Goal management training for improving fatigue in children and adolescents with acquired brain injuries: A 2-year follow-up of a randomised controlled trial.

To explore the long-term effectiveness of a paediatric adaptation of Goal Management Training (pGMT), relative to a psychoeducative program (pBHW), in reducing fatigue after pABI 2 years post-intervention. Thirty-eight youths and their parents completed the Paediatric Quality of Life - Multidimensional Fatigue Scale. Primary outcome measures were Total Fatigue Score, General fatigue, Cognitive fatigue, and Sleep/rest fatigue (parent-report). No significant differences in fatigue symptoms by the parental report was observed between the intervention groups at the 2-year follow-up (total score: F = .16, p = .69; general fatigue: F = .36, p = .55; sleep/rest: F = .48, p = .49; and cognitive fatigue: F = .09, p = .76), nor any time*group interactions (total score: F = .25, p = .86; general fatigue: F = .39, p = .76; sleep/rest: F = .20, p = .89; and cognitive fatigue: F = .08, p = .97). In total, 45% of the participants in the pGMT group and 25% in the pBHW group demonstrated a reliable positive clinical change. The significant improvements in fatigue symptoms that were demonstrated 6 months post-intervention could not be confirmed in this 2-year follow-up study. However, a continued positive tendency on most dimensions of fatigue for the participants in the pGMT group could be observed, suggesting that cognitive rehabilitation may help reduce fatigue.

Objective and subjective cognitive status after intensive care unit treatment for COVID-19.

Purpose: Intensive care unit (ICU) survivors can experience wide-ranging and long-lasting symptoms after hospital discharge. Cognitive impairment has received increased attention in relation to the COVID-19 pandemic and can affect patients' long-term quality of life. This study aimed to investigate the prevalence of cognitive impairment using an objective neurocognitive test 6 and 12 months following ICU admission and possible predictive factors for scoring below the defined cut-off. We also explored the prevalence of subjective cognitive complaints at 12 months, including the associated factors. Methods: This was a prospective observational study of a national cohort of COVID-19 ICU survivors during the three first pandemic waves in Norway. Data was collected by the Norwegian Intensive Care and Pandemic Registry and the study group. Results: At the six-month follow-up, 23.1% (95% CI [18.2─28.5]) of the 273 respondents scored below the cut-off on the Mini-MoCA, indicating mild cognitive impairment. At the 12-month follow-up, the prevalence declined to 11.1% (95% CI [7.5─15.6]) in 253 respondents. Older age (OR 1.06, 95% CI [1.02─1.12]) and depression (OR 1.25, 95% CI [1.07─1.55]) were associated with cognitive impairment at six months. At 12 months, almost half of the patients reported subjective cognitive complaints. Symptoms of mental health problems and fatigue were associated with subjective cognitive complaints in our exploratory analyses. Conclusion: Cognitive impairment declined significantly from 6 to 12 months in this cohort of COVID-19 ICU patients, while subjective cognitive complaints remained high at 12 months, perhaps attributed to a high total symptom burden.

Inter-rater agreement between patient- and proxy-reported cognitive functioning in intensive care unit patients: A cohort study.

