Executive functions in adolescents with spina bifida: relations with autonomy development and parental intrusiveness

Growth of condition-related knowledge among youth with spina bifida: associations with neurocognitive functioning and self-management skills

OBJECTIVE

This study aims to characterize the growth in condition-related knowledge in youth with spina bifida (SB), identify neurocognitive predictors of growth, and examine associations between growth in knowledge and subsequent levels of medical self-management skills.

METHODS

Participants were recruited from a larger longitudinal study involving 140 youth with SB and caregivers, who completed questionnaires and interviews every 2 years over 8 years. The current study included the youth report of condition-related knowledge and medical self-management skills. Youth attention and executive functioning were assessed via parent and teacher reports and performance-based assessment. Latent growth curves were conducted in Mplus Version 8 (Múthen, L. K., & Múthen, B. O. [1998]. Mplus User's Guide. [Eighth]. Muthén & Muthén) to examine change over time in youth-reported condition-related knowledge. Neurocognitive variables were included as predictors of growth in knowledge and regression analyses were used to predict medical self-management skills from growth in condition-related knowledge.

RESULTS

Youth condition-related knowledge increased linearly. Better youth performance on working memory and attention performance-based tasks predicted a higher intercept for condition-related knowledge at T1, but not slope. Teacher and parent reports of inattention and executive dysfunction were not consistent predictors of intercept and growth. Slope of condition-related knowledge was not predictive of subsequent youth self-management skills.

CONCLUSIONS

Youth with SB gain condition-related knowledge over time. However, executive dysfunction and inattention may impede gains in condition-related knowledge. Thus, executive functioning supports, attention-related interventions, and psychoeducation may support condition-related knowledge gains and later medical self-management skills, but further research assessing family and cultural factors is needed.

The Cognitive Orientation to daily Occupational Performance (CO-OP) Approach is superior to ordinary treatment for achievement of goals and transfer effects in children with cerebral palsy and spina bifida - a randomized controlled trial

PURPOSE

Children with cerebral palsy (CP) or spina bifida (SB) often have executive dysfunction affecting activity performance. With the Cognitive Orientation to daily Occupational Performance (CO-OP) Approach, children find their own way to perform activities, using problem-solving strategies and meta-cognitive thinking. The present study aimed to investigate the effectiveness of the CO-OP Approach in children with CP or SB, compared with conventional rehabilitation, in achieving self-identified activity goals, and to explore any generalization and transfer effects.

METHOD

Randomized controlled trial, CO-OP versus treatment as usual, 38 children (7-16 years) participated. Each child identified four goals (to study generalization and transfer, one remained untrained). Primary outcomes: Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS). Secondary outcomes assessed executive functions and self-rated everyday-life competence.

RESULTS

Self-rated goal attainment (COPM) was significantly greater for both trained and untrained goals in the CO-OP group compared with the control group. The rating of observed performance (PQRS) was significantly higher for trained goals in the CO-OP group. The CO-OP group experienced fewer problems in everyday life after treatment. Executive functions did not differ significantly between groups.

CONCLUSION

CO-OP is more effective than ordinary treatment in achieving both trained and untrained goals.IMPLICATIONS FOR REHABILITATIONCO-OP enables children with CP (MACS levels I-III) or SB without intellectual disabilities to reach self-identified goals.CO-OP shows transfer effects to new activities and situations, which may enhance children's self-efficacy.CO-OP is an important complement to conventional rehabilitation services for children with CP and SB.

Hydrocephalus: A neuropsychological and theoretical primer

Hydrocephalus is a common neurological condition, the hallmark feature of which is an excess in production, or accumulation, of cerebrospinal fluid in the ventricles. Although it is associated with diffuse damage to paraventricular brain areas, patients are broadly typified by a particular pattern of cognitive impairments that include deficits in working memory, attention, and spatial abilities. There have, however, been relatively few neuropsychological accounts of the condition. Moreover, theories of the relationship between aetiology and impairment appear to have emerged in isolation of each other, and proffer fundamentally different accounts. In this primer, we aim to provide a comprehensive and contemporary overview of hydrocephalus for the neuropsychologist, covering cognitive sequelae and theoretical interpretations of their origins. We review clinical and neuropsychological assays of cognitive profiles, along with the few studies that have addressed more integrative behaviours. In particular, we explore the distinction between congenital or early-onset hydrocephalus with a normal-pressure variant that can be acquired later in life. The relationship between these two populations is a singularly interesting one in neuropsychology since it can allow for the examination of typical and atypical developmental trajectories, and their interaction with chronic and acute impairment, within the same broad neurological condition. We reflect on the ramifications of this for our subject and suggest avenues for future research.

