ADHD Symptomology and Prescription Stimulant Misuse in College Students

Attention-Deficit Hyperactivity Disorder (ADHD) is a neurological disorder characterized by developmentally inappropriate levels of hyperactivity/impulsivity and inattention. These symptoms result in impairments for individuals across multiple settings and are developmentally inappropriate. While common during childhood, symptoms have been shown to persist into adulthood for 50% or more of those diagnosed before reaching age 18. Although prescription stimulants have been shown to benefit those with ADHD, increased popularity of prescription stimulant misuse among those without ADHD has been reported, despite the potentially harmful side effects that may accompany this use. Specifically, nonmedical use of prescription stimulants during adolescence led to increased risk of crime commitment and increased risk for subsequent addictions to other substances. Despite the negative effects of prescription stimulants on those misusing them, as many as 7% of undergraduate college students reported prescription stimulant medication misuse. The present NIH R01 funded study, Trajectories Related to ADHD in College (TRAC) is a 5-year longitudinal study conducted by Dr. Arthur Anastopoulos at the University of North Carolina at Greensboro (Lead Principal Investigator), Dr. George DuPaul at Lehigh University (Co-Principal Investigator), and Dr. Lisa Weyandt at the University of Rhode Island (Co-Principal Investigator). Through my work on this study, it became clear that although research concerning the patterns of misuse among college students has been performed and documented, the association between those with ADHD and nonmedical use of prescription stimulants has not been well studied. More specifically, research exploring the relationship between the severity of ADHD symptoms and prescription stimulant misuse is sparse. Therefore, the aim of this honors thesis is to assess the misuse among students both with, and without, ADHD, and to explore whether males and females differ in reported rates of prescription stimulant misuse

College Students\u27 Perceptions of Professor/Instructor Bullying: Questionnaire Development and Psychometric Properties

Objective: This study developed and examined the psychometric properties of a newly formed measure designed to assess professor/instructor bullying, as well as teacher bullying occurring prior to college. Additionally, prevalence of instructor bullying and characteristics related to victims of instructor bullying were examined. Participants: Participants were 337 college students recruited in 2012 from a northeastern university. Methods: An online questionnaire was administered to college students. A split-half, cross-validation approach was employed for measurement development. Results: The measure demonstrated strong criterion validity and internal consistency. Approximately half of students reported witnessing professor/instructor bullying and 18% reported being bullied by a professor/instructor. Report of teacher bullying occurring prior to college was related to professor/instructor bullying in college, and sex was a moderating variable. Conclusion: College students perceive instructor bullying as occurring but may not know how to properly address it. Prevention efforts should be made by university administrators, faculty, and staff

Neurocognitive enhancement or impairment? A systematic meta-analysis of prescription stimulant effects on processing speed, decision-making, planning, and cognitive perseveration

Increasing numbers of adults, particularly college students, are misusing prescription stimulants primarily for cognitive/academic enhancement, so it is critical to explore whether empirical findings support neurocognitive benefits of prescription stimulants. Previous meta-analytic studies have supported small benefits from prescription stimulants for the cognitive domains of inhibitory control and memory; however, no meta-analytic studies have examined the effects on processing speed or the potential impairment on other domains of cognition, including planning, decision-making, and cognitive perseveration. Therefore, the present study conducted a meta-analysis of the available literature examining the effects of prescription stimulants on specific measures of processing speed, planning, decision-making, and cognitive perseveration among healthy adult populations. The meta-analysis results indicated a positive influence of prescription stimulant medication on processing speed accuracy, with an overall mean effect size of g = 0.282 (95% CI [0.077, 0.488]; n = 345). Neither improvements nor impairments were revealed for planning time, planning accuracy, advantageous decision-making, or cognitive perseveration; however, findings are limited by the small number of studies examining these outcomes. Findings support that prescription stimulant medication may indeed act as a neurocognitive enhancer for accuracy measures of processing speed without impeding other areas of cognition. Considering that adults are already engaging in illegal use of prescription stimulants for academic enhancement, as well as the potential for stimulant misuse to have serious side effects, the establishment of public policies informed by interdisciplinary research surrounding this issue, whether restrictive or liberal, is of critical importance

First-Year GPA and Academic Service Use Among College Students With and Without ADHD

Objective: ADHD is a chronic neurodevelopmental disorder that typically results in persistent academic difficulties over time. Although most colleges offer support services, students often do not use the available services or those to which they are entitled. The present study examined predictors of academic performance among college students with and without ADHD. In addition, the rate, predictors, and outcomes of academic service use were explored. Methods: A series of multivariate analyses of variance (MANOVAs) and regression analyses were conducted using SPSS v. 21 ® software. Results: First year college students with ADHD earned significantly lower grade point averages (GPAs) relative to students without ADHD. Additionally, ADHD combined with other disorders, but not ADHD alone, predicted higher rates of service use relative to students without ADHD. Finally, the findings suggest that typically available academic services are not independently related to GPA among first-year college students with or without ADHD. Conclusion: This study replicates previous work demonstrating significantly lower GPAs among a rigorously defined sample of students with ADHD relative to students without ADHD. Second, this study indicates that traditional predictors of college success may be less meaningful for students with ADHD relative to those without ADHD. Finally, additional research needs to be conducted regarding the use and effectiveness of academic services on college campuses

