• School-Based Supportive Practices and High School Student Suicide Rates. The Journal of adolescent health : official publication of the Society for Adolescent Medicine Halkett, A. E., Ethier, K. A., Roman, I., Klein, J. D. 2026

  Abstract

  We examined whether school-based gay, lesbian, bisexual, transgender, questioning, or other (LGBTQ +) supportive practices implemented in 2022 are associated with lower rates of suicide attempts among high-school students in 2023.Cross-sectional state-level survey data from Centers for Disease Control and Prevention's 2022 School Health Profiles and 2023 Youth Risk Behavior Surveys were concatenated into one aggregate dataset. Associations between state-level rates of suicide attempts among high school students and 12 LGBTQ + supportive practices were analyzed using bootstrapped Pearson correlations with bias correction.For each specific practice, a higher state-level percentage of schools reporting implementation in 2022 was correlated with lower rates of suicide attempts among high school students in 2023.Greater state-level implementation of school-based LGBTQ + supportive practices is correlated with lower rates of reported suicide attempts among students the subsequent year. Establishing LGBTQ + supportive practices in schools may facilitate an environment that offers protective mental health benefits for all students regardless of sexual or gender identity.

• Time Alone During Health Visits for Adolescents and Young Adults: Secondary Analysis of a Nonrepresentative Global Youth Consultation. The Journal of adolescent health : official publication of the Society for Adolescent Medicine Klein, J. D., Halkett, A. E., Turetsky, R., Divala, T., Sawyer, S. M., Baltag, V. 2026

  Abstract

  The World Health Organization (WHO) revised the Global Standards for Quality Health Care Services for Adolescents and a linked Adolescent Health Competencies documents in 2025. Young people across the world informed these revisions through a global online consultation about their health-care experiences. We examine whether these young people reported receiving time alone with their clinician at their last health-care visit.We conducted a secondary analysis of WHO consultation data from a nonrepresentative sample (N = 406) of young people (aged 10-24 years) from 64 countries spanning all 6 UN regions. Respondents completed an anonymous survey available in 6 languages between March 2024 and June 2024 about their health-care experiences.Overall, 79.2% of participants (N = 309/390, missing N = 16) reported having a visit with a health-care provider within the last 2 years, of whom 73.3% (N = 198/270, missing N = 39) reported time alone with their provider at their last visit. Rates did not differ by gender, rural versus urban settings, United Nations region, or country income group. Under 18 year olds were less likely than those 18 years or older to report time alone at their last visit (35.5% vs. 78.2%, x2 = 25.7, p < .001). Youth accompanied by a parent or caregiver were also less likely to report time alone compared to unaccompanied youth (52.0% vs. 88.0%, x2 = 39.3, p < .001), regardless of age.Younger age and parental attendance at health-care visits were associated with lower likelihood of having had time alone with providers. Greater attention is needed within health systems to ensure that health services meet WHO standards around guidelines for confidential care.

• Problematic social Internet use and associations with ADHD symptoms in girls: a longitudinal observational study BMC PUBLIC HEALTH Halkett, A., Hinshaw, S. P. 2024; 24 (1): 2850

  Abstract

  Problematic Internet use (i.e., Internet use that disrupts functioning in other important domains; PIU) is increasingly prevalent worldwide, particularly among youth. One form of PIU relates specifically to interpersonal interaction and communication, deemed social PIU. Social PIU has been linked to various forms of psychopathology, including attention-deficit/hyperactivity disorder (ADHD). Yet with limited longitudinal research, the direction of this association remains unclear. Moreover, little research investigates whether social PIU is linked to one or both symptom dimensions of ADHD (inattention vs. hyperactivity/impulsivity).The present study utilized data from the largest extant longitudinal study of girls with childhood-diagnosed ADHD (N = 228). Linear regression and structural equation models were used to analyze social PIU as both a prospective predictor and outcome of ADHD symptoms.Inattentive ADHD symptoms were positively associated with concurrent social PIU in initial regression models but were non-significant in path analyses. Social PIU was only marginally significant in predicting subsequent inattention six years later. Symptoms of hyperactivity/impulsivity were unrelated to social PIU among girls at either time point.Inattentive ADHD symptoms were initially positively linked to concurrent problems with social Internet use, but bidirectional associations were non-significant in path analyses. Relations between PIU and ADHD in girls may be less robust than previously thought, although further longitudinal research with clinical samples is needed to clarify which groups of adolescents are particularly vulnerable to social PIU and its long-term effects.

• The Relation Between Mastery, Anticipated Stigma and Depression Among Older Adults in a Primary Care Setting. The Journal of nervous and mental disease Raeifar, E., Halkett, A., Lohman, M. C., Sirey, J. A. 2017; 205 (10): 801-804

  Abstract

  The current study evaluates the interaction between mastery, depression, and psychological barriers to care among older adults in a primary care setting, including the longitudinal effects of anticipated stigma and mastery on depressive symptoms. The sample was composed of 70 depressed older adults (age ≥ 60) who were newly recommended antidepressant treatment by their physicians. This cohort is part of a larger study examining the usefulness of the Treatment Initiation and Participation program to improve medication adherence. Anticipated stigma significantly predicted greater depression among older adults with low mastery, but not among those with high mastery. Mastery was found to moderate the relationship between anticipated stigma and depressive symptoms among older adults. Increased mastery over 28 weeks was also associated with greater reductions in depressive symptoms at follow-up, controlling for antidepressant strength and adherence. Bolstering older adults' sense of mastery in treatment could provide a source of resilience for older adults facing depression.

• PROTECT: A Pilot Program to Integrate Mental Health Treatment Into Elder Abuse Services for Older Women. Journal of elder abuse & neglect Sirey, J. A., Halkett, A., Chambers, S., Salamone, A., Bruce, M. L., Raue, P. J., Berman, J. 2015; 27 (4-5): 438-53

  Abstract

  The goal of this pilot program was to test the usefulness of adapted Problem-Solving Therapy (PST) and anxiety management, called PROTECT, integrated into elder abuse services to reduce depression and improve self-efficacy. Depressed women victims were randomized to receive elder abuse resolution services combined with either PROTECT or a mental health referral. At follow-up, the PROTECT group showed greater reduction in depressive symptoms and endorsed greater improved self-efficacy in problem-solving when compared to those in the Referral condition. These preliminary findings support the potential usefulness of PROTECT to alleviate depressive symptoms and enhance personal resources among abused older women.
