RESUMO

Objective: The current study aims to compare college adjustment and the effects of the COVID-19 pandemic on first-year students with and without ADHD. Participants: Two cohorts (pre-pandemic, during the pandemic) of first-year, undergraduate college students (N = 3,006; Mage=18.32) were recruited from a multisite research consortium across several universities. Methods: First-year participants self-reported on ADHD diagnosis and symptoms, functional impairments, and experiences transitioning to college. Results: First-year college students with and without ADHD reported significantly greater academic, daily living, and overall functional impairments during the pandemic compared to pre-pandemic. Compared to college students without ADHD, college students with ADHD reported greater functional impairment, more difficulty adjusting to the academic demands of college, and were less likely to feel valued at their institution. Conclusions: First-year college students with and without ADHD experienced greater difficulties navigating the transition to college during the pandemic. Psychosocial and academic supports to help students transition to college are needed.

RESUMO

An existing theoretical framework proposes that aberrant temporal processing and a fast internal clock, denoted by overestimation and under-reproduction of time, increases the likelihood of engagement in risky behaviors (ERB). The primary aim of this project was to improve our understanding of the relationship between temporal processing and ERB in college students. The present study used the Wittmann and Paulus (2008) theoretical framework to examine the associations between temporal processing and ERB in college students. College student participants (N = 215) completed self-report measures of ERB, delay aversion, inhibitory control, ADHD symptoms and objective cognitive time estimation and time reproduction tasks. Time estimation accuracy was significantly associated with lower engagement in sexual risk behaviors (OR = .988; 95% CI: .979, .996; p = .006) and aggressive behaviors (OR = .989; 95% CI: .980, .998; p = .018). Time reproduction was not significantly associated with ERB. The present study established preliminary support for the associations between aberrant temporal processing, namely aberrant time estimation, and ERB among college students.

RESUMO

LAY ABSTRACT: Autistic individuals and those who identify with a sexual and/or gender minority are both at risk for various mental health concerns and related impairments. However, the connection between autism and sexual and/or gender minorities and mental health and functional outcomes is not clear. Here, we provide evidence of these connections by analyzing data from a large nationally representative dataset from the American College Health Association-National College Health Assessment III. We found that autistic college students who identify with both sexual and gender minorities reported the highest rates of stress, academic, and mental health concerns including suicidality when compared with autistic college students with or without a sexual and/or gender minority. In addition, college students with at least two identities, such as autism and a sexual minority identity or both a sexual and gender minority identity, reported the next highest rates of concern. These findings affirm the need for mental healthcare providers to consider the intersections of a sexual and gender minority identities in non-autistic and, especially, in autistic college students to develop and provide better support and resources.

RESUMO

Compared to the large body of maternal mental health research for other pediatric disorders, we know far less about the experience of mothers of children with 22q11DS. This study investigates the coping methods, protective factors, and mental health of this population. These findings might lead to better support for 22q11DS maternal mental health. An international sample of 71 mothers (M = 40.5 years) of children with 22q11DS (M = 9.2 years) was recruited and completed an online survey assessing maternal mental health (symptoms of depression, anxiety, traumatic stress, general stress, and alcohol consumption), coping methods, and mental health protective factors (social support, dyadic adjustment, parenting competence). Maternal ratings of child mental health symptoms were also obtained. Mothers' self-report revealed a high percentage who screened positive for elevated levels of general stress (69%), hazardous alcohol consumption (30.9%), traumatic stress (33.8%), anxiety (26.8%), and depression (26.8%). After controlling for demographic variables and child mental health symptoms, maternal self-reported maladaptive coping methods were positively associated with maternal symptoms of depression, anxiety, stress, and traumatic stress. Reducing maladaptive coping methods may be a promising intervention for improving mental health in mothers of children with 22q11DS.

