The impact of visual impairment on the ability to perform activities of daily living for persons with severe/profound intellectual disability

A Technology Aid to Help People with Blindness and Moderate Intellectual Disability Retrieve Common Objects from Storage Units: A Proof-of-Concept Study

BACKGROUND

People with blindness and intellectual disability can have problems locating, identifying, and retrieving objects needed for daily activities (e.g., clothes and food items) from familiar storage contexts, such as cupboards and cabinets.

OBJECTIVE

This preliminary study assessed a technological system designed to help three people with those problems improve their performance.

METHODS

The technological system, which involved the use of tags with radio frequency identification codes, a smartphone, and a tag reader, aimed to guide the participants in searching and retrieving objects from three different storage units. In practice, the system provided different feedbacks depending on whether the participants were searching (a) in a wrong storage unit, (b) in a wrong shelf/drawer of the right storage unit, or (c) in the right shelf/drawer of the right storage unit.

RESULTS

All participants were successful in retrieving objects correctly with the technological system. The results also showed that (a) the participants preferred using the system over a control strategy, (b) were able to switch on and off the system independently, and (b) staff rated the system positively.

CONCLUSIONS

These preliminary findings suggest that the system might be a useful support tool for people with blindness and intellectual disability.

Enabling People With Intellectual and Sensory Disabilities to Trigger a Tablet's Delivery of Task Instructions by Walking to the Tablet: Proof-of-Concept Study

BACKGROUND

People with intellectual and sensory or sensory-motor disabilities tend to have problems performing multistep tasks. To alleviate their problems, technological solutions have been developed that provide task-step instructions. Instructions are generally delivered at people's request (eg, as they touch an area of a computer or tablet screen) or automatically, at preset intervals.

OBJECTIVE

This study carried out a preliminary assessment of a new tablet-based technology system that presented task-step instructions when participants with intellectual and sensory disabilities walked close to the tablet (ie, did not require participants to perform fine motor responses on the tablet screen).

METHODS

The system entailed a tablet and a wireless camera and was programmed to present instructions when participants approached the tablet, that is, when the camera positioned in front of the tablet detected them. Two instructions were available for each task step. One instruction concerned the object(s) that the participants were to collect, and the other instruction concerned the "where" and "how" the object(s) collected would need to be used. For 3 of the six participants, the two instructions were presented in succession, with the second instruction presented once the required object(s) had been collected. For the other 3 participants, the two instructions were presented simultaneously. Instructions consisted of pictorial representations combined with brief verbal phrases. The impact of the system was assessed for each of the 2 groups of participants using a nonconcurrent multiple baseline design across individuals.

RESULTS

All participants were successful in using the system. Their mean frequency of correct task steps was close to or above 11.5 for tasks including 12 steps. Their level of correct performance tended to be much lower during the baseline phase when they were to receive the task-step instructions from a regular tablet through scrolling responses.

CONCLUSIONS

The findings, which need to be interpreted with caution given the preliminary nature of the study, suggest that the new tablet-based technology system might be useful for helping people with intellectual and sensory disabilities perform multistep tasks.

Loneliness and Coping Styles Among Athletes With Disabilities During the COVID-19 Pandemic

The study aimed to assess loneliness experiences among athletes with disabilities (AWD) during the different phases of the pandemic and to understand its relationship with coping styles. Ninety-one AWD participated in a longitudinal study spanning 10 months, covering three time points: April (A), June (Time B), and November (Time C) 2021. The study used the Coping Inventory for Stressful Situations and the revised University of California Los Angeles Loneliness Scale-Revised (UCLA-R) to measure coping mechanisms and feelings of loneliness, respectively. Loneliness levels peaked during the most intense phase of the pandemic, showing significant differences between consecutive time points (χ2 = 20.29, p < 0.001, d = 0.24). The most robust regression models were built in Time B, using the "intimate contacts" dimension of loneliness as the dependent variable and "emotion-oriented coping", "avoidance-oriented coping", and "impairment" as independent variables, explaining 44% of the variance (p < 0.001). Loneliness among Paralympic athletes fluctuated during various phases of the pandemic. The findings highlight the significant influence of coping styles, particularly emotional styles which heightened perceived loneliness, and task-oriented styles which reduced it, on athletes' experiences of loneliness. These results underscore the need for longitudinal studies to delve deeper into the relationship between loneliness and mental health. Moreover, they stress the importance of developing tailored interventions that promote effective coping mechanisms in AWD during challenging times amid to COIVID-19.

