Psychotherapy for adolescents and young adults at high risk for psychosis: a systematic review

Assessing the impact of psychiatric genetic counseling on psychiatric hospitalizations

Psychiatric genetic counseling (pGC) can improve patient empowerment and self-efficacy. We explored the relationship between pGC and psychiatric hospitalizations, for which no prior data exist. Using Population Data BC (a provincial dataset), we tested two hypotheses: (1) among patients (>18 years) with psychiatric conditions who received pGC between May 2010 and Dec 2016 (N = 387), compared with the year pre-pGC, in the year post-pGC there would be fewer (a) individuals hospitalized and (b) total hospital admissions; and (2) using a matched cohort design, compared with controls (N = 363, matched 1:4 for sex, diagnosis, time since diagnosis, region, and age, and assigned a pseudo pGC index date), the pGC cohort (N = 91) would have (a) more individuals whose number of hospitalizations decreased and (b) fewer hospitalizations post-pGC/pseudo-index. We also explored total days in hospital. Within the pGC cohort, there were fewer hospitalizations post-pGC than pre- pGC (p = 0.011, OR = 1.69), and total days in hospital decreased (1085 to 669). However, when compared to matched controls, the post-pGC/pseudo index change in hospitalizations among pGC cases was not statistically significant, even after controlling for the higher number of hospitalizations prior. pGC may lead to fewer psychiatric hospitalizations and cost savings; further studies exploring this are warranted.

A Recovery-Oriented Approach: Application of Metacognitive Reflection and Insight Therapy (MERIT) for Youth with Clinical High Risk (CHR) for Psychosis

Clinical High Risk for psychosis (CHR) refers to a phase of heightened risk for developing overt psychosis. CHR often emerges during adolescence or early adulthood. CHR has been identified as a group to target for intervention, with the hope that early intervention can both stave off prolonged suffering and intervene before mental health challenges become part of an individual's identity. However, there are few treatment modalities that can address some of the specific needs of CHR. Metacognitive Reflection and Insight Therapy (MERIT) is an integrative psychotherapy that can be applied to the CHR population. MERIT offers unique advantages to working with the CHR population as it aims to improve self-direction and recovery through stimulation of metacognitive capacity, a phenomenon that has been associated with recovery. This paper explores unique aspects of the CHR population and how MERIT can address barriers to recovery for individuals experiencing psychosis-like symptoms. Several case examples and a clinical vignette using MERIT to support patients with CHR are offered to exemplify this approach. MERIT offers a way to assist persons with CHR to address barriers to their personal recovery and to develop nuanced understandings of ways to master challenges.

A Review of Potential Neuroimaging Biomarkers of Schizophrenia-Risk

The risk for developing schizophrenia is increased among first-degree relatives of those with psychotic disorders, but the risk is even higher in those meeting established criteria for clinical high risk (CHR), a clinical construct most often comprising of attenuated psychotic experiences. Conversion to psychosis among CHR youth has been reported to be about 15-35% over three years. Accurately identifying individuals whose psychotic symptoms will worsen would facilitate earlier intervention, but this has been difficult to do using behavior measures alone. Brain-based risk markers have the potential to improve the accuracy of predicting outcomes in CHR youth. This narrative review provides an overview of neuroimaging studies used to investigate psychosis risk, including studies involving structural, functional, and diffusion imaging, functional connectivity, positron emission tomography, arterial spin labeling, magnetic resonance spectroscopy, and multi-modality approaches. We present findings separately in those observed in the CHR state and those associated with psychosis progression or resilience. Finally, we discuss future research directions that could improve clinical care for those at high risk for developing psychotic disorders.

Review of factors resulting in systemic biases in the screening, assessment, and treatment of individuals at clinical high-risk for psychosis in the United States

Background

Since its inception, research in the clinical high-risk (CHR) phase of psychosis has included identifying and exploring the impact of relevant socio-demographic factors. Employing a narrative review approach and highlighting work from the United States, sociocultural and contextual factors potentially affecting the screening, assessment, and service utilization of youth at CHR were reviewed from the current literature.

Results

Existing literature suggests that contextual factors impact the predictive performance of widely used psychosis-risk screening tools and may introduce systemic bias and challenges to differential diagnosis in clinical assessment. Factors reviewed include racialized identity, discrimination, neighborhood context, trauma, immigration status, gender identity, sexual orientation, and age. Furthermore, racialized identity and traumatic experiences appear related to symptom severity and service utilization among this population.

Conclusions

Collectively, a growing body of research from the United States and beyond suggests that considering context in psychosis-risk assessment can provide a more accurate appraisal of the nature of risk for psychosis, render more accurate results improving the field's prediction of conversion to psychosis, and enhance our understanding of psychosis-risk trajectories. More work is needed in the U.S. and across the globe to uncover how structural racism and systemic biases impact screening, assessment, treatment, and clinical and functional outcomes for those at CHR.

