- Abstract
Monitoring the Future (MTF) is designed to give such attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with, and is conducted by, a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been funded continuously by the National Institute on Drug Abuse--one of the National Institutes of Health--under a series of peer reviewed, competitive research grants. The 2022 survey, reported here, is the 48th consecutive national survey of 12th grade students and the 32nd national survey of 8th and 10th grade students (who were added to the study in 1991). MTF contains ongoing national surveys of both adolescents and adults in the United States. It provides the nation with a vital window into the important but often hidden problem behaviors of use of illegal drugs, alcohol, tobacco, and psychotherapeutic drugs (used without a doctor's orders). For more than four decades, MTF has helped provide a clearer view of the changing topography of these problems among adolescents and adults, a better understanding of the dynamics of factors that drive some of these problems, and a better understanding of some of their consequences. It has also given policymakers, government agencies, and nongovernmental organizations (NGOs) in the field some practical approaches for intervening. Two of the major topics included in the present monograph are: (1) the prevalence and frequency of use of a great many substances, both licit and illicit, among U.S. secondary school students in 8th, 10th, and 12th grades; and (2) historical trends in use by students in those grades. Distinctions are made among important demographic subgroups in these populations based on gender, college plans, region of the country, population density, parent education, and race/ethnicity. MTF has demonstrated that key attitudes and beliefs about drug use are important determinants of usage trends, in particular the amount of risk to the user perceived to be associated with the various drugs and disapproval of using them; thus, those measures also are tracked over time, as are students' perceptions of certain relevant aspects of the social environment--in particular, perceived availability of each drug, peer norms about their use, use by friends, and exposure to use by others of the various drugs. Data on grade of first use, noncontinuation of use, trends in use in lower grades (based on retrospective reports), and intensity of use are also reported here.

- Abstract
Objective: We appraised whether FDA registration trials for ADHD pharmacotherapy in adults provides comparable information to inform treatment expectations. Method: Comparison of ADHD outcome measure patterns in ADHD pharmacotherapy FDA drug label source studies. Results: Among stimulants, from fixed-dose titration data, amphetamine agents had numerically higher placebo-corrected symptom improvement and symptom effect sizes than methylphenidate agents. Symptom effect sizes were lower in the flexible dosing registration studies of atomoxetine and viloxazine. Varying responder definitions were analyzable, based on [greater than or equal to] 30% symptom improvement and/or CGI-I improvement of "much" or "very much improved." Number of exposures needed to create these responses were lower for stimulants than for viloxazine. Conclusion: Heterogeneity in the design and analysis of FDA drug label source trials restricts implications for clinical practice. Research conducted using replicated designs, direct comparison of available treatments, and outcome analyses that generalize to clinical care could better inform clinical decision making.

- Abstract
Objective: To examine the effects of triple beaded mixed amphetamine salts (TB MAS) on ADHD and executive dysfunction symptoms throughout the day in adults with DSM-5 ADHD. Method: This was a 6 week, single-blind, placebo-lead in trial of TB MAS (12.5-37.5 mg/day); all participants received 2 weeks of single-blind placebo); one individual was a placebo responder and was discontinued. One of these 18 dropped after 1 week on 12.5 mg/day, while all others completed the trial and received 37.5 mg/day TB MAS. Results: There were significant effects of TB MAS on all clinical measures, including investigator overall symptoms (AISRS); self-report overall (ASRS), time-sensitive ADHD (TASS) scores throughout the day, impairment (CGI) and executive function scores (BRIEF-A). TB MAS was generally well tolerated. Conclusions: This study extends prior findings of TB MAS to adults with DSM-5 ADHD; it further re-validates findings of efficacy of TB MAS throughout the day.

Yuwen Hung, Allison Green, Caroline Kelberman, Schuyler Gaillard, James Capella, Nicole Rudberg, John D. E. Gabrieli, Joseph Biederman, and Mai Uchida
- Abstract
Objective: Stimulant medications are the main treatment for Attention Deficit Hyperactivity Disorder (ADHD), but overall treatment efficacy in adults has less than a 60% response rate. This study aimed to identify neural and cognitive markers predictive of longitudinal improvement in response to stimulant treatment in drug-naïve adults with ADHD. Method: We used diffusion tensor imaging (DTI) and executive function measures with 36 drug-naïve adult ADHD patients in a prospective study design. Results: Structural connectivity (measured by fractional anisotropy, FA) in striatal regions correlated with ADHD clinical symptom improvement following stimulant treatment (amphetamine or methylphenidate) in better medication responders. A significant positive correlation was also found between working memory performance and stimulant-related symptom improvement. Higher pre-treatment working memory scores correlated with greater response. Conclusion: These findings provide evidence of pre-treatment neural and behavioral markers predictive of longitudinal treatment response to stimulant medications in adults with ADHD. (J. of Att. Dis. 2024; 28(5) 936-944)

- Abstract
Background: Research examining the potential effects of stimulant exposure in childhood on subsequent development of substance use disorder (SUD) have focused on differences in the brain reward system as a function of risk. Methods: 18 drug naïve children ages 7 to 12 years (11 High Risk [ADHD + ODD/CD]; 7 Low Risk [ADHD only]), underwent fMRI scans before and after treatment with mixed amphetamine salts, extended release (MAS-XR). We examined correlations between clinical ratings and fMRI activation at baseline and following treatment as a function of risk status. Results: High Risk children had higher activation than Low Risk children at baseline during both the Reward and Surprising Non-Reward conditions. Treatment produced strong differential effects on brain activation pertinent to group and reward outcome. Conclusions: Findings support the hypothesized role of reward mechanisms in SUD risk, and suggest that stimulant treatment may have differential effects on reward processing in relation to SUD risk.

- Abstract
Monitoring the Future (MTF) is an ongoing research program conducted at the University of Michigan's Institute for Social Research under a series of investigator-initiated, competing research grants from the National Institute on Drug Abuse beginning in 1975. The integrated MTF study includes annual surveys of nationally representative samples of 8th, 10th, and 12th grade students, as well as a subset of 12th grade students followed into adulthood from each graduating class. Repeating these annual cross-sectional surveys over time provides data to examine behavior change across history in consistent age segments of the adult population, as well as among key subgroups. The panel study now has over 110,000 individuals, with approximately 28,500 surveyed each year including young adults ages 19 to 30 and midlife adults ages 35 to 60. These data, gathered on national samples over such a large portion of the lifespan, are extremely rare and can provide needed insight into the epidemiology, etiology, and life course history of substance use and relevant behaviors, attitudes, and other factors. The current report is the latest in a series of publications dating back to 1986 and updated annually since then, all available at monitoringthefuture.org.

