The Impact of Mobile Technology-Delivered Interventions on Youth Well-being: Systematic Review and 3-Level Meta-analysis.

Background: Rates of mental health problems among youth are high and rising, whereas treatment seeking in this population remains low. Technology-delivered interventions (TDIs) appear to be promising avenues for broadening the reach of evidence-based interventions for youth well-being. However, to date, meta-analytic reviews on youth samples have primarily been limited to computer and internet interventions, whereas meta-analytic evidence on mobile TDIs (mTDIs), largely comprising mobile apps for smartphones and tablets, have primarily focused on adult samples.

Finding Silver Linings: A Mixed Methods Analysis of COVID-19's Challenges and Opportunities for College Students' Functioning and Outlook.

This study examines the impact of the COVID-19 pandemic on college students' lives. A mixed methods approach, analyzing open- and closed-ended questions about challenges and opportunities, reveals numerous ways in which the pandemic has impacted students in general and differentially by gender, sexual orientation, race/ethnicity, and family income. Cisgender male and heterosexual students generally reported less of a mental health impact from the pandemic.

Sex Differences in Neuropsychological Functioning are Domain-Specific in Adolescent and Young Adult Regular Cannabis Users.

Objective: Adolescence into young adulthood represents a sensitive period in which brain development significantly diverges by sex. Regular cannabis use by young people is associated with neuropsychological vulnerabilities, but the potential impact of sex on these relationships is unclear.

Method: In a cross-sectional study, we examined sex differences in multi-domain neuropsychological functioning using the Cambridge Neuropsychological Test Automated Battery (CANTAB) and tested whether sex moderated the relationship between cognitive performance and age of initiation, frequency of cannabis use, amount of cannabis use, and withdrawal symptoms in at least weekly adolescent and young adult cannabis users (n = 171; aged 13-25 years; 46.

Alcohol substitution during one month of cannabis abstinence among non-treatment seeking youth.

Objective: Cannabis and alcohol use are correlated behaviors among youth. It is not known whether discontinuation of cannabis use is associated with changes in alcohol use. This study assessed alcohol use in youth before, during, and after 4 weeks of paid cannabis abstinence.

Behavioral and Neural Markers of Emotion Competence as Predictors of Later Psychopathology in Children With and Without Hyperactive/Impulsive Symptoms.

We examined behavioral and neural markers of emotion competence in young children as predictors of psychopathology, and as mediators of the relation between hyperactivity/impulsivity (H/I) and psychopathology. At Time 1 (T1), children ( = 49; ages 4-7 years) with and without H/I symptoms completed a frustration task. Frustration, observed emotion, and neural activity (P1, N2, and P3 event-related potentials) were measured.

Urinary 11-nor-9-carboxy-tetrahydrocannabinol elimination in adolescent and young adult cannabis users during one month of sustained and biochemically-verified abstinence.

Background: Despite adolescents and young adults being the most frequent users of cannabis, all information on cannabis drug testing interpretation is based on data from adults.

Aims: This study aimed to define the time course of urinary 11-nor-9-carboxy-tetrahydrocannabinol (THCCOOH) excretion among 70 adolescent and young adult cannabis users during 1 month of biochemically-verified cannabis abstinence.

Methods: Urine specimens were collected at non-abstinent baseline and after 2, 3, 8, 15, 21 and 28 days of abstinence.

Suggestibility is associated with alcohol self-administration, subjective alcohol effects, and self-reported drinking behavior.

Background: Suggestibility, defined as an individual's inclination to accept and internalize messages, has not been studied in relation to alcohol use. Peer conformity, a component of suggestibility, may be related to alcohol use, as peer groups show similarities in patterns of alcohol use. Few studies have assessed how suggestibility and peer conformity relate to alcohol self-administration or to reinforcing effects of alcohol.

Cross-domain correlates of cannabis use disorder severity among young adults.

Background: Correlates of cannabis use and dependence among young adults have been widely studied. However, it is not known which factors are most strongly associated with severity of cannabis use dependence (CUD) severity. Identification of the salient correlates of CUD severity will be of increasing clinical significance as use becomes more socially normative.

One Month of Cannabis Abstinence in Adolescents and Young Adults Is Associated With Improved Memory.

Objective: Associations between adolescent cannabis use and poor neurocognitive functioning have been reported from cross-sectional studies that cannot determine causality. Prospective designs can assess whether extended cannabis abstinence has a beneficial effect on cognition.

Methods: Eighty-eight adolescents and young adults (aged 16-25 years) who used cannabis regularly were recruited from the community and a local high school between July 2015 and December 2016.
