Investigation of bias in the automated assessment of school violence.

OBJECTIVES: Natural language processing and machine learning have the potential to lead to biased predictions. We designed a novel Automated RIsk Assessment (ARIA) machine learning algorithm that assesses risk of violence and aggression in adolescents using natural language processing of transcribed student interviews. This work evaluated the possible sources of bias in the study design and the algorithm, tested how much of a prediction was explained by demographic covariates, and investigated the misclassifications based on demographic variables. METHODS: We recruited students 10-18 years of age and enrolled in middle or high schools in Ohio, Kentucky, Indiana, and Tennessee. The reference standard outcome was determined by a forensic psychiatrist as either a "high" or "low" risk level. ARIA used L2-regularized logistic regression to predict a risk level for each student using contextual and semantic features. We conducted three analyses: a PROBAST analysis of risk in study design; analysis of demographic variables as covariates; and a prediction analysis. Covariates were included in the linear regression analyses and comprised of race, sex, ethnicity, household education, annual household income, age at the time of visit, and utilization of public assistance. RESULTS: We recruited 412 students from 204 schools. ARIA performed with an AUC of 0.92, sensitivity of 71%, NPV of 77%, and specificity of 95%. Of these, 387 students with complete demographic information were included in the analysis. Individual linear regressions resulted in a coefficient of determination less than 0.08 across all demographic variables. When using all demographic variables to predict ARIA's risk assessment score, the multiple linear regression model resulted in a coefficient of determination of 0.189. ARIA performed with a lower False Negative Rate (FNR) of 15.2% (CI [0 - 40]) for the Black subgroup and 12.7%, CI [0 - 41.4] for Other races, compared to an FNR of 26.1% (CI [14.1 - 41.8]) in the White subgroup. CONCLUSIONS: Bias assessment is needed to address shortcomings within machine learning. In our work, student race, ethnicity, sex, use of public assistance, and annual household income did not explain ARIA's risk assessment score of students. ARIA will continue to be evaluated regularly with increased subject recruitment.

Management of Emotion Dysregulation and Outbursts in Children and Adolescents.

PURPOSE OF REVIEW: Emotion dysregulation and outbursts are very common reasons for referral to child and adolescent mental health services and a frequent cause of admission to hospitals and residential programs. Symptoms of emotion dysregulation and outburst are transdiagnostic, associated with many disorders, have the potential to cause severe impairment and their management presents a major challenge in clinical practice. RECENT FINDINGS: There are an increasing number of psychosocial interventions that demonstrate promise in improving emotion dysregulation and outbursts. Acute care systems to manage the most severely ill patients have limited best practice guidelines but program advancements indicate opportunities to improve care models. Pharmacotherapy may be of assistance to psychosocial interventions but must be used with caution due to potential adverse effects. Much remains to be discovered however evidence informed, targeted treatments for specific populations show potential for future improvements in outcomes.

Psychiatric Education for Pediatric Emergency Medicine Fellows: Should We be Doing More?

The number of psychiatric encounters is steadily increasing across all pediatric emergency departments. Based on this growing national crisis, we hypothesized there is a lack of robust education in behavioral/mental health emergencies during pediatric emergency medicine (PEM) fellowship. METHODS: This was a cross-sectional survey of PEM fellowship directors. The survey was submitted to the Pediatric Emergency Medicine Program Director Survey Committee via REDCap to all 83 fellowship directors. RESULTS: Fifty-five (66%) PEM fellowship directors completed the survey from September 2019 to December 2019. Forty-three (78%) programs provide some type of didactic teaching, although only 7 (13%) programs offer more than 5 hours of didactics over 3 years of fellowship. Six (11%) programs offer electronic resources, 13 (24%) offer simulations in psychiatry, and only 4 (7%) programs require any type of psychiatry rotation. Forty-six (84%) programs do not currently use psychiatric emergencies as a competency for evaluating PEM fellows. Program directors felt significantly more confident in faculty than graduating fellows in the management of numerous diagnoses including agitation (P < 0.001), homicidal ideation (P = 0.044), neuroleptic malignant syndrome (P = 0.006), acute dystonia (P < 0.001), and heroin overdose (P = 0.022). Ninety-six percent felt online curricula would be helpful to address this knowledge gap. CONCLUSIONS: Despite growing behavioral/mental health needs in the pediatric emergency department, there continues to be opportunity to improve psychiatric education during PEM fellowship. Program directors felt more confident in faculty than graduating fellows with several psychiatric diagnoses. Pediatric emergency medicine fellowship directors expressed a strong interest in online tools to assist in the education of PEM fellows.

