Effects of Executive Functions Training in Primary School Students with Borderline Intellectual Functioning Through a Multi-Method, Multi-Informant Intervention: A Pilot Study.

Objective: Borderline Intellectual Functioning (BIF) impacts cognitive functioning and adaptive behavior. Recent studies have demonstrated the efficacy of Executive Functions trainings to support daily-living skills in several clinical populations. However, although the relationship between Executive Functions and BIF has been studied, few studies have explored the effects of cognitive enhancement training for BIF children. Given the pivotal significance of Executive Functions in learning, orchestrating cognitive processes, and modulating affective and behavioral responses, our study aimed to evaluate the efficacy of cognitive enhancement training targeting Executive Functions in a group of 23 children diagnosed with Borderline Intellectual Functioning devoid of neurodevelopmental impairments. Method: We included a multiple assessment based on several informants (children, teachers, parents, and tutors) and provided individualized cognitive enhancement training focused on Executive Functions through both digital and analog activities. The training was highly customized, structured and monitored at various stages of the process activities. The training was composed of 20 sessions, each lasting 2 hours, held twice a week for each child. Results: The obtained results confirmed the efficacy of cognitive enhancement training in improving Executive Functions, the primary target of the intervention, particularly in attention, verbal fluency, planning, inhibitory control, working memory, and flexibility. Furthermore, improvements were observed by all the informants in other cognitive functions, learning, and adaptive behaviors. Conclusions: Our study contributes to the understanding of BIF, emphasizing the efficacy of neuropsychological enhancement through personalized training for EF.

Exploring the Clinical Characteristics and Comorbid Disorders of Borderline Intellectual Functioning.

Borderline intellectual functioning (BIF) is characterized by cognitive impairment and deficits in adaptive functioning. Despite affecting a significant proportion of the population, BIF still remains underdiagnosed and poorly understood. In addition to cognitive impairments across a range of domains, individuals with BIF face a greater risk of academic failure and often require special educational support. They suffer from emotional problems, such as difficulties with emotional awareness, anxiety, depressed mood, and unhappiness. Individuals with BIF are more likely to have an impairment of social and adaptive functioning. Furthermore, individuals with BIF are at higher risk of physical and mental health problems, often receive inadequate treatment, and have a poorer prognosis. This review aims to enhance the understanding of clinicians, educators, and policymakers by providing an overview of the characteristics of BIF and its associated challenges, ultimately contributing to the improvement of support systems for individuals with BIF.

Epidemiology and Diagnosis of Slow Learners (Borderline Intellectual Functioning).

The definitions of "slow learners" and "borderline intellectual functioning (BIF)" have not reached a consensus and have continually evolved in terminology. The criteria for diagnosing BIF include the Full-Scale Intelligence Quotient, adaptive functioning, and onset of symptoms from the developmental period; however, specific standards have not been provided. Until the Diagnostic and Statistical Manual of Mental Disorders-IV, a range for the Full-Scale Intelligence Quotient was provided, but due to its limitations in reflecting the actual functioning of individuals with BIF, this criterion was removed from the Diagnostic and Statistical Manual of Mental Disorders-5. The absence of specific diagnostic criteria complicates the identification of individuals with BIF, highlighting the need for a more precise classification and definition.

Etiology of Borderline Intellectual Functioning.

Borderline intellectual functioning (BIF), characterized by intelligence quotient scores between 70 and 85, can lead to challenges in daily life. This review explored the multifaceted nature of BIF by examining the interplay between genetic predisposition, prenatal/perinatal factors, environmental influences, and underlying medical conditions.

Factors affecting the feelings of safety among individuals with mild intellectual disabilities and severe challenging behaviour in residential care: A qualitative study of professional and service users' perspectives.

