Creation of a Psychotic Disorders Research Advisory Board as a Shared Resource

Community engagement is important for research, yet many researchers do not routinely seek feedback from people with lived experience. A key barrier to this engagement is that the resources required to create an advisory board may be unavailable to individual investigators, and creating an advisory board for a single study may often be impractical. In this column, the authors describe how to create a standing research advisory board that can serve as a shared resource for researchers and community members and provide a psychosis research advisory board example to aid discussion.

Readiness for treatment predicts depression outcomes in a partial hospital program

Evidence-based interventions vary in effectiveness for individuals with depression, which has a large public health burden. Readiness for change or treatment can be an important individual difference predictor of depression outcomes. To inform public service initiatives targeting readiness for treatment, characterizing readiness across settings and levels of care is key. However, limited data exist on the role of readiness for treatment in acute psychiatric settings and in particular, partial hospital programs which are key points in the continuity of inpatient and outpatient care. The present study assessed readiness for treatment in terms of importance, confidence, and motivation to engage in a partial hospital program and tested whether higher levels of readiness were associated with better treatment outcomes among clients with depression. Participants (N = 192) with major depressive disorder rated their readiness for treatment (Readiness Rulers), depression (Patient Health Questionnaire-9), and global improvement (Clinical Global Impression Scale-Improvement Self-Report) while enrolled in a partial hospital program. Generalized linear regression models assessed the effect of baseline readiness on outcomes at discharge, adjusted for baseline level of the outcome, age, sex, race, and ethnicity. Greater baseline readiness predicted reduced depression and better global improvement at discharge. Higher confidence and motivation to engage in treatment, but not importance, were associated with better depression outcomes. Identifying and addressing readiness for treatment by leveraging public health systems and services (e.g., help lines, family interventions) prior to or upon starting a partial hospital program may be useful to maximize gains in treatment.

Clues from caregiver emotional language usage highlight the link between putative social environment and the psychosis-risk syndrome

Familial emotional word usage has long been implicated in symptom progression in schizophrenia. However, few studies have examined caregiver emotional word usage prior to the onset of psychosis, among those with a clinical high-risk (CHR) syndrome. The current study examined emotional word usage in a sample of caregivers of CHR individuals (N = 37) and caregivers of healthy controls (N = 40) and links with clinical symptoms in CHR individuals. Caregivers completed a speech sample task in which they were asked to speak about the participant; speech samples were then transcribed and analyzed for general positive (e.g. good) and negative (e.g., worthless) emotional words as well as words expressing three specific negative emotions (i.e., anxiety, anger, and sadness) using Linguistic Inquiry and Word Count (LIWC). Findings indicated that (1) CHR caregivers used more negative and anxiety words compared to control caregivers; and (2) less positive word usage among CHR caregivers were related to more positive symptomatology among CHR individuals. These findings point toward the utility of automated language analysis in assessing the intersections between caregiver emotional language use and psychopathology.

Pilot development and feasibility of telehealth Community Reinforcement and Family Training (CRAFT) for early psychosis and substance use

Substance use is associated with poor outcomes for individuals with early psychosis. Community Reinforcement and Family Training (CRAFT) is an evidence-based approach that helps families to reduce substance use, engage in treatment, and improve family wellbeing, but it has not yet been studied for psychosis and substance use. The present study aimed to develop and evaluate a telehealth intervention utilizing CRAFT for families experiencing early psychosis and substance use. Twenty family members completed six to eight telehealth sessions of CRAFT adapted for early psychosis (CRAFT-EP). Participants completed an assessment battery at baseline, mid- and post-intervention, a three-month follow-up, surveys after each session, and a focus group to measure mean percentage of sessions completed, mean program satisfaction ratings, telehealth preference, and qualitative feedback. Participants had 100% session completion, and program satisfaction was at or near excellent for 99% of sessions. Half of participants preferred a primarily virtual hybrid program, whereas 45% preferred exclusively virtual visits. Communication was the most helpful topic, and participants requested additional written examples and resources. CRAFT-EP is feasible and acceptable to serve as the active intervention in a pilot randomized controlled trial comparing treatment as usual plus CRAFT-EP to treatment as usual.

Impact of the COVID-19 Pandemic on the Employment and Educational Outcomes of Individuals in a First-Episode Psychosis Clinic

OBJECTIVE

A central objective of early psychosis therapy is to restore social functioning (e.g., through employment and education). Employment and educational outcomes during the COVID-19 pandemic were examined in a well-defined cohort of patients receiving care in an early psychosis clinic.

METHODS

Data were extracted from the electronic health records of 128 patients receiving care at McLean Hospital's first-episode psychosis (FEP) clinic between January 1 and September 21 in 2019 and 2020. Using a generalized linear model with a Gaussian distribution and robust standard errors, the authors compared the average changes in the weekly employment and education proportions before and after COVID-19 lockdowns with the same changes in 2019.

