RESUMEN

Individuals at clinical high risk for psychosis (CHR) report a strong desire for psychoeducation, and clinical guidelines recommend psychoeducation in early psychosis care. Although several CHR psychoeducation models have been developed, additional research is needed to establish the effectiveness of these models. The goal of this study was to conduct a pilot trial of the Brief Educational Guide for Individuals in Need (BEGIN). BEGIN is a brief structured psychoeducation intervention designed to educate CHR individuals on symptoms and treatment options. We conducted a feasibility and pilot study of 25 CHR individuals (60% female, Mage = 20.6, 64% non-White, 52% Hispanic/Latino) identified via the Structured Interview for Psychosis Risk Syndromes. Qualitative interviews were administered to learn about their experience and analyzed using iterative thematic analysis. Participants (n = 12) completed pre- and post-BEGIN self-report measures to assess factors that influence treatment engagement, including CHR knowledge and motivation for therapy. Data were analyzed using Hedges' g effect sizes and paired samples t tests. The intervention completion rate (83%) and therapeutic alliance were high. Qualitative themes and quantitative measures converged on similar results showing how CHR individuals were impacted by receiving psychoeducation via BEGIN, including increased CHR knowledge (g = 1.37), competence to monitor symptoms (g = 0.53), hope (g = 0.87), and motivation for therapy (g = 0.46). This study demonstrated the feasibility, acceptability, and potential benefits of the BEGIN CHR psychoeducation model, including enhancing motivation for treatment. The flexible but standardized format can facilitate BEGIN's implementation and dissemination.This pilot study found that the Brief Educational Guide for Individuals in Need (BEGIN), a standardized five-session psychoeducation intervention for individuals at clinical high risk for psychosis (CHR), was feasible, acceptable, and enhanced mental health literacy and motivation for subsequent treatment. Clinicians can utilize the BEGIN intervention to ensure the empathic provision of psychoeducation when disclosing patients' CHR status. Future research with a larger sample will establish efficacy and the development of a clinician training to facilitate implementation (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMEN

BACKGROUND: Basic self-disturbance, or anomalous self-experiences (ASEs), is a core feature of the schizophrenia spectrum. We propose a novel method of natural language processing to quantify ASEs in spoken language by direct comparison to an inventory of self-disturbance, the Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE). We hypothesized that there would be increased similarity in open-ended speech to the IPASE items in individuals with early-course psychosis (PSY) compared with healthy individuals, with clinical high-risk (CHR) individuals intermediate in similarity. METHODS: Open-ended interviews were obtained from 170 healthy control participants, 167 CHR participants, and 89 PSY participants. We calculated the semantic similarity between IPASE items and "I" sentences from transcribed speech samples using S-BERT (Sentence Bidirectional Encoder Representation from Text). Kolmogorov-Smirnov tests were used to compare distributions across groups. A nonnegative matrix factorization of cosine similarity was performed to rank IPASE items. RESULTS: Spoken language of CHR individuals had the greatest semantic similarity to IPASE items when compared to both healthy control (s = 0.44, p < 10-14) and PSY (s = 0.36, p < 10-6) individuals, while IPASE scores were higher among PSY than CHR group participants. In addition, the nonnegative matrix factorization approach produced a data-driven domain that differentiated the CHR group from the others. CONCLUSIONS: We found that open-ended interviews elicited language with increased semantic similarity to the IPASE by participants in the CHR group compared with patients with psychosis. This demonstrates the utility of these methods for differentiating patients from healthy control participants. This complementary approach has the capacity to scale to large studies investigating phenomenological features of schizophrenia and potentially other clinical populations.