Three prominent self-report risk measures show unique and overlapping utility in characterizing those at clinical high-risk for psychosis

Self-report questionnaires have been developed to efficiently assess psychosis risk and vulnerability. Despite this, the validity of these questionnaires for assessing specific positive symptoms in those at clinical high risk for psychosis (CHR) is unclear. Positive symptoms have largely been treated as a uniform construct in this critical population and there have been no reports on the construct validity of questionnaires for assessing specific symptoms. The present study examined the convergent, discriminant, and criterion validity of the Launay Slade Hallucination Scale-Revised (LSHS-R), Prodromal Questionnaire-Brief (PQB), and Community Assessment of Psychic Experiences positive scale (CAPE-P) using a multimethod approach. CHR individuals (N = 71) and healthy controls (HC; N = 71) completed structured clinical interviews, self-report questionnaires, and neuropsychological tests. Questionnaire intercorrelations indicated strong convergent validity (i.e., all rs > .50); however, evidence for discriminant validity was more variable. In examining relations to interviewer-assessed psychosis symptoms, all questionnaires demonstrated evidence of criterion validity, though the PQB showed the strongest convergent correlations (e.g., r = .48 with total symptoms). In terms of discriminant validity for specific positive symptoms, results were again more variable. PQB subscales demonstrated limited specificity with positive symptoms, whereas CAPE-P subscales showed some specificity and the LSHS-R showed high specificity. In addition, when correlations with internalizing and externalizing symptoms were examined, only the PQB showed consistent significant correlations. These results are interpreted in terms of the strengths and limitations of each measure, their value for screening, and their potential utility for clarifying differences between specific positive symptoms.

Treatment outcomes for young people at clinical high risk for psychosis: Data from a specialized clinic

AIM

Treatment for youth exhibiting signs of clinical high risk for psychosis (CHR-P) has been emphasized in recent years, but there is need for a greater understanding of the course of symptoms and functioning across treatment. The aim of this study is to describe 10 years of naturalistic treatment outcomes in a real-world, specialized CHR-P outpatient clinic, the Center for Early Detection, Assessment, and Response to Risk (CEDAR) Clinic.

METHODS

The CEDAR Clinic routinely collects client outcomes data for the purposes of program development, monitoring treatment effectiveness, and characterizing the clinic population. Clients are assessed at baseline, every 6 months (for up to 2 years depending on duration of treatment), and at the end of treatment. A series of mixed-effects models were performed to analyse change over time in outcomes (symptoms and functioning) between baseline and follow-up time points.

RESULTS

Over time, clients' (N = 123) positive (F = 11.8, p < .001) and negative (F = 4.91, p = .002) symptoms declined relative to their baseline. Social functioning improved over time (F = 2.50, p = .049), as did depression (F = 8.60, p < .001) and hopelessness (F = 4.21, p = .004). Clients' total CEDAR treatment hours ranged across type of treatment service, but the amount of treatment clients received was not associated with any clinical outcomes.

CONCLUSIONS

Over the course of treatment at this real-world, specialized CHR-P program, clients exhibited significant improvement in clinical outcomes and did not significantly decline in any measured outcomes. We discuss this study in the context of current understanding and guidelines for specialized coordinated specialty care treatment for CHR-P.

Social work training to reduce duration of untreated psychosis: Methodology and considerations of a web-based training for community providers

AIM

Outcomes for individuals with psychotic disorders can be improved through early intervention services; however, identification continues to be a major problem in connecting individuals with these services. Social workers form a vast majority of the human service and mental health workforce in the United States and therefore have the potential to play a unique role in identifying and referring those who may benefit from specialty early intervention services.

METHODS

The current article describes the methodological design, implementation, and participant recruitment procedures of a large-scale, web-based training program for social workers promoting identification and referral of individuals with emerging symptoms of a mental illness with psychosis in the context of a randomized clinical trial.

RESULTS

The web-based study enrolled 1384 individuals. More than half of study participants enrolled within the first 3 months of the 14-month recruitment period. Completion of all study components was achieved by 959 individuals (69% of total enrolled), and completion status did not vary significantly by gender, ethnicity, or facility at which the individual was employed. Completion rates varied by race, such that participants identifying as White were more likely to complete the study, while those identifying as Black were less likely.

DISCUSSION

The results suggest the feasibility of using a web-based training program to engage social workers in early psychosis identification practices. Challenges related to encouraging participants to complete the training and lessons learned during the study recruitment are discussed.

Psychological Interventions for Young People With Psychotic Disorders: A Systematic Review

BACKGROUND

Psychotic disorders are commonly accompanied by intense psychological burden, and psychological interventions are usually needed in order to reduce the symptoms and help in maintaining or improving the level of psychological and social functioning after the onset of psychosis. The evidence-base for treating young people at risk for psychosis and adults with psychotic disorders is accumulating. Yet, pervasive systematic literature reviews that would include patients from the full age range being the most essential period for the risk of developing a psychotic disorder, a wide range of psychological interventions, and various types of clinical trials, have been lacking. The aim of this systematic review is to fill the gap by presenting the current research evidence from clinical trials on the effectiveness of psychological interventions for treating young people (12-30) with psychotic disorders.

METHODS

A systematic search was conducted in PubMed and PsycINFO followed by a 3-step screening process based on the PICOS strategy. Risk of bias of the included studies was assessed by the Mixed Methods Appraisal Tool (MMAT). Extracted data from the included studies is reported using a narrative synthesis.

RESULTS

Of the 1,449 publications screened, 40 from 25 studies were included in the review. Of these, 10 studies reported results from cognitive or behavioral therapy, nine from cognitive remediation therapy (CRT), and six from other types of therapies (i.e., integrative interventions combining psychoeducation and family/group interventions). All but one study found the target interventions to be effective, but the results mostly did not differ significantly from the control conditions in reducing symptoms and improving functioning, preventing relapses and hospitalization, or improving psychological or family variables. The most consistent findings were from CRT, showing more improvement in cognitive functioning compared to control conditions while not being superior in reducing symptom severity. Integrative interventions might be effective in treating young people suffering from psychotic disorders.

