An examination of specific communication deficits in adults with profound intellectual disabilities

A systematic review of acquisition and mastery of skills taught using the Picture Exchange Communication System

The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication intervention for individuals with developmental disabilities that includes six, sequential phases of instruction. We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants mastering PECS phases, how long it took participants to master PECS phases (in trials to mastery), and what constituted mastery of PECS phases. We found most participants mastered only the first two phases of PECS, and Phases I, II, and IV showed the slowest and widest variability in trials to mastery. Moreover, participants who were taught the third PECS phase learned to select from an average array of three symbols, which may limit the range of messages they can communicate. We discuss our findings in light of a few important limitations and provide directions for future researchers along with recommendations for professionals who might consider PECS.

It's Never Too Late: Debunking Myths About Communication and Adults With Severe Disabilities

Communication infuses all dimensions and stages of life, influencing one's self-determination and quality of life. A number of empirical studies have demonstrated that people with severe disabilities continue to develop communication and language skills well into their adult years and make measurable gains when provided with appropriate communication services and supports. Several myths about age, ability, and experiences limit opportunities for persons with severe disabilities. In this paper, we confront and address these myths.

Straight from the horse's mouth: Increasing self-report in mental health assessment in individuals with intellectual disability

BACKGROUND

Mental health conditions are common among individuals with intellectual disability. Under recognition of mental health disorders leading to unmet treatment needs is common in this population. This article addresses one major contributing factor, the lack of cognitively accessible self-report measures for individuals with intellectual disability.

METHOD

In this literature-informed overview of the state of the field, we discuss the need for, and complexities of, including individuals with intellectual disability in mental health assessments.

RESULTS

With appropriate supports, many individuals with intellectual disability can respond to mental health questions. We discuss evidence-based strategies to make mental health assessments more accessible.

CONCLUSION

We highlight the need to engage individuals with intellectual disability to provide first-hand information about their health and well-being. New instruments and research procedures should be developed in partnership with individuals with intellectual disability. Self-report may be essential to advancing the science of mental health research.

Caring for Persons With Intellectual Disabilities and Challenging Behavior: Staff Experiences With a Web-Based Training Program

Background: Clear and effective communication is a prerequisite to provide help and support in healthcare situations, especially in health, and social care services for persons with intellectual disabilities, as these clients commonly experience communication difficulties. Knowledge about how to communicate effectively is integral to ensuring the quality of care. Currently, however, there is a lack of such knowledge among staff working in the disabilities sector, which is exacerbated by challenges in the competence provision in municipal health and social care services. Therefore, the aim of the study was to explore staffs' experience of web-based training in relation to their professional caring for persons with intellectual disabilities and challenging behavior. The intention is to move toward well-evaluated and proven web-based training in order to contribute to competence provision in this specific context. Methods: Fourteen semi-structured interviews were carried out with individual staff members to gather data regarding their experiences with web-based training in relation to their profession. The collected data were analyzed using qualitative content analysis with a focus on both manifest and latent content. Results: The staff's experiences with the web-based training program were presented as a single main theme: "Web-based training for staff initiates a workplace learning process by promoting reflections on and awareness of how to better care for persons with intellectual disabilities and challenging behavior." This theme contained three categories which are based on eight sub-categories. Conclusion and clinical implications: The benefits of web-based training for workplace learning could clearly be observed in the strengthening of professional care for persons with intellectual disabilities and challenging behavior. Staff members claimed to have gained novel insights about how to better care for clients as well as about the importance of interactions in their encounters with clients. Professional teamwork is crucial to providing effective care for persons with intellectual disabilities and challenging behavior. Hence, future research aimed at investigating the views of other healthcare professionals, such as registered nurses, is recommended to improve the competence provision within municipal health and social care services and thereby enhance the quality of care.

Adult neurodevelopmental services in Singapore: A sociodemographic and clinical profile at a tertiary psychiatric hospital

INTRODUCTION

The Adult Neurodevelopmental Service in Singapore is the first service of its kind in South-East Asia for adults with intellectual disability (ID) and/or autism spectrum disorder (ASD). However, few studies have documented and compared the sociodemographic characteristics and clinical needs of this subpopulation group.

