Objective: This study aimed to examine whether parent–child interaction therapy (PCIT), compared with other therapy modalities, was associated with differences in substance use and psychiatric outcomes in a cohort of children with attention-deficit/hyperactivity disorder (ADHD). Methods: This retrospective cohort study was conducted using medical record data from the Rochester Epidemiology Project (REP). The sample included 643 children aged ≤7 years who were diagnosed with ADHD and received either stimulant or nonstimulant medication, along with psychosocial therapy. Participants were categorized into two groups: those who documented exposure to PCIT versus other therapy modalities such as behavioral management, play therapy, cognitive behavioral therapy, parent management training, occupational therapy, speech therapy, parenting class, applied behavior analysis, and social skills training. Conditional logistic regression models were used to examine differences in baseline characteristics and outcomes between the two treatment groups. Results: Individuals in the PCIT group were more likely to have private insurance (66% vs. 57%; p = 0.016) and to fall into higher socioeconomic status quartiles ( p = 0.024) at baseline. PCIT recipients also had a higher prevalence of emotional and behavioral disturbances at baseline (40% vs. 25%; p < 0.001). The median age of the participants at follow-up was 19.6 years, indicating a median follow-up period of approximately 13 years from the initiation of treatment. At follow-up, the PCIT group demonstrated higher rates of problematic alcohol (24% vs. 17%; HR = 1.50, 95% CI: [1.02, 2.20]; p = 0.038) and cannabis use (25% vs. 18%; HR = 1.48, 95% CI: [1.03, 2.15]; p = 0.037). However, after controlling for covariates in the adjusted model, no statistically significant differences emerged between the groups across any substance use outcome. No significant differences were observed in other psychiatric diagnoses or mental health service utilization. Conclusions: Findings indicate that individuals who documented exposure to PCIT demonstrated elevated rates of alcohol and cannabis use in young adulthood, but had no other differences in psychiatric outcomes. While this aligns with prior literature reporting increased substance use risk in ADHD populations, our study cannot confirm this association relative to non-ADHD controls because such a comparison was not included. These associations likely reflect underlying differences in clinical severity and clinical comorbidities at baseline, rather than a direct effect of PCIT. Further investigation is warranted to determine the treatment effects based on baseline risk factors.

ImportanceThe rates of suicide and suicide attempts are rising precipitously among early adolescents aged 10 to 14 years in the US. While suicide attempts in this age group are more common and associated with lower lethality than in older age groups, very little is known about these individuals’ long-term social and psychiatric outcomes.ObjectivesTo examine the adult outcomes of individuals making index suicide attempts that came to medical attention between the ages of 10 and 14 years.Design, Setting, and ParticipantsThis population-based cohort constitutes a subsample (n = 164) of a previously reported retrospective-prospective study examining individuals who made index suicide attempts during a 22-year period (1986-2007) in Olmsted County, Minnesota.Main Outcomes and MeasuresTo collect outcome measures, the medical records of all individuals were queried until March 31, 2023, comprising up to 36 years of follow-up data after the index attempt. Measures included current social, psychiatric, and mortality outcomes as well as lifetime measures of psychiatric hospitalizations and repeat suicide attempts. K-means clustering generated adult groupings based on aggregates of psychiatric hospitalizations and repeat attempts. Multivariable logistic regression identified index attempt factors associated with poor adult outcomes.ResultsOf 164 individuals aged 10 to 14 years who made index attempts (128 [78.0%] female; mean [SD] age at index attempt, 13.7 [1.1] years), 3 (1.8%) died on the index attempt. In the follow-up period, no individuals died by suicide. K-means clustering generated a 2-group solution reflecting low (120 [80%]) and high (30 [20%]) rates of adult psychopathology. While a minority of the sample belonged to the high-rate group, characterized by multiple repeat attempts and hospitalizations, the majority had favorable social indicators and fewer reattempts and hospitalizations. Poor adult outcomes were associated with being male (odds ratio, 2.44; 95% CI, 1.00-5.80; P = .04) and having a psychiatric diagnosis prior to the index attempt (odds ratio, 3.27; 95% CI, 1.42-8.07; P = .007).Conclusions and RelevanceIn this sample of early adolescents with index suicide attempts followed into adulthood, all who died by suicide did so on the index attempt. While a small number of individuals went on to develop chronic severe psychopathology, the majority demonstrated little evidence of long-term impairment. Given this discrepancy, future studies should focus on using risk stratification after index attempts to direct postvention resources toward adolescents more susceptible to poor outcomes.

