Effectiveness of transcranial direct current stimulation with and without positive mood induction on worry and transdiagnostic cognitive-emotional processes: A randomized controlled trial.

The present study investigated the effectiveness of transcranial direct current stimulation (tDCS), with and without positive mood induction, on worry and key transdiagnostic cognitive-emotional processes, including attentional bias, working memory, problem solving, and emotion regulation, in individuals with high levels of worry. This single-blind randomized controlled trial included 45 individuals with high levels of worry. After a structured clinical interview, participants were randomly assigned, with gender balancing, to one of three groups: (1) tDCS alone, (2) tDCS combined with positive mood induction, or (3) a sham control group. Outcome measures were administered at three time points (pretest, posttest, and one-month follow-up) and assessed attentional bias (Dot Probe Task), working memory (1-back task), problem solving (Tower of London task), emotion regulation (Gross's Emotion Regulation Questionnaire), and worry severity (Penn State Worry Questionnaire; PSWQ). Repeated-measures ANOVA showed that both active groups (tDCS alone and tDCS + positive mood induction) significantly improved attentional bias, worry, working memory, problem solving, and emotion regulation compared to controls (p < 0.05). The combined intervention produced significantly greater gains than tDCS alone in working memory, problem solving, emotion regulation (p < 0.05), and reductions in attentional bias and worry (p < 0.001). All effects persisted at one-month follow-up (p < 0.05). tDCS reduces worry and attentional bias and enhances cognition and emotion regulation in individuals with high levels of worry. The combined intervention produced larger and more sustained improvements than tDCS alone across the assessed behavioral outcomes. These findings support further investigation of combining tDCS with structured positive mood induction while the mechanisms underlying the additional benefits remain to be established.

Game-Based Intervention for Bullying: Assessing the Efficacy of the REThink Therapeutic Game in Primary School Children.

Children's mental health issues can have a lasting effect into adulthood, including enhanced risks for their social and emotional development, as well as their academic performance and overall behavior. Worldwide nearly 1 billion children are affected by the bullying phenomenon, with social, emotional, and economic consequences. In this vein, our study aimed to analyze the effect of the therapeutic game REThink on the improvement of emotion regulation abilities and the reduction of both bullying behavior and victimization in primary school children. Our sample consisted of 75 children who were voluntarily enrolled by their parents, and randomly assigned to the intervention group (n&#x2009;=&#x2009;38) or to the control group (n&#x2009;=&#x2009;37). They completed the baseline assessment consisting of emotion regulation, irrationality, bullying and victimization behavior measurements, then the children from the intervention group played the therapeutic game REThink. Four&#x2009;weeks later, after completing each level twice, every participant had completed the same questionnaires at the post-test assessment. The results indicated significant changes across victimization for children who were exposed to verbal, physical or social bullying, increased emotional control and lower levels of irrationality, low frustration tolerance to work and demandingness, with small to medium effect size improvements for the REThink game group compared to the control group. The REThink therapeutic game proved to be a promising intervention tool for reducing victimization effects and irrationality, and improving emotion regulation abilities in primary school children. Future research could improve on these results by addressing the timeline stability limit.

The mediating role of protective factors in relationship between caregiving components and psychosocial adjustment among young carers: a meta-analysis.

OBJECTIVE: Higher youth caregiving is associated with poorer psychosocial outcomes in young carers; hence a research priority is to investigate protective factors that mitigate the adverse effects of youth caregiving. This systematic review with meta-analysis examined the relationships among youth caregiving components and young carer psychosocial adjustment and protective factors, as well as the mediating role of the protective factors in the relationship between caregiving components and psychosocial adjustment. METHODS: Three electronic databases were searched until April 2024 and 10,244 unique publications were identified. Following abstract and title screening, 422 publications were subjected to full-text screening and 60 quantitative studies were included in this study. RESULTS: Meta-analytic structural equation modeling (MASEM) results revealed positive direct effects of caregiving responsibilities and caregiving experiences on benefit finding (&#x3b2;&#xa0;=&#xa0;.43, 95% CI [.074, .782], p&#xa0;<&#xa0;.05) and emotion regulation (&#x3b2;&#xa0;=&#xa0;.72, 95% CI [.44, 1.00], p&#xa0;<&#xa0;.001), respectively. However, there was neither a significant direct effect of caregiving components on psychosocial adjustment nor a significant indirect effect of caregiving components on psychosocial adjustment through benefit finding or emotion regulation. CONCLUSION: Findings revealed a need for research into how caregiving contextual factors affect relations among youth caregiving, protective factors, and adjustment.