Systematic Review of Religiosity's Relationship with Suicidality, Suicide Related Stigma, and Formal Mental Health Service Utilization among Black Americans.

Rates of suicide have increased among Black Americans. Suicide is now the 3rd leading cause of death for Black Americans between the ages of 1-19 and the 4th leading cause of death for Black Americans aged 20-44. Due to the increasing need in the community, a marked increase in literature focusing on suicide in the Black community has been published since 2018. To build a better understanding of the current state of the literature on suicidality among Black Americans and to offer suggestions for further areas of research, a systematic review was conducted. Spirituality and religious beliefs are often an important cultural focus in the Black community. Some religious beliefs pose potential unintended regarding the sanctity of life among Black Americans. The focus of this systematic review was religiosity's effect on suicidality among Black Americans. Religiosity was found to have a protective effect against suicidality among Black Americans while discouraging formal mental health services utilization. This systematic review also reveals a dearth of research on the relationship between religiosity and suicide related stigma. Areas for further research are mentioned, and religious institutions as mental health intervention centers are encouraged.

A Large Naturalistic Study on the BRACHA: Confirmation of the Predictive Validity.

Aggression is a major challenge on child/adolescent inpatient psychiatric units. A screening instrument to accurately identify risk is urgently needed. To determine the predictive validity of the Brief Rating of Aggression by Children and Adolescents (BRACHA). Prospective cohort study. BRACHA is administered by clinical staff in the emergency department (ED) prior to inpatient psychiatric admission. A consecutive sample of 10,054 admitted patients from 2010-2021. No patients refused screening nor were excluded. BRACHA administered to patients in the ED prior to admission at Cincinnati Children's Hospital Medical Center (CCHMC). Patient behavioral outcomes measured by Overt Aggression Scale (OAS), categorizing aggression as verbal or physical, then as towards self, others, or objects. Female patients comprised 53.6% (n = 5,386) of the sample. Most patients were white (n = 6,556, 65.2%). Patients ranged in age from 4 to 18 years, with a mean age of 13.6 ± 3.1 years. A single biological parent (n = 5,317, 52.9%) was the predominant living arrangement among patients. The Area Under the Curve (AUC), as an assessment of predictive validity across all possible cut-offs of BRACHA scores ranged from 0.640 (aggression to self) to 0.758 (physical aggression towards others). Our findings support the BRACHA as a useful predictive instrument for aggression in inpatient psychiatric admissions from ED regardless of length of stay. Treating staff are then able to immediately classify risk level and inform care plans for all lengths of hospitalization. Applies to potential risk for aggression, except for self-aggression. Future data analyses will evaluate demographic factors to determine which improve predictive power of the BRACHA and can be used to create a BRACHA calculator. To our knowledge, this naturalistic outcomes study is one of the largest in psychiatry. The BRACHA will continue to be studied to evaluate risk for aggression on inpatient units and aim to assist in keeping unit staff and patients safe.

Individual prediction of symptomatic converters in youth offspring of bipolar parents using proton magnetic resonance spectroscopy.