BACKGROUND: Health status, including cognitive functioning before critical illness, is associated with long-term outcomes in intensive care unit survivors. Premorbid data are therefore of importance in longitudinal studies. Few patients can self-report at intensive care admission. Consequently, proxy assessments of patients' health status are used. However, it remains unclear how accurately proxies can report on an intensive care patient's cognitive status. OBJECTIVES: The aim of this study was to examine the agreement between patient- and proxy-reporting of the Cognitive Failures Questionnaire and to compare the agreement between proxy reports using the latter questionnaire and the Informant Questionnaire of Cognitive Decline in the Elderly as a reference. METHODS: The present cohort study is part of a longitudinal multicentre study collecting both patient and proxy data using questionnaires and clinical data from medical records during intensive care unit stays. Agreement on patient and proxy pairs was examined using intraclass correlation coefficient (ICC), Spearman's correlation, percentage agreement, and Gwet's AC1 statistics. Agreement between the proxy-reported questionnaires was examined using percentage agreement and Gwet's AC1 statistics. RESULTS: In total, we collected 99 pairs of patient-proxy assessments and 158 proxy-proxy assessments. The ICC for the sum scores revealed moderate agreement (n = 99; ICC = 0.59; 99% confidence interval [CI]: [0.30-0.76]) between patient and proxy. Agreement on items was poor (AC1 = 0.13; 99% CI: [0.01-0.24]) to moderate (AC1 = 0.55; 99% CI: [0.43-0.68]). Agreement using cut-off scores (>43) to indicate cognitive impairment was very good (89.9%, AC1 = 0.87; 99% CI: [0.79-0.95]). Agreement between the proxy-reported Cognitive Failures Questionnaire (>43) and the reference questionnaire (≥3.5) was also very good (n = 158; 85%, AC1 = 0.82; 99% CI: [0.74-0.90]). CONCLUSIONS: Proxy assessments of the Cognitive Failures Questionnaire (>43) may be used to indicate cognitive impairment if patients are unable to self-report. Agreement was high between the two questionnaires determined by proxies, showing that these can be used interchangeably to assess cognitive functioning if proxy reporting is needed.

Neurocognitive outcome and associated factors in long-term, adult survivors of childhood acute lymphoblastic leukemia, treated without cranial radiation therapy.

OBJECTIVE: There is limited research on neurocognitive outcome and associated risk factors in long-term, adult survivors of childhood acute lymphoblastic leukemia (ALL), without treatment of cranial radiation therapy. Moreover, the impact of fatigue severity and pain interference on neurocognition has received little attention. In this cross-sectional study, we examined neurocognitive outcome and associated factors in this population. METHOD: Intellectual abilities, verbal learning/memory, processing speed, attention, and executive functions were compared to normative means/medians with one sample t tests or Wilcoxon signed-rank tests. Associations with risk factors, fatigue severity, and pain interference were analyzed with linear regressions. RESULTS: Long-term, adult survivors of childhood ALL (N = 53, 51% females, mean age = 24.4 years, SD = 4.4, mean = 14.7 years post-diagnosis, SD = 3.4) demonstrated above average intellectual abilities, but performed below average in attention, inhibition, processing speed, and shifting (p < 0.001). Executive functioning complaints were significantly higher than normative means, and positively associated with fatigue (p < 0.001). There was no interaction between sex and fatigue and no neurocognitive impairments were associated with pain interference, risk group, age at diagnosis, or sex. CONCLUSIONS: Long-term, adult survivors of ALL treated without cranial radiation therapy, demonstrate domain-specific performance-based neurocognitive impairments. However, continued research on the neurocognitive outcome in this population as they age will be important in the coming years. Executive functioning complaints were frequently in the clinical range, and often accompanied by fatigue. This suggests a need for cognitive rehabilitation programs.

Effects of Goal Management Training on self-efficacy, self-esteem, and quality of life for persons with schizophrenia spectrum disorders.

Persons with schizophrenia often show executive dysfunction assessed with both subjective (self-report) and objective (neuropsychological tests) measures. In a recent randomized controlled trial (RCT), subjective executive functioning in everyday life was improved following Goal Management Training (GMT). The aim of the current study is to investigate the potential of GMT to improve secondary well-being outcomes from that RCT, including self-esteem, self-efficacy, and quality of life in persons with schizophrenia spectrum disorders. Since well-being is frequently lower in persons with schizophrenia compared to healthy individuals, further knowledge about well-being as an outcome after cognitive remediation may have implications for clinical treatment. Sixty-five participants were randomly assigned to GMT (n = 31) or a waiting list control condition (n = 34). Assessments were conducted at baseline (T1), immediately after the intervention (T2-5 weeks), and at six-month follow-up (T3). Measures included the Rosenberg Self-Esteem Scale, the Perceived Quality of Life Scale, and the General Self-Efficacy Scale. Results were analyzed using a linear mixed model analysis for repeated measures. There were no significant effects of GMT on self-esteem or quality of life. Only the GMT group showed a significant increase in self-efficacy that was most evident at six months follow-up, F(1, 34) = 10.71, p = 0.002, d = 0.71. Improved self-efficacy was found to correlate significantly with a reduction in perceived executive dysfunction in an exploratory post hoc analysis. Our findings demonstrate the potential of GMT in improving self-efficacy in schizophrenia Clinical trial registration:https://clinicaltrials.gov, NCT03048695.

