The Parental Bonding Instrument (PBI), a measure of perceived parental care
and protection, was administered to drug-dependent patients and their pare
nts with the aim to assess the reliability of the instrument in such sample
s and to compare the parental representations across generations. Ninety dr
ug-dependent patients and 44 mothers and 35 fathers participated. Reliabili
ty indices were calculated, and parental representations of parents and the
ir offspring were compared. Linear regression analyses were performed with
the patient's PBI score as the dependent variable and the mother's and fath
er's PBI scores as predictor variables. The reliability indices were highly
satisfactory and varied between 0.61 and 0.91, The parental bonding of pat
ients, fathers, and mothers was similar. All three groups reported high mat
ernal and paternal control and low maternal care, a pattern characteristic
of an "affectionless control" rearing style. Maternal care received by the
fathers and paternal protection received by the mothers predicted the care:
and protection they themselves gave to their drug-dependent offspring. Cop
