Synergistic interaction between pay-it-forward incentives and recreational drug use on hepatitis B virus and hepatitis C virus testing among men who have sex with men in China.

OBJECTIVES: Pay-it-forward incentives effectively promote hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among men who have sex with men (MSM) by offering free testing and donation opportunities. This study aims to explore the interaction between pay-it-forward incentives and recreational drug use on HBV and HCV testing uptake among Chinese MSM. METHODS: We pooled data from two pay-it-forward studies that aimed to promote dual HBV and HCV testing among MSM in Jiangsu, China. We explored factors associated with hepatitis testing uptake in the two study groups and examined the interaction between pay-it-forward incentives and recreational drug use on hepatitis testing uptake. RESULTS: Overall, 511 MSM participated in these two studies, with 265 participants in the pay-it-forward incentives group and 246 participants in the standard-of-care group. Among these participants, 59.3% in the pay-it-forward incentive group and 24.8% in the standard-of-care group received dual HBV and HCV testing, respectively. In the pay-it-forward incentives group, participants who used recreational drugs in the past 12 months (adjusted OR (AOR)=1.83, 95% CI 1.09 to 3.06) were more likely to receive dual HBV and HCV testing, compared with those who never used recreational drugs, whereas in the standard-of-care group, those who used recreational drugs were less likely to receive dual HBC and HCV testing (AOR=0.38, 95% CI 0.18 to 0.78). MSM with higher community connectedness (AOR=1.10, 95% CI 1.00 to 1.21) were also more likely to receive hepatitis testing with pay-it-forward incentives. There was a synergistic interaction on both the multiplicative (ratio of ORs=4.83, 95% CI 1.98 to 11.7) and additive scales (the relative excess risk of interaction=2.97, 95% CI 0.56 to 5.38) of pay-it-forward incentives and recreational drug use behaviours on dual HBV and HCV testing uptake among MSM. CONCLUSION: Pay-it-forward incentives may be particularly useful in promoting hepatitis testing among MSM who use recreational drugs.

The Influence of Behavioral Sciences on Adherence to Physical Activity and Weight Loss in Overweight and Obese Patients: A Systematic Review of Randomized Controlled Trials.

In recent years, weight gain and reduced physical activity in the general population have contributed to the development of obesity and other health problems; on the other hand, studies in behavioral sciences have been used to modify behaviors for a healthier life, so the objective of this study was to identify the evidence of interventions in behavioral sciences on adherence to physical activity and weight loss in obese patients. This systematic review study is based on a search of the electronic databases PubMed, Web of Science, Scopus, and Cochrane. Studies assessed the evidence from intervention studies that assessed the influence of intervention studies of behavioral sciences on public health. The articles were published between 2013 and 2023. The systematic search of the databases identified 2951 articles. The review analyzed 10 studies. Behavioral science interventions presented evidence through strategies such as multicomponent interventions, lottery and financial incentives, message framing, message framing with financial incentive and physical activity, and psychological satisfaction, demonstrating results in weight loss and maintenance and increased physical activity. This study presents scientific evidence through healthy behavior change methodologies, and future studies can explore these strategies in conjunction with public health technologies in the search for public-private partnerships to promote physical activity in adults.

Racial and Ethnic Composition of Departments of Health Policy & Management and Health Education & Behavioral Sciences.

The diversity of racial/ethnic representation in the health services and policy research (HSPR) workforce plays a crucial role in addressing the health needs of underserved populations. We assessed changes (between 2012 and 2022) in the racial/ethnic composition of students and faculty from departments of Health Policy & Management (HPM) and Health Education & Behavioral Sciences (HEBS) among the Association of Schools and Programs of Public Health member institutions. We analyzed annual data from over 40 institutions that reported student and faculty data in 2012 and 2022 within each department. Racial/ethnic populations included American Indian/Alaska Native (AI/AN), Asian, Hispanic, Native Hawaiian/Pacific Islander (NH/PI), Black, White, Unknown, and Multiracial. We conducted analyses by department and examined racial/ethnic composition by student status, degree level, faculty rank, and tenure status. We found statistically significant increases in Black assistant professors (HPM and HEBS) and tenured faculty (HPM), Hispanic graduates and tenure-track faculty (HPM), Asian professors (HPM: full and tenured, HEBS: associate and tenured), and Multiracial students and graduates (HPM and HEBS). Statistically significant decreases were observed in White professors (HPM: assistant and full, HEBS: all ranks) and tenure-track faculty (HPM and HEBS), AI/AN associate professors and tenured faculty (HEBS), Hispanic associate professors (HPM), Asian assistant professors (HEBS), and NH/PI students (HPM and HEBS). Our findings highlight the importance of increasing racial/ethnic representation. Strategies to achieve this include facilitating workshops to raise awareness about the structural barriers encountered by Hispanic faculty, providing research support, evaluating promotion processes, establishing more pathway programs, and fostering interdisciplinary academic environments studying AI/AN or NH/PI populations.

