Week 5
Once you have a fairly narrow research question and have
conducted a thorough literature review, the next step is to turn
your attention to the research design. The research design is
simply a plan for how you will conduct your research, as it
informs each step of the research process. In addition to
research design, you are introduced to the concepts of internal
and external validity and generalizability. During the latter half
of the week, you focus on a particular instrument of
measurement: the pretest and posttest. Capturing information
from research study participants both before and after a
particular event can yield priceless data.
Learning Objectives
Students will:
Classify types of group research designs
Analyze possible study limitations
Analyze relative internal and external validity
Analyze generalizability
Analyze a pretest–posttest in a case study
Evaluate research designs to assess program effectiveness
Analyze potential lessons learned from attrition
Group Research Designs for Social Work Knowledge

Discussion 1
One page paper
There are several different types of research designs. Each
design is intended to respond to a particular type of research
question. The type of research design depends on the type of
research questions asked. For this Discussion, select one of the
articles from the reading list and consider several classifications
of group research designs.
Post
your response to the following: Describe which groups are
compared in the research. Then, classify the research design as
follows:
By explaining whether the study is pre-experimental (cross-
sectional, one-shot case study, and longitudinal), experimental
(control group with pretest and posttest, posttest only, or four-
group design), or quasi-experimental (comparing one group to
itself at different times or comparing two different groups)
By indicating what the researchers report about limitations of
the study
By explaining concerns you have regarding internal validity and
the ability of the study to draw conclusions about causality
By explaining any concerns you have about the generalizability
of the study (external validity) and what aspect of the research
design might limit generalizability
Please use the resources to support your answer.

Discussion 2

Discussion 2: Pretests/Posttests and Attrition
This week's video introduces you to the Hernandez family. Juan
and Elena Hernandez are mandated to attend parenting classes.
As part of the parenting classes, they are required to participate
in both a pretest (taken before classes begin) and a posttest
(taken after classes end). Pretests and posttests can yield very
useful information. They can measure the learning that has or
has not taken place as a result of the education being provided.
For this Discussion, imagine what kinds of questions would be
on a pretest and posttest for this particular study sample (the
parents who are taking parenting classes).
Post
your explanation of what you think the social workers wanted
to know when they designed the pre/posttest for evaluating the
parenting classes. Be sure to address the concept of attrition and
whether or not you believe they took that into account. Be sure
to explain why. Then, analyze potential lessons learned from
attrition. Finally, explain how you might design a study to
gather data about the effectiveness of these parenting classes.
Use the following questions to focus your thinking:
Would you recommend a pre-experimental, experimental, or
quasi-experimental design?
Would the study involve measurement over time?
Would there be a control group?
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?
Please use the resources to support your answer.
Please note that each discussion has to have its own 1 page

  • 1. Week 5 Once you have a fairly narrow research question and have conducted a thorough literature review, the next step is to turn your attention to the research design. The research design is simply a plan for how you will conduct your research, as it informs each step of the research process. In addition to research design, you are introduced to the concepts of internal and external validity and generalizability. During the latter half of the week, you focus on a particular instrument of measurement: the pretest and posttest. Capturing information from research study participants both before and after a particular event can yield priceless data. Learning Objectives Students will: Classify types of group research designs Analyze possible study limitations Analyze relative internal and external validity Analyze generalizability Analyze a pretest–posttest in a case study Evaluate research designs to assess program effectiveness Analyze potential lessons learned from attrition

  • 5. Discussion 1 One page paper There are several different types of research designs. Each design is intended to respond to a particular type of research question. The type of research design depends on the type of research questions asked. For this Discussion, select one of the articles from the reading list and consider several classifications of group research designs. Post your response to the following: Describe which groups are compared in the research. Then, classify the research design as follows: By explaining whether the study is pre-experimental (cross- sectional, one-shot case study, and longitudinal), experimental (control group with pretest and posttest, posttest only, or four- group design), or quasi-experimental (comparing one group to itself at different times or comparing two different groups) By indicating what the researchers report about limitations of the study By explaining concerns you have regarding internal validity and the ability of the study to draw conclusions about causality By explaining any concerns you have about the generalizability of the study (external validity) and what aspect of the research design might limit generalizability

Week 5 Group Research Designs for Social Work Knowledge Development and Practice Evaluation Discussion 2 one page paper Discussion 2: Pretests/Posttests and Attrition This week's video introduces you to the Hernandez family. Juan and Elena Hernandez are mandated to attend parenting classes. As part of the parenting classes, they are required to participate in both a pretest (taken before classes begin) and a posttest (taken after classes end). Pretests and posttests can yield very useful information. They can measure the learning that has or has not taken place as a result of the education being provided. For this Discussion, imagine what kinds of questions would be on a pretest and posttest for this particular study sample (the parents who are taking parenting classes). Post
  • 7. your explanation of what you think the social workers wanted to know when they designed the pre/posttest for evaluating the parenting classes. Be sure to address the concept of attrition and whether or not you believe they took that into account. Be sure to explain why. Then, analyze potential lessons learned from attrition. Finally, explain how you might design a study to gather data about the effectiveness of these parenting classes. Use the following questions to focus your thinking: Would you recommend a pre-experimental, experimental, or