Abstract
The aim of this study was to investigate if training with the memory technique Method of Loci (MoL) is feasible for children and adolescents with ADHD. Twelve children (aged 9-17 years) with ADHD participated. Training with MoL was done using a mobile application, memorizing a sequence of 20-80 pictures, intended to be carried out five times per week for 4 weeks. Feasibility was assessed with pre- and post-intervention ratings, and with interviews after the training. Qualitative data were analyzed with content analysis. Those who trained with MoL performed better on memory test and reported fewer ADHD symptoms after completing the training, as compared to their baseline levels. All of these children would recommend the training to peers but the duration of training varied considerably. The participants and their parents reported that the MoL training was easy and fun to use, although lack of motivation, distractions in every-day life, and lack of routines created challenges. We conclude that training with MoL was considered feasible by most of the participants. Future research should try to make the intervention more acceptable by motivating the participants and limiting potential distractions and involving larger study groups and controls to study the efficacy of the training.

Moderators of long-term treatment outcome when comparing two group interventions for adolescents with ADHD: who benefits more from DBT-based skills training? BMC Psychiatry 2022; 22:767. [PMID: 36474201 PMCID: PMC9724371 DOI: 10.1186/s12888-022-04435-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 11/28/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Psychosocial interventions for adolescents with attention-deficit/hyperactivity disorder (ADHD), targeting emotional dysregulation and impulsive behaviors, have been requested, but the heterogeneity within this group makes it unlikely that there is one treatment that fits all. The aim of this study was to identify which adolescents with ADHD might have an effect from a structured skills training group (SSTG) based on dialectical behavioral therapy, by exploring pre-treatment characteristics as potential moderators of long-term treatment outcome. METHODS This study was based on follow-up data from a randomized controlled trial comparing the SSTG (n = 71) to a psychoeducational control intervention (n = 57) for adolescents with ADHD (15-18 years old). Clinical characteristics (sex, age, medication status, ADHD presentation, severity of ADHD symptom, psychiatric comorbidity, impairment of emotional dysregulation and functional impairment) were explored as potential moderators of pre-treatment to follow-up change in ADHD symptoms and functional impairment. Moderation analyses were performed using the PROCESS macro for SPSS. RESULTS Three moderators (severity of hyperactivity/impulsivity, conduct problems and impairment of emotional dysregulation) were identified in regard to the outcome self-rated change in ADHD symptoms. Participants with elevated pre-scores on these variables had a better effect of the SSTG than of the psychoeducational control intervention. No moderators were found in regard to the parental-rated outcomes. CONCLUSIONS The SSTG seems to be beneficial for adolescents with ADHD who perceive pronounced symptoms of hyperactivity/impulsivity, conduct problems and emotional dysregulation. Our findings need to be confirmed in future trials evaluating dialectical behavioral therapy-based skills training for adolescents with ADHD, where these moderators could be used as criteria for inclusion or stratification.

Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) in adolescence is associated with functional impairment in several domains of life. To enable development of interventions that more effectively target functional impairment in this age group, the associations between clinical characteristics and impairment need to be clarified. The aim of this study was to investigate the associations between ADHD and functional impairment, if they varied by sex, and the potential impact of comorbid psychiatric symptoms on the associations. METHODS This was a cross-sectional study including adolescents with ADHD (n = 164) and a reference group of adolescents without ADHD (n = 106). Self-ratings and parental ratings of functional impairment in different life domains were used as outcomes in all analyses. Differences between groups were investigated with comparative analyses. General linear models (GLMs) were used to explore associations between ADHD symptoms and functional impairment in adolescents with ADHD, while adjusting for of comorbid symptoms, sex, and medication. RESULTS Adolescents with ADHD displayed higher levels of functional impairment than peers without ADHD, and girls with ADHD rated higher impairment than their male counterparts. The combined ADHD presentation was associated with the highest levels of self-reported impairment, while parental ratings indicated comparable levels of overall impairment across presentations. In the adjusted GLMs, symptoms of inattention were strongly associated with self- and parent-rated impairment in school, but symptoms of hyperactivity/impulsivity were not, whereas symptoms of both inattention and hyperactivity/impulsivity were modestly associated with self-rated impairment with friends. Further, both emotional and conduct problems were associated with impairment in daily life. CONCLUSIONS Our results suggest that attention difficulties, in particular, seem to impair academic functioning in adolescents with ADHD, and interventions targeting such difficulties are warranted. In addition, comorbid symptoms need to be assessed and treated, and self-reports of functioning should be included in research and clinical practice involving adolescents.

Abstract
We examined perceived stress and sleep problems in adolescent ADHD and whether this varies as a function of ADHD presentation and sex. Further, we mapped structural associations between ADHD symptoms, comorbid symptoms, perceived stress, and sleep problems. Participants were 306 adolescents aged 13-19 years (66.8% females, 193 had an ADHD diagnosis, 113 were controls). Parents rated ADHD symptoms, all other constructs were self-rated. Adolescents with ADHD had elevated levels of perceived stress and sleep problems. Girls with ADHD reported the highest levels of perceived stress. Emotional symptoms mediated the effect of inattention whereas conduct problems mediated the effect of hyperactivity/impulsivity on stress and sleep. Perceived stress and sleep problems should be considered when mapping ADHD-related problems. Comorbid symptoms are potential intervention targets that may increase treatment response.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) in adolescence is associated with behavioural, emotional and interpersonal problems, and non-pharmacological treatments targeting these difficulties have been requested. The objective of this study was to evaluate the effectiveness and acceptance of an age-adapted structured skills training group (SSTG) for adolescents with ADHD. Adolescents (n = 184, ages 15-18 years) with a diagnosis of ADHD were randomly assigned to either the SSTG, which is based on dialectical behavioural therapy, or an active control group based on psychoeducation. Symptoms of ADHD, behavioural and emotional problems, functional impairment, and health-related outcomes were assessed with self-ratings and parental ratings two weeks before, two weeks after, and six months after treatment. All participants who completed the pre-treatment measurements (n = 164) were included in the main analyses, which were conducted using a linear mixed model. Our results demonstrated no significant group differences in favour of the SSTG for any of the study outcomes. A majority of the participants in both groups reported that they had increased their knowledge about ADHD, improved their ability to manage problems related to the diagnosis, and would recommend the treatment to others. We conclude that the SSTG seems to be acceptable for adolescents with ADHD in a clinical context. However, the treatment was not proved to be more effective or more acceptable than the psychoeducational control intervention.Trial registration: http://www.isrctn.com/ISRCTN17366720,11/05/2016 , retrospectively registered.