Exercise therapy, education, and cognitive behavioral therapy alone, or in combination with total knee arthroplasty, in patients with knee osteoarthritis: a randomized feasibility study.

BACKGROUND: One in five patients experience chronic pain 1 year after total knee arthroplasty (TKA), highlighting the need for enhanced treatment strategies to improve outcomes. This feasibility trial aimed to optimize the content and delivery of a complex intervention tailored to osteoarthritis (OA) patients at risk of poor outcome after TKA and assess the feasibility of initiating a full-scale multicenter randomized controlled trial (RCT). METHODS: Patients scheduled for TKA were included between August 2019 and June 2020 and block-randomized into one of three groups: (a) 12-week exercise therapy and education (ExE) and 10-module internet-delivered cognitive behavioral therapy (iCBT), (b) TKA followed by ExE and iCBT and (c) TKA and standard postoperative care. Outcomes were (i) recruitment and retention rate, (ii) compliance to the intervention and follow-up, (iii) crossover, and (iv) adverse events, reported by descriptive statistics. RESULTS: Fifteen patients were included in the study. Only 1 out of 146 patients screened for eligibility was included during the first 4 months. During the next 3 months, 117 patients were not included since they lived too far from the hospital. To increase the recruitment rate, we made three amendments to the inclusion criteria; (1) at-risk screening of poor TKA outcome was removed as an eligibility criterion, (2) patients across the country could be included in the study and (3) physiotherapists without specific certification were included, receiving thorough information and support. No patients withdrew from the study or crossed over to surgery during the first year. Nine out of 10 patients completed the ExE program and six out of 10 completed the iCBT program. Fourteen out of 15 patients completed the 1-year follow-up. One minor adverse event was registered. CONCLUSIONS: Except for recruitment and compliance to iCBT, feasibility was demonstrated. The initial recruitment process was challenging, and necessary changes were made to increase the recruitment rate. The findings informed how a definitive RCT should be undertaken to test the effectiveness of the complex intervention. TRIAL REGISTRATION: The MultiKnee RCT, including the feasibility study, is pre-registered at ClinicalTrials.gov: NCT03771430 11/12/2018.

Family members' and friends' reports after standard and intensive group treatment for social communication difficulties following acquired brain injury - a mixed method approach.

OBJECTIVE: To examine family members/friends' perception of change following standard and intensive group interactive structured treatment (GIST) for persons with social communication difficulties (SCDs). METHODS: A parallel mixed methods design combining data from questionnaires, the Goal Attainment Scale, and interviews. PARTICIPANTS: Forty-nine adult (>18 years) family members/friends (69.4% female) of persons with SCDs and acquired brain injury (ABI) (cohabitating partner, 53.1%; other relatives, 30.6%; friends, 16.3%). INTERVENTION: Standard GIST consisted of 12 weekly outpatient sessions (2.5 h). Intensive GIST consisted of 4 weeks of inpatient rehabilitation (2 × 3 days/week, 2 × 4 days/week). Both treatments included 3- and 6-month follow-ups. MAIN OUTCOME MEASURES: Quantitative measures (n = 49) included the following informant reports: Latrobe Communication Questionnaire (LCQ), Social Communication Skills Questionnaire-Adapted (SCSQ-A), Behavior Rating Inventory for Executive Functions-Adult version (BRIEF-A), and Goal Attainment Scale. The qualitative measure (n=9) was an interview performed at 6-month follow-up. RESULTS: Converging results were found, suggesting a perceived positive change over time for both standard and intensive GIST, with no substantial differences reported between the treatments. CONCLUSIONS: Family members/friends reported improved social communication skills of the persons with SCDs following standard and intensive GIST. However, the integration of data showed the complexity of assessing SCDs and the need for further investigation.

Cognitive and behavioural rehabilitation interventions for survivors of childhood cancer with neurocognitive sequelae: A systematic review.