Receptiveness to monkeypox vaccines and public health communication strategies among gay, bisexual and other men who have sex with men in Singapore: cross-sectional quantitative and qualitative insights.

OBJECTIVES: Monkeypox (mpox) was declared as a global health emergency by the WHO, with most reported cases disproportionately involving gay, bisexual and other men who have sex with men (GBMSM). This study explored the willingness of Singaporean GBMSM to receive mpox vaccines and engage in changes to sexual behaviour, and analysed the factors influencing both decisions. METHODS: An online cross-sectional study was disseminated through community groups and Grindr from September to October 2022 among GBMSM in Singapore, where we surveyed respondents' demographics, stigma associated with mpox, perceived risks of sexually transmitted infections (STIs) and changes to sexual behaviours in response to mpox. Descriptive statistics and multivariable linear and logistics regression analyses, as well as thematic analysis of data, were also conducted. RESULTS: 237 GBMSM community members responded to the survey, with the majority being receptive to vaccine and 67.5% indicating changes to sexual behaviour in view of rising mpox infections. Predictors of vaccine receptivity among GBMSM included self-perceived mpox risk (adjusted OR (aOR)=0.44, 95% CI 0.07, 0.82) and self-perceived STI risk (aOR=0.39, 95% CI 0.03, 0.76). Predictors for changes to sexual behaviour included self-perceived mpox stigma (aOR=1.17, 95% CI 1.08, 1.27), self-perceived mpox risk (aOR=1.22, 95% CI 1.03,1.44), age (aOR=0.96, 95% CI 0.93, 1.00) and race (aOR=0.31, 95% CI 0.10, 0.93). In the thematic analysis, respondents raised concerns about vaccine effectiveness, side effects, cost and privacy. CONCLUSIONS: Our findings suggest that the rise in mpox infections have prompted changes to GBMSM's sexual practices. In general, GBMSM are willing to receive the mpox vaccine but are concerned about the physical and social consequences of uptake. These concerns should be addressed when vaccines are released.

Violent Video Recognition by Using Sequential Image Collage.

Identifying violent activities is important for ensuring the safety of society. Although the Transformer model contributes significantly to the field of behavior recognition, it often requires a substantial volume of data to perform well. Since existing datasets on violent behavior are currently lacking, it will be a challenge for Transformers to identify violent behavior with insufficient datasets. Additionally, Transformers are known to be computationally heavy and can sometimes overlook temporal features. To overcome these issues, an architecture named MLP-Mixer can be used to achieve comparable results with a smaller dataset. In this research, a special type of dataset to be fed into the MLP-Mixer called a sequential image collage (SIC) is proposed. This dataset is created by aggregating frames of video clips into image collages sequentially for the model to better understand the temporal features of violent behavior in videos. Three different public datasets, namely, the dataset of National Hockey League hockey fights, the dataset of smart-city CCTV violence detection, and the dataset of real-life violence situations were used to train the model. The results of the experiments proved that the model trained using the proposed SIC is capable of achieving high performance in violent behavior recognition with fewer parameters and FLOPs needed compared to other state-of-the-art models.

Reflective Engagement With a Digital Physical Activity Intervention Among People Living With and Beyond Breast Cancer: Mixed Methods Study.

