for psychosis is inconsistent. The present study tracked cannabis usage over a 2-year period and examined its associations with clinical and neurocognitive outcomes, along with medication rates. CHR youth who continuously used cannabis had higher neurocognition and social functioning over time, and decreased medication usage, relative to non-users. Surprisingly, clinical symptoms improved over time despite the medication decreases.

The association between mental health stigma and face emotion recognition in individuals at risk for psychosis.

Self-stigma has been associated with reduced accuracy of face emotion recognition in individuals at clinical high risk for psychosis (CHR). Stigma may also relate to slowing of performance during cognitive tasks for which a negative stereotype is relevant. This study aimed to investigate the association of mental illness stigma with face emotion recognition among CHR individuals. Participants were 143 CHR individuals identified using the Structured Interview for Psychosis-Risk Syndromes (SIPS). Face emotion recognition was assessed using the Penn Emotion Recognition Task (ER-40). Stigma was assessed using discrimination, stereotype awareness, and stereotype agreement subscales of the Mental Health Attitudes Interview for CHR. We tested associations of ER-40 accuracy and response times with these stigma variables, including the role of clinical and demographic factors. Racial/ethnic minoritized participants had higher attenuated positive symptoms than non-minoritized participants. Longer ER-40 response times were correlated with greater stereotype agreement (r=.17, p=.045) and discrimination (r=.22, p=.012). A regression model predicting ER-40 response times revealed an interaction of stereotype agreement with minoritized status (p=.008), with slower response times for minoritized participants as stereotype agreement increased. Greater disorganized symptoms and male gender also predicted longer response times. ER-40 accuracy was not associated with stigma. Overall, minoritized CHR individuals with greater internalized stigma took longer to identify face emotions. Future research is needed to assess whether slower response times are specific to social cues, and if internalized stigma interferes with performance in real-world social situations. Reducing stigma may be an important target for interventions that aim to improve social skills.

Multifamily group psychoeducation and cognitive remediation for first-episode psychosis: a randomized controlled trial.

BACKGROUND: Multifamily group psychoeducation (MFG) has been shown to reduce relapse rates among individuals with first-episode psychosis. However, given the cognitive demands associated with participating in this intervention (e.g., learning and applying a structured problem-solving activity), the cognitive deficits that accompany psychotic disorders may limit the ability of certain individuals to benefit from this intervention. Thus, the goal of this study is to examine whether individuals with first-episode psychosis who participate simultaneously in MFG and cognitive remediation--an intervention shown to improve cognitive functioning among individuals with psychotic disorders--will be less likely to experience a relapse than individuals who participate in MFG alone. METHODS/DESIGN: Forty individuals with first-episode psychosis and their caregiving relative will be recruited to participate in this study. Individuals with first-episode psychosis will be randomized to one of two conditions: (i) MFG with concurrent participation in cognitive remediation or (ii) MFG alone. The primary outcome for this study is relapse of psychotic symptoms. We will also examine secondary outcomes among both individuals with first-episode psychosis (i.e., social and vocational functioning, health-related quality of life, service utilization, independent living status, and cognitive functioning) and their caregiving relatives (i.e., caregiver burden, anxiety, and depression) DISCUSSION: Cognitive remediation offers the possibility of ameliorating a specific deficit (i.e., deficits in cognitive functioning) that often accompanies psychotic symptoms and may restrict the magnitude of the clinical benefits derived from MFG. TRIAL REGISTRATION: ClinicalTrials (NCT): NCT01196286.

Emotional and stigma-related experiences relative to being told one is at risk for psychosis.

OBJECTIVE: Despite the appeal of early intervention in psychosis, there is concern that identifying youth as having high psychosis risk (PR) may trigger stigma. This study employed a pre-post design to measure change in PR participants' emotions about PR upon being told of their PR status and according to whether this was the first time receiving this information. METHODS: Participants (n = 54) identified as at PR via structured interview rated their emotions about PR before and after being told they were at PR. Qualitative analyses explored the valence of participant reflections on being given this information. RESULTS: Participants reported significantly less negative emotion after being told of their PR status (p < .001), regardless of whether they were hearing this for the first time (p = .72). There was no change in positive emotions or the predominant belief that they should keep their PR status private. Most participants commented positively about the process of feedback but negatively about its impact on their self-perceptions and/or expectations of others' perceptions of them. CONCLUSION: This is the first study to collect pre-post data related to being told one is at PR and to examine quantitative and qualitative responses across and within individuals. For a majority of participants, clinical feedback stimulated negative stereotypes even as it relieved some distress. To actively address internalized stigma, clinicians providing feedback to PR youth must attend to the positive and negative impacts on how youth think about themselves as well as how they feel.