Neurodevelopmental Implications on Urological Self-management Among People Living With Spina Bifida: A Practical Guide for Urology Providers

Although folic acid fortification and advances in prenatal repair have reduced Spina Bifida (SB) prevalence and the severity of comorbidities, individuals with SB remain at elevated risk for neurocognitive impairments that studies have shown can negatively impact, among other things, urological self-care. Identifying and addressing these impairments with practical interventions can meaningfully improve long-term outcomes for individuals with SB. We review neurocognitive impairments associated with SB and provide practical solutions to support improvement of long-term urological outcomes.

Exploratory study of the provision of academic and health-related accommodations to transition-age adolescents and emerging adults with spina bifida

PURPOSE

The purpose of this exploratory study was to investigate the types of academic and health-related accommodations provided to adolescents and emerging adults with spina bifida aged 9-20 years.

METHODS

Data were extracted from the paper and electronic records of transition-age youth enrolled in the study. Four open ended items involved content analysis.

RESULTS

The most frequently identified accommodation was enrollment in special education classes in 47.7% of the charts. Other academic accommodations that were most often reported were adaptive physical education (n = 71, 39.9%), tutoring (n = 28; 15.7%), and home schooling (n = 21; 11.8%). Clean intermittent catheterization was the most frequently identified health-related accommodation provided by the school nurse/aide (n = 57; 32%).The largest percentage of requests for additional accommodations were made during the middle school grades (15; 54.8%) followed by high school (10; 32.2%).

CONCLUSION

Findings demonstrated that persistent issues were identified by parents/adolescents regarding the provision of school-related accommodations. This is a relevant area for clinical practice to ensure students with special health care needs and those with spina bifida receive the academic and health-related accommodations in their Individualized Education Program/504 plans.

Medical responsibility growth in youth with spina bifida: Neuropsychological and parenting predictors

OBJECTIVE

For youth with spina bifida (SB) there is a growing need to understand how responsibilities for health care are transferred from family- to self-management over time. The current study examined trajectories of responsibility for medical tasks in youth with SB across adolescence, as well as executive functioning/attention and parenting behaviors as predictors of growth.

METHOD

As part of a larger, longitudinal study, 140 youth with SB (ages 8-15 at time 1; Mage = 11.43) reported on their responsibility for relevant medical tasks across five time points. Attention and executive functioning were assessed via performance-based and parent/teacher-report methods. Parenting behaviors consisted of acceptance, behavioral control, and psychological control and were assessed via observational and parent-report.

RESULTS

Growth curve analyses revealed significant increases in youth medical responsibility across all SB tasks over time. Attention, executive functioning, maternal behavioral control, and paternal psychological control emerged as predictors of growth parameters in responsibility for communicating about SB and managing health care appointments.

CONCLUSION

Results indicated that youth with SB obtain increasing responsibility for their health care over time. The transfer of responsibility for SB management may differ based on individual (i.e., the child's neuropsychological abilities) and family level (i.e., parenting behaviors) factors. Further research is needed to understand how growth in medical responsibility relates to changes in other aspects of SB self-management across development, such as medical adherence.

[Formula: see text]Neurocognitive predictors of adaptive functioning trajectories among youth with spina bifida

Little is known about how youth with spina bifida (SB) acquire adaptive functioning skills across development. Therefore, the current study examined: (1) trajectories of adaptive functioning in youth with SB as they transitioned from childhood into adolescence, and (2) neuropsychological functioning as a potential risk factor for long-term adaptive functioning difficulties. Participants (n = 131 youth with SB) were recruited as part of a larger ongoing longitudinal study. Growth curves were used to examine changes over time across six adaptive functioning skills: communication, self-direction, functional academics, social, self-care, and home living skills. Additionally, youth's attention and executive functioning (i.e., working memory, planning/organizational skills, cognitive flexibility, inhibition) were assessed via questionnaires and performance-based assessments, and entered as predictors in the models. Youth's communication, self-direction, functional academics, self-care, and home living skills increased over time across age, whereas youth's social skills did not. Scaled scores for youth's social, communication, self-direction, and functional academics skills were generally within normal limits, whereas those for self-care and home living skills fell in the borderline range. Better attention and executive functioning predicted a higher intercept for many adaptive functioning abilities at 11.5 years old, above and beyond the influence of IQ. However, these variables did not predict growth in adaptive functioning. Results indicate that youth with SB acquire skills across development to better meet the demands of daily life. However, youth with poorer neurocognitive functioning may demonstrate adaptive functioning deficits in early childhood and benefit from timely intervention.