BACKGROUND: People living with and beyond breast cancer can face internal barriers to physical activity (eg, fatigue and pain). Digital interventions that promote psychological acceptance and motivation may help this population navigate these barriers. The degree to which individuals (1) adhere to intervention protocols and (2) reflect on and internalize intervention content may predict intervention efficacy. OBJECTIVE: The objective of this study was to characterize the nature of reflective processes brought about by an 8-week acceptance- and mindfulness-based physical activity intervention for insufficiently active survivors of breast cancer (n=75). Furthermore, we explored the potential utility of a metric of reflective processes for predicting study outcomes. METHODS: Of the intervention's 8 weekly modules, 7 (88%) included an item that asked participants to reflect on what they found to be most useful. Two coders conducted directed content analysis on participants' written responses. They assessed each comment's depth of reflection using an existing framework (ranging from 0 to 4, with 0=simple description and 4=fundamental change with consideration of social and ethical issues). The coders identified themes within the various levels of reflection. We fit multiple linear regression models to evaluate whether participants' (1) intervention adherence (ie, number of modules completed) and (2) the mean level of the depth of reflection predicted study outcomes. RESULTS: Participants were aged on average 57.2 (SD 11.2) years, mostly non-Hispanic White (58/75, 77%), and mostly overweight or obese (54/75, 72%). Of the 407 responses to the item prompting personal reflection, 70 (17.2%) were rated as reflection level 0 (ie, description), 247 (60.7%) were level 1 (ie, reflective description), 74 (18.2%) were level 2 (ie, dialogic reflection), 14 (3.4%) were level 3 (ie, transformative reflection), and 2 (0.5%) were level 4 (ie, critical reflection). Lower levels of reflection were characterized by the acquisition of knowledge or expressing intentions. Higher levels were characterized by personal insight, commentary on behavior change processes, and a change of perspective. Intervention adherence was associated with increases in self-reported weekly bouts of muscle-strengthening exercise (B=0.26, SE 0.12, 95% CI 0.02-0.50) and decreases in sleep disturbance (B=-1.04, SE 0.50, 95% CI -0.06 to -2.02). The mean level of reflection was associated with increases in psychological acceptance (B=3.42, SE 1.70, 95% CI 0.09-6.75) and motivation for physical activity (ie, integrated regulation: B=0.55, SE 0.25, 95% CI 0.06-1.04). CONCLUSIONS: We identified a useful method for understanding the reflective processes that can occur during digital behavior change interventions serving people living with and beyond breast cancer. Intervention adherence and the depth of reflection each predicted changes in study outcomes. Deeper reflection on intervention content was associated with beneficial changes in the determinants of sustained behavior change. More research is needed to investigate the relations among digital behavior change intervention use, psychological processes, and intervention efficacy.

Exploring Students' Compassion Outcomes within a Dental School's Tobacco Treatment Training Program: A pilot study.

Purpose It has been suggested that compassion may decrease as students progress through their health care education and into clinical practice. The purpose of this pilot study was to determine whether an immersive curriculum thread of tobacco use disorder (TUD) cessation methodology, including behavioral techniques and communication skills, was associated with any change in dental hygiene and dental students perceived levels of compassion.Methods Dental hygiene (DH) and dental (DS) students (n=300) who had experienced an immersive TUD curriculum from West Virginia University were invited to complete the Sussex-Oxford Compassion Scale-Toward Others (SOC-O) online survey during the academic years 2022-2023. Possible scores on the SOC-O ranged from 20 (no or low compassion) to 100 (high compassion). The SOC-O scores for students who did not have clinical experience and limited TUD content (first- and second-year DH and DS students) were compared with SOC-O scores of students who had clinically applied the immersive tobacco cessation curriculum thread (third and fourth year DH and DS students) using t-tests.Results A total of seventy DH and DS students completed the SOC-O survey for a response rate of 23.3%. The overall mean SOC-O score was 83.0 for participants who lacked clinical experience (DH1, DH2, DS1, DS2) and 85.8 for participants with clinical experience using the TUD content (DH3, DH4, DS3, DS4) (p >0.05). For the SOC-O subscale analysis, both groups were similar in the recognition of suffering, universality of suffering, empathy/compassion for a person suffering, tolerance of uncomfortable feelings, and action/motivation to act to alleviate suffering.Conclusion A high level of perceived compassion among dental hygiene and dental students was associated with an immersive behavioral sciences curriculum thread for the assessment/treatment of TUD. Perceived levels of compassion were maintained for participants with and without clinical experience. Additional focus on compassion philosophy research within educational methodology is needed to maintain and improve compassion outcomes in the health care professions.

Interdisciplinary lessons and recommendations for the evaluation of replicability in behavioral sciences.