- Abstract
Monitoring the Future (MTF) has become one of the nation's most relied upon scientific sources of valid information on trends in use of licit and illicit psychoactive drugs by U.S. adolescents, college students, young adults, and adults up to age 60. During the last four decades, the study has tracked and reported on the use of an ever-growing array of such substances in these populations of adolescents and adults. The annual MTF series of monographs is one of the primary mechanisms through which the new epidemiological findings are reported. Findings from the inception of the study in 1975 through 2022 are included--the results of 48 national in-school surveys and 46 national follow up surveys. MTF has conducted in-school surveys of nationally representative samples of: (1) 12th grade students each year since 1975; and (2) 8th and 10th grade students each year since 1991. In addition, beginning with the class of 1976, the study has conducted follow up surveys of representative subsamples of the respondents from each previously participating 12th grade class. These follow up surveys now continue well into adulthood, currently up to age 60. MTF is designed to detect age, period, and cohort effects in substance use and related attitudes. Age effects are similar changes at similar ages seen across multiple class cohorts; they are common during adolescence. Period effects are changes that are parallel over a number of years across multiple age groups (in this case, all three grades under study--8, 10, and 12). Cohort effects are substance use behaviors or attitudes that distinguish a class cohort from others that came before or after them and are maintained as the cohort ages. The survey results divide cleanly into the time periods before and after the onset of the COVID-19 pandemic. All surveys in 2020 were completed before March 15, when data collection was halted due to pandemic concerns. Consequently, results from 2020 and previous years are pre-pandemic, while results from 2021 and 2022 took place after the onset of the pandemic and the associated national response.

- Abstract
Medication for attention-deficit/hyperactivity disorder (ADHD) is frequently abused and misused alongside alcohol on college campuses. The aim of the study was to assess the relationship between participants' alcohol use, mental distress, and academic performance in relation to their illicit use of ADHD medication. An anonymous cross-sectional survey administered online using Google Forms compiled 702 U.S. college students' responses evaluating their drug usage, academic performance, and mental health. ADHD medication use had a positive association (p < 0.05) (p < 0.01) with hallmarks of mental distress and perceived stress. There was a negative association (p < 0.05) (p < 0.01) between alcohol use in the last 12 months and feelings of mental distress and perceived stress. There were negative associations (p < 0.05) (p < 0.01) found between illicit ADHD medication use and hallmarks of GPA. A positive association (p < 0.05) was also found between alcohol use in the last 4 weeks and students' positive perceptions of the effectiveness of illicit ADHD medication. These findings on the relationships between illicit usage of ADHD medication and usage of alcohol as it relates to mental health are important in broadening our understanding of some of the most important risk factors that illicit use of ADHD medication and alcohol usage can have on college students.

- Abstract
Objective: This study determined the frequency, reasons for, and side effects of energy drinks (ED) consumption among online students. Participants: Students attending an online university. Methods: Participants were recruited by email and completed a 59-question survey about their prior months ED practices using a combination of validated surveys previously published examining similar constructs in on-campus students. Results: 307 students (age = 32.4 ± 6.5yrs) completed the survey, and 88% reported consuming EDs. Students' reasons for consuming ED included school (p < 0.001), work (p < 0.001), an event/competition (p < 0.001), pick me up (p < 0.001), lack of rest (p < 0.001), more energy (p < 0.001), and staying awake while driving (p < 0.001). Only individuals who consumed >10 ED/month reported side effects of headaches (p = 0.01) and speeding (p = 0.01). Conclusions: In our sample, a majority of the participants reported consuming ED for various daily activities. Only frequent consumers reported side effects suggesting they had become habituated to caffeine since they drank EDs despite experiencing side effects.

- Abstract
Objective: To compare physical activity (PA), sitting time, and substance use pre-COVID-19 and during COVID-19 pandemic among US college students. Participants: 484 students from a large Western university (20.6 ± 1.4 years, 80.0% female) were recruited. Methods: Self-reported online surveys were completed in June-August 2020. T-tests and non-parametric analyses were conducted for continuous and ordinal variables respectively. Results: Vigorous PA, moderate PA, and light PA decreased significantly by 32%, 27%, and 21% and sitting time increased significantly by 49% from pre-COVID-19 to during COVID-19 pandemic. Wine consumption was less during COVID-19 than pre-COVID-19 among female, non-first-generation, and White students. Sleep aids use was more frequent during COVID-19 than pre-COVID-19 pandemic among non-first-generation and White students. Conclusion: COVID-19 pandemic may influence college students' health behaviors including physical activity patterns, sitting time, and substance use. Effective health promotion and coping strategies should be widely available to college students during times of change and uncertainty.

Jarim Kim
- Abstract
Objective: This study investigated the factors that impact the effectiveness of energy drink-related health messages. Specifically, this study examined how behavioral status moderates the effects of the temporal contexts described in messages related to energy drink consumption. Participants: A total of 823 college students enrolled in a northeastern university participated in this study. Methods: A 2 (temporal context: proximate vs. distant) × 3 (behavioral status: non-initiator vs. former consumer vs. current consumer) experiment was conducted. Results: Proximate context messages were more effective for non-initiators and current consumers in influencing descriptive norms and attitudes respectively, whereas distant context messages were marginally more effective for former consumers in influencing descriptive norms. Conclusion: The findings contribute to health promotion research by advancing scholarly understanding of the various behavioral status-dependent psychological effects of temporal context. Moreover, the results have implications for designing effective health campaign messages targeted to college students.

