IntroductionAdolescent depression poses a major public health concern with substantial clinical and societal implications. Both internet-delivered cognitive behavioural therapy (ICBT) and internet-delivered psychodynamic therapy (IPDT) have shown efficacy, but questions remain regarding long-term efficacy and cost-effectiveness. The present study presents a 12-month follow-up and cost-comparison from a randomized controlled trial (RCT) comparing ICBT and IPDT for adolescent depression.MethodsParticipants were 272 adolescents aged 15–19 with a primary diagnosis of major depressive disorder. The primary outcome was depressive symptoms measured with the QIDS-A17-SR while the secondary outcome was anxiety symptoms measured with the GAD-7. Costs were assessed both by comparing costs of treatment and healthcare use 12-month post-treatment using the TIC-P.ResultsResults were stable at the 12-month follow up compared to treatment endpoint, for both depressive and anxiety symptoms. There were no significant group differences at the 12-month follow-up. There were no differences in treatment costs or in costs for healthcare use one-year post-treatment.DiscussionThis study suggests that treatment gains from IPDT and ICBT for adolescent depression remain stable during a 12-month follow-up period, with no differences between the treatments one-year post-treatment. Furthermore, it suggests comparable costs for the treatments. Interpretation of health-care use data was restricted due to the COVID-19 pandemic taking place during the follow-up period. This adds to the literature suggesting that ICBT and IPDT can be seen as viable alternatives for treating adolescent depression. More research into the long-term effects and cost-effectiveness is needed.
Impact of Prescribed and Self-Selected Music Interventions on Stress, Sleep, Heart Rate Variability, and Brain Connectivity in Surgeons Using 7-Tesla Functional Magnetic Resonance Imaging and Wearable Actigraphy: Multimodal Feasibility Randomized Controlled Trial
<strong>Background:</strong> Stress, sleep deprivation, and burnout are significant safety risks for acute care surgeons, negatively impacting performance, well-being, and clinical outcomes. <strong>Objective:</strong> This pilot randomized controlled trial aimed to measure neurophysiological effects of prescribed music (PM) and self-selected music (SSM) on surgeon stress, burnout, and neurophysiological responses using a multimodal protocol that integrated functional magnetic resonance imaging (fMRI), wearable biosensor monitoring, and psychological self-assessments. <strong>Methods:</strong> Full-time attending surgeons at a quaternary care hospital were invited to participate in a 3-armed trial (1:1:1 block allocation). Intervention groups were instructed to listen to 30 minutes (minimum 15 minutes) of either PM or SSM daily at bedtime for 6 weeks, reflecting real-world conditions. PM comprised original compositions based on elements promoting perceived relaxation from a prior study. The control arm avoided music in the 30 minutes before bed. Allocation was concealed from the recruiting investigator; the fMRI technicians, the statistician, and lead investigators were blinded until analyses were completed. Functional connectivity patterns were measured using fMRI at baseline and 6 weeks while participants listened to simulated intensive care unit noise, PM, and SSM. Secondary outcomes included continuous actigraphy for sleep quality and self-reported anxiety, sleep quality, and burnout using validated scales (State-Trait Anxiety Inventory, Pittsburgh Sleep Quality Index, and Maslach Burnout Inventory). <strong>Results:</strong> A total of 22 surgeons were assessed; demands of fMRI and data collection schedule led 3 to decline and 2 (allocated to PM) not to finish baseline measures; 6 PM, 5 SSM, and 6 controls received allocated intervention; 2 PM participants were withdrawn for nonadherence and missing follow-up data and 1 control missed follow-up collection due to scheduling (final analysis set after missing data: PM: n=4, SSM: n=5, control: n=5). One control participant experienced transient vertigo in fMRI. Trends in fMRI data indicated that both intervention groups experienced less negative emotional arousal and anxiety, with physical tension reduced in the PM group. The PM group exhibited reduced stress response in the frontal lobes when exposed to intensive care unit alarms, suggesting diminished attentional response to the high-stress auditory environment, compared to control. However, lack