RESUMO

Objective: Eight percent of college students report past year prescription stimulant misuse (nonmedical use of stimulants defined as taking stimulants in a manner other than prescribed). Despite this high prevalence rate, primary prevention efforts are lacking on college campuses. Participants and Methods: A prescription stimulant misuse primary prevention intervention targeting first-year college students was developed, refined, and pilot tested. Existing substance use treatment (motivational interviewing) and time management (cognitive behavioral therapy for adult ADHD) techniques were integrated into the novel brief prevention intervention. Focus groups provided feedback to help refine the prevention intervention. Following refinements, 484 first-year college students were randomly assigned to condition (327 treatment, 157 control) and followed for 3 months. Results: Participants rated the intervention as satisfactory. After controlling for time invariant covariates, condition significantly predicted prescription stimulant misuse. There was a lower rate of past 3-month prescription stimulant misuse reported in the intervention group (4.9%) compared to the control group (11.5%). Academic expectancies remained stable in the intervention group yet increased in the control condition over time. Time management skill ratings remained stable in both groups. Changes in academic expectancies, yet not time management skills, were a partial mediator of the prevention efficacy in prescription stimulant misuse at 3-month follow-up. Conclusions: These results provide preliminary support for the acceptability and efficacy of a brief primary prevention intervention for college student prescription stimulant misuse. Changes in positive prescription stimulant expectancies, yet not time management skills, appear to be potential targets for future preventive efforts.

RESUMO

22q11.2 deletion syndrome (22q11DS) is the most frequently occurring microdeletion in humans. It is associated with a significant impact on brain structure, including prominent reductions in gray matter volume (GMV), and neuropsychiatric manifestations, including cognitive impairment and psychosis. It is unclear whether GMV alterations in 22q11DS occur according to distinct structural patterns. Then, 783 participants (470 with 22q11DS: 51% females, mean age [SD] 18.2 [9.2]; and 313 typically developing [TD] controls: 46% females, mean age 18.0 [8.6]) from 13 datasets were included in the present study. We segmented structural T1-weighted brain MRI scans and extracted GMV images, which were then utilized in a novel source-based morphometry (SBM) pipeline (SS-Detect) to generate structural brain patterns (SBPs) that capture co-varying GMV. We investigated the impact of the 22q11.2 deletion, deletion size, intelligence quotient, and psychosis on the SBPs. Seventeen GMV-SBPs were derived, which provided spatial patterns of GMV covariance associated with a quantitative metric (i.e., loading score) for analysis. Patterns of topographically widespread differences in GMV covariance, including the cerebellum, discriminated individuals with 22q11DS from healthy controls. The spatial extents of the SBPs that revealed disparities between individuals with 22q11DS and controls were consistent with the findings of the univariate voxel-based morphometry analysis. Larger deletion size was associated with significantly lower GMV in frontal and occipital SBPs; however, history of psychosis did not show a strong relationship with these covariance patterns. 22q11DS is associated with distinct structural abnormalities captured by topographical GMV covariance patterns that include the cerebellum. Findings indicate that structural anomalies in 22q11DS manifest in a nonrandom manner and in distinct covarying anatomical patterns, rather than a diffuse global process. These SBP abnormalities converge with previously reported cortical surface area abnormalities, suggesting disturbances of early neurodevelopment as the most likely underlying mechanism.

RESUMO

OBJECTIVE: Asian American and Pacific Islander (AAPI) students with ADHD may face increased risk for college maladjustment due to cultural factors and a tendency to delay treatment. This is the first study to examine ADHD prevalence, ADHD-related impairments and comorbidities, and ADHD treatment utilization in AAPI college students. METHOD: AAPI, White, Hispanic, and Black undergraduates (n = 258,005) from the American College Health Association-National College Health Assessment II survey were included in the study. RESULTS: AAPI students had lower ADHD prevalence rates than White and Black students, and similar prevalence to Hispanic students. AAPI students with ADHD had significantly higher risk for comorbidities and social and academic impairments, compared to White students with ADHD. Approximately half of AAPI students with ADHD did not utilize treatment despite experiencing psychiatric comorbidities and functional impairments. CONCLUSION: AAPI college students with ADHD are underutilizing treatment despite elevated psychiatric comorbidities and functional impairment.

