Psychiatric comorbidity and treatment outcomes in patients with opioid use disorder: Results from a multisite trial of buprenorphine-naloxone and methadone.

Background: Individuals treated for opioid use disorder (OUD) have high rates of psychiatric disorders potentially diminishing treatment outcomes. We examined long-term treatment experiences and outcomes by type of psychiatric disorder among participants who participated in the Starting Treatment with Agonist Replacement Therapies (START) study and its follow-up study.

Methods: We categorized the 593 participants who completed the Mini-International Neuropsychiatric Interview (MINI) during the START follow-up study into four mutually exclusive groups to indicate current psychiatric diagnosis: 1) bipolar disorder (BPD; n = 51), 2) major depressive disorder (MDD; n = 85), 3) anxiety disorder (AXD; n = 121), and 4) no comorbid mental disorder (NMD; n = 336).

Adolescent, Parent, and Provider Perspectives of a Social-Media-Based Support Tool for Parents of Teens in Treatment for Substance Use.

Adolescent substance use disorder contributes to negative psychosocial and physical health outcomes. Parents best support their child's treatment and recovery when they are equipped with knowledge and skills; however, barriers hinder parental engagement. Social-media-based groups present an opportunity for parents who may not otherwise seek support.

Long-term follow-up assessment of opioid use outcomes among individuals with comorbid mental disorders and opioid use disorder treated with buprenorphine or methadone in a randomized clinical trial.

Aims: To investigate whether reduction in opioid use differs when treated by either buprenorphine-naloxone (BUP) or methadone (MET) among adults with comorbid opioid use disorder (OUD) and mental disorders.

Design, Setting And Participants: In a randomized controlled trial, adults with OUD were randomized to 24 weeks of either BUP or MET treatment and were followed up in 3-yearly assessments. The present secondary analyses were based on 597 participants who completed all assessments.

Prospective Association of Digital Media Use with Alcohol Use Initiation and Progression Among Adolescents.

Background: Although adolescents commonly use digital media and consume alcohol , longitudinal evidence of the association between these behaviors is scant. This study examined the association between the frequency of digital media use and the subsequent initiation or progression of alcohol use. We also examined whether these associations were moderated by gender and race/ethnicity.

The Relationship Between Dating Status and Academic and Social Functioning in Middle Adolescence.

Bidirectional associations between e-cigarette use and alcohol use across adolescence.

Introduction: Evidence on prospective bidirectional associations between e-cigarette and alcohol use among adolescents can inform prevention and policy but is largely absent from the literature.

Methods: Data were drawn from a prospective cohort of students attending 10 Los Angeles high schools (N = 3396; baseline mean age = 14.1, SD = 0.

Digital media use and subsequent cannabis and tobacco product use initiation among adolescents.

Background: Digital media engagement, such as browsing the internet or social media posting, may be associated with cannabis and tobacco product use initiation among adolescents. Whether certain digital media exposure confers greater - or reduced - risk for specific cannabis or tobacco products is unknown.

Methods: Adolescents completed surveys on digital media and substance use every 6 months from 2015 to 2017 (4 waves).

Cross-Ethnic Friendships, Intergroup Attitudes, Intragroup Social Costs, and Depressive Symptoms among Asian-American and Latino-American Youth.

As American school districts become increasingly diverse, understanding the processes that promote positive intergroup relations is a critical task. The role of cross-ethnic friendships is one important factor, given the significance of these reciprocated peer relationships for social development. The current study examines the short-term longitudinal impact of cross-ethnic friendships on peer group attitudes and emotional adjustment.

Distinct Modalities of Electronic Communication and School Adjustment.

Social media platforms and instant messaging applications have a widespread presence in today's secondary schools. However, the implications of these ubiquitous communication technologies for adolescent's social functioning with peers and academic competence in the classroom are not well understood. In fact, research on adolescents' digital lives has only rarely incorporated direct assessments of adjustment in school environments.