CONCLUSION

There is some evidence that psychological interventions are effective for young people with psychotic disorders. However, with regard to symptom severity, psychotherapy does not outperform control conditions, and the results do not strongly favor any specific type of treatment.

Preliminary evidence supporting the practice of psychosis-risk screening within an inpatient psychiatric setting serving adolescents

Evidence supports the use of brief psychosis-spectrum screening measures to identify individuals at elevated risk for psychosis, however, there is limited research on psychosis-spectrum screening among adolescents hospitalized for acute mental health concerns. Given the psychiatric vulnerability of this population, screening efforts within inpatient settings may help identify adolescents at greatest risk for ongoing mental health concerns including psychosis. This study investigates the use of two brief screening tools to identify psychosis-spectrum symptoms in psychiatrically hospitalized adolescents. Upon intake, adolescents completed two screening measures, the PRIME Screen-Revised and the Youth Self-Report Thought Problems scale, followed by a brief interview to evaluate psychosis-spectrum diagnoses. Associations between screening scores and diagnostic status were explored to evaluate the use of these tools to identify psychosis-spectrum conditions in this population. The sample included 57 adolescents, 28 of whom met psychosis-spectrum criteria. Psychosis-spectrum status was strongly correlated with PRIME scores (r = 0.59) and Thought Problems T scores (r = 0.55). Logistic regression analyses indicated that both screening measures demonstrate promising accuracy (74-81%) for identifying adolescents meeting psychosis-spectrum criteria. The PRIME and Thought Problems scale may be appropriate screening tools for use in adolescent inpatient settings to identify those experiencing clinically significant psychosis-spectrum symptoms.

Psychosis-spectrum experiences linked to specific psychotherapy readiness domains among psychiatrically hospitalized adolescents

AIM

Early psychosocial treatment for psychosis-spectrum symptoms has been linked to positive outcomes, whereas delayed treatment is associated with poorer prognosis. Thus, there is a critical need to bolster psychotherapy engagement efforts, particularly among high-risk groups and during high-risk periods, in order to maximize recovery. This study explores the relation between psychosis-spectrum symptoms and psychotherapy readiness among psychiatrically hospitalized adolescents, a foundational step for developing more effective psychotherapy engagement approaches for this population.

METHODS

Adolescents (n = 704; 12-18 years) who were admitted to a psychiatric inpatient unit completed the Readiness for Psychotherapy Index (RPI), a psychosis-spectrum questionnaire (PRIME Screen), and a brief diagnostic interview at intake. Correlational patterns and regression analyses were used to explore associations between variables.

RESULTS

The PRIME Screen was negatively associated with the RPI Openness subscale and positively associated with the Distress subscale, beyond the effects of demographics (ie, age, sex, race) and psychiatric diagnoses.

CONCLUSIONS

Results indicate that the RPI probes multiple facets of psychotherapy readiness that have unique associations with psychosis-spectrum experiences. Adolescents with higher PRIME scores endorsed greater mental health-related distress and lower levels of openness to psychotherapy. These psychotherapy readiness factors warrant further exploration, as they may be significant barriers or facilitators to engaging adolescents with psychosis-spectrum symptoms in much needed early treatment services.

Cognitive behavioural therapy for help-seeking adolescents and young adults with at-risk-mental state: Effects on subclinical positive symptoms

AIM

Cognitive behavioural therapy (CBT) is effective for at-risk-mental state (ARMS) in reducing/delaying transition to psychosis. However, previous systematic reviews pointed out the small number of trials as a limitation and suggested that additional outcomes should be evaluated, not only prevention of first psychosis episode. No study assessed the CBT effects on subclinical psychotic symptoms. The present study investigated the effects of CBT on the transition risk (primary outcome), and on overall remission from ARMS and severity of subclinical symptoms, that is, unusual content of thought, non-bizarre ideas, perceptual abnormalities, disorganized speech (secondary outcome).

METHODS

CBT consisted of 30 individual weekly sessions over 7 months. Fifty-eight participants with ARMS detected by the Comprehensive Assessment of At-Risk-Mental States were randomized to CBT or control condition.

RESULTS

Respectively in the CBT and control groups, 1 (3.40%) and 5 (26.31%) participants at post-treatment and 3 (10.30%) and 8 (42.10%) at follow-up made transition with a difference between the two groups, despite at borderline significance. At post-treatment and follow-up, respectively, the number of participants recovered from ARMS was significantly higher in CBT (76.92% and 61.53%) than in control (10.52% and 15.80%). Participants in the control group reported lower reductions on all the subclinical symptoms over time as compared with those in CBT.

CONCLUSIONS

This is the first study assessing CBT on subclinical positive symptoms in ARMS. CBT seems to be a tailored approach able to produce short- and long-term benefits on this outcome.

Cognitive Behavioral Therapy for Prodromal Stage of Psychosis-Outcomes for Transition, Functioning, Distress, and Quality of Life: A Systematic Review and Meta-analysis

OBJECTIVE

This study aimed to provide insight into the efficacy of cognitive-behavioral therapy for psychosis (CBTp) in patients with "clinical high risk of psychosis (CHR-P)".

