The purpose of this study was to examine what aspects of the mother-ch
ild relationship are measured by the Nursing Child Assessment Teaching
kale (NCATS). A racially heterogeneous sample of 128 mothers complete
d questionnaires measuring maternal depression, parenting self-efficac
y, knowledge of developmental and parenting principles, and perceived
difficult toddler temperament. Mothers and children were also videotap
ed during home visits while completing two teaching tasks that were la
ter scored using the NCATS. NCATS Parent subscale scores were signific
antly related to maternal knowledge and education but unrelated to dep
ression and self-efficacy. Child subscale scores were unrelated to all
of the study variables, including perceived difficult temperament. Si
gnificant differences were noted among African-Americans, Hispanic, an
d white mothers. The findings suggest that the NCATS taps cognitive fa
ctors more reliably than affective factors underlying the mother-child
relationship and the cognitive factors may be culturally biased.