RESUMO

BACKGROUND: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and adolescents with autism aged 6-17 years. METHODS: The sample included 61 children and adolescents with autism. The Sensory Profile was used to examine Dunn's quadrant model (seeking, sensitivity, avoiding, registration), ADHD symptoms were measured using hyperactivity and attention problems BASC-2 T-scores, and autistic traits were measured using the AQ. RESULTS: After controlling for age, IQ, sex, and ADHD symptoms, Dunn's sensitivity quadrant predicted autistic traits. CONCLUSIONS: Findings provide insight into the phenotype of autism and ADHD. Sensory sensitivity may be unique to autism over and above elevated ADHD symptoms that are commonly seen in this population.

RESUMO

Understanding the mental health outcomes of sexual assault among college women is a public health priority. Although research has identified risk factors for the development of mental health problems following an assault, few studies have utilized a strengths-based approach to identify personal and social resources that may mediate the sexual assault-mental health link. Prior studies allude to the role of resilience and perceived campus belonging in explaining the relationship between sexual assault and mental health. This study represents the first application of the stress process model using a large sample of college women to examine (a) the association between sexual assault and mental health (i.e., psychological distress, suicidality, self-harm) and alcohol use problems and (b) the role of resilience and perceived campus belonging as partial mediators of these associations. Data were collected as part of the Spring 2021 American College Health Association National College Health Assessment (ACHA-NCHA; n = 31,328, Mean age = 20.26, SD = 1.64, 58.8% White), a cross-sectional, online survey that samples college students from 143 self-selected United States colleges. To test our primary hypothesis, a structural regression model was conducted, which included a latent sexual assault predictor, manifest resilience and campus belonging mediators, a latent mental health outcome, and a manifest alcohol use problems outcome. Mental health and alcohol use problems were positively associated with sexual assault and negatively associated with resilience and campus belonging. Resilience partially mediated the association between sexual assault and mental health. Campus belonging partially mediated the association between sexual assault, mental health, and alcohol use problems. This model explained 23.2% of the variance in mental health and 5.9% of the variance in alcohol use. Resilience and campus belonging may represent modifiable factors that can be targeted in trauma-focused interventions in efforts to improve victimized college women's mental health.

RESUMO

OBJECTIVE: This study aimed to assess the association between anorexia nervosa (AN), bulimia nervosa (BN), attention deficit/hyperactivity disorder (ADHD), and associated impairments (e.g., suicidality). METHODS: A secondary data analysis of the American College Health Association-National College Health Assessment IIc (Fall 2015-Spring 2019) was conducted to assess the prevalence of comorbid anorexia or bulimia + ADHD, symptoms, and impairments among college student (N = 342,432; Mage  = 20.39, SD = 1.88). Logistic regressions were used to compare eating disorder symptomology, treatment utilisation, and suicidality among college students. RESULTS: Compared to college students without ADHD, college students with ADHD were 18.30× more likely to be diagnosed with anorexia or bulimia and reported greater use of weight loss techniques (p's < 0.001). College students with comorbid anorexia or bulimia + ADHD reported higher rates of dieting to lose weight (aOR = 1.27, 95% CI: 1.12, 1.43, p < 0.001) and treatment utilisation (aOR = 1.30, 95% CI: 1.06, 1.50, p < 0.001) compared to college students with AN or BN only. The highest level of suicidality was reported in college students with the comorbid AN or BN + ADHD. CONCLUSION: Elevated eating disorder symptoms and comorbidity is found among college students with ADHD. Increased screening and prevention for anorexia and bulimia is needed among young adults with ADHD to enhance care for those with these eating disorders.

RESUMO

Children with autism spectrum disorder (ASD) often exhibit challenging behaviors. Existing behavioral parent trainings (BPT) address ASD symptomology, but are lengthy and associated with significant attrition. In the current pilot study, a longitudinal randomized controlled trial was used to evaluate a novel brief BPT targeting caregivers of children with ASD ages 5-9. The 6-session BPT, delivered in a group format, focused on high-frequency challenging behaviors (e.g., problem behaviors, feeding and sleep issues). Caregivers who received BPT (n = 29), relative to an active control (psychoeducation/supportive therapy; n = 9), reported higher treatment satisfaction and acceptability. Challenging behaviors were reduced in the BPT and active control groups. The novel BPT was a feasible and acceptable intervention to target challenging behaviors in youth with ASD.