- Abstract
Objective: Despite community colleges accounting for 34% of all undergraduate enrollment, research on substance-use patterns among community college students is limited. Community college students may engage in substance use differently than their 4-year university counterparts due to differences in psychosocial factors and decreased availability of mental health services. The current study aimed to elucidate risk factors underlying non-medical use of prescription simulants (NMUS) and nicotine use by community college students. Methods: A web-based survey was administered to 10 of 13 community colleges within a southeastern state's Board of Regents school system. The survey included questions related to NMUS, nicotine use, alcohol use, mental health diagnosis, and demographics. Results: Overall, 9% of the participants reported NMUS, and 24.6% used nicotine. Multivariate analysis of variance and ?[subscript 2] tests revealed group differences among individuals using only nicotine, only NMUS, both nicotine and NMUS, and neither nicotine nor NMUS. Post-hoc 2 × 2 ?[subscript 2] tests indicated that individuals using both nicotine and NMUS had higher incidence of mental health diagnoses, were more likely to live in urban areas, reported higher weekly alcohol consumption, and were more likely to be male as compared to individuals using neither substance. Attention-deficit hyperactivity disorder (ADHD) symptoms were higher in individuals using only NMUS and both NMUS and nicotine as compared to those using only nicotine or neither substance. Conclusions: These findings provide insight into demographic and psychological variables associated with NMUS and nicotine use among community college students that could be benefitted by greater access to affordable mental health services.

- Abstract
Background: Research has been inconclusive as to whether stimulant treatment causes or exacerbates sleep problems in adolescents with ADHD. This study examined sleep differences in adolescents with ADHD as a function of stimulant use. Methods: Participants were adolescents with ADHD (N=159, ages 12-14). Parents reported on receipt of stimulant treatment (n=92, 57.86%; n=47 amphetamines, n=45 methylphenidate). Adolescents wore actigraphs and completed daily diaries assessing sleep and daily use of stimulants for two weeks. Sleep parameters included daily-reported bedtime, sleep onset latency (SOL), sleep duration, daytime sleepiness, and difficulty waking the following morning; and actigraphy-measured sleep onset time, total time in bed, and sleep efficiency. We estimated between- and within-individual associations between stimulant medication use and sleep indices with all stimulants, after removing adolescents using sleep aids and weekend days, and as a function of stimulant type. Results: Adolescent sleep did not differ between those receiving and not receiving stimulant treatment. Within individuals using stimulants, we largely observed no significant differences between medicated and unmedicated days, though findings were most often significant for school days only. Small effects were found indicating longer SOL, later sleep onset time, and more daytime sleepiness related to medication use. In contrast, there were slight improvements to sleep duration and sleep efficiency related to methylphenidate use, though methylphenidate was also associated with later sleep onset time and more daytime sleepiness. Conclusions: Given the inconsistent and small effects, findings suggest that stimulant medication may impact sleep, but does not appear to be a primary contributor to sleep problems in adolescents with ADHD.

- Abstract
This study aimed to examine the relationship between the caffeine consumption status of students in sports sciences and their happiness levels. The study was quantitative and was conducted with the participation of 228 volunteer students studying in sports sciences from various universities (Artvin Coruh, Trabzon, Bayburt, Igdir, Agri Ibrahim Çeçen, Gazi, Atatürk). The Oxford Happiness Scale (OHS) developed by (Hills & Argyle, 2002) and this questionnaire were used to collect the data. Statistical analysis of the data was performed with independent groups T-test, one-way analysis of variance (ANOVA) and Pearson correlation analysis. As a result of the analysis, while a positive and low-level significant relationship was found between the students' happiness scores and the age variable (p < 0.05); no significant difference was found in the variables of gender, body mass index (BMI), department of education (p > 0.05). When looking at the variable of doing sports, statistically significant differences were found, and it was concluded that the mean score of those who did sports as licensed-national was significantly higher than the mean score of those who did sports as hobbyists and amateurs (p < 0.05). Again, a statistically significant difference was found in happiness scores according to chronic disease states; (p < 0.05) no difference was found according to smoking status (p > 0.05). At the same time, a statistically positive and low-level significant relationship was found between happiness scores and the amount of coffee consumed daily (p < 0.05); No statistically significant relationship was found between happiness and the amount of black tea and chocolate consumed daily (p > 0.05).

This volume presents new 2021 findings from the U.S. national Monitoring the Future follow-up (panel) study concerning substance use among the nation's college students and adults from ages 19 through 60. We report 2021 prevalence estimates on numerous illicit and licit substances, examine how substance use differs across this age span, and show how substance use and related behaviors and attitudes have changed over the past four decades. The panel study now has over 108,000 individuals, with approximately 28,500 surveyed each year including young adults ages 19 to 30 and adults ages 35 to 60. These data, gathered on national samples over such a large portion the lifespan, are extremely rare and can provide needed insight into the epidemiology, etiology, and life course history of substance use and relevant behaviors, attitudes, and other factors. The current report is the latest in a series of publications dating back to 1986.

- Abstract
This occasional paper presents national demographic subgroup data for the 1975-2021 Monitoring the Future (MTF) national survey results on 8th, 10th, and 12th graders' use of drugs, alcohol, and tobacco. The study covers all major classes of illicit and licit psychoactive drugs for an array of population subgroups. The 2020 subgroup data presented here accompany the "Monitoring the Future National Survey Results on Drug Use: 1975-2021: Overview, Key Findings on Adolescent Drug Use" (see ED618240) and the "Monitoring the Future National Survey Results on Drug Use, 1975-2021, forthcoming: Volume I, Secondary School Students." The trends offered here in tabular and graphic forms cover demographic subgroups based on: (1) Gender; (2) College plans; (3) Region of the country; (4) Population density; (5) Education level of the parents (a proxy for socioeconomic level); and (6) Racial/ethnic identification. Detailed descriptions of the demographic categories are provided in the section starting on page 469 of this paper. The graphs and tables in this occasional paper present trend data for 8th-, 10th-, and 12th-grade respondents separately. Data for 12th grade begins with 1975, the first year in which a nationally representative sample of high school seniors was surveyed. Data for 8th and 10th grades begin with 1991, when the study's nationally representative annual surveys were expanded to include surveys of those lower grade levels.