RESUMEN

Suicidal ideation (SI) is prevalent among individuals at clinical high-risk for psychosis (CHR). Natural language processing (NLP) provides an efficient method to identify linguistic markers of suicidality. Prior work has demonstrated that an increased use of "I", as well as words with semantic similarity to "anger", "sadness", "stress" and "lonely", are correlated with SI in other cohorts. The current project analyzes data collected in an SI supplement to an NIH R01 study of thought disorder and social cognition in CHR. This study is the first to use NLP analyses of spoken language to identify linguistic correlates of recent suicidal ideation among CHR individuals. The sample included 43 CHR individuals, 10 with recent suicidal ideation and 33 without, as measured by the Columbia-Suicide Severity Rating Scale, as well as 14 healthy volunteers without SI. NLP methods include part-of-speech (POS) tagging, a GoEmotions-trained BERT Model, and Zero-Shot Learning. As hypothesized, individuals at CHR for psychosis who endorsed recent SI utilized more words with semantic similarity to "anger" compared to those who did not. Words with semantic similarity to "stress", "loneliness", and "sadness" were not significantly different between the two CHR groups. Contrary to our hypotheses, CHR individuals with recent SI did not use the word "I" more than those without recent SI. As anger is not characteristic of CHR, findings have implications for the consideration of subthreshold anger-related sentiment in suicidal risk assessment. As NLP is scalable, findings suggest that language markers may improve suicide screening and prediction in this population.

RESUMEN

Psychoeducation is recommended in the treatment of patients with schizophrenia and has been shown to improve satisfaction with mental health service and treatment adherence, reduce relapse and hospital readmission rates, and enhance functioning and quality of life. Youth at clinical high risk for psychosis (CHR) may also benefit from receiving psychoeducation as part of their treatment. The goal of this study was to conduct a scoping review to map out the existing literature on psychoeducation for CHR individuals, including content, utilization, and benefits, in order to identify areas for future research and clinical care. Following PRISMA guidelines, we conducted a systematic search of electronic databases (MEDLINE, Embase, PsycINFO, Scopus, and Web of Science Core Collection) to identify literature through 02/25/2022 that provided data or significant commentary about the provision of psychoeducation to CHR individuals. After screening titles and abstracts, four co-authors assessed full-text articles for eligibility. Thirty-three studies were included in the review. Psychoeducation is recommended in the treatment of CHR individuals, is a preferred treatment option among CHR individuals, and many CHR programs report offering psychoeducation. However, details about the psychoeducational content and method of delivery are notably absent from recommendations and reports on the provision of CHR psychoeducation in real-world settings. We identified two brief and structured CHR psychoeducation interventions and one longer-term psychoeducational multifamily group model for CHR that show feasibility and promise, though they have not yet undergone randomized trials to evaluate effectiveness of the psychoeducation. We also identified several comprehensive CHR interventions that included an explicit psychoeducation module, though the unique role of the psychoeducational component is unknown. Despite being recommended as a critical component of treatment for CHR individuals and preferred by CHR individuals, the ways in which psychoeducation are being delivered to CHR individuals in real-world practice is still largely ambiguous. Rigorous evaluations of psychoeducation treatment models are needed, as well as investment from clinical programs to facilitate the implementation and dissemination of standardized psychoeducation for CHR individuals.

RESUMEN

Background: The COVID-19 pandemic is expected to increase stress and mental health symptoms. We present the case of a young man at risk for psychosis who has paradoxically shown symptomatic and functional improvement as a result of circumstances produced by COVID-19. These changes were unexpected given the client's persistent mental health struggles in the year leading up to the COVID-19 outbreak in the United States and the expectation of an exacerbation of psychotic-like symptoms. Methods: This report is based on clinical assessments and the client's first-person account during the height of the pandemic when stay at home orders were in place. Results: During the pandemic, the client demonstrated increased agency by taking on more responsibility at home and obtaining part-time employment. He showed improvement in his mood and relationships with others, had less symptom-related distress, and significantly reduced his cannabis use. The client interpreted these improvements in terms of changing his mindset toward more adaptive thoughts and engaging in healthy coping skills such as praying, reading, and healthy eating. Conclusions: This case highlights the importance of fostering agency in clients during a time of crisis and ensuring that clinicians be aware of potential biases about mental health symptom exacerbation.