RESUMO

Objective: Poor sexual health is a public health concern for college students and individuals with attention-deficit/hyperactivity disorder (ADHD), yet limited information is available on the sexual health of college students with ADHD. Here, the sexual health of college students with and without ADHD was described and moderators of risk to sexual health were identified.Methods: A secondary data analysis of the National College Health Assessment III (Fall 2019, Spring 2020, and Fall 2020 administrations) was conducted using a sample of sexually active undergraduate students (N = 36,236). Logistic regressions were used to compare sexual behaviors and health outcomes of college students with and without self-reported ADHD and test for interactions between ADHD and substance use-related moderators of risk to sexual health (ie, alcohol use, binge drinking, and cannabis use).Results: Compared to non-ADHD peers, college students with ADHD reported more past-year sexual partners (adjusted odds ratio [aOR] = 1.27; P < .01), lower rates of condom use (aOR = 0.77; P < .001), and higher rates of condomless sex while drinking (aOR = 1.52; P < .001). College students with ADHD reported more sexually transmitted infection diagnoses (aOR = 1.29; P < .01), a greater number of unplanned pregnancies (aOR = 1.72; P < .001), and more emergency contraception use (aOR = 1.19; P < .001). Alcohol use, binge drinking, and cannabis use moderated the relationship between ADHD and sexual health.Conclusions: College students with ADHD represent a vulnerable population for poor sexual health and are differentially impacted by substance use. Indicated sexual health prevention strategies and treatment for college students with ADHD are warranted.

RESUMO

Attention deficit/hyperactivity disorder (ADHD) is characterized as a neurodevelopmental disorder. However, data from several recent studies suggest that there may be adults who meet current criteria for ADHD, yet did not experience symptoms until adulthood (i.e., "adult-onset ADHD"). This systematic review evaluated and synthesized the empirical evidence on adult-onset ADHD to answer the question: Is the extant literature strong enough to evaluate adult-onset ADHD? Nine studies met strict inclusion/exclusion criteria. Results suggest that the methodologies of the extant studies were not strong enough to evaluate adult-onset ADHD. Insufficient methodologies provide presently unclear information about the nature of late-onset symptoms. These symptoms seem to exist but their source could be (1) adult-emergent symptoms that were previously surpassed due to lower environmental demands/supportive facilitators, (2) mimics that were not properly assessed, or (3) childhood-onset symptoms that were not detected earlier due to failure to come to clinical attention. Future directions, clinical recommendations, and limitations of the literature and the current review are discussed.

RESUMO

OBJECTIVE: Increased prescription stimulant nonmedical use (NMU) is part of a growing polysubstance use landscape. The purpose of the present study was to characterize prescription stimulant NMU among adults reporting past 5-year non-oral prescription stimulant NMU. METHODS: Adults who reported non-oral prescription stimulant NMU within the last 5 years were recruited by banner ads placed on the Reddit website between February and September 2019. Types of prescription stimulants used, routes of administration, preferred routes of administration, motivations for prescription stimulant NMU, concurrent substances used simultaneously during prescription stimulant NMU, illicit substances used and factors impacting prescription stimulant NMU were queried. RESULTS: Respondents (n = 225) were male (86.2%), non-Hispanic (92.4%), white (78.2%), between 18 and 24 (48.0%) or 25-34 (43.1%) years with some amount of college education (81.3%). Most reported lifetime intranasal (93.8%) or oral use (85.2%). Prescription stimulants were diverted: 64.5% reported the prescription stimulants were given to them by a family or a friend and 10.5% reported that they had stolen these medications from a family or friend. Preferred route of administration was oral use (70.2%). Motivations to use were stratified by route of administration: intranasal (55.6%) or oral (63.0%) use was primarily endorsed as an attempt to enhance performance at work or at school; use by injection (57.1%) or smoking (62.5%) was primarily endorsed to get high. Most of the sample reported concurrent drug use (79.1%) including tobacco (57.3%), marijuana (52.0%), caffeine (47.6%) or alcohol (41.8%), among others. When excluding licit substances, 30.7% reported using 1 illicit substance concurrently with prescription stimulants and 25.3% reported using 2 or more illicit substances concurrently with prescription stimulants. Whether participants would undertake prescription stimulant NMU was determined by their work/school schedules or the location of the NMU (48.9%) whereas the route of administration employed was primarily influenced by the desired feeling or effect (56.9%). CONCLUSIONS: Adults reporting lifetime non-oral prescription stimulant NMU engage in substantial risky behaviors that in addition to alternate routes of administration include polysubstance use, diversion and concurrent substance use.