Does Timing Matter? Age of First Mobile Phone Acquisition and Psychological Outcomes in Middle and Late Adolescence.

The age at which adolescents acquire their first smartphone has decreased markedly in recent years; however, evidence on its long-term effects on psychosocial adjustment remains limited. This study investigated whether age at first mobile phone acquisition is associated with psychosocial functioning in middle and late adolescence, including social integration and competence, emotion regulation difficulties, disordered eating behaviors and problematic social media use (PSMU). The sample comprised 1179 adolescents aged 15-17 years (53.8% female). Linear regression and generalized additive mixed models were used to examine both linear and nonlinear associations, adjusting for age, gender and school clustering. Earlier smartphone acquisition was linearly but weakly associated with greater emotion regulation difficulties, disordered eating and PSMU, even after adjustment for covariates. In contrast, associations with social integration and competence were nonlinear: acquiring a first smartphone between ages 6 and 10 or after age 13 was associated with lower social integration in adolescence, whereas acquisition between ages 11 and 13 was linked to higher social functioning. These findings suggest that the developmental timing of first smartphone access shows a modest association with subsequent psychosocial functioning during middle and late adolescence. Focusing on the timing of access, alongside other demographic and contextual factors, may contribute to a better understanding of digital influences on adolescent well-being.

[Participation of the serotoninergic system of the brain in regulation of emotional reactivity].

Vocalization and aggressiveness reactions were evoked in experiments on male Wistar rats by means of electric shock stimulation. The influence of serotonin- and dopaminergic drugs was studied in parallel on emotional reactivity and serotonin metabolism. It has been found that l-tryptophane depresses while l-Dopa intensifies emotional reactivity and aggressiveness, the latter lowering the level of endogenous serotonin and enhancing its catabolism. L-Dopa, dl-amphetamine, alpha-methyl-Dopa, parachlorophenylalanine and serotonino-blockators--deseryl and lysergide--eliminate the tranquilizing action of tryptophane on emotional reactivity, decreasing serotonin accumulation and intensifying the formation of 5-oxyindolacetic acid.

ADCY2 promoter hypomethylation in adolescents with borderline personality disorder: An RRBS study with targeted BSP replication.

BACKGROUND: Borderline Personality Disorder (BPD) is characterized by emotional dysregulation, impulsivity, and interpersonal instability. Although genetic and environmental contributions to BPD have been investigated, epigenetic correlates in adolescents remain poorly understood. The cyclic adenosine monophosphate (cAMP) signaling pathway is implicated in stress responsivity and emotion regulation, but its epigenetic variation in adolescent BPD remains understudied. METHODS: DNA methylation profiling was performed using Reduced Representation Bisulfite Sequencing (RRBS) in buccal epithelial DNA from adolescents with BPD (n = 15) and healthy controls (HC; n = 15). Differentially methylated regions (DMRs) were identified using metilene, a computational tool for detecting DMRs from bisulfite sequencing data, and subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Associations between methylation signals and borderline personality features were examined. Adenylate cyclase 2 (ADCY2) promoter methylation was examined using targeted bisulfite sequencing PCR (BSP) in an independent cohort (BPD n = 5; HC n = 5). RESULTS: RRBS identified 7641 DMRs between BPD and HC, with enrichment in pathways related to neuronal signaling and synaptic organization. A hypomethylated DMR was detected in the ADCY2 promoter, a gene implicated in cAMP signaling. Lower ADCY2 promoter methylation was associated with greater clinical severity, including emotional dysregulation, borderline traits, anxiety symptoms, and self-injury behaviors (r=-0.71 to -0.83; all p < 0.0001). Hypomethylation of the ADCY2 promoter was replicated in the independent cohort. CONCLUSIONS: This exploratory two-stage epigenetic study suggests that ADCY2 promoter hypomethylation in peripheral buccal epithelial DNA is associated with core symptom dimensions of adolescent BPD. These findings support a role for cAMP-related epigenetic variation in BPD and warrant replication in longitudinal studies.

Mediators of Change in Cognitive Behavioral and Mindfulness-Based Online-Interventions for Hypoactive Sexual Desire Dysfunction in Women.

