Adherence to Attention-Deficit/Hyperactivity Disorder Medication During the Transition to College

ADHD Assessment and Treatment Services in a Sample of U.S. Colleges and Universities

OBJECTIVE

Up to 2 million college students in the United States have been diagnosed as having attention-deficit hyperactivity disorder (ADHD), a condition associated with negative academic, social, and psychiatric outcomes. The authors investigated the online availability and content of policies governing ADHD services at college clinics.

METHODS

Using a stratified sample of 200 colleges and universities, the authors reviewed clinic websites and invited clinical staff to participate in a survey. They weighted percentages to account for oversampling and used regression modeling to examine associations with policy availability.

RESULTS

Only 70 institutions (32%, weighted percentage) provided information about ADHD services online. Institutions with <1,000 students had significantly lower odds of providing information online (adjusted odds ratio [AOR]=0.04, 95% CI=0.01-0.26), as did institutions that accepted >67% of applicants (AOR=0.18, 95% CI=0.07-0.48). After merging data from the Web review and survey, the authors noted that 14% (N=11 of 75 institutions with data available for this variable) facilitated neuropsychological assessments on campus, 49% (N=33 of 72) did not allow stimulant medications to be prescribed, 73% (N=43 of 61) did not offer clinical evaluations for ADHD, and 89% (N=32 of 35) required a neuropsychological assessment to receive prescription stimulants.

CONCLUSIONS

Information about the assessment and management of ADHD is rarely available online, and ADHD services on U.S. college campuses appear to be limited.

Short- and Long-Term Outcomes of Suboptimal Medication Adherence in Adolescents with Attention-Deficit/Hyperactivity Disorder: A Systematic Literature Review

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition with severe and life-long consequences. Adolescents and young adults represent a particularly vulnerable subgroup because of the unique demands of their developmental stage. Despite the well-known efficacy of medication treatment for ADHD, there remains a notable concern regarding poor medication adherence in this population. Objectives: This systematic literature review aimed to synthesize the existing empirical evidence on the outcomes and consequences of medication nonadherence among adolescents and young adults with ADHD. Methods: An extensive database search was conducted on September 26, 2022, with no time limits applied. The databases included Scopus, PubMed, CINAHL, Cochrane, and PsycINFO. Results: Six studies met the inclusion criteria. Each study revealed that medication nonadherence was associated with a range of adverse outcomes, including decreased academic performance, heightened familial, and psychological stress, and an increased likelihood of substance use, pregnancy, obesity, and injury. Conversely, adherence led to improvements in at least one ADHD-related outcome. Conclusions: Research exploring the consequences of suboptimal medication adherence in adolescents and young adults with ADHD is currently limited, and effective strategies to address this issue remain scarce. A thorough understanding of such consequences is critical for developing interventions aimed at improving medication adherence and mitigating the risk of adverse outcomes, especially considering the susceptibility of this population.

College student behaviors and preferences in community pharmacies

Objective: The primary goal of conducting this research was to gain insight into what characteristics of a community pharmacy college students may find appealing and how community pharmacies can tailor their services toward college students. Participants: The survey was distributed to 3,000 college students at The University of Mississippi from various schools and majors across campus. A total of 188 students participated by completing questions from the survey. Methods: The research was performed by using a cross-sectional online survey, and basic descriptive statistics, including frequency counts were used to characterize the findings. Statistical analyses, including crosstabs and chi-square analyses, were used to determine if there were any significant (p < 0.05) associations between characteristics such as pharmacy preferences and other variables. Results: Results of this survey indicated that the majority of respondents have used a community pharmacy in the past six months, and a small number of participants are interested in using a pharmacy for more than the sole reason of filling a prescription. Results also showed that insurance and convenience were the two most influential factors in choosing a community pharmacy. Conclusion: The findings presented in this study show a number of opportunities for community pharmacies to improve the health of college students and their communities.

