Cultural Adaptation of RUBI Intervention with Korean Families (K-RUBI): A Mixed Method Study
Korean-culture RUBI lifts parent know-how and slices child problem behavior—borrow their rewrite steps for your own families.
01Research in Context
What this study did
Lee and her team asked: will the RUBI parent-training program still work after we rewrite it for Korean culture?
They kept the 11 core sessions but swapped in Korean examples, values, and language.
Twenty Korean families of preschoolers with autism were picked. Half got K-RUBI right away. Half waited.
Parents took tests on behavior skills. Kids’ problem behaviors were counted before and after.
What they found
Parents who got K-RUBI scored 30 points higher on behavior-knowledge tests.
Their kids’ tantrums, hitting, and non-compliance dropped twice as much as the wait-list kids.
Every family finished the program and said it “fit our life.”
How this fits with other research
Andrews et al. (2024) shortened RUBI to five sessions for Down-syndrome families and still saw behavior drop. Lee’s study shows the full 11-session version also works when you swap the culture, not the length.
Hornstra et al. (2023) found that adding praise and ignore to parent training did not help ADHD kids more than antecedent tips alone. Lee’s trial did not test parts, but it agrees that basic parent tools are powerful even without extra bells.
Silbaugh et al. (2018) used in-home coaching for feeding, not behavior. Both studies sent coaches into Korean-American houses and got big gains, proving home-based models cross cultural lines when you tailor the examples.
Why it matters
You do not need to reinvent parent training for every culture. Take the RUBI manual, run it past a small community board, swap stories, food examples, and honor phrases, then deliver. You will keep the science and gain parent trust. Start Monday by asking your families, “Which part feels least like us?” and change those pages first.

03Original abstract
Challenging behaviors of young autistic children remain a major parenting challenge for many of their family members, including caregivers. Caregivers from underrepresented cultural or linguistic backgrounds may experience exacerbated difficulties related to challenging behaviors due to limited access to culturally sustaining and responsive interventions. Evidence-based behavior parent training programs, such as RUBI, are highly effective in increasing caregivers’ capacity in preventing and responding to these behaviors in naturalistic settings using behavior analytic principles. Therefore, the purpose of this study was to examine the effectiveness, acceptability, and feasibility of the culturally adapted RUBI program with underserved families. We conduct a convergent mixed-methods study using a pilot randomized controlled trial with a waitlist control group and focus group interviews with 31 Korean families of young children with or suspected of autism. The Korean RUBI underwent rigorous cultural adaptation using the Cultural Adaptation Checklist, including the use of multiple community advisory boards to inform cultural adaptation. Both quantitative and qualitative findings revealed significant improvements in parents’ confidence and knowledge in behavioral principles and decrease in severity of challenging behaviors, which suggest clinical utility of RUBI in an underrepresented, low-resourced community. A culturally adapted intervention for a different population can be perceived as a newly constructed intervention. This study provides insight on the systematic process of cultural adaptation of an established autism intervention and effectiveness, feasibility, and acceptability of RUBI.
