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.

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.

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.

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.

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.

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.

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.

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.

Social information processing, normative beliefs about aggression and parenting in children with mild intellectual disabilities and aggressive behavior.

BACKGROUND: High levels of aggressive behavior in children with mild intellectual disabilities to borderline intellectual functioning (MID-BIF) are associated with deviant social information processing (SIP) steps. The current study investigated deviant SIP as a mediating mechanism linking both children's normative beliefs about aggression and parenting to aggressive behavior in children with MID-BIF. Additionally, the mediating role of normative beliefs about aggression in linking parenting and deviant SIP was investigated. METHODS: 140 children with MID-BIF in community care in the Netherlands, their parent(s) or caretaker(s), and their teacher participated in this cross-sectional study. Structural equation modeling was performed to test mediations. Models were run separately for parent and teacher reports of aggression, and included three deviant SIP steps (interpretation, response generation, response selection). RESULTS: A total indirect effect through deviant SIP steps was found from normative beliefs about aggression to teacher-reported aggression, but not to parent-reported aggression. An indirect effect was found from positive parenting through normative beliefs about aggression to deviant SIP. CONCLUSION: The results of this study suggest that, next to deviant SIP and parenting, normative beliefs about aggression may be a relevant intervention target for children with MID-BIF and aggressive behavior.

Relationships between dynamic risk factors for externalising problem behaviour and group climate in adults with mild intellectual disability in forensic treatment.

BACKGROUND: Relationships between dynamic risk factors for externalising problem behaviour and group climate were investigated in 151 adult in-patients with mild intellectual disability or borderline intellectual functioning in a Dutch secure residential facility. METHOD: Regression analysis was used to predict total group climate score and Support, Growth, Repression, and Atmosphere subscales of the 'Group Climate Inventory'. Predictor variables were Coping Skills, Attitude towards current treatment, Hostility, and Criminogenic attitudes subscales of the 'Dynamic Risk Outcome Scales'. RESULTS: Less hostility predicted a better overall group climate, better support and atmosphere, and less repression. A positive attitude towards current treatment predicted better growth. CONCLUSION: Results indicate relationships of hostility and attitude towards current treatment with group climate. A focus on both dynamic risk factors and group climate may provide a basis for improving treatment for this target group.

The predictive value of the dynamic risk outcome scales (DROS) for recidivism in (forensic) clients with mild intellectual disabilities or borderline intellectual functioning.

BACKGROUND: The dynamic risk outcome scales (DROS) was developed to assess treatment progress of clients with mild intellectual disability or borderline intellectual functioning using dynamic risk factors. We studied the predictive value of the DROS on various classifications and severity levels of recidivism. METHOD: Data of 250 forensic clients with intellectual disabilities were linked to recidivism data from the Judicial Information Service in the Netherlands. Receiver operating characteristics (ROC) analyses were used to determine the predictive values. RESULTS: The DROS total score could not significantly predict recidivism. A DROS recidivism subscale predicted general, violent and other recidivism. These predictive values were comparable to those of a Dutch tool validated for risk assessment in the general forensic population. CONCLUSIONS: The DROS recidivism subscale predicted various classifications of recidivism better than chance. At present, the DROS appears to have no added value beyond the HKT-30 for the purpose of risk assessment.

The adaptive ability performance test (ADAPT): A factor analytic study in clients with intellectual disabilities.

BACKGROUND: The adaptive ability performance test (ADAPT) was developed to assess adaptive skills in individuals with intellectual disabilities and borderline intellectual functioning, with or without mental disorders. As a follow-up to earlier research on the ADAPT, a factor analytic study was conducted. METHOD: One thousand and sixty six ADAPTs from clients with (suspected) intellectual disabilities or borderline intellectual functioning and 129 ADAPTs from participants from the general population were collected along with other characteristics (e.g., IQ, psychiatric classifications, living situation). RESULTS: An exploratory factor analysis (EFA) was performed and resulted in good fit indices. Subsequent confirmatory factor analysis (CFA) and multigroup CFA showed acceptable to good fit indices. This resulted in an instrument with eight factors and 62 items. CONCLUSION: Factor analytic results suggest that the ADAPT is a valid instrument that measures adaptive skills in individuals with intellectual disabilities or borderline intellectual functioning.

