School Refusal Behaviors: The Roles of Adolescent and Parental Factors.

School refusal behaviors in adolescents have deleterious immediate and long-term consequences and are associated with mental ill-health such as anxiety and depression. Understanding factors that place youth at higher risk of school refusal behavior may assist in developing effective management approaches. We investigated parental and adolescent factors that may be associated with school refusal behaviors by specifically focusing on the role of parental and adolescent emotion dysregulation, their anxiety and depression, and parental rearing style. First, we hypothesized that adolescents with school refusal behaviors, as well as their parents, will report higher levels of emotion dysregulation, anxiety, and depression compared to their counterparts without school refusal behaviors. Furthermore, we hypothesized that multivariate models testing the role of parental and child factors concurrently will show that parental (emotion dysregulation, anxiety and depression, and rearing styles) and adolescent (emotion dysregulation, anxiety, and depression) factors are associated with school refusal behaviors. One hundred and six adolescents aged 12 to 18 years and their parents completed an online questionnaire measuring both parental and adolescent emotion dysregulation, anxiety, depression, parental rearing styles, and adolescents' school refusal behaviors. Adolescents with school refusal behaviors reported greater anxiety and depression, with their parents showing greater emotion dysregulation. Multivariate analyses showed that parental emotion dysregulation and adolescent age were associated with school refusal behaviors independently. Future management for school refusal behaviors should consider age-tailored approaches by incorporating training for parental emotion regulation skills.

Brain mechanisms of rumination and negative self-referential processing in adolescent depression

BackgroundDepression is linked to cognitive biases towards more negative and less positive self-relevant information. Rumination, perseverative negative thinking about the past and the self, may contribute to these biases. Methods159 adolescents (12–18 years), with a range of depression symptoms, completed the SRET during fMRI. Multiple regressions tested associations between conventional self-report and ecological momentary assessment (EMA) measured rumination, and neural and behavioral responses during a self-referent encoding task (SRET). ResultsHigher rumination (conventional self-report and EMA) was associated with more negative and fewer positive words endorsed and recalled. Higher self-reported (but not EMA) rumination was associated with higher accuracy in recognizing negative words and greater insula and dorsal anterior cingulate activity to negative versus positive words. LimitationsThe sample included mostly non-Hispanic White participants with household incomes above the national average, highlighting the need for replication in more diverse samples. Word endorsement discrepancies required fMRI analyses to model neural response to viewing negative versus positive words. ConclusionsAdolescents with higher rumination endorsed and recalled more negative and fewer positive words and recognized more negative words during the SRET. Higher insula reactivity, a key region for modulating externally-oriented attention and internally-oriented self-referential processes, may contribute to links between rumination and negative memory biases. These findings provide insight into neurocognitive mechanisms underlying depression.

Evaluating Adolescent Patient Outcomes and Staff Member Injuries at a General Psychiatric Inpatient Unit.

Short-term pediatric psychiatric hospitalization is used to manage acute-crisis behaviors. Few studies have detailed their clinical model and key metrics such as patient behavioral health outcomes and staff experience. This study describes a model which emphasizes group therapy based on dialectical behavior therapy during brief inpatient stays (average length of stay of 8 days). The study variables assessed included patient symptoms of depression, anxiety, and anger at discharge, patient satisfaction, and staff safety. The program produced significant improvements in adolescent depression, anxiety, and anger, and patients reported high satisfaction with the services received. However, there was a high rate of staff injuries, correlated with staffing ratios and the time of day. The key findings from this study demonstrate the effectiveness of brief inpatient programs and highlight variables that may impact staff experiences on these units, which could serve as further discussion points to improve clinical care.

The mediating role of family functioning between childhood trauma and depression severity in major depressive disorder and bipolar disorder

