Suppose you conduct an experiment evaluating the effectiveness of an intervention for people with the co-morbid diagnoses of schizophrenia and substance abuse. Treatment outcome is measured based on whether they get arrested for substance abuse or get psychiatrically hospitalized during a specified time period. Suppose your experimental group has a high rate of attrition. Of the 50 clients assigned to that group, 10 clients drop out very early in treatment, 5 drop out in the middle of treatment, and 5 drop out near the completion of treatment. In contrast, none of your control group participants drop out of the study. Answer the following questions:
a. What rationale could be cited for including the dropouts in the analysis of outcome data?
b. What rationale could be cited for excluding the dropouts from that analysis?
c. What rational could be cited for including some of the dropouts in the analysis and excluding others?
d. Which of the three dropout data analysis options (in a,b,and c) would you choose? Why?