There is considerable interest in cognitive and behavioural interventions to manage and improve neurocognitive (dys)functions in childhood cancer survivors and the literature is rapidly growing. This systematic review aimed to examine the literature of such interventions and their impact on executive functions (EFs) and attention. A search of relevant manuscripts was performed in PubMed, PsycINFO, and Web of Science in March 2023 in accordance with the PRISMA statement. After screening 3737 records, 17 unique studies published between 2002 and 2022 were charted and summarized. Participants (N = 718) were mostly children (M = 12.2 years), who were long-term survivors (M = 5.0 years post treatment) of brain or CNS tumours (48%). Identified interventions included computerized cognitive training, physical activity, and cognitive interventions with compensatory strategy training. The highest quality RCT studies included computerized training (i.e., Cogmed), neurofeedback, and exergaming. Evidence suggests that Cogmed may improve the performance of certain working memory tasks (near transfer) and possibly improve visual attention tasks for individuals with working memory impairments. However, the evidence did not support far transfer of effects to real life. No significant effects (near or far-transfer) were found following neurofeedback and exergaming interventions. Finally, a knowledge gap was identified for interventions directed at long-term survivors in adulthood.

Post-traumatic stress symptoms six months after ICU admission with COVID-19: Prospective observational study.

AIMS AND OBJECTIVES: The aim of this study was to investigate the prevalence of post-traumatic stress symptoms, and to identify possible predictive factors in Norwegian intensive care unit survivors, 6 months after admission to the intensive care unit with COVID-19. BACKGROUND: The SARS CoV-2 virus causing COVID-19 has spread worldwide since it was declared a pandemic in March 2020. The most severely ill patients have been treated in the intensive care due to acute respiratory failure and also acute respiratory distress syndrome. It is well documented that these severe conditions can lead to complex and long-lasting symptoms, such as psychological distress, and was, therefore, investigated for the specific COVID-19 population. DESIGN: Prospective observational study. METHODS: Clinical data and patient reported outcome measures were collected by the Norwegian Intensive Care and Pandemic Registry and by the study group 6 months after admission to an intensive care unit. RESULTS: Among 222 COVID-19 patients admitted to Norwegian intensive care units between 10 March and 6 July 2020, 175 survived. The study sample consisted of 131 patients who responded to at least one patient reported outcome measure at 6 months following admission. The primary outcome was self-reported post-traumatic stress symptoms, using the Impact of Event Scale-6 (n = 89). Of those, 22.5% reported post-traumatic stress symptoms 6 months after admission. Female gender, younger age and having a high respiratory rate at admission were statistically significant predictive factors for reporting post-traumatic stress symptoms. CONCLUSIONS: The result is in accordance with previously published research with comparable populations, suggesting that for many COVID-19 survivors psychological distress is a part of the post-acute sequelae. Results from the present study should be replicated in larger datasets. RELEVANCE TO CLINICAL PRACTICE: This project provides important insight to post-acute sequelae after COVID-19 that patients may experience after critical illness.

Executive function in children with disruptive mood dysregulation disorder compared to attention-deficit/hyperactivity disorder and oppositional defiant disorder, and in children with different irritability levels.

Addressing current challenges in research on disruptive mood dysregulation disorder (DMDD), this study aims to compare executive function in children with DMDD, children with attention-deficit/hyperactivity disorder (ADHD), and children with oppositional defiant disorder (ODD). We also explore associations between irritability, a key DMDD characteristic, and executive function in a clinical sample regardless of diagnosis. Our sample include children (6-12 years) referred to child psychiatric clinics. Measures of daily-life (parent-reported questionnaire) and performance-based (neuropsychological tasks) executive function were applied. Identifying diagnoses, clinicians administered a standardized semi-structured diagnostic interview with parents. Irritability was assessed by parent-report. First, we compared executive function in DMDD (without ADHD/ODD), ADHD (without DMDD/ODD), ODD (without DMDD/ADHD) and DMDD + ADHD (without ODD). Second, we analyzed associations between executive function and irritability using the total sample. In daily life, children with DMDD showed clinically elevated and significantly worse emotion control scores compared to children with ADHD, and clinically elevated scores on cognitive flexibility compared to norm scores. Children with DMDD had significantly less working memory problems than those with ADHD. No differences were found between DMDD and ODD. Increased irritability was positively associated with emotional dyscontrol and cognitive inflexibility. For performance-based executive function, no diagnostic differences or associations with irritability were observed. We discuss how, in daily life, children with high irritability-levels get overwhelmed by feelings without accompanying regulatory capacities.

