The origins of current attachment constructs are reviewed. Whereas J. Bowlb
y's (1969/1982) original theory focused on a biobehavioral safety-regulatin
g system with the parent as the child's primary protector, current usage of
ten encompasses much more, if not all, of the parent-child relationship. As
a result, some of J. Bowlby's central ideas have not been adequately teste
d, and the unique contributions of the theory have been obscured. The autho
rs argue that differentiating protection from general responsivity or good
parenting has many advantages. Most important, it will enable researchers t
o test J. Bowlby's notion that parental protection has a singular role to p
lay in socioemotional development and has implications for attachment asses
sment and interventions in clinical work with families.