Transition care for adolescents and young adults with attention-deficit hyperactivity disorder (ADHD): A descriptive summary of qualitative evidence

The review presents a summary of available evidence about transition care of ADHD patients from all service users' perspectives. Common barriers, and suggestions for improvement ADHD of transition care, were extrapolated from qualitative research, including case notes studies, and were exposed. A comprehensive search of the PubMed, Embase, PsychInfo and Web of Science databases for articles published up to October 2021 was conducted to summarize recent evidence on the experiences of all stakeholders involved in the transition process. Reviews, other chronic conditions and different meaning of transition were excluded. Authors extracted data and assessed study quality independently. Findings were discussed taking into consideration barriers and suggestions from all service users' perspectives. Findings from 23 studies with different context and methods were collected and summarized. Most of the studies were conducted in UK, using interviews and questionnaires, and addressed to the physicians. The lack of information about ADHD as a condition and about transition process were the barriers most reported, while joint working and sharing transition protocols were the suggestions pointed out by all stakeholders. Despite different perspectives, all stakeholders exposed similar needs. The review reveals an evident need for defining and evaluating the effectiveness of transition programmes from child to adult ADHD services.

Why young people stop taking their attention deficit hyperactivity disorder medication: A thematic analysis of interviews with young people

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that can persist into adulthood. Young people often stop taking ADHD medication during adolescence despite evidence that continuation would be beneficial. Increasingly, young people are restarting medication in early adulthood suggesting that cessation was premature. In this paper we explore the reasons given by young people for discontinuing ADHD medication.

METHODS

Qualitative data from the Children and Adolescents with ADHD in Transition between Children's and Adult Services (CATCh-uS) project was analysed to look for reasons for stopping medication. Semi-structured interviews with three groups of young people were analysed using thematic and framework analysis; this included young people prior to transition (n = 21); young people that had successfully transitioned to adult services (n = 22); and young people who left children's services prior to transition but re-entered adult services later (n = 21).

RESULTS

Reasons given by young people for stopping ADHD medication included the following: the perceived balance between benefits and adverse effects of medication; perceptions of ADHD as a childhood or educational disorder; life circumstance of the young person and challenges young people faced in accessing services.

CONCLUSIONS

A multidimensional approach is needed to address discontinuation of ADHD medication in order to improve the long-term prospects and quality of life for these young people. Possible approaches include access to non-pharmacological treatments and improved psychoeducation. As many reasons given by young people are not unique to ADHD, these findings are also of relevance to medication adherence in other chronic childhood conditions.

New Drugs to Treat ADHD: Opportunities and Challenges in Research and Development

Since the landmark MTA (Multimodal Treatment of ADHD) trial unequivocally demonstrated the efficacy of methylphenidate, catecholaminergic drugs, especially stimulants, have been the therapeutic mainstay in treatment of Attention-Deficit Hyperactivity Disorder (ADHD). We review the new drugs which have entered the ADHD formulary. The lessons learned from drug-candidates that have succeeded in clinical trials together with those that have not have also been considered. What emerges confirms and consolidates the hypothesis that clinically effective ADHD drugs indirectly or directly increase catecholaminergic neurotransmission in the prefrontal cortex (PFC). Attempts to enhance catecholaminergic signalling through modulatory neurotransmitter systems or cognitive-enhancing drugs have all failed. New drugs approved for ADHD are catecholaminergic reuptake inhibitors and releasing agents, or selective noradrenaline reuptake inhibitors. Triple reuptake inhibitors with preferential effects on dopamine have not been successful. The substantial number of failures probably accounts for a continued focus on developing novel catecholaminergic and noradrenergic drugs, and a dearth of drug-candidates with novel mechanisms entering clinical development. However, substantial improvements in ADHD pharmacotherapy have been achieved by the almost exclusive use of once-daily medications and prodrugs, e.g. lisdexamfetamine and Azstarys^®, which improve compliance, deliver greater efficacy and reduce risks for diversion and abuse.

Disruption of Pharmacotherapy During the Transition from Adolescence to Early Adulthood in Patients with Attention-Deficit/Hyperactivity Disorder: A Claims Database Analysis Across the USA

BACKGROUND AND OBJECTIVE

Attention-deficit/hyperactivity disorder (ADHD) treatment rates in adults are low, possibly owing to discontinuation of pediatric care due to various circumstances (including inadequate health insurance coverage, poor disease insight, and patient/family resistance, as well as those who manage their ADHD independent of pharmacologic intervention) during the transition from adolescence to adulthood. To improve the understanding of treatment patterns during this transition, this study characterized pharmacotherapy use in patients with ADHD aged 16-21 years.