From assistive to inclusive? A systematic review of the uses and effects of technology to support people with pervasive support needs

BACKGROUND

Although particular technologies can enhance the quality of life (QoL) of people with profound intellectual and multiple disabilities (we use the term pervasive support needs), their objectives and outcomes are understudied. A systematic literature review was therefore conducted to explore this topic.

METHOD

A search of four databases yielded 64 studies. Data were extracted on their general characteristics, methods and sample characteristics as well as the technology types, QoL domains and application within ecological systems. A narrative synthesis was subsequently developed.

RESULTS

Most of the studies applied assistive technology (AT) and focused on personal development and self-determination on an individual level.

CONCLUSIONS

Technology can enhance the QoL of people with pervasive support needs. There are indications that although MT and UD-based technology are used in practice, few studies have examined these technologies. Therefore, there is a knowledge gap regarding the kinds of technology that are used in practice.

Enabling people with intellectual and other disabilities to make verbal requests using cardboard chips with mini objects or pictures and a smartphone

Objective

This study aimed to help six participants with intellectual disability combined with sensory and motor impairments to make verbal requests through the use of a technology system involving cardboard chips and a smartphone.

Method

The participants were divided into two groups of three based on whether they did or did not have visual skills. Each group was exposed to the intervention with the technology system according to a non-concurrent multiple baseline across participants design. During the 20 min intervention sessions, the participants were provided with a smartphone and nine cardboard chips each of which had a picture or object (i.e., a mini object replica or raised object contour) and several radio frequency identification tags attached to it. To make a request, the participants were to bring a cardboard chip in contact with the smartphone. This read the tags attached to the cardboard and verbalized the request related to that cardboard.

Results

During the baseline (without cardboard chips and smartphone), the participants' mean frequency of independent requests (all non-verbal requests) varied between zero and near 1.5 per session. During the intervention (with cardboard chips and smartphone), the participants' mean frequency of independent requests (all verbal requests) varied between over 4.5 and about 10 per session.

Conclusion

The results suggest that the system might be useful to help participants like the ones included in this study to make verbal requests with simple responses.

Low-Cost Technology-Aided Programs for Supporting People With Motor, Visual, and Intellectual Disabilities in Functional Forms of Occupation and Communication: Proof-of-Concept Study

BACKGROUND

People with motor, visual, and intellectual disabilities may have serious problems in independently accessing various forms of functional daily occupation and communication.

OBJECTIVE

The study was aimed at developing and assessing new, low-cost technology-aided programs to help people with motor or visual-motor and intellectual disabilities independently engage in functional forms of occupation and communication with distant partners.

METHODS

Two programs were set up using a smartphone interfaced with a 2-switch device and a tablet interfaced with 2 pressure sensors, respectively. Single-subject research designs were used to assess (1) the first program with 2 participants who were blind, had moderate hand control, and were interested in communicating with distant partners through voice messages; and (2) the second program with 2 participants who possessed functional vision, had no or poor hand control, and were interested in communicating with their partners through video calls. Both programs also supported 2 forms of occupational engagement, that is, choosing and accessing preferred leisure events consisting of songs and music videos, and listening to brief stories about relevant daily topics and answering questions related to those stories.

RESULTS

During the baseline phase (when only a conventional smartphone or tablet was available), 2 participants managed sporadic access to leisure or leisure and communication events. The other 2 participants did not show any independent leisure or communication engagement. During the intervention (when the technology-aided programs were used), all participants managed to independently engage in multiple leisure and communication events throughout the sessions and to listen to stories and answer story-related questions.

CONCLUSIONS

The findings, which need to be interpreted with caution given the nature of the study and the small number of participants, seem to suggest that the new programs may be viable tools for helping people with motor or visual-motor and intellectual disabilities independently access leisure, communication, and other forms of functional engagement.

Technology-Aided Spatial Cues, Instructions, and Preferred Stimulation for Supporting People With Intellectual and Visual Disabilities in Their Occupational Engagement and Mobility: Usability Study

Background

Persons with severe or profound intellectual disability and visual impairment tend to be passive and sedentary, and technology-aided intervention may be required to improve their condition without excessive demands on staff time.

Objective

This study aims to extend the assessment of technology-aided interventions for supporting functional occupational engagement and mobility in 7 people with intellectual disability and visual impairment and to use a technology system that is simpler and less expensive than those previously used.