METHODS

Initial assessments conducted from 1 January 2015 to 31 December 2016 were retrospectively reviewed for this descriptive study.

RESULTS

A total of 272 patients were included in the study (mean age 28.3 ± 11.5; 200 males, 72 females). Adults with ID comprised the largest percentage (52.9%), followed by those with ASD (30.2%), and then those with co-occurring ASD and ID (16.9%). The ASD subgroup had the highest proportion of individuals with employment, postsecondary school education, functional capabilities, and a psychiatric disorder. In comparison, adults with only ID and adults with co-occurring ASD and ID shared similar lower levels of education and employment, and had a higher proportion of individuals with epilepsy and aggressive behavior.

DISCUSSION

In this study, adults with ASD had a unique social profile with different clinical needs compared to adults with only ID or to adults with co-occurring ASD and ID. Adults with only ID and those with co-occurring ASD shared many of the same social characteristics and high clinical needs. The analysis of these profiles will be useful in developing services that better meet the needs of this complex group.

Communication difficulties in adults with Intellectual Disability: Results from a national cross-sectional study

BACKGROUND

People with an intellectual disability (ID) are vulnerable to communication impairments, with consequences for employment, education, and social participation.

AIMS

To identify the communication skills of a population of adults (40+ years) with ID and explore relationships between individual and environmental factors and communication skills.

METHODS AND PROCEDURES

Data from a sample of 601 adults with ID was selected from the Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing (IDS-TILDA) addressing communication characteristics, demographics, co-morbidities, challenging behaviours, and social participation. A multiple regression model and a decision-making tree were built to identify factors related to communication abilities.

OUTCOMES AND RESULTS

Overall, 57.9 % of participants experienced communication difficulties, with 23.5 % reporting severe difficulties. Only 75.1 % of participants communicated verbally; more than half found communicating with professionals and non-familiar partners difficult. Level of ID, low social participation, challenging behaviours, and diagnosis of Down syndrome were significantly associated with communication difficulties.

CONCLUSIONS AND IMPLICATIONS

Communication difficulties are prevalent in adults with ID and are influenced by complex factors. Interventions to enhance interaction and quality of life of individuals with ID should consider communication opportunities, needs, and barriers.

Training Direct-Care Staff to Provide Communication Intervention to Adults With Intellectual Disability: A Systematic Review

PURPOSE

The aim of this review was to summarize and evaluate studies on training direct-care staff to provide communication intervention to adults with intellectual disability.

METHOD

Systematic searches identified 22 studies. These were summarized and evaluated in terms of (a) participants; (b) settings; (c) training aims and procedures; (d) research designs; (e) reliability, integrity, and social validity; (f) outcomes; (g) generalization and follow-up; and (h) certainty of evidence.

RESULTS

A total of 437 staff and 254+ adults with intellectual disability participated. Staff training most frequently involved combinations of verbal instruction, role play, modeling, practice, and feedback. Reliability was assessed in 18 studies with acceptable standards for most of these studies. Treatment integrity and social validity were assessed in 1 and 3 studies, respectively, with positive outcomes. Generalization and maintenance were assessed in 5 and 8 studies, respectively, with predominantly positive outcomes. Most studies reported positive outcomes for staff and positive or mixed outcomes for the adults with intellectual disability. Certainty of evidence was rated as conclusive in 1 study, suggestive in 14 studies, and inconclusive in 7 studies.

CONCLUSIONS

There is sufficient evidence to conclude that direct-care staff can be taught to provide effective communication intervention to adults with intellectual disability. Professionals involved in providing training and support to direct-care staff could expect positive outcomes from multicomponent training programs that include opportunities for practice and feedback.

