Background. Several theoretical explanations of ADHD in children have focused on executive functioning as the main explanatory neuropsychological domain for the disorder. In order to establish if these theoretical accounts are supported by research data for adults with ADHD, we compared neuropsychological executive functioning and non-executive functioning between adults with ADHD and normal controls in a meta-analytic design.Method. We compared 13 studies that (1) included at least one executive functioning measure, (2) compared the performance of an adult ADHD group with that of an adult normal control group, (3) provided sufficient information for calculation of effect sizes, and (4) used DSM-III-R or DSM-IV criteria to diagnose ADHD.Results. We found medium effect sizes both in executive functioning areas [verbal fluency (d=0·62), inhibition (d=0·64 and d=0·89), and set shifting (d=0·65)] and in non-executive functioning domains [consistency of response (d=0·57), word reading (d=0·60) and color naming (d=0·62)].Conclusions. Neuropsychological difficulties in adult ADHD may not be confined to executive functioning. The field is in urgent need of better-designed executive functioning tests, methodological improvements, and direct comparisons with multiple clinical groups to answer questions of specificity.

AbstractStigmatization represents a major barrier to treatment seeking across mental disorders. Despite this, stigma research on individual mental disorders remains in its infancy. Attention-deficit hyperactivity disorder (ADHD) in adults also represents an under-researched area—being far less studied than its child counterpart. This study examined the current state of public perceptions towards adult ADHD. A simulation group consisting of 105 participants performed the Weiss Functional Impairment Rating Scale (WFIRS) and Conners’ Adult ADHD Rating Scales (CAARS) as though they had ADHD. These scores were compared to a group consisting of 98 individuals with adult ADHD and a group of 117 healthy individuals both groups being instructed to complete the WFIRS and CAARS to the best of their abilities. Simulators were found to overestimate impairments in adult ADHD (to a large effect) in the domains of hyperactivity, DSM-IV hyperactivity-impulsivity, DSM-IV total, work, school, (to a medium effect) in family and social, and (to a negligible-small effect) in inattention, impulsivity, DSM-IV inattention, and life skills when compared to the ADHD group, and in all domains (to a large effect) when compared to the control group. Current and retrospective ADHD symptoms were found to be associated with more accurate perceptions in a number of domains. Evidence for the presence of perceptions considered to be stigmatizing was found, with largest effects present in the domains of hyperactivity, impulsivity, impairments at work, school, and engagement in risky behaviour.

This study aimed to examine cognitive factors associated to food addiction (FA) symptoms in a non-clinical sample of adolescents. A group of 25 adolescents (12–18 years; Mean age = 15.2 years) with a high level of FA symptoms (two and more) were compared to a control group without FA symptoms (n = 25), matched on sex and age, on four Cambridge Neuropsychological Test Automated Battery (CANTAB) neuropsychological tasks (MT: Multitasking Test; OTS: One Touch Stockings of Cambridge; SST: Stop Signal Task; RVP: Rapid Visual Information Processing). They were also compared on self-reported questionnaires assessing binge eating, depressive and anxiety symptoms, impulsivity levels, as well as executive functioning difficulties. Group comparisons did not show significant differences on neuropsychological tasks’ performances. However, effect sizes’ estimates showed small to medium effect sizes on three scores: adolescents with a high level of FA symptoms showed a higher probability of an error following an incorrect answer (OTS), a higher probability of false alarm, and a poorer target sensitivity (RVP). When referring to self-reported measurements, they reported significantly more executive functioning difficulties, more binge eating, depressive symptoms and higher impulsivity levels. Overall, results suggested that cognitive difficulties related to FA symptoms seem to manifest themselves more clearly when assessing daily activities with a self-reported questionnaire, which in turn are strongly related to overeating behaviors and psychological symptoms. Future longitudinal research is needed to examine the evolution of those variables, their relationships, and contribution in obesity onset. More precisely, the present findings highlighted the importance of affective difficulties related to this condition, as well as the need to take them into account in its assessment.