Background: This study focuses on what feeling safe means for people with mild intellectual disabilities and severe challenging behaviour, and which factors affect their sense of safety. Method: Thematic analysis was used to analyse data collected during (1) ethnographic longitudinal research and (2) interviews and focus groups among professionals and service users. Results: Feelings of safety can relate to three main themes: (1) a physical environment that reduces risks and temptations; (2) a reliable, predictable, and supportive environment; and (3) an accepting environment that enables service users to establish a normal life. An analysis of which factors affect service users' sense of safety identified 20 themes (e.g. team climate) and 34 subthemes (e.g. interactions with other service users). Conclusions: A range of interconnected factors can affect service users' feelings of safety. Future research should explore what organisations and external actors (e.g. the police) can do to promote those feelings.

School-based targeted prevention for children with mild intellectual disabilities or borderline intellectual functioning and behaviour problems: A pilot implementation study.

BACKGROUND: We examined the implementation and potential effectiveness of a school-based targeted prevention programme addressing behaviour problems, adapted for children with mild intellectual disabilities or borderline intellectual functioning. METHOD: Thirteen children participated. The intervention was implemented in schools. We examined intervention dosage, reach, responsiveness, satisfaction, and comprehension, using questionnaires completed by children and trainers. We assessed child- and teacher-reported behaviour problems before and after the intervention. RESULTS: Trainers selected both children who did and did not meet the intervention eligibility criteria, suggesting problems in intervention reach. Intervention dosage, responsiveness, satisfaction, and comprehension were satisfactory. There were group-level behaviour problem decreases (i.e., Cohen's d). Individual-level behaviour problem changes (i.e., Reliable Change Indices) showed large heterogeneity and little reliable change. CONCLUSIONS: The results provide initial evidence that the intervention has potential for successful implementation in schools, but the current evidence for intervention effectiveness is inconclusive.

Reading comprehension differences between children with Autism Spectrum Disorder and low cognitive abilities and children with Autism Spectrum Disorder and intact cognitive skills: the roles of decoding, fluency and morphosyntax.

Introduction: Reading comprehension is one of the most important skills learned in school and it has an important contribution to the academic success of children with Autism Spectrum Disorder (ASD). Though previous studies have investigated reading comprehension difficulties in ASD and highlighted factors that contribute to these difficulties, this evidence has mainly stemmed from children with ASD and intact cognitive skills. Also, much emphasis has been placed on the relation between reading comprehension and word recognition skills, while the role of other skills, including fluency and morphosyntax, remains underexplored. This study addresses these gaps by investigating reading comprehension in two groups of school-aged children with ASD, one with intact and one with low cognitive abilities, also exploring the roles of word decoding, fluency and morphosyntax in each group's reading comprehension performance. Methods: The study recruited 16 children with ASD and low cognitive abilities, and 22 age-matched children with ASD and intact cognitive skills. The children were assessed on four reading subdomains, namely, decoding, fluency, morphosyntax, and reading comprehension. Results: The children with ASD and low cognitive abilities scored significantly lower than their peers with intact cognitive abilities in all reading subdomains, except for decoding, verb production and compound word formation. Regression analyses showed that reading comprehension in the group with ASD and intact cognitive abilities was independently driven by their decoding and fluency skills, and to a lesser extent, by morphosyntax. On the other hand, the children with ASD and low cognitive abilities mainly drew on their decoding, and to a lesser extent, their morphosyntactic skills to perform in reading comprehension. Discussion: The results suggest that reading comprehension was more strongly affected in the children with ASD and low cognitive abilities as compared to those with intact cognitive skills. About half of the children with ASD and intact cognitive skills also exhibited mild-to-moderate reading comprehension difficulties, further implying that ASD may influence reading comprehension regardless of cognitive functioning. Finally, strengths in decoding seemed to predominantly drive cognitively-impaired children's reading performance, while the group with ASD and intact cognitive skills mainly recruited fluency and metalinguistic lexical skills to cope with reading comprehension demands, further suggesting that metalinguistic awareness may be a viable way to enhance reading comprehension in ASD.