METHODS

Major scientific databases were searched up to April 17, 2020. Randomized controlled trials in CHR-P individuals, comparing CBTp with needs-based interventions (NBI, including treatment as usual or nonspecific control treatment) were included, following PRISMA guidelines. The primary outcome (efficacy) was transition to psychosis by 6 months, 12 months, 24 months, and over 24 months. Secondary outcomes were change in attenuated psychotic symptoms, depression, distress, improvements in functioning, and quality of life.

RESULTS

Ten randomized controlled studies met inclusion criteria. The comparisons included 1128 participants. CBTp was significantly more efficacious in reducing rate of transition to psychosis by 6 months (after post-hoc sensitivity analysis) (relative risk [RR] = 0.44, 95% confidence interval [CI]: 0.26, 0.73), 12 months (RR = 0.44, 95% CI: 0.30, 0.64), 12 months (RR = 0.46, 95%CI: 0.30, 0.69), and over 24 months (RR = 0.58, 95% CI: 0.35, 0.95) after treatment, compared with those receiving NBI. CBTp was also associated with more reduced attenuated psychotic symptoms by 12 months (SMD = -0.17, 95% CI: -0.33, -0.02) and by 24 months (SMD = -0.24, 95% CI: -0.43, -0.06). No beneficial effects on functioning, depression, quality of life, or distress were observed favoring CBTp.

CONCLUSIONS

CBTp is effective in reducing both psychosis transition rates and attenuated psychotic symptoms for the prodromal stage of psychosis. It is a promising intervention at the preventative stage.

Psychological interventions for people with psychotic experiences: A systematic review and meta-analysis of controlled and uncontrolled effectiveness and economic studies

OBJECTIVE

Many people with psychotic experiences do not develop psychotic disorders, yet those who seek help demonstrate high clinical complexity and poor outcomes. In this systematic review and meta-analysis, we evaluated the effectiveness and cost-effectiveness of psychological interventions for people with psychotic experiences.

METHOD

We searched 13 databases for studies of psychological interventions for adults with psychotic experiences, but not psychotic disorders. Our outcomes were the proportion of participants remitting from psychotic experiences (primary); changes in positive and negative psychotic symptoms, depression, anxiety, functioning, distress, and quality of life; and economic outcomes (secondary). We analysed results using multilevel random-effects meta-analysis and narrative synthesis.

RESULTS

A total of 27 reports met inclusion criteria. In general, there was no strong evidence for the superiority of any one intervention. Five studies reported on our primary outcome, though only two reports provided randomised controlled trial evidence that psychological intervention (specifically, cognitive behavioural therapy) promoted remission from psychotic experiences. For secondary outcomes, we could only meta-analyse trials of cognitive behavioural therapy. We found that cognitive behavioural therapy was more effective than treatment as usual for reducing distress (pooled standardised mean difference: -0.24; 95% confidence interval = [-0.37, -0.10]), but no more effective than the control treatment for improving any other outcome. Individual reports indicated that cognitive behavioural therapy, mindfulness-based cognitive therapy, sleep cognitive behavioural therapy, systemic therapy, cognitive remediation therapy, and supportive treatments improved at least one clinical or functional outcome. Four reports included economic evaluations, which suggested cognitive behavioural therapy may be cost-effective compared with treatment as usual.

CONCLUSION

Our meta-analytic findings were primarily null, with the exception that cognitive behavioural therapy may reduce the distress associated with psychotic experiences. Our analyses were limited by scarcity of studies, small samples and variable study quality. Several intervention frameworks showed preliminary evidence of positive outcomes; however, the paucity of consistent evidence for clinical and functional improvement highlights a need for further research into psychological treatments for psychotic experiences.

Telepsychotherapy with Youth at Clinical High Risk for Psychosis: Clinical Issues and Best Practices during the COVID-19 Pandemic

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.

EPA guidance on the early intervention in clinical high risk states of psychoses

This guidance paper from the European Psychiatric Association (EPA) aims to provide evidence-based recommendations on early intervention in clinical high risk (CHR) states of psychosis, assessed according to the EPA guidance on early detection. The recommendations were derived from a meta-analysis of current empirical evidence on the efficacy of psychological and pharmacological interventions in CHR samples. Eligible studies had to investigate conversion rate and/or functioning as a treatment outcome in CHR patients defined by the ultra-high risk and/or basic symptom criteria. Besides analyses on treatment effects on conversion rate and functional outcome, age and type of intervention were examined as potential moderators. Based on data from 15 studies (n = 1394), early intervention generally produced significantly reduced conversion rates at 6- to 48-month follow-up compared to control conditions. However, early intervention failed to achieve significantly greater functional improvements because both early intervention and control conditions produced similar positive effects. With regard to the type of intervention, both psychological and pharmacological interventions produced significant effects on conversion rates, but not on functional outcome relative to the control conditions. Early intervention in youth samples was generally less effective than in predominantly adult samples. Seven evidence-based recommendations for early intervention in CHR samples could have been formulated, although more studies are needed to investigate the specificity of treatment effects and potential age effects in order to tailor interventions to the individual treatment needs and risk status.

Negative symptoms in the clinical high-risk state for psychosis: Connection with cognition and primacy in impacting functioning

AIM

In the clinical high-risk (CHR) state for psychosis, both negative symptoms and lower cognitive function have been associated with poorer daily functioning. Recent evidence suggests that negative symptoms share overlapping variability with cognition and may partially mediate the relationship between cognition and functioning. However, the nature of this overlap is unknown, and the reverse mediation model remains untested leaving the precise nature of these associations unclear.

