This study aims to develop an attachment-based parental education program and its application to enhance
parenting sensitivity and attachment security. A total of 25 care-givers, raising 24-36-month-old toddlers,
participated in 8 sessions of attachment-based parental education program. Pre- and post-intervention data
were collected and analyzed using Wilcoxon signed-rank test to investigate effects of the intervention,
Mann-Whitney U test to verify the levels of parental stress, maternal depression, and toddler's
temperament resulting in the effects of the intervention. There were significant effects on enhancing
parental sensitivity and attachment security in participants. Furthermore, there were significant group
differences in parenting sensitivity between those who recorded high and low score on dysfunctional
parent-child interaction subscale on parenting stress, and those who reported high and low depression
levels. Participants who believed that their child has a difficult temperament showed a more significant
change in attachment security than those who did not. This study demonstrated effects of
attachment-based parental education program for enhancing parenting sensitivity and attachment security to
care-givers in general population.
