Developing a Health-Related Quality-of-Life Measure for People With Intellectual Disability

A scoping review of the use of visual tools and adapted easy-read approaches in Quality-of-Life instruments for adults

PURPOSE

Self-Reporting using traditional text-based Quality-of-Life (QoL) instruments can be difficult for people living with sensory impairments, communication challenges or changes to their cognitive capacity. Adapted communication techniques, such as Easy-Read techniques, or use of pictures could remove barriers to participation for a wide range of people. This review aimed to identify published studies reporting adapted communication approaches for measuring QoL, the methodology used in their development and validation among adult populations.

METHODS

A scoping review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews checklist was undertaken.

RESULTS

The initial search strategy identified 13,275 articles for screening, with 264 articles identified for full text review. Of these 243 articles were excluded resulting in 21 studies for inclusion. The majority focused on the development of an instrument (12 studies) or a combination of development with some aspect of validation or psychometric testing (7 studies). Nineteen different instruments were identified by the review, thirteen were developed from previously developed generic or condition-specific quality of life instruments, predominantly aphasia (7 studies) and disability (4 studies). Most modified instruments included adaptations to both the original questions, as well as the response categories.

CONCLUSIONS

Studies identified in this scoping review demonstrate that several methods have been successfully applied e.g. with people living with aphasia post-stroke and people living with a disability, which potentially could be adapted for application with more diverse populations. A cohesive and interdisciplinary approach to the development and validation of communication accessible versions of QOL instruments, is needed to support widespread application, thereby reducing reliance on proxy assessors and promoting self-assessment of QOL across multiple consumer groups and sectors.

Development and content validity of the Person Experiences Interview Survey (PEIS): a measure of the mental health services experiences of people with developmental disabilities

Purpose

People with developmental disabilities and mental health service experiences have a right to be included in healthcare decisions, including the evaluation of their mental health services and providers. However, few self-report measures address this need. This study aimed to fill this gap by developing and evaluating the content validity, including comprehension, relevance, and comprehensiveness, of the Person Experiences Interview Survey (PEIS) with people with developmental disabilities and mental health experiences.

Methods

The research team established a measurement framework based on the Family Experiences Interview Survey (FEIS), resulting in 21 PEIS items that were written in collaboration with young adults with developmental disabilities and mental health service experiences. Comprehension, relevance, and comprehensiveness were evaluated through cognitive interviews with people with developmental disabilities and mental health service experiences (respondents; n = 9) ages 23-49 years. Comprehensiveness and relevance were also evaluated in focus groups with family caregivers (n = 9) and mental health providers (n = 10) who serve this population. Two researchers independently coded open-ended responses to the PEIS for comprehension. A content validity index (CVI), indicating relevance, was calculated for each participant group for each item, and comprehensiveness was rated for item sets.

Results

Fifteen of the 21 items met the criteria of ≥80% comprehension, with 89-100% of responses containing all or some intended information. All items met the CVI ≥80% criterion in at least two of the three groups. In all item sets, between 1 and 4 family members or providers felt one question was missing. Respondents used the response scale in a manner that corresponded with their open-ended descriptions, and family caregivers and providers had positive feedback about the response scale's visual cues and number of choices. Using these findings, four items were removed and six items were revised, resulting in a 17-item measure.

Conclusion

This study presents a novel and promising measure, the Person Experiences Interview Survey (PEIS). It also demonstrates that the employment of accessible methods allows people with developmental disabilities to meaningfully evaluate mental health services and providers. The PEIS shows great promise for application in the field by engaging those directly involved in the evaluation of mental health services and providers.

The experiences of students with intellectual and developmental disabilities, parents, and teachers regarding health self-advocacy program with school-home connection: a qualitative study

Background

Despite the importance of health as a significant indicator of quality of life, individuals with intellectual and developmental disabilities (IDD) often face low expectations, stigma, and insufficient opportunities in health care and education. In response, we developed a health self-advocacy program with a school-home connection for students with IDD to promote self-directed health care and verified its effectiveness by implementing the program for students with IDD.

Objective

This study aimed to explore participants' program experiences and support needs to reduce the stigma surrounding individuals with IDD and provide implications for enhancing health self-advocacy skills.

Methods

Individual and focus group interviews were conducted with 14 students, six parents, and four teachers who participated in the program. The collected data were analyzed using the constant comparative method.

Results

The following five main themes emerged: (a) the gap between perception and practice in health care; (b) advantages and influencing factors of the program; (c) challenges in program implementation; (d) outcomes of program implementation; and (e) support needs for promoting health self-advocacy.

Conclusion

Based on these findings, implications are provided and discussed to reduce the stigma surrounding individuals with IDD and enhance health self-advocacy.

Lessons Learned From Research Collaboration Among People With and Without Developmental Disabilities

Research related to the developmental disability (DD) community should include collaboration with individuals with DD. Unfortunately, people with DD are infrequently involved in research projects in meaningful ways, and there is little guidance about how to collaborate equitably with researchers with DD. The purpose of this article is to share lessons learned from a collaborative research study among researchers with and without DD using both qualitative and quantitative methods to develop and examine the effectiveness of a civic engagement intervention for transition-aged youth with disabilities. It includes how our research team compensated researchers with DD, clarified team member roles, leveraged the expertise of researchers with DD in using both qualitative and quantitative methods, and integrated technology throughout the research process.