Children of individuals with bipolar disorder (bipolar offspring) are at increased risk for developing mood disorders, but strategies to predict mood episodes are unavailable. In this study, we used support vector machine (SVM) to characterize the potential of proton magnetic resonance spectroscopy (1H-MRS) in predicting the first mood episode in youth bipolar offspring. From a longitudinal neuroimaging study, 19 at-risk youth who developed their first mood episode (converters), and 19 without mood episodes during follow-up (non-converters) were selected and matched for age, sex and follow-up time. Baseline 1H-MRS data were obtained from anterior cingulate cortex (ACC) and bilateral ventrolateral prefrontal cortex (VLPFC). Glutamate (Glu), myo-inositol (mI), choline (Cho), N-acetyl aspartate (NAA), and phosphocreatine plus creatine (PCr + Cr) levels were calculated. SVM with a linear kernel was adopted to classify converters and non-converters based on their baseline metabolites. SVM allowed the significant classification of converters and non-converters across all regions for Cho (accuracy = 76.0%), but not for other metabolites. Considering all metabolites within each region, SVM allowed the significant classification of converters and non-converters for left VLPFC (accuracy = 76.5%), but not for right VLPFC or ACC. The combined mI, PCr + Cr, and Cho from left VLPFC achieved the highest accuracy differentiating converters from non-converters (79.0%). Our findings from this exploratory study suggested that 1H-MRS levels of mI, Cho, and PCr + Cr from left VLPFC might be useful to predict the development of first mood episode in youth bipolar offspring using machine learning. Future studies that prospectively examine and validate these metabolites as predictors of mood episodes in high-risk individuals are necessary.

Lessons Learned to Building Stakeholder Engagement during the Initial Stages of Pragmatic Research Development and Implementation.

Research does not occur in a vacuum. Effective stakeholder engagement occurs on several levels, including outside influence and cooperation inside the institution. Little guidance around designing and implementing pragmatic mental health research exists. The following paper outlines lessons learned during the initial stages of research design and implementation for a project focused on mental health treatment outcomes.

Adherence with an Acute Agitation Algorithm and Subsequent Restraint Use.

Timely use of pharmacological interventions to treat acute agitation has the potential to decrease physical restraint use. The aim of this study is to determine if adherence to standardized pharmacological recommendations for the treatment of acutely agitated pediatric patients decreases physical restraint use. Additionally, this study aims to identify predictors of physical restraint use and describe treatment related adverse events. This is a retrospective chart review of patient visits between September 1, 2016 and August 31, 2017. Patient visits were included if the patient presented to the pediatric emergency department, met ICD-10 codes, and received pharmacologic management or physical restraint to treat acute agitation. The differences in rate of physical restraint was assessed between patients treated according to the standardized pharmacological recommendations and patients who were not. 447 patients were included with a mean age of 13 years. No significant difference in physical restraint use was found when standardized pharmacological recommendations were followed compared to when they were not (P = 0.16). Only presentation on day shift when compared to evening shift resulted in increased odds of being restrained (OR 2.03; 95% CI 1.18, 3.50). Nine adverse events possibly related to medications were identified with none considered to be of significant clinical concern. Standardized pharmacological treatment recommendations was not associated with a decrease in physical restraint use for agitated patients presenting to the pediatric emergency department. The pharmacologic strategies utilized were generally safe and well tolerated in this patient population.

Automated Risk Assessment for School Violence: a Pilot Study.