- Abstract
Monitoring the Future (MTF) is a long term study of substance use and related factors among U.S. adolescents, college students, and adult high school graduates through age 60. It is conducted annually and supported by the National Institute on Drug Abuse. MTF findings identify emerging substance use problems, track substance use trends, are published with many scientific results, and help to inform policy and intervention strategies. The key findings regarding use of various substances by 8th, 10th, and 12th graders surveyed across the U.S. in 2021 are summarized below. But first a few words about the context. The preceding year, 2020, was an unusual year for the study in that data collection was halted earlier than usual, in March of that year, due to the emerging COVID-19 epidemic and the University of Michigan halting in-person research. This resulted in smaller samples being obtained that year, but based on careful analyses we believe that the smaller samples reflect drug use for all students that year with reasonable accuracy. The previous year, 2019, was unusual in a different way--it was the year that the study was transitioning from using paper and pencil questionnaires in schools to having students use electronic tablets. A random half of all respondents in 2019 used the older mode of administration, while the other half used tablets. How the authors e dealt with these two disruptions to the ongoing series is described in the section on Study Design and Methods. It should be noted that the 2020 data collection occurred early in 2020, covering the early months of the epidemic, but it did not cover most of the period of the epidemic that year, nor of its effects. However, the 2021 data collection occurred more than a year into the COVID epidemic and brought quite dramatic changes in adolescent drug use in the United States. A synopsis of the design and methods used in the study follows the introductory section. A separate section is then provided for each individual drug class, including figures that show trends in the overall proportions of students at each grade level (1) using the drug; (2) seeing a "great risk" associated with its use (perceived risk); (3) disapproving of its use (disapproval); and (4) saying that it would be "fairly easy" or "very easy" to get if they wanted to (perceived availability). For 12th graders, annual data are available since 1975--and for 8th and 10th graders since 1991, the first year they were included in the study. The tables at the end of this report provide the statistics underlying the figures; in addition, they present trend data on lifetime, annual, 30 day, and (for selected drugs) daily prevalence.

- Abstract
The present volume presents new 2020 findings from the U.S. national Monitoring the Future (MTF) follow-up study concerning substance use among the nation's college students and adults from ages 19 through 60. This volume reports 2020 prevalence estimates on numerous illicit and licit substances, examines how substance use differs across this age span, and shows how substance use and related behaviors and attitudes have changed over the past four decades. The 2020 panel data collections occurred during the start of the COVID-19 pandemic (from March 2020 through November 2020), and this volume constitutes one of the first considerations of possible pandemic effects on prevalence and trends of substance use among the MTF young and middle-aged adults. This volume reports the results of the repeated cross-sectional surveys of all high school graduating classes since 1976 as they are followed into their adult years. Segments of the general adult population represented in these follow-up surveys include: (1) U.S. college students; (2) same-aged youth who also are graduates from high school but not attending college full time, sometimes in the past called the "forgotten half,"; (3) all young adult high school graduates of modal ages 19 to 30, called the "young adult" sample; and (4) high school graduates at the specific later modal ages of 35, 40, 45, 50, 55, and 60. This volume emphasizes historical and developmental changes in substance use and related attitudes and beliefs occurring at these age strata.

- Abstract
Monitoring the Future (MTF) is designed to give attention to substance use among the nation's youth and adults. Since its onset in 1975, MTF has been funded continuously by the National Institute on Drug Abuse -- one of the National Institutes of Health -- under a series of peer-reviewed, competitive research grants. The 2020 survey, reported here, is the 46th consecutive survey of 12th grade students and the 30th such survey of 8th and 10th graders. MTF contains ongoing national surveys of both adolescents and adults in the United States. It provides the nation with a vital window into the important but often hidden problem behaviors of use of illegal drugs, alcohol, tobacco, and psychotherapeutic drugs (not under a doctor's orders). For more than four decades, MTF has helped provide a clearer view of the changing topography of these problems among adolescents and adults, a better understanding of the dynamics of factors that drive some of these problems, and a better understanding of some of their consequences. It has also given policymakers, government agencies, and nongovernmental organizations (NGOs) in the field some practical approaches for intervening. Two of the major topics included in the present volume are: (1) the "prevalence and frequency" of use of a great many substances, both licit and illicit, among U.S. secondary school students in 8th, 10th, and 12th grades; and (2) "historical trends" in use by students in those grades. Distinctions are made among important demographic subgroups in these populations based on gender, college plans, region of the country, population density, parent education, and race/ethnicity. MTF has demonstrated that key attitudes and beliefs about drug use are important determinants of usage trends, in particular the amount of risk to the user perceived to be associated with the various drugs and disapproval of using them; thus, those measures also are tracked over time, as are students' perceptions of certain relevant aspects of the social environment -- in particular, perceived availability, peer norms, use by friends, and exposure to use by others of the various drugs. Data on grade of first use, discontinuation of use, trends in use in lower grades, and intensity of use are also reported here.

Maloney, Erin K., Bleakley, Amy, Stevens, Robin, Ellithorpe, Morgan, and Jordan, Amy
- Abstract
Background: In the USA, lower income minority ethnic children and teenagers report high consumption of sugar sweetened beverages, which cause dental erosion and dental carries, and play a significant role in overweight, obesity and diabetes. Objective: This study aimed to examine urban adolescents' beliefs about sports and energy drinks to identify factors for health messaging to discourage youth consumption. Design: Focus group study involves 34 adolescents in urban areas (12 women, 12 men and 10 unreported sex; 19 Hispanic, 11 non-Hispanic Black, 2 Asian and 2 unknown race or ethnicity). Setting: Four focus groups were conducted with adolescents in urban areas. Method: Each on-time moderated group discussion was structured to generate an inventory of attitudinal, normative and efficacy beliefs associated with sports and energy drink consumption and reduction. Thematic analysis was used to analyse the data. Results: Attitudinal and normative beliefs were more positive towards sports drink consumption and energy drink reduction. Misperceptions about the need for sports drinks to avoid dehydration during physical activity were evident. Product accessibility and advertising pervasiveness were facilitators influencing consumption and barriers to reduction for both products. Conclusion: Results highlight important differences in perceptions about sports and energy drinks that indicate the need for different approaches and messages for interventions designed to curb consumption of these products. Recommendations for message design are provided.

- Abstract
Monitoring the Future (MTF) is a long-term study of substance use and related factors among U.S. adolescents, college students, and adult high school graduates through age 60. It is conducted annually and supported by the National Institute on Drug Abuse. MTF findings identify emerging substance use problems, track substance use trends, publish many scientific findings, and help to inform policy and intervention strategies. The key findings regarding use of various substances by 8th, 10th, and 12th graders surveyed across the coterminous U.S. in 2020 are summarized. The year 2020 was an unusual year for the study in that data collection was halted earlier than usual, in March of that year, as a result of the emerging COVID-19 epidemic. This resulted in smaller samples being obtained that year. How the authors dealt with this disruption (as well as the disruption that occurred in the 2019 study, the transition from students using paper and pencil questionnaires to using electronic tablets) to the ongoing series is described. It should be noted that the 2020 data collection occurred early in 2020, so it does not cover most of the period of the pandemic, nor of its effects.