Partnering with families: multiple family group psychoeducation for schizophrenia.

Family psychoeducation (FPE) is one of six evidence-based practices endorsed by the Center for Mental Health Services for individuals suffering from chronic mental illnesses. Multiple family group psychoeducation (MFG) has been shown to be an effective component of FPE in reducing symptom relapses and rehospitalizations for individuals with schizophrenia. It is especially effective when family members participate on a consistent basis, which allows them to increase their understanding of the biology of the disorder, learn ways to be supportive, reduce stress in the environment and in their own lives, and develop a broader social network. When used in conjunction with medication, MFG can help an individual with schizophrenia progress towards the rehabilitation phase of recovery. A case illustration describes the engagement of a chronically ill, mid-thirties male in MFG and how his family's participation for 2 years benefits all members, in spite of the longevity of his illness.

Sensory characteristics of youth at clinical high risk for psychosis.

AIM: To identify and compare the sensory characteristics of young people at clinical high risk (CHR) for psychosis to those of peers at clinical low risk (CLR), and to national normative data. CHR and CLR participants were recruited from 6 US regions. METHOD: A descriptive cohort design was used to analyse baseline data collected as part of the Early Detection and Intervention for the Prevention of Psychosis Program (EDIPPP). Raw scores on the Adolescent/Adult Sensory Profile (AASP) were analysed for 205 young people with CHR and 87 with CLR in 2 age groups: 12 to 17 years (N = 203) and 18 to 25 years (N = 89). ANOVA procedures were used to determine whether differences in AASP scores existed across CLR, CHR, and normative groups by age group. RESULTS: CHR participants differed significantly from the normative group for all 4 AASP quadrant scores (Low Registration, Sensory Seeking, Sensory Sensitivity and Sensory Avoiding) in both age groups. CLR participants were similar to norms, except for Sensory Seeking scores that were significantly lower than norms in both age ranges. CONCLUSION: Young people with CHR demonstrate active avoidance, heightened sensitivity, reduced seeking, and reduced registration of sensations in everyday life compared to typical peers. This pattern of differences may be a valuable marker for identifying individuals who are at high risk for developing a psychotic illness, and may also inform interventions designed to prevent or minimize the illness process and accompanying dysfunction.

Impact of "psychosis risk" identification: Examining predictors of how youth view themselves.

BACKGROUND: Identifying young people as at clinical high-risk (CHR) for psychosis affords opportunities for intervention to possibly prevent psychosis onset. Yet such CHR identification could plausibly increase stigma. We do not know whether these youth already perceive themselves to be at psychosis-risk (PR) or how their being told they are at PR might impact how they think about themselves. METHODS: 148 CHR youth were asked about labels they had been given by others (labeling by others) or with which they personally identified (self-labeling). They were then asked which had the greatest impact on how they thought about themselves. We evaluated whether being told vs. thinking they were at PR had stronger effects. FINDINGS: The majority identified nonpsychotic disorders rather than PR labels as having the greatest impact on sense of self (67.6% vs. 27.7%). However, participants who identified themselves as at PR had an 8.8 (95% CI = 2.0-39.1) increase in the odds of the PR label having the greatest impact (p < 0.01). Additionally, having been told by others that they were at PR was associated with a 4.0 increase in odds (95% CI = 1.1-15.0) that the PR label had the most impact (p < 0.05). INTERPRETATION: Nonpsychotic disorder labels appear to have a greater impact on CHR youth than psychosis-risk labels. However, thinking they are at PR, and, secondarily, being told they are at PR, appears to increase the relative impact of the PR label. Understanding self- and other-labeling may be important to how young people think of themselves, and may inform early intervention strategies.

Baseline psychopathology and relationship to longitudinal functional outcome in attenuated and early first episode psychosis.