RESUMO

Introduction: Non-medical use (NMU) of prescription stimulant medications is a continuing public health concern. Stimulant medications prescribed for attention-deficit/hyperactivity disorder (ADHD) are widely available on college campuses, and, as a consequence, college students may have multiple opportunities to engage in prescription stimulant NMU. This online self-report survey examined prescription stimulant NMU among college students, including: (1) patterns of non-oral route of administration (ROA); (2) motivations for non-oral ROAs; and (3) retrospectively recalled pathways of initiation. Method: The survey sample was created from a pool of 3,379 respondents, who were matched to a sampling frame constructed from the 18-26-year-old, college student sample of the 2016 American Community Survey (ACS). About 14% (n = 486) from the overall pool were identified as college students with self-reported prescription stimulant NMU, all of whom completed the survey. The survey covered user characteristics, prescription and illicit substance use, age of first NMU, motivations for NMU, sources of procurement, and ROAs used. Results: Among 486 students reporting prescription stimulant NMU, 43% had a lifetime diagnosis of ADHD. More than 90% reported polysubstance use, with 55% using illicit substances other than marijuana. Slightly more than 2 in 5 (43.3%) reported using illicit substances prior to prescription stimulant NMU, 24.6% used both at the same age, and 32.0% engaged in NMU of prescription stimulants prior to using illicit substances. Prescription stimulant NMU preceded prescription opioid NMU 45% of the time. More than a quarter of those engaged in prescription stimulant NMU (27.9%) initiated prescription stimulants alone or at the same age as other drugs. Most prescription stimulant NMU was oral, however 23.0% reported any non-oral use: snorting (20.4%), smoking (6.0%)and/or injection (3.5%). Non-oral use was associated with being male, obtaining medication from a dealer, use to get high, and/or a substance use disorder diagnosis. Conclusions: Prescription stimulant NMU often occurs in the larger context of other substance use among college students. Injection, an under-researched route for prescription stimulants, was associated with male gender, history of substance use and higher likelihood of illicit substance use. Nearly a quarter of college student survey respondents reported use with non-oral routes, which is associated with other high-risk behaviors. Efforts to reduce non-oral prescription stimulant NMU in college students are warranted.

RESUMO

OBJECTIVE: 22q11.2 deletion syndrome (22q11DS) is a common genetic deletion syndrome associated with psychiatric disorders and developmental delays. A significant amount of 22q11DS research literature is published annually; here, we focus exclusively on longitudinal data that have been published in the past 5 years regarding psychiatric disorders and/or cognitive and social development. After a review, areas for future research consideration and clinical recommendations are presented. METHODS: Articles were reviewed and organized in adherence with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for conducting systematic reviews. The literature search identified 852 studies, and 22 studies met inclusion criteria. RESULTS: Longitudinal study findings indicate that developmental considerations for youth with 22q11DS should focus on the primacy and enduring nature of social and executive functioning deficits, attention-deficit/hyperactivity disorder, anxiety, and negative symptoms of psychosis. CONCLUSION: From the diathesis of physiological conditions and genetic variance, 22q11DS and its associated phenotype of persistent cognitive deficits, comorbid psychiatric disorders, and social impairments likely conspire to increase the risk for stress in adolescence. The diathesis-stress framework, along with chronic stress, increases psychosis risk in individuals with 22q11DS. The existing literature has a heavy focus on the impact of the deletion on individual skills and attributes, such as cognition, but lacks information on the impact of the environment. Future 22q11DS research should consider specific aspects of social functioning, including interactions with parenting styles and family communication, as well as high demands in educational settings, as possible risk factors for psychosis.