- Abstract
This occasional paper presents subgroup findings from the Monitoring the Future (MTF) study on levels of, and trends in, the use of a number of substances for nationally representative samples of high school graduates ages 19-30, "Monitoring the Future National Survey Results on Drug Use, 1975-2018. Volume II, College Students & Adults Ages 19-60" (see ED599071). The data have been gathered in a series of follow-up surveys of representative subsamples of high school seniors who were first surveyed in 12th grade as part of the MTF study. Data were first available for the 19-22 age group in 1980 and for the older age groups in subsequent years as the early cohorts progressed in age, as the tables and figures in this occasional paper indicate. The subgroup trends shown in the current occasional paper complement the last section of Chapter 5 (Trends in Drug Use in Early and Middle Adulthood) of that monograph by presenting the trend data for young adult subgroups in both graphic and tabular form. The results are described and discussed in Chapter 5, but the extensive set of tables and figures is provided here for the reader who wishes to view the figures and the underlying numerical values in tabular form. Three demographic dimensions are differentiated: gender, region of the country, and population density. Gender includes trends for males and females; region describes trends for each of the four major regions defined by the U.S. Census; and population density differentiates trends for five levels of community size. The Table of Contents and List of Figures in this occasional paper contain links to the content and figures. Following each figure is a table giving the numerical values associated with each trend line in that figure. [For the 1988-2019 Monitoring the Future Occasional Paper, see ED608244.]

- Abstract
This study explored college student's perceptions and attitudes towards stimulant misuse. Participants were presented with vignettes describing stimulant misuse and were asked to rate their perceptions of dangerous behavior, academic dishonesty and other similar areas. They then completed scales assessing their past alcohol and drug use, attitudes towards substance use, and attitudes towards academic dishonesty. Results showed that participants who had engaged in past drug use viewed the vignettes as containing less dangerous behavior, results also indicated that vignettes describing more severe stimulant misuse as more indicative of a substance use problem. The implications of these results suggest that college students' past behavior and attitudes impact their perceptions of stimulant misuse.

- Abstract
Objective: College students' prescription stimulant and opioid misuse (PSM and POM) share psychosocial risks with other substance use. We sought to extend a prior study of these issues. Methods: National College Health Assessment (2015-2016) participants ages 18-24 years (n = 79,336) reporting 12-month PSM (defined as use of a drug not prescribed to them), 30-day other illicit drug use (non-cannabis), both, or neither, were compared on other substance use, psychopathology, academic adjustment, attention deficit hyperactivity disorder, and chronic pain. Models were repeated for POM. Results: Relative to those who only misused the prescription drug, those who used other illicit drugs had lower odds of chronic pain and academic problems, but higher odds on nearly every other outcome especially if they also misused the prescription drug. Conclusions: Findings suggest PSM and POM are on a continuum of risk shared with illicit drug use, but also are linked to outcomes specific to these drugs' perceived medical purposes.

Warnock, Charles Ashley, Lauckner, Carolyn L., and Ingram, Lucy A.
- Abstract
Objective: To explore the relationship between past 30-day nonmedical prescription stimulant use (NPSU) and past 30-day marijuana and/or alcohol use, past 30-day risky marijuana and/or alcohol use, student demographics, and student activity involvement among college students. Participants: Sample of 604 college-aged students at two large universities in the southeastern U.S. Methods: A cross-sectional survey was completed electronically. Logistic regression was used to identify and test covariates of past 30-day NPSU. Results: Over 20% of participants self-reported past NPSU. Using both marijuana and alcohol in the past 30 days ([beta] = 3.293, p = 0.002, OR= 26.91, 95% CI OR= 3.42, 211.92) and engaging in both risky marijuana and alcohol use ([beta] = 2.095, p < 0.001, OR = 8.13, 95% CI OR = 2.52, 25.17) were significantly related to past 30-day NPSU. Conclusions: NPSU may be indicative of broader polysubstance use problems among college-aged students.

Summit, Alynna G. and Noel, Nora E.
- Abstract
Introduction: Two prominent motivation categories of college student nonmedical prescription stimulant use (NMUPS) are for academic and recreational purposes. However, little research focuses on these motivations' association with college students' NMUPS views. Further, limited research assesses if user gender influences views. Methods: The current online scenario study implemented a 2 × 2 factorial design assessing 148 college undergraduates' (75% females; M[subscript age] = 19.18; SD[subscript age] = 1.30) NMUPS views based on user motivation and gender. Participants reported their drug use stigmatization, prescription stimulant expectancies (ie, anticipated drug use beliefs and outcomes), and personal substance use. Results and Discussion: Results showed that user gender did not influence participants' NMUPS views; however, participants viewed academic use less negatively compared to recreational use, thus highlighting the need to educate students on the negative consequences of NMUPS, even when use is for academically related tasks. Furthermore, exploratory analyses showed drug use stigmatization and prescription stimulant expectancies predicted participant NMUPS views.

- Abstract
Research on stimulant misuse among students has been rising. These medicines are generally prescribed to treat ADHD, but they are also used by students to enhance their academic performance. To date, qualitative research on the topic is limited, specifically in understanding the "process" of misuse, i.e. the motivations embedded in a particular academic and social context driving students' decision to use. The aim of this research was to develop subtypes by disentangling patterns in the process of stimulant misuse. We conducted a focus group (n = 5) and semi-structured interviews (n = 28) with Flemish university students who had misused stimulants during their academic career. We employed abductive analysis principles, in which we build on Conrad's medicalization and enhancement theory and Cox and Klinger's motivational model of alcohol use. Two dimensions were key in differentiating theoretically meaningful subtypes: (1) perception of academic need and (2) frequency of use. The "normalization subtype" indicates having concentration problems and structurally uses stimulants to deal with these problems; the "rescue subtype" is able to study without stimulants, but occasionally uses them to cope with academic demands and/or personal stressors; the "experimental subtype" does not have an academic need to use stimulants, but temporarily uses them out of curiosity; the "performance subtype" does not need the medication, but perceives it as a convenient tool to structurally facilitate academic life, e.g. to shorten the study process. Our study shows a nuanced story of students' stimulant misuse and helps inform the development of tailored preventive measures.

