TRANSTORNO DE DÉFICIT DE ATENÇÃO E HIPERATIVIDADE EM ADULTOS: PREJUÍZOS ADVINDOS DO DIAGNÓSTICO TARDIO

Attention deficit hyperactivity disorder is a neurodevelopmental disorder characterized by frequent changes in attention and motor activity. An individual affected by the disorder usually presents a persistent pattern of inattention and/or hyperactivity that impairs the functioning of their executive functions. When present in adults, it brings numerous significant impacts such as: affective-emotional, academic and professional performance, financial management, interpersonal relationships, marital relationships and parenting. Therefore, the general objective of this study is to evaluate the losses resulting from the late diagnosis of ADHD in adults. The methodology used was documentary and descriptive for literature, which included the analysis of existing material, especially books and scientific articles. It is clear that adolescents and adults have less hyperactivity than children, but there is a significant deficit in executive functions, which can compromise their intellectual development. The symptoms that an individual with this disorder may suffer and how this fact can harm different aspects of their life and finding ways to combat it is also to avoid consequences that harm the common good.

Long-term changes on behavioral addictions symptoms among adults with attention deficithyperactivity disorder treated withmethylphenidate.

Attention deficit hyperactivity disorder (ADHD) and behavioral addictions (BAs) are highly comorbid but little is known about the effect of anti-ADHD medications on behavioral addiction symptoms. Thus, the aim of this naturalistic prospective study was to investigate the long-term changeson BAs symptoms among methylphenidate-treated adults with a primary diagnosis of ADHD. 37 consecutive adult ADHD outpatients completed a baseline and follow-up assessment of ADHD, mood and BAs symptoms (internet, shopping, food, sex addictions and gambling disorder) after one year of methylphenidate (flexible dose) treatment. Internet addiction test scores pre-treatment were significantly higher than post-treatment scores (p < 0.001). The same trend was seenfor the shopping addiction (p = 0.022), food addiction scores (p = 0.039) and sex addiction scores (p = 0.047). Gambling disorder scores did not differ pre and post treatment since none of the included patients reported significant gambling symptoms at baseline. The rate of ADHD patients with at least one comorbid BA was reduced after methylphenidate treatment (51.4% vs 35.1%). The correlation analyses showed a moderate positive correlation between the changes in sluggish cognitive tempo symptoms, cognitive impulsivity, mood and anxiety symptoms and changes in internet addiction symptoms. This is the first study showing that after one-year of treatment with methylphenidate,adult ADHD patients show a significant reduction on internet, food, shopping and sex addiction symptoms. Further controlled studies with larger samples should replicate these preliminaryresults and elucidate the role of methylphenidate and other moderator factors (such as concomitant psychological treatments or lifestyle habits changes) on BAs improvements.

Self-rated costs and benefits of conventional and alternative adult ADHD treatments.

Conventional treatments offered by healthcare providers for adult ADHD include pharmacological and non-pharmacological approaches or a combination of both. Both treatment types may have downsides like side effects or low efficacy, potentially leading to treatment dissatisfaction. Also, adults with ADHD explore non-prescribed, complementary and/or alternative medicine (CAM) on their initiative, including substances such as dietary supplements and activities such as physical exercise. This survey study aimed to investigate the types of conventional and CAM treatments adults with ADHD use and their self-rated effectiveness. Also, lifetime experience of negative effects across all treatment types and the motives to use CAM were explored. In total, 227 adults diagnosed with ADHD or reporting clinically elevated ADHD symptoms (without official ADHD diagnosis) were included in the analyses. Both lifetime and current use and experiencing negative effects were highest for conventional pharmacological treatments, followed by CAM activities, CAM substances, and conventional non-pharmacological approaches. The most common reason for using CAM was overall well-being. Conventional treatments were rated more effective in influencing cognition than CAM, but their self-rated effectiveness did not differ in other assessed domains. CAM activities were rated more effective than CAM substances in all assessed domains. This study highlights the high prevalence of CAM use by adults with ADHD, implying that some patients find value in such alternative treatments. Future studies should consider investigating alternative and/or complementary treatments for adult ADHD, alone or in combination with conventional treatments.

