Development and Initial Testing of a Health-Related Independence Measure for Autistic Young Adults as Reported by...

Becoming an adult comes with education, work, living, and health-related transitions. Health care transition (HCT) services help adolescents prepare for a smooth transition to adult care, ensure health insurance retention, and promote adolescents' independent management of health care and life needs. Lack of HCT services can result in negative outcomes such as unmet needs, overmedication, and loss of decision-making authority. Autistic young adults (AYA) are half as likely to receive HCT services compared with special needs young adults. Furthermore, there are no HCT readiness measures that address the unique needs of AYA.

This study used a mixed-methods approach to develop and test a holistic caregiver-reported measure of HCT readiness for AYA Health-Related Independence (HRI). The phases used to create and test the HRI measure included: (1) construct and question topic development through qualitative data collection with AYA and caregivers; (2) question development with clinicians and caregivers; and (3) initial question testing utilizing cognitive interviews and pretesting of the instrument with caregivers.

Measure constructs were developed based on qualitative findings from AYA (n = 27) and caregivers (n = 39). The researchers identified 12 themes related to HRI from the data. Next, questions were developed for each theme by caregivers (n = 5) and clinicians (n = 25). Finally, questions and the survey format were tested using caregiver feedback in the form of cognitive interviews (n = 15) and pretests (n = 21). The final version of the caregiver-reported HRI measure included 8 constructs and 58 questions.

The development of the HRI measure was a comprehensive and iterative process. This article highlights the measurement development process and its potential impact on AYA, caregivers, and clinicians.

Why was this study done?: Health care transition services help youth keep their health insurance, transition to an adult doctor smoothly, and promote independence. To date, there is no health care transition intervention for autistic young adults. Few studies have examined how to prepare autistic young adults to manage their health and self-care needs and the transition to an adult model of care. We wanted to fill in these gaps by creating a measure of health care transition readiness for autistic young adults.What was the purpose of this study?: The purpose of the study was to develop the Health-Related Independence measure based on autistic young adult and caregiver input. We define Health-Related Independence as a young adult's ability to manage their health, healthcare, and safety needs. We also wanted to examine the measure to make sure it was easy to read, made sense, and was easy to answer.What did the researchers do?: We used a mixed-methods approach to develop and test the Health-Related Independence measure. There were three parts to the study: (1) we conducted individual interviews with autistic young adults and focus groups with caregivers to understand what topics should be included in the measure, (2) clinicians and caregivers then used those topics to create specific survey questions, (3) we conducted interviews and online pretest of the measure with caregivers.What were the results of the study?: The autistic young adults and caregivers identified twelve topics/themes to include in the Health-Related Independence Measure. Caregiver feedback helped make the measure shorter and easier to understand and complete. The final version of the caregiver-reported HRI measure included 58 questions.What do these findings add to what was already known?: We learned that young adults and caregivers have a broad understanding of health-related independence such as safety and sexuality/relationship knowledge. There weren't any measures to capture these ideas. This study created an important new measure that can be used in healthcare clinics, schools, and at home.What are potential weaknesses in the study?: This study aimed to work with autistic young adults to develop the Health-Related Independence measure, but due to funding and study limitations, we only included young adults in the 1^st phase of the study. Caregivers were used as proxy reporters in phases 2 and 3. Not including autistic young adults in phases 2 and 3 was a weakness of the study. Future research should aim to fully incorporate young adults into the research process. Their views should inform the development of the qualitative interview guides and all portions of the study.How will these findings help autistic adults now or in the future?: The Health-Related Independence measure can help caregivers and health care providers identify areas in which the autistic young adults are successful and areas of needed improvement to assist in the successful transition to adult care and adult life. The authors are currently working on a study proposal to validate the Health-Related Independence measure as a self-assessment tool for young adults to take themselves.