of statistical significance and baseline variability entail cautious interpretation. Observations of sleep quality were mixed, and no statistically significant differences in stress surveys were observed. <strong>Conclusions:</strong> Both music interventions trended toward positive changes in neurophysiological responses, suggesting potential benefits in reducing surgeon stress. However, due to the small sample, mixed or nonsignificant results, and the exploratory nature of this study, findings should be considered preliminary. Further research with larger, diverse cohorts is required to confirm trends, refine both the intervention approach and recruitment strategies, and determine whether objective compositional elements or personally selected music drive the mechanisms of potential positive effects. <strong>Trial Registration:</strong> ClinicalTrials.gov NCT05980429; https://clinicaltrials.gov/study/NCT05980429
Effect of low-intensity focused ultrasound on hippocampus of alcohol addicted mice: a preliminary study
Alcohol addiction is a chronic relapsing brain disorder characterized by significant neurobiological changes, particularly within the hippocampus, which mediates emotional regulation and reward-seeking behavior. Previous studies have shown that alcohol-induced neuronal injury contributes to withdrawal-associated anxiety and persistent alcohol preference. This study investigated the therapeutic effects of low-intensity focused ultrasound (LIFU) on the hippocampus in a mouse model of alcohol addiction. Twenty-six male C57BL/6 mice were allocated to an alcohol-exposed group (n = 20) and a control group (n = 6). Following a 28-day modeling period, the alcohol group was randomly subdivided into a therapy group and a sham group. The therapy group received LIFU treatment, while the sham group underwent an identical procedure with the ultrasound transducer powered off. After seven days of treatment, the therapy group exhibited less severe anxiety symptoms upon alcohol withdrawal and a reduced preference for alcohol compared to the sham group. The brain-derived neurotrophic factor (BDNF) concentration was significantly lower in the therapy group than in the sham group, but did not differ significantly from the control group. Hippocampal HE staining revealed more pronounced degeneration and apoptosis of granule cells in the dentate gyrus (DG) region in the sham group relative to the therapy group. These preliminary findings suggest that LIFU may modulate alcohol addiction by mitigating hippocampal neuronal injury.
Anxiety among Chinese primary school teachers under the “double reduction” policy: prevalence and associated factors
ObjectivesThe implementation of the “Double Reduction” Policy in China has raised concerns about increased anxiety levels among primary school teachers. However, the prevalence of anxiety symptoms and the factors associated with them remain unclear. This study aims to investigate the prevalence and correlates of anxiety among primary school teachers under this policy.MethodsA cross-sectional survey was conducted from September to October 2022 among primary school teachers in 15 cities across China. Participants completed a series of questionnaires administered via WeChat to assess anxiety symptoms and potential related factors, including perceived stress, sociodemographic characteristics, and job-related variables. Anxiety and perceived stress were measured using the Generalized Anxiety Disorder-7 (GAD-7) and 10-item Perceived Stress Scale (PSS-10), respectively.ResultsOverall, 44.5% (1,423/3,199) of teachers reported at least mild anxiety symptoms. Among them, 56.43%, 25.30% and 18.27% had mild, moderate, and severe anxiety, respectively. In the final logistic regression model, five variables remained independently associated with anxiety: education level (master’s degree or above: OR = 2.781, 95% CI: 1.858–4.163), income dissatisfaction (OR = 1.487, 95% CI: 1.205–1.834), intermediate professional title (OR = 1.372, 95% CI: 1.084–1.738), younger age (OR = 0.979, 95% CI: 0.966–0.993), and perceived stress (OR = 1.489, 95% CI: 1.443–1.538).ConclusionAnxiety was prevalent among primary school teachers during the implementation of the “Double Reduction” Policy. Higher education level, income dissatisfaction, intermediate professional title, younger age, and elevated perceived stress were significant risk factors for anxiety. Therefore, interventions focusing on stress management and occupational support may help improve teachers’ mental well-being.