Neuropsychological mechanisms of social difficulties in disruptive mood dysregulation disorder versus oppositional defiant disorder.

Children with Disruptive Mood Dysregulation Disorder (DMDD) or Oppositional Defiant Disorder (ODD) are characterized by irritability and social difficulties. However, the mechanisms underlying these disorders could be different. This study explores differences in social cognition and executive function (EF) across DMDD and ODD and the influence of these factors and their interaction on social problems in both groups. Children with DMDD (n = 53, Mage = 9.3) or ODD (n = 39, Mage = 9.6) completed neuropsychological tasks measuring social cognition (Theory of Mind and Face-Emotion Recognition) and EF (cognitive flexibility, inhibition, and working memory). Parents reported social problems. More than one-third of the children with DMDD and almost two-thirds of those with ODD showed clear difficulties with Theory of Mind. Most children with DMDD (51-64%) or ODD (67-83%) showed difficulties with EF. In children with DMDD, worse EF (ß = -.36) was associated with more social problems, whereas in children with ODD, better EF (ß = .44) was associated with more social problems. In those with ODD, but not in those with DMDD, the interaction between social cognition and EF contributed to the explained variance of social problems (ß = -1.97). Based on the observed interaction pattern, enhanced EF may lead to increased social problems among children with ODD who also exhibit social cognition difficulties. This study suggests the existence of distinct neuropsychological mechanisms underlying the social issues observed in children with DMDD versus those with ODD.

Executive control training for adolescents with ADHD: Study protocol for a randomised controlled trial.

BACKGROUND: Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent neurodevelopmental conditions diagnosed during childhood and adolescence. In addition to the commonly observed symptoms of inattention, hyperactivity, and impulsivity, individuals with ADHD often experience impairments in executive functions (EFs). Goal management training (GMT) is a cognitive remediation intervention targeting EFs, with empirical support from studies with adult populations, including ADHD. The objective of the upcoming trial is to assess the effectiveness of GMT for adolescents with ADHD. METHODS: This pre-registered protocol outlines a multi-centre randomised controlled trial (RCT) comparing GMT to treatment as usual (TAU) to improve EFs. We aim to recruit 120 participants, aged 12 to 18 years, recently diagnosed with ADHD. Participants will be randomly allocated to the group-based GMT intervention in addition to TAU, or the TAU condition, through block randomisation with site stratification. GMT will be delivered in groups of four to six participants, with weekly two-hour sessions for seven weeks, complemented by separate parent and teacher sessions. TAU is standard community mental health treatment. The primary outcome measure will be parent-reported EF assessed with the Behaviour Rating Inventory of Executive Function 2 (BRIEF-2). Secondary outcomes will include ADHD symptom measures, social functioning, quality of life, and neuropsychological tests (attention span, inhibition, working memory, and visuo-motor speed). The outcome assessments will be conducted at baseline, 12 weeks, 12 months, and 24 months post-treatment. CONCLUSION: The study findings will contribute to determine the effectiveness of a non-pharmacological ADHD treatment, including outcome trajectories up to 24 months post-treatment.

Disruptive Mood Dysregulation Disorder in a Norwegian Clinical Child Population.

