Whether direct or indirect, parental alienation harms families

A new study by Colorado State University researcher Jennifer Harman found that mothers use more indirect alienating strategies, while fathers use a mix of direct and indirect tactics. This can lead to children's ultimate rejection of parents for false reasons, creating an 'enmeshed identity' with the alienator.