METHODS

In order to clarify these relationships, a sample of community-dwelling youth meeting CHR criteria was collected from a specialty CHR clinic (n = 91, mean age = 21, 63% male). Bootstrapping methods were then applied in a mediation analysis to test both negative symptoms and cognition as independent variables and mediating variables predicting social and role functioning in CHR individuals. Canonical correlation analysis was used to characterize the overlapping variability between negative symptoms and cognition.

RESULTS

Support for a primary role of negative symptoms in predicting functioning and cognition was observed. Canonical correlation revealed a single dimension of overlap between the two symptom types (r = .62), represented by a strong correlation between negative symptoms in general and tasks involving verbal working memory, vigilance and social cognition specifically. A single cognitive factor composed primarily of these tasks was found to predict role functioning (adjusted R ² = .04).

CONCLUSIONS

The results highlight the importance of considering specific cognitive mechanisms overlapping with negative symptoms in research and rehabilitative practice in CHR populations, as well as the primary importance of targeting negative symptoms.

Evaluation of the Combined Treatment Approach "Robin" (Standardized Manual and Smartphone App) for Adolescents at Clinical High Risk for Psychosis

Introduction: The prevention of schizophrenia and other psychotic disorders has led researchers to focus on early identification of individuals at clinical high risk (CHR) for psychosis and to treat the at-risk symptoms in the pre-psychotic period. Although at-risk symptoms such as attenuated hallucinations or delusions are common in adolescents and associated with a marked reduction in global functioning, the evidence base of effective interventions for adolescents at CHR state and even first-episode psychosis is limited. Thus, the present protocol describes a study design that combines therapy modules for CHR adolescents with a smartphone application supporting the young individuals between the therapy sessions. The treatment approach "Robin" is based on existing therapy strategies for adolescents with first episode of psychosis and the available recommendations for adults with at-risk symptoms. Methods: The evaluation aims firstly to compare the efficacy of Robin in 30 CHR adolescents aged 14-18 to an active control group (treatment as usual) from a previous study. Primary outcome measures will be at-risk symptomatology, comorbid diagnosis, functioning, self-efficacy, and quality of life. For the prospective intervention condition (16 weekly individual sessions + a minimum 4 family sessions), help-seeking adolescents with CHR for psychosis, aged 14-18, will be recruited over 3 years. At-risk and comorbid symptoms, functioning, self-efficacy, and quality of life are monitored at six time points (baseline, during the treatment period; immediately after intervention; and 6, 12, and 24 months later) and compared with the respective measures of the active control group. Discussion: To the best of our knowledge, this is the first controlled trial to test the efficacy of a specific early psychosis treatment in combination with a smartphone application for adolescents at CHR for developing psychosis. The results of the study are expected to add information that may substantially decrease the burden of CHR adolescents and increase their resilience. It may offer age-adapted and targeted strategies to guide clinicians in the treatment of these vulnerable individuals. Furthermore, research in the field of early intervention will be enriched by our findings. Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT03829527.

Individual Differences and Psychosis-Risk Screening: Practical Suggestions to Improve the Scope and Quality of Early Identification

Approaches to identifying individuals at clinical high-risk (CHR) for psychosis currently do not carefully weigh considerations around individual differences. Effective identification depends on awareness of factors beyond psychopathology as it is reflected in the current literature, such as sensitivity to idiographic circumstances and individual differences. The inability to address contextual factors when employing the status quo method of identification likely contributes to the unacceptably poor accuracy when identifying people at CHR. Individual differences related to factors such as culture, race, comorbidity, and development likely play an important role in accurate identification, and have the potential to improve the validity of approaches intended to identify this population. Tailored approaches to assessment based on an awareness of context, identity, setting, and preferences of clients are possible, and customizing assessment efforts accordingly may be useful for accurate identification of people at CHR. Highlighting the potential for the existing early identification paradigm to marginalize or misunderstand certain groups, we describe how effective identification and ethical diagnosis require sensitivity to individual differences writ large. We suggest that recognizing the importance of these factors advances a more inclusive and accurate approach to identification.

Family functioning moderates the impact of psychosis-risk symptoms on social and role functioning

BACKGROUND

Youth at clinical high-risk (CHR) for psychosis often experience difficulties in social and role functioning. Given evidence that family stress and support can impact psychosis-risk symptoms, as well as an individual's ability to fulfill social and role functions, family dynamics are hypothesized to moderate the effect of psychosis-risk symptoms on functioning.

METHODS

Participants at CHR (N = 52) completed the clinician-administered Structured Interview for Psychosis-risk Syndromes (SIPS) and the Family Assessment Device (FAD) General Functioning Scale, a self-report measure of family functioning including cohesion and support. Interviewers rated participants' current social and role functioning using the Global Functioning: Social and Role Scales.

RESULTS

Regression results indicated that positive symptoms, but not ratings of family functioning, statistically predicted social and role functioning. Perceived family functioning, however, moderated the effect of symptoms on social/role functioning. For individuals who perceived lower levels of family functioning, symptoms were moderately associated with social and role functioning (f² = 0.17 and f² = 0.23, respectively). In contrast, psychosis-risk symptoms were not significantly associated with social/role functioning for individuals with higher levels of perceived family functioning. Notably, positive symptoms and perceived family functioning were not associated with one another, suggesting that perceived family functioning did not directly impact symptom severity, or vice versa.

