Several attachment-based intervention studies have been performed, wit
h varying success. An important question is whether short-term interve
ntions can be successful in promoting parental sensitivity and securit
y of infant-parent attachment as well as in changing parental represen
tations of attachment. We investigated this issue in an exploratory wa
y in a case study. A short-term home-based intervention with written m
aterial and video feedback, which was effective regarding parental sen
sitivity and infant security in a former study, was provided a parent
who revealed an insecure attachment representation in the Adult Attach
ment Interview. The intervention sessions mere expanded with discussio
ns about past and present experiences of attachment. After four interv
ention sessions the mother's behavior towards her child was rated as m
ore sensitive than before the intervention. Also, the infant-mother at
tachment, as observed in the Strange Situation, appeared to be more se
cure. Nevertheless, in a second Adult Attachment interview administere
d after the intervention, the mother showed again an insecure represen
tation of attachment. Possible implications of these results are discu
ssed.