Meeting the communication support needs of children and young people with intellectual disabilities in the Bolivian Andes

Services available for people with disabilities in Bolivia tend to be fragmented and costly. Children and adults with intellectual disabilities are more likely to have a related communication disability and are thus both literally and metaphorically excluded from having a voice. The following research aimed to explore the experiences of accessing services by people with communication disabilities in Bolivia through semi-structured interviews and one focus group carried out with family members, professionals, service providers, educators and policymakers. It aimed to establish the nature of current services in Bolivia where knowledge, information and resources are scarce. Findings indicated the need to consider an alternative to a medical model approach through a focus on empowering other stakeholders to participate more fully in meeting communication support needs. Conclusions plot ideas for future service delivery and emphasize the central power of sharing practical and expert knowledge.

Paralinguistic abilities of adults with intellectual disability

The aim of this research was to determine the ability level of paralinguistic production and comprehension in adults with intellectual disability (ID) with regard to the level of their intellectual functioning and presence of co-morbid psychiatric conditions or dual diagnosis (DD). The sample consisted of 120 participants of both genders, ranging in age between 20 and 56 years (M=31.82, SD=8.702). Approximately 50% of the sample comprised participants with a co-existing psychiatric condition. Each of these two sub-samples (those with ID only and those with DD) consisted of 25 participants with mild ID and 35 participants with moderate ID. The paralinguistic scale from The Assessment Battery for Communication (ABaCo; Sacco et al., 2008) was used to assess the abilities of comprehension and production of paralinguistic elements. The results showed that the participants with mild ID are more successful than the participants with moderate ID both in paralinguistic comprehension tasks (p=.000) and in paralinguistic production tasks (p=.001). Additionally, the results indicated the presence of separate influences of both ID levels on all of the paralinguistic abilities (F [116]=42.549, p=.000) and the existence of DD (F [116]=18.215, p=.000).

An investigation of self-injurious behaviors in adults with severe intellectual disabilities

Self-injurious behavior (SIB) is commonly observed among individuals with intellectual disability (ID) living in state-run supports and services centers. Specific examples of SIB include poking oneself in the eye; harming oneself by hitting, scratching, or pinching; and pica (i.e., swallowing objects causing bodily harm). Previous research has focused on SIB in individuals with ID more generally without focusing on specific levels of ID or taking into account other important personal variables. This study examined 45 adults with severe ID living in two large state-run facilities in the Southeastern United States who were separated into groups for comparison (ASD and non ASD; verbal and nonverbal). Data was collected on the presence of SIB using the Autism Spectrum Disorder-Problem Behavior Adult Version (ASD-PBA). A two-way analysis of variance (ANOVA) was conducted to determine if there were significant differences between groups on rates of SIB. Individuals with ID and ASD exhibited significantly higher rates of SIB than individuals with only ID, F (1,43)=50.84, p<0.05. Furthermore, verbal individuals had significantly higher rates of SIB than nonverbal individuals, F (1,43)=57.612, p<0.05. There was a significant interaction between the effects of ASD diagnosis and verbal ability on rates of SIB, F (1,43)=50.84, p<0.05. The implications of these findings in the context of other research on ID, ASD, SIB, and verbal abilities are discussed.

An examination of specific daily living skills deficits in adults with profound intellectual disabilities

While some researchers have investigated daily living skills deficits in individuals with intellectual disability (ID) as a whole, research on specific daily living skills in a profound ID population is limited. Two hundred and four adults with profound ID residing in two large developmental centers in the southeast portion of the United States were studied. Data were collected on these individuals' daily living skills, utilizing the Vineland Adaptive Behavior Scales (VABS). Three dependent t-tests were conducted comparing the proportion of items endorsed by informants on each of the three subdomains of daily living skills on the VABS (personal, domestic, and community). A significantly larger proportion of Personal Subdomain items were endorsed compared to Domestic or Community Subdomain items. Additionally, participants exhibited a significantly larger proportion of Domestic Skills Subdomain items compared to Community Skills Subdomain items which is consistent with theoretical models suggesting that institutional living may curb broader community skill sets. No gender differences were found in daily living skills. Lastly, individuals between the ages 30 and 39 exhibited significantly more Personal Subdomain skills than individuals who were 60 or older, while participants between the ages 30 and 39 exhibited significantly more Domestic Subdomain skills than individuals between the ages 60 and 69.