The complex clinical and cognitive phenotype of adult patients with attention deficit hyperactivity disorder (ADHD) and comorbid hoarding disorder

Objectives Several studies consistently showed that patients with attention deficit hyperactivity disorder (ADHD) have high rates of hoarding disorder (HD) comorbidity. The aim of the present study was to compare the clinical and cognitive features of adult ADHD patients with and without hoarding comorbidity according to a self-report measure, and a sample of healthy controls. Methods Fifty-seven consecutive adult outpatients with a primary diagnosis of ADHD with comorbid hoarding disorder (ADHD+HD), 57 matched ADHD patients without hoarding disorder comorbidity (ADHD-HD), and a control group of 47 healthy controls (HCs) were enrolled. All subjects undergone a comprehensive clinical assessment and a neurocognitive assessment focused on attention, memory, and executive functions. Results The ADHD groups differed on most of the clinical and cognitive measures compared to HCs. ADHD+HD patients showed similar ADHD symptoms but greater subjective impulsivity, mood and anxiety symptoms, and a greater functional impairment compared to ADHD-HD patients as well as greater attentional and executive functioning impairments. Conclusions ADHD patients with comorbid hoarding disorder present a more complex clinical and neuropsychological phenotype correlated to a greater functional impairment compared to ADHD patients without this comorbidity. These results further highlight the relevance of assessing and treating hoarding behaviours in adults with ADHD.

Associations between ADHD symptoms, executive function and frontal EEG in college students

Introduction This study aims to assess whether electroencephalogram (EEG) spectral power change scores (e.g. task spectral power subtracted from resting state spectral power) across three different frequency bands, alpha (8–12 Hz), theta (4–7 Hz), and beta (13–30 Hz), predicts self-reported attention-deficit hyperactivity disorder (ADHD) symptoms using the Adult ADHD Self-Report Scale (ASRS) over and above self-reported executive function (EF) abilities using the Behavior Rating Inventory of Executive Function (BRIEF-A) Global Executive Composite (GEC) T-scores for adults. Methods Data were collected at a rural, mid-sized southeastern university (N = 52) and participants received course credit for participation. Participants self-reported ADHD symptoms and EF abilities before completing eyes open resting state and the attention network test (ANT), a common flanker task that measures ability to orient attention, stay alert, and resolve conflict (i.e. distractor arrows) while recording EEG spectral power at electrodes F3 and F4. Bivariate correlations determine associations between EEG measures and self-reported ADHD symptoms and EF abilities. Linear regressions were used to assess whether EEG change scores were predictive of ADHD symptoms over and above EF abilities. Results High correlation coefficients were found only when comparing the ASRS and BRIEF-A GEC T-scores (r = .822, p <.001). Regression analyses produced significant results indicating EEG spectral change scores were predictive of ADHD symptoms, over and above GEC T-Scores, for the alpha band but not the theta and beta bands. Additionally, we found an inverse relationship when comparing change scores in the alpha band across the right (F4) and left (F3) hemispheres supporting the theory of frontal asymmetry for individuals with increased ADHD symptoms. Conclusion This study is the first to assess the predictive ability of EEG spectral power change scores in predicting ADHD symptoms, which are not solely explained by deficits in executive control. Past research has indicated significant differences when comparing task and resting state spectral power indicating change scores might have some utility in measuring cognitive load, specifically in the alpha band, which has been associated with inhibition, working memory, and anticipation of stimuli. Further research should be conducted to assess the utility change scores might have in providing an objective measure related to a clinical population with ADHD.

Prevalence of Adult Attention Deficit Hyperactivity Disorder among Medical Students, King Faisal University

Background: The neurobehavioral disorder known as attention-deficit/hyperactivity disorder (ADHD) is typified by impulsivity, hyperactivity, and difficulty in maintaining focus. According to recent research, it can last into adulthood. Regarding identifying adult ADHD, the fifth edition of the "Diagnostic and Statistical Manual of Mental Disorders" has undergone major alteration. As far as we are aware, few research has been done in the Gulf region on adult ADHD among medical students.Method: A cross-sectional study was carried out on students of medicine from all academic years in King Faisal University, Hofuf, from December 2023 until June 2024. 279 medical students participated in the study. Self-reported English questionnaires with two sections—a sociodemographic section and a screening scale for adult ADHD based on the DSM5 version—were utilized for the investigation. Outcomes: (14. %) of pupils mentioned having signs of ADHD. Results: Of the sample, 14% of students exhibited ADHD symptoms, a rate higher than the global prevalence. Female students (13.1%) and first-year students (18.9%) showed significant ADHD symptoms. Psychological comorbidities were present in 28.6% of ADHD-affected students compared to 11.4% of non-affected students. The ADHD group demonstrated mild but notable challenges in concentration, relaxation, and impulsive behavior, with implications for academic performance and stress management.Conclusion: Our study shows a higher prevalence compared with a worldwide prevalence of i.e., 14%. This difference could be due to community interaction and way of living life style factors. Those individuals may have difficulty in communication and learning which can disturb students’ academic efficiency, lengthen their study, and even disturb their development.