Abstract
Psychoeducation is regarded as a first line of intervention for attention-deficit/hyperactivity disorder (ADHD). Previous studies have been limited to psychoeducation for adult patients or parents of children with ADHD. Therefore, the aim of the present study was to investigate the acceptability and effectiveness of a psychoeducational group intervention for children with ADHD. The two-session psychoeducational intervention, SKILLS, was completed by 125 children (6-12 years) with ADHD and their parents. Self-ratings and parental ratings of ADHD symptoms, functional impairment and attitudes to diagnosis and treatment were collected before and after treatment. Post-treatment client satisfaction and parental responses to an open question about SKILLS were assessed. The data were analyzed using a combination of quantitative and qualitative (content analysis) methods. A majority of the participants expressed satisfaction with the group intervention. The intervention had no effect on symptoms and level of function, although the parents were more positive to their child's diagnosis after the intervention. The parents were positive to the group format and to the opportunity for their children to meet other children with similar symptoms. Parents wished for more interactive elements and more opportunities for children to share experiences. We concluded that the group intervention was accepted by most participants, although more activating exercises and opportunities for interaction between participants should be included. Since the intervention group was not compared with a control group, the results should be interpreted with caution. Future studies should use a randomized control treatment design and investigate the effect on adherence to later treatment.

Abstract
The current study investigates the possibility that athletes have more parallel ADHD symptoms than non-athletes. High-level youth sport athletes were compared with non-athletes in leisure time (i.e., sport) and in the school in ADHD symptoms. Athletes and students were evaluated by a trained psychotherapist using Adult ADHD Self-Report Scale (ASRS) on activities at school and during activities in leisure/sports time. They also filled in the Autism Spectrum Questionnaire (AQ) as a self-report assessment. Results showed significant differences in ASRS-scores for athletes in school and in their sport, with high scores in school and low scores in sport. No differences were found in AQ between the groups. The findings indicate that many athletes might display a cognitive profile of parallel of ADHD criteria. Future research needs to further investigate potential benefits of the cognitive profile in athletes and how they handle different contexts including sport and school settings.

Abstract
BACKGROUND Attention deficit/hyperactivity disorder (ADHD) has a negative impact on several domains of life. However, there is a shortage of evidence-based non-pharmacological treatments for adolescents with ADHD. A structured skills training group (SSTG) based on dialectical behaviour therapy (DBT) has been used in adult patients with ADHD with some promising results, although the treatment has not yet been adapted or evaluated for adolescents with ADHD. This study protocol describes how this treatment was adapted for an adolescent population and how the efficacy of the SSTG will be evaluated using a randomised controlled trial (RCT) design. METHODS A sample of 184 adolescents (15-18 years of age) with a diagnosis of ADHD has been recruited from seven child and adolescent psychiatric outpatient units and randomised to either the SSTG or an active control group based on psychoeducation. Measures are conducted weekly during the treatment, as well as 2 weeks before treatment and 2 weeks and 6 months after treatment. The primary outcome measures are ADHD symptoms, functional impairment, quality of life and mindfulness. Secondary outcome measures are symptoms of comorbid psychopathology, perceived stress and sleep problems. This article describes the design, methods and analysis plan for evaluating the efficacy of the SSTG. DISCUSSION The study will be the first RCT to examine the acceptability and efficacy of a SSTG based on DBT adapted for adolescents with ADHD. We believe that the study will extend the current knowledge base about psychological treatment for adolescents with ADHD. TRIAL REGISTRATION ISRCTN registry ( ISRCTN17366720 ).

Abstract
We previously reported on the cross-national epidemiology of ADHD from the first 10 countries in the WHO World Mental Health (WMH) Surveys. The current report expands those previous findings to the 20 nationally or regionally representative WMH surveys that have now collected data on adult ADHD. The Composite International Diagnostic Interview (CIDI) was administered to 26,744 respondents in these surveys in high-, upper-middle-, and low-/lower-middle-income countries (68.5% mean response rate). Current DSM-IV/CIDI adult ADHD prevalence averaged 2.8% across surveys and was higher in high (3.6%)- and upper-middle (3.0%)- than low-/lower-middle (1.4%)-income countries. Conditional prevalence of current ADHD averaged 57.0% among childhood cases and 41.1% among childhood subthreshold cases. Adult ADHD was significantly related to being male, previously married, and low education. Adult ADHD was highly comorbid with DSM-IV/CIDI anxiety, mood, behavior, and substance disorders and significantly associated with role impairments (days out of role, impaired cognition, and social interactions) when controlling for comorbidities. Treatment seeking was low in all countries and targeted largely to comorbid conditions rather than to ADHD. These results show that adult ADHD is prevalent, seriously impairing, and highly comorbid but vastly under-recognized and undertreated across countries and cultures.