As the scientific community becomes aware of low replicability rates in the extant literature, peer-reviewed journals have begun implementing initiatives with the goal of improving replicability. Such initiatives center around various rules to which authors must adhere to demonstrate their engagement in best practices. Preliminary evidence in the psychological science literature demonstrates a degree of efficacy in these initiatives. With such efficacy in place, it would be advantageous for other fields of behavioral sciences to adopt similar measures. This letter provides a discussion on lessons learned from psychological science while similarly addressing the unique challenges of other sciences to adopt measures that would be most appropriate for their field. We offer broad considerations for peer-reviewed journals in their implementation of specific policies and recommend that governing bodies of science prioritize the funding of research that addresses these measures.

Depressive symptoms and their correlates among predoctoral dental students in the United States.

OBJECTIVE: To investigate the prevalence of self-reported depressive symptoms among predoctoral dental students in the United States and examine potential correlates. METHODS: A survey was emailed to all 66 dental schools in the United States, inviting them to distribute it to their predoctoral students. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Data collection occurred from February to April 2020. Multivariable ordinal logistic regression was used to assess associations between demographic variables and depressive symptom severity category, adjusting for potential confounding. RESULTS: Of an estimated 25,000 predoctoral dental students at the 66 schools, 631 students from 21 schools completed the survey. A total of 24.1% were categorized as having minimal or no depressive symptoms, 33.6% as having mild depressive symptoms, and 42.3% as having moderate, moderately severe, or severe depressive symptoms. Gender (p = 0.015) and race/ethnicity (p = 0.002) were significant predictors of severity, adjusting for other variables. Students identifying as female had higher odds of self-reporting greater depressive severity symptoms compared with students identifying as male. Students identifying as African American/Black (non-Hispanic) and Asian/Pacific Islander had higher odds of self-reporting greater depressive severity symptoms compared with students identifying as White. CONCLUSION: There is evidence of a high prevalence of depressive symptoms among predoctoral dental students in the United States. Demographic variables may be risk indicators within this population. Approaches to reduce depressive symptoms among US predoctoral dental students are needed.

THE 3P MODEL AND ORAL HEALTH IMPACT: DEMONSTRATING THE IMPORTANCE OF BEHAVIORAL AND SOCIAL SCIENCES IN THE FUTURE OF EVIDENCE-BASED DENTISTRY.

Oral health impact or oral health related quality of life is an increasingly important and well-known metric in dental care and research. There have been recent calls for greater integration of the behavioral and social sciences into oral health research and practice, including the need for frameworks and theories to guide this work. One such framework for understanding the role of predisposing, precipitating, and perpetuating biopsychosocial mechanisms in health and disease is the "3P" model. Here, the 3P model is described and applied to case examples to help understand the development and maintenance of oral health impact. Additionally, this paper outlines how this conceptualization using the 3P model and oral health impact makes way for greater integration of behavioral interventions to prevent, mitigate, or treat the negative impact that oral, craniofacial, or dental disease may have on individuals. Doing this allows for a broadening of what evidence-based dentistry means for the future and provides a roadmap going forward.

Social Cognitive Theory Variables as Correlates of Physical Activity Behavior Among Hispanics With Multiple Sclerosis.

OBJECTIVE: To examine the association between social cognitive theory (SCT) variables and physical activity (PA) behavior in Hispanic adults with multiple sclerosis (MS). DESIGN: Observational, survey study. SETTING: General community. PARTICIPANTS: Inclusion criteria: (a) age 18 years or older, (b) self-identify as Hispanic or Latino, (c) diagnosis of MS, and (d) English or Spanish as primary language. Two hundred forty-three individuals opened the survey, 24 individuals did not meet inclusion criteria, and 66 individuals were excluded due to not completing any of the SCT variable measures (N=153). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): PA was measured using the Godin Leisure Time Exercise Questionnaire (GLTEQ) total and Health Contribution Scores (HCS). SCT variables included standard measures of exercise self-efficacy, planning, goal setting, outcome expectations, social support, and functional impairment. RESULTS: The final sample included 153 participants with a mean (SD) age of 43 (11) years, 78% identified as women, 57% were employed, and 63% had a college degree or higher. The mean (SD) MS disease duration was 11 (9) years, 74% of participants reported relapsing remitting MS, and median (interquartile range) Patient Determined Disease Steps (PDDS) score was 3.0 (3.0). Significant correlations were observed between all SCT variables and both GLTEQ total and GLTEQ HCS scores (P<.001). Forward stepwise regression with Akaike's Information Criterion (AICC) identified PDDS, age, exercise planning, exercise self-efficacy, and exercise goal setting as the most appropriate covariates and SCT variables to include in a multivariable model examining independent contributions on GLTEQ HCS scores. The multivariable, linear regression analysis indicated that PDDS (Standardized B=-.280, P<.001), exercise planning (Standardized B=.214, P<.05), and exercise self-efficacy (Standardized B=.183, P<.05) explained 42.4% of variance in GLTEQ HCS scores. CONCLUSIONS: This study provides a contribution to the literature by identifying SCT variables that correlate with PA behavior among Hispanics with MS that may guide the creation of culturally appropriate PA programs.