Exploring the impact of probiotics on adult ADHD management through a double-blind RCT.

Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric condition often persisting into adulthood, characterized by inattention, impulsivity, and hyperactivity. Emerging research suggests a connection between ADHD and gut microbiota, highlighting probiotics as potential therapeutic agents. This study involved a double-blind, randomized controlled trial where college students with ADHD received either a multi-strain probiotic supplement or a placebo daily for three months. ADHD symptoms were evaluated using a computerized performance test (MOXO) and the MATAL questionnaire. Academic records provided performance data. Additionally, eating and sleeping habits, gastrointestinal symptoms, and anthropometrics were assessed through questionnaires before and after the intervention. Fingernail cortisol concentrations (FCC) measured the long-term activity of the hypothalamic-pituitary-adrenal axis. The findings indicated that the probiotic significantly decreased hyperactivity, improved gastrointestinal symptoms, and enhanced academic performance. A multivariate analysis identified age as a significant predictor, with younger participants experiencing greater overall benefits from the intervention. There was also a negative correlation between FCC and symptoms of attention and impulsivity. Furthermore, higher academic grades were associated with lower levels of hyperactivity and impulsivity. These results suggest a beneficial impact of probiotics on ADHD symptoms and lay the groundwork for further studies to evaluate the effects of various probiotic strains on clinical outcomes in ADHD.

Identifying Factors that Increase False-Positive Rates on Embedded Performance Validity Testing in ADHD Evaluations.

This study investigated why certain embedded performance validity indicators (EVIs) are prone to higher false-positive rates (FPRs) in attention-deficit/hyperactivity disorder (ADHD) evaluations. The first aim was to establish the relationship between FPRs and 15 EVIs derived from six cognitive tests when used independently and together among adults with ADHD who have valid test performance. The second aim was to determine which specific EVIs increase the FPRs in this population. Participants were 517 adult ADHD referrals with valid neurocognitive test performance as determined by multiple performance validity tests and established empirical criteria. FPRs were defined by the proportion of participants who scored below an empirically established EVI cutoff with ≥0.90 specificity. EVIs derived from two of the six tests exhibited unacceptably high FPRs (>10%) when used independently, but the total FPR decreased to 8.1% when the EVIs were aggregated. Several EVIs within a sustained attention test were associated with FPRs around 11%. EVIs that did not include demographically adjusted cutoffs, specifically for race, were associated with higher FPRs around 14%. Conversely, FPRs did not significantly differ based on whether EVIs included timed versus untimed, verbal versus nonverbal, or graphomotor versus non-graphomotor components, nor whether they had raw versus standardized cut scores. Findings suggest that practitioners should consider both the type of test from which an EVI is derived and the aggregate number of EVIs employed to minimize the FPRs in ADHD evaluations. Findings also indicate that more nuanced approaches to validity test selection and development are needed.

Asymmetry of attentive networks contributes to adult Attention-deficit/hyperactivity disorder (ADHD) pathophysiology.