Psychometric validation of the revised Chinese version of the Dimensional Anhedonia Rating Scale in psychiatric outpatients
ObjectiveTo refine the Chinese version of the Dimensional Anhedonia Rating Scale (DARS) and evaluate the psychometric properties of the Revised Chinese DARS (RC-DARS) in a large sample of first-visit psychiatric outpatients.MethodsThe study was conducted in two sequential phases at a specialized psychiatric hospital. In Phase I (n = 277), the existing Chinese DARS underwent semantic and cultural refinement in accordance with ISPOR and TRAPD guidelines, incorporating cognitive interviews and back-translation procedures. In Phase II (n = 788), the RC-DARS was administered alongside the Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Pittsburgh Sleep Quality Index (PSQI), and the MMPI Suicide Ideation Subscale (MMPI-SI). Exploratory and confirmatory factor analyses were conducted using common-factor extraction and the WLSMV estimator for ordinal indicators. Internal consistency, gender-based measurement invariance, and convergent validity were evaluated.ResultsExploratory analyses supported a four-factor domain structure. Confirmatory factor analysis demonstrated good model fit for the domain-based model (χ²/df = 3.81, CFI = 0.98, TLI = 0.97, RMSEA = 0.08, SRMR = 0.05), with substantially superior fit relative to an alternative reward-processing model. Internal consistency was excellent (Cronbach’s α = 0.95; McDonald’s ω = 0.96). Multi-group analyses supported configural, metric, and scalar invariance across gender (ΔCFI < 0.01). RC-DARS total scores were significantly negatively correlated with depressive symptoms (r = −0.443), anxiety (r = −0.317), sleep disturbance (r = −0.494), and suicide risk (r = −0.312) (all p <.001). Individuals with severe depressive symptoms exhibited significantly lower RC-DARS scores than those below the clinical threshold.ConclusionsThe RC-DARS demonstrates robust psychometric properties in a first-visit outpatient sample. The revision primarily enhances semantic precision and structural differentiation without materially altering score distributions. The scale may serve as a refined instrument for dimensional assessment of anhedonia in similar clinical contexts, pending longitudinal and multi-site validation.
Two faces of police stress: Spanish validation of operational and organizational PSQ scales
IntroductionPolice officers face multiple psychosocial risks stemming from operational and organizational aspects of their work. The Police Stress Questionnaire (PSQ) includes operational (PSQ-Op) and organizational (PSQ-Org) versions to assess these stressors. This study aimed to validate both versions in a sample of Mossos d’Esquadra, examining their factorial structure, reliability, and convergent and discriminant validity.MethodsExploratory and confirmatory factor analyses were conducted to examine the internal structure of the PSQ-Op and PSQ-Org. Internal consistency was evaluated using reliability indices. Convergent and discriminant validity were assessed through correlations with measures of anxiety, depression, and coping strategies.ResultsBoth PSQ-Op and PSQ-Org showed an essentially unidimensional structure, indicating that each scale measures a coherent latent construct. Operational and organizational stress remained distinct domains. Both scales exhibited high reliability and adequate psychometric properties. Subtle gender differences were noted in the perception of specific stressors.DiscussionThese findings support the validity and reliability of the PSQ-Op and PSQ-Org for assessing psychosocial risks among Spanish police officers. The scales can inform interventions targeting workplace stress prevention and the promotion of organizational well-being, emphasizing the need to address operational and organizational stressors separately.
Role of TRPC1 in the pathogenesis of depression induced by traumatic brain injury
BackgroundTraumatic brain injury (TBI) is one of the leading causes of mortality and disability, with many patients developing long-term sequelae. Depression is among the most common psychiatric complications following TBI, yet its underlying mechanisms remain unclear. Transient receptor potential canonical 1 (TRPC1) has been implicated in neurological disorders, but its role in post-TBI depression is not well understood.MethodsA controlled cortical impact (CCI) model was used to induce moderate TBI in mice. At 4 weeks post-injury, depressive-like behaviors were assessed using the tail suspension test (TST), forced swim test (FST), and sucrose preference test (SPT). Subsequently, reactive astrocytes and microglia were quantified, along with the expression of inflammatory cytokines, in the ipsilateral hippocampus. Synaptic function was also evaluated.ResultsBehavioral tests revealed that TBI mice exhibited significant depressive- and anxiety-like behaviors at 4 weeks post-injury. Concurrently, TRPC1 expression was downregulated in the ipsilateral hippocampus, accompanied by reduced levels of synaptic-associated proteins, elevated pro-inflammatory cytokines, and increased reactive astrocytes and microglia. Further experiments demonstrated that TRPC1 overexpression attenuated neuroinflammation, restored synaptic function, and ameliorated depressive-like behaviors in TBI mice.ConclusionThis study suggests that TBI may trigger depression by downregulating TRPC1, thereby promoting neuroinflammation and synaptic dysfunction. Conversely, TRPC1 overexpression mitigates these effects, highlighting its potential as a therapeutic target for post-TBI depression.