Dog-Assisted Therapy in Mental Health Care: A Qualitative Study on the Experiences of Patients with Intellectual Disabilities.

(1) Background: Dog-assisted therapy (DAT) is an experiential intervention to promote psychological, physical, and social functioning in children and adults. Only few studies have been conducted on DAT in adults with a mild intellectual disability or borderline intellectual functioning (MID-BIF). The purpose of this study was to explore the experiences of patients with MID-BIF undergoing DAT in a mental health care facility. (2) Method: Seven patients completed 13 to 15 sessions of DAT. Within two weeks of completing the program, they were interviewed using a semi-structured interview. The transcripts of the interviews were analysed using interpretational phenomenological analysis. In addition, the patients' relatives and the DAT therapist were interviewed, and a focus group discussion took place with each patient's treatment team. (3) Results: The patients' experiences were predominantly positive. Physical contact with the dog calmed them down. The dog offered them emotional support and helped them to make contact inside and outside the therapy and the setting where they lived. The patients also liked the fact that DAT focused on the dog rather than their problems, that the therapy was experiential and using a positive approach, and that, during the therapy, they did not feel like a patient but a human being. DAT is a promising therapy for patients with MID-BIF in mental health care facilities, but more research into its effectiveness and cost-effectiveness and ways to implement DAT in clinical practice is needed to make more definitive statements.

Comprehensive analyses of neurodevelopmental outcomes and quality of life of children with biliary atresia.

OBJECTIVES: To holistically evaluate neurodevelopmental outcomes and quality of life (QOL) of Japanese patients with biliary atresia (BA) and to investigate the factors associated with the outcomes. METHODS: This study enrolled patients with BA aged 5-18 years who visited Osaka University Hospital in 2021. Neurodevelopmental assessments were performed to evaluate intellectual ability, cognitive functions and adaptive skill levels. Furthermore, emotional and behavioral issues, characteristics of attention deficit hyperactivity disorder, and QOL were concomitantly assessed in the same cohort. Biochemical and social factors associated with the results were examined. RESULTS: Fifty-three patients, with a median age of 11.2 years were included in the analyses. Patients with BA had a significantly lower Full-Scale Intelligence Quotient or developmental quotient (FSIQ/DQ) score and Vineland Adaptive Behavior Scale (VABS) composite score than the general Japanese population. Household education level and short stature were associated with low and borderline FSIQ/DQ and VABS composite scores, respectively. Among patients with low and borderline FSIQ/DQ scores, those with average or high VABS composite scores received significantly less neuroeducational care than those with low and borderline VABS composite scores. Despite the low FSIQ/DQ and VABS composite scores, the total QOL scores were higher than those of the general population. CONCLUSION: Patients with BA had intellectual and behavioral impairments. Notably, patients with intellectual impairments are overlooked and not followed up, especially if adaptive skills are maintained.

Intellectual development in young children with autism spectrum disorders: A longitudinal study.

Intelligence profiles in autism have been characterized by great variability. The questions of how autistic children's intelligence changes over time, and what factors influence these changes deserve study as part of efforts to document child autism profiles, but also because the relationship between intellectual functioning and children's background characteristics is poorly understood, particularly in a longitudinal context. A total of 39 autistic children and 39 age-matched neurotypical children (5-9 years old) completed two IQ assessments at preschool age and up to 4 years later. Repeated-measures analyses assessed longitudinal changes in the children's verbal (VIQ), performance (PIQ), and full-scale IQ (FSIQ) at group level. We further sought to identify clusters with distinct profiles in each group by adopting an unsupervised K-means clustering approach, and detect possible between-subgroup differences in terms of children's socioeconomic status and autism severity. The largest cluster in the autistic group was composed of children whose PIQ significantly dropped at follow-up, while the second largest cluster improved in all quotients; the smallest cluster, wherein children had more highly educated mothers than the rest of the clusters, was characterized by large improvement in VIQ. For the neurotypical children, there was a two-cluster division; the majority of them improved in the three quotients, while very few dropped in PIQ at follow-up. The relation between socioeconomic status and IQ changes was significant for both groups. The findings demonstrate both the complexity of intelligence changes in autism and the need to view this complexity through the lens of the children's socioeconomic diversity.