Diffusion imaging studies in Attention-deficit/hyperactivity disorder (ADHD) have revealed alterations in anatomical brain connections, such as the fronto-parietal connection known as superior longitudinal fasciculus (SLF). Studies in neurotypical adults have shown that the three SLF branches (SLF I, II, III) support distinct brain functions, such as attention and inhibition; and that their pattern of lateralization is associated with attention performance. However, most studies in ADHD have investigated the SLF as a single bundle and in children; thus, the potential contribution of the lateralization of the SLF branches to adult ADHD pathophysiology remains to be elucidated. We used diffusion-weighted spherical deconvolution tractography to dissect the SLF branches in 60 adults with ADHD (including 26 responders and 34 non-responders to methylphenidate, MPH) and 20 controls. Volume and hindrance modulated orientational anisotropy (HMOA), which respectively reflect white matter macro- and microstructure, were extracted to calculate the corresponding lateralization indices. We tested whether neurotypical controls differed from adults with ADHD, and from treatment response groups in sensitivity analyses; and investigated associations with clinico-neuropsychological profiles. All the three SLF branches were lateralized in adults with ADHD, but not in controls. The lateralization of theSLFI HMOA was associated with performance at the line bisection, not that of the SLF II volume as previously reported in controls. Further, an increased left-lateralization of the SLF I HMOA was associated with higher hyperactivity levels in the ADHD group. Thus, an altered asymmetry of the SLF, perhaps especially of the dorsal branch, may contribute to adult ADHD pathophysiology.

Working memory related functional connectivity in adult ADHD and its amenability to training: A randomized controlled trial

BackgroundWorking memory (WM) deficits are among the most prominent cognitive impairments in attention deficit hyperactivity disorder (ADHD). While functional connectivity is a prevailing approach in brain imaging of ADHD, alterations in WM-related functional brain networks and their malleability by cognitive training are not well known. We examined whole-brain functional connectivity differences between adults with and without ADHD during n-back WM tasks and rest at pretest, as well as the effects of WM training on functional and structural brain connectivity in the ADHD group. MethodsForty-two adults with ADHD and 36 neurotypical controls performed visuospatial and verbal n-back tasks during functional magnetic resonance imaging (fMRI). In addition, seven-minute resting state fMRI data and diffusion-weighted MR images were collected from all participants. The adults with ADHD continued into a 5-week randomized controlled WM training trial (experimental group training on a dual n-back task, n = 21; active control group training on Bejeweled II video game, n = 21), followed by a posttraining MRI. Brain connectivity was examined with Network-Based Statistic. ResultsAt the pretest, adults with ADHD had decreased functional connectivity compared with the neurotypical controls during both n-back tasks in networks encompassing fronto-parietal, temporal, occipital, cerebellar, and subcortical brain regions. Furthermore, WM-related connectivity in widespread networks was associated with performance accuracy in a continuous performance test. Regarding resting state connectivity, no group differences or associations with task performance were observed. WM training did not modulate functional or structural connectivity compared with the active controls. ConclusionOur results indicate large-scale abnormalities in functional brain networks underlying deficits in verbal and visuospatial WM commonly faced in ADHD. Training-induced plasticity in these networks may be limited

Who transitions to bipolar disorder? A comparison of major depressive disorder, anxiety, and ADHD

BackgroundDiagnostic delays in Bipolar Disorder (BD) are common and can contribute to worse outcomes. While most studies focus on depression as a primary precursor, both anxiety and attention deficit disorders are also frequent initial diagnoses. In the current study, we utilized a large, diverse electronic health record (EHR) dataset to quantify the rates and correlates of conversion to BD from these major precursor diagnoses. MethodsOur study analyzed a comprehensive ten-year EHR dataset from Johns Hopkins Medicine, a diverse urban medical center, to assess and compare the rates and correlates of conversion to BD from Major Depressive Disorder (MDD), anxiety disorders, and ADHD. Risk factors for transition were assessed as time-varying variables in proportional hazards models. ResultsOf the 21,341 patients initially included, 1232 later transitioned to a diagnosis of BD. Adjusted-one-year conversion rates for patients with MDD, anxiety disorders, and ADHD were 4.2 %, 3.4 %, and 4.0 %, respectively, with ten-year rates at 11.4 %, 9.4 %, and 10.9 %, respectively. Age (19–29 years), treatment setting (emergency and inpatient), and psychotropic medications were associated with conversion to BD across all precursor diagnoses. Severe and psychotic forms of MDD were among the strongest risk factors for transitioning to BD. Although transition rates were lower in children, risk factors were similar, with the exception of ADHD, which showed a stronger association with BD conversion in adults. ConclusionsThe highest risk of transitioning to BD was observed in patients initially diagnosed with MDD, though significant risk was also noted in those with initial diagnoses of anxiety disorders and adult ADHD.