- Abstract
The present volume presents new 2019 findings from the U.S. national Monitoring the Future (MTF) follow-up study concerning substance use among the nation's college students and adults from ages 19 through 60. This report includes 2019 prevalence estimates on numerous illicit and licit substances, examines how substance use differs across this age span, and shows how substance use and related behaviors and attitudes have changed over the past four decades. MTF, now in its 46th year, is a research program conducted at the University of Michigan's Institute for Social Research under a series of investigator-initiated, competing research grants from the National Institute on Drug Abuse -- one of the National Institutes of Health. The integrated MTF study comprises several ongoing series of annual surveys of nationally representative samples of 8th and 10th grade students (begun in 1991), 12th grade students (begun in 1975), and high school graduates followed into adulthood (begun in 1976). Note that the data reported in this volume were collected before the COVID-19 pandemic. The authors report the results of the repeated cross-sectional surveys of all high school graduating classes since 1976 and follow them into their adult years. Segments of the general adult population represented in these follow-up surveys include: (1) U.S. college students; (2) same-aged youth who also are graduates from high school but not attending college full time, sometimes in the past called the "forgotten half"; (3) all young adult high school graduates of modal ages 19 to 30 (or 19-28 for trend estimates), to whom we refer as the "young adult" sample; and (4) high school graduates at the specific later modal ages of 35, 40, 45, 50, 55, and 60. This volume emphasizes historical and developmental changes in substance use and related attitudes and beliefs occurring at these age strata.

- Abstract
Substance use is a leading cause of preventable morbidity and mortality; it is in large part why, among 17 high-income nations, people in the U.S. have the highest probability of dying by age 50. Substance use is also an important contributor to many social ills including child and spousal abuse, violence more generally, theft, suicide, and more; and it typically is initiated during adolescence. It warrants our sustained attention. Monitoring the Future (MTF) is designed to give such attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with, and is conducted by, a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been funded continuously by the National Institute on Drug Abuse -- one of the National Institutes of Health -- under a series of peer-reviewed, competitive research grants. The 2019 survey, reported here, is the 45th consecutive survey of 12th grade students and the 29th such survey of 8th and 10th graders. Two of the major topics included in the present volume are: (1) the prevalence and frequency of use of a great many substances, both licit and illicit, among U.S. secondary school students in 8th , 10th, and 12th grades; and (2) historical trends in use by students in those grades. Distinctions are made among important demographic subgroups in these populations based on gender, college plans, region of the country, population density, parent education, and race/ethnicity. MTF has demonstrated that key attitudes and beliefs about drug use are important determinants of usage trends, in particular the amount of risk to the user perceived to be associated with the various drugs and disapproval of using them; thus, those measures also are tracked over time, as are students' perceptions of certain relevant aspects of the social environment--in particular, perceived availability, peer norms, use by friends, and exposure to use by others of the various drugs.

32. Substance Use Profiles among Gang-Involved Youth: Social Ecology Implications for Service Approaches

Bishop, Asia S., Fleming, Christopher M., and Nurius, Paula S.
- Abstract
Substance use is a frequently cited health risk behavior in the youth gang literature, yet little is known about how substance use patterns vary among gang-involved youth or the social ecological factors that contribute to potential variation. Developing relevant and effective service approaches will require an understanding of this variation and the malleable factors that are likely to promote or inhibit particular patterns of use. Using latent class analysis, we identified four substance use classes within a school-based sample of gang-involved youth (n = 2,770): Non-Users (38%), Past Users (15%), Casual Users (27%), and Frequent Multi-Users (21%). These classes were distinguished by substance type, frequency of use, and source of access. Demographic and substance use-specific ecological factors across the family, peer, school, and neighborhood contexts were found to significantly differentiate these classes. Specifically, acceptance of use by parents, friends, and neighbors, along with a lack of family rules and high accessibility in the neighborhood, significantly differentiated use patterns. Findings highlight the need for service approaches that are responsive to the unique needs of individuals and their environments. Implications for practice are discussed, including the potential utility of applying a harm reduction service framework to address youth gang substance use.

- Abstract
This occasional paper presents national demographic subgroup data for the 1975-2019 Monitoring the Future (MTF) national survey results on 8th, 10th, and 12th graders' use of drugs, alcohol, and tobacco. The 2018 subgroup data presented in this report accompany the "Monitoring the Future National Survey Results on Drug Use: 1975-2019: Overview, Key Findings on Adolescent Drug Use" (see ED604018) and the "Monitoring the Future National Survey Results on Drug Use, 1975-2018: Volume I, Secondary School Students" (see ED599067). The trends presented in this occasional paper in tabular and graphic forms cover demographic subgroups based on: (1) Gender; (2) College plans; (3) Region of the country; (4) Population density; (5) Education level of the parents (a proxy for socioeconomic level); and (6) Racial/ethnic identification. Detailed descriptions of the demographic categories are provided. The graphs and tables in this occasional paper present trend data for 8th-, 10th-, and 12th-grade respondents separately. Data for 12th grade begins with 1975, the first year in which a nationally representative sample of high school seniors was surveyed. Data for 8th and 10th grades begin with 1991, when the study's nationally representative annual surveys were expanded to include those lower grade levels.

36. 'Cognitive Enhancers': A Qualitative Exploration of University Students' Experiences with Prescription Medicines for Academic Purposes

- Abstract
Qualitative work with students who use prescription medicines for academic purposes is limited. Thus, a more nuanced understanding of tertiary students' experiences is urgently needed. Our study -- which draws on five semi-structured interviews with New Zealand university students, complemented with information from local newspapers, blog entries and discussion forums -- reveals students' motivations and perceived effects, their risk perceptions and provides insights into the circumstances enabling the engagement with prescription medicines for academic purposes. Students were influenced by peers and social norms; and ideas about identity, morality and fairness also played a role for engaging with cognitive enhancers. Students used high levels of stress and workload to justify their use but took individual responsibility for their practices. By taking responsibility in this way, rather than considering it as a product of their environment, they buy into the neoliberal university discourse. Unexpectedly, some participants were already receiving medically justified psychopharmacological treatment but extended and supplemented this with nonmedical use. Others considered their use as being for academic emergencies, and that their low level of use helped manage risks. Overall, students viewed pharmacological cognitive enhancement for improving academic performance as cautious, safe, and morally acceptable. We argue in this paper that a local understanding of students' motivations, justifications and perceptions of pharmacological cognitive enhancement is required, to tailor policies and support systems better to their needs and behaviours.

