Supporting Student Mental Health With the Safespace Generative AI Chatbot: Mixed Methods Feasibility Study

Background: Generative artificial intelligence (GenAI) chatbots have the potential to provide personalized mental health support to individuals at scale. Objective: This study evaluates the feasibility and usage patterns of the Safespace GenAI chatbot, an artificial intelligence (AI)–driven smartphone app that offers a large language model–powered interactive chatbot to support mental health. Methods: Using a mixed methods approach, we explored baseline attitudes toward GenAI chatbots and chatbot usage patterns, conducted a qualitative content analysis of participants’ experiences, and descriptively assessed patterns related to preintervention depressive symptoms. The study included an initial sample of 42 university students, 20 of whom actively used the chatbot over 2 to 4 weeks, generating 286 user-chatbot interactions. Results: Preintervention surveys indicated that the majority of participants anticipated that the chatbot would be helpful (27/42, 64%) and that they trusted its privacy safeguards (39/42, 93%). Usage patterns suggested that the highest levels of interaction occurred early in the morning and late at night, when peer and professional support may be inaccessible. The qualitative analysis indicated that participants appreciated using the chatbot for reflection as a blended-care tool between their counseling sessions, while also naming technical barriers and specific design needs required to sustain engagement. In addition, our exploratory analyses descriptively showed that participants with elevated depression scores engaged in emotional disclosure during 99% (38 sessions with 8 participants) of their sessions, compared to 84% (26 sessions of 12 participants) of those with low symptoms. Due to the small sample size, future adequately powered studies are needed to inferentially examine these observed patterns. Conclusions: These findings provide initial insights into the usage and engagement dynamics of the Safespace GenAI chatbot and highlight directions for future research to optimize GenAI-driven mental health interventions.

First-in-Human Stem Cell Therapy Trial for Huntington’s Disease Begins at UCI Health

The world’s first in-human embryonic stem cell-derived clinical trial for Huntington’s disease has launched at UCI Health, the clinical arm of the University of California, Irvine. The Phase Ib/IIa trial will evaluate the safety of hNSC-01 neural stem cells derived from embryonic stem cells delivered to the brain by a specialized neurological mapping and targeting stereotactic system.

Huntington’s disease is a fatal, progressive genetic disorder that gradually destroys brain cells. It usually begins between the ages of 35 and 50 with symptoms that include involuntary movements, difficulty thinking and planning daily tasks, and mood changes such as depression. If successful, this therapy could prolong independent living and significantly reduce long-term care costs.

“This clinical trial highlights the important role that an interdisciplinary academic and clinical team together with the HD families, plays in advancing medicine,” said Leslie M. Thompson, PhD, professor of psychiatry and human behavior at UC Irvine. “We are grateful to our patients and their incredible families for their bravery to provide hope for others with very few options.”

The first patient received the intervention at UCI Health Irvine (home to Orange County’s first adult bone marrow/stem cell transplant and cellular therapy program) in May. A second patient is scheduled to receive the intervention in July.

“The first patient intervention went very well. To date, they haven’t reported any serious adverse events,” said Ravi Rajmohan, MD, UCI Health neurologist. “This trial may help us move one step closer to a future with available treatments that could potentially slow the progression of Huntington’s disease.”

The therapy, hNSC-01, uses pluripotent neural stem cells derived from embryonic stem cells, which were manufactured through the UC Davis GMP facility. In animal studies, the cells have been shown to protect existing brain cells, replace lost cells, rebuild impaired brain circuits, release helpful proteins, such as brain-derived neurotrophic factor (BDNF), and reduce harmful protein accumulations that damage brain cells. The stem cells were also shown to be safe over long periods in mice.

The clinical trial will enroll 21 people ages 18 to 65 with early-stage Huntington’s disease. Twelve participants will be enrolled into a Phase Ib dose-escalation group and nine in a Phase IIa expansion group.

The stem cells are implanted during a roughly six-hour surgical procedure done under general anesthesia. While lying face down in an MRI scanner, the patient receives stem cells implanted directly into the striatum deep in the brain, using a purchased proprietary therapy-enabling platform for navigation and surgical delivery. Damage to the striatum, which is responsible for motor control, decision-making, motivation and more, causes Huntington’s disease symptoms. Subjects will be closely monitored for safety as well as preliminary signs of potential benefit.

The clinical trial is made possible by a $12 million grant from the California Institute of Regenerative Medicine (CIRM), and the trial is coordinated through the UC Irvine Alpha Clinic.