Assessing suicidality in adult ADHD patients: prevalence and related factors

BackgroundThe association between Attention-deficit hyperactivity disorder (ADHD) and suicidality has been subject of growing interest for research in the latest years. Suicidality was generally assessed categorically and without the use of validated instruments, leading to heterogeneous or even conflicting evidence. The prevalence of both suicidal ideation and attempts varies considerably, and the associated risk factors remain unclear. Our study investigated suicidality in ADHD using a dimensional approach and a validated and internationally recognized instrument. Our primary aim was to evaluate the prevalence of suicidal ideation (SI), severe suicidal ideation (SSI), suicidal behavior (SB) and non suicidal self-injury behavior (NSSIB) in a sample of adult patients with ADHD. The second objective was to identify sociodemographic and clinical features associated with increased risk of suicidality in these patients.MethodsThe sample included 74 adult patients with clinical diagnosis of ADHD. Suicidality was assessed by administering the Columbia-Suicide Severity Rating Scale. Logistic regressions were used to examine predictors of SI, SSI, SB and NSSIB.ResultsThe lifetime prevalence of SI and SSI were 59.5% and 16.2%, respectively. The 9.5% of patients showed lifetime SB, while NSSIB was found in 10.8% of the subjects. Lifetime SI was associated with severity of inattentive symptoms during adulthood, low self-esteem and impairment in social functioning. Lifetime SSI appeared related to severity of inattentive symptoms during childhood, attentional impulsiveness and number of hospitalizations, while physical activity appeared to be protective. The prevalence of lifetime SB and NSSIB did not appear significantly related to any socio-demographic or clinical feature.ConclusionsAdults with ADHD should be considered at risk of suicide and it is important to determine which patients are at higher risk, in order to guide preventive interventions. The association between ADHD and suicidal ideation did not appear to be influenced by psychiatric comorbidities, but rather by inattention itself, which represents the core symptom of ADHD.

Focus on Executive Functions. Part 2: Nonverbal and Verbal Working Memory

The second in a 3-part series on executive functions. This series for adults with ADHD discusses the 7 executive functions that foster self-control—the abilities we use to monitor our own behavior to attain our goals. —Excerpted from Taking Charge of Adult ADHD (2nd ed.), by Russell A. Barkley with Christine M. Benton. Part 1: Self-awareness (the mind's mirror) and inhibition (the mind's brakes). Part 2: Nonverbal and verbal working memory (the mind’s eye and the mind’s voice). Part 3: Emotion regulation (the mind’s heart), self-motivation (the mind’s fuel tank), and planning/problem-solving (the mind’s playground).

성인 ADHD 어머니의 자녀양육 경험에 대한 내러티브 탐구

Objectives This study conducted a narrative inquiry to explore the difficulties of parenting experience as an adult ADHD mother, the experiences and meanings of life of participants, and to help them understand life. Methods To this end, one adult ADHD mother was selected as a participant, and 6-8 in-depth interviews were conducted from May 2023 to February 2024. The research procedure applied the five steps suggested by Clandinin and Connelly (2000): being present in the field, moving to the field text, constructing the field text, constructing meaning for the experience, and constructing the research text. Results The results of the child-rearing experiences of mothers with adult ADHD tendencies derived with the study participants are as follows. There were five themes: ‘No one taught me emotions’, ‘Pushing me to the end’, ‘Walking with hands’, and ‘The path to becoming solid- Becoming a mom who takes notes’. Conclusions Based on these results, suggestions for counseling were discussed in the context of personal justifi-cation ‘looking back on myself’, actual justification ‘Knowing but not being able to control it’, and social justification ‘growing together- spring again’, and the significance of the study and suggestions for follow-up research were made.

Using Bifactor Twin Modeling to Assess the Genetic and Environmental Dimensionality of Adult ADHD Symptoms.

