Understanding Behavioural Responses to Trauma

Tamari Thompson-Kraft • Mar 30, 2022

I'm not acting like myself. Will it always be this way?

As we’ve explored in this 4-part series, trauma is a persistent physical, cognitive, emotional or existential response that occurs after experiencing a distressing event or series of events (CAMH, 2022). We don’t know all the causes and manifestations of trauma, but the impact of trauma on a person’s life can be profound.


In many cases, the client may not even realize how many parts of their being have reacted to a traumatic event. As Counsellors and Psychotherapists, we want to help you explore the effects of trauma so that we can use appropriate treatments and help you reset your life.


Behavioural Reactions to Trauma   

A person’s behavioural responses to trauma may change over time. Immediately after a traumatic event, a person might feel like their behaviour is unlike their usual self—routines interrupted, acting differently, having a hard time regulating some behaviours. Many feel that their thoughts and behaviours are out of sync. This response is comparable to a cartoon character’s legs running faster than its body. Over time, some of those behaviours might settle into healthy coping strategies while other behavioural patterns may become problematic and difficult to shake.


Immediate Behavioural Reactions

  • Startled reaction
  • Restlessness
  • Sleep and appetite disturbances
  • Difficulty expressing oneself
  • Argumentative behavior
  • Increased use of alcohol, drugs, and tobacco
  • Withdrawal and apathy
  • Avoidant behaviors


Delayed Behavioural Reactions

  • Avoidance of event reminders
  • Social relationship disturbances
  • Decreased activity level
  • Engagement in high-risk behaviors
  • Increased use of alcohol and drugs
  • Withdrawal


Addressing Behavioural Reactions to Trauma

These behavioural reactions to trauma may be all too familiar. Everyone responds to trauma differently, but for many people, trauma-induced behaviours can become unhealthy coping methods. In the short term avoidant, explosive or evasive behaviours may be necessary as a means of self-protection. However, over time some behaviours can become habitual and difficult to change or manage. There are many ways to address these symptoms so that you can hit the reset button and feel more like yourself.