Challenges and Neuropsychological Functioning in Children and Adolescents with Borderline Intellectual Functioning.

This retrospective chart review study sought to explore neuropsychological profiles, neuropsychiatric and psychiatric comorbidity, changes in diagnoses, support at daycare and school, medication use, psychiatric referrals, and progression into further education in a cohort of participants with borderline intellectual functioning (BIF). Additionally, developmental factors connected to BIF were studied. Delays in language and gross motor development were the initial reasons for the parents to seek health care. Comorbid neuropsychiatric and psychiatric diagnoses were frequent, a total of 41% of participants were referred to psychiatric services, and 45% used medication. Educational support was needed by 92% of the study participants. The majority of those graduating elementary school continued their studies at ordinary or special vocational schools. The risk of dropping out during secondary studies appeared to increase. The results in most of the neuropsychological subdomains declined over time, and 23% of the participants were later diagnosed with an intellectual disability (ID). The early developmental signs pointing towards BIF and the need for prompt support were a delay in language and motor development, difficulties in executive function, a delay in learning the activities of daily living among children under school age, and difficulties in reading and arithmetic skills and abstract reasoning at school age. It is important to follow up and support individuals with BIF as their risk for being left behind in the society is increased. Also, it would be important to repeat the neuropsychological testing of cognitive and adaptive functions before graduating elementary school as to capture those who meet the ID criteria.

Children, Adolescents, and Young Adults with Borderline Intellectual Functioning: Etiological, Neurophysiological, and Mri Findings in a Cohort of 651 Patients.

This retrospective chart review study explored the etiology, use, and yield of the etiological investigations of 651 children and adolescents diagnosed with borderline intellectual functioning (BIF). Neurological, neurodevelopmental, or neuropsychiatric comorbidities were frequent, and in 23%, the BIF diagnosis evolved into an intellectual disability (ID) by the time of discharge. A primary etiological cause was found in 37.6%, the most prevalent causes being pre- or perinatal conditions, genetic syndromes/chromosomal abnormalities, fetal exposure to maternal substance use, cerebral dysgenesis, and neurological diseases. In total, 79.1% of patients went through one or more investigations during their follow-up. The best etiologic yield leading to a diagnosis in this study population was with exome sequencing, a specific gene panel, microarrays, electroneuromyography, and brain magnetic resonance imaging (MRI). Etiological investigations were performed more frequently among those children receiving an ID diagnosis. Yet, there was no statistically significant difference in the proportion of abnormal findings between the BIF and ID groups. This may mean that the current strategy for determining the need for etiological investigations or current means to gain an etiology is still indecisive. Considering that BIF is defined to include individuals performing between normal cognitive functioning and mild ID, this implies that the prevalence would be anywhere between 7 and 14%. Thus, it could be argued whether in-depth etiological investigations may be justified in cases other than ID in this age group of children over five. With these children and adolescents, the clinicians have to discern between those with a normal variation and those having major difficulties in adaptive behavior affecting everyday life in order to specify and prescribe the rehabilitation or other measures needed. We advocate for a targeted etiological search after careful history-taking and neurological examination. National guidelines that take into account the severity of developmental delay are warranted.

Phonological awareness and rapid automatized naming as predictors of early literacy skills among children with mild to borderline intellectual functioning.

The aim was to investigate the predicting role of phonological awareness (PA) and rapid automatized naming (RAN) on early literacy skills (e.g., word reading [WR] and spelling [SP]) among children with mild to borderline intellectual functioning. A total of 68 children in inclusive schools in grades 1 and 2, from 12 primary schools from Makka, classified as having intellectual disabilities (ID) of unspecified origin were chosen to participate in this study. Measures of PA and RAN were correlated with measures of WR and SP in children with mild to borderline intellectual functioning. This study advanced knowledge about the predictors (PA and RAN) of early literacy skills (WR and SP) among children with mild to borderline intellectual functioning.
