A feasibility and pilot trial of the Brief Educational Guide for Individuals in Need (BEGIN): Psychoeducation for individuals at risk for psychosis.

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).

Differential Expression of Anomalous Self-Experiences in Spontaneous Speech in Clinical High-Risk and Early-Course Psychosis Quantified by Natural Language Processing.

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.

ChatGPT and Bard exhibit spontaneous citation fabrication during psychiatry literature search.

ChatGPT (Generative Pre-Trained Transformer) is a large language model (LLM), which comprises a neural network that has learned information and patterns of language use from large amounts of text on the internet. ChatGPT, introduced by OpenAI, responds to human queries in a conversational manner. Here, we aimed to assess whether ChatGPT could reliably produce accurate references to supplement the literature search process. We describe our March 2023 exchange with ChatGPT, which generated thirty-five citations, two of which were real. 12 citations were similar to actual manuscripts (e.g., titles with incorrect author lists, journals, or publication years) and the remaining 21, while plausible, were in fact a pastiche of multiple existent manuscripts. In June 2023, we re-tested ChatGPT's performance and compared it to that of Google's GPT counterpart, Bard 2.0. We investigated performance in English, as well as in Spanish and Italian. Fabrications made by LLMs, including erroneous citations, have been called "hallucinations"; we discuss reasons for which this is a misnomer. Furthermore, we describe potential explanations for citation fabrication by GPTs, as well as measures being taken to remedy this issue, including reinforcement learning. Our results underscore that output from conversational LLMs should be verified.

Linguistic correlates of suicidal ideation in youth at clinical high-risk for psychosis.

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.