RESULTS

Employment losses among patients with FEP were greater than among the general population and persisted through the end of follow-up. In 2020, average employment after a stay-at-home order was instituted was 33% lower than before the order compared with the change in employment during the same period in 2019. The effect was stronger among men and those who identified as non-White, were age <21 years, or did not have a college education. Although educational engagement recovered in the fall of 2020, it still remained below the 2019 levels.

CONCLUSIONS

Employment disruptions were major and persistent among the FEP population, which might affect short- and long-term outcomes. Innovative approaches are needed to help patients transition to remote employment, file unemployment claims, and use online hiring platforms to ameliorate the indirect effects of the COVID-19 pandemic.

Acute Physiological and Psychological Stress Response in Youth at Clinical High-Risk for Psychosis

Deficits in stress-response systems are a characteristic of schizophrenia and psychosis spectrum illnesses, and recent evidence suggests that this impairment may be evident in those at clinical high-risk (CHR) for the development of a psychotic disorder. However, there is limited research specifically investigating biological and subjective stress reactivity in CHR individuals. In the present study, 38 CHR individuals and group of 38 control individuals participated in the Trier Social Stress Test (TSST), an experimentally induced psychosocial stressor. Changes in salivary cortisol and alpha amylase, as well as self-reported units of distress (SUDS), were evaluated. Interestingly, the TSST did not induce a change in cortisol levels in either group, though the CHR group did show higher overall cortisol levels throughout the TSST (pre-anticipation period through recovery period). However, indicative of an effective task manipulation, the TSST did illicit an increase in alpha amylase in both groups. CHR participants exhibited higher levels of subjective stress prior to the stressor compared to the control group and CHR SUDs did not significantly increase in response to the stressor. In contrast, the control group showed an increase in SUDS in response to the stressor. Notably, SUDS for the control group post task mirrored the levels CHR youth endorsed prior to the stressor. Taken together, these findings suggest that there may be a functional relationship between persistently elevated cortisol and chronic high levels of subjective distress in CHR individuals.

Sex differences in morning cortisol in youth at ultra-high-risk for psychosis

Research suggests abnormalities in hypothalamic-pituitary-adrenal (HPA) axis function play an important role in the pathophysiology of psychosis. However, there is limited research on the biological stress system in young people at ultra high risk (UHR) for psychosis. Morning cortisol levels are particularly relevant to study in this context, as these markers reflect HPA regulation. This is the first examination of sex differences in morning cortisol levels in UHR individuals. Twenty-eight UHR and 22 matched healthy control participants were assessed in respect to symptoms and had home-based collection of salivary cortisol over three time points in the morning. It was predicted that the UHR participants would exhibit lower morning cortisol levels and lower cortisol would be associated with greater symptomatology (i.e. higher positive, negative, and depressive symptoms). Additionally, sex differences in morning cortisol levels were explored based on recent evidence suggesting that sex differences may play an important role in the exacerbation of psychosis. While there were no group differences in morning salivary cortisol secretion, there was a sex by time interaction among UHR individuals, such that only UHR males exhibited flat cortisol levels across two hours after awakening, whereas UHR females had a pattern of cortisol secretion similar to healthy controls, even among medication-free individuals (F=6.34, p=0.004). Cortisol AUC (area under the curve) across the three time points had a trend association (medium effect size; r=0.34, p=0.08) with depressive, but not positive or negative, symptom severity. These results stress the importance of considering sex differences in the psychosis-risk period, as they improve understanding of pathogenic processes.

Hippocampal Shape Abnormalities Predict Symptom Progression in Neuroleptic-Free Youth at Ultrahigh Risk for Psychosis

INTRODUCTION

Hippocampal abnormalities have been widely studied in schizophrenia spectrum populations including those at ultrahigh risk (UHR) for psychosis. There have been inconsistent findings concerning hippocampal morphology prior to and during the transition to psychosis, and little is known about how specific subregions are related to the symptom progression.

METHODS

A total of 80 participants (38 UHR and 42 healthy controls) underwent a 3T MRI scan, as well as structured clinical interviews. Shape analysis of hippocampi was conducted with FSL/FIRST vertex analysis to yield a localized measure of shape differences between groups. A subgroup of the sample (24 UHR and 24 controls) also returned for a 12-month clinical follow-up assessment.

RESULTS

The UHR group exhibited smaller hippocampal volumes bilaterally, and shape analysis revealed significant inversion in the left ventral posterior hippocampus in the UHR group. Greater inversion in this subregion was related to elevated symptomatology at baseline and increased positive symptoms, negative symptoms, and impaired tolerance to normal stress 12 months later. These results did not hold when left hippocampal volume was used as a predictor instead.

DISCUSSION

This represents the first study to use vertex analysis in a UHR sample and results suggest that abnormalities in hippocampal shape appear to reflect underlying pathogenic processes driving the progression of illness. These findings suggest that examining shape and volume may provide an important new perspective for our conception of brain alterations in the UHR period.