Variables Associated With Shift of Responsibility for Daily Tasks From Parents to Children With and Without Disabilities

IMPORTANCE

No study has directly investigated which variables are associated with the shift of responsibility for managing daily tasks from parent to child in the transition to adulthood.

OBJECTIVE

To examine characteristics associated with responsibility for managing daily life tasks in youth with and without disabilities.

DESIGN

A secondary data analysis of parent-report data on typically developing (TD) youth and youth with disabilities.

SETTING

An online panel that has regularly participated in online surveys.

PARTICIPANTS

A nationally representative sample of 2,205 TD U.S. children and youth, ages 0 to 20 yr, 11 mo (about 100 children per age year) and a sample of 617 children and youth with disabilities, ages 0 to 20 yr, 11 mo.

OUTCOMES AND MEASURES

The dependent variable was the Responsibility domain scaled score (from the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test), which reflects the extent to which responsibility for daily tasks has shifted from parent to youth.

RESULTS

Youth with higher levels of responsibility were older in age, reported to be more focused, and youngest in birth order (TD, R 2 = .79; disability, R 2 = .35). Youth with developmental delay, intellectual disability, autism spectrum disorder, or orthopedic or movement impairments had assumed less responsibility.

CONCLUSIONS AND RELEVANCE

Other personal characteristics in addition to disability may have important influences on parents' decision making as they prepare their children to manage daily life tasks.

WHAT THIS ARTICLE ADDS

Clinicians who work with adolescents in the process of transition to adulthood need to consider the potential influence of the personal characteristics, such as birth order and child temperament, on preparation for adulthood.

Longitudinal associations between neuropsychological functioning and medical responsibility in youth with spina bifida: The moderational role of parenting behaviors

For youth with spina bifida (SB), the transfer of medical responsibilities from parent- to self-management is an important component of autonomy development. Youth with SB are at risk for neurocognitive impairments with inattention and executive dysfunction, which may impact their ability to take responsibility for medical tasks. However, adaptive parenting may buffer against the negative impact of executive/attentional dysfunction on levels of medical responsibility. Thus, this study examined the moderating roles of parenting behaviors and child age on the longitudinal associations between neuropsychological functioning and medical responsibility in youth with SB. Participants were recruited as part of a larger, longitudinal study. Youth with SB (N = 89, Mage = 11.10 years) completed a neuropsychological battery of executive functioning and attention measures at Time 1 (T1). Parents reported on youth's executive functioning/attention skills at T1, and child medical responsibility two years later at Time 2 (T2). Observational methods were used to assess parenting behaviors (warmth, behavioral and psychological control) at T1. Attention and cognitive shifting skills at T1 were positively related to child medical responsibility at T2. Two-way interactions between planning/organizing skills and paternal acceptance, and planning/organizing skills and paternal psychological control, were found. A three-way interaction between cognitive shifting skills, maternal acceptance, and child age was found. When conceptualizing risk factors for low medical responsibility in youth with SB, it is important to consider the family context beyond individual, cognitive factors. The results are discussed within the wider context of social-ecological models of medical responsibility.

A Longitudinal Study of Depressive Symptoms, Neuropsychological Functioning, and Medical Responsibility in Youth With Spina Bifida: Examining Direct and Mediating Pathways

Objective

Given the increased risk for cognitive deficits and development of depressive symptoms in youth with spina bifida (SB), this study aimed to examine two pathways through which depressive symptoms and neuropsychological dysfunction may be associated with medical autonomy in this population: (1) depressive symptoms as predictors of medical autonomy as mediated by attention/executive functioning (the cognitive scarring model), and (2) attention/executive functioning as predictors of medical autonomy as mediated by depressive symptoms (the cognitive vulnerability model).

Methods

Participants were recruited as part of a larger, longitudinal study, and included 114 youth with SB (M age = 10.96 at Time 1), their parents, and teachers. Neuropsychological constructs included attention, working memory, and planning/organizing abilities, which were measured with questionnaire and performance-based data. Depressive symptoms and medical responsibility were assessed via questionnaires from multiple respondents.

