The presence in the child's symptom display of the three characteristic diagnostic indicators (i.e., the «psychological fingerprints») of the child's psychological influence and control by a
narcissistic / (borderline)
parent represents sufficient and definitive clinical evidence that the symptomatic child - initiated cut - off of the child's relationship with the other
parent is the direct result of the pathogenic
parenting practices of a
narcissistic / (borderline)
parent (i.e., the allied and supposedly «favored»
parent), who is using the child in a role - reversal relationship as a «regulatory other» (see my
blog essay: Parental Alienation as Child Abuse: The Regulating Other) for the psychopathology of the
narcissistic / (borderline)
parent.