BackgroundChildhood trauma (CT) and family functioning exert significant influences on the course and long-term outcome of major depressive disorder (MDD) and bipolar disorder (BD) patients. Hence, we examined the intricate relationship between CT, family function, and the severity of depressive episodes in MDD and BD patients. Methods562 patients with depressive episodes (336 MDD and 226 BD) and 204 healthy controls (HCs) were included in this retrospective study. The 17-item Hamilton Depression Rating Scale (HAMD-17), Childhood Trauma Questionnaire (CTQ), and Family Adaptability and Cohesion Evaluation Scale (FACES II-CV) were assessed. Pearson correlation analysis and mediation analysis were performed. ResultsCT had both a direct and indirect impact on depression severity in MDD and BD groups. In MDD, family adaptability mediated the impact of all CT subtypes on depression severity (Effect = 0.113, [0.030, 0.208]). In BD, family cohesion played a mediating role between emotional neglect (EN) and HAMD-17 scores (Effect = 0.169, [0.008, 0.344]). Notable differences were observed in onset age, illness duration, episode frequency, family history, and CT subtypes between MDD and BD (P < 0.05). LimitationsThis study has several limitations including recall bias, lack of objective family functioning measures, small sample size, and cross-sectional design. ConclusionsFamily functioning mediated the impact of CT on depressive symptoms severity in MDD and BD patients. MDD patients with a history of CT exhibited reduced family adaptability, while BD patients with a history of EN had weaker familial emotional bonds. Our findings highlighted the importance of family-focused preventive interventions in mitigating the long-term effects of CT.

Is anxiety and depression transmissible? Depressed mother rats transmit anxiety- and depression-like phenotypes to cohabited rat pups through gut microbiota assimilation

ObjectiveThis study is to investigate the role of gut microbiota transmission in the development of anxiety/depression in offspring exposed to maternal depression. MethodOffspring rats were cohabitated with their depressed mother or father rats (which exposed to chronic unpredictable mild stress (CUMS)) for 2, 4, and 6 months, the anxiety- and depression-like behaviors, and interaction/caring activities between mother/father and their pups were detected. The gut microbiota composition and its relationship with behaviors were analyzed. Fecal microbiota transplantation (FMT) was performed to establish the gut microbiota of depressed/normal mother rats in the offspring rats to further confirm the role of “depressive gut microbiota” transmission in mediating the anxiety/depression in the pups. ResultsAnxiety and depression phenotypes can be transmitted from depressed mother rats to their cohabited offspring. Frequent interactions and gut microbiota assimilation were observed between rat mothers and their pups. Remodeling of the gut microbiota in pups by FMT could induce or attenuate anxiety- and depression-like phenotypes depending on the origin of the fecal microbiota. By comparison, the pups cohabiting with depressed father rats exhibited milder anxiety and depression. ConclusionsThese data together support that depressed mothers can transmit anxiety/depression to their pups through gut microbiota assimilation, which is related to frequent interactions. Our study reinforces the significance of mental health of mothers in preventing the occurrence of childhood anxiety and depression, and pointing out the possibility of remodeling intestinal microbiota as an effective therapeutic approach for treating anxiety/depression in children.

The protective effect of S-adenosylmethionine on chronic adolescent stress-induced depression-like behaviors by regulating gut microbiota

The efficacy and tolerability of current antidepressants for adolescent depression are inadequate. S-adenosylmethionine (SAMe), known for its effectiveness and minimal side effects in adult depression, remains unstudied in adolescents. This study explored the potential of SAMe to address depression-like behaviors in juvenile rats induced by chronic unpredictable mild stress (CUMS), with a focus on gut microbiome interactions. Adolescent male Wistar rats were subjected to a 4-week CUMS regimen and received daily intraperitoneal injections of 300 mg/kg SAMe. Behavioral assessments included the sucrose preference test, elevated plus maze test, open field test, and Y-maze test. Histopathological changes of the hippocampus and colon were observed by Nissl staining and hematoxylin and eosin staining, respectively. Gut microbiome composition was analyzed using Accurate 16S absolute quantification sequencing. The results showed that SAMe significantly improved behavioral outcomes, reduced histopathological damages in hippocampal neurons and colon tissues, and modulated the gut microbiota of depressed rats. It favorably altered the ratio of Bacteroidetes to Firmicutes, decreased the absolute abundance of Deferribacteres, and adjusted levels of key microbial genera associated with depression-like behaviors. These results suggested that SAMe could effectively counter depression-like behaviors in CUMS-exposed adolescent rats by mitigating hippocampal neuronal and colon damage and modulating the gut microbiota. This supports SAMe as a viable and tolerable treatment option for adolescent depression, highlighting the importance of the gut-brain axis in therapeutic strategies.

