"Our findings challenge widely held beliefs about how child abuse should be recognized and treated—a responsibility that often lies with the physician. Because different types of child abuse have equivalent, broad, and universal effects, effective treatments for maltreatment of any sort are likely to have comprehensive psychological benefits. Population-level prevention and intervention strategies should emphasize emotional abuse, which occurs with high frequency but is less punishable than other types of child maltreatment". And also "Finally, population-level prevention and intervention strategies should not ignore the considerable psychological harms imposed by emotional abuse, which rival those of physical abuse and neglect. Taken together with high worldwide prevalence and evidence that emotional and physical pain share a common somatosensory representa-ion in the brain, it is clear that emotional abuse is wide-spread, painful, and destructive."

It was also noted that “The psychological foundations of parental alienation – lack of empathy and inability to tolerate the child’s separate needs and perception – is also the foundation of psychological maltreatment” p. 473.

British Psychological Society (BPS). "Parental alienation: Why a better understanding is needed in the British family justice system." ScienceDaily. ScienceDaily, 13 July 2014. "Despite recognition in recent high court judgements, it is poorly understood and rarely acknowledged in the British family justice system." "Dr Whitcombe will explain that the denigration and ultimate rejection of a parent in parental alienation is a psychological defence mechanism. Unable to manage the cognitive dissonance of their positive experience of a loving parent and the explicit or implicit negative messages they receive from the other parent, the child's immediate psychological distress is minimised by rejecting one parent."
Gordon 1998 "MMPI-2 Findings of Primitive Defenses in Alienating Parents" .... 158 MMPIs .... "We found that mothers and fathers who were alienators had higher (clinical range) scores indicating primitive defenses such as splitting and projective identification, than control mothers and fathers (normal range scores) in both our indexes. Target parents were mostly similar to the control parents. The results showed strong support for Gardner’s definition of PAS."