Low sexual desire is a common sexual problem among women. When it is accompanied by significant personal distress, it may be diagnosed as hypoactive sexual desire dysfunction (HSDD). Both cognitive behavioral therapy (CBT) and mindfulness-based therapy (MBT) are effective treatments for HSDD when delivered in person or online. In this randomized controlled treatment study, CBT and MBT consisted of eight guided self-help modules delivered online, and participants completed measures at pretreatment and after 3, 6, and 12&#x2009;months. Nine variables were examined as potential mediators of treatment outcomes (i.e., sexual desire and sexual distress), namely mindfulness, self-compassion, rumination, body connection, self-consciousness, relationship satisfaction, sexual communication, depression, and anxiety. In total, 212 women diagnosed with HSDD were randomized to either CBT or MBT (Mage&#x2009;=&#x2009;36.3, SD&#x2009;=&#x2009;10.2). Improvements in self-compassion, rumination, body connection, and self-consciousness partially mediated treatment outcomes in at least one of the treatment groups. Mediation effects were mostly small, explaining up to 15% of the total effects. No systematic differences in mediation pathways between CBT and MBT were found. These findings emphasize the importance of emotion regulation, metacognitive processes, and embodiment for the effective treatment of HSDD. Future research should refine treatment components to enhance efficacy and ensure that psychological interventions adequately address common concerns among women with HSDD.

[Participation of the amygdaloid complex in the regulation of insulin and corticoid secretion in emotional stress].

The emotional stress induced in dogs by means of electrodermal stimulation, lowered the blood insulin and increased the corticoids and sugar contents. Bilateral amygdalectomy eliminated the inhibitory effect of the electrodermal stimulation on the insular apparatus and caused a lesser albeit prolonged increase in the blood corticoid content. The blood sugar under these conditions was also somewhat increased. Different effects of separate amygdaloid nuclei on insulin secretion were revealed in acute experiments. The inhibitory effect of amygdaloid nuclei is realised through ventromedial hypothalamic nucleus

[Disorders in the adrenergic innervation of the stomachs of rats with stable regulation of cardiovascular function in the presence of emotional stress].

Changes of arterial pressure and of the frequency of cardiac contractions were analyzed in Wistar rats under acute immobilization stress; stability of the cardiovascular functions under emotional stress was revealed. An increased sensitivity of the adrenergic component of the sympathetic and parasympathetic innervation of the stomach that caused the development of its dystrophic processes was observed. Emotional stress proved to be accompanied by phasic dynamics of disorders in the adrenergic innervation: mobilization in the adrenergic innervation was followed by its exhaustion.

[Endorphins--endogenous peptides with morphine-like effects. 2. Biological importance, clinical apsects].

Since 1974 peptides with opiate-like action both in vivo and in vitro have been isolated from the nervous system of various vertebrates and man. The localization of these peptides (endorphins) within the central and peripheral nervous system reflects the possible biological functions in which they may participate: the response of the CNS to painful stimuli (dorsal horn of the spinal cord, central grey matter, thalamus); the control of emotions (limbic system); the regulation of vegetative functions (medulla oblongata); the response of the body to stress the control of endocrine function (hypothalamus, infundibulum, hypophysis); the control of extrapyramidal motor activity (brain stem) or the control of intestinal motility (intramural nervous plexus). Up-to-date knowledge suggests that the endorphins may function as neurotransmitters, neuromodulators or hormones and that such functions vary according to the special sites of synthesis, storage and action of these various peptides within the body.

[Some problems of a psychiatric care unit in a general hospital. II: Compulsory health treatments (author's transl)].

The new italian law regulating psychiatric treatments (number 180/78) does away with hospitalization for mental diseases in Psychiatric Hospitals. When required, hospitalization occurs only in Psychiatric Care Units attached to General Hospitals. Compulsory Health Treatments (T.S.O from italian "Trattamenti Sanitari Obbligatori") may be enforced whenever the patient refuses to be hospitalized although he needs hospitalization for treatment and there are no alternatives to it. The Authors report on the first seven months of experience in a Psychiatric Care Unit of a General Hospital in Florence where T.S.O. had been made available. The characteristics, places of origin, profession of the 42 patients admitted for T.S.O. have been investigated. Organizational and emotional issues arising from the enforcement of the new regulations and involving the staff are examined; the main issue being the significance of not having participated in the decision for hospitalization although having the responsibility for the patient's staying in the hospital. All these seem to have made more difficult, at least at first, to achieve a thorough psychiatric treatment, whereas it is easier to resort to a mere drug treatment. Possible solutions to ease the situation are put forward.

Foot-shock stress accelerates non-striatal dopamine synthesis without activating tyrosine hydroxylase.

