Brief Summary

This clinical trial will look at whether young adults with intellectual and developmental disabilities (YA-IDD) have better outcomes when a travel training intervention called Ready to Ride (R2R) is taught by a specially trained Peer Supporter (PS) who shares the lived experience of having an IDD than YA-IDD who are taught Ready to Ride by staff at their community services organization. The aspects of life being looked at are loneliness, satisfaction with social activities, travel skills, service use and access, employment, and health related quality of life. The researchers think the following things will happen.

1. 1.YA-IDD who learn from a Peer Supporter will report significantly higher satisfaction with social activities, increased social connectedness and significantly less loneliness compared to YA who are taught organization staff.
2. 2.Both groups will learn the same amount of travel skills.
3. 3.YA-IDD who learn from a Peer Supporter will show larger increases in access to community-based services, transportation use, employment and health related services after 4 months than the YA taught by organizational staff.

Outcome Measures

Primary Outcomes (3)

• Progressive Evaluation of Travel Skills (PETS)

  The Progressive Evaluation of Travel Skills (PETS) ) is a direct observation measure of independent travel, as rated by the level of support needed for participants to complete transportation-related skills. This tool has established content and construct validity with people with IDD. The PETS will be administered by research staff masked to group assignment who will evaluate each participant on a standardized route. The standardized routes have comparable difficulties across local public transportation systems.

  Data will be collected at 3 time points: 1) pre-test (<14 days prior to R2R), 2) post-test 1 (within 4 days of R2R completion) and 3) post-test 2 (4 months after R2R completion).

• NIH Toolbox® Item Bank v3.0 - Loneliness (Ages 18+) - Fixed Form (PROM)

  Loneliness-NIH Toolbox® Item Bank v3.0 has 5 questions rated on a 5-point scale. This measure has acceptable psychometric properties in the general population and is used in clinical populations and with people with disabilities, including IDD. The tool includes questions that have detected differences in loneliness between individuals with and without IDD. A total standard T-score will be used to analyze the data.

  Data will be collected at 3 time points: 1) pre-test (<14 days prior to R2R), 2) post-test 1 (within 4 days of R2R completion) and 3) post-test 2 (4 months after R2R completion).

• PROMIS Short Form v1.0 - Satisfaction with Participation in Discretionary Social Activities 7a (PROM)

  Satisfaction with Participation in Discretionary Social Activities-PROMIS Short Form v1.0 has 7 items that assess contentment with leisure interests and relationships with friends. It has been used with adults with a range of disabilities, including IDD. In a study with people with disabilities (including IDD), increased access to transportation predicted higher scores on this measure. A total standard T-score will be used to analyze the data.

  Data will be collected at 3 time points: 1) pre-test (<14 days prior to R2R), 2) post-test 1 (within 4 days of R2R completion) and 3) post-test 2 (4 months after R2R completion).

Secondary Outcomes (6)

• Service attendance

  Data will be collected at pre-testing retrospectively and then weekly after pre-test (<14 days prior to R2R) through post-test 2 (4 months after R2R completion).

• Accessibility Subscale of the Perceived Access of Health Care Services (PROM)

  Data will be collected at 2 time points: 1) pre-test (<14 days prior to R2R) and 2) post-test 2 (4 months after R2R completion).

• Transportation Use

  Data will be collected weekly during R2R intervention through post-test 2 (4 months after R2R completion).

• Self-Reported Employment Data (status, hours/week, wages, percentage of missed work shifts)

  Data will be collected at 2 time points: 1) pre-test (<14 days prior to R2R) and 2) post-test 2 (4 months after R2R completion).

• Quality of Life Questionnaire (QOL-Q)

  Data will be collected at 3 time points: 1) pre-test (<14 days prior to R2R), 2) post-test 1 (within 4 days of R2R completion) and 3) post-test 2 (4 months after R2R completion).

Other Outcomes (3)

• Adaptive Behavior Assessment System - Third Edition (ABAS-3 )

  Data will be collected during pre-test (<14 days prior to R2R).

• PROMIS Anxiety Short Form

  Data will be collected at pre-test (<14 days prior to R2R).

• Comprehensive Demographic Questionnaire

  Data will be collected at pre-test (<14 days prior to R2R).

Interventions

Ready to Ride - Standard Delivery BEHAVIORAL

The standard delivery will be implemented by non-peer staff serving as interventionists. These staff will deliver the Ready to Ride (R2R) training, an established evidence-based travel training program. The intervention includes a total of 16 sessions. Six sessions consist of structured lessons focused on travel safety, awareness, preparedness, and skill development. The remaining sessions involve community-based learning, where participants practice travel skills in real-world settings with varying levels of support provided by the interventionist.

Standard Delivery (R2R-S)

Ready to Ride - Peer Support Delivery BEHAVIORAL

The peer support delivery will be implemented by trained peer interventionists. Peer interventionists are individuals with lived experience of disability who are trained to provide structured support while sharing their experiences. They will deliver the Ready to Ride (R2R) training, an established evidence-based travel training program. The intervention includes a total of 16 sessions. Six sessions consist of structured lessons focused on travel safety, awareness, preparedness, and skill development. The remaining sessions involve community-based learning, where participants practice travel skills in real-world settings with varying levels of support. Peer interventionists will provide support through modeling, shared experience, encouragement, and guided practice.

• Access Criteria: We will be self-publishing the data through the openICPSR research data-sharing service (www.openicpsr.org) which is accessible to anyone, as it is a publicly available dataset. The dataset will be publicly accessible upon embargo expiration. Users will be required to cite the dataset and adhere to ethical use standards. If the repository requires a click-through data-use statement, we will enable it to reinforce responsible use.