Resting cortisol level, self-concept, and putative familial environment in adolescents at ultra high-risk for psychotic disorders

A growing body of evidence suggests that resting cortisol levels are elevated in patients with schizophrenia and closely tied to symptom severity. However, there is limited research on the biological stress system during the ultra high-risk (UHR) period immediately preceding the onset of psychosis, and cortisol has not been examined in relation to individual characteristics such as self-concept or potential stressors such as putative familial environment in this critical population. In the present study, salivary cortisol samples were collected on 37 UHR and 42 matched control adolescents, and these individuals were assessed with clinical interviews as well as a measure of self-concept. For a subsection of the sample (23 UHR and 20 control adolescents), a participating relative/caretaker was also assessed with an expressed emotion interview designed to gauge psychosocial environment. Consistent with previous studies, UHR participants exhibited elevated resting cortisol levels when compared with controls. In addition, UHR adolescents exhibited increased negative self-concept and their relatives/caretakers endorsed significantly fewer initial positive statements about the participant. Interestingly, a strong trend in the UHR group suggests that higher cortisol levels are associated with higher rates of critical statements from relatives/caretakers. Furthermore, elevated cortisol levels in the participants were associated with increased negative self-concept as well as fewer initial positive comments from relatives/caretakers. Results suggest that hypothalamic-pituitary-adrenal axis (HPA) dysfunction is closely associated with both individual and environmental-level characteristics. Taken together, these findings support a neural diathesis-stress model of psychosis and future studies, designed to examine causal relationships, stand to inform both our understanding of pathogenic processes in the high-risk period as well as early intervention efforts.

Increased postural sway predicts negative symptom progression in youth at ultrahigh risk for psychosis

Impaired ability to maintain an upright posture may reflect impairment in the cerebellum, a critical structure for the fluid coordination of neural information, thought to be disrupted in psychosis. The current study utilized an instrumental measure of posture in individuals at ultrahigh risk (UHR) for psychosis (n=43) and healthy controls (n=44). Positive and negative symptoms were assessed twice over 12months. Results showed that increased postural sway in the UHR group predicted changes in negative symptoms. This study provides an important prospective view on the relationship between cerebellar-sensitive behavior and integral symptoms, which until now has received limited biomarker research.

Neurological soft signs predict abnormal cerebellar-thalamic tract development and negative symptoms in adolescents at high risk for psychosis: a longitudinal perspective

INTRODUCTION

There is an emerging consensus that neurological soft signs (NSS) may not be "soft" at all but rather may reflect neuropathy, particularly in the cerebellum and thalamus. However, our understanding of connective tract abnormalities is limited, and to date, there have been no investigations examining NSS and longitudinal white matter development during the prodrome. Mapping the correlates of NSS in ultrahigh-risk (UHR) youth offers potential for highlighting a viable biomarker as well as for advancing understanding of pathogenic processes during the adolescent risk period.

METHODS

A total of 68 (33 UHR and 35 healthy control) adolescents were assessed with an NSS inventory, structured interviews, and diffusion tensor imaging. Fractional anisotropy (FA) of theoretically relevant cerebellar-thalamic tracts was calculated (left/right superior cerebellar peduncles [SCPs]). Twelve months later, a subset of 30 (15 UHR and 15 control) participants returned for follow-up diffusion tension imaging/clinical assessments.

RESULTS

UHR youth exhibited elevated NSS across domains. While there were no group differences in the integrity of the SCPs at baseline, controls showed a normative increase while the UHR group showed a decrease in FA over 12 months. NSS predicted a longitudinal decrease in cerebellar-thalamic FA and elevations in negative but not positive symptoms 12 months later.

DISCUSSION

Findings of abnormal white matter development provide direct empirical evidence to support prominent neurodevelopmental theories. The predictive relationships between NSS and longitudinal cerebellar-thalamic tract integrity and negative symptom course provide insight into the role of cognitive dysmetria in the high-risk period and inform on a unique biomarker tied to core features underlying psychosis.

Cerebellar Morphology and Procedural Learning Impairment in Neuroleptic-Naive Youth at Ultrahigh Risk of Psychosis

Despite evidence suggesting a role for cerebellar abnormalities in the pathogenesis of psychosis, the structure has yet to receive attention in individuals at ultrahigh risk for psychosis (UHR). Accumulating research has suggested that the cerebellum helps modulate cognition and movement, domains in which UHR individuals show impairment; understanding putative markers of risk, such as structural abnormalities and behavioral correlates, is essential. In this study, participants underwent a high-resolution structural brain scan and participated in a pursuit rotor experiment. Cerebellar regions associated with movement (anterior cerebellum) and cognition (crus I) were subsequently analyzed. UHR participants showed impaired performance on the pursuit rotor task, learned at a slower rate, and showed smaller cerebellar volumes compared with control participants. Left crus I volume was significantly associated with poor rate of learning. The present results suggest that cerebellar abnormalities and their behavioral correlates (poor learning and motor control) precede the onset of psychosis.