BACKGROUND: As efforts intensify to intervene early among those at risk for psychosis, examination of the relationship between presenting psychopathology and long-term functional outcome may guide treatment decision-making and offer a means to prevent or reduce chronic disability. METHODS: Data were collected through the Early Detection and Intervention for the Prevention of Psychosis Program (EDIPPP), a multisite national trial testing the efficacy of an early intervention for youth at risk of developing psychosis. Participants were followed prospectively and completed comprehensive evaluations at 6, 12, and 24 months, including the Structured Interview for Prodromal Syndromes (SIPS) and the Global Social and Role Functioning Scales. The present analyses included 327 participants and examined the relationships between baseline symptoms and longitudinal global social and role functioning using a linear mixed modeling approach. RESULTS: Higher baseline negative symptoms and deteriorated thought process predicted worse social and role functioning in the follow-up period. The effect of negative symptoms on social functioning, however, was moderated by positive symptoms, and the relationship between positive symptoms and social functioning changed over time. Baseline positive symptoms, distress, and level of symptom severity were not predictors of either social or role functioning. CONCLUSIONS: Baseline negative symptoms and thought disorder appear to predict functional outcome for up to two years among adolescents and young adults at risk for psychosis. Developing effective interventions to target these symptoms may be critical to promote functional recovery among those experiencing attenuated symptoms or a first episode of psychosis.

The employment intervention demonstration program: major findings and policy implications.

This article summarizes the published results of the Employment Intervention Demonstration Program (EIDP), a federally-funded, multi-site study examining the effectiveness of supported employment programs for 1273 unemployed individuals with psychiatric disabilities in the U.S. Findings confirm the effectiveness of supported employment across different models, program locations, and participant populations. The study's results are discussed in the context of public policies designed to encourage return to work for those with a severe mental illness.

From the psychosis prodrome to the first-episode of psychosis: No evidence of a cognitive decline.

Cognitive deficits have an important role in the neurodevelopment of schizophrenia and other psychotic disorders. However, there is a continuing debate as to whether cognitive impairments in the psychosis prodrome are stable predictors of eventual psychosis or undergo a decline due to the onset of psychosis. In the present study, to determine how cognition changes as illness emerges, we examined baseline neurocognitive performance in a large sample of helping-seeking youth ranging in clinical state from low-risk for psychosis through individuals at clinical high-risk (CHR) for illness to early first-episode patients (EFEP). At baseline, the MATRICS Cognitive Consensus battery was administered to 322 individuals (205 CHRs, 28 EFEPs, and 89 help-seeking controls, HSC) that were part of the larger Early Detection, Intervention and Prevention of Psychosis Program study. CHR individuals were further divided into those who did (CHR-T; n = 12, 6.8%) and did not (CHR-NT, n = 163) convert to psychosis over follow-up (Mean = 99.20 weeks, SD = 21.54). ANCOVAs revealed that there were significant overall group differences (CHR, EFEP, HSC) in processing speed, verbal learning, and overall neurocognition, relative to healthy controls (CNTL). In addition, the CHR-NTs performed similarly to the HSC group, with mild to moderate cognitive deficits relative to the CTRL group. The CHR-Ts mirrored the EFEP group, with large deficits in processing speed, working memory, attention/vigilance, and verbal learning (>1 SD below CNTLs). Interestingly, only verbal learning impairments predicted transition to psychosis, when adjusting for age, education, symptoms, antipsychotic medication, and neurocognitive performance in the other domains. Our findings suggest that large neurocognitive deficits are present prior to illness onset and represent vulnerability markers for psychosis. The results of this study further reinforce that verbal learning should be specifically targeted for preventive intervention for psychosis.

Multifamily group treatment in a program for patients with first-episode psychosis: experiences from the TIPS project.

Psychoeducational multifamily group treatment based on the McFarlane model was implemented for adult patients experiencing a first episode of psychosis and for the families of 301 patients. Patients were participants in a research project in Norway and Denmark. Of 301 patients 246 were invited to participate and 147 agreed. Patients' reluctance to participate increased with age. Most had to wait between six and 12 months until a sufficient number was gathered to start a group. Treatment was well received by patients and families. Care should be taken to prevent a long delay before group commencement at this stressful period in the lives of patients and families.

Factor analysis of the Scale of Prodromal Symptoms: data from the Early Detection and Intervention for the Prevention of Psychosis Program.