CONCLUSIONS

Findings support the notion that family functioning may be a clinically meaningful factor for individuals at CHR. Although this cross-sectional data limits our discussion of potential mechanisms underlying the pattern of findings, results suggest that familial support may be beneficial for individuals at risk for psychosis.

Cognitive behavioural therapy for worry in young individuals with at-risk mental states: a preliminary investigation

Cognitive behavioural therapy (CBT) is a first-line strategy in reducing or delaying risk of transition to psychosis among young individuals with at-risk mental states (ARMS). However, there is little knowledge about its effects on other outcomes associated with ARMS. No study on CBT for ARMS has assessed worry, an important process associated with this condition. The present study investigated changes in worry at immediate post-treatment and 14-month follow-up after CBT for young individuals with ARMS seeking psychiatric care in mental health services. Thirty-seven young individuals (mean age = 26 years, SD = 6.07; 22.20% female) seeking psychiatric care in mental health services and classified as reporting ARMS through the Comprehensive Assessment of At-Risk Mental States were included. The Positive And Negative Syndrome Scales (PANSS) and Penn State Worry Questionnaire (PSWQ) were administered at baseline, post-treatment, and follow-up. CBT consisted of 30 weekly individual 1-hour sessions based on a validated CBT for ARMS manual enriched with components targeting worry [psychoeducation, problem-solving, (meta)cognitive restructuring, behavioural experiments]. Seven participants (18.91%) at follow-up had cumulatively made transition to psychosis. Repeated measures ANOVA with post-hoc pairwise comparisons showed significant changes in PSWQ scores from baseline to post-treatment and from baseline to follow-up; PSWQ scores remained stable from post-treatment to follow-up. This is the first study investigating changes in worry after CBT for ARMS, which appears to be a promising strategy also for this outcome. Future research with a larger sample size and control group may determine whether changes in worry are also associated with reduced transition risk.

Psychotherapy in Psychosis: Experiences of Fully Recovered Service Users

Background: Despite the evidence of the importance of including service users' views on psychotherapy after psychosis, there is a paucity of research investigating impact on full recovery. Objectives: To explore what fully recovered service users found to be the working ingredients of psychotherapy in the recovery process after psychosis. Materials and Methods: The study was designed as a phenomenological investigation with thematic analysis as the practical tool for analysis. Twenty fully recovered service users were interviewed. Results: Themes: (1) Help with the basics, (2) Having a companion when moving through chaotic turf, (3) Creating a common language, (4) Putting psychosis in brackets and cultivate all that is healthy, and (5) Building a bridge from the psychotic state to the outside world. Conclusion: Therapeutic approaches sensitive to stage specific functional challenges seemed crucial for counteracting social isolation and achieving full recovery. Findings indicate that psychotherapy focusing on early readjustment to everyday activities, to what are perceived as meaningful and recovery-oriented, seems to be what is preferred and called for by service users.

Recent advances in the prevention of mental disorders

PURPOSE

Prevention of mental disorders is a rapidly growing area of research with substantial potential benefits for population health. This paper reviews the evidence base for prevention of depression, anxiety, and schizophrenia.

METHODS

We synthesized evidence from recent systematic reviews and meta-analyses published between 2013 and 2018 on prevention of depression, anxiety, and first-episode psychosis. We included reviews of randomized controlled trials testing psychological, psychosocial, and pharmacological preventive interventions.

RESULTS

There is good evidence that depression and anxiety can be prevented, although effect sizes are generally small. Indicated prevention of first-episode psychosis appears promising. Economic evaluations provide support for prevention of depression, anxiety, and first-episode psychosis, but more studies evaluating costs and benefits are needed to strengthen the knowledge base, particularly regarding long-term outcomes, which include chronicity of the prevented disorder, as well as later occurence of important comorbid mental and physical health problems. Promising areas for further development include internet- or computer-based prevention strategies, mindfulness-based interventions, and integration of prevention programs within occupational settings.

CONCLUSIONS

A number of interventions to prevent mental disorders are efficacious. While intervention effect sizes are generally small for prevention of depression and anxiety, they may nonetheless be of significant population benefit. Using the growing evidence base to inform policy and dissemination of evidence-based prevention programs is critical for moving prevention science into real-world settings.

Potentially important periods of change in the development of social and role functioning in youth at clinical high risk for psychosis

The developmental course of daily functioning prior to first psychosis-onset remains poorly understood. This study explored age-related periods of change in social and role functioning. The longitudinal study included youth (aged 12-23, mean follow-up years = 1.19) at clinical high risk (CHR) for psychosis (converters [CHR-C], n = 83; nonconverters [CHR-NC], n = 275) and a healthy control group (n = 164). Mixed-model analyses were performed to determine age-related differences in social and role functioning. We limited our analyses to functioning before psychosis conversion; thus, data of CHR-C participants gathered after psychosis onset were excluded. In controls, social and role functioning improved over time. From at least age 12, functioning in CHR was poorer than in controls, and this lag persisted over time. Between ages 15 and 18, social functioning in CHR-C stagnated and diverged from that of CHR-NC, who continued to improve (p = .001). Subsequently, CHR-C lagged behind in improvement between ages 21 and 23, further distinguishing them from CHR-NC (p < .001). A similar period of stagnation was apparent for role functioning, but to a lesser extent (p = .007). The results remained consistent when we accounted for the time to conversion. Our findings suggest that CHR-C start lagging behind CHR-NC in social and role functioning in adolescence, followed by a period of further stagnation in adulthood.