Psychometric analysis of the Group Climate Inventory-Revised in adults with mild intellectual disability or borderline intellectual functioning in a secure residential facility.

BACKGROUND: In secure residential facilities, group climate perceptions of clients with mild intellectual disability or borderline intellectual functioning are systematically assessed for quality improvement. A valid and reliable measure may ensure that this process is consistent. The Group Climate Inventory-Revised (GCI-R) is a new measure to assess group climate perceptions. METHOD: Confirmatory factor analysis was conducted in 148 adult clients (79% male) with mild intellectual disability or borderline intellectual functioning in a secure facility to examine internal structure validity and internal consistency reliability of the GCI-R. RESULTS: The results indicate support for the five-factor structure of the GCI-R ('Support', 'Growth', 'Repression', 'Peer interactions', and 'Physical environment'). The internal consistency reliability of its scales ranged from acceptable to good (α: .72-.87; ω: .76-.86). CONCLUSION: The GCI-R demonstrates evidence of psychometric adequacy when applied to adult clients with mild intellectual disability or borderline intellectual functioning in secure residential facilities.

Mental health and service use of parents with and without borderline intellectual functioning.

BACKGROUND: People with borderline intellectual functioning (BIF) encounter greater social adversities than the general population and have an increased prevalence of mental illness. However, little is known about the socio-demographic characteristics and mental health of parents with BIF. METHODS: A secondary data analysis of the Adult Psychiatric Morbidity Survey 2014 was conducted. Logistic regression models were fitted to compare differences in socio-demographic, mental health and service-use characteristics between parents and non-parents with and without BIF, and to investigate if the relationship between parent status and mental health outcomes was modified by BIF status, sex, and employment. RESULTS: Data from 6872 participants was analyzed; 69.1% were parents. BIF parents had higher odds of common mental disorder, severe mental illness, post-traumatic stress disorder, self-harm/suicide and were more likely to see their General Practitioner (GP) and to receive mental health treatment than non-BIF parents. BIF parents did not have a higher prevalence of mental health problems than BIF non-parents. Being a parent, after adjusting for BIF status and other confounders, was associated with increased odds of having a common mental disorder, visits to see a GP and treatment for mental health. Female parents had higher odds of treatment for mental health problems. CONCLUSIONS: Being a parent is associated with elevated rates of common mental disorders. There is a higher burden of mental health problems and service use in people with BIF. A greater provision of specialist support services including ascertainment is indicated for this group.

Premorbid intelligence quotient and school failure as risk markers for bipolar disorder and major depressive disorder.

Mood disorders significantly impact global health, with MDD ranking as the second leading cause of disability in the United States and BD ranking 18th. Despite their prevalence and impact, the relationship between premorbid intelligence and the subsequent development of BD and MDD remains inconclusive. This study investigates the potential of premorbid Intelligence Quotient (IQ) and school failure frequency as risk factors for Bipolar Disorder (BD) and Major Depressive Disorder (MDD) in a birth cohort setting. We analyze data from the Pelotas population-based birth cohort study, comprising 3580 participants aged 22, who had no prior mood disorder diagnoses. Utilizing regression models and accounting for potential confounders, we assess the impact of IQ and school failure, measured at age 18, on the emergence of BD and MDD diagnoses at age 22, using individuals without mood disorders as comparators. Results reveal that lower IQ (below 70) at 18 is associated with an increased risk of BD (Adjusted Odds Ratio [AOR] 1.75, 95%CI: 1.00-3.09, p < 0.05), while higher IQ (above 120) is linked to MDD (AOR 2.16, 95%CI: 1.24-3.75, p < 0.001). Moreover, an elevated number of school failures is associated with increased BD risk (AOR 1.23, 95%CI: 1.11-1.41, p < 0.001), particularly for BD type 1 (AOR 1.36, 95% CI: 1.17-1.58, p < 0.001). These findings offer insights into the distinct premorbid intellectual characteristics of BD and MDD and contribute to a deeper understanding of their developmental trajectories, potentially informing the development of risk assessment tools for mood disorders.