Self-Injurious Thoughts and Behaviors Among College Students: A Latent Class Analysis

This study explored emerging typologies of self-injurious thoughts and behaviors and how they relate to known psychological and cognitive correlates. Latent class analysis was employed to identify subgroups of college students (n = 626, mean age = 20, 73% female, and 83% White) based on history of self-injurious thoughts and behaviors. Differences among classes were tested to examine their associations with suicidal ideation, fearlessness of death, depression/hopelessness, thwarted belongingness, problems with alcohol or drugs, behavioral inhibition, and emotional control. Results of the latent class analysis supported a 3-class solution, with students classified as being likely to have (1) no history of any self-injurious thoughts and behaviors (78%); (2) a history of all self-injurious thoughts and behaviors (8%); or (3) a history of suicidal ideation, plan, and non-suicidal self-injurious thoughts and behaviors, but not suicide attempt (13%). Findings examining correlates of self-injurious thoughts and behaviors highlight the importance of fearlessness of death for distinguishing suicide attempters from non-attempters. Attention to mental health and suicide prevention initiatives should remain a critical priority across college campuses

Nonmedical Prescription Opioid Use among a Sample of College Students: Prevalence and Predictors

Nonmedical use of prescription opioid medication (NMPO) in the United States is a public health crisis, resulting in high rates of emergency room visits, morbidity, and mortality. The purpose of this study was to explore prevalence estimates and correlates of NMPO among a convenience sample of college students in the northeast and southeast regions of the US to help generate directions for future research. Motivations for misuse, age of onset, access, concomitant substance use, and individual factors were investigated among a sample of undergraduate students from two universities. Participants (N = 847) completed a battery of various self-report measures. Findings revealed that 7.7% (Southeastern University) and 12.8% of students (Northeastern University) reported lifetime NMPO, whereas past-month NMPO was reported by 0.8% and 0.9% of participants, respectively. Lifetime history of regularly using alcohol, nonmedical use of benzodiazepine medication, nonmedical use of prescription stimulants, symptoms of depression and anxiety, and executive functioning (i.e., metacognition and behavioral regulation) were significantly related to lifetime history of NMPO in this college sample. These findings offer several potential subsequent lines of investigation regarding the associations between various demographic and psychological factors and NMPO. Future research is needed to help identify college students who are at risk of NMPO

An Examination of Prescription Stimulant Misuse and Psychological Variables Among Sorority and Fraternity College Populations

Objective: The objective of this study was to examine nonmedical stimulant use among fraternity/sorority members and nonmembers and whether psychological variables (e.g., internal restlessness, depression, anxiety, and stress) were related to nonmedical stimulant use. Method: The sample consisted of 1,033 undergraduate students from five universities located in the northeastern, southeastern, northwestern, southwestern, and midwestern regions of the United States. Results: The findings revealed that fraternity and sorority members reported a higher rate of nonmedical stimulant use than nonmembers. In addition, regression analyses revealed that higher ratings of anxiety, stress, internal impulsivity, and internal restlessness significantly predicted nonmedical stimulant use. Conclusion: Current findings support further examination of nonmedical stimulant use among other college student subpopulations (i.e., athletic teams, honor societies, residence halls). In addition, there is a strong need to develop research-based intervention and preventive measures that target college populations identified as being at risk for nonmedical stimulant use. © 2013 SAGE Publications

ADHD in College Students

Objective: According to the American Psychiatric Association, 3% to 7% of the school-age population has ADHD and many children continue to display significant symptoms throughout adolescences and adulthood. Relative to the childhood literature, less is known about ADHD in adults, especially college students with ADHD. The principle purpose of this review articles is to summarize the major research findings concerning ADHD in the college student population with regard to prevalence of symptoms, neuropsychological and psychological functioning. Overall, findings suggest that college students with ADHD are at greater risk for academic and psychological difficulties, and they perform similar to non-ADHD controls on many neuropsychological tasks. These findings are preliminary, however, and are tempered by the small number of studies that have been conducted as well as the methodological limitations of these studies. Conclusion: Future research using larger sample sizes, rigorous assessment criteria, and a longitudinal design is needed to better understand the psychological, academic, and neuropsychological functioning of college students with ADHD. Studies are also needed to elucidate the effects of pharmacological and nonpharmacological effects of treatment on the functioning of college students with this disorder
