The therapist will observe and guide how the teen wants to take the session but in an appropriate way. The psychologist will provide security for the teen to feel comfortable and this will tell in a couple of sessions for the teen to reach to that stage. After a couple of sessions, the therapist aim is to clear out the teen’s thoughts of what they went through in the event of the incident. On the last session, the therapist will ask the teen to remove the fears and worries and the negative thoughts that are running through their mind.
