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

Developing and Psychometric Testing a Health Care Transition Service Measure in the National Survey of Children's Health

OBJECTIVE

Access to health care transition (HCT) services has been included in national surveys for 20 years. While dozens of studies have assessed HCT, no study has examined the model fit of the HCT questions or psychometric properties of the measure. We utilized National Survey of Children's Health (NSCH) data to develop and test a comprehensive HCT measure.

METHODS

We utilized NSCH data (2016-19) to examine the model fit of 9 HCT questions. The new measure's psychometric properties were assessed by comparing it to theoretically similar and divergent variables including receiving care coordination/help, shared-decision making, satisfaction with communication, preventative dental care, and volunteer experience.

RESULTS

An exploratory factor analysis and item culling yielded 8 items addressing 3 subscales. A confirmatory factor analysis on separate data confirmed the identified subscales. A dichotomous and continuous scale was created with subscales including Guidance Toward Independence, Adequate Clinic Visit, and Continuity of Care Discussions. Model fit was excellent with an Eigenvalue of 1.08% and 89% variance explained in exploratory factor analysis and a Goodness of Fit index of 0.97 in confirmatory factor analysis. Examination of initial reliability and content and criterion validity indicated high reliability and validity for the scale and subscales.

CONCLUSIONS

This was the first study to examine the psychometric properties of the HCT measure in the NSCH. The HCT measure identified in this study assesses providers' use of care plans, promotion of independence, clinic visit quality, and transfer assistance. This measure will be a useful tool in clinics, intervention development, and research for adolescents with and without special health care needs.retain-->.

Measuring health care transition: Across time and into the future

PROBLEM

Youth with special health care needs often experience significant difficulty transitioning into adult health care services and adult life. Services supporting youths' transition from pediatric to adult health care (Health Care Transition (HCT)) have been a priority for nearly 30 years to improve this transition process. The Health Resources and Service Administration, Maternal and Child Health Bureau have measured HCT service provision since 2001 but the longitudinal use of this measure has never been examined (Blumberg, 2003; Maternal and Child Health Bureau, n.d.).

ELIGIBILITY CRITERIA

This manuscript highlights the consistent and inconsistent uses of HCT constructs in two prominent national surveys (the National Survey of Children with Special Health Care Needs (NS-CSHCN) and the National Survey of Children's Health (NSCH)) between 2001 and 2019. All studies utilizing an HCT measure within a national survey between the 18 years were included in this examination.

RESULTS

Significant changes have been made to the measurement of HCT service provision resulting in inconsistencies over the last 18 years. Measurement criteria and survey questions have changed substantially from the NS-CSHCN and NSCH limiting one's ability to examine trends in HCT since 2001. Since 2016, few changes have been made, allowing for analysis of trends over time. Importantly, the NSCH includes added questions pertaining to HCT that are not included in the composite HCT outcome measure.

CONCLUSION

Future work should include a validation study of the HCT outcome in the National Survey of Children's Health and inclusion of additional HCT questions to promote continued and extensive use of a measure that more fully represents the needs of youth and their families.

Validation of the Health-Related Independence for Young Adults with Autism Spectrum Disorder Measure- Caregiver Version

Little is known about Young adults with Autism Spectrum Disorder (YA-ASD) health, healthcare and safety needs. This study describes the validation of a health care transition measure for YA-ASD, the Health-Related Independence (HRI). We collected data from caregivers (n = 490) at five Autism Treatment Network sites and compared the psychometric properties of HRI to the gold standard (STAR_x) and other validated measures. A Confirmatory Factor Analysis and item culling resulted in 30 items addressing six subscales. Content, criterion, and construct validity and internal consistency indicated high validity and reliability for the scale and subscales. HRI is a validated caregiver-report measure of YA-ASD's self-management, safety, and transition skills. This novel measure will be a useful tool in clinics, intervention development, and research.
