Problem Set 2: The Two-factor ANOVA for Independent Measures Research Scenario: Counselors at a substance abuse clinic are interested in the differential effects of opioid dependence counseling for different types of clients. In particular, they have read that there may be differences in treatment response based on whether prescription opioid- dependent clients have a history of chronic pain and/or heroin use (i.e. Weiss, Potter, Fillin Byme, Connery, Dickinson, et al., 2011). To test this theory in their own clinic, they divided new clients based on whether or not they had a history of chronic pain > 6 months) and whether or not they had a history of heroin use (used at least 1 time). All clients were treated over 16 weeks with a combination of buprenorphine-naloxone stabilization treatment plus twice weekly individual opioid dependence counseling. Each client was asked to submit urine and report how many times they had used opioids during a l-week period, each week for 16 weeks. As a first pass through the data, the counselors added the 16 weekly reports for each client to get one overall count of opioid use (i.e. if a 20 is recorded, it means the client reported using opioids 20 times over the 16-week period). The results are in the table below. Based on the data, is there an effect of history of pain or heroin use on subsequent opioid use during treatment? Using this table, enter the data into a new SPSS data file and run a two-way ANOVA to test whether there is an effect of pain history or heroin use on treatment outcome, as measured by the number of times using opioids during treatment. Create a multiple line graph to show the difference among these scores. No history of chronic pain History of chronic pain No history of heroin use History of heroin use 1.
