The purpose of this study was to examine the role of perceived parenting behavior in the childhood of patients with pathological gambling disorder (PGD). Thirty-three outpatient subjects with DSM-IV pathological gambling disorder, and no other current Axis I disorders, completed the Parental Bonding Instrument (PBI), which measures subjects' recollections of parenting on dimensions of care and protection. PBI scores of pathological gamblers were compared to normal controls. Subjects with PGD had significantly lower maternal and paternal care scores than the control subjects (22.6 +/- 8.9 vs. 26.9 +/- 7.3 on maternal care [p = 0.010], and 17.4 +/- 9.6 vs. 23.8 +/- 7.6 on paternal care [p = 0.001]). In terms of parental bonding patterns based on a combination of care and protection, the pathological gamblers reported low rates of optimal parenting and high rates of neglectful parenting. These preliminary findings suggest that neglectful parenting appears to be associated with pathological gambling disorder.
