In the 1990s research was done which found that two-thirds of people experienced at least one of the above traumas in childhood. Over 12% experienced 4 or more. As society has increasingly fractured this has only grown further.
Gabor Maté produced a wonderful documentary The Wisdom of Trauma, which showcases the recognition of trauma informed therapy today. Its well worth a look and something I recommend to my clients who are going through their healing processes.