Electric foot-shock stress (20 min) increases DOPAC content in the frontal cortex (by about 80%) and in the nucleus accumbens (by 35%) but not in the striatum. However, foot shock stress failed to modify the kinetic properties of tyrosine hydroxylase (Vmax, Km for DMPH4 cofactor) in any of the above areas. Similar results were obtained in rats in which noradrenergic terminals in the n. accumbens and in the frontal cortex had been eliminated by injection of 6-OH-dopamine into the ascending dorsal noradrenergic bundle. The results support the hypothesis that limbic and cortical DA is involved in emotional states and indicate that DA synthesis may be regulated independently from changes in the kinetics properties of tyrosine hydroxylase.

[Adrenergic response to intense muscular activity in sedentary subjects as a function of emotivity and training].

Seven male sedentary human subjects were studied during intense muscular work (80% of maximal oxygen uptake) performed either for 15 min or until exhaustion (mean duration: 47 +/- 2 min). Plasma catecholamines were estimated before and after the experiment by means of an original fluorimetric assay. Epinephrine or norepinephrine were individually isolated from plasma and assayed in single extracts by a highly sensitive fluorimetric method. Epinephrine and norepinephrine levels as low as 15 ng per liter were detectable by this procedure in human plasma. The adrenergic pattern was found to be greatly different from one subject to another and related to emotivity: the effect of this factor was revealed by the predominance of epinephrine in plasma at rest or under exercise (ratio NA/A less than 1). In nonemotive subjects (ratio NA/A greater than 1 at rest) plasma epinephrine and norepinephrine increased progressively during exercise. Increments after exercise were higher for norepinephrine changes; however, the fact that epinephrine concentrations correlated significantly with norepinephrine suggests a simulataneous and coordinated stimulation of adrenal glands and orthosympathetic nervous system. In emotive subjects (ratio NA/A less than 1 at rest) the apprehension of muscular work promoted a difference in catecholamine responses: norepinephrine release was not affected by subject's anxiety, while epinephrine secretion, already elevated before the test, reached a high degree of magnitude in the first minutes of muscular work, remaining nearly constant until exhaustion. Physical training of nonemotive subjects, during 2 months with two intense exercises by a week, reduced strongly norepinephrine release after exhaustive muscular work. In the same conditions, the adrenal-medullary response was not significantly modified when compared with untrained subjects. Our results suggest that the adrenergic behaviour during exercise is a function of effort intensity to be supplied; catecholamines seem to be important factors in regulating body homeostasy during muscular work in man. In addition, emotive subjects exhibit amplified adrenal-medullary response, which may be related to psychological stimuli.

Advancing nursing education through social and emotional learning: A systematic review guided by the Collaborative for Academic, Social, and Emotional Learning framework.

BACKGROUND: With Generation Z entering the nursing workforce in growing numbers, strengthening social and emotional learning is critical for academic success, professional adaptation, and safe practice. However, the existing evidence remains fragmented because of varied interventions and inconsistent approaches. OBJECTIVES: This systematic review examined (1) the social and emotional learning essential for nursing students and nurses within the Collaborative for Academic, Social, and Emotional Learning framework, (2) their impact on educational and clinical outcomes, and (3) implications for advancing nursing education and practice. METHODS: Following Joanna Briggs Institute methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, five international (PubMed, EMBASE, CINAHL, PsycINFO, Cochrane) and three Korean (RISS, KoreaMed, KMBASE) databases were searched up to June 2025. Eighteen studies involving 2,952 participants met the inclusion criteria, including quasi-experimental quantitative studies, descriptive quantitative studies, qualitative studies, and mixed-methods studies. The methodological quality of the included studies was appraised using the Mixed Methods Appraisal Tool. RESULTS: Within the Collaborative for Academic, Social, and Emotional Learning framework, relationship skills and self-management were the most frequently studied competencies, emphasizing teamwork, communication, and stress regulation. Self-awareness and social awareness were underexplored, despite their importance in empathy, resilience, and reflective practice. Responsible decision-making was the least studied competency, despite its importance in ethical reasoning. Social and emotional learning was consistently associated with enhanced adaptation, communication, leadership, relationships, and clinical performance. Effective strategies included blended learning, simulation, reflective activities, and mentorship, which are aligned with Generation Z's learning preferences. CONCLUSION: Although social and emotional learning integration is associated with improvements in educational and clinical outcomes in nursing, current research has largely centered on relational and stress-related competencies while underrepresenting responsible decision-making. To cultivate reflective, empathetic, and ethically grounded nurses, curricula should integrate social and emotional learning through a balanced and structured approach. REGISTRATION: This study was registered on PROSPERO (ID: CRD420251005683).