School violence has increased over the past ten years. This study evaluated students using a more standard and sensitive method to help identify students who are at high risk for school violence. 103 participants were recruited through Cincinnati Children's Hospital Medical Center (CCHMC) from psychiatry outpatient clinics, the inpatient units, and the emergency department. Participants (ages 12-18) were active students in 74 traditional schools (i.e. non-online education). Collateral information was gathered from guardians before participants were evaluated. School risk evaluations were performed with each participant, and audio recordings from the evaluations were later transcribed and manually annotated. The BRACHA (School Version) and the School Safety Scale (SSS), both 14-item scales, were used. A template of open-ended questions was also used. This analysis included 103 participants who were recruited from 74 different schools. Of the 103 students evaluated, 55 were found to be moderate to high risk and 48 were found to be low risk based on the paper risk assessments including the BRACHA and SSS. Both the BRACHA and the SSS were highly correlated with risk of violence to others (Pearson correlations>0.82). There were significant differences in BRACHA and SSS total scores between low risk and high risk to others groups (p-values <0.001 under unpaired t-test). In particular, there were significant differences in individual SSS items between the two groups (p-value <0.001). Of these items, Previous Violent Behavior (Pearson Correlation = 0.80), Impulsivity (0.69), School Problems (0.64), and Negative Attitudes (0.61) were positively correlated with risk to others. The novel machine learning algorithm achieved an AUC of 91.02% when using the interview content to predict risk of school violence, and the AUC increased to 91.45% when demographic and socioeconomic data were added. Our study indicates that the BRACHA and SSS are clinically useful for assessing risk for school violence. The machine learning algorithm was highly accurate in assessing school violence risk.

Eye Gaze Patterns Associated with Aggressive Tendencies in Adolescence.

Social information processing theory hypothesizes that aggressive children pay more attention to cues of hostility and threat in others' behavior, consequently leading to over-interpretation of others' behavior as hostile. While there is abundant evidence of aggressive children demonstrating hostile attribution biases, less well documented is whether such biases stem from over-attendance and hypersensitivity to hostile cues in social situations. Over-attendance to hostile cues would be typified by deviations at any stage of the multi-stage process of social information processing models. While deviations at later stages in social information processing models are associated with aggressive behavior in children, the initial step of encoding has historically been difficult to empirically measure, being a low level automatic process unsuitable for self-report. We employed eye-tracking methodologies to better understand the visual encoding of such social information. Eye movements of ten 13-18 year-old children referred from clinical and non-clinical populations were recorded in real time while the children viewed scenarios varying between hostile, non-hostile and ambiguous social provocation. In addition, the children completed a brief measure of risk of aggression. Aggressive children did attend more to the social scenarios with hostile cues, in particular attending longest to those hostile scenarios where the actor in the scenario had a congruent emotional response. These findings corroborate social information processing theory and the traditional bottom-up processing hypotheses that aggressive behavior relates to increased attention to hostile cues.

The Generalized Anxiety Disorder 7-item scale in adolescents with generalized anxiety disorder: Signal detection and validation.

BACKGROUND: In pediatric patients with anxiety disorders, existing symptom inventories are either not freely available or require extensive time and effort to administer. We sought to evaluate a brief self-report scale-the Generalized Anxiety Disorder 7-item scale (GAD-7)-in adolescents with generalized anxiety disorder (GAD). METHODS: The Pediatric Anxiety Rating Scale (PARS) and the GAD-7 were administered to youth with GAD (confirmed by structured interview). Relationships between the measures were assessed, and sensitivity and specificity was determined with regard to a global symptom severity measure (Clinical Global Impression-Severity). RESULTS: In adolescents with GAD (N = 40; mean age, 14.8 ± 2.8), PARS and GAD-7 scores strongly correlated (R = 0.65, P ≤ .001) and a main effect for symptom severity was observed (P ≤ .001). GAD-7 scores ≥11 and ≥17 represented the optimum specificity and sensitivity for detecting moderate and severe anxiety, respectively. CONCLUSIONS: The PARS and GAD-7 similarly reflect symptom severity. The GAD-7 is associated with acceptable specificity and sensitivity for detecting clinically significant anxiety symptoms. GAD-7 scores may be used to assess anxiety symptoms and to differentiate between mild and moderate GAD in adolescents, and may be more efficient than the PARS.

Beyond DSM-5 and IQ Scores: Integrating the Four Pillars to Forensic Evaluations.