Methods

The technology system involved a Samsung Galaxy A10, 4 Philips Hue indoor motion sensors, and 4 mini speakers. Within each session, the participants were to collect 18 objects (ie, one at a time) from 3 different areas (stations) located within a large room, bring each of the objects to a central desk, and put away each of those objects there. For each object, the participants received verbal (spatial) cues for guiding them to the area where the object was to be collected, a verbal instruction (ie, request) to take an object, verbal (spatial) cues for guiding them to the central desk, a verbal instruction to put away the object collected, and praise and preferred stimulation.

Results

During baseline, the frequency of responses completed correctly (objects collected and put away independently) was 0 or near 0. During the intervention phase (ie, with the support of the technology setup), the frequency increased for all participants, reaching a mean of almost 18 (out of 18 response opportunities) for 6 participants and about 13 for the remaining participant. The mean session duration ranged from 12 to 30 minutes.

Conclusions

A program, such as the one used in this study, can be useful in promoting occupational engagement and mobility in persons with intellectual disability and visual impairment.

Latinx Parents' Perceptions of Neighborhood Walking Safety for Their Youth With Intellectual Disabilities: A Mixed-Methods Investigation

Increased walking distance and frequency has been linked to positive health outcomes. Neighborhood walkability disproportionately impacts youth with intellectual and developmental disabilities (IDD). We investigated concerns of Latinx parents of youth with IDD about walkability and their impact on families' walking behavior. We surveyed Latinx parents of youth with IDD (n = 21) and compared results with the general population. Results were triangulated with a focus group (n = 5). Survey data were analyzed using a Mann-Whitney U test, and focus group data via thematic analysis. We found a significant difference (P < .05) between parents of youth with IDD and the general population on perceived aesthetics, opportunity to participate, and satisfaction. Latinx parents and their youth with IDD experience disparities in the safety and pleasantness of their communities for walking, which may contribute to decreased community participation, poorer health outcomes, and lower levels of neighborhood satisfaction among this already vulnerable population.

Intervention effects on professionals' attitudes towards the participation of adults with visual and severe or profound intellectual disabilities

Background

We investigated the effects of the “Care for Participation+” (CFP+) intervention on direct support professionals’ (DSPs’) attitudes regarding the participation of adults with visual and severe or profound intellectual disabilities (VSPID).

Methods

We implemented a pilot non‐randomized controlled trial with two control groups to compare DSPs’ attitudes towards CFP+ using the Attitudes towards Participation Questionnaire (APQ) and DSPs’ written profiles of adults with VSPID.

Results

CPP+ and the Participation Mind Map control group showed a positive trend for the “leisure/recreation,” “social relations,” and “ability to act” APQ domains compared to the usual care control group. The CFP+ group described significantly fewer disabilities at 6 months, reflecting a more positive attitude than controls.

Conclusion

CFP+ had positive effects on DSPs’ attitudes towards the participation of adults with VSPID. The small sample size, ceiling effects, measurement instruments used, and implementation difficulties may have hampered understanding the full potential of CFP+.

Improving the participation of adults with visual and severe or profound intellectual disabilities: a process evaluation of a new intervention

BACKGROUND

While the participation of adults with visual and severe or profound intellectual disabilities (VSPID) in society and community life is important, evidence-based interventions to improve their participation are lacking. We conducted a process evaluation of the implementation of 'Care for Participation+' (CFP+), a new intervention targeting the attitudes of direct support professionals (DSPs) toward the participation of adults with VSPID, within a residential facility in the Netherlands.

METHODS

CFP+ was inspired by the Boston Psychiatric Rehabilitation Approach and adapted by adopting a new definition and operationalization of the concept of participation for adults with VSPID. Following systematic training, 16 DSPs of adults with VSPID were able to apply key elements of CFP+ to explore diverse roles and activities for this population, facilitating their self-management, teaching them necessary skills for participation, and organizing support. Our process evaluation entailed an investigation of the delivered dose, reach, fidelity, and adaptation of CFP+ during and after the CFP+ intervention. We also evaluated the mechanisms of impact and context using questionnaires, assignments, documentation, interviews, and a logbook.

RESULTS

The intended dose, reach, and fidelity relating to the implementation of CFP+ were not achieved. Despite this fact, an assessment of the mechanisms of impact indicated that assignments of CFP+ were well (75%) or reasonably well (17%) understood by DSPs. CFP+ was applied by DSPs to stimulate self-management (83% of DSPs), new activities (100%), enhanced involvement in existing activities (67%) and to explore new roles (50%) for adults with VSPID. A negative contextual factor mentioned by the trainer and manager was the DSPs' lack of commitment to the training program. Another negative contextual factor mentioned by DSPs was the lack of time for implementing CFP+.