Early tinnitus burden and subjective hearing are candidate markers of 2-year quality of life after cochlear implantation in single-sided deafness
BackgroundCochlear implantation is a common treatment for adults with single-sided deafness (SSD), but patient-reported benefits vary. The relationships among tinnitus burden, perceived hearing ability, psychological distress, disease-specific health-related quality of life, and whether early postoperative outcomes predict later results are not well understood.ObjectiveThis study explores how disease-specific quality of life relates to tinnitus burden, hearing, stress, depression, and anxiety after cochlear implantation in SSD. It also seeks early markers linked to 2-year outcomes.MethodsThis secondary complete-case analysis was based on a previously reported prospective longitudinal SSD cohort. Of 70 adults with postlingual SSD, 36 (51.4%) had complete Nijmegen Cochlear Implant Questionnaire (NCIQ) data at baseline and at 6 months, 1 year, and 2 years after unilateral cochlear implantation and were included. Additional measures included the Tinnitus Questionnaire (TQ), Oldenburg Inventory (OI), PerceivFed Stress Questionnaire (PSQ), General Depression Scale (ADS-L), Generalized Anxiety Disorder 7-item scale (GAD-7), and Freiburg Monosyllable Test (FMT) at 65 dB. Timepoint-specific correlations with the NCIQ were analyzed using Spearman’s rank correlations. Exploratory multivariable analyses employed linear regression on rank-transformed variables to assess whether baseline and 6-month patient-reported profiles were associated with 2-year NCIQ outcomes. Longitudinal within-patient comparisons were conducted as a secondary descriptive analysis.ResultsHigher NCIQ scores were linked to lower tinnitus burden and better hearing across all assessments. Associations with depression and anxiety persisted, while connections with perceived stress emerged after surgery. At baseline, higher tinnitus burden was associated with lower 2-year NCIQ scores. At 6 months, higher tinnitus is still associated with lower 2-year NCIQ scores, whereas better hearing is associated with higher 2-year NCIQ scores. Early postoperative improvement was followed by stabilization over 2 years.ConclusionImprovement in health-related quality of life after cochlear implantation in adults with SSD is complex and extends beyond hearing alone. Tinnitus was the most consistent negative factor, while improved subjective hearing at 6 months was associated with better outcomes at 2 years. These results support a structured, multidimensional approach to patient-reported follow-up after cochlear implantation in SSD and suggest that early postoperative patient-reported status may serve as an early candidate marker for later quality-of-life outcomes.
Direct and indirect associations of hypochondriasis with suicidality in psychiatric outpatients: mediating roles of anxiety and depression
IntroductionAlthough both hypochondriasis and suicidality are common in psychiatric patients and related to anxiety and depression, their association in psychiatric patients remains unclear. This study investigated the direct association of hypochondriasis with suicidality and the indirect associations via anxiety and depression in psychiatric patients.MethodsClinical records of 5484 psychiatric outpatients were reviewed. Hypochondriasis, Suicidality, Anxiety, and Depression were evaluated using the hypochondriasis item of the Hamilton Depression Rating Scale, the suicidality item of the 17-item Hamilton Depression Rating Scale (HAM-D17), the Hamilton Anxiety Rating Scale (HAM-A), and the 6-item subscale of the Hamilton Depression Rating Scale (HAM-D6), respectively. The associations among Hypochondriasis, Suicidality, Anxiety, and Depression were examined using a parallel mediation model. The model was estimated using the lavaan package in R with 10, 000 bootstrap resamples, adjusted for age and sex. Moderation by age and sex was also investigated.ResultsSignificant positive indirect associations via Anxiety (point estimate = 0.05, 95% CI [0.03, 0.06]) and Depression (point estimate = 0.17, 95% CI [0.15, 0.19]) were observed between Hypochondriasis and Suicidality. Conversely, the direct association between Hypochondriasis and Suicidality was also significant but in a negative direction (B = −0.16, p <.001). As the total indirect association was stronger than the direct association, the total association of Hypochondriasis with Suicidality was significantly positive (B = 0.05, p = 0.002). The negative direct association of Hypochondriasis with Suicidality was significantly stronger in younger patients (interaction term = 0.004, p <.001).ConclusionAnxiety and depression mediated the association between hypochondriasis and increased suicidality. In contrast, hypochondriasis was associated with decreased suicidality after accounting for the mediators. As the indirect association was stronger than the direct association, hypochondriasis was associated with increased suicidality overall. The direct association between hypochondriasis and decreased suicidality was stronger in younger patients.