The current adult and child forensic psychiatrist is well trained, familiar, and comfortable with the use of the semi-structured Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, APA 2013 (DSM-5) [In APA, 2003] interview style. The author's assertion is not that this method is invalid or unreliable; rather, that it can be complemented by integrating elements of the defendant's four pillar assessment. Assessing the four pillars expands on the information provided by a semi-structured DSM-5-style interview in psychiatry. The four pillars are the foundation of a person's personality; temperament, cognition (learning abilities or weaknesses), cognitive flexibility (theory of mind) and internal working models of attachment, within the backdrop of the family and of the social and cultural environment in which they have lived. The importance of the study of four pillars is based on the understanding that human behavior and psychopathology as a complex and multifaceted process that includes the level of social-emotional maturity and cognitive abilities (In Delgado et al. Contemporary Psychodynamic Psychotherapy for Children and Adolescents: Integrating Intersubjectivity and Neuroscience. Springer, Berlin, 2015). The four pillars are not new concepts, rather they had been studied by separate non-clinical disciplines, and had not been integrated to the clinical practice. As far as we know, it wasn't until Delgado et al. (Contemporary Psychodynamic Psychotherapy for Children and Adolescents: Integrating Intersubjectivity and Neuroscience. Springer, Berlin, 2015) incorporated the four pillars in a user-friendly manner to clinical practice.

A Pilot Study on Developing a Standardized and Sensitive School Violence Risk Assessment with Manual Annotation.

School violence has increased over the past decade and innovative, sensitive, and standardized approaches to assess school violence risk are needed. In our current feasibility study, we initialized a standardized, sensitive, and rapid school violence risk approach with manual annotation. Manual annotation is the process of analyzing a student's transcribed interview to extract relevant information (e.g., key words) to school violence risk levels that are associated with students' behaviors, attitudes, feelings, use of technology (social media and video games), and other activities. In this feasibility study, we first implemented school violence risk assessments to evaluate risk levels by interviewing the student and parent separately at the school or the hospital to complete our novel school safety scales. We completed 25 risk assessments, resulting in 25 transcribed interviews of 12-18 year olds from 15 schools in Ohio and Kentucky. We then analyzed structured professional judgments, language, and patterns associated with school violence risk levels by using manual annotation and statistical methodology. To analyze the student interviews, we initiated the development of an annotation guideline to extract key information that is associated with students' behaviors, attitudes, feelings, use of technology and other activities. Statistical analysis was applied to associate the significant categories with students' risk levels to identify key factors which will help with developing action steps to reduce risk. In a future study, we plan to recruit more subjects in order to fully develop the manual annotation which will result in a more standardized and sensitive approach to school violence assessments.

Antidepressant tolerability in anxious and depressed youth at high risk for bipolar disorder: a prospective naturalistic treatment study.

OBJECTIVE: Depressive and anxiety disorders are common in youth who are at risk for bipolar disorder (i.e., youth who have at least one parent with bipolar disorder) and antidepressants are commonly prescribed as treatment. However, there are few data regarding the safety and tolerability of antidepressants in this population. Therefore, we sought to prospectively examine the effects of these medications in children and adolescents who are diagnosed with depressive or anxiety disorders and have a parent with bipolar I disorder. METHODS: Youth aged 9-20 years, with at least one parent with bipolar I disorder [high risk (HR)], were recruited (n = 118) and assessed using semi-structured diagnostic interviews. Participants were prospectively evaluated using a modified version of the Longitudinal Interval Follow-up Evaluation to assess changes in affective and anxiety symptoms and were treated naturalistically. RESULTS: Over the course of 43-227 weeks (mean duration of follow-up: 106 ± 55 weeks), 21% (n = 25) of youth had antidepressant exposure and, of these, 57% (n = 12) had an adverse reaction (e.g., irritability, aggression, impulsivity, or hyperactivity) that led to antidepressant discontinuation. Those patients who experienced an adverse reaction were significantly younger than those who did not (p = 0.02) and discontinuation of antidepressant therapy secondary to an adverse event occurred at an average of 16.7 ± 17.4 weeks (median: 11 weeks, range: 2-57 weeks). Cox proportional hazard analyses yielded a hazard ratio of 0.725 (p = 0.03), suggesting that there is a 27% decrease in the likelihood of an antidepressant-related adverse event leading to discontinuation with each one-year increase in age. CONCLUSIONS: Antidepressant medications may be poorly tolerated in youth with a familial risk for developing mania. Controlled studies further assessing treatments for depression and anxiety in HR youth are urgently needed.