Global research landscape, knowledge structure, and emerging trends in adverse childhood experiences and personality disorders: a bibliometric analysis

BackgroundThe relationship between adverse childhood experiences (ACEs) and personality disorders (PDs) has attracted sustained attention in psychiatry, psychology, and public health. Existing studies have mainly examined epidemiological associations, specific PDs diagnoses, or mechanisms, whereas bibliometric evidence mapping the field’s knowledge structure and thematic evolution remains limited. This study aimed to characterize trends, contributors, collaboration networks, core themes, and frontiers in ACEs–PDs research.MethodsEnglish-language publications on ACEs and PDs were retrieved from Web of Science Core Collection, Scopus, and PubMed from inception to December 31, 2025. After year screening, document-type filtering, and deduplication, 5,084 records were included. Bibliometric analyses were performed using R, VOSviewer, and CiteSpace. The merged dataset was used to examine annual trends, countries/regions, institutions, authors, journals, and keyword co-occurrence, while WoSCC records were used for co-citation analysis, keyword clustering, and burst detection.ResultsACEs–PDs research showed sustained growth, with a marked increase after 2000. The United States occupied a central position in publication output, citation impact, and international collaboration, while the United Kingdom, Germany, Canada, the Netherlands, and Australia also showed strong influence. Harvard University, the University of London, and Ruprecht Karls University Heidelberg were leading institutions; Zanarini M, Fonagy P, Schmahl C, Paris J, and Kleindienst N were key contributors. Influential journals mainly covered psychiatry, personality disorders, child maltreatment, trauma, and developmental psychopathology. Keyword analyses identified childhood adversity, personality disorder, borderline personality disorder, depression, childhood sexual abuse, and post-traumatic stress disorder as core themes. VOSviewer and CiteSpace analyses indicated that hotspots have expanded from childhood abuse, PDs diagnosis, and psychiatric comorbidity to emotion dysregulation, non-suicidal self-injury, social support, functional connectivity, early intervention, and mechanism validation. Highly cited publications revealed a knowledge base centered on childhood abuse/trauma, borderline personality disorder, psychiatric comorbidity, emotion regulation, and neurobiological mechanisms.ConclusionThis study maps development and knowledge structure of ACEs–PDs research. Findings suggest a shift from exposure–outcome association studies toward comorbidity, intermediate phenotypes, neurobiological mechanisms, and clinical translation. Future research should strengthen longitudinal and cross-cultural designs, consider ACE type, timing, duration, and severity, and integrate neuroimaging, inflammatory, epigenetic, and clinical-course phenotypes.

Prevalence of depression in patients with advanced cancer receiving palliative care: a meta-analysis of self‐report instruments

BackgroundAlthough the prevalence of depression in patients with advanced cancer receiving palliative care has been widely reported, the estimates vary substantially. This meta-analysis aimed to determine the pooled prevalence of depression in patients with advanced cancer receiving palliative care and identify its potential moderating factors.MethodsA comprehensive literature search was conducted in PubMed, Web of Science, Scopus, Embase, Cochrane Library, CINAHL, and PsycINFO from inception to April 1, 2026. We calculated pooled prevalence estimates using a random-effects model and assessed heterogeneity using the I² statistic. Subgroup analyses and meta-regression were performed to explore potential sources of heterogeneity.ResultsA total of 29 studies comprising 6054 patients with advanced cancer receiving palliative care were included, yielding a pooled prevalence of depression of 50.9% (95% CI: 41.2-60.5%). Subgroup analyses and meta-regression showed that the pooled prevalence varied significantly by study design and assessment tool.ConclusionsOur findings indicated that depression was very prevalent in patients with advanced cancer receiving palliative care. However, the pooled estimate should be interpreted with caution because the extremely high statistical heterogeneity remained largely unexplained, even after conducting subgroup analyses and meta-regression. Furthermore, the adoption of suitable assessment tools and the implementation of valid screening and care strategies are essential to alleviate emotional distress in this vulnerable group.Systematic review registrationPROSPERO, identifier CRD420261368352

Psychotherapy initiation is associated with discontinuation of psychotropic medications without dose escalation: a ten-year real-world cohort study (2014-2024)