The path of depression in rural children: A fuzzy-set qualitative comparative analysis across multiple provinces in China

ObjectivesThis study explores the combinations of conditional variables contributing to depressive symptoms in rural children. MethodsWe analyzed data from 715 children from a rural mental health database, conducting detailed follow-up investigations on 129 children in Zhejiang and Henan provinces. We used fuzzy set Qualitative Comparative Analysis (fsQCA) and regression analysis to identify causal pathways leading to depression. ResultsThe results indicate that depression in rural children does not stem from a single, necessary condition but arises from multiple factors. Our findings highlight significant contributions from both maternal and paternal involvement. Specifically, maternal involvement, combined synergistically with peer support and problematic behaviors, as well as paternal involvement, together with peer support and anxiety, significantly affects depressive outcomes. Additionally, anxiety and strong peer relationships independently have a substantial impact on these outcomes. Effective mitigation strategies involve active parental engagement and robust peer support, reducing the influence of risk factors such as problematic behaviors and anxiety. LimitationsThe generalizability of the results is limited by cultural and geographical variations. The study also does not account for all potential factors influencing depression in rural children. ConclusionDepression in rural children results from multiple interacting factors. Tailored interventions addressing these specific combinations are recommended.

Altered dynamic functional connectivity of nucleus accumbens subregions in major depressive disorder: the interactive effect of childhood trauma and diagnosis.

Major depressive disorder (MDD) with childhood trauma represents a heterogeneous clinical subtype of depression. Previous research has observed alterations in the reward circuitry centered around the nucleus accumbens (NAc) in MDD patients. However, limited investigations have focused on aberrant functional connectivity (FC) within NAc subregions among MDD with childhood trauma. Thus, this study adopts analyses of both static FC (sFC) and dynamic FC (dFC) to examine neurobiological changes in MDD with childhood trauma. The bilateral nucleus accumbens shell (NAc-shell) and nucleus accumbens core (NAc-core) were selected as the seeds. Four participant groups were included: MDD with childhood trauma (n = 48), MDD without childhood trauma (n = 30), healthy controls (HCs) with childhood trauma (n = 57), and HCs without childhood trauma (n = 46). Our findings revealed both abnormal sFC and dFC between NAc-shell and NAc-core and regions including the middle occipital gyrus (MOG), anterior cingulate cortex, and inferior frontal gyrus in MDD with childhood trauma. Furthermore, a significant correlation was identified between the dFC of the left NAc-shell and the right MOG in relation to childhood trauma. Additionally, abnormal dFC moderated the link between childhood abuse and depression severity. These outcomes shed light on the neurobiological underpinnings of MDD with childhood trauma.

Self-compassion, self-referential caudate circuitry, and adolescent suicide ideation

Suicide is the second leading cause of death in youth, and depression is a strong proximal predictor of adolescent suicide. It is important to identify psychological factors that may protect against suicide ideation in depressed adolescents. Self-compassion may be such a factor. Converging evidence indicates the inverse association between self-compassion and suicide ideation, but the neural mechanisms underlying their link remain unknown. Because self-referential caudate activity is associated with both self-compassion and suicide ideation, its functional connectivity might explain their relationship. In this study, we examined the relationship between self-compassion and caudate functional connectivity during self-appraisals, a typical self-referential paradigm, and their associations with suicide ideation in both depressed and healthy youth. In the scanner, 79 depressed youth and 36 healthy controls evaluated, from various perspectives, whether phrases they heard were self-descriptive. Self-compassion and suicide ideation were rated with self-report and interview-based measures. We found that self-compassion was associated with stronger left caudate functional connectivity with bilateral posterior superior temporal sulcus/temporoparietal junction, the left middle temporal gyrus (MTG), and the left middle occipital gyrus during positive versus negative self-appraisals. Stronger left caudate connectivity with the left MTG explained the association between higher self-compassion and lower suicide ideation, even controlling for non-suicide ideation depression severity, anxiety severity, and non-suicidal self-injurious behavior. The findings suggest that the left caudate to MTG connectivity during positive versus negative self-referential processing could be a biomarker to be targeted by neural stimulation interventions for reducing suicide ideation in depressed youth, combined with self-compassion interventions.

Suicide risk among young people who use drugs in Hanoi, Vietnam: Prevalence and related factors.

Adolescents and young adults are vulnerable to suicidality, especially those at high risk such as young people who use drugs (YPUD). This study aimed to assess the prevalence and related factors of suicide risk among this population. We conducted a descriptive, cross-sectional study on YPUD aged 16-24 in the community in Hanoi, Vietnam. Data on socio-demographic characteristics, drug use, and adverse childhood experiences were collected using face-to-face questionnaires by research assistants. YPUD were screened by psychiatrists for depression, psychotic symptoms, and suicide risk, using the MINI questionnaire. Three hundred-seven YPUD (250 males, 57 females) participated in the study; of those, 86 (28.0%) were at risk of suicide. Gender (female), adverse childhood experiences, depression, and psychosis were relevant factors. The prevalence of suicide risk among young people using drugs was high. Therefore, suicide risk should be screened and monitored in the clinical assessment of this population. In addition, the intervention efforts to detect and intervene in adverse events during childhood may be one way to prevent mental health and suicide in later life.