BACKGROUND: Disruptive Mood Dysregulation Disorder was included in DSM-5 to accommodate new research addressing aspects of emotional dysregulation in children suffering from disruptive behavior problems. Despite growing interest in Disruptive Mood Dysregulation Disorder, few studies have looked at prevalence rates in European clinical populations. The primary objective of this study was to examine the prevalence and characteristics associated with Disruptive Mood Dysregulation Disorder in a Norwegian clinical sample. METHODS: The present study assessed children 6-12 years of age referred to a mental health clinic for evaluation and treatment (N = 218, Mage = 9.6, 60.4% boys) and compared those who did and did not meet Disruptive Mood Dysregulation Disorder diagnostic criteria. Diagnoses were determined using K-SADS-PL 2013. Associated difficulties at home and in school were measured by Achenbach Systems of Empirically Based Assessment battery. RESULTS: In this clinical sample, 24% met the diagnostic criteria for Disruptive Mood Dysregulation Disorder. Children with Disruptive Mood Dysregulation Disorder were more likely than those without Disruptive Mood Dysregulation Disorder to be male (77% vs. 55%, p = .008), be living in poverty, have multiple mental health diagnoses (79% vs. 53%, p = .001), and have lower global functioning levels as measured by Children's Global Assessment Scale (range 0-100, M = 47, SD = 8.5 vs. M = 57, SD = 11.4, p=<.001). Finally, parents and teachers of children with Disruptive Mood Dysregulation Disorder reported lower overall competence and adaptive functioning, and higher total symptom load than children with other diagnoses. CONCLUSION: Disruptive Mood Dysregulation Disorder is highly prevalent in a Norwegian clinical sample and displays a high symptom load. Our results are in accordance with similar studies. Consistent findings across the world may support Disruptive Mood Dysregulation Disorder as a valid diagnostic category.

Improvement of anxiety in ADHD following goal-focused cognitive remediation: a randomized controlled trial.

Introduction: Despite the high prevalence and detrimental consequences of cognitive and executive dysfunction in ADHD, the evidence base of cognitive remediation in the adult ADHD population is sparse. Executive problems can increase both anxiety and depression in ADHD. Thcus, it is important to develop treatment options for adults with ADHD, aiming to improve goal-directed behavior and mood. Goal Management Training (GMT) is an intervention that has received empirical support in improving executive functions and mood in normal aging and for various neurological and psychiatric conditions. The present randomized controlled trial investigated the effects of a goal-focused intervention combining 1) group-based GMT incorporating psychoeducation about ADHD and 2) guidance in implementing individual goals for coping with executive problems in everyday life, compared to treatment as usual (TAU). The primary outcome was perceived executive functioning in everyday life. Secondary outcomes included psychological well-being (anxiety, depression, and coping with ADHD symptoms). Methods: We recruited 81 adult participants with a verified ADHD diagnosis (Mage = 31 years). Inclusion was based upon the presence of executive functioning complaints. The participants were randomly assigned to either the intervention or TAU. The intervention group (n = 41) received 16 hours of GMT and psychoeducation, in addition to 4 individual sessions focusing on formulating goals. The goals were assessed in 6 bi-weekly phone calls in the first three months following the group sessions. Participants in the TAU group (n = 40) received standard, individually-adapted follow-up in an outpatient psychiatric health care setting. All participants were assessed at baseline, post-intervention, and at 8-month follow-up (main measurement time point). Results: Significant improvements in everyday executive functioning, psychological wellbeing, and symptoms of ADHD from baseline to 8-month follow-up were reported in both groups. The intervention group reported a significantly higher reduction in symptoms of anxiety compared to TAU. Conclusions. Our findings provide support for considering cognitive remediation as a treatment option for patients with ADHD.Clinical Trial Registration: https://clinicaltrials.gov/study/NCT04638283?term=NCT04638283&rank=1, identifier: NCT04638283.

Excessive hair cortisol concentration as an indicator of psychological disorders in children.

Cortisol in hair is a new biomarker assessing long-term hypothalamic-pituitary-adrenal (HPA) axis activity, which is related to emotion regulation. We compare hair cortisol concentrations (HCC), in clinically referred children with disruptive mood dysregulation disorder (DMDD) (n = 19), children with other types of psychological disorders (n = 48), and healthy subjects (n = 36). We also investigate the association between HCC and irritability, age, and sex. Our results show that children with DMDD or other types of psychological disorders have higher HCC than healthy subjects, p < .001, ηp2 = .39. No difference between children with DMDD and those with other types of psychological disorders was found, p = .91, nor an association between HCC and irritability in the clinical sample, p = .32. We found a significant negative correlation between HCC and age in those with DMDD, r = -0.54, p < .05, but not in the normative sample, r = -0.20, p = .25. No differences in HCC between girls and boys were found in the normative sample, p = .49. Children in need of psychological treatment, including those with DMDD, seem to have dysregulated HPA-axis activity over time. Excessive accumulated cortisol concentrations in hair could be an indicator of a psychological disorder in children.