RESUMEN

Resilience research has documented the ability to cope with traumatic and stressful situations and/or retain functioning given certain risk factors in the context of psychosis. In this study, we conducted the first systematic review of the literature on psychosis-like experiences (PLEs) and resilience. Fifteen articles (from 11 unique study samples) from 10 countries were included in this systematic review, with a total of 11,937 unique study participants. Inclusion criteria were broad, capturing a wide range of individuals with PLEs who have not yet experienced threshold psychosis, such as individuals in the general population with elevated self-reports of PLEs, as well as clinical groups diagnosed by clinician interviews (i.e., clinical- or ultra-high-risk for psychosis [CHR or UHR]). For this review, studies needed to include research aims and empirical research related to resilience, and use an established or author-defined measure of psychological and/or social resilience. Data reporting quality was assessed with the Strengthening the Reporting of Observational Studies in Epidemiology and place of residence, race/ethnicity/culture/language, occupation, gender/sex, religion, education, socioeconomic status, social capital (PROGRESS) guidelines. Study aims and measurement of key variables varied widely, and all studies were cross-sectional. In 73% of the studies, resilience was inversely associated with PLEs or psychosis risk status (e.g., CHR or UHR). Results related to specific resilience subscales were mixed. Author-defined resilience was typically related to internal/psychological resources. Future research, particularly longitudinal research involving multidimensional measurement of resilience (e.g., internal and external factors), along with well-defined theoretical models, are necessary before drawing firm conclusions on resilience and PLEs. We propose a dynamic, multifaceted, developmentally appropriate, and culturally sensitive model of resilience for future research. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMEN

Language deficits are prevalent in psychotic illness, including its risk states, and are related to marked impairment in functioning. It is therefore important to characterize language impairment in the psychosis spectrum in order to develop potential preventive interventions. Natural language processing (NLP) metrics of semantic coherence and syntactic complexity have been used to discriminate schizophrenia patients from healthy controls (HC) and predict psychosis onset in individuals at clinical high-risk (CHR) for psychosis. To date, no studies have yet examined the construct validity of key NLP features with respect to clinical ratings of thought disorder in a CHR cohort. Herein we test the association of key NLP metrics of coherence and complexity with ratings of positive and negative thought disorder, respectively, in 60 CHR individuals, using Andreasen's Scale of Assessment of Thought, Language and Communication (TLC) Scale to measure of positive and negative thought disorder. As hypothesized, in CHR individuals, the NLP metric of semantic coherence was significantly correlated with positive thought disorder severity and the NLP metrics of complexity (sentence length and determiner use) were correlated with negative thought disorder severity. The finding of construct validity supports the premise that NLP analytics, at least in respect to core features of reduction of coherence and complexity, are capturing clinically relevant language disturbances in risk states for psychosis. Further psychometric study is required, in respect to reliability and other forms of validity.

RESUMEN

OBJECTIVE: Qualitative research can shed light on the subjective experiences of individuals at clinical high risk (CHR) for psychosis, complement quantitative research, broaden our understanding of experiencing CHR, and inform intervention development. The aim of this study was to explore life experiences of individuals at CHR through qualitative research. METHOD: Participants were 37 individuals at CHR (20 male, 17 female) aged 16-34 (Mage = 23.32 ± 5.26), and 16 healthy controls (HCs; 7 male, 9 female) aged 18-34 (Mage = 25.37 ± 4.05). Qualitative data were obtained through open-ended interviews (30-45 min). No a priori hypotheses were made, and thematic analyses were used to develop themes. RESULTS: Four major themes and one subtheme related to identity were identified through the iterative thematic analysis: defining a self-concept (with a subtheme of creativity), identity development/formation, feeling different from others, and change from a former self. Over 80% of the CHR cohort spontaneously discussed topics related to their identity, compared to 38% of HCs. HCs only reported content within the defining a self-concept theme, while the CHR group reported content within all themes. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The present study demonstrates that identity formation is a major process for youth in general and that psychosis experiences can make this process more challenging. CHR participants spontaneously brought up multiple themes related to identity in open-ended interviews, suggesting the relevance of this topic in this population. Clinicians should continue to probe identity-related concerns on an individual basis and research should focus on integrating this framework into the conceptualization and treatment of CHR.

