Creating Accessible Survey Instruments for Use with Autistic Adults and People with Intellectual Disability: Lessons Learned and Recommendations

Despite growing appreciation of the need for research on autism in adulthood, few survey instruments have been validated for use with autistic adults. We conducted an institutional ethnography of two related partnerships that used participatory approaches to conduct research in collaboration with autistic people and people with intellectual disability. In this article, we focus on lessons learned from adapting survey instruments for use in six separate studies. Community partners identified several common problems that made original instruments inaccessible. Examples included: (1) the use of difficult vocabulary, confusing terms, or figures of speech; (2) complex sentence structure, confusing grammar, or incomplete phrases; (3) imprecise response options; (4) variation in item response based on different contexts; (5) anxiety related to not being able to answer with full accuracy; (6) lack of items to fully capture the autism-specific aspects of a construct; and (7) ableist language or concepts. Common adaptations included: (1) adding prefaces to increase precision or explain context; (2) modifying items to simplify sentence structure; (3) substituting difficult vocabulary words, confusing terms, or figures of speech with more straightforward terms; (4) adding hotlinks that define problematic terms or offer examples or clarifications; (5) adding graphics to increase clarity of response options; and (6) adding new items related to autism-specific aspects of the construct. We caution against using instruments developed for other populations unless instruments are carefully tested with autistic adults, and we describe one possible approach to ensure that instruments are accessible to a wide range of autistic participants.

LAY SUMMARY

Why is this topic important?: To understand what can improve the lives of autistic adults, researchers need to collect survey data directly from autistic adults. However, most survey instruments were made for the general population and may or may not work well for autistic adults.What is the purpose of this article?: To use lessons learned from our experience adapting surveys-in partnership with autistic adults-to create a set of recommendations for how researchers may adapt instruments to be accessible to autistic adults.What did the authors do?: Between 2006 and 2019, the Academic Autism Spectrum Partnership in Research and Education (AASPIRE) and the Partnering with People with Developmental Disabilities to Address Violence Consortium used a participatory research approach to adapt many survey instruments for use in six separate studies. We reviewed records from these partnerships and identified important lessons.What is this recommended adaptation process like?: The adaptation process includes the following:  (1) Co-creating collaboration guidelines and providing community partners with necessary background about terminology and processes used in survey research; (2) Collaboratively selecting which constructs to measure; (3) Discussing each construct so that we can have a shared understanding of what it means; (4) Identifying existing instruments for each construct; (5) Selecting among available instruments (or deciding that none are acceptable and that we need to create a new measure); (6) Assessing the necessary adaptations for each instrument; (7) Collaboratively modifying prefaces, items, or response options, as needed; (8) Adding "hotlink" definitions where necessary to clarify or provide examples of terms and constructs; (9) Creating new measures, when needed, in partnership with autistic adults;(10)Considering the appropriateness of creating proxy report versions of each adapted measure; and(11)Assessing the adapted instruments' psychometric properties.What were common concerns about existing instruments?: Partners often said that, if taking a survey that used the original instruments, they would experience confusion, frustration, anxiety, or anger. They repeatedly stated that, faced with such measures, they would offer unreliable answers, leave items blank, or just stop participating in the study. Common concerns included the use of difficult vocabulary, confusing terms, complex sentence structure, convoluted phrasings, figures of speech, or imprecise language. Partners struggled with response options that used vague terms. They also felt anxious if their answer might not be completely accurate or if their responses could vary in different situations. Often the surveys did not completely capture the intended idea. Sometimes, instruments used offensive language or ideas. And in some cases, there just were not any instruments to measure what they thought was important.What were common adaptations?: Common adaptations included: (1) adding prefaces to increase precision or explain context; (2) modifying items to simplify sentence structure; (3) substituting difficult vocabulary words, confusing terms, or figures of speech with more straightforward terms; (4) adding hotlinks that define problematic terms or offer examples or clarifications; (5) adding graphics to increase clarity of response options; and (6) adding new items related to autism-specific aspects of the construct.How will this article help autistic adults now or in the future?: We hope that this article encourages researchers to collaborate with autistic adults to create better survey instruments. That way, when researchers evaluate interventions and services, they can have the right tools to see if they are effective.