Cognitive rehabilitation in paediatric acquired brain injury-A 2-year follow-up of a randomised controlled trial.

Background: Goal management training (GMT), a metacognitive rehabilitation method that has been demonstrated to improve executive function (EF) in adults with acquired brain injury (ABI), could potentially be effective for children in the chronic phase of ABI. In a previously published randomised controlled trial (RCT), the efficacy of a paediatric adaptation of GMT (pGMT) compared to a psychoeducative control intervention (paediatric Brain Health Workshop, pBHW) was investigated. Comparable improvements in EF in both groups were found at 6-month follow-up. However, a specific effect of pGMT could not be conclusively proven. The present study reports 2-year follow-up data (T4; T1: baseline, T2: post-intervention, T3: 6-month follow-up, and T4: 2-year follow-up) from this original RCT. Methods: A total of 38 children and adolescents and also their parents completed questionnaires tapping into daily life EF. Explorative analyses were conducted comparing the 2-year follow-up data (T4) with the baseline (T1) and 6-month follow-up data (T3) for T4-participants in the two intervention groups (pGMT; n = 21, pBHW; n = 17), and we also assessed T4-participants vs. non-responders (n = 38) in the RCT. Primary outcome measures were the Behavioural Regulation Index (BRI) and the Metacognition Index (MI) derived from the Behaviour Rating Inventory of Executive Function (BRIEF) parent report. Results: No difference between intervention groups was found (BRI, F = 2.25, p = 0.143, MI, F = 1.6, p = 0.213), and no time*group interaction (BRI, F = 0.07, p = 0.976, MI, F = 0.137, p = 0.937) could be seen at the 2-year follow-up. Nevertheless, both pGMT and the pBHW groups improved daily EF as measured by parental reports over time from the baseline to T4 (p = 0.034). T4 participants and non-responders shared similar baseline characteristics. Conclusion: Our results extend the findings from the 6-month follow-up previously published. Both pGMT and pBHW groups sustained their improvements in daily life EFs from the baseline, but additional effectiveness of pGMT relative to pBHW was not found.

Rehabilitation of Social Communication Skills in Patients With Acquired Brain Injury With Intensive and Standard Group Interactive Structured Treatment: A Randomized Controlled Trial.

OBJECTIVE: To determine the efficacy of group interactive structured treatment (standard GIST) for improving social communication difficulties in a wider acquired brain injury (ABI) population compared to a waitlist control (WL). Secondary objectives were to (a) explore GIST across delivery formats by comparing the results to an intensive inpatient version of GIST (intensive GIST) and (b) compare the within-subject results for WL and intensive GIST. DESIGN: Randomized controlled trial with WL and repeated measures (pre- and posttraining, 3- and 6-month follow-ups). SETTING: Community and rehabilitation hospital. PARTICIPANTS: Forty-nine persons (27-74 years) with ABI and social communication difficulties (26.5% traumatic brain injury, 44.9% stroke, 28.6% other), minimum 12 months postinjury. INTERVENTION: Standard GIST (n=24) consisted of 12 weekly outpatient interactive group sessions (2.5 hours/session) and follow-up. Intensive GIST (n=18) consisted of 4 weeks with daily 4-hour inpatient group sessions (2 × 3 d/wk, 2 × 4 d/wk) and follow-up. MAIN OUTCOME MEASURES: La Trobe Questionnaire, a self-report questionnaire measuring social communication. Secondary measures: Social Communication Skills Questionnaire-Adapted, Goal Attainment Scale, Mind in the Eyes test, and questionnaires addressing mental and cognitive health, self-efficacy, and quality of life. RESULTS: When comparing the standard GIST and WL results, a trend of improvement was found for the main outcome, La Trobe Questionnaire, and a statistically significant improvement was found for the secondary outcome Social Communication Skills Questionnaire-Adapted. Comparing standard GIST and intensive GIST, improvement in social communication skills after both treatments was detected and maintained at 6-month follow-up. No statistically significant difference was found between groups. Goal attainment was achieved and maintained during follow-up for both standard and intensive GIST. CONCLUSIONS: Social communication skills were improved after both standard and intensive GIST, indicating that GIST can be delivered across treatment formats and to a wider ABI population.

