Scores on parent-report of child competency through BITSEA. A higher score indicates greater perceived competency. There is a significant difference in competency scores between VUS and Normal/LB parents at 12 months (p=0.04), though not 36 months (p=0.37). Scores for the normal/LB and VUS groups increased from 12 to 36 months, (β =2.61, p<0.0001, and β =4.12, p<0.0001, respectively), but the VUS group’s scores increased significantly more (p=0.05).