Results

Bootstrapped mediation analyses revealed that teacher-reported depressive symptoms significantly mediated the relations between neuropsychological functioning (i.e., attention and working memory) and medical responsibility (all p's < .05); neuropsychological dysfunction did not mediate the relationship between depressive symptoms and medical responsibility.

Conclusions

One way in which neurocognitive dysfunction may hinder the development of medical autonomy in youth with SB is through an increased risk for depressive symptoms.

Cultural Considerations for Autonomy and Medical Adherence in a Young Palestinian American Muslim Female With Spina Bifida: A Longitudinal Case Study in a Research Context

This case study examines the unique presentation of a young Palestinian-American Muslim female, who is a part of an ongoing longitudinal study examining family and peer relationships, psychological adjustment, and neuropsychological functioning in youth with spina bifida. Throughout ten years of data collection, Palestinian-Arab culture and Islamic faith have consistently emerged as important factors that can be considered when interpreting this participant's general level of autonomy, medical autonomy, medical adherence, and psychological adjustment. This case study examines important aspects of adaptive and independent functioning for youth with spina bifida and how this family's culture interacts with these different domains of functioning. Moreover, it explores potential conflicts between an Arab collectivist family structure and Western biomedical ethics and suggests how clinicians might navigate these conflicts and bolster culturally-rooted strengths of families and patients from non-Western backgrounds.

Potential benefits of the cognitive orientation to daily occupational performance approach in young adults with spina bifida or cerebral palsy: a feasibility study

Purpose: People with cerebral palsy (CP) or spina bifida (SB) often struggle to perform everyday-life activities. Both groups frequently also have difficulties in creating and using strategies effectively when performing tasks. The cognitive orientation to daily occupational performance (CO-OP) Approach combines the learning of cognitive strategies with task-specific approaches through a client-centred procedure. The aim of this study was to investigate whether the CO-OP Approach is feasible for and potentially beneficial to adolescents and young adults with CP or SB in Sweden by analysing four areas of feasibility (acceptability, efficacy, adaptation, and expansion).Methods: Exploratory multiple-case study using mixed methods. Ten persons aged 16-28, five with each condition, participated in an intervention period. Assessments were performed on three occasions: baseline, post-intervention, and six-month follow-up.Results: The result demonstrates that the CO-OP Approach has the potential to enable adolescents and young adults with either condition to achieve personal goals and to enhance their planning skills and their ability to use strategies when performing activities. This approach is also compatible with the core values of habilitation in Sweden and was found by the participants to be highly meaningful and useful.Conclusions: The CO-OP Approach is feasible for adolescents and young adults with SB or CP in Sweden.Implications for rehabilitationThe Cognitive Orientation to daily Occupational Performance• is a feasible approach for adolescents and young adults with spina bifida and with cerebral palsy.• is a promising approach when it comes to enabling the achievement of personal goals.• might have potential to enhance executive functioning through strategy use.• is in line with the fundamental core values of disability rights of inclusion, empowerment, and participation.

Topical Review: Integrating Findings on Direct Observation of Family Communication in Studies Comparing Pediatric Chronic Illness and Typically Developing Samples

Objective

To review research on observed family communication in families with children with chronic illnesses compared with families with healthy, typically developing children, and to integrate findings utilizing a unifying family communication framework.

Method

Topical review of studies that have directly observed family communication in pediatric populations and included a typically developing comparison group.

Results

Initial findings from 14 studies with diverse approaches to quantifying observed family communication suggest that families with children with chronic illnesses may demonstrate lower levels of warm and structured communication and higher levels of hostile/intrusive and withdrawn communication compared with families with healthy, typically developing children.

Conclusion

An integrative framework of family communication may be used in future studies that examine the occurrence, correlates, and mechanisms of family communication in pediatric populations.