Common and differential variables of anxiety and depression in adolescence: a nation-wide smartphone-based survey

BackgroundMental health in adolescence is critical in its own right and a predictor of later symptoms of anxiety and depression. To address these mental health challenges, it is crucial to understand the variables linked to anxiety and depression in adolescence.MethodsHere, we analyzed data of 278 adolescents that were collected in a nation-wide survey provided via a smartphone-based application during the COVID-19 pandemic. We used an elastic net regression machine-learning approach to classify individuals with clinically relevant self-reported symptoms of depression or anxiety. We then identified the most important variables with a combination of permutation feature importance calculation and sequential logistic regressions.Results40.30% of participants reported clinically relevant anxiety symptoms, and 37.69% reported depressive symptoms. Both machine-learning models performed well in classifying participants with depressive (AUROC = 0.77) or anxiety (AUROC = 0.83) symptoms and were significantly better than the no-information rate. Feature importance analyses revealed that anxiety and depression in adolescence are commonly related to sleep disturbances (anxiety OR = 2.12, depression OR = 1.80). Differentiating between symptoms, self-reported depression increased with decreasing life satisfaction (OR = 0.43), whereas self-reported anxiety was related to worries about the health of family and friends (OR = 1.98) as well as impulsivity (OR = 2.01).ConclusionOur results show that app-based self-reports provide information that can classify symptoms of anxiety and depression in adolescence and thus offer new insights into symptom patterns related to adolescent mental health issues. These findings underscore the potentials of health apps in reaching large cohorts of adolescence and optimize diagnostic and treatment.

Chronic stress and lack of social support: Role in adolescent depression and suicide-related behaviors in the context of the COVID-19 pandemic

ObjectiveThis study aimed to examine acute and chronic stressors, and perceived lack social support, and their associations with depression and suicidal ideation in adolescents during the COVID-19 pandemic. MethodsDeidentified data from (N = 270,153) U.S. adolescents aged 11 to 17 who completed the Patient Health Questionnaire 9-item tool (PHQ-9) in the years 2020 and 2021 were sourced from a collection of online screening tools that are free, confidential, anonymous, and scientifically validated. In addition to depression, the survey included questions about suicidality, past/chronic stressful events, and contributors to mental health problems and sociodemographic variables. SPSS software version 28 for descriptive analyses, and Mplus version 7.31 for confirmatory factor analysis (CFA) and structural equation modeling (SEM), were respectively used. ResultsParticipants were predominantly female, White, and heterosexual, and exhibited a high prevalence of severe depression and a significant frequency of suicidal thoughts. Significant associations were found between past/chronic stressful events, and lack of social support, with suicidality and depression. Mental health stress due to the COVID-19 pandemic itself presented no significant associations with depression and suicidality and was weakly and negatively associated with lack of social support and past/chronic stressors. DiscussionThese findings reinforce the notion that prior traumatic events can create vulnerabilities in the face of acute stressors, while social support can enhance resilience in adolescents. Factors that increase resilience, such as preventing traumatic events, reducing social stressors, and increasing social support, can serve as valuable guidelines for clinical and public health interventions.

Association Between Parental Problematic Internet Use and Adolescent Depression.

We examined the association between parental problematic internet use (PIU) and adolescent depression and whether this association varied based on internet-related rules. We recruited adolescents ages 13-18 and their parent using national Qualtrics panels (N = 4592 dyads). Measures included the Problematic and Risky Internet Use Screening Scale (PRIUSS-3), the Patient Health Questionnaire (PHQ-9), and the internet specific parenting practice scale (ISPPS). Parental PIU was associated with symptoms of adolescent depression, including suicidal ideation, even when controlling for adolescent PIU (β = 0.35, 95% CI [0.32, 0.38]). Time-related rules moderated this association in a non-linear way where the association was strongest when time-related rules were unclear / mid-range. The moderation effect was linear for content-related rules, where stricter rules were associated with a weaker association between parent PIU and adolescent depression. Results support clinicians assessing parent PIU when treating depressed adolescents and engaging parents in monitoring their adolescents' internet use content.

