Psychometric testing of a set of patient-reported instruments to assess healthcare interventions for autistic adults.

LAY ABSTRACT: Interventions to improve healthcare for autistic adults are greatly needed. To evaluate such interventions, researchers often use surveys to collect data from autistic adults (or sometimes, their supporters), but few survey measures have been tested for use with autistic adults. Our objective was to create and test a set of patient- or proxy-reported survey measures for use in studies that evaluate healthcare interventions. We used a community-based participatory research (CBPR) approach, in partnership with autistic adults, healthcare providers, and supporters. We worked together to create or adapt survey measures. Three survey measures focus on things that interventions may try to change directly: (1) how prepared patients are for visits; (2) how confident they feel in managing their health and healthcare; and (3) how well the healthcare system is making the accommodations patients feel they need. The other measures focus on the outcomes that interventions may hope to achieve: (4) improved patient-provider communication; (5) reduced barriers to care; and (6) reduced unmet healthcare needs. We then tested these measures in a survey of 244 autistic adults recruited from 12 primary care clinics in Oregon and California, USA (with 194 participating directly and 50 participating via a proxy reporter). Community partners made sure items were easy to understand and captured what was important about the underlying idea. We found the survey measures worked well in this sample. These measures may help researchers evaluate new healthcare interventions. Future research needs to assess whether interventions improve healthcare outcomes in autistic adults.

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.
