A pilot investigation of emotional regulation difficulties and mindfulness-based strategies in manic and remitted bipolar I disorder and major depressive disorder.

Background: Both bipolar disorder and major depressive disorder are characterized by difficulties in emotion regulation. Little is known about which specific emotion regulatory patterns may be transdiagnostic versus disorder specific, and how such patterns change as a function of current mood states.

Methods: This preliminary investigation examined specific patterns of self-reported trait emotion regulation difficulties and mindfulness-based regulations strategies across four groups: remitted adults with bipolar I disorder (BD-remitted; n = 32), currently manic adults with bipolar I disorder (BD-manic; n = 19), remitted adults with major depressive disorder (MDD-remitted; n = 32), and healthy controls (CTL; n = 30).

Recent tobacco use has widespread associations with adolescent white matter microstructure.

Importance: Given the prevalence of alcohol, cannabis, and tobacco use during adolescence, it is important to explore the relative relationship of these three substances with brain structure.

Objective: To determine associations between recent alcohol, cannabis, and tobacco use and white and gray matter in a large sample of adolescents.

Design, Setting, And Participants: MRI data were collected in N = 200 adolescents ages 14-18 (M = 15.

Neural Correlates of Risky Sex and Response Inhibition in High-Risk Adolescents.

Adolescence is a neurodevelopmental period of heightened sexual risk taking. Neuroimaging can help elucidate crucial neurocognitive mechanisms underlying adolescent sexual risk behavior, yet few empirical studies have investigated this neural link. To address this gap in the literature, we examined the association between neurocognitive function during response inhibition-a known correlate of risk behaviors-and frequency of intercourse without a condom among adolescents.

Changing the Context Is Important and Necessary, but Not Sufficient, for Reducing Adolescent Risky Sexual Behavior: A Reply to Steinberg (2015).

Starting school later, keeping adolescents busy with structured programming, and making free condoms available, as Steinberg (2015) suggests, are important and necessary steps, but they are simply not sufficient if the goal is reducing sexually transmitted infections and unplanned pregnancy. We agree that the current state of affairs, which in many schools involves sexuality education using programs that are not empirically supported, is unacceptable. However, abandoning sexuality education entirely would leave adolescents ill equipped to protect themselves.

Functional activation during the Stroop is associated with recent alcohol but not marijuana use among high-risk youth.

Despite studies showing the relevance of different decision-making abilities, including response inhibition, to likelihood of using substances during adolescence, few have examined these neural processes among high-risk, substance-using youth. The current study explored associations between alcohol and marijuana use and functional activation differences during Stroop performance among a large sample (N=80) of ethnically-diverse, high-risk youth in an fMRI-based task. In the absence of associations between substance use and task behavioral performance, adolescents with greater alcohol use showed less activation during the more cognitively difficult portion of the task across clusters in bilateral cuneus and precuneus, and right and left superior temporal gyrus.

Correlates of real world executive dysfunction in bipolar I disorder.

Background: Bipolar disorder is characterized by impairments in cognitive functioning, both during acute mood episodes and periods of euthymia, which interfere with functioning. Cognitive functioning is typically assessed using laboratory-based tests, which may not capture how cognitive dysfunction is experienced in real-life settings. Little is known about the specific illness characteristics of bipolar disorder that contribute to cognitive dysfunction in everyday life.
