Psycho-physiological trauma theory postulates that trauma can cause nervous system dysregulation, which has not been considered with evidence-based treatments. Other models, including the community resiliency model, have focused on reducing nervous system dysregulation. This study used a comparison group in a pre-test post-test model to examine the difference between participants with post-traumatic stress disorder symptoms who did and did not receive model training. Eighteen adult subjects were non-randomly assigned to control and treatment groups. The frequency and severity of intrusive symptoms, avoidance/numbing symptoms, and hyperarousal symptoms were measured by the Davidson Trauma Scale. Data were collected at pre-treatment, immediately following treatment, and one week after treatment. Three separate mixed ANOVAs were run to assess the effect of CRM treatment over time. The dependent variables were derived from the Davidson Trauma Scale’s three subscales, Intrusive, Avoidance/Numbing, and Hyperarousal. Initial analyses revealed a significant main effect of time, but no main effect of treatment, across all three variables. However, a significant interaction was evident for all three subscales, warranting follow-up analyses. For all three dependent variables, the pretest means were significantly greater for the treatment group than for the control group. These differences may reflect the non-random assignment of participants to the control group.
