About
Elizabeth A. Martin is a researcher with a focus on emotional processing, social cognition, and psychosis-related disorders, particularly schizophrenia and schizotypy. Her work extensively explores the neural and behavioral aspects of emotional experience, social anhedonia, and cognitive control in populations at risk for or diagnosed with schizophrenia-spectrum disorders. Martin has contributed to understanding the electrophysiological and psychological mechanisms underlying emotional abnormalities, social functioning, and affective control in these groups. Her research includes investigations into facial emotion perception, affective forecasting, and the role of self-concept clarity and aberrant salience in psychotic-like experiences. Through numerous studies, Martin has examined the interplay between emotional traits, cognitive processes, and social behavior, providing insights into the distinct constructs of social anhedonia and schizotypy. Her work also addresses methodological issues such as measurement invariance across diverse populations and the neural correlates of reward and punishment learning in psychosis risk groups.

preprintOpen access1st authorCorrespondingThe Hierarchical Taxonomy of Psychopathology (HiTOP) is a dimensional approach to understanding mental health, addressing limitations of categorical systems such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD). This study aimed to validate a Mandarin version of the HiTOP Self-Report (HiTOP-SR), with a focus on the Internalizing, Detachment, and Somatoform spectra among a Chinese population. A translation and back-translation process was followed by collaborative item refinement from a team of bilingual and monolingual scholars to ensure both linguistic equivalence and cultural relevance. The final 213-item scale was administered to 1,999 undergraduate students across four Chinese universities, with follow-up assessments conducted five weeks later. The Mandarin HiTOP-SR demonstrated strong psychometric properties, including high internal consistency (α > .70 for 45 scales/subscales), good test-retest reliability (r > .70 for 32 scales/subscales), adequate model fit for 45 scales/subscales, and acceptable discriminant validity (only 13 pairs showed a latent correlation of > .90). Convergent validity was supported by strong correlations with corresponding DSM-5-TR symptom domains. These findings confirm the structural and conceptual alignment of the Mandarin HiTOP-SR with the HiTOP framework. This culturally informed adaptation advances the development of evidence-based, dimensional assessment tools in Chinese contexts and contributes to the global applicability of transdiagnostic models of psychopathology.

articleOBJECTIVE: Clinical high risk for psychosis (CHR-P) is associated with distress, impairment, and elevated risk for developing full-threshold psychosis. Early intervention can improve prognostic outcomes, but limited research has investigated associations between social determinants and mental health care utilization among people at CHR-P. The authors aimed to explore whether distressing positive symptoms, race-ethnicity, immigration, racial discrimination, and social support correlate with mental health care utilization in this population. METHODS: 171). RESULTS: Asian and Black participants were significantly less likely than White participants to report past use of mental health care. Black participants were significantly less likely than White participants to report current use of services. Differences in past service use for Asian and Black participants versus Hispanic/Latinx participants and in current service use for Asian versus White participants approached statistical significance. Trend-level associations suggesting a lower likelihood of service use among immigrant participants were attenuated when household income was accounted for. Across the full sample, distressing positive symptoms significantly predicted current use of services. CONCLUSIONS: Associations between self-reported race-ethnicity and mental health care utilization persisted even when analyses accounted for distressing positive symptoms, social support, and discrimination. As CHR-P research and practice increasingly focus on early intervention, study findings underscore the importance of better understanding contextual factors and social determinants that are associated with mental health service use among youths at CHR-P.

articleOpen accessThe Hierarchical Taxonomy of Psychopathology (HiTOP) provides a dimensional framework for connecting psychological disorders to neural systems/processes. We examined how neurophysiological measures of cognitive-attentional (oddball P300) and perceptual-emotional processing (fear-face N170/P200) relate to dimensions of the HiTOP externalizing spectrum. Employing 666 community participants, we fit a model in which antagonistic externalizing and substance problems subfactors, defined via symptom and questionnaire-scale measures, loaded with a disinhibitory trait scale onto a higher-order externalizing factor. Hierarchical regression was used to evaluate how much observed relations of each neural measure with the two subfactors reflected their unique variance versus their covariance (reflected in the general factor). P300's relations were fully accounted for by the general factor, suggesting that impaired cognitive processing characterizes broad risk for externalizing problems. Neural indicators of sensitivity to others' distress (N170, P200) were uniquely related to antagonistic externalizing. Findings highlight the HiTOP framework's potential to advance biobehavioral understanding of psychopathology.

articleOpen accessPurpose: To identify the needs, preferences, and perspectives of people living with dementia and their carers to inform design and implementation of an in-home respite service. Design/Methodology: Exploratory, interpretivist, pre- implementation qualitative study using Consolidated Framework for Implementation Research. Participants: People living with dementia and carers. Data collection: Multi-person and individual semi-structured interviews. Findings: 15 participants: Four people living with dementia, 11 carers. Carers are exhausted and want a say in the development and delivery of services. People living with dementia and carers need safety, trust in respite staff and in the organisation, consistency, additional supports, and clear, transparent communication. Future directions: Findings will inform in-home dementia respite models of care, better supporting family carers and people living with dementia to age-in-place. Recommendations: provide an orientation session; clear, transparent communication; provide/refer carers to wrap-around supports; ensure consistency including having consistent carers, arrival times, services provided and routines; emergency and scheduled options.

