Factor Structure of the Sexual Risk Survey Among U.S. College Students with and without ADHD: Assessing Clinical Utility with a High-Risk Population.

Young adults, particularly college students, report a higher prevalence of risky sexual behavior than the general population, increasing their likelihood for unplanned pregnancy, sexually transmitted infections (STIs), and negative psychological outcomes. Although sexual risk behavior and its consequences are a major public health concern, current prevention literature is insufficient and relies on sexual risk measures with limited psychometric support. The present study, therefore, examined the psychometric properties of a sexual risk survey (SRS; Turchik, Garske, in Arch Sex Behav 38:936-948, 2009), using data from the first year of a longitudinal study following the outcomes of college students with and without attention-deficit/hyperactivity disorder (ADHD; N = 410). Principal components analyses were conducted to assess the factorial structure of the SRS comparing results from a general college population and a college population considered to be high-risk (ADHD). Results revealed four components across both samples. Internal consistency estimates for component scores and total scores ranged from .627 to 918. Implications of the findings are discussed and suggestions for future studies are advanced.

Physiological substrates of executive functioning: a systematic review of the literature.

Executive function (EF) is a multifaceted construct that has been defined as a set of higher-order cognitive processes that allow for flexibility, self-regulation, strategic planning, and goal-directed behaviors. EFs have been studied in numerous clinical disorders using a variety of neuropsychological tasks and, more recently, neuroimaging techniques. The underlying physiological substrates of EF were historically attributed to the frontal lobes; however, recent studies suggest more widespread involvement of additional brain regions. The purpose of the present study was to conduct a systematic review (using PRISMA 2009 guidelines) of neuroimaging studies employing functional magnetic resonance imaging and diffusion tensor imaging methods investigating the physiological substrates of EFs in attention-deficit/hyperactivity disorder compared to other clinical groups and non-clinical participants. Research articles were retrieved using PsycINFO, PsycARTICLES, MEDLINE, and ScienceDirect, beginning February 2015 through May 2016. A total of 42 studies met eligibility. Of those 42 studies, 22 studies included clinical participants and 20 studies included non-clinical participants. Results revealed increased activation of the frontal brain region in the majority of non-clinical studies and approximately 50% of the clinical studies, albeit with some inconsistencies across subregions, tasks, and age groups. Implications, methodological limitations, and suggestions for future research are discussed.

Attention-Deficit Hyperactivity Disorder: Clinical Considerations for Women.

Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by hyperactivity, impulsivity, and/or inattention. Women with ADHD represent a particularly vulnerable group, given their increased risk for psychosocial and parenting difficulties. Women's health care clinicians should expect to encounter women with diagnosed and undiagnosed ADHD that may or may not be treated. Pharmacologic intervention, namely, prescription stimulants, is an important consideration for pregnant and breastfeeding women with ADHD, especially because the US Food and Drug Administration has determined that there is not enough information to confirm either harm or lack of harm to the developing fetus following exposure to these drugs. Due to the increase in use of prescription stimulants without a prescription, clinicians are also likely to encounter women misusing stimulants for a variety of reasons. This article provides an overview of ADHD diagnosis, outlines effective treatment options, and offers insight into the importance for clinicians to consider prescription stimulant misuse. Guidance concerning treatment of ADHD during pregnancy and lactation is reviewed.

The relationship between nonmedical use of prescription stimulants, executive functioning and academic outcomes.

The nonmedical use of prescription stimulants (NMUPS) is a prevalent issue among college students. The primary reason college students report NMUPS is for academic enhancement i.e., to perform better on schoolwork/tests and focus better in class. Executive functioning (EF), which includes abilities that allow for planning, cognitive flexibility, self-regulation, and goal-directed behavior, are potential mechanisms underlying academic performance. Preliminary research has revealed that college students with EF deficits are more likely to have educational difficulties and take part in risky behavior. Based on the literature, it is possible that students with EF deficits are engaging in NMUPS to help them overcome these deficits to succeed academically. Therefore, the purpose of the present study was to examine the relationship between NMUPS and EF among a sample of college students. The sample included 308 students from six public universities located in various regions of the United States. Measures used in this study were the SSQ, BDEFS and GPA. Results revealed 18.8% of the general sample reported NMUPS. Participants with clinically significant EF deficits reported significantly higher rates of NMUPS, compared to those without deficits in EF. NMUPS, however, did not moderate the relationship between EF and GPA. The present findings have implications for identifying sub-populations of college students who might be at risk for engaging in NMUPS and to improve prevention and intervention strategies aimed at reducing NMUPS. Limitations and suggestions for future research are discussed.