- Abstract
Consumption of beverages is not considered adequate by athletes and coaches. The preliminary knowledge of those who are going to study in Sports Sciences Faculties will be very important. All participants were 1st year students. In the study, participants were asked to assess their socio-demographic characteristics and health behaviors, sport habbits, to determine energy drinks (ED), sports drinks (SD) and ergogenic substances (ES) patterns and frequency and consumption purposes, relationship between consumption status. Use a data collection form was prepared to determine the presence or absence of relevant proposals. Total of 101 participants (55 males, 19.2±1.5; 46 females, 19.0±1.2 years of age), participated in the survey to examine the attitudes of ED, SD and ES. The data were evaluated in the SPSS 21.0. The categorical variables in the questionnaire were reported as number, percentage, mean and standard deviation. A "chi-square test" and One way ANOVA tests was used. Statistical significance level was accepted as p <0,05. 52.5% of the students stated that energy drinks were beneficial, 57.4% said sports drinks were beneficial and 61.4% of the participants said that they did not have an idea about "ergogenic substances". The prevalence of ED usage was 40.0% for males and 19.5% for females (p: 0.027). While 45.4% of the males are using the SDs, this rate was found to be 13.0% in females (p<0.001). Regarding the use of ED, SD and ES, the young population and especially the sports educators in the future should be informed for the public health. As a result of this study, we would like to draw attention to the importance of education for pre-university youth. In recent years, it is important to make new educational arrangements for the developing and changing consumption habits of young people.

The data have been gathered in a series of follow-up surveys of representative subsamples of high school seniors who were first surveyed in 12th grade as part of the MTF study. Therefore, the universe being described omits people who did not complete high school--between 8 and 15% of each age group, with the most recent class cohorts closer to the bottom of that range. Surveys of the graduating cohorts of high school seniors started in 1976 and have continued with each graduating class since. Data were first available for the 19-22 age group in 1980 and for the older age groups in subsequent years, as the tables and figures in this occasional paper indicate. The general epidemiological findings from these samples are discussed in "Volume II" of the annual monograph series. The subgroup trends shown in this occasional paper complement the last section of Chapter 5 (Trends in Drug Use in Early and Middle Adulthood) of that monograph by presenting the trend data for young adult subgroups in both graphic and tabular form. The results are described and discussed in Chapter 5, but the extensive set of tables and figures is provided in this paper for the reader who wishes to view the figures and the underlying numerical values. Three demographic dimensions are differentiated: gender, region of the country, and population density. Gender includes trends for males and females; region describes trends for each of the four major regions defined by the U.S. Census; and population density differentiates trends for five levels of community size. The Table of Contents and List of Figures in this occasional paper contain links to the content and figures. Following each figure is a table giving the numerical values associated with each trend line in that figure.

- Abstract
Monitoring the Future (MTF) is a long-term study of substance use and related factors among U.S. adolescents, college students, and adult high school graduates through age 60. It is conducted annually and supported by the National Institute on Drug Abuse. MTF findings identify emerging substance use problems, track substance use trends, and inform national policy and intervention strategies. MTF is designed to detect age, period, and cohort effects in substance use and related attitudes. Age effects are similar changes with age seen across multiple class cohorts; they are common during adolescence. Period effects are changes that are parallel over a number of years across multiple age groups (in this case, all three grades under study--8, 10, and 12). Cohort effects are consistent differences among birth cohorts (or in this case, class cohorts) that are then maintained as the cohorts age. The key findings regarding use of various substances by 8th, 10th, and 12th graders surveyed across the coterminous U.S. in 2018 are presented in this report.

- Abstract
This occasional paper presents national demographic subgroup data for the 1975-2018 Monitoring the Future (MTF) national survey results on 8th, 10th, and 12th graders' use of drugs, alcohol, and tobacco. The study covers all major classes of illicit and licit psychoactive drugs for an array of population subgroups. The trends are presented in tabular and graphic forms and cover demographic subgroups based on: (1) Gender; (2) College plans; (3) Region of the country; (4) Population density; (5) Education level of the parents (a proxy for socioeconomic level); and (6) Racial/ethnic identification. Detailed descriptions of the demographic categories are provided in the section starting on page 385 of this paper. The graphs and tables in this occasional paper present trend data for 8th-, 10th-, and 12th-grade respondents separately. Data for 12th grade begins with 1975, the first year in which a nationally representative sample of high school seniors was surveyed. Data for 8th and 10th grades begin with 1991, when the study's nationally representative annual surveys were expanded to include those lower grade levels.

- Abstract
Aims: The current study aims to examine the role of energy drink and energy shot consumption in school disengagement, low academic performance, and academic expectations, and investigates the robustness of these associations across sex, grade, race, and substance use history. Method: This study employs a pooled cross-sectional design and uses a nationally representative sample of 8th (ages 13-14 years) and 10th (ages 15-16 years) grade adolescents from seven recent cohorts (2010-2016) of the Monitoring the Future study. Logistic regression and negative binomial regression were employed to examine the association between energy drink and energy shot consumption and academic risk factors, controlling for sociodemographic factors and other health and social behaviors. Ancillary robustness checks across key subgroups in the data were also performed. Results: The results indicate that energy drink and energy shot consumers are significantly more likely to report all academic risk outcomes. Specifically, youth who heavily use energy drinks and shots have significantly higher odds of each of the academic risk outcomes relative to both less habitual users and nonusers. These patterns hold across subgroups, despite associations being somewhat stronger among females, younger participants, Whites, and youth with no substance use history. Conclusions: The current study suggests that energy drink consumption (particularly heavy consumption) may be an early warning sign of academic risk. It may be beneficial to limit adolescent energy drink consumption, provide early intervention for heavy adolescent consumers, and raise awareness of the dangers associated with their use.

- Abstract
Objective: The current study examined the regular use of study strategies between college students who misused prescription stimulants (N = 36) and college students who did not misuse prescription stimulants (N = 298) in an undergraduate sample. Participants: 334 college students at a large, Midwestern university. Methods: Using logistic regression, we examined whether students who misused prescription stimulants did so to compensate for poor study strategies and/or a lack of study strategies overall. We hypothesized that regularly spacing studying, using more study strategies, and using more effective study strategies would predict lower odds of prescription stimulant misuse among students. In contrast, we hypothesized that using more ineffective study strategies would predict higher odds of prescription stimulant misuse. Results: Results indicated that a greater number of total study strategies and effective study strategies, and higher importance of school predicted higher odds of prescription stimulant misuse. Conclusions: Thus, students may not be misusing prescription stimulants as a substitute for effective studying but, rather, to augment effective study habits.