Adults with Developmental Disabilities: A Comprehensive Approach to Medical Care

Developmental disabilities are attributable to a cognitive impairment, physical impairment, or both. They manifest during the developmental period from birth to early adulthood, and are likely to continue indefinitely. The life expectancy of most persons with developmental disabilities now approaches that of the general population. According to the neurodiversity model of care, developmental disability is accepted as a valued part of human neurologic diversity. The social model focuses on improving participation in society with accommodations such as adaptive equipment or improvements to the social and physical environment. The goal of health care for patients with developmental disabilities is to improve their well-being, function, and participation in family and community. Physicians should communicate directly with their patients, even those who have communication or cognitive differences. Communication may include speech, sign language, writing, letter boards, voice output devices, pictures, facial expressions, gestures, vocalizations, and behavior. Supported decision making is a paradigm, support practice, and emerging legal structure that focuses on assisting patients with communicating their wants and needs as an alternative to guardianship or power of attorney. When establishing care, it is critical to get a detailed history of baseline traits and characteristics in the areas of cognition and communication; neuromuscular function; sensory function such as vision, hearing, and sensory processing; seizure threshold; mental health; and behavior. In general, guidelines for age-appropriate health maintenance in the general population should be followed unless the risk outweighs the benefit for an individual patient. With accurate diagnosis, psychiatric conditions can be treated effectively with the same medical, behavioral, and therapeutic modalities used in the general population. Just like any patient, those with developmental disabilities should have access to a full range of life-sustaining, curative, and end-of-life services.

Barriers to healthcare: Instrument development and comparison between autistic adults and adults with and without other disabilities

Our objective was to use a community-based participatory research approach to identify and compare barriers to healthcare experienced by autistic adults and adults with and without other disabilities. To do so, we developed a Long- and Short-Form instrument to assess barriers in clinical and research settings. Using the Barriers to Healthcare Checklist-Long Form, we surveyed 437 participants (209 autistic, 55 non-autistic with disabilities, and 173 non-autistic without disabilities). Autistic participants selected different and greater barriers to healthcare, particularly in areas related to emotional regulation, patient-provider communication, sensory sensitivity, and healthcare navigation. Top barriers were fear or anxiety (35% (n = 74)), not being able to process information fast enough to participate in real-time discussions about healthcare (32% (n = 67)), concern about cost (30% (n = 62)), facilities causing sensory issues 30% ((n = 62)), and difficulty communicating with providers (29% (n = 61)). The Long Form instrument exhibited good content and construct validity. The items combined to create the Short Form had predominantly high levels of correlation (range 0.2-0.8, p < 0.001) and showed responsiveness to change. We recommend healthcare providers, clinics, and others working in healthcare settings to be aware of these barriers, and urge more intervention research to explore means for removing them.

The health status of adults on the autism spectrum

Compared to the general pediatric population, children with autism have higher rates of co-occurring medical and psychiatric illnesses, yet very little is known about the general health status of adults with autism. The objective of this study was to describe the frequency of psychiatric and medical conditions among a large, diverse, insured population of adults with autism in the United States. Participants were adult members of Kaiser Permanente Northern California enrolled from 2008 to 2012. Autism spectrum disorder cases ( N = 1507) were adults with autism spectrum disorder diagnoses (International Classification of Diseases-9-Clinical Modification codes 299.0, 299.8, 299.9) recorded in medical records on at least two separate occasions. Controls ( N = 15,070) were adults without any autism spectrum disorder diagnoses sampled at a 10:1 ratio and frequency matched to cases on sex and age. Adults with autism had significantly increased rates of all major psychiatric disorders including depression, anxiety, bipolar disorder, obsessive–compulsive disorder, schizophrenia, and suicide attempts. Nearly all medical conditions were significantly more common in adults with autism, including immune conditions, gastrointestinal and sleep disorders, seizure, obesity, dyslipidemia, hypertension, and diabetes. Rarer conditions, such as stroke and Parkinson’s disease, were also significantly more common among adults with autism. Future research is needed to understand the social, healthcare access, and biological factors underlying these observations.

Custom vs. prefabricated orthoses for foot pain

Compared with placebo or sham, custom-made foot orthoses modestly reduce foot pain from pes cavus (high arch), arthritis, plantar fasciitis, and painful hallux valgus. However, there is no evidence that custom orthoses are more effective than prefabricated ones.