RESUMEN

AIM: Identification of individuals with psychosis risk (PR) through screening and specialized assessment is becoming more widespread in an effort to promote early intervention and improve recovery outcomes. PR individuals report interest in psychoeducation, though such interventions are currently lacking. Our goal was to develop a structured PR psychoeducation intervention grounded in theory and stakeholder feedback. METHODS: By following a step-by-step intervention development model, we identified relevant conceptual frameworks, developed the content and format, and obtained stakeholder feedback. This process resulted in a 5-session PR psychoeducation intervention, Brief Educational Guide for Individuals in Need (BEGIN), with content conveyed visually via a slideshow presentation. PR individuals (n = 5) and parents of PR individuals (n = 5) reviewed BEGIN's content and format, and provided feedback through semi-structured qualitative interviews. Major themes were identified through iterative thematic analysis. RESULTS: PR individuals and parents had a positive impression of BEGIN's materials and step-by-step format and psychoeducation about the PR condition. They indicated that the intervention was likely to encourage agency. PR participants emphasized the importance of a patient's decision regarding whether their family member(s) should participate in BEGIN. Parents reported that BEGIN is an important first step in treatment and offers a safe therapeutic environment. Feedback was then utilized to modify the intervention. CONCLUSIONS: BEGIN is desired by consumers and may lay the foundation for future engagement with treatment by facilitating agency. A feasibility trial is underway and future studies are needed to measure outcomes (e.g., treatment engagement) and evaluate BEGIN as an evidence-based PR psychoeducation model.

RESUMEN

Aberrant pauses are characteristic of schizophrenia and are robustly associated with its negative symptoms. Here, we found that pause behavior was associated with negative symptoms in individuals at clinical high risk (CHR) for psychosis, and with measures of syntactic complexity-phrase length and usage of determiners that introduce clauses-that we previously showed in this same CHR cohort to help comprise a classifier that predicted psychosis. These findings suggest a common impairment in discourse planning and verbal self-monitoring that affects both speech and language, and which is detected in clinical ratings of negative symptoms.

RESUMEN

Slow oscillations and spindle activity during non-rapid eye movement sleep have been implicated in memory consolidation. Closed-loop acoustic stimulation has previously been shown to enhance slow oscillations and spindle activity during sleep and improve verbal associative memory. We assessed the effect of closed-loop acoustic stimulation during a daytime nap on a virtual reality spatial navigation task in 12 healthy human subjects in a randomized within-subject crossover design. We show robust enhancement of slow oscillation and spindle activity during sleep. However, no effects on behavioral performance were observed when comparing real versus sham stimulation. To explore whether memory enhancement effects were task specific and dependent on nocturnal sleep, in a second experiment with 19 healthy subjects, we aimed to replicate a previous study that used closed-loop acoustic stimulation to enhance memory for word pairs. The methods used were as close as possible to those used in the original study, except that we used a double-blind protocol, in which both subject and experimenter were unaware of the test condition. Again, we successfully enhanced slow oscillation and spindle power, but again did not strengthen associative memory performance with stimulation. We conclude that enhancement of sleep oscillations may be insufficient to enhance memory performance in spatial navigation or verbal association tasks, and provide possible explanations for lack of behavioral replication.

RESUMEN

Direct recordings from the human brain have historically involved epilepsy patients undergoing invasive electroencephalography (iEEG) for surgery. However, these measurements are temporally limited and affected by clinical variables. The RNS System (NeuroPace, Inc.) is a chronic, closed-loop electrographic seizure detection and stimulation system. When adapted by investigators for research, it facilitates cognitive testing in a controlled ambulatory setting, with measurements collected over months to years. We utilized an associative learning paradigm in 5 patients with traditional iEEG and 3 patients with chronic iEEG, and found increased hippocampal gamma (60-100 Hz) sustained at 1.3-1.5 seconds during encoding in successful versus failed trials in surgical patients, with similar results in our RNS System patients (1.4-1.6 seconds). Our findings replicate other studies demonstrating that sustained hippocampal gamma supports encoding. Importantly, we have validated the RNS System to make sensitive measurements of hippocampal dynamics during cognitive tasks in a chronic ambulatory research setting.