METHODS

A retrospective claims analysis of the IBM^® MarketScan^® Commercial Databases, which represent all census regions of the USA, included patients aged 16-21 years with two or more ADHD diagnoses between 1/1/2008 and 12/31/2017 (one or more diagnoses during the year of age 17) who were continuously enrolled from ages 16-21 years and prescribed ADHD medication for ≥ 6 months at age 17 years. Pharmacotherapy use was assessed longitudinally. Comparisons between ages were conducted using Wilcoxon signed-rank tests and McNemar tests. Treatment discontinuation was estimated using Kaplan-Meier analyses.

RESULTS

The analysis included 10,292 patients. The overall percentage of patients receiving pharmacotherapy significantly decreased (p < 0.001, regardless of treatment type and presence of co-occurring psychiatric disorders) as patients aged, with a median time to treatment discontinuation of 2.94 years. Among patients using pharmacotherapy at the age of 17 years, more than 30% were no longer using pharmacotherapy at age 21 years. As patients aged, the percentage using long-acting amphetamines or methylphenidates decreased, and the percentage receiving no treatment increased. The percentage of patients with disrupted treatment from age 18 to 21 years ranged from 17.9 to 24.1%. After transitioning to disrupted treatment or no treatment, low percentages of patients returned to pharmacotherapy use (disrupted treatment: 15.7-21.5% per year; no treatment, 2.7-3.8% per year). Across all age groups, statistically significantly greater (p < 0.05) percentages of patients with co-occurring psychiatric disorders used lisdexamfetamine, dextroamphetamine-amphetamine mix short acting, and non-stimulants compared with patients without co-occurring psychiatric disorders. Patients with co-occurring psychiatric disorders remained on ADHD pharmacotherapy longer and switched or augmented their pharmacotherapy more frequently than patients without co-occurring psychiatric comorbidities.

CONCLUSIONS

Patients rarely reinitiated treatment after pharmacotherapy was disrupted or discontinued, emphasizing the need for increased focus on the management of ADHD as patients transition from adolescence to adulthood.

How to say "no" most effectively: Evaluating resistance strategies for prescription stimulant diversion to inform preventive interventions

We evaluated the perceived effectiveness of resistance strategies students could employ if approached to give away, trade, or sell their prescription stimulant medication, a growing concern on college campuses. Participants: We sampled undergraduates (N = 1,521) at three demographically dissimilar institutions between Fall 2017 and Spring 2018. Methods: We administered an anonymous, online survey and used linear mixed models to examine the effects of strategy type, face support (ie, adding politeness), and substance use history on perceived strategy effectiveness. Results: Internal (eg, "I am not comfortable sharing my medication") and external (eg, "My doctor won't prescribe me if I share") explanations were perceived to be most effective. Excuses, direct refusals, and suggesting an alternative (eg, energy drink) were less preferred. Adding face support improved perceived effectiveness for direct refusals and internal explanations. Conclusion: Preventive interventions for stimulant diversion could encourage the use of internal or external explanations or direct refusals with face support.

Unmet care needs of children with ADHD

Background

Non-compliance to, or drop-out from treatment for childhood ADHD, result in suboptimal outcome. Non-compliance and drop-out may be due to mismatches between patients' care needs and treatments provided. This study investigated unmet care needs in ADHD patients. Unmet needs were assessed in two different treatment settings (general outpatient setting versus youth-ACT). Youth-ACT treatment is an intensive outreach-oriented treatment for patients with severe psychiatric and psychosocial problems. Comparison of a general outpatient sample with a youth-ACT sample enabled us to assess the influence of severity of psychiatric and psychosocial problems on perceived care needs.

Methods

Self-reported unmet care needs were assessed among 105 ADHD patients between 6 and 17 years of age in a general outpatient (n = 52) and a youth-ACT setting (n = 53).