Neuropsychological functioning in college students with and without ADHD.

OBJECTIVE: Increasing numbers of students with attention-deficit/hyperactivity disorder (ADHD) are attending college; however, little empirical information is available concerning the functional impairment experienced by these students. Although preliminary studies suggest that college students with ADHD are more likely to experience a variety of psychosocial and academic difficulties compared to their peers without the disorder, findings regarding neuropsychological functioning have been inconsistent with some studies reporting that college students with ADHD perform more poorly on various cognitive and neuropsychological tasks while others report no differences compared to their peers without ADHD. METHOD: The purposes of the present study, the Trajectories Related to ADHD in College project, a longitudinal study following the 4-year outcomes of college students with and without ADHD, were to (a) examine the performance of 436 first-year college students with and without ADHD (51.6% female) on measures of executive function (EF) and intelligence and (b) investigate the association of self-reported use of stimulant medication and neuropsychological performance in students with ADHD. Participant data from their first year of involvement in the study were analyzed. RESULTS: Participants with ADHD performed more poorly on task-based and self-report EF measures relative to the comparison group. In contrast, no significant group differences were found with respect to intellectual performance. Within the ADHD group, use of prescription stimulant medication was associated with improved performance on some, but not all, neuropsychological tasks. Additional analyses also revealed significant group differences in EF based on clinical diagnostic status. CONCLUSION: College students with ADHD demonstrated poorer EF than their peers without ADHD and psychostimulant medication was associated with improved EF performance. No group differences were found with respect to intellectual functioning, Lastly, having one or more comorbid psychiatric diagnoses in addition to ADHD was associated with poorer EF outcomes.

Prescription stimulant medication misuse: Where are we and where do we go from here?

Prescription stimulants, including methylphenidate (e.g., Ritalin) and amphetamine compounds (e.g., dextroamphetamine; Adderall), have been approved by the U.S. Food and Drug Administration for the treatment of attention-deficit/hyperactivity disorder (ADHD) and are classified by the United States Drug Enforcement Administration as Schedule II medications because of their high potential for abuse and dependence (Drug Enforcement Administration, U.S. Department of Justice, 2015). Despite the potential health and judicial consequences, misuse of prescription stimulants, typically defined as taking stimulants without a valid prescription, or use of stimulants other than as prescribed, has become a serious problem in the United States and abroad, especially on college campuses. The purpose of the present article is to review historical information concerning prescription stimulants and to summarize the literature with respect to misuse among adults, particularly college students, including risk factors, mediators and moderators, and motivations for prescription stimulant misuse. In addition, evidence is presented concerning the question of whether prescription stimulants truly enhance cognitive functioning in individuals with and without ADHD, and the ethical and professional implications of these findings are explored. Lastly, recommendations for addressing prescription stimulant misuse and suggestions for future research are advanced. (PsycINFO Database Record

Pharmacological interventions for adolescents and adults with ADHD: stimulant and nonstimulant medications and misuse of prescription stimulants.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity that cause functional impairment. Recent research indicates that symptoms persist into adulthood in the majority of cases, with prevalence estimates of approximately 5% in the school age population and 2.5%-4% in the adult population. Although students with ADHD are at greater risk for academic underachievement and psychosocial problems, increasing numbers of students with ADHD are graduating from high school and pursuing higher education. Stimulant medications are considered the first line of pharmacotherapy for individuals with ADHD, including college students. Although preliminary evidence indicates that prescription stimulants are safe and effective for college students with ADHD when used as prescribed, very few controlled studies have been conducted concerning the efficacy of prescription stimulants with college students. In addition, misuse of prescription stimulants has become a serious problem on college campuses across the US and has been recently documented in other countries as well. The purpose of the present systematic review was to investigate the efficacy of prescription stimulants for adolescents and young adults with ADHD and the nonmedical use and misuse of prescription stimulants. Results revealed that both prostimulant and stimulant medications, including lisdexamfetamine dimesylate, methylphenidate, amphetamines, and mixed-amphetamine salts, are effective at reducing ADHD symptoms in adolescents and adults with ADHD. Findings also suggest that individuals with ADHD may have higher rates of stimulant misuse than individuals without the disorder, and characteristics such as sex, race, use of illicit drugs, and academic performance are associated with misuse of stimulant medications. Results also indicate that individuals both with and without ADHD are more likely to misuse short-acting agents than long-acting agents. These findings have implications for intervention, prevention, and future research.
