Neurodevelopmental Processes In The Prefrontal Cortex Derailed By Chronic Hiv-1 Viral Protein Exposure, Kristen A. Mclaurin, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Due to the widespread access to, and implementation of, combination antiretroviral therapy, individuals perinatally infected with human immunodeficiency virus type 1 (HIV-1) are living into adolescence and adulthood. Perinatally infected adolescents living with HIV-1 (pALHIV) are plagued by progressive, chronic neurocognitive impairments; the pathophysiological mechanisms underlying these deficits, however, remain understudied. A longitudinal experimental design from postnatal day (PD) 30 to PD 180 was utilized to establish the development of pyramidal neurons, and associated dendritic spines, from layers II-III of the medial prefrontal cortex (mPFC) in HIV-1 transgenic (Tg) and control animals. Three putative neuroinflammatory markers (i.e., IL-1β, IL-6, and …

Successful Weight Loss Initiation And Maintenance Among Adolescents With Overweight And Obesity: Does Age Matter?, Diana Rancourt, Chad D. Jensen, Kara Mcrae Duraccio, E. Whitney Evans, Rena R. Wing, Elissa Jelalian

Faculty Publications

Background—Treatments for adolescents with overweight/obesity demonstrate mixed success, which may be due to a lack of consideration for developmental changes during this period. Potential developmental differences in weight loss motivations, weight maintenance behaviors, and the role of parents in these efforts were examined in a sample of successful adolescent weight losers.

Methods—Participants enrolled in the Adolescent Weight Control Registry (n = 49) self-reported demographic information and weight history, reasons for weight loss and weight control, weight loss approach and weight maintenance strategies, and perceived parental involvement with weight loss. Associations between age at weight loss initiation and the aforementioned factors …

The Longitudinal Impact Of Screen Time On Adolescent Development: Moderation By Respiratory Sinus Arrhythmia, Wesley Sanders, Justin Parent, Jamie L. Abaied, Rex Forehand, Sarah M. Coyne, W. Justin Dyer

Faculty Publications

Purpose: To date, little is known about underlying psychophysiological contributions to the impact of media content and overall screen time on adolescent psychological functioning. In the present study we examine respiratory sinus arrhythmia (RSA) as a moderator of the link between specific types of media content use, overall media exposure, and the development of internalizing and aggressive symptoms in youth.

Methods: A sample of 374 adolescents (mean age = 15) reported on their media use, internalizing behavior, and aggressive behavior at time 1 (2011) and 1-year follow-up (2012). RSA reactivity was gathered during a challenging laboratory task. Path analyses were …

Preadolescent Sensation Seeking And Early Adolescent Stress Relate To At-Risk Adolescents' Substance Use By Age 15, Nora E. Charles, Charles W. Mathias, Ashley Acheson, Donald M. Dougherty

Faculty Publications

Background and aims

Substance use during adolescence can lead to the development of substance use disorders and other psychosocial problems. These negative outcomes are especially likely for individuals who use substances at earlier ages and those who engage in heavier use during adolescence, behaviors which are both more common among youth at higher risk for developing a substance use disorder, such as those with a family history of substance use disorders (FH +). Factors such as increased sensation seeking and greater exposure to stressors among FH + youth may influence these associations. Therefore, the aim of this study was to …

Altered Developmental Trajectories For Impulsivity And Sensation Seeking Among Adolescent Substance Users, Nora E. Charles, Stacy R. Ryan, Bethany C. Bray, Charles W. Mathias, Ashley Acheson, Donald M. Doherty

Faculty Publications

A number of studies have associated impulsivity and sensation seeking with level of substance use and risk for developing a substance use disorder. These relationships may be particularly apparent during adolescence, when developmental changes in impulsivity and sensation seeking occur at the same time as increased opportunities for substance use. To examine this, the current study measured impulsivity and sensation seeking from pre-adolescence to mid-adolescence in a sample of youth, the majority of whom were identified as being at risk for developing a substance use disorder based on their family history of substance use disorders. Youth were separated into those …

Pubertal Maturation Compression And Behavioral Impulsivity Among Boys At Increased Risk For Substance Use, Charles W. Mathias, Nora E. Charles, Yuanyuan Lang, Ashley Acheson, Sarah L. Lake, Stacy R. Ryan, Rene L. Olvera, Donald M. Dougherty

Faculty Publications

Objectives: While early onset of puberty among girls has been related to substance use involvement and other adverse outcomes, less research has examined pubertal development and outcomes in boys. Further, research on puberty has not been conducted in the context of other risk factors for substance use involvement such as impulsivity. To address these gaps, this study characterized boys' pubertal development from preadolescence to mid adolescence and related it to substance use risk and behavioral impulsivity.

Methods: A sample of 153 boys completed the Pubertal Development Scale to assess perception of their pubertal development relative to same-age peers …

An Evaluation Of A Smartphone–Assisted Behavioral Weight Control Intervention For Adolescents: Pilot Study, Chad D. Jensen, Kristina M. Duncombe, Mark A. Lott, Sanita L. Hunsaker, Kara Mcrae Duraccio, Susan J. Woolford

Faculty Publications

Background: The efficacy of adolescent weight control treatments is modest, and effective treatments are costly and are not widely available. Smartphones may be an effective method for delivering critical components of behavioral weight control treatment including behavioral self-monitoring.

Objective: To examine the efficacy and acceptability of a smartphone assisted adolescent behavioral weight control intervention.

Methods: A total of 16 overweight or obese adolescents (mean age=14.29 years, standard deviation=1.12) received 12 weeks of combined treatment that consisted of weekly in-person group behavioral weight control treatment sessions plus smartphone self-monitoring and daily text messaging. Subsequently they received 12 weeks of electronic-only intervention, …

Psychometric Properties Of The Adolescent Sleep Hygiene Scale, Amy Storfer-Isser, Monique K. Lebourgeois, John Harsh, Carolyn J. Tompsett, Susan Redline

Faculty Publications

This study evaluated the psychometric properties of the Adolescent Sleep Hygiene Scale (ASHS), a self-report measure assessing sleep practices theoretically important for optimal sleep. Data were collected on a community sample of 514 adolescents (16–19; 17.7 ± 0.4 years; 50% female) participating in the late adolescent examination of a longitudinal study on sleep and health. Sleep hygiene and daytime sleepiness were obtained from adolescent reports, behavior from caretaker reports, and sleep-wake estimation on weekdays from wrist actigraphy. Confirmatory factor analysis indicated the empirical and conceptually based factor structure were similar for six of the eight proposed sleep hygiene domains. Internal …

Sleep Hygiene And Sleep Quality In Italian And American Adolescents, Monique K. Lebourgeois, Flavia Giannotti, Flavia Cortesi, Amy Wolfson, John R. Harsh

Faculty Publications

This study investigated cross-cultural differences in adolescent sleep hygiene and sleep quality. Participants were 1348 students (655 males; 693 females) aged 12-17 years from public school systems in Rome, Italy (n = 776) and Southern Mississippi (n = 572). Participants completed the Adolescent Sleep-Wake Scale and the Adolescent Sleep Hygiene Scale. Reported sleep hygiene and sleep quality were significantly better for Italian than American adolescents. A moderate linear relationship was observed between sleep hygiene and sleep quality in both samples (Italians: R =.40; Americans: R =.46). Separate hierarchical multiple regression analyses showed that sleep hygiene accounted for significant variance in …