Measurement invariance of the group climate inventory across adults with and without mild intellectual disability in secure residential facilities.

BACKGROUND: The Group Climate Inventory (GCI) was tested for measurement invariance across 332 adults with and 225 adults without mild intellectual disabilities in Dutch forensic treatment, and for latent mean differences on its Support, Growth, Repression, and Atmosphere subscales. METHOD: Multigroup confirmatory factor analysis was used to evaluate the configural, threshold, and loading and threshold invariance of the GCI across both groups, and to compare group latent means on each subscale. RESULTS: Measurement invariance was found across groups. Latent mean group comparisons showed small but significant differences reflected in lower scores on Support and Atmosphere in the group with mild intellectual disabilities. CONCLUSION: The GCI allows meaningful comparisons between clients with and without mild intellectual disabilities in secure facilities. Results from the between-group comparisons suggest that consideration should be given as to whether, and why, the support and atmosphere perceptions of clients with mild intellectual disabilities might be less good.

Predicting neuropsychological late effects in pediatric brain tumor survivors using the Neurological Predictor Scale and the Pediatric Neuro-Oncology Rating of Treatment Intensity.

OBJECTIVE: The Neurological Predictor Scale (NPS) quantifies cumulative exposure to tumor- and treatment-related neurological risks. The Pediatric Neuro-Oncology Rating of Treatment Intensity (PNORTI) measures the intensity of different treatment modalities, but research is needed to establish whether it is associated with late effects. This study evaluated the predictive validity of the NPS and PNORTI for neuropsychological outcomes in pediatric brain tumor survivors. METHOD: A retrospective chart review was completed of pediatric brain tumor survivors (PBTS) (n = 161, Mage = 13.47, SD = 2.80) who were at least 2 years from the end of tumor-directed treatment. Attention, intellectual functioning, perceptual reasoning, processing speed, verbal reasoning, and working memory were analyzed in relation to the NPS and PNORTI. RESULTS: NPS scores ranged from 1 to 11 (M = 5.57, SD = 2.27) and PNORTI scores ranged from 1 (n = 101; 62.7%) to 3 (n = 18; 11.2%). When controlling for age, sex, SES factors, and time since treatment, NPS scores significantly predicted intellectual functioning [F(7,149) = 12.86, p < .001, R2 = .38] and processing speed [F(7,84) = 5.28, p < .001, R2 = .31]. PNORTI scores did not significantly predict neuropsychological outcomes. CONCLUSIONS: The findings suggest that the NPS has value in predicting IF and processing speed above-and-beyond demographic variables. The PNORTI was not associated with neuropsychological outcomes. Future research should consider establishing clinical cutoff scores for the NPS to help determine which survivors are most at risk for neuropsychological late effects and warrant additional assessment.

Developing a recovery-oriented intervention for people with severe mental illness and an intellectual disability: design-oriented action research.

Introduction: Mild intellectual disability or borderline intellectual functioning (MID/BIF) are common in people with severe mental health problems (SMHP). Despite this, there is a lack of treatments adapted for this group of clients. Methods: This qualitative study describes the development of a new intervention, guided by the principles of action research, for people with SMHP and MID/BIF and mental health professionals to help them talk about all aspects of the process of recovery. The intervention was developed in four cycles and in close cooperation with mental health professionals, experts by experience, other experts in the field of SMHP or MID/BIF, and clients. During all cycles there was a strong focus on the content of the intervention, exercises, understandable language, and drawings for visual support. Results: This resulted in the intervention "Routes to Recovery," which covers both complaints and strengths, coping strategies, helpful (social) activities, and how to determine future steps in a recovery plan. Discussion: Routes to Recovery is a first step in helping professionals and their clients with SMHP and MID/BIF to have a conversation about personal strengths and what the client needs to recover. Future research should investigate the effects of this intervention.