Associations of attention-deficit/hyperactivity and other childhood disorders with psychotic experiences and disorders in adolescence

Prodromal symptoms of psychosis are associated with an increased risk of transition, functional impairment, poor mental health, and unfavorable developmental prospects. Existing interventions targeting the prodrome are non-satisfactory. It may thus be more promising to attempt to identify risk factors in the premorbid phase preceding the prodrome to increase the chances of successful preventive approaches. Here, we investigate whether childhood mental disorders in general and attention-deficit/hyperactivity disorder (ADHD) specifically indicate a risk for subsequent psychotic experiences and disorders. We used a sample from the prospective Avon Longitudinal Study of Parents and Children (N = 5528). When the participants were 7 years old, mental disorders were assigned according to the DSM-IV. In standardized interviews, psychotic experiences were assessed at age 12 and psychotic disorders at age 18. We examined the associations of each of the childhood mental disorders alone and in combination with psychotic experiences at age 12 and psychotic disorders at age 18 using logistic regression. Compared to participants without a disorder, participants with a mental disorder had a higher risk of psychotic experiences at age 12 (OR 1.70, 95 % CI 1.28-2.27) and of psychotic disorders at age 18 (OR 2.31, 95 % CI 1.03-5.15). Particularly, the ADHD combined subtype at age 7 was strongly associated with psychotic experiences at age 12 (OR 3.26, 95 % CI 1.74-6.10). As expected, childhood mental disorders are risk indicators of psychotic experiences and disorders. To improve prevention, health care professionals need to screen for psychotic experiences in children with non-psychotic disorders.

Stigma and need for care in individuals who hear voices

BACKGROUND

Voice hearing experiences, or auditory verbal hallucinations, occur in healthy individuals as well as in individuals who need clinical care, but news media depict voice hearing primarily as a symptom of mental illness, particularly schizophrenia.

AIMS

This article explores whether, and how, public perception of an exaggerated association between voice hearing and mental illness might influence individuals' need for clinical care.

METHOD

A narrative literature review was conducted, using relevant peer-reviewed research published in the English language.

RESULTS

Stigma may prevent disclosure of voice hearing experiences. Non-disclosure can prevent access to sources of normalizing information and lead to isolation, loss of social support and distress. Internalization of stigma and concomitantly decreased self-esteem could potentially affect features of voices such as perceived voice power, controllability, negativity and frequency, as well as distress. Increased distress may result in a decrease in functioning and increased need for clinical care.

CONCLUSION

The literature reviewed suggests that stigma has the potential to increase need for care through many interrelated pathways. However, the ability to draw definitive conclusions was constrained by the designs of the studies reviewed. Further research is needed to confirm the findings of this review.

Early Intervention in Schizophrenia: A Literature Review

Schizophrenia is a debilitating psychiatric disorder seen across the world. Recently, investigators have witnessed an upsurge in research on the potential benefits of early intervention during the prodromal stage: the sooner people start the treatment at their first psychotic episode, the better outcome on symptom relief and better functioning. This paper aims to critically review and synthesize empirical evidence published between 2005 and 2015 regarding the effectiveness of preemptive interventions on transition rate, symptom severity, depression, anxiety, and function level. Randomized controlled trials were identified in seven different electronic databases and twelve studies were included in this review. Findings indicated that intervention was designed not only for help-seeking individuals, but also for their family members. Also, the applications for psychiatric nursing are discussed.

The Common Elements of treatment engagement for clinically high-risk youth and youth with first-episode psychosis

AIM

Without treatment, clinically high-risk (CHR) youth or youth with first-episode psychosis (FEP) have increased risk for significant complications from their illness; yet, treatment engagement among these youth is critically low. The purpose of this study was to examine engagement efforts with CHR/FEP youth to stimulate new ideas that might facilitate participation in services for this population.

METHODS

A literature review using distillation methods identified engagement practices reported in two bodies of literature. The first body of literature (i.e. 'CHR/FEP engagement') included 13 studies employing qualitative designs to explore consumer perspectives about treatment engagement practices in samples of CHR/FEP youth and their families. The second body of research (i.e. 'CHR/FEP RCTs') included 18 randomized controlled trials (RCTs) testing treatments for CHR/FEP youth and their families. Engagement practice frequencies were compared with the frequency of these practices within effective engagement interventions, as tested in 40 RCTs within the broader child and adolescent mental health literature (i.e. 'CAMH engagement').

RESULTS

Treatment attrition and attendance were the most frequent engagement outcomes measured in the CHR/FEP RCTs. There were notable efforts described in the CHR/FEP RCTs towards engaging youth and families, yet CHR/FEP RCTs reportedly included only a small proportion of engagement practices described in either the CHR/FEP or CAMH engagement literatures.

CONCLUSION

Results suggest there might be practices available to complement current efforts at engaging CHR/FEP youth in treatment, and that increased attention to the measurement of engagement outcomes could provide important information regarding engagement in a population with low treatment engagement rates.

Attenuated psychosis syndrome: benefits of explicit recognition

Given the unique characteristics of people who meet criteria for attenuated psychosis syndrome (APS) and the growing literature on the clinical benefits of providing services to individuals who meet these criteria, the APS diagnosis serves an important, and previously missing, role in psychiatry. The promotion of the APS diagnosis should help reduce the over-diagnosis and over-treatment of individuals with prodromal psychotic conditions and it should also encourage expanded training about attenuated psychosis among clinicians who primarily provide services to youth (a primary group who are diagnosed with APS). Only some of the individuals with APS subsequently develop psychosis, but all have existing clinical needs – regardless of subsequent conversion. The formal recognition of APS in DSM-5 will facilitate the research needed to identify and meet those needs.

