Digital Phenotypes for Early Detection of Internet Gaming Disorder in Adolescent Students: Explorative Data-Driven Study

BACKGROUND

Limited awareness, social stigma, and access to mental health professionals hinder early detection and intervention of internet gaming disorder (IGD), which has emerged as a significant concern among young individuals. Prevalence estimates vary between 0.7% and 15.6%, and its recognition in the International Classification of Diseases, 11th Revision and Diagnostic and Statistical Manual of Mental Disorders, 5th Edition underscores its impact on academic functioning, social isolation, and mental health challenges.

OBJECTIVE

This study aimed to uncover digital phenotypes for the early detection of IGD among adolescents in learning settings. By leveraging sensor data collected from student tablets, the overarching objective is to incorporate these digital indicators into daily school activities to establish these markers as a mental health screening tool, facilitating the early identification and intervention for IGD cases.

METHODS

A total of 168 voluntary participants were engaged, consisting of 85 students with IGD and 83 students without IGD. There were 53% (89/168) female and 47% (79/168) male individuals, all within the age range of 13-14 years. The individual students learned their Korean literature and mathematics lessons on their personal tablets, with sensor data being automatically collected. Multiple regression with bootstrapping and multivariate ANOVA were used, prioritizing interpretability over predictability, for cross-validation purposes.

RESULTS

A negative correlation between IGD Scale (IGDS) scores and learning outcomes emerged (r166=-0.15; P=.047), suggesting that higher IGDS scores were associated with lower learning outcomes. Multiple regression identified 5 key indicators linked to IGD, explaining 23% of the IGDS score variance: stroke acceleration (β=.33; P<.001), time interval between keys (β=-0.26; P=.01), word spacing (β=-0.25; P<.001), deletion (β=-0.24; P<.001), and horizontal length of strokes (β=-0.21; P=.02). Multivariate ANOVA cross-validated these findings, revealing significant differences in digital phenotypes between potential IGD and non-IGD groups. The average effect size, measured by Cohen d, across the indicators was 0.40, indicating a moderate effect. Notable distinctions included faster stroke acceleration (Cohen d=0.68; P=<.001), reduced word spacing (Cohen d=.57; P=<.001), decreased deletion behavior (Cohen d=0.33; P=.04), and longer horizontal strokes (Cohen d=0.34; P=.03) in students with potential IGD compared to their counterparts without IGD.

CONCLUSIONS

The aggregated findings show a negative correlation between IGD and learning performance, highlighting the effectiveness of digital markers in detecting IGD. This underscores the importance of digital phenotyping in advancing mental health care within educational settings. As schools adopt a 1-device-per-student framework, digital phenotyping emerges as a promising early detection method for IGD. This shift could transform clinical approaches from reactive to proactive measures.

Virtual Schooling and Pediatric Mental Health During the COVID-19 Pandemic

In this single-site, retrospective, descriptive chart review and survey, we investigated changes in pediatric behavioral health needs during the COVID-19 pandemic and the relationship between virtual schooling and hospitalized children's mental health. Subjects included patients aged 6 and 18 years during the 2015 to 2019 and 2020 to 2021 school years who received inpatient mental health care. Parents of patients admitted in 2020 to 2021 were surveyed regarding their child's schooling. We additionally described and compared subjects using descriptive data, including proxies for illness severity, and assessed how these outcomes changed during the pandemic and correlated with school modality. During the pandemic, the distribution of diagnoses changed, and some markers of severity increased. Patients in exclusively virtual school had higher rates of mood and anxiety disorders and tic disorders, and lower rates of eating and disruptive behavior disorders, than patients with recent in-person school. Further study is needed regarding the impact of virtual schooling on pediatric mental health.

Tics of Trauma: Unique Case of Trauma-Associated Psychogenic Tics in an Adolescent Patient

Tic disorders are a common psychiatric diagnosis in adolescents. While often a primary disorder, there have been few reports of trauma-associated secondary psychogenic tics. In this case, we detail a 16-year-old girl with a history of trauma who initially presented with depression and trauma-related anxiety. During the course of treatment, she also developed verbal and motor tic-like symptoms that worsened with stress and court proceedings. We classify these new symptoms as psychogenic tics secondary to the trauma associated with sexual abuse. We explore the implication of psychiatric comorbidities, socio-legal stressors, and medication changes in the patient’s new-onset motor and vocal tics. This case points toward a need for consideration of this unique psychiatric manifestation of trauma-associated tics in adolescents with a history of sexual abuse and with otherwise normal neurological and physical examinations.