Abstract Limited empirical data have been available on the adult sequelae of childhood homelessness. Using nationally representative data from the National Epidemiologic Survey of Alcohol and Related Conditions-III, we compared a hierarchy of adults who were never homeless, those who were only homeless as children, and those who were homeless both as children and adults, hypothesizing greater adversity as one moved up the three-level hierarchy on sociodemographic, behavioral, and lifetime mental health diagnostic characteristics. As a further evaluation of the status of adults who were homeless as both children and adults, we compared this highest risk group to those who had been homeless only as adults. Individuals who experienced childhood homelessness were 46.9 times more likely than others to also experience adult homelessness. Testing the hierarchical hypothesis, compared with those who were never homeless, individuals who experienced homelessness only as children reported numerous associated disadvantages, including childhood sexual abuse/neglect, parental adversities, adult incarceration, psychiatric disorders, and low academic achievement/employment. Those reporting both child and adult homelessness, in contrast to childhood homelessness alone, additionally met the criteria for multiple substance use disorders, confirming our hierarchical hypothesis. Those reporting both child and adult homelessness also showed more numerous social and psychiatric problems when compared with those experiencing homelessness for the first time as adults. This study demonstrates how homelessness in childhood is associated with extensive social and psychiatric adversities in both childhood and adulthood.

Importance There has been increasing concern about the burden of mental health problems among youth, especially since the COVID-19 pandemic. Trends in mental health–related emergency department (ED) visits are an important indicator of unmet outpatient mental health needs. Objective To estimate annual trends in mental health–related ED visits among US children, adolescents, and young adults between 2011 and 2020. Design, Setting, and Participants Data from 2011 to 2020 in the National Hospital Ambulatory Medical Care Survey, an annual cross-sectional national probability sample survey of EDs, was used to examine mental health–related visits for youths aged 6 to 24 years (unweighted = 49 515). Main Outcomes and Measures Mental health–related ED visits included visits associated with psychiatric or substance use disorders and were identified by International Classification of Diseases-Ninth Revision, Clinical Modification ( ICD-9-CM ; 2011-2015) and ICD-10-CM (2016-2020) discharge diagnosis codes or by reason-for-visit (RFV) codes. We estimated the annual proportion of mental health–related pediatric ED visits from 2011 to 2020. Subgroup analyses were performed by demographics and broad psychiatric diagnoses. Multivariable-adjusted logistic regression analyses estimated factors independently associated with mental health–related ED visits controlling for period effects. Results From 2011 to 2020, the weighted number of pediatric mental health–related visits increased from 4.8 million (7.7% of all pediatric ED visits) to 7.5 million (13.1% of all ED visits) with an average annual percent change of 8.0% (95% CI, 6.1%-10.1%; P &amp;lt; .001). Significant linearly increasing trends were seen among children, adolescents, and young adults, with the greatest increase among adolescents and across sex and race and ethnicity. While all types of mental health–related visits significantly increased, suicide-related visits demonstrated the greatest increase from 0.9% to 4.2% of all pediatric ED visits (average annual percent change, 23.1% [95% CI, 19.0%-27.5%]; P &amp;lt; .001). Conclusions and Relevance Over the last 10 years, the proportion of pediatric ED visits for mental health reasons has approximately doubled, including a 5-fold increase in suicide-related visits. These findings underscore an urgent need to improve crisis and emergency mental health service capacity for young people, especially for children experiencing suicidal symptoms.