RESUMO

The 22q11.2 deletion syndrome (22q11DS) is a developmental genetic syndrome associated with a 30% risk for developing schizophrenia. Lateral ventricles and subcortical structures are abnormal in this syndrome as well as in schizophrenia. Here, we investigated whether these structures are related in young adults with 22q11DS with and without prodromal symptoms (PS) for schizophrenia and whether abnormalities in volumes are associated with global functioning. MR images were acquired on a 3T scanner from 51 individuals with 22q11DS and 30 healthy controls (mean age: 21±2 years). Correlations were performed to evaluate the relationship between ventricular and subcortical volumes, with Global Assessment of Functioning (GAF) and Premorbid Adjustment Scale (PAS) in each group. Lateral ventricular volumes correlated negatively with subcortical volumes in individuals with 22q11DS. In individuals with 22q11DS with PS only, GAF correlated positively with volumes of the lateral ventricles and negatively with subcortical volumes. PAS correlated negatively with lateral ventricle volumes, and positively with volumes of subcortical structures. The results suggest a common neurodevelopmental mechanism related to the growth of these brain structures. Further, the ratio between the volumes and clinical measures could potentially be used to characterize individuals with 22q11DS and those from the general population for the risk of the development of schizophrenia.

RESUMO

OBJECTIVE: Certain copy number variants (CNVs) greatly increase the risk of autism. The authors conducted a genetics-first study to investigate whether heterogeneity in the clinical presentation of autism is underpinned by specific genotype-phenotype relationships. METHODS: This international study included 547 individuals (mean age, 12.3 years [SD=4.2], 54% male) who were ascertained on the basis of having a genetic diagnosis of a rare CNV associated with high risk of autism (82 16p11.2 deletion carriers, 50 16p11.2 duplication carriers, 370 22q11.2 deletion carriers, and 45 22q11.2 duplication carriers), as well as 2,027 individuals (mean age, 9.1 years [SD=4.9], 86% male) with autism of heterogeneous etiology. Assessments included the Autism Diagnostic Interview-Revised and IQ testing. RESULTS: The four genetic variant groups differed in autism symptom severity, autism subdomain profile, and IQ profile. However, substantial variability was observed in phenotypic outcome in individual genetic variant groups (74%-97% of the variance, depending on the trait), whereas variability between groups was low (1%-21%, depending on the trait). CNV carriers who met autism criteria were compared with individuals with heterogeneous autism, and a range of profile differences were identified. When clinical cutoff scores were applied, 54% of individuals with one of the four CNVs who did not meet full autism diagnostic criteria had elevated levels of autistic traits. CONCLUSIONS: Many CNV carriers do not meet full diagnostic criteria for autism but nevertheless meet clinical cutoffs for autistic traits. Although profile differences between variants were observed, there is considerable variability in clinical symptoms in the same variant.

RESUMO

Objective: The prevalence of stimulant medication misuse is rising in college students. Motivations to use stimulant medications differ from motivation to use other substances such as alcohol or cannabis. However, no previous research has examined the impact of achievement goal orientation on stimulant misuse in college students. Participants: 309 college students (mean age = 18.9; 117 males) without an ADHD diagnosis were invited to participate. Methods: Participants completed an online research questionnaire that assessed factors associated with stimulant medication misuse as well as achievement goal orientations (Learning and Performance Orientations). Results: Approximately 12% endorsed a history of stimulant misuse within the past year. More males (17.1%) than females (9.4%) reported stimulant misuse. Those with and without a history of stimulant misuse differed on Performance Orientation (misuse > no misuse) yet were comparable on Learning Orientation. Conclusions: Having a higher Performance Orientation independently predicted stimulant misuse.