ADHD and Attention Problems in Children With and Without Spina Bifida

Objectives: To identify differences in the diagnosis and treatment of attention deficit/hyperactivity disorder (ADHD) between typically developing children and children with spina bifida. Method: Sixty-eight children with spina bifida and 68 demographically matched, typically developing children participated in a larger, longitudinal study. Rates of maternal, paternal, and teacher reports of attention problems, as well as rates of maternal reports of ADHD diagnosis, diagnosing provider, pharmaceutical treatment, mental health treatment, and academic accommodations were obtained at 5 time points over a period of 8 years and were compared across groups. Results: Children with spina bifida were more likely to have an ADHD diagnosis and attention problems. Attention problems and ADHD diagnoses were first reported at earlier time points for children with spina bifida than typically developing children. Among children with ADHD or attention problems, children with spina bifida were more likely to be treated with medication, but they were just as likely to use mental health services and receive resource services at school. Conclusions: Children with spina bifida were diagnosed with ADHD and identified as having attention problems more frequently and at an earlier age. This finding could be due to earlier symptom development, greater parental awareness, or more contact with providers. Among those with ADHD or attention problems, stimulant medication was more likely to be prescribed to children with spina bifida, despite research that suggests it may not be as beneficial for them. Further research on the effectiveness of ADHD pharmacological treatment for children with spina bifida is recommended.

Daily time management in children with spina bifida

PURPOSE

Spina bifida (SB) often results in a complex disability and can also cause cognitive dysfunction. No previous study has investigated the ability to adapt to time in children with SB. This ability is crucial for an individual's possibility to develop autonomy in life. The purpose of this study was to investigate whether children aged 10-17 with SB have lower time-processing abilities than typically-developing children, and to describe the profile of time-processing in children with SB.

METHOD

Participants comprised a consecutive sample of 21 children (drawn from a geographical cohort of 45) aged 10-17 years (mean: 14 years, SD: 2 years); 13 were boys. The instruments used were KaTid-Y, Time-S, and Time-P.

RESULTS

The children with SB had lower time-processing abilities than typically-developing children (52.4% under -2SD), particularly difficulties to orient to and to estimate objective time, to understand time perspectives and with time planning. They also self-rated low use of strategies to adapt to time. The parents rated their children as having extensive difficulties in daily time management.

CONCLUSIONS

The low time-processing ability found in children with SB is likely to be an important contributing factor to low autonomy and independence.

Social Skills in Youth With Spina Bifida: A Longitudinal Multimethod Investigation Comparing Biopsychosocial Predictors

Objective

To examine the relative contributions of neuropsychological (attention and executive function), family (cohesion and conflict), and health (body mass index, lesion level, gross motor function) domains on social skills over time in youth with spina bifida (SB).

Methods

In all, 140 youth with SB (T1 mean age = 11.43 years) and their families participated in the study at baseline with an additional visit 2 years later. Study variables were assessed with multiple methods (questionnaire, medical chart review, observation, neuropsychological tests) and reporters (parents, teachers). Multivariate hierarchical linear regressions determined the predictive power of the three domains for T2 social skills.

Results

Neuropsychological variables accounted for significant variance in mother- and father-reported T2 social skills. Neither family nor health variables contributed significantly to later social skills when other domains were included in the model.

Conclusions

Neuropsychological factors are particularly important for social skill development in youth with SB. Findings can inform screening and intervention practices.

Profiles of Neuropsychological Functioning in Children and Adolescents with Spina Bifida: Associations with Biopsychosocial Predictors and Functional Outcomes

OBJECTIVES

The current study examined neuropsychological performance among children with spina bifida (SB) to determine biological and functional correlates of distinct "profiles" of cognitive functioning.

METHODS

A total of 95 children with SB myelomeningocele (ages, 8-15 years) completed a neuropsychological assessment battery. Hierarchical and non-hierarchical cluster analyses were used to identify and confirm a cluster solution. Hypothesized predictors of cluster membership included lesion level, number of shunt surgeries, history of seizures, age, ethnicity, socio-economic status, and family stress. Outcomes included independence, academic success, expectations for the future, and quality of life.

RESULTS

Ward's cluster method indicated a three-cluster solution, and was replicated with two other cluster analytic methods. The following labels were applied to the clusters: "average to low average" (n=39), "extremely low to borderline" (n=27), and "broadly average with verbal strength" (n=29). Socio-econimc status, lesion level, and seizure history significantly predicted group membership. Cluster membership significantly predicted independence, academic success, parent expectations for the future, and child reported physical quality of life.

CONCLUSIONS

Findings from this study suggest qualitatively different cognitive profiles exist among children with SB, and the relevance of neuropsychological functioning for day-to-day adaptive functioning and quality of life. Clinical implications and future research are discussed. (JINS, 2016, 22, 804-815).