CONCLUSIONS

CFP+ provides new opportunities to improve the participation of adults with VSPID. Despite the non-optimal conditions for implementing CFP+ and the DSPs' general reluctance to apply the new intervention, some have actively used CFP+ within the residential facility. Future studies should focus on the outcomes of CFP+ regarding attitudinal changes among DSPs relating to the participation of adults with VSPID and their quality of life.

Progressive resistance training for persons with intellectual disabilities and visual impairment

BACKGROUND

Knowledge concerning the feasibility and effects of progressive resistance training (PRT) for persons with intellectual disabilities and visual impairment who are categorized in Gross Motor Function Classification System (GMFCS) Level 1 is limited. The aim of our study was to evaluate feasibility and effect of PRT on participants' Quadriceps strength and personal goals.

METHODS

Eight Participants followed a PRT program for 10 weeks. Feasibility was determined by percentage of attendance and compliance. The effect of PRT was analyzed with a linear mixed model (p < 0.05) and by normalized bootstrap (95% CI).

RESULTS

Participants attended 87.8% of the sessions and trained according to the PRT program, indicating sufficient compliance. Quadriceps strength increased significantly by 69%, and participants' personal goals were achieved.

CONCLUSION

PRT is a feasible and potentially effective method for increasing Quadriceps strength as well as achieving personal goals in persons with intellectual disabilities and visual impairment with GMFCS Level 1.

Adaptive behaviour and quality of life in school-age children with congenital visual disorders and different levels of visual impairment

BACKGROUND

Adaptive behaviours are vital skills that allow individuals to function independently and are potentially amenable to behavioural interventions. Previous research indicated that adaptive behaviours are reduced in children and adolescents with severe to profound VI, but it was unclear if this was also the case for children with mild to moderate VI.

AIM

The aim of the study was to assess differences in adaptive behaviour in children with congenital visual disorders and different levels of visual impairment and their influence on quality of life and everyday strengths and difficulties.

METHODS AND PROCEDURES

Questionnaires about adaptive behaviour, strengths and difficulties, and quality of life were completed by parents of school-age children with severe-to-profound VI (S/PVI, n = 9, 0.9 logMAR - light perception only), mild-to-moderate VI (MVI, n = 9, 0.1-0.7 logMAR), or typical sight (control, n = 18, -0.3 to 0.1 logMAR). Differences in questionnaire domains by the severity of VI and relationships between adaptive behaviour and quality of life were analysed in general linear models.

OUTCOMES AND RESULTS

The questionnaire ratings indicated reduced adaptive behaviour, more difficulties, and reduced quality of life in children with S/PVI compared to typically-sighted peers. Effects were smaller for children with MVI, but indicated a significant reduction in quality of life compared to typically-sighted children. The effect of visual impairment on quality of life in school was partially mediated by adaptive behaviour.

CONCLUSION AND IMPLICATION

Severe congenital visual impairment affects adaptive behaviour in children with verbal abilities in the typical range. This effect is less pronounced in children with mild-to-moderate VI, but still impacts on quality of life, particularly in school.

Should the Gross Motor Function Classification System be used for children who do not have cerebral palsy?

This literature review addressed four questions. (1) In which populations other than cerebral palsy (CP) has the Gross Motor Function Classification System (GMFCS) been applied? (2) In what types of study, and why was it used? (3) How was it modified to facilitate these applications? (4) What justifications and evidence of psychometric adequacy were used to support its application? A search of PubMed, MEDLINE, and Embase databases (January 1997 to April 2017) using the terms: 'GMFCS' OR 'Gross Motor Function Classification System' yielded 2499 articles. 118 met inclusion criteria and reported children/adults with 133 health conditions/clinical descriptions other than CP. Three broad GMFCS applications were observed: as a categorization tool, independent variable, or outcome measure. While the GMFCS is widely used for children with health conditions/clinical description other than CP, researchers rarely provided adequate justification for these uses. We offer recommendations for development/validation of other condition-specific classification systems and discuss the potential need for a generic gross motor function classification system.

WHAT THIS PAPER ADDS

The Gross Motor Function Classification System should not be used outside cerebral palsy or as an outcome measure. The authors provide recommendations for development and validation of condition-specific or generic classification systems.