Closing the gap in access to child mental health care: provider feedback from the Wisconsin Child Psychiatry Consultation Program

BackgroundMental illnesses are common among children and negatively impact wellbeing during childhood as well as later in life. However, many children with these conditions are not able to access needed mental health care. The Wisconsin Child Psychiatry Consultation Program (WI CPCP) was created to reduce gaps in access to care by providing primary care providers with referral resources, access to behavioral health consultations, and training on mental health topics.ObjectivesThe purpose of this study was 1) to assess the effectiveness of the WI CPCP in Milwaukee County, providing specific insights into provider’s ability to care for child mental health, and 2) identify challenges Milwaukee PCPs faced in providing mental health care to child patients and contextualize these challenges in a conceptual framework of access to health care.MethodsA cross-sectional mixed-methods secondary data analysis was conducted using data collected from online baseline and nine-month follow-up surveys completed by providers participating in the program practicing in Milwaukee County from 2014 to 2022. Provider confidence and skill in providing mental health care was analyzed quantitatively using Two-sample Wilcoxon rank-sum (Mann–Whitney) tests (baseline vs. follow-up survey responses) and descriptive statistics (follow-up survey only). Provider challenges to providing mental health care were analyzed qualitatively using a thematic analysis research approach.ResultsResults from quantitative analyses showed that provider confidence and skill in treating childhood anxiety and depression improved from baseline to follow-up. Results from qualitative analyses were categorized by factors within and beyond the scope of WI CPCP. Within the scope of WI CPCP, providers reported a lack of knowledge of referral options and a lack of training in mental health care as well as a lack of knowledge in assessing and treating mental disorders. Still, many barriers to mental healthcare access persist that are beyond the scope of WI CPCP, such as long wait times and a lack of insurance coverage.ConclusionsThis study supports the effectiveness of the program to improve access to care for children. However, there is a need for additional solutions such as better reimbursement for mental health professionals and expanded insurance coverage.

Exploring the mediating role of the ventral attention network and somatosensory motor network in the association between childhood trauma and depressive symptoms in major depressive disorders

BackgroundChildhood trauma is closely tied to adult depression, but the neurobiological mechanisms remain unclear. Previous studies suggested associations between depression and large-scale brain networks such as the Ventral Attention Network (VAN) and Somatosensory Motor Network (SMN). This study hypothesized that functional connectivity (FC) within and between these networks mediates the link between childhood trauma and adult depression. MethodsThe Childhood Trauma Questionnaire (CTQ) assessed developmental experiences, and the Hamilton Rating Scale for Depression (HAMD-17) gauged depressive symptoms. Resting-state functional magnetic resonance imaging (fMRI) analyzed FC within and between the VAN and SMN. ResultsDepression group exhibited significantly higher HAMD and CTQ scores, as well as elevated FC within the VAN and between the VAN and SMN (P < 0.05). Positive correlations were found between HAMD total score and FC within the VAN (P < 0.05, r = 0.35) and between the VAN and SMN (P < 0.05, r = 0.34), as well as with CTQ total score (P < 0.05, r = 0.27). Positive correlations were also observed between CTQ total score and FC within the VAN (P < 0.05, r = 0.31) and between the VAN and SMN (P < 0.05, r = 0.29). In the mediation model, FC within and between the VAN and SMN significantly mediated childhood trauma and depression. LimitationsThe cross-sectional design limits causal inference. The sample size for different trauma types is relatively small, urging caution in generalizing findings. ConclusionsThe study underscores the association between depression severity, VAN dysfunction, abnormal VAN-SMN FC, and childhood trauma. These findings contribute to understanding the neurobiological mechanisms underlying childhood trauma and depression.

A study of somatization symptoms and low-frequency amplitude fluctuations of emotional memory in adolescent depression

Studies have revealed that somatization symptoms are associated with emotional memory in adolescents with depressive disorders. This study investigated somatization symptoms and emotional memory among adolescents with depressive disorders using low-frequency amplitude fluctuations (ALFF). Participants were categorized into the somatization symptoms (FSS) group, non-FSS group and healthy control group (HC). The correctness of negative picture re-recognition was higher in the FFS and HC group than in the non-FSS group. The right superior occipital gyrus and right inferior temporal gyrus were significantly larger in the FSS group than those in the non-FSS and HC groups. Additionally, the ALFF in the superior occipital and inferior temporal gyrus were positively correlated with CSI score. Furthermore, the ALFF values in the temporal region positively correlated with correct negative image re-recognition. The negative image re-recognition rate was positively correlated with the ALFF in the left and right middle occipital gyri. These findings indicated that somatization symptoms in adolescent depression are associated with the superior occipital gyrus and inferior temporal gyrus. Notably, somatization symptoms play a role in memory bias within depressive disorders, with middle occipital and inferior temporal gyri potentially serving as significant brain regions.