Exploring and describing current behavioral and social sciences curricula in predoctoral dental programs.

PURPOSE: To maintain accreditation status, predoctoral dental programs in the United States and Canada are required to train future dentists in the fundamentals of behavioral sciences. Each program independently determines how to fulfill this task, and little information exists on the consistency of training across programs. The purpose of this study was to identify the range of topics currently taught in predoctoral dental programs in the United States and Canada, who teaches them, and the modes of instruction and assessment. METHODS: Invitations to complete an online survey were emailed to faculty responsible for, or familiar with, the behavioral sciences curricula at 75 predoctoral dental programs in the United States and Canada. Questions elicited information on behavioral sciences education at each program, including instructor background, topics taught, instructional and assessment methods, and sources of content. RESULTS: Of those invited, 27 (36%) completed surveys. Per the responses, prototypical behavioral sciences programs usually consist of didactic/lecture format teaching, mostly during the first 2 years of the predoctoral program, by a dentist who assesses students using multiple-choice or true/false exams. The results indicated, however, substantial variation in what is taught, how it is taught, who teaches it, and how it is assessed. CONCLUSIONS: While being a requirement for accreditation, this study demonstrated how behavioral and social sciences topics, teaching strategies, and assessments, along with the individuals teaching those topics varied across predoctoral programs. Consistency, coordination, and clinical integration are possible ways of enhancing behavioral science instruction.

A systematic review of educational nutrition interventions based on behavioral theories in school adolescents.

The purpose of this study was to summarize the evidence from studies conducted on adolescents, evaluating educational nutrition interventions for the modification of food consumption through controlled trials based on behavior change theories or models and implemented in school settings. A systematic search was carried out through PubMed and ERIC databases between November and December 2020, and updated in February 2023; English-language keywords were used, and no publication date limits were applied. Two authors independently performed the search, data extraction, data synthesis and risk of bias assessment. Twelve studies meeting the inclusion criteria were included. The interventions were based on different theories; the most used was the Social Cognitive Theory. Eleven of the twelve studies showed favorable modifications in the consumption of at least two of the food groups. Most studies were at low risk of bias, and only one was classified as high risk. It is concluded that educational nutrition interventions based on behavior change theories/models and implemented in the school setting influence positive changes in adolescents eating behavior.

Los cuidados enfermeros de San Juan de Dios según el Modelo de las necesidades humanas de Henderson / Cuidados de enfermagem de São João de Deus segundo o modelo de necessidades humanas de Henderson / Nursing care of Saint John of God according to Henderson's model of human needs

Consulting manuals of the History of Nursing, it can be appreciated how it is from Nightingale when considering the birth of modern or professional Nursing. However, this belief could be a black legend, because before the 19th century there was already awareness of Nursing as a profession, being this initiated by Juan de Dios, the one from Granada, in the Spanish 16th century. For this reason, in this article we have set the objective of describing the care of Juan de Dios following the model of human needs described by Henderson, together with care in agony and post-mortem. To do this, we use the historiographical methodology following the current of the history of mentalities, so that we can go from the past to the present, and vice versa. In the documentary analysis we have been able to observe how what we find today systematized in a theoretical way was already carried out at the beginning of the nursing reform of the Spanish 16th century, being a valid model for current Nursing, since it is found in its being, knowing , and doing, the concepts of the current nursing metaparadigm, although not explicitly, since its intention, more than theoretical, was care, although behind it there was a corpus of doctrine independent of other socio-health disciplines.(AU)

