Adolescent Sleep Quality and Alcohol Use: An Initial Examination of the Serial Indirect Effects of Anxiety Symptoms and Coping Motives for Alcohol Use

Background: Insufficient sleep and insomnia are associated with alcohol use as well as anxiety during adolescence and young adulthood. A negative reinforcement path to explain the association between sleep difficulties and alcohol misuse has been proposed. Within this pathway, it is speculated that while sober, insomnia and insufficient sleep lead to increased anxiety as well as anxiolytic responses to alcohol, thereby increasing the risk for both alcohol use and alcohol use problems. No work to date has examined the negative reinforcement path to alcohol use among adolescents who have consumed alcohol. Objectives: The current study aims to address this gap in the literature by examining if sleep quality is related to adolescent alcohol use problems and frequency through serial indirect effects of adolescent anxiety symptoms and coping motives for alcohol use. A total of 147 adolescents between the ages of 13 and 18 years (Mage = 16.31; SD = 0.96) from all geographic regions in the US were recruited using social media platforms (i.e., Facebook and Instagram). Participants who reported having tried alcohol at least once completed self-report measures to examine sleep quality, anxiety symptoms, alcohol use problems, alcohol use frequency, and coping motives for alcohol use. Results: Adolescent sleep quality was found to be associated with higher levels of both alcohol use problems and alcohol use frequency through the serial indirect effect of anxiety symptoms and coping motives for alcohol use. Conclusions: Overall, these findings represent a step towards understanding the complex relationship between sleep quality, alcohol, anxiety, and coping motives among adolescents.

Adolescent Alcohol and Stress Exposure Rewires Key Cortical Neurocircuitry

Human adolescence is a period of development characterized by wide ranging emotions and behavioral risk taking, including binge drinking (Konrad et al., 2013). These behavioral manifestations of adolescence are complemented by growth in the neuroarchitecture of the brain, including synaptic pruning (Spear, 2013) and increases in overall white matter volume (Perrin et al., 2008). During this period of profound physiological maturation, the adolescent brain has a unique vulnerability to negative perturbations. Alcohol consumption and stress exposure, both of which are heightened during adolescence, can individually and synergistically alter these neurodevelopmental trajectories in positive and negative ways (conferring both resiliency and susceptibility) and influence already changing neurotransmitter systems and circuits. Importantly, the literature is rapidly changing and evolving in our understanding of basal sex differences in the brain, as well as the interaction between biological sex and life experiences. The animal literature provides the distinctive opportunity to explore sex-specific stress- and alcohol- induced changes in neurocircuits on a relatively rapid time scale. In addition, animal models allow for the investigation of individual neurons and signaling molecules otherwise inaccessible in the human brain. Here, we review the human and rodent literature with a focus on cortical development, neurotransmitters, peptides, and steroids, to characterize the field's current understanding of the interaction between adolescence, biological sex, and exposure to stress and alcohol.

Research Review: Pediatric anxiety disorders - what have we learnt in the last 10 years?

BACKGROUND

Anxiety disorders first emerge during the critical developmental periods of childhood and adolescence. This review synthesizes recent findings on the prevalence, risk factors, and course of the anxiety disorders; and their neurobiology and treatment.

METHODS

For this review, searches were conducted using PubMed, PsycINFO, and clinicaltrials.gov. Findings related to the epidemiology, neurobiology, risk factors, and treatment of pediatric anxiety disorders were then summarized.

FINDINGS

Anxiety disorders are high prevalence, and early-onset conditions associated with multiple risk factors including early inhibited temperament, environment stress, and structural and functional abnormalities in the prefrontal-amygdala circuitry as well as the default mode and salience networks. The anxiety disorders are effectively treated with cognitive behavioral therapy (CBT), selective serotonin reuptake inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs).

CONCLUSIONS

Anxiety disorders are high prevalence, early-onset conditions associated with a distinct neurobiological fingerprint, and are consistently responsive to treatment. Questions remain regarding who is at risk of developing anxiety disorders as well as the way in which neurobiology predicts treatment response.

Perceived control of anxiety as a moderator in the relationship between anxiety sensitivity and problematic alcohol use among adolescents

The current study examined perceived control over anxiety as a moderator in the relationship between AS and (1) alcohol use frequency and (2) binge drinking frequency among 80 community-recruited adolescents (M_age = 15.40; 40% female). Eighty-five percent of adolescents reported consuming an alcohol beverage, while 39.5% reported binge drinking. Results indicated significant interactions between AS and perceived control. More specifically, when perceived control was low, higher anxiety sensitivity was related to increased frequency of alcohol use days, but not with binge drinking days. Alternatively, when perceived control over anxiety was high, elevated anxiety sensitivity was associated with a decreased in binge drinking days, but not with alcohol use days. Findings suggest that influence of perceived control over anxiety may be another important, malleable factor that should be considered in future etiological and intervention-oriented work targeting anxiety sensitivity and alcohol misuse among adolescence.