AIM: The Scale of Prodromal Symptoms (SOPS) was developed to identify individuals experiencing early signs of psychosis, a critical first step towards early intervention. Preliminary dimension reduction analyses suggested that psychosis-risk symptoms may deviate from the traditional symptom structure of schizophrenia, but findings have been inconsistent. This study investigated the phenomenology of psychosis risk symptoms in a large sample from a multi-site, national study using rigorous factor analysis procedure. METHODS: Participants were 334 help-seeking youth (age: 17.0 ± 3.3) from the Early Detection and Intervention for the Prevention of Psychosis Program, consisting of 203 participants at clinically higher risk (sum of P scores ≥ 7), 87 with clinically lower risk (sum of P scores < 7) and 44 in very early first-episode psychosis (<30 days of positive symptoms). Baseline SOPS data were subjected to principal axis factoring (PAF), estimating factors based on shared variance, with Oblimin rotation. RESULTS: PAF yielded four latent factors explaining 36.1% of total variance: positive symptoms; distress; negative symptoms; and deteriorated thought process. They showed reasonable internal consistency and good convergence validity, and were not orthogonal. CONCLUSIONS: The empirical factors of the SOPS showed similarities and notable differences compared with the existing SOPS structure. Regrouping the symptoms based on the empirical symptom dimensions may improve the diagnostic validity of the SOPS. Relative prominence of the factors and symptom frequency support early identification strategies focusing on positive symptoms and distress. Future investigation of long-term functional implications of these symptom factors may further inform intervention strategies.

Results of a multisite randomized trial of supported employment interventions for individuals with severe mental illness.

CONTEXT: National probability surveys indicate that most individuals with schizophrenia and other severe mental illnesses are not employed. This multisite study tested the effectiveness of supported employment (SE) models combining clinical and vocational rehabilitation services to establish competitive employment. METHODS: We randomly assigned 1273 outpatients with severe mental illness from 7 states in the United States to an experimental SE program or to a comparison or a services-as-usual condition, with follow-up for 24 months. Participants were interviewed semiannually, paid employment was tracked weekly, and vocational and clinical services were measured monthly. Mixed-effects random regression analysis was used to predict the likelihood of competitive employment, working 40 or more hours in a given month, and monthly earnings. RESULTS: Cumulative results during 24 months show that experimental group participants (359/648 [55%]) were more likely than those in the comparison programs (210/625 [34%]) to achieve competitive employment (chi(2) = 61.17; P<.001). Similarly, patients in experimental group programs (330/648 [51%]) were more likely than those in comparison programs (245/625 [39%]) to work 40 or more hours in a given month (chi(2) = 17.66; P<.001). Finally, participants in experimental group programs had significantly higher monthly earnings than those in the comparison programs (mean, US 122 dollars/mo [n=639] vs US 99 dollars/mo [n=622]); t(1259) = -2.04; P<.05). In the multivariate longitudinal analysis, experimental condition subjects were more likely than comparison group subjects to be competitively employed, work 40 or more hours in a given month, and have higher earnings, despite controlling for demographic, clinical, work history, disability beneficiary status, and study site confounders. Moreover, the advantage of experimental over comparison group participants increased during the 24-month study period. CONCLUSION: The SE models tailored by integrating clinical and vocational services were more effective than services as usual or unenhanced services.

Estimated payments to employment service providers for persons with mental illness in the Ticket to Work program.

OBJECTIVE: The Ticket to Work and Work Incentives Improvement Act of 1999 removes work disincentives and promotes access to vocational services for people with disabilities. This study calculated the amount of payments that would have been made to employment service providers if study participants had been enrolled in the Ticket program. METHODS: Data were from 450 Social Security Disability Insurance beneficiaries with psychiatric disabilities enrolled in a multisite study of supported employment. Earnings over two years were used to calculate provider payments under two reimbursement formulas used in the Ticket program. RESULTS: Only a quarter of service recipients (26 percent) reached earnings levels that would have triggered provider payments under the first reimbursement formula. Only 4 percent would have completed their trial work period and left the rolls, generating payments under the second formula. CONCLUSIONS: The current provider payment systems of the Ticket to Work program do not reflect the reality of rehabilitation for individuals with severe mental illness. Reforms should take into account outcomes of return-to-work services for this population.

Personalized Prediction of Psychosis: External Validation of the NAPLS-2 Psychosis Risk Calculator With the EDIPPP Project.