Results

ADHD patients most frequently reported unmet needs regarding mental health problems, information on diagnosis/treatment, and future prospects. Outpatients differed from youth-ACT patients with respect to 30% of the unmet care needs that were investigated. Outpatients perceived more unmet needs regarding information on diagnosis/treatment (p = 0.014). Youth-ACT patients perceived more unmet needs concerning medication side effects (p = 0.038), quality and/or quantity of food (p = 0.016), self-care abilities (p = 0.016), regular/suitable school or other daytime activities (p = 0.013), making and/or keeping friends (p = 0.049), and future prospects (p = 0.045).

Conclusions

Focusing treatment of ADHD patients on unmet needs may reduce non-compliance and drop-out. In clinical practice, systematic assessment of unmet care needs in all ADHD patients may be warranted, e.g. using the CANSAS questionnaire during the screening/intake phase.

Barriers to Treatment Adherence Among College Students with Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

The current study sought to obtain a longitudinal perspective of and quantitatively assess barriers to medication adherence experienced by college students with attention-deficit/hyperactivity disorder (ADHD). Thus, we examined semester-long trends in barriers to adherence in addition to the relationships between barriers and medication adherence and barriers and quality of life.

METHODS

Participants were college students diagnosed with ADHD. Throughout a Fall semester, participants completed 4 sets of online questionnaires and attended 4 in-person visits, which included pill counts and written questionnaires. Participants completed measures assessing barriers to adherence and health-related quality of life, and adherence was measured via pill counts. Mean values of barriers, adherence rate, and quality of life were used for all analyses.

RESULTS

Of the 45 students surveyed, mean adherence rate was 56.70%, and 84.45% of participants reported at least 1 barrier. Across the semester, participants reported experiencing an average of 3.07 barriers, and a consistent barrier reported was not realizing when pills run out. Although reported barriers were unrelated to adherence, the results showed that barriers were associated with lowered quality of life, specifically lower overall quality of life in addition to lower emotional functioning, psychosocial health, school functioning, and physical functioning.

CONCLUSION

Barriers to adherence appear to be common in college students with ADHD, and certain barriers are consistent with the planning difficulties observed in individuals with ADHD. Because students experiencing more barriers had lower quality of life, interventions are needed to improve students' overall illness management experience.

Predictors of Prescription Stimulant Misuse in U.S. College Graduates

Background: Research has shown that prescription stimulant misuse (PSM) is prevalent among college students and that full-time college attendance is associated with PSM following graduation. Few studies, however, have examined predictors of PSM in college graduates. Objectives: We examined constructs from the Theory of Triadic Influence (TTI) to determine predictors of PSM in this population. Methods: We utilized Amazon's Mechanical Turk and snowball sampling in 2018-2019 to anonymously survey 219 adults in the United States (56% male, M_age = 32.5) with a college degree and history of college PSM. We assessed sensation seeking, ADHD symptoms, negative affect, social norms, workload, positive beliefs and perceived safety, other substance use, PSM motivations, and source(s) of prescription stimulants. Measures were administered online. Results: Over half (55%) of participants reported PSM after college; 36% used in the previous year. Ordinal logistic regressions for each domain of the TTI (i.e. intrapersonal, social/normative, cultural/attitudinal) showed that college graduates engaging in PSM in the previous year were younger and reported higher sensation seeking, more friends/coworkers who engaged in PSM, a heavier workload, and more positive beliefs about PSM. Chi-square analyses showed that college graduates engaging in PSM in the previous year also were more likely to use other substances (e.g. prescription opioids, tobacco/nicotine, cocaine) and to have misused stimulants in college to socialize or to get high. Conclusions: Preventive interventions could target college students and recent graduates who engage in PSM and who demonstrate the aforementioned risk factors, with the goal of curbing PSM and possibly other substance use.

In transition with ADHD: the role of information, in facilitating or impeding young people's transition into adult services

BACKGROUND

Many national and regional clinical guidelines emphasise the need for good communication of information to young people and their parent/carers about what to expect during transition into adult services. Recent research indicates only a minority of young people in need of transition for Attention Deficit Hyperactivity Disorder (ADHD) experience continuity of care into adulthood, with additional concerns about quality of transition. This qualitative study explored the role that information plays in experiences of transition from the perspectives of parent/carers and young people.