Here, we developed and examined a new way of disseminating mindfulness in nature to people without meditation experience, based on the finding that mindfulness conducted in natural settings may have added benefits. We evaluated a 5-day residential programme aiming to reduce stress and improve mental health outcomes. We compared an indoor and an outdoor version of the programme to a control group in a pilot randomised controlled trial (RCT). Sixty Danish university students experiencing moderate to high levels of stress were randomised into a residential mindfulness programme indoors (n = 20), in nature (n = 22), or a control group (n = 18). Participants completed the Perceived Stress Scale and the Self-Compassion Scale (primary outcomes) along with additional secondary outcome measures at the start and end of the program and 3 months after. Stress was decreased with small to medium effect sizes post-intervention, although not statistically significant. Self-compassion increased post-intervention, but effect sizes were small and not significant. At follow-up, changes in stress were not significant, however self-compassion increased for both interventions with medium-sized effects. For the intervention groups, medium- to large-sized positive effects on trait mindfulness after a behavioural task were found post-intervention, and small- to medium-sized effects in self-reported mindfulness were seen at follow-up. Connectedness to Nature was the only outcome measure with an incremental effect in nature, exceeding the control with a medium-sized effect at follow-up. All participants in the nature arm completed the intervention, and so did 97% of the participants in all three arms. Overall, the results encourage the conduct of a larger-scale RCT, but only after adjusting some elements of the programme to better fit and take advantage of the potential benefits of the natural environment.

Objective: This work assesses family functioning, parental bonding, and the relationship between the two in adults diagnosed with ADHD. Method: The study used a retrospective, ex post facto design and consisted of 100 adult participants, who were distributed into two groups: with and without diagnosis of ADHD. Two family assessment instruments were applied: the Family Adaptability and Cohesion Evaluation Scale short spanish version (FACES-20esp)) and the Parental Bonding Instrument (PBI). The diagnosis of ADHD was done by using a semistructured interview for Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria (Conners’ Adult ADHD Diagnostic Interview for DSM-IV [CAADID]). Results: The results showed that higher rigidity and lower emotional connection were significantly associated with ADHD family functioning. Regarding parental bonding, the results showed significant differences only in the care dimension, with the ADHD group reporting lower care than the control group. Conclusion: The results suggest that ADHD families present dysfunctional family functioning with a rigid, separated typology, and parental bonding based on control without affection.

AbstractObjectives: Children and adolescents with moderate-to-severe traumatic brain injury (TBI) present with short and long-term neuropsychological deficits following their injury. The aim of this study was to investigate the utility of a brief computerized test battery for evaluating cognitive functioning sub-acutely following a TBI. Methods: Participants (n=33) sustained a moderate-to-severe TBI, were between 8 and 18 years old, and were assessed using CNS Vital Signs (CNSVS) within 6 months post-injury (median=0.6 month). Participants with TBI were matched to 33 healthy controls based on age, sex, and handedness to compare their cognitive functioning on the CNSVS battery. Results: Children and adolescents with moderate-to-severe TBI had significantly lower scores and large effect sizes on Reaction Time, Complex Attention, and Cognitive Flexibility domains, as well as medium effect sizes on two Visual Memory test scores and one Psychomotor Speed test score. A significantly higher percentage of participants with TBI had cognitive impairment on Reaction Time domain score compared to the control group. Finally, CNSVS domain scores correctly categorized 76% of participants as either group with TBI or control group. Conclusions: CNSVS may be a useful tool for screening cognitive abilities in children and adolescents who are early in their recovery from a moderate-to-severe TBI, particularly when a rapid screening evaluation can help guide management, interventions, and track recovery.

Abstract Background: Our study aimed to understand the effects of HIV and cocaine dependence (CD) on discrete aspects of executive functioning via the Stroop Color-Word Test and the Trail Making Test (TMT). We recruited 101 participants (26 HIV+/CD+; 18 HIV+/CD-; 30 HIV-/CD+; and 27 HIV-/CD-. Methods: We utilized a series of 2 (HIV: yes/no) × 2 (Cocaine: yes/no) ANCOVA’s while controlling for age and premorbid intelligence on the Stroop trials (i.e., color-naming, word reading, interference), and ANOVA’s were used to test for group differences on TMT-A and TMT-B z-scores, the number of errors, and the B/A ratio score. Results: We found a significant main effect of HIV on the Stroop Interference (p = 0.012) and the TMT B/A ratio (p = 0.017), these findings are consistent with difficulties in cognitive flexibility. On the Color-Naming and Interference trials, individuals with CD made significantly more errors than non-users (p = 0.028), demonstrating difficulties with inhibition. Conclusions: Our results show HIV and CD are associated with different underlying cognitive processes which impact overall executive functioning. Understanding the different cognitive factors impacting executive functioning can help formulate tailored treatment recommendations and targeted interventions for people living with HIV and those with cocaine dependence.