OBJECTIVE: As part of the second phase of the North American Prodrome Longitudinal Study (NAPLS-2), Cannon and colleagues report, concurrently with the present article, on a risk calculator for the individualized prediction of a psychotic disorder in a 2-year period. The present study represents an external validation of the NAPLS-2 psychosis risk calculator using an independent sample of patients at clinical high risk for psychosis collected as part of the Early Detection, Intervention, and Prevention of Psychosis Program (EDIPPP). METHOD: Of the total EDIPPP sample of 210 subjects rated as being at clinical high risk based on the Structured Interview for Prodromal Syndromes, 176 had at least one follow-up assessment and were included in the construction of a new prediction model with six predictor variables in the NAPLS-2 psychosis risk calculator (unusual thoughts and suspiciousness, symbol coding test performance, verbal learning test performance, decline in social functioning, baseline age, and family history). Discrimination performance was assessed with the area under the receiver operating characteristic curve (AUC). The NAPLS-2 risk calculator was then used to generate a psychosis risk estimate for each case in the external validation sample. RESULTS: The external validation model showed good discrimination, with an AUC of 0.790 (95% CI=0.644-0.937). In addition, the personalized risk generated by the risk calculator provided a solid estimation of the actual conversion outcome in the validation sample. CONCLUSIONS: Two independent samples of clinical high-risk patients converge to validate the NAPLS-2 psychosis risk calculator. This prediction calculator represents a meaningful step toward early intervention and the personalized treatment of psychotic disorders.

Early Detection, Intervention and Prevention of Psychosis Program: Community Outreach and Early Identification at Six U.S. Sites.

OBJECTIVE: This study assessed the effects of a community outreach and education model implemented as part of the Early Detection, Intervention and Prevention of Psychosis Program (EDIPPP), a national multisite study in six U.S. regions. METHODS: EDIPPP's model was designed to generate rapid referrals of youths at clinical high risk of psychosis by creating a network of professionals and community members trained to identify signs of early psychosis. Qualitative and quantitative data were gathered through an evaluation of outreach efforts at five sites over a two-year period and through interviews with staff at all six sites. All outreach activities to groups (educational, medical, and mental health professionals; community groups; media; youth and parent groups; and multicultural communities) were counted for the six sites to determine correlations with total referrals and enrollments. RESULTS: During the study period (May 2007-May 2010), 848 formal presentations were made to 22,840 attendees and 145 informal presentations were made to 11,528 attendees at all six sites. These presentations led to 1,652 phone referrals. A total of 520 (31%) of these individuals were offered in-person orientation, and 392 (75%) of those were assessed for eligibility. A total of 337 individuals (86% of those assessed) met criteria for assignment to the EDIPPP study. CONCLUSIONS: EDIPPP's outreach and education model demonstrated the effectiveness of following a protocol-defined outreach strategy combined with flexibility to reach culturally diverse audiences or initially inaccessible systems. All EDIPPP sites yielded appropriate referrals of youths at risk of psychosis.

Integration of psychiatric and vocational services: a multisite randomized, controlled trial of supported employment.

OBJECTIVE: Although large-scale surveys indicate that patients with severe mental illness want to work, their unemployment rate is three to five times that of the general adult population. This multisite, randomized implementation effectiveness trial examined the impact of highly integrated psychiatric and vocational rehabilitation services on the likelihood of successful work outcomes. METHOD: At seven sites nationwide, 1,273 outpatients with severe mental illness were randomly assigned either to an experimental supported employment program or to a comparison/services-as-usual condition and followed for 24 months. Data collection involved monthly services tracking, semiannual in-person interviews, recording of all paid employment, and program ratings made by using a services-integration measure. The likelihood of competitive employment and working 40 or more hours per month was examined by using mixed-effects random regression analysis. RESULTS: Subjects served by models that integrated psychiatric and vocational service delivery were more than twice as likely to be competitively employed and almost 1(1/2) times as likely to work at least 40 hours per month when the authors controlled for time, demographic, clinical, and work history confounds. In addition, higher cumulative amounts of vocational services were associated with better employment outcomes, whereas higher cumulative amounts of psychiatric services were associated with poorer outcomes. CONCLUSIONS: Supported employment models with high levels of integration of psychiatric and vocational services were more effective than models with low levels of service integration.