Pediatric emotion dysregulation: biological and developmental evidence for a dimensional approach.

The following review article examines the value of a dimensional approach to research in relation to recent findings of child and adolescent emotion dysregulation. With the publication of the DSM-5, it is important to keep in mind that difficulties in pinpointing causal mechanisms may result from the collective grouping of different emotional deficits by diagnoses. Evidence available from studies examining pediatric emotion dysregulation indicate strengths in the dimensional approach for research, especially in light of developmental changes to neural activations of emotion regulation. Use of a dimensional approach in research appears to be an effective tactic that could pave the way for a better understanding of pediatric emotion dysregulation and thereby elucidate better treatments and outcomes for those with this behavioral deficit, regardless of diagnosis.

Pharmacology and pharmacogenetics of pediatric ADHD with associated aggression: a review.

Attention deficit hyperactivity disorder (ADHD) is often associated with symptoms of aggression in children and adolescents. Clinically, this is complex because aggression can be from hyperactivity and impulsivity, or could be a distinct symptom from a comorbid diagnosis. Past research has recommended first treating the primary disorder of ADHD. Stimulants are the most common treatment for pediatric ADHD, which can be helpful in decreasing aggressive behaviors. Alpha-adrenergic agonists and atomoxetine (ATX) are non-stimulant medications for ADHD and aggression, but more research is necessary to compare these drugs to stimulants. If aggressive symptoms do not improve from treating the primary disorder, aggression can be treated separately. Risperidone, lithium, valproic acid, clonidine, and guanfacine have shown positive results in reducing aggression, but studies including children with aggression and ADHD are limited. The variability in treatment tolerability in patients has stimulated research in pharmacogenetics for ADHD. Although this field is still emerging, research has found evidence supporting a link between the response rate of methylphenidate and the dopamine transporter (DAT1) and a link between the metabolism rate of atomoxetine and hepatic cytochrome 450 isozymes. Pharmacogenetics may be relevant to ADHD and associated aggression. Further research in pharmacogenetics will strive to identify patterns of genetic variations that can tailor individual treatments.

The association between salivary hormone levels and children's inpatient aggression: a pilot study.

Aggression is a common management problem for child psychiatry hospital units. We describe an exploratory study with the primary objective of establishing the feasibility of linking salivary concentrations of three hormones (testosterone, dehydroepiandrosterone [DHEA], and cortisol) with aggression. Between May 2011 and November 2011, we recruited 17 psychiatrically hospitalized boys (age 7-9 years). We administered the Brief Rating of Aggression by Children and Adolescents (BRACHA) and Predatory-Affective Aggression Scale (PAAS) upon admission. Saliva samples were collected from the participants during a 24-h period shortly after admission: immediately upon awakening, 30 min later, and again between 3:45 and 7:45 P.M. Nursing staff recorded Overt Aggression Scale ratings twice a day during hospitalization to quantify aggressive behavior. The salivary cortisol concentrations obtained from aggressive boys 30 min after awakening trended higher than levels from the non-aggressive boys (p = 0.06), were correlated with the number of aggressive incidents (p = 0.04), and trended toward correlation with BRACHA scores (p = 0.06). The aggressive boys also showed greater morning-to-evening declines in cortisol levels (p = 0.05). Awakening levels of DHEA and testosterone were correlated with the severity of the nearest aggressive incident (p < 0.05 for both). The BRACHA scores of the aggressive boys were significantly higher than scores of the non-aggressive boys (p < 0.001). Our data demonstrate the feasibility of collecting saliva from children on an inpatient psychiatric unit, affirm the utility of the BRACHA in predicting aggressive behavior, and suggest links between salivary hormones and aggression by children who undergo psychiatric hospitalization.