METHODS

Participants were recruited from 10 National Health Service Trusts, located across England, with varying service configurations. Ninety two qualitative interviews were conducted: 64 with young people with ADHD at different stages relative to transition, and 28 with parent/carers. Thematic analysis of data was completed using the Framework Method.

RESULTS

Interviewees reported a range of experiences; however reliance on parent/carers to gather and translate key information, and negative experiences associated with poor communication of information, were universal. Three themes emerged: Navigating information with help from parents; Information on ADHD into adulthood; Information about the transition process. The first revealed the essential role of parent in the translation and application of information, the other two explored distinct types of information necessary for a smooth transition. Interviewees made recommendations for clinical practice similar to UK (United Kingdom) National Institute for Health and Care Excellence (NICE) guidelines, with an additional emphasis on providing nuanced information on ADHD as a potentially long term condition. It was important to interviewees that General Practitioners had a basic understanding of adult ADHD and also had access to information about service provision.

CONCLUSIONS

Our findings illustrate that the availability and communication of information to young people and their parent/carers is an essential component of the transition process between child and adult ADHD services. How and when it is provided may support or impede transition. This study constitutes a substantial contribution to the evidence base, drawing on interviews from a range of participants across England and from Trusts offering different types of services.

Responsibility for Asthma Management Among Adolescents With and Without Attention-Deficit/Hyperactivity Disorder

PURPOSE

Among diverse, low-income urban adolescents with persistent asthma, we examined whether attention-deficit/hyperactivity disorder (ADHD) comorbidity, compared with asthma alone, was associated with clinical outcomes, healthcare utilization, and responsibility for self-management.

METHODS

We conducted a secondary analysis of data from a large school-based study of adolescents with asthma in Rochester, NY. Adolescents reported asthma symptoms over 2 weeks and primary care and hospital admissions over 1 year. We assessed shared responsibility for asthma management between caregivers and adolescents.

RESULTS

ADHD comorbidity was common (28%) in this sample of 370 adolescents. Adolescents with ADHD had more primary care utilization and hospitalizations than those without, despite having similar asthma symptoms. Caregivers and adolescents with ADHD reported that adolescents had less shared responsibility for nine asthma management tasks.

CONCLUSIONS

Adolescents with ADHD share less responsibility for asthma self-management. These teens' increased healthcare use might provide opportunities for clinicians to provide extra self-management support.

A Review of Factors Influencing the Three Phases of Medication Adherence in People with Attention-Deficit/Hyperactivity Disorder

Objectives: Factors affecting adherence to medications in people with attention-deficit/hyperactivity disorder (ADHD) are not well understood in the context of their influence on the different phases of adherence, that is, initiation, implementation, and discontinuation. This review aimed to identify the factors affecting the three phases of medication adherence in people with ADHD. Methods: Six electronic databases, including Medline, PubMed, IPA, CINAHL, Embase, and PsycINFO, were systematically searched from inception through October 2018 with the limitations of English language and human studies. The search strategy was based on three concepts (adherence, ADHD, and factors) and their relevant terminologies. Results: Considerable variability was observed with regards to the criteria used to define adherence in identified studies (n = 48). Most studies focused on the implementation phase of adherence (n = 27), while only a handful focused on the initiation (n = 6) and discontinuation (n = 5) phase of adherence. The remaining studies (n = 10) examined multiple phases of adherence. Conflicting information received about medication, medication frequency, and fears of medication's effect on growth were the unique factors impacting initiation, implementation, and discontinuation, respectively. Moreover, factors within each phase of adherence also differed with different populations such as parents, children, adolescents, and adults. Fear of addiction, medication effectiveness, psychiatric comorbidity, and medication side effects were the most common factors identified in all three phases of adherence. Conclusions: This review found some unique factors in each phase of adherence while some overlap was also noted. Future interventions to improve adherence should be phase- and group specific rather than consider adherence as a single variable.