Emotional and behavioral symptomatology reported by help-seeking youth at clinical high-risk for psychosis

Subthreshold psychosis-like experiences are typically the focus of psychosis-risk screening as they are associated with a greater propensity for future illness. Potentially prodromal individuals identified as being at clinical high-risk (CHR), however, report a variety of distressing and impairing mental health symptoms in addition to subthreshold psychosis symptoms, indicating that this population is of clinical interest regardless of whether or not they develop psychosis. In the current study, 90 young people (12-21) seeking mental health services completed the Behavior Assessment System for Children, Second Edition (BASC-2), a broad-range checklist of emotional and behavioral concerns and adaptive skills, followed by the Structured Interview for Psychosis-risk Syndromes to assess psychosis risk. Those who met criteria for CHR (n=35) reported elevated scores across several BASC-2 scales including depression, attention problems, locus of control, and sense of inadequacy compared to help-seeking youth without CHR (n=55). Most of these scales were also elevated compared to general population norms. Further, the CHR group had significantly lower scores on two adaptive scales, self-reliance and relations with parents, indicating more impairment in these domains. Results indicate that young people at CHR experience more pervasive and/or more severe symptomatology across several domains of clinical significance compared to a similar group of help-seeking youth not at CHR. Results from this study aid in the understanding of symptom correlates of CHR status beyond attenuated symptoms that can provide clinical information relevant for treatment.

Early Detection of Psychosis: Recent Updates from Clinical High-Risk Research

The debilitating nature of schizophrenia necessitates early detection of individuals at clinical high-risk (CHR) in order to facilitate early intervention. In particular, comparisons between those who develop fully psychotic features (CHR+) and those who do not (CHR-) offer the opportunity to reveal distinct risk factors for psychosis, as well as possible intervention target points. Recent studies have investigated baseline clinical, neurocognitive, neuroanatomic, neurohormonal, and psychophysiological predictors of outcome; premorbid social dysfunction, deficits in neurocognitive performance, neuroanatomic changes, and hypothalamic-pituitary-adrenal (HPA) axis dysfunction have been implicated in psychosis emergence. However, several challenges within CHR research remain: heterogeneity in long-term diagnostic outcome, the variability of research tools and definitions utilized, and limited longitudinal follow-up. Future work in the field should focus on replication via extended longitudinal designs, aim to explore the trajectories and inter-relationships of hypothesized biomarkers, and continue to investigate interventions that seek to prevent psychosis emergence through symptom reduction.

Psychosis risk screening: a systematic review

Despite the wealth of evidence linking duration of untreated psychosis to critical illness outcomes, most clinicians do not utilize any formal evaluation tools to identify attenuated or emerging psychotic symptoms. Given the costs associated with training and administration, interview-based assessments such as the Structured Interview for Psychosis Risk Syndromes (SIPS) are not likely to be widely adopted for clinical use. The ability to identify high-risk individuals through low-cost, brief methods is essential to the success of scalable prevention efforts. The aim of this article is to present a comprehensive review of the use of self-report forms as psychosis risk "screeners." A literature search revealed 34 investigations in which authors used a self-report questionnaire as a first-step screener in a clinical high-risk assessment protocol. Information about each screener, including reported psychometric data, is presented within the review. Psychosis risk screeners have been used in diverse samples with the goals of validating assessments, screening populations for clinical referral, recruiting samples of interest for research participation, and estimating symptom prevalence and severity. Screeners focusing on attenuated psychotic experiences appear to measure a reliable construct with variable prevalence in help-seeking and general population samples. Administration of screeners to help-seeking populations can identify enriched samples with substantially elevated likelihood of meeting CHR criteria and transitioning to psychosis over time. More research is needed, however, to establish reliable norms and screening thresholds, as score elevations indicating a likely high-risk respondent appear to be unreliable across populations and settings.

Using parent and youth reports from the Behavior Assessment System for Children, Second Edition to identify individuals at clinical high-risk for psychosis

Brief self-report screening can help facilitate early identification of individuals at risk for or in early stages of psychosis. Existing screening tools focus on self-reported attenuated positive symptoms to detect potential risk; however, parent reports may also be helpful for assessing symptoms, especially in younger patients. Recent evidence has shown that the "atypicality" scale within the self-report form of the Behavior Assessment System for Children, Second Edition (BASC-2) may be useful for identifying high-risk youth within a more clinically comprehensive and potentially minimally stigmatizing format. The BASC-2 parent report form also includes the atypicality scale, but no research has investigated the relation of this scale to psychosis risk. The aim of the current study is to evaluate the association of parent along with youth reports of BASC-2 atypicality with attenuated positive symptoms as assessed by the Structured Interview for Psychosis-Risk Syndromes (SIPS), in a sample of help-seeking adolescents (n=63). Results indicate that both parent and youth reports of atypicality predict clinician-rated symptoms. Moreover, the combination of parent and youth report significantly improved prediction of SIPS scores over either single-informant scale. These findings suggest that parent report scales, as ascertained through part of a larger, commonly used measure, may help identify youth at risk for psychosis, particularly if used in conjunction with youth self-report.