Attention Deficit Hyperactivity Disorder (ADHD) is a common and heritable neurodevelopmental condition that has been the subject of a wealth of genetics research. Because ADHD has an early age of onset, most of this work has focused on children, meaning that less is known about the genetics of ADHD in adults. Additionally, while much research has assessed the heritability of ADHD as a general dimension, less has assessed the heritability of individual subtypes (inattention, hyperactivity) or symptoms of ADHD. It therefore remains unclear whether the genetic factors underlying ADHD symptoms conform to a unidimensional or multidimensional structure. The aim of this study was to assess the genetic and environmental dimensionality of adult ADHD symptoms. We analyzed data from 10,454 twins of the Twins Early Development Study, who provided self-reports of ADHD symptoms using the Conners scale at age 21 years. The data conformed well to a psychometric bifactor model, providing support for a general dimension of ADHD in addition to secondary dimensions for inattention and hyperactivity. However, a bifactor independent pathway twin model provided support for a general dimension only at the level of non-shared environmental effects and not additive genetic or shared environmental effects. This suggests that symptoms of ADHD cluster together under a general dimension of non-shared environmental effects, although the two subtypes of ADHD (inattention and hyperactivity) are meaningfully genetically distinct. We found the overall heritability of ADHD to be 40%, comparable with previous estimates for adult ADHD symptoms. Our results provide useful insights into the genetic and environmental architecture of specific ADHD symptoms.

Gambling disorder and its associated factors in university students

Abstract Background Gambling disorder (GD) is defined as persistent and uncontrollable gambling behaviour that has negative effects on an individual’s life. This can lead to financial problems, poor academic performance, and health problems. GD has been associated with psychological disorders like depression, anxiety, and attention-deficit hyperactivity disorder (ADHD). We aimed to examine the gambling disorder and its associated factors in university students. Methods We conducted a cross-sectional study among students at a university in Eskisehir (Türkiye) in 2024. A stratified random sample design was used. Five faculties were randomly selected. A total of 1,201 students were included according to the stratum weight of the faculties. A questionnaire including sociodemographic characteristics, South Oaks Gambling Screen (SOGS), and Adult ADHD Self-Report Scale (ASRS) was applied. Data were analysed through descriptive statistical analyses and multivariate logistic regression models. Results The mean age was 21.5±2.8 years, and 46.8% were male. While 48.7% of the students stated that they had gambled at least once, 2.2% had a gambling disorder. The three most common types of gambling played by students were stock market (28.2%), bet on sports (22.0%), and scratch cards (18.2%). In multivariate analysis, being male (Odds ratio-OR:6.5, 95%CI:1.4-29.8), having lost years during education (OR:2.7, 1.1-6.8), having relatives with gambling problems (OR:8.0, 1.8-36.2), investing greater amounts of money in gambling (OR:3.7, 1.0-13.0), and having a high probability of ADHD (OR:4.3, 1.4-12.8) were found to be predictors for GD. Conclusions Although about half of the students had engaged in gambling activities, only a small proportion showed signs of GD. We can conclude that being male, having lost years in education, having relatives with gambling problems, investing larger amounts of money in gambling, and having a higher probability of ADHD are predictors of GD among students. Key messages • Implementing educational campaigns at universities to raise awareness of the potential risks and consequences associated with GD could be beneficial. • It may be helpful if mental health services at the university were equipped to consider mental health conditions such as ADHD, that contribute to GD.

Diagnosing and Treating ADHD in Adults

This Viewpoint advocates for proactively addressing concerns related to the diagnosis and treatment of attention-deficit/hyperactivity disorder (ADHD) in US adults to balance individual benefits with population-level risk.

An investigation of the Bernstein’s strengths Scale: factorial validity and network analysis of attention-deficit/hyperactivity symptoms, mental health, and the strengths of the healthy adult self

BackgroundBernstein’s heuristic model of personal strengths describes 16 positive attributes of the healthy adult self, grouped into four higher-order factors: self-directedness (identity, self-reflection, self-confidence, self-assertion, imagination/creativity), self-regulation (emotional balance, resilience, self-control, self-care, reality testing), connection (empathy, compassion, humour, responsibility), and transcendence (gratitude and wisdom). The study aimed to explore the factorial validity of Bernstein’s Strengths Scale developed for the assessment of these constructs. Furthermore, we explored the association of strengths with attention-deficit hyperactivity (ADHD) symptoms and mental health in a nonclinical sample using a network approach.MethodsFive hundred and twenty-eight adults filled out an online questionnaire, including Bernstein’s Strengths Scale (BSS), the Mental Health Continuum – Short Form (MHC-SF), and the Adult ADHD Self-Report Scale (ASRS).ResultsThough our data showed an acceptable fit to the 16-factor model, the Self-control subscale and item 28 of the Compassion subscale were excluded because of reliability issues. The final model with 15 factors and 44 items showed excellent fit, χ2(797) = 1130.149, p < .001, RMSEA = 0.028, 90% CI [0.024, 0.032], SRMS = 0.049, CFI = 0.993, TLI = 0.991. Principal component analysis revealed three instead of four second-order factors. In the network model, Self-confidence and Wisdom emerged as the most influential nodes. ADHD symptoms were negatively connected to Responsibility, Self-care, Identity, Emotional balance, Self-confidence, and mental health, while they had positive edges with Humor, Self-reflection, and Imagination/creativity. Mental health was positively related to several strengths, with the strongest association being between mental health and Gratitude.ConclusionThe BSS has acceptable factorial validity and is a reliable tool for assessing the personal strengths of the healthy adult self. ADHD symptoms in adults may be associated with deficits in personal strengths, but protective factors could also be identified. Addressing personal strengths in psychosocial interventions for ADHD in adults may improve patients’ emotional well-being and everyday functioning.