Energy Drink Use in Adolescents With and Without ADHD: Trends and Influences

OBJECTIVE

We sought to determine the frequency, reasons for, and factors associated with energy drink consumption in adolescents with or without attention deficit hyperactivity disorder (ADHD).

DESIGN

Anonymous surveys were completed by 115 adolescents and their parents prior to appointments at two separate outpatient clinics (pediatric and psychiatric) over a three-month period. Trained staff provided surveys to be completed by adolescents and their parents on a voluntary basis, and all data was self-reported. Care was given to ensure adolescents and their parents completed surveys independently from each other.

RESULTS

A total of 114 adolescent surveys and 100 parent surveys were included in analysis. There was a statistically significant association between parent and adolescent consumption of energy drinks. The mean number of energy drinks consumed in the past month was lower among adolescents than among parents. The most common reason among all respondents for energy drink consumption was to promote wakefulness.

CONCLUSION

This survey found that adolescents with parents who consumed energy drinks were more likely to drink energy drinks themselves. Trends indicate that consumption of energy drinks is increasing in the adolescent population, with potential for serious adverse events resulting from high caffeine content, warranting the need for public health awareness.

Can the Child Behavior Checklist (CBCL) help characterize the types of psychopathologic conditions driving child psychiatry referrals?

Background:

Little is known about the scope of problems driving referrals to child and adolescent psychiatry services. Identifying the full range of mental disorders affecting a particular child can help triage the child to a clinician with the appropriate level of expertise. The Child Behavior Checklist (CBCL) is an easy-to-use assessment tool that may provide invaluable information regarding the severity of the presenting complaints and also aid in the referral process.

Objective:

To assess the utility of the CBCL to gain insights into the type of clinical problems driving referrals of youth to an outpatient pediatric psychiatry clinic.

Method:

The sample consisted of 418 newly referred youth 4-18 years of age of both sexes. Parents completed the CBCL assessing psychopathology and competence. Rates of patients with elevated T-scores on each scale were calculated for the whole group and stratified by sex and age (≤12 versus >12).

Results:

The CBCL identified high rates of psychopathology affecting referred youth. It also provided information on the type of suspected disorders affecting a particular child as well as their severity, critical information to guide likely differing clinical needs and therapeutic approaches. It also helped identify a high number of youth affected with multiple psychopathological conditions, likely to require a high level of clinical attention. Overall, males were significantly more impaired than females but there were no major differences between children and adolescents.

Conclusions:

The CBCL can aid in the identification of individual and comorbid mental disorders affecting youth seeking mental health services by providing specific information about the presence and the severity of specific suspected disorder. These findings have implications for prioritizing scarce resources in child mental health and for improved consideration of the complexity of clinical presentations to pediatric psychiatry programs of any type.

Depressive and Anxiety Symptoms among Pediatric In-Patients with Dengue Fever: A Case-Control Study

BACKGROUND

Psychiatric symptoms have been reported in adult patients with dengue fever (DF); however, information on pediatric patients remains inadequate. We sought to identify the prevalence and predictors of depressive and anxiety symptoms and identify other psychiatric symptoms among pediatric patients with DF. This case-control study involved pediatric in-patients (n = 225) who had clinical or serologic-confirmed DF and healthy school-based controls (n = 260). Participants completed the Revised Child Anxiety and Depression Scale (RCADS).

RESULTS

The prevalence of depressive (13.3%) and anxiety (34.2%) symptoms among pediatric patients with DF was significantly (p < 0.001) higher than that among controls (3.5% and 16.2%, respectively). Multiple linear regression analysis found that age, family history of DF, ≤2 days of hospitalization, myalgia, and arthralgia were predictors of increased depressive and anxiety symptoms among the patients. Further, 26.7% of pediatric patients reported irritability, agitation, visual hallucinations, and aggressiveness.

CONCLUSION

Pediatric patients present depressive and anxiety symptoms whose levels were associated with social and clinical factors. However, whether these symptoms are present only during the infection or may still persist after recovery or are brought by children's adverse reactions to hospitalization are unknown, and thus, further studies are needed.

