Post your explanation of what you think the social workers wanted to know when they designed thepre/posttest for evaluating the parenting classes. Be sure to address the concept of attrition andwhether or not you believe they took that into account. Be sure to explain why. Then, analyzepotential lessons learned from attrition. Finally, explain how you might design a study to gather dataabout the eff ectiveness of these parenting classes. Use the following questions to focus yourthinking: Would you recommend a pre-experimental, experimental, or quasi-experimental design?
Would the study involve measurement over time?
Would there be a control group? 0 In this group research design you imagine, what or who will be compared?
What limitations in terms of generalizability and internal validity can you anticipate based on the research plan you envision?
What can you tell the social worker about the issue of client drop out (also called attrition or experimental mortality)?
If there is no control group, what type of research design could answer the question:
Is this parent training class effective in reducing abusive parenting practices?