Gray matter integrity within regions of the dorsolateral prefrontal cortical-subcortical network predicts executive function and fine motor dexterity in spina bifida

OBJECTIVES

This study examined microstructural properties of cortical and subcortical gray matter components of the dorsolateral prefrontal (DLPFC) cortical-subcortical circuit in relation to parent-rated executive function and fine motor dexterity performance in youth with spina bifida myelomeningocele (SBM). Aberrant gray matter integrity of the DLPFC, basal ganglia nuclei, and thalamus were hypothesized to differentially relate to neurobehavioral outcomes.

METHODS

Forty-nine youth between 8 and 18 years (M = 12.34) old with SBM underwent a 3T MRI including diffusion tensor imaging. Neurobehavioral measures of parent-rated executive function and fine motor dexterity were obtained from a standardized neuropsychological evaluation. Relations among indices of gray matter microstructural integrity (mean diffusivity [MD], fractional anisotropy [FA], cortical thickness) and neurobehavior were examined using 3 correlational methods to enhance reliability of brain-behavior relations.

RESULTS

In SBM, higher FA values in the caudate were associated with poorer behavioral regulation. Higher FA values in the putamen and greater DLPFC thickness were both associated with poorer fine motor dexterity.

CONCLUSION

Behavioral regulation and FA in the caudate related to behavioral inhibition in SBM. Similarly, associations between fine motor dexterity and indices of gray matter integrity in the putamen and DLPFC support fronto-striatal involvement in motor control in SBM. Examination of these neurobehavioral correlates revealed a pattern of attenuated behavioral impairments when gray matter structure was more similar to that of typically developing youth.

Experiences among children and adolescents of living with spina bifida and their visions of the future

Purpose Transitioning to independence may be problematic for persons with spina bifida (SB). Experiences of young persons with SB may provide insights into this group's needs for support. Therefore, the aim of this study was to investigate children's and adolescents' experiences of living with SB, their social and emotional adjustment, and their thoughts about becoming independent adults. Method Semi-structured interviews were conducted with young persons with SB (N = 8, age range 10-17 years). Social and emotional problems were assessed using Beck Youth Inventories. The interview transcripts were analyzed using qualitative content analysis. Results Three main themes were found: being a person with SB; everyday living as a person with SB; and preparing for life as an adult with SB. Indications of emotional and social problems were most prominent among participants with milder physical disability. Conclusions The findings indicate that young persons with SB may overestimate their independence. Other potentially problematic areas were lack of motivation, planning and preparedness for becoming independent. Research on transition to independence in this group should consider assistance at an early age in planning and executing strategies for independence. In addition, the potentially difficult situation for young persons with mild SB should be investigated further. Implications for rehabilitation Children and adolescents with spina bifida might lack the motivation and skills for planning their future and health care programmes should therefore include preparations for life as an adult. Clinical assessment of the level of independence should specifically distinguish between the activities they know how to do and what tasks they actually execute independently. Routine follow-ups should include screening for problems with social and emotional adjustment. Be aware of a potential condition-severity paradox whereby those with less severe impairment might have an increased risk of developing symptoms of social and emotional problems.

Goal Management Training improves everyday executive functioning for persons with spina bifida: self-and informant reports six months post-training

Executive dysfunction accounts for significant disability for many patients with spina bifida (SB), thus indicating the need for effective interventions aimed at improving executive functioning in this population. Goal Management Training™ (GMT) is a cognitive rehabilitation approach that targets disorganised behaviour resulting from executive dysfunction, and has received empirical support in studies of other patient groups. The purpose of this study was to determine if GMT would lead to perceived improved executive functioning in the daily lives of patients with SB, as evidenced by reduced report of dysexecutive problems in daily life on self- and informant questionnaires. Thirty-eight adults with SB were included in this randomised controlled trial (RCT). Inclusion was based upon the presence of executive functioning complaints. Experimental subjects (n = 24) received 21 hours of GMT, with efficacy of GMT being compared to results of subjects in a wait-list condition (n = 14). All subjects were assessed at baseline, post-intervention, and at six-month follow-up. Self-report measures indicated that the GMT group's everyday executive functioning improved significantly after training, lasting at least 6 months post-treatment. There were no significant effects on informant-report questionnaires. Overall, these findings indicate that executive difficulties in everyday life can be ameliorated for individuals with congenital brain dysfunction.