Consultando manuales de Historia de la Enfermería, se puede apreciar cómo es a partir de Nightingale cuando se considera el nacimiento de la Enfermería moderna o profesional. Sin embargo, esta creencia podría ser leyenda negra, pues antes del S. XIX ya existía conciencia de Enfermería como profesión, siendo esta iniciada por Juan de Dios, el de Granada, en el S. XVI español. Por ello, en el presente artículo hemos marcado como objetivo el describir los cuidados de Juan de Dios siguiendo el modelo de necesidades humanas descritas por Henderson, junto con los cuidados en la agonía y post-mortem. Para ello, utilizamos la metodología historiográfica siguiendo la corriente de la historia de las mentalidades, de manera que podamos ir del pasado al presente, y viceversa. En el análisis documental hemos podido observar cómo lo que hoy encontramos sistematizado de manera teórica, ya se realizaba en el inicio de la reforma enfermera del S. XVI español, siendo un modelo válido para la Enfermería actual, pues se encuentra en su ser, saber, y hacer, los conceptos del metaparadigma enfermero actuales aunque no de manera explícita, puesto que su intención, más que teórica, era asistencial, aunque detrás de ella hubo un corpus doctrinal independiente a otras disciplinassocio-sanitarias.(AU)

Can cognitive neuroscience solve the lab-dilemma by going wild?

Reproducibility, measurability, and refutability are the foundation of the scientific method applied to empirical work. In the study of animal and human behavior, experimental protocols conducted in the lab are the most reliable means by which scientists can operationalize behaviors using controlled and parameterized setups. However, whether observations in the lab fully generalize in the real world remain legitimately disputed. The notion of "experimental design" was originally intended to ensure the generalizability of experimental findings to real-world situations. Experiments in the wild are more frequently explored and significant technological advances have been made allowing mobile neuroimaging. Yet some methodological limitations remain when testing scientific hypotheses in ecological conditions. Herein, we discuss the limitations of inferential processes derive from empirical observations in the wild. The multi-causal property of an ecological situation often lacks controls, and this major concern may prevent the replication and the reliability of behavioral observations. We discuss the epistemological and historical grounds of the induction process for behavioral and cognitive neurosciences and provide some possible heuristics for In situ experimental designs compatible with psychophysics in the wild.

Framework for Accurate Classification of Self-Reported Stress From Multisession Functional MRI Data of Veterans With Posttraumatic Stress.

Background: Posttraumatic stress disorder (PTSD) is a significant burden among combat Veterans returning from the wars in Iraq and Afghanistan. While empirically supported treatments have demonstrated reductions in PTSD symptomatology, there remains a need to improve treatment effectiveness. Functional magnetic resonance imaging (fMRI) neurofeedback has emerged as a possible treatment to ameliorate PTSD symptom severity. Virtual reality (VR) approaches have also shown promise in increasing treatment compliance and outcomes. To facilitate fMRI neurofeedback-associated therapies, it would be advantageous to accurately classify internal brain stress levels while Veterans are exposed to trauma-associated VR imagery. Methods: Across 2 sessions, we used fMRI to collect neural responses to trauma-associated VR-like stimuli among male combat Veterans with PTSD symptoms (N = 8). Veterans reported their self-perceived stress level on a scale from 1 to 8 every 15 s throughout the fMRI sessions. In our proposed framework, we precisely sample the fMRI data on cortical gray matter, blurring the data along the gray-matter manifold to reduce noise and dimensionality while preserving maximum neural information. Then, we independently applied 3 machine learning (ML) algorithms to this fMRI data collected across 2 sessions, separately for each Veteran, to build individualized ML models that predicted their internal brain states (self-reported stress responses). Results: We accurately classified the 8-class self-reported stress responses with a mean (± standard error) root mean square error of 0.6 (± 0.1) across all Veterans using the best ML approach. Conclusions: The findings demonstrate the predictive ability of ML algorithms applied to whole-brain cortical fMRI data collected during individual Veteran sessions. The framework we have developed to preprocess whole-brain cortical fMRI data and train ML models across sessions would provide a valuable tool to enable individualized real-time fMRI neurofeedback during VR-like exposure therapy for PTSD.