Barringer, Alexandra and Papp, Lauren M.
- Abstract
Objective: To identify academic factors pertaining to college students, calendar timing, and particular moments that are uniquely associated with elevated likelihood of prescription stimulant misuse (intentions and actual behavior) in daily life. Participants: Participants were 297 freshmen and sophomores at a large public university in the United States in 2017-2019. Methods: Participants completed survey measures during lab visits and ecological momentary assessment procedures in daily life. Hypotheses were tested using multilevel models that accounted for the nested data and demographic covariates. Results: Student, calendar-based, and momentary academic factors were uniquely associated with stimulant misuse intentions in daily life. Real-time academic events, beyond the proportion of academic events experienced, emerged as a robust predictor of misuse behavior. Within-person links between real-time momentary predictors and misuse behavior were moderated by finals week timing. Conclusions: Findings offer implications for prevention and intervention strategies for college students at risk for prescription drug misuse.

- Abstract
A within-subjects experimental design examined differences in functional near-infrared spectroscopy (fNIRS) assessment of prefrontal cortex (PFC) activation with two virtual reality (VR) drawing conditions (rote tracing and creative self-expression) with and without a fragrance stimulus. Participants were healthy adults and included 18 women, 6 men: age range = 18-54 years. Findings indicate significant differences such that rote tracing resulted in higher PFC activity than the creative self-expression task. Although there was no significant impact of fragrance on the overall sample, emergent differences in responsiveness to fragrance were seen by age and gender. The study suggests that repetitive tasks like rote tracing can enhance focus and the creative self-expressive tasks can reduce PFC load and induce relaxation and flow.

- Abstract
This study tests theories of social learning and strain to explain non-medical prescription drug use (NMPDU) among Latino college students at a Hispanic-Serving Institution (HSI). Logistic regression analyses indicate social learning and negative stressors help explain such usage, while refined models suggest that Latinos use of NMPD is primarily intended to improve academic performance. The study raises important questions about the unique challenges facing Latino college students and the role NMPDU may play in HSIs.

- Abstract
Objective: This study examined the prevalence and factors associated with non-medical use of prescription stimulants to promote wakefulness. Participants: We surveyed 3,160 university students aged 18-35 between June 2016 and May 2017. Method: Participants reported whether they used prescription stimulants non-medically to stay awake and completed measures of anxiety and depressive symptoms, sleep quality, insomnia, daytime sleepiness, and attitudes toward non-medical prescription drug use. Univariate and multivariate regression models were used. Results: Prevalence of non-medical prescription stimulant use to promote wakefulness was 3.1%. The following factors remained significant in the multivariate model: alcohol, tobacco, and nicotine vapor use, attitude toward non-medical use of prescription medication, poor sleep quality, and daytime sleepiness. Conclusion: Poor sleep, substance use and more liberal attitudes to non-medical prescription drug use were associated with the misuse of stimulants to promote wakefulness. Prevention/intervention programs should promote sleep hygiene and highlight the risks of using prescription drugs non-medically.

- Abstract
Substance use is a leading cause of preventable morbidity and mortality; it is in large part why, among 17 high-income nations, people in the U.S. have the highest probability of dying by age 50. Substance use is also an important contributor to many social ills including child and spouse abuse, violence more generally, theft, suicide, and more; and it typically is initiated during adolescence. It warrants sustained attention. Monitoring the Future (MTF) is designed to give sustained attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with, and is conducted by, a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been continuously funded by the National Institute on Drug Abuse--one of the National Institutes of Health--under a series of peer-reviewed, competitive research grants. The 2017 survey, reported in this report, is the 43rd consecutive survey of 12th grade students and the 27th such survey of 8th and 10th graders. This annual monograph series has been a primary vehicle for disseminating MTF's epidemiological findings. This monograph presents the results of the 43rd survey of drug use and related attitudes and beliefs among American high school seniors and 27th such survey of 8th and 10th grade students. The next monograph in this series will report the 38th such survey of American college students and same-age youth who do not attend college, as well as findings regarding substance use prevalence and trends among adults through age 60. An annual monograph on risk and protective behaviors for the spread of HIV/AIDS2 among young adults was added beginning in 2009. (In years prior to 2009, findings from the study on risk and protective behaviors related to the spread of HIV/AIDS were contained in "Volume II.")

- Abstract
The present volume presents new 2017 findings from the U.S. national Monitoring the Future (MTF) follow-up study concerning substance use among the nation's college students and adults from ages 19 through 55. The authors report 2017 prevalence estimates on numerous illicit and licit substances, examine how substance use differs across this age span, and show how substance use and related behaviors and attitudes have changed over the past four decades. MTF, now in its 44th year, is a research program conducted at the University of Michigan's Institute for Social Research under a series of investigator-initiated, competing research grants from the National Institute on Drug Abuse--one of the National Institutes of Health. The integrated MTF study comprises several ongoing series of annual surveys of nationally representative samples of 8th and 10th grade students (begun in 1991), 12th grade students (begun in 1975), and high school graduates followed into adulthood (begun in 1976). The authors report the results of the repeated cross-sectional surveys of all high school graduating classes since 1976 as they follow them into their adult years (as discussed in Chapter 3, these cross-sections come from longitudinal data). Segments of the general adult population represented in these follow-up surveys include: (1) U.S. college students; (2) their age-peers who are not attending college, sometimes called the "forgotten half,"; (3) all young adult high school graduates of modal ages 19 to 30 (or 19-28 for trend estimates), to whom we refer as the "young adult" sample; and (4) high school graduates at the specific later modal ages of 35, 40, 45, 50, and 55. This volume emphasizes historical and developmental changes in substance use and related attitudes and beliefs occurring at these age strata. The follow-up surveys have been conducted by mail on representative subsamples of the previous participants from each high school senior class. This volume presents data from the 1977 through 2017 follow-up surveys of the graduating high school classes of 1976 through 2016, as these respondents have progressed into adulthood. The oldest MTF respondents, from the classes of 1976-80, have been surveyed through age 55 in 2013-2017, 37 years after their graduation.