Characteristics associated with the discrepancy between subjective and objective executive functioning in depression.

Major depressive disorder (MDD) is associated with both self-reported (subjective) cognitive complaints and deficits in neurocognitive (objective) measures, but the correspondence between subjective and objective measures of cognition is low. This cross-sectional study aimed to (1) assess the association between subjective and objective measures of executive functions (EFs), and (2) explore factors associated with the discrepancy between subjective and objective EFs in MDD. Sixty-two participants with current or previous mild to moderate MDD and subjective EF complaints completed a clinical trial baseline assessment. An objective EF composite score was drawn from six neurocognitive measures, while the Behavior Rating Inventory of Executive Function-Adult version was applied as a measure of subjective EF. The association between the subjective and objective composites was evaluated using Spearman's rank order correlation. A discrepancy score was calculated to quantify the difference between subjective and objective EF. Factors associated with the discrepancy score were analyzed using regression analysis (p < .05). Participants reported extensive EF difficulties, but most performed in the normal range on objective EF measures. A weak correlation was detected between the subjective and objective measures (rs = .015). More rumination (ß = -.364) and higher IQ (ß = -.420) were associated with reporting more subjective complaints than was evident from objective measures of EF (i.e., underestimation). Subjective and objective EF measures are weakly overlapping in MDD. Findings underscore recommendations to include both subjective and objective measures when assessing EFs in depression. In addition, findings suggest that targeting ruminative processes could help correct underestimation.

Validity of the Behavioural Assessment of the Dysexecutive Syndrome for Children (BADS-C) in children and adolescents with pediatric acquired brain injury.

The Behavioural Assessment of the Dysexecutive Syndrome for Children (BADS-C) was developed to address the need for a standardized ecologically valid test of executive function (EF) in the pediatric population. Our study aimed to investigate the discriminant, concurrent, and ecological validity of BADS-C in a sample with pediatric acquired brain injury (pABI). Seventy-four participants with pABI aged 10-17 years were included to a pre-registered randomized controlled trial, and baseline assessment was used for the current study. Controls consisted of 60 participants aged 10-17 years. Participants with pABI were assessed with neuropsychological tests and questionnaires of EF, and measurements of general intellectual ability (IQ). Results showed that all BADS-C subtests discriminated between participants with pABI and controls, except for the Playing Cards Test. Concurrent and ecological validity was demonstrated through associations between BADS-C total score, Key Search Test, and Zoo Map Test 1, and neuropsychological tests and teacher questionnaire ratings of EF. Key Search Test and Zoo Map Test 1 predicted teacher ratings of EF, beyond IQ and other neuropsychological test of EF. These findings provide support for BADS-C as a valid clinical assessment tool that can detect everyday executive dysfunction in the pABI population, and guide rehabilitation and treatment decisions.

Moderators of metacognitive strategy training for executive functioning in early schizophrenia and psychosis risk.

Goal Management Training (GMT) improved self-reported executive functioning in a recent randomized, controlled trial in early intervention for psychosis participants. Little is known about the mechanism for this benefit, so this study investigates objectively measured executive function, the difference between subjective and objective executive function, independent living and employment status as potential moderators of efficacy of GMT. Baseline scores from 81 participants (GMT n = 39 vs Treatment-as-usual; TAU n = 42) were analyzed in a linear mixed model analysis for repeated measures as predictors of improvement on the self-reported Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A) immediately and 30 weeks after GMT. Potential moderators were scores from objective measures of executive functioning, discrepancy between subjective and objective measures, independent living and employment status. Discrepancy was assessed by comparing four clusters of participants with differing patterns of scores. The effect of GMT remained significant regardless of initial objective executive functioning at baseline. Those with higher subjective complaints at baseline in two clusters with (i) both objective and subjective executive dysfunction, and (ii) mostly subjective executive dysfunction experienced greater change after treatment. Living arrangements or participation in education or work did not significantly moderate the effects of GMT. Poor performance on neuropsychological tasks is not an obstacle to making use of GMT, but further knowledge is needed about the benefits of strategy training for individuals with a combination of poor performance with few subjective complaints.