Subjective Versus Objective Measures of Medication Adherence in Adolescents/Young Adults with Attention-Deficit Hyperactivity Disorder

OBJECTIVE

To examine the frequency of medication nonadherence using both objective and subjective data and to compare the differences between these measures in adolescents and young adults (AYAs) with attention-deficit hyperactivity disorder (ADHD).

METHOD

Fifty-four participants enrolled. Frequency (mean percent of prescribed doses not taken) of nonadherence was measured using subjective (visual analog scale) and objective (pill count and electronic monitoring) methods. Differences between measures were compared using t tests and analysis of variances.

RESULTS

Objective measures showed that participants missed 40% to 43% of their prescribed doses. Contrastingly, subjective measures indicated that participants missed 25% of their prescribed doses. Frequency of nonadherence was significantly higher when relying on objective measures rather than on subjective measures (t[46] = -4.51, p < 0.01 for pill counts, and t[47] = -4.81, p < 0.01 for electronic monitoring).

CONCLUSION

Nonadherence is high in AYAs with ADHD. These individuals tend to overestimate their adherence when self-reporting. Physicians should exercise caution when prescribing based on patient report of adherence and use objective measures when possible.

Parent Perceptions of Their College Students' Self-Management of Attention-Deficit/Hyperactivity Disorder

PURPOSE

The present study examines parents' perspectives of the experiences and challenges surrounding self-management of Attention-Deficit/Hyperactivity Disorder (ADHD) in their college students.

METHODS

Participants were parents of emerging young adults with ADHD prescribed daily medication for their condition. Thirteen individual interviews were conducted using a semistructured interview script guided by the Health Belief Model. The qualitative data were analyzed via directed content analysis.

RESULTS

Five themes emerged from the interviews: (1) parents are heavily involved in their child's self-management prior to college, and the abrupt transition of responsibilities is difficult for parents; (2) parents' worries about their child's self-management and functioning are exacerbated by privacy laws and poor communication from child and university; (3) volitional nonadherence is high; (4) obtaining academic accommodations is difficult; and (5) parents recommend a gradual transition, desire enhanced communication from the college, and wish for social support resources in the college setting for their children.

CONCLUSIONS

Parents of college students with ADHD are distressed and frustrated by the transition to college. They express the desire to remain continually involved in their child's self-management of ADHD, but several barriers hinder their ability to do so, resulting in fear of the potential consequences on their child's functioning. This collateral information from parents regarding the challenges associated with ADHD self-management experiences in college should result in the development of comprehensive interventions to improve the quality of life in college students with ADHD.

Transition to College and Adherence to Prescribed Attention Deficit Hyperactivity Disorder Medication

OBJECTIVE

As youth with attention deficit hyperactivity disorder (ADHD) transition to adulthood, they must learn how to manage their ADHD treatment independently. This may be challenging because many of the skills necessary to adhere to treatment (e.g., organization, planning) are impaired in those with ADHD. Using electronic monitoring, we examine trajectories of adherence to medication in a cohort of college students with ADHD. Further, we examine the effect of transitioning to college and executive functioning on adherence.

METHODS

Electronic monitors tracked adherence for 51 undergraduate students with ADHD across an academic semester. Multilevel modeling examined individual trajectories in monthly adherence and the role of transition status and self-reported executive functioning on these trajectories.

RESULTS

Overall, participants adhered to 53.53% of prescribed doses. Transition status predicted the linear slope in adherence (β = -8.95, standard error [SE] = 3.61, p < .05), with lower initial adherence among undergraduates transitioning to independence (34.17%) compared with post-transition undergraduates (67.63%; β = 33.46, SE = 8.00, p < .001). Adherence demonstrated a curvilinear change (β = -7.23, SE = 1.25, p < .001). It increased from the beginning of the semester to midterms before subsequently declining through the rest of the semester, including during final exams. Executive functioning did not predict adherence (β = -.10, SE = .02, p = .54).

CONCLUSION

Only half of all doses were taken as prescribed. Adolescents transitioning to independence demonstrated the lowest levels of adherence, suggesting that the transition to independence is a high-risk period for poor self-management of ADHD.
