The study investigated relations among parental (maternal and paternal) acceptance-rejection and dispositions toward forgiveness and vengeance, as mediated by psychological (mal)adjustment. Data were collected using convenience sampling from 341 adults (87% females) ranging from 18 years to above 52 years old. Measures used were short forms of the maternal and paternal Adult Parental Acceptance-Rejection Questionnaires (PARQ) to investigate recollections of parental acceptance-rejection, the short form of the Adult Personality Assessment Questionnaire (PAQ) to evaluate which participants were psychologically (mal)adjusted, the Heartland Forgiveness Scale (HFS), the Vengeance Scale (VS-10) to investigate levels of forgiveness and vengeance respectively, and a Personal Information Form (PIF). The results indicated that participants perceived significant signs of paternal rejection and substantial maternal acceptance during childhood. Men and women self-reported fair psychological adjustment. Women reported having no disposition toward vengeance, whereas men slightly leaned toward vengeance. Participants were equally likely to be unforgiving as forgiving. Psychological adjustment mediated the relations between maternal acceptance (but not paternal acceptance) and forgiveness among men and women. Psychological maladjustment mediated the relations between maternal rejection and vengeance among women, but not men. Psychological maladjustment did not mediate relations between paternal rejection and vengeance. Limitations and implications of the findings are discussed.
