Young adults with disabilities have fewer opportunities than others of the same age group to develop useful social skills needed during the transition into adulthood. This paper introduces the outcomes of a group intervention (12 months) focusing on the development of such social skills and involving 10 young adults aged from 16 to 21. Statistical analysis of data gathered from participants and their parents shows a significant positive difference (p &lt; 0.05) between the beginning and the completion of the intervention (T0-T2) regarding their possibility to achieve some life habits (mobility, responsibilities, nutrition, personal care). The intervention also improved (p &lt; 0.05) their self-efficacy, but not their self-esteem. These results are probably partially explained by the chosen mean of intervention (youth centered and focusing on in vivo learnings) that could be preferred with this profile of young adults with disabilities.
