Pathological Narcissism, Negative Parenting Styles and Interpersonal Forgiveness among Psychiatric Outpatients

Pathological narcissism has previously been investigated with regard to negative parenting and interpersonal forgiveness, but inconsistent findings have been obtained in relation to its two phenotypic forms - grandiosity and vulnerability. Moreover, the role of negative parenting in the lack of forgiveness within narcissistic pathology has not been explored thus far. The aim of the current research was to investigate the complex relations among pathological narcissism, negative parenting, and interpersonal forgiveness in psychiatric outpatients.

A sample of 250 adult psychiatric outpatients (61% female; mean age 39.15 years) were enrolled in this study. The participants filled out the Pathological Narcissism Inventory (PNI), the Tendency to Forgive Scale (TTF), the Measure of Parental Styles (MOPS), and the Depression, Anxiety, Stress Scales (DASS21).

Narcissistic grandiosity and narcissistic vulnerability were positively correlated with mothers' and fathers' negative parenting, but this association was significantly stronger in the case of narcissistic vulnerability. Only narcissistic vulnerability was related to interpersonal forgiveness. In the mediation analysis, negative parenting was not directly related to interpersonal forgiveness, however, this association became significant after introducing narcissistic vulnerability. Narcissistic vulnerability served as a full mediator of the mothers' and fathers' negative parenting - interpersonal forgiveness relationships.

Narcissistic vulnerability seems to be more strongly related to negative parenting and interpersonal forgiveness than narcissistic grandiosity, while it also represents one of the underlying mechanisms of the negative parenting - interpersonal forgiveness relationship. The clinical implications of these findings are discussed in relation to pathological narcissism and lack of forgiveness.