BackgroundIncreasing psychotropic prescribing has raised concerns about long-term safety and regimen complexity in mental health care. Although psychotherapy is an established treatment, its role in medication optimization and psychotropic medication reduction in real-world practice across patient subgroups remains insufficiently characterized.ObjectiveTo evaluate whether initiation of psychotherapy is associated with short-term changes in psychotropic medication exposure and regimen complexity, and to examine differences by sex, age, and diagnostic category. Methods: A retrospective cohort study was conducted using anonymized pharmacy dispensing data from the Mental Health Service of Hospital Marina Baixa (Alicante, Spain) between 2014 and 2024. Patients with at least one active prescription for a benzodiazepine or antidepressant within 90 days before psychotherapy initiation were included. Psychotropic exposure was compared in symmetric 90-day pre- and post-therapy windows using number of active agents, total Defined Daily Doses, and prevalence of benzodiazepine and antidepressant use, with stratified analyses by sex, age group, and diagnosis.ResultsThe cohort comprised 86,502 patients and 20.76 million dispensations. The median number of psychotropic medications decreased from 5 to 2 (p < 0.001), while total dose remained stable (median Defined Daily Dose ≈ 21.7; p = 0.999). Benzodiazepine use declined from 87.6% to 67.5% and antidepressant use from 81.8% to 68.8% (both p < 0.001). Men were more likely than women to discontinue benzodiazepines (odds ratio 1.27, 95% confidence interval 1.13–1.43), and simplification increased with age (median reduction −1 in <18 years to −4 in ≥65 years). The largest benzodiazepine reductions occurred in depressive, personality, and episodic mood disorders (−23 to −27 percentage points).ConclusionsIn routine public mental health care, psychotherapy initiation is associated with substantial simplification of psychotropic treatment regimens without increasing overall medication dose, supporting a potential role in facilitating rational medication simplification.

Cognitive-attitudinal factors predict CBT-I enrollment willingness in Chinese sleep clinic patients: a knowledge-attitudes-practices survey

BackgroundDespite strong evidence for cognitive behavioral therapy for insomnia (CBT-I), uptake remains constrained by poorly understood cognitive, attitudinal, and practical barriers. This study examined determinants of willingness to enroll in sleep improvement programs among adults at risk of sleep disorders—including insomnia, obstructive sleep apnea, and comorbid psychological distress—attending a tertiary sleep clinic in China.MethodsA cross-sectional knowledge-attitudes-practices survey was conducted among 2,661 adults attending the sleep and behavioral medicine outpatient clinic at Ganzhou Hospital-Nanfang Hospital, Southern Medical University, Ganzhou, Jiangxi, China, between February 2022 and June 2025. Willingness to enroll in a structured sleep improvement program was assessed alongside sleep health knowledge, perceived need, CBT-I versus medication effectiveness beliefs, telehealth acceptability, clinical severity (Insomnia Severity Index, Epworth Sleepiness Scale, STOP-Bang), psychological symptoms (PHQ-2, GAD-2), perceived barriers, and sociodemographic characteristics. Multivariable logistic regression identified independent predictors of willingness to enrollment, with secondary analyses evaluating model discrimination and testing prespecified interactions.ResultsAmong 2,661 participants (median age 45 years, 56.5% female, median ISI = 13), 1,386 (52.1%) expressed willingness to enroll. Univariable comparisons showed no significant differences between willing and not-willing groups across demographics, clinical characteristics, or barriers (all p>0.05). However, multivariable modeling revealed that when considered simultaneously, cognitive-attitudinal factors emerged as significant independent predictors, suggesting complex interactions rather than simple bivariate associations. In multivariable models, perceived need (OR = 1.20, 95% CI: 1.16–1.25, p<0.001), beliefs that CBT-I is more effective and durable than sleep medication (OR = 1.12, 95% CI: 1.08–1.16, p<0.001), sleep health and treatment knowledge (assessed by a six-item knowledge score) (OR = 1.09, 95% CI: 1.05–1.13, p<0.001), and anxiety symptoms (OR = 1.07, p=0.005) positively predicted willingness. Paradoxically, depression symptoms (OR = 0.94, p<0.001) and insomnia severity (OR = 0.93, p<0.001) inversely predicted willingness. Model discrimination was modest (AUC = 0.543, 95% CI: 0.504–0.590). Time (mean 3.54) and cost (3.44) were most severe barriers but showed no independent association with willingness (p>0.05).ConclusionCognitive-attitudinal factors (perceived need, CBT-I beliefs, knowledge) independently predicted enrollment willingness, whereas demographics and practical barriers did not. Depression and insomnia severity paradoxically reduced willingness, creating an inverse care law. However, poor model discrimination and measurement of stated willingness rather than actual enrollment limit conclusions. Prospective validation and motivational enhancement strategies for patients with depression are needed.
