Article Synopsis
  • The study investigates how using small datasets to select an optimal cutoff score for the Patient Health Questionnaire-9 (PHQ-9) can lead to inaccurate results.
  • Researchers evaluated whether data-driven methods for cutoff selection resulted in scores that were significantly different from the true population optimal score and if these methods produced biased accuracy estimates.
  • Findings showed that many small studies frequently failed to identify the correct optimal cutoff score, particularly in smaller samples, leading to an overestimation of test sensitivity.

Article Synopsis
  • - The study examines how mental health (MH) and substance use (SU) treatment impacts women's alcohol use progression and recovery, focusing on those who currently drink or have a history of alcohol use.
  • - Analysis of data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) revealed that minority women were less likely to receive MH/SU treatment compared to White women, affecting their recovery outcomes.
  • - Results indicate that women who received treatment prior to the study were more likely to transition from moderate alcohol problems to no problems, highlighting the importance of access to treatment for better health outcomes.

Objective: An expert consensus approach was used to determine the adequacy of children's psychopharmacology and to examine whether adequacy varied by demographic or clinical characteristics.

Methods: Data were from the baseline interview of 601 children, ages 6-12 years, who had visited one of nine outpatient mental health clinics and participated in the Longitudinal Assessment of Manic Symptoms study. Children and parents were interviewed with the Kiddie Schedule for Affective Disorders and Schizophrenia and the Service Assessment for Children and Adolescents to assess the child's psychiatric symptoms and lifetime mental health services use, respectively.

Article Synopsis
  • The study compares the effectiveness of two screening tools for major depression: the seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item version (HADS-T), which includes anxiety items and takes longer to complete.
  • An analysis of data from 20,700 participants revealed that both HADS-D and HADS-T had similar sensitivity and specificity for detecting major depression, with optimal cutoffs being ≥7 for HADS-D and ≥15 for HADS-T.
  • Overall, while both tools are accurate, the shorter HADS-D is preferred in most clinical settings due to its simplicity and time efficiency.

Article Synopsis
  • Adolescent internalizing symptoms, such as depression and low self-esteem, are rising in the U.S., and the study aimed to explore if changes in parenting practices contribute to this trend.
  • Analysis of data from nearly a million participants (1991-2019) revealed that most parental practices remained stable, except for a slight increase in parental knowledge about their adolescent's whereabouts.
  • The study found that higher parental knowledge and monitoring are associated with lower levels of internalizing symptoms, suggesting that promoting stable parenting practices could help address adolescent mental health issues.

During the COVID-19 pandemic, news and social media outlets have played a major role in dissemination of information. This analysis aimed to study the association between trust in social and traditional media and experiences of mental distress among a representative sample of US adults. Data for this study came from National Pandemic Pulse, a cross-sectional, nationally representative survey that sampled participants on the Dynata platform.

The COVID-19 pandemic has contributed to poor health due to a decrease in healthcare utilization and those with mental health problems may be impacted. For this analysis, data came from a cross-sectional, nationally representative December 2020 survey. Logistic regression analyses examined associations between (1) mental distress and delayed medical visits, (2) mental distress and missed prescription refills, controlling for sociodemographics, pre-existing chronic conditions, and access to health insurance.

Introduction: Longitudinal research assessing whether mood disorders predict substance use behaviors is limited. We extend our prior work evaluating transition patterns with alcohol use to assess patterns with alcohol and drug use problems.

Method: Using National Epidemiologic Survey on Alcohol and Related Conditions prospective data, waves 1 and 2, we completed latent class analyses to empirically define classes of alcohol and drug problems from DSM disorder criteria.

  • * Results showed that stricter NPIs correlated with higher levels of anxiety and depressive symptoms, though the effect was quite small.
  • * Individual NPIs affected mental health differently based on gender and age, indicating the need for governments to consider mental health support when enforcing strict interventions.

The objective of this study is to determine county-level factors associated with anxiety, depression, and isolation during the coronavirus disease 2019 (COVID-19) pandemic. This study used daily data from 23,592,355 respondents of a nationwide Facebook-based survey from April 2020 to July 2021, aggregated to the week-county level to yield 212,581 observations. Mental distress prevalences were modeled using weighted linear mixed-effects models with a county random effect.

Purpose: The objectives of the current study were to (1) assess associations between household structure (i.e., living with spouse compared to living alone, with children, or with a spouse and children), presence of children, and mental distress in April 2020 and change in mental distress (between April and August 2020); and (2) determine whether these associations are moderated by income or sex.

Background: Evidence suggests that the prevalence of self-rated psychological symptoms among children and adolescents has changed in the past two decades. Our objective was to examine if similar trends are apparent in parent-rated assessments of psychological symptoms.

Methods: Participants were a nationally-representative sample of parents who rated psychological symptoms in their children (ages 4-17) in either the 2004 (n = 9,012) or 2019 (n = 7,092) National Health Interview Survey.

Background: The COVID-19 pandemic has had an impact on mental health and alcohol use in the US, however there is little research on its impacts on cannabis use. Considering the role of cannabis as a coping strategy or self-medicating behavior, there is a need to understand how individuals who use cannabis have adapted their use amid the pandemic. Therefore, this study examined changes in self-reported cannabis use among US adults in the context of COVID-19 pandemic by (1) describing trends of use during the first 8 months of the pandemic among adults who used cannabis in this period; and (2) characterizing trends of use within sociodemographic subgroups and by state cannabis policy status.

Background: Tobacco policies, including clean indoor air laws and cigarette taxes, increase smoking cessation in part by stimulating the use of cessation treatments. We explored whether the associations between tobacco policies and treatment use varies across sociodemographic groups.

Methods: We used data from 62,165 U.

Adolescent cannabis use is an established risk factor for the development of psychosis, but the premorbid vulnerability factors and specificity versus generality of the psychotic symptom domains affected in cannabis-psychosis relationships remain incompletely understood. To improve our understanding of these relationships, we used longitudinal data to examine the individual and interactive effects of preadolescent transmissible liability to substance use disorders (SUD), measured the transmissible liability index (TLI), and adolescent cannabis use on the development of two distinct psychotic symptom domains, paranoid and schizotypal personality traits in young adulthood. We performed secondary analysis of data from the Center for Education and Drug Abuse (CEDAR) study, which longitudinally assessed offspring of men with ( = 211) and without ( = 237) lifetime history of SUD at ages 10-12, and across adolescence as they transitioned to young adulthood.

The COVID-19 pandemic may disproportionately impact parents of children with autism spectrum disorder (ASD). Loss of services and supports, heightened fears about increased infection rates, and disruption of daily routines likely adversely affect the well-being of children with ASD and their families. The goal of this study was to examine differences in psychological distress-as defined by symptoms of anxiety, depression, loneliness, and hyperarousal-between parents raising a child with ASD and parents in the US as a whole during the early stages of the pandemic (March-April 2020).
