Question

Problem Set 2: Research Scenario: In a clinic that focuses on helping victims of domestic minor sex trafficking (DMST), a team of social workers wants to compare the differential effects of treatments for complex trauma. They divide 21 participants into three groups (n = 7 each) that do not differ significantly from one another in terms of pre-treatment trauma symptomology. One group receives Trauma-Focused Cognitive-Behavioral Therapy (TFCBT), one receives Experiential Group Therapy (EGT), and one receives a combination of the two (TF+EG). Participants' complex trauma symptoms are evaluated after treatment using a clinician interview where scores range from 0-30 and higher scores indicate a higher severity of trauma. The scores are listed in the table below. Is there a difference in post-treatment trauma scores among the three treatments? Using this table, enter the data into a new SPSS data file. Use the appropriate test to analyze the question and create the appropriate graph. 2. EGT3 3. TF+EG 1. TFCBT 23 17 18 6 20 14 1921 1. Paste SPSS output. (6 pts) 2. Write an APA-style Results section based on your analysis. Include your graph as an APA-style figure as demonstrated in the APA writing presentations. (Results 6 pts Graph = 4 pts)

The hypothesis being tested is: Ho: = was Hy: At least one means is not equal The p-value from the output is 0.984. Since the p-value (0.984) is greater than the significance level (0.05), we cannot reject the null hypothesis Therefore, we cannot conclude that there is a difference in post-treatment trauma scores among the three treatments