BackgroundTo examine the association between psychological tests of executive functioning and functional outcomes among high-IQ adults with attention deficit hyperactivity disorder (ADHD).MethodSubjects were high-IQ adults with (n=64) and without ADHD (n=53). Subjects were administered a battery of neuropsychological tests assessing executive functioning.ResultsHigh-IQ adults with ADHD performed less well than those without ADHD on several psychological tests of executive functioning, including the Wisconsin Card Sorting Test (WCST), Stroop Color and Word Test, Rey–Osterrieth Complex Figure Test (ROCF), California Verbal Learning Test (CVLT) and an auditory continuous performance test (CPT). Test performance in the high-IQ adult ADHD group, however, was average. In the entire sample, performance on several tests of executive functioning including the ROCF and the CVLT were significant predictors of real-world functioning.ConclusionsHigh-IQ adults with ADHD perform less well on tests of executive functioning relative to high-IQ control participants. Performance on several tests of executive functioning was a significant predictor of functioning.

Career commitment refers to one’s emotional attachment to one’s career rather than to one’s current working organization. While career commitment has been studied for decades as an important construct in applied psychology research, robust conclusions about its antecedents have not been drawn by empirical research. To address this issue, this research presents the results of a meta-analytic review of the antecedents of career commitment based on data from 156 individual studies (N = 58,651) conducted between 1980 and 2019. A total of 52 latent antecedents were captured and categorized into five different groups, and the strength, direction and heterogeneity of the relations between career commitment and its antecedents were meta-analytically investigated. Our findings revealed that while individual attributes (e.g. age) alone were weak predictors of career commitment, psychological (e.g. job satisfaction) and organizational factors (e.g. organizational career growth) exhibited medium effect sizes. In addition, among job-related factors, autonomy demonstrated a relatively strong influence on career commitment. The implications are elucidated for researchers and practitioners in the light of these key findings.

There is considerable debate about whether bilingual children are advantaged in executive functioning relative to monolingual children. The current meta-analysis addressed this debate by comprehensively reviewing the available evidence. Here, we synthesized data from published studies and unpublished datasets, which equated to 1209 effect sizes from 10,672 bilingual and 12,289 monolingual participants aged 3- to 17-years. Consistent with the bilingual advantage hypothesis, bilingual language status had a small effect on children’s executive functions (g =.08, 95% CI [.01, .14]). However, this effect was indistinguishable from zero after adjusting for bias (g=-.04, 95 % CI [-.12, .05]). Further, no significant effects were apparent within the executive attention, where the effects of language status are thought to be most pronounced (g =.08, 95% CI [.01, .14]). Results, therefore, suggest that the bilingual advantage in children’s executive control is small, variable, and potentially not attributable to the effect of language status.

Children and adolescents are a vulnerable group to develop post-traumatic stress symptoms after natural or man-made disasters. In the light of increasing numbers of refugees under the age of 18 years worldwide, there is a significant need for effective treatments. This meta-analytic review investigates specific psychosocial treatments for children and adolescents after man-made and natural disasters. In a systematic literature search using MEDLINE, EMBASE and PsycINFO, as well as hand-searching existing reviews and contacting professional associations, 36 studies were identified. Random- and mixed-effects models were applied to test for average effect sizes and moderating variables. Overall, treatments showed high effect sizes in pre–post comparisons (Hedges' g = 1.34) and medium effect sizes as compared with control conditions (Hedges' g = 0.43). Treatments investigated by at least two studies were cognitive–behavioural therapy (CBT), eye movement desensitization and reprocessing (EMDR), narrative exposure therapy for children (KIDNET) and classroom-based interventions, which showed similar effect sizes. However, studies were very heterogenic with regard to their outcomes. Effects were moderated by type of profession (higher level of training leading to higher effect sizes). A number of effective psychosocial treatments for child and adolescent survivors of disasters exist. CBT, EMDR, KIDNET and classroom-based interventions can be equally recommended. Although disasters require immediate reactions and improvisation, future studies with larger sample sizes and rigorous methodology are needed.