Ventral striatal-cingulate resting-state functional connectivity in healthy adolescents relates to later depression symptoms in adulthood

BackgroundDepression is a significant public health concern. Identifying biopsychosocial risk factors for depression is important for developing targeted prevention. Studies have demonstrated that blunted striatal activation during reward processing is a risk factor for depression; however, few have prospectively examined whether adolescent reward-related resting-state functional connectivity (rsFC) predicts depression symptoms in adulthood and how this relates to known risk factors (e.g., childhood trauma). MethodsAt baseline, 66 adolescents (mean age = 14.7, SD = 1.4, 68 % female) underwent rsFC magnetic resonance imaging and completed the Children's Depression Inventory (CDI). At follow-up (mean time between adolescent scan and adult follow-up = 10.1 years, SD = 1.6, mean adult age = 24.8 years, SD = 1.7), participants completed the Childhood Trauma Questionnaire (CTQ) and Beck Depression Inventory– Second Edition (BDI-2). Average rsFC was calculated between nodes in mesocorticolimbic reward circuitry: ventral striatum (VS), rostral anterior cingulate cortex (rACC), medial orbitofrontal cortex, and ventral tegmental area. Linear regressions assessed associations between rsFC, BDI-2, and CTQ, controlling for adolescent CDI, sex assigned at birth, and scan age (Bonferroni corrected). ResultsGreater childhood trauma was associated with higher adulthood depression symptoms. Stronger VS-rACC rsFC during adolescence was associated with greater depression symptoms in adulthood and greater childhood trauma. LimitationsThe small sample size, limited depression severity, and seed-based approach are limitations. ConclusionsThe associations between adolescent striatal-cingulate rsFC and childhood trauma and adult depression symptoms suggest this connectivity may be an early neurobiological risk factor for depression and that early life experience plays an important role. Increased VS-rACC connectivity may represent an over-regulatory response on the striatum, commonly reported in depression, and warrants further investigation.

Associations between prenatal stress with offspring inflammation, depression and anxiety

PurposeFew longitudinal studies have investigated the mediating role of inflammation during childhood in associations between prenatal maternal stress and adolescent mental health. The objective of this study was to examine the associations between prenatal maternal stress, concentrations of immune markers at age 9, and symptoms of generalized anxiety disorder (GAD) and depression during adolescence. MethodsThis study included 3723 mother-child pairs from the Avon Longitudinal Study of Parents and Children (ALSPAC). Prenatal maternal stress was examined using 55 items measured during pregnancy. Inflammation was assessed using serum concentrations of interleukin-6 (IL-6) and C-reactive protein (CRP) when children were 9 years old. GAD and depression were assessed when children were 16 and 18 years of age, respectively. Analyses comprised of structural equation models. ResultsPrenatal maternal stress was associated with higher concentrations of IL-6 in childhood, and with greater symptoms of depression and GAD in adolescence. However, we did not observe associations between prenatal maternal stress and CRP; also, CRP and IL-6 were not associated with depression and GAD. There was no evidence that CRP and IL-6 mediated the associations between prenatal maternal stress and either GAD or depression. ConclusionsPrenatal maternal stress is associated with IL-6 levels in childhood, and with GAD and depression during adolescence. Future studies should examine immune activity at multiple points during development in relation to mental health into adulthood to determine whether inflammation at different points during development could increase risk for mental health problems among children whose mothers experienced significant stressors during pregnancy.

Psico Bot: a robot for psychological assessment of children and adolescents

Chatbots can use fast, and sometimes specialized interactions in different situations, making them an option in the choice of tools to collect information. In the psychological assessment of children and adolescents, they can act as complementary sources, and help to describe, qualify and measure psychological and behavioral characteristics, in its various forms of expression, in different contexts. This study aimed to present Psico Bot, a chatbot developed to assess symptoms of anxiety and depression in children and adolescents. Consisting of 20 questions that map physical and psychological symptoms of the selected constructs, it was developed through the natural language Dialogflow for use in the Google Assistant conversation platform. The design of Psico Bot is based on a neutral representation, with no determined gender or age, facilitating quick identification by the user. Based on the use of multimethod evaluations, the Psico Bot can offer relevant information about the mental health of children and adolescents using language and devices that are easy to understand and handle by this population. For the evaluator, the tool offers quick response and specific information about each construct, enabling more effective interventions in elements of greatest need.
