Bond breaking theory

Social Bond Theory | Criminology Wiki | Fandom

Social Bond Theory - The Social Bond theory was created by Travis Hirschi in 1969. Social Bond theory, that later developed into the Social Control Theory, has historically been an interesting way of approaching social problems and how we in turn explain them. Before one can apply Social Bond theory, they must first have a firm understanding of its definition, which can be accurately described ...

Trauma Bonding: How To Release A Trauma Bond

Breaking trauma bonds. The reason it feels like you can''t "break" a traumatic bond is because you are still suffering from your body''s adaptations to all of this chaotic, negative energy that is now stored inside. These very adaptations cause you to constantly review what happened, to fixate, to refrain from feeling fear and grief, and ...
