The amount of time it takes for therapy to work for those experiencing childhood trauma is heavily influenced by several factors and cannot be generally predetermined. Most therapists will not be able to give you a specific timeline, at least not before a few therapy sessions since they are not able to predict how you will react to therapy or just how deep the trauma may be. Some factors that can influence the timeline of healing include what your goals with the therapy are (if you want complete deep healing or just everyday fixes for dealing with triggers), how severe your trauma is, what type of trauma you have experienced (if it was a single event or ongoing), and if the threat of trauma still lingers. It may also depend on your comfort level with your therapist and how long it takes for you to get to a level of trust with them. With all of this in mind, unless you have very base-level goals for therapy, research suggests that healing childhood trauma will most commonly take around 15 to 30 months, but the timeline should not be the goal. Healing is not something that should be rushed, take the time with your therapist that you need to ensure that you can heal and move forward from trauma in a healthy and proactive manner.