Dialectical behavior therapy-skills system for cognitively challenged individuals with self-harm: a Swedish pilot study.

Background: Dialectical behavior therapy (DBT) is an evidence-based treatment for self-harm and emotion regulation difficulties. A modified version, DBT-Skills System (DBT-SS), has been developed in the USA for individuals with cognitive difficulties. The present study is a pilot study, testing the DBT-SS in a Swedish context. Methods: Six participants were treated with individual therapy and group skills training for 48 sessions each. A case series design was used to follow individual development over time. The primary outcome measure was reduction in challenging behaviors. Secondary outcomes were level of functioning in daily life, hospital admissions, and resilience and vulnerabilities in different risk domains. Data was analyzed using time-series diagrams. Effect sizes of changes were calculated using Cohen's d. Results: Challenging behaviors decreased over time and participants' global level of functioning increased. There was a reduction in number of hospital admissions over time. As for resilience and vulnerabilities, participants' overall level of risk in various areas remained unchanged or decreased after treatment. Conclusions: The results indicate that DBT-SS might be a promising treatment for cognitively challenged individuals with emotion regulation difficulties and challenging behaviors in a Swedish context. The study provides suggestions for a future randomized controlled trial. Supplemental data for this article is available online at here.

Association Between Intellectual Functioning and Autistic Traits in the General Population of Children.

Autistic traits are continuously distributed in the general population. The associations between autistic traits and intellectual functioning and/or behavioural difficulties, and the impact of intellectual functioning on behavioural difficulties are unclear. The study aims to describe the distribution of autistic traits in a population-based cross-sectional sample of children. Further aims are to examine the association between intellectual functioning and autistic traits, and between autistic traits and behavioural difficulties. Wechsler scales and ratings of autistic traits and behavioural problems in 874 children aged 7-9 years in the Swedish Environmental Longitudinal Mother and Child, Asthma and Allergy (SELMA) study were assessed. We found a continuous distribution of autistic traits. Intellectual functioning was negatively associated with autistic traits but not with behavioural difficulties. Behavioural difficulties were associated with autistic traits.

Experienced support at work, team climate and collaboration in teams working with people with mild intellectual disabilities and severe challenging behaviour in residential care: a cross-sectional study.

BACKGROUND: This study explored the perceptions of staff for people with mild intellectual disabilities or borderline intellectual functioning and severe challenging behaviour in relation to the support they received at work from four groups of professionals (i.e. team leaders, managers, psychologists and other staff members). The team climate, such as the workplace having clearly defined goals for staff, was also explored. In addition, the associations between the support from each of the professionals and team climate with the well-being and job satisfaction of staff were examined. We hypothesised that staff would perceive higher levels of support from professionals around a team (i.e. team leaders, managers and psychologists) and a more positive team climate when professionals around a team experience more positive mutual collaboration. METHODS: An online questionnaire about support at work, team climate, well-being and job satisfaction was completed by 201 staff members from 32 teams at 10 residential service organisations. In addition, professionals surrounding these teams rated their mutual collaboration. RESULTS: Both support received at work from all four groups of professionals and team climate showed significant small to moderate positive associations with job satisfaction. Well-being was associated with support from team leaders, psychologists and other staff members in the team, as well as with team climate. We did not find support for the hypotheses that staff would perceive higher levels of support or a more positive team climate when professionals around a team experience more positive mutual collaboration. CONCLUSIONS: This study highlights the importance of investing in staff support and creating a positive team climate for promoting staff well-being and job satisfaction. Implications for future research regarding staff support, team climate and the collaboration between professionals around a team are discussed.
