Hypothesis One: That the test scores of clients who completed the
clinical program at Victims Services Center indicate significant reductions in traumatic stress symptoms, depression and anxiety.
Hypothesis Two: That the test scores of clients who completed the clinical program at Victims Services Center indicate significant improvement in General Expectancy of Success.
Hypothesis Three: That there is a correlation between reduction of traumatic stress indicators (IES R Scores) and an increase in the Trauma Recovery Scale.
Hypothesis Four: That clients with a reported history of trauma and victimization required more hours of service.
Hypothesis Five: That those who reported earlier victimization were more likely to be current victims of domestic violence.
Results:
Using Repeated Measures Analysis of Variance, Hypotheses 1 and 2 were supported. That is, from Time 1 to Time three, participants showed consistent and significant improvements in traumatic stress symptoms (Intrusive,Avoidance, Hyperarousal), depression, and anxiety. Further, significant increases were demonstrated for the General Expectancy of Success measure. These significant results occurred from one Time to the next for all measures except for the GES, where significant differences were only observed from Time 1 to Time 2 and from Time 1 to Time 3. This demonstrates that to see a marked improvement in GES scores, the GES need only be administered at baseline
and Time 2.
Hypothesis 3 found moderate support and was assessed using correlational analysis. First, difference scores were computed subtracting Time 1 scores from Time 3 scores for each of the 4 variables (Intrusive, Avoidance,Hyperarousal, Trauma Recovery Scale). The expected negative relationship between TRS and Intrusive (r=-.596, p<.01) as well as between TRS and Hyperarousal (r=-.654, p<.01) were supported. The expected negative relationship between TRS and Avoidance, however, was not significant (r=.179, p>.05). Therefore, there is a correlation between a reduction in 2 of the 3 Trauma Stress Indicators and an increase in TRS scores.
In Hypothesis 4, it was expected that clients with a reported history of trauma and victimization required more hours of service. Reported trauma history was used in linear regression analysis as the predictor for the number of hours of service (the dependent variable). The analyses showed that there was no significant relationship between history of victimization and number of hours of service.
Hypothesis 5, that those who reported earlier victimization were more likely to be current victims of domestic violence, was not supported by the data. History of victimization was a dichotomized variable and the crime variable was recoded such that those who reported being current victims of domestic violence received a designation of “1” and all other reported crimes were designated “0”; thus, crime also became a dichotomized variable. Chi-square analysis showed no significant difference, where those who did and did not report a history of victimization were equally likely to become victims of domestic violence.