Facilitating the inclusion of adults with intellectual disability as direct respondents in research: Strategies for fostering trust, respect, accessibility and engagement

BACKGROUND

Adults with intellectual disability experience disparities in social determinants of health and health outcomes. While new knowledge can advance health equity, adults with intellectual disability are frequently excluded from being direct respondents in research. Their inclusion requires addressing scientific and ethical challenges that contribute to their exclusion.

METHOD

We describe our multi-phased process, inclusive of community-engagement, to develop a self-report survey for adults with intellectual disability and share findings from an institutional ethnography conducted to identify strategies for facilitating inclusion. We also assessed indicators of the quality of these strategies.

RESULTS

We identified building trust, showing respect, designing in accessibility, maximising flexibility and allowing individualised accommodations as strategies that foster inclusion. Multiple indicators validate the effectiveness of these strategies.

CONCLUSIONS

Researchers can promote first-person decision-making and direct research participation by focusing on promoting accessibility, trust, respect and engagement.

Improved Motor Proficiency and Quality of Life in Youth With Prader-Willi Syndrome and Obesity 6 Months After Completing a Parent-Led, Game-Based Intervention

PURPOSE

To determine changes and potential differences in physical activity (PA), gross motor proficiency (MP), and health parameters after a 6-month follow-up (FU) period following participation in a parent-led PA intervention in youth with or without Prader-Willi syndrome (PWS).

METHODS

About 42 youth with PWS and 65 youth without PWS but with obesity (body fat percentage >95th percentile for age and sex), aged 8-16 years, participated. The intervention included preplanned PA sessions containing playground and console-based video games scheduled 4 days per week for 24 weeks. Families received training and curriculum materials. PA (accelerometry), MP (Bruininks-Oseretsky Test of MP), and health-related quality of life were obtained before (PRE), after completing the intervention (POST), and at FU.

RESULTS

There were no significant changes in PA at any time point. At FU and POST, participants showed higher bilateral coordination (PRE = 9.3 [0.4], POST = 11.7 [0.5], and FU = 11.1 [0.6]); speed and agility (PRE = 9.2 [0.4], POST = 10.8 [0.4], and FU = 11.5 [0.5]); and strength (PRE = 8.0 [0.3], POST = 9.2 [0.3], and FU = 9.2 [0.3]) than at PRE. At FU (80.3 [2.1]) and POST (79.8 [1.7]), youth without PWS showed higher health-related quality of life than PRE (75.0 [1.8]).

CONCLUSION

The improvements in MP and health-related quality of life at FU suggest long-term durability of intervention outcomes.

What activities individuals with intellectual disabilities do for fun: exploration into self-care

Participation in enjoyable activities is instrumental to improving individuals' quality of life. Previous studies have indicated engagement in community-based activities and physical exercise are beneficial to individuals with intellectual disabilities (ID). The purpose of this study was to understand, from their perceptions, fun activities in which individuals with ID engaged. One hundred and sixty-nine participants with ID provided 561 responses, which described what they do for fun. A multidisciplinary research team utilized a Consensual Qualitative Research (CQR) approach to differentiate responses into a list of categories that fit into six central domains. Domains (with frequency of responses) included: Community and Relationship Building Activities (130), Sports and Other Physical Activities (123), Technology and Gaming (105), Music and Other Preforming Arts (69), Mentally-Stimulating Activities (51), and Categories Outside of a Domain (82). These findings indicate that individuals with ID have a variety of interests. Our discussion, which reviews literature on individuals with and without ID, suggests similar leisure activity engagement among both groups. This literature also suggests individuals with ID experience similar benefits to their peers without ID when engaging in leisure activities. Our results provide a framework to explore self-care routines that can improve quality of life for individuals with ID.

Psychometric properties of a brief self-reported health-related quality of life measure (HRQoL-IDD) for persons with intellectual and developmental disabilities

Background

To encourage self‐determination and address health disparities among persons with intellectual and developmental disabilities, clinicians and researchers rely on self‐reported measures like health‐related quality of life (HRQoL). This study evaluated the psychometric properties of a theory‐driven self‐reported HRQoL measure for adults requiring mild to moderate support related to intellectual and developmental disabilities.

Method

224 volunteers completed 42 quality of life items developed with extensive input from persons with intellectual and developmental disabilities, family members/caregivers, and providers. The 5‐point Likert scale format with visual images of fluid‐filled cups represented the range of responses.

Results

Exploratory and Unrestricted Factor Analyses yielded 16 HRQoL items with 4 subscales: Functional Well‐Being, Emotional Well‐Being, Social Well‐Being, and Healthy Decision‐making. The HRQoL‐IDD explained 62.8% of variance, had satisfactory internal consistency (0.73–0.83), stability of reponses, and reading level (2nd grade, ages 7‐8).

Conclusions

The HRQoL‐IDD is a promising measure of self‐reported HRQoL for use in community‐based settings for persons requiring mild to moderate support related to intellectual and developmental disabilities.