Executive functioning in adults with attention deficit hyperactivity disorder: A systematic review

Introduction: Executive function deficits are associated with attention deficit hyperactivity disorder (ADHD) in both children and adults. The inattentive subtype is primary related to “cold” executive functions, while the hyperactive subtype is related to “warm” executive functions. Objective: To systematically review studies on executive functioning in adults with attention deficit hyperactivity disorder published during the last decade. Methodology: A documentary research was conducted, encompassing 33 articles retrieved from PubMed, Web of Science and EBSCO platforms. The analysis considered years and countries of publication, attention deficit hyperactivity disorder diagnostic criteria, participants, comorbidities, subtypes, medication use, assessment tools, and processes of executive functions evaluated. Results: It was evidenced that there is a high percentage of adults with attention deficit hyperactivity disorder who present a deficit or lower performance in executive function tests. However, the results varied depending on specific characteristics of the study and/or participants, which confirms the heterogeneity of the disorder. In addition, the main instruments for measuring executive functions and diagnostic criteria for adult attention deficit hyperactivity disorder were identified. Discussion: These results support the established links between attention deficit hyperactivity disorder , impaired executive functions, and major life activities found in the adult attention deficit hyperactivity disorder literature. However, some of the limitations were the poorly controlled variables such as comorbidities, attention deficit hyperactivity disorder subtypes that were not assessed, and usage of instruments that measure executive functions that can lead to reduced credibility of the results presented here. Conclusions: According to the results presented, there is a high percentage of adults with attention deficit hyperactivity disorder who present a deficit or lower performance in executive function tests, compared to both neurotypical adults and those with other psychiatric disorders. Further research is recommended to continue studies on the topic and to include other variables.

Examining the utility of the BAARS-IV scales as embedded symptom validity indicators for adult attention-deficit/hyperactivity disorder evaluations

Objective: This study investigated whether extreme cut-scores on the Barkley Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale-Fourth Edition (BAARS-IV) self-report scales could serve as symptom overreporting indicators in adult ADHD evaluations. Method: The sample consisted of 162 adults who underwent a neuropsychological evaluation for ADHD. Patients were classified into valid (n = 115) and invalid (n = 47) groups based on multiple criterion symptom validity tests. Results: Overreporting cut-scores identified for each of the BAARS-IV scales demonstrated acceptable classification accuracy or better. The Current Total scale yielded the highest classification accuracy (area under the curve of .83). An optimal raw cut-score of ≥56 for this scale yielded 47% sensitivity when upholding ≥90% specificity. A cut-score of ≥31 for the Current Inattention scale (90% specificity; 47% sensitivity) and ≥29 for the Current Sluggish Cognitive Tempo scale (88% specificity; 46% sensitivity) were also relatively strong indicators of overreporting. The Current Total and Current Sluggish Cognitive Tempo scales captured nonredundant aspects of symptom validity, and using them together increased sensitivity to 57% while maintaining ≥90% specificity. Conclusions: Findings provide preliminary support for the criterion and construct validity of extreme cut-scores on the BAARS-IV Current Sluggish Cognitive Tempo, Current Inattention, and Current Total scales as indicators of ADHD symptom overreporting. However, employing the cut-scores from the Current Sluggish Cognitive Tempo (≥29) and Current Total (≥56) together may be the most promising way to detect overreporting. Scores above both of these cut-points should, at a minimum, prompt further investigation into the validity of a patient’s reported symptoms.