Appraising risk factors of aggression in children and adolescents at psychiatric inpatient units.

This study examined predictors of aggression and assessed whether different subgroups of children and young people (CYP) display varying risks of aggressive incidents during hospitalization. Data from 10,090 children admitted to the psychiatric inpatient units of Cincinnati Children's Hospital between April 2010 and June 2021 were analysed. Multivariable logistic regression models were used to determine significant predictors associated with aggression, followed by average marginal effects and cluster analyses to rank and establish clusters by the order of predictor importance. About 32.5% reported positive history of an aggressive incident. The mean BRACHA score was doubled compared to those without a prior history. The primary analysis showed that both younger and male CYPs had higher odds of aggressive incidents. We also found that CYP with an African descent, not being able to live with both biological parents, those who reported positive history of psychiatric hospitalisation, and prior externalising behaviours had higher odds of aggressive incidents. These findings have important clinical and public health implications, as they provide valuable knowledge for healthcare professionals to improve prevention strategies for aggression amongst this vulnerable population.

Evidence-based recommendations for the treatment of aggression in pediatric patients with attention deficit hyperactivity disorder.

An evidence-based practice project was completed to develop best practice recommendations for the treatment of aggression in children and adolescents with attention deficit hyperactivity disorder (ADHD). Ovid Medline, PsychInfo, the National Guidelines Clearinghouse, and the Cochrane Database of Systematic Reviews were searched with limits set for English language, years 1996 to January 2010. A search of the pediatric literature was conducted for synthesized evidence in the form of meta-analyses, systematic reviews, or practice guidelines related to the treatment of aggression in children and adolescents with attention deficit hyperactivity disorder. Data were extracted using the LEGEND system. Three evidence-based care recommendations for the management of aggression in children and adolescents with ADHD were developed with an associated grade for the body of evidence. First-line pharmacotherapy for aggressive behavior in children and adolescents with ADHD should be ADHD medications. Additional research is needed to evaluate the efficacy of psychiatric medications on signs of aggression within the context of ADHD.

Predicting the time trend of first episodes of aggressive behaviors in pediatric psychiatric inpatient units.

The goal of the current study is to assess whether the scores of Brief Rating of Aggression by Children and Adolescents (BRACHA) at the emergency room (ER) can predict the aggressive incidents at pediatric psychiatric inpatient units. The study aims to identify predictors for two outcome measurements: 1) hazard rates for the first aggressive incident and 2) numbers of days between admission and the first aggressive incident, using the Cox regression model and Poisson regression model, respectively. The clinical records of a total of 5,610 adolescents admitted into the pediatric psychiatric inpatient units of Cincinnati Children's Hospital Medical Center were extracted for the analysis. The aggressive incident was defined as a score >0 from any category of the Overt Aggression Scale (OAS) and the high-aggressive incident was defined as a score ≥ 2 from any category of the OAS. The results indicate that the BRACHA score was not associated with high-aggressive incidents (hazard ratio: 0.98, p = 0.7543). Similarly, the BRACHA scores was only associated with the number of days from admission to the first aggressive incident (Poisson regression coefficient: 0.24, p < 0.0001) but not the number of days from admission to the first high-aggressive incident (Poisson regression coefficient: 0.03, p = 0.3994). Furthermore, the second peak of first aggressive incidents during the hospitalization highlights the importance of interventions at the end of the inpatient treatment course. To summarize, BRACHA scores based on initial assessments at the ER could correlate with first aggressive incidents, but not the first high-aggressive incidents.
