Increasingly, interventions are being developed and tested with families of color, including Latino families of transition-aged youth with autism. However, without culturally responsive measures, it is difficult to determine whether an intervention is effective. The purpose of this study was to improve the cultural responsiveness of measures related to: knowledge of adult disability services, advocacy, and family empowerment. Altogether, 30 Latinx parents of youth with autism participated in this study. Participants completed surveys and interviews to inform changes to the measures. Changes were made in relation to: wording, format, and concepts. The revised measures were demonstrated to have high reliability. Implications for future research and practice are discussed.
