Comparing the Impact of Peer Support vs. Staff-Delivered Transportation Interventions for Young Adults With Intellectual and Developmental Disabilities.

Overview

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. 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. Both groups will learn the same amount of travel skills. 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.

This clinical trial has 2 aims. Aim 1. Compare the effectiveness of peer support (R2R-PS) or staff delivered (R2R-S) Ready to Ride (R2R) travel intervention on loneliness, satisfaction with social activities, and travel skills (primary outcomes), and service use/access, transportation use, employment, social connectedness, and health related quality of life (secondary outcomes) for YA with IDD. Hypothesis 1.1: YA receiving R2R-PS will report significantly higher satisfaction with social activities, increased social connectedness, and significantly less loneliness compared to YA receiving R2R-S. Hypothesis 1.2: The travel skills demonstrated by YA receiving R2R-PS will be no worse than travel skills demonstrated by YA receiving R2R-S. We use a non-inferiority approach in response to community service organizations' request for evidence that peer support delivery does not lead to poor outcomes. Hypothesis 1.3: YA receiving R2R-PS will demonstrate significantly greater improvements in service use/access, transportation use, employment, and health related quality of life 4 months post intervention compared to YA receiving R2R-S. Aim 2: Evaluate heterogeneity of treatment response by assessing differences in R2R outcomes across characteristics of groups (race and ethnicity, anxiety, adaptive behavior) and context (transportation availability). Hypothesis 2.1. There will be no difference in treatment effect for YA who identify as white, non-Hispanic and those identifying as Black, Hispanic, Asian, or other race/ethnicity. Hypothesis 2.2. There will be greater gains for YA with lower levels of adaptive behavior completing R2R, based on past research that identified that participants with intellectual disabilities (ID) with lower levels of adaptive behaviors demonstrated greater improvements in transportation skills than those with a developmental disability but without an ID after receiving the R2R intervention.37 Hypothesis 2.3. There will be no difference in primary outcomes for YA living in areas with less transportation availability, given R2R's individualized travel training approach. Hypothesis 2.4. There will be greater gains for YA in transportation outcomes who report lower levels of anxiety, given that anxiety in linked with reduced transportation use.