Factors Associated With Length of Stay in Emergency Departments for Pediatric Patients With Psychiatric Problems

OBJECTIVES

Length of stay (LOS) and boarding for pediatric psychiatric patients presenting in the emergency department (ED) have been understudied, despite evidence that children with psychiatric disorders experience longer LOS relative to those without. This investigation examined correlates of LOS and boarding among youth with psychiatric disorders presenting to the ED in a large, statewide database.

METHODS

Using the 2010 to 2013 Florida ED discharge database, generalized linear mixed models were used to examine for associations between LOS and patient and hospital characteristics among pediatric patients (<18 years) who presented with a primary psychiatric diagnosis (N = 44,328).

RESULTS

Patients had an overall mean ± SD ED LOS of 5.96 ± 8.64 hours. Depending on the definition used (ie, 12 or 6 hours), between 23% and 58% of transferred patients were boarded. Patient characteristics associated with a longer LOS included female sex, being 15 to 17 years old, Hispanic ethnicity, having Medicaid or VA/TriCare insurance, having impulse control problems, having mood or psychotic disorders, and exhibiting self-harm behaviors. Patient transfer, large hospital size, and rural designation were associated with longer LOS. Teaching hospital status and profit status were not significantly associated with LOS.

CONCLUSIONS

These data suggest that LOS for pediatric psychiatry patients in the ED varies significantly by psychiatric presentation, patient disposition, and hospital factors. Such findings have implications for quality of care, patient safety, and health outcomes.

Understanding the pediatric psychiatric phenotype of 22q11.2 deletion syndrome

The purpose of this article is to provide an overview of current insights into the neurodevelopmental and psychiatric manifestations of 22q11.2 deletion syndrome (22q11DS) in children and adolescents. The pediatric neuropsychiatric expression of 22q11DS is characterized by high variability, both interindividual and intraindividual (different expressions over the lifespan). Besides varying levels of intellectual disability, the prevalence of autism spectrum disorders, attention deficit disorders, anxiety disorders, and psychotic disorders in young individuals with 22q11DS is significantly higher than in the general population, or in individuals with idiopathic intellectual disability. Possible explanations for this observed phenotypic variability will be discussed, including genetic pleiotropy, gene-environment interactions, the age-dependency of phenotypes, but also the impact of assessment and ascertainment bias as well as the limitations of our current diagnostic classification system. The implications inferred by these observations aforementioned bear direct relevance to both scientists and clinicians. Observations regarding the neuropsychiatric manifestations in individuals with 22q11DS exemplify the need for a dimensional approach to neuropsychiatric assessment, in addition to our current categorical diagnostic classification system. The potential usefulness of 22q11DS as a genetic model to study the early phases of schizophrenia as well as the phenomenon of neuropsychiatric pleiotropy observed in many CNV's will be delineated. From a clinical perspective, the importance of regular neuropsychiatric evaluations with attention to symptoms not always captured in diagnostic categories and of maintaining equilibrium between individual difficulties and competencies and environmental demands will be discussed.

Association between peripheral manganese levels and attention-deficit/hyperactivity disorder: a preliminary meta-analysis

Evidence has suggested that dysregulation of the dopaminergic system may play a significant role in the pathogenesis of attention-deficit/hyperactivity disorder (ADHD) in children. Manganese, a neurotoxicant, has been reported to exert its neurotoxicity by affecting the dopaminergic system. However, the association between peripheral manganese levels and ADHD has not been comprehensively reviewed. This study aimed to investigate the association between peripheral manganese levels and ADHD in children. An electronic search was performed on databases including PubMed, ProQuest, ClinicalKey, Cochrane Library, ClinicalTrials.gov, Embase, Web of Science, and ScienceDirect with last search on March 25th, 2018. As per the inclusion criteria, human observational studies investigating peripheral manganese levels in children with ADHD and controls were included. The meta-analysis was performed using a random-effects model, and possible confounders were examined by subgroup analysis. In total, four articles with 175 ADHD children and 999 controls were recruited. The manganese levels were significantly higher in ADHD children than in controls (p=0.033), when studies investigating blood levels and those investigating hair levels were included. However, when only studies investigating blood levels were included, there was no significant difference between ADHD children and controls (p=0.076). Our results support higher peripheral manganese levels in children diagnosed with ADHD than those in controls. Further primary studies are needed to clarify this association.
