Unformatted text preview: h (see Figure 3a and b). To further examine this interaction, analyses were conducted separately for the high- and low-risk groups. Parental responsiveness predicted telomere length among high-risk children, with more responsive parenting associated with longer telomeres (r ¼ .35, p , .05) but not among low-risk children (r ¼ –.10, p . .05). The results remained significant when excluding the second child of the two sibling pairs. Discussion Telomere length was significantly shorter in high-risk children with previous involvement in the Child Welfare System, relative to low-risk comparison children. Further, parental responsiveness moderated the association between early adversity and telomere length, with higher parental responsiveness predicting longer telomeres only among high-risk children. These findings remained significant after controlling for household income, birth weight, gender, and minority status. Taken together, these findings support the critical role of Parental responsiveness and telomere length. Multiple linear high-quality parenting behavior in modifying the biological regression analyses were conducted to examine the associaimpact of early-life stress. tion between parental responsiveness and telomere length.