articleOpen accessThe Extractables and Leachables Safety Information Exchange (ELSIE) Consortium added to the sensitization potency analysis of Parris et al. (2023) by including the Product Quality Research Institute (PQRI) extractable and leachable dataset (Johnson et al., 2024; Product Quality Research Institute, 2021). This analysis of the comprehensive E&L dataset showed 5% of chemicals (20/407) had experimental results demonstrating or were predicted to be potent (strong or extreme) sensitizers, supporting the previous conclusion, that potent sensitizers are of low prevalence and are not routinely observed as leachables in pharmaceutical products. By accounting for prevalence of sensitization in the overall E&L dataset, the probability of any potential leachable being more potent than the less than lifetime ICH M7 (10, 20, and 120 μg/day for human exposure of >1-10 years, >1-12 months, and <1 month respectively) and non-mutagenic ELSIE threshold values (35, 110, and 180 μg/day for human exposures of >10 years to lifetime, >1-10 years, and ≤1 year respectively) (Masuda-Herrera et al., 2022) was considered. The M7 and ELSIE thresholds are anticipated to provide ≥95% coverage of induction of sensitization, supporting the use of these thresholds to set the Safety Concern Threshold (SCT).

reviewOpen accessLinking neurobiology to relatively stable individual differences in cognition, emotion, motivation, and behavior can require large sample sizes to yield replicable results. Given the nature of between-person research, sample sizes at least in the hundreds are likely to be necessary in most neuroimaging studies of individual differences, regardless of whether they are investigating the whole brain or more focal hypotheses. However, the appropriate sample size depends on the expected effect size. Therefore, we propose four strategies to increase effect sizes in neuroimaging research, which may help to enable the detection of replicable between-person effects in samples in the hundreds rather than the thousands: (1) theoretical matching between neuroimaging tasks and behavioral constructs of interest; (2) increasing the reliability of both neural and psychological measurement; (3) individualization of measures for each participant; and (4) using multivariate approaches with cross-validation instead of univariate approaches. We discuss challenges associated with these methods and highlight strategies for improvements that will help the field to move toward a more robust and accessible neuroscience of individual differences.

articleOpen accessIndividuals at clinical high risk for psychosis (CHR) have variable clinical outcomes and low conversion rates, limiting development of novel and personalized treatments. Moreover, given risks of antipsychotic drugs, safer effective medications for CHR individuals are needed. The Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ) Program was launched to address this need. Based on past CHR and schizophrenia studies, AMP SCZ assessed electroencephalography (EEG)-based event-related potential (ERP), event-related oscillation (ERO), and resting EEG power spectral density (PSD) measures, including mismatch negativity (MMN), auditory and visual P300 to target (P3b) and novel (P3a) stimuli, 40-Hz auditory steady state response, and resting EEG PSD for traditional frequency bands (eyes open/closed). Here, in an interim analysis of AMP SCZ EEG measures, we assess test-retest reliability and stability over sessions (baseline, month-2 follow-up) in CHR (n = 654) and community control (CON; n = 87) participants. Reliability was calculated as Generalizability (G)-coefficients, and changes over session were assessed with paired t-tests. G-coefficients were generally good to excellent in both groups (CHR: mean = 0.72, range = 0.49–0.85; CON: mean = 0.71, range = 0.44–0.89). Measure magnitudes significantly (p < 0.001) decreased over session (MMN, auditory and visual target P3b, visual novel P3a, 40-Hz ASSR) and/or over runs within sessions (MMN, auditory/visual novel P3a and target P3b), consistent with habituation effects. Despite these small systematic habituation effects, test-retest reliabilities of the AMP SCZ EEG-based measures are sufficiently strong to support their use in CHR studies as potential predictors of clinical outcomes, markers of illness progression, and/or target engagement or secondary outcome measures in controlled clinical trials.

articleOBJECTIVE: Psychotic-like experiences (PLEs) are associated with increased risk for developing psychotic disorders and with perceived need for mental health care. Commonly reported barriers to care among individuals with PLEs are stigma, beliefs about care, and the cost of services. This study aimed to address gaps in understanding this population's decision-making processes regarding mental health care utilization (MHCU). METHODS: Associations between PLEs and perceived need for care, interest in care, and barriers to care among 931 young adults were explored. RESULTS: PLEs were positively associated with self-perceived need for care, a need for care that was perceived by others, and interest in seeking mental health care. Stigma was a commonly reported barrier to care among those with PLEs. CONCLUSIONS: The results suggested that PLEs have an impact on the mental health care decision-making process. Future work should explore the effects of efforts to reduce stigma related to MHCU in this population.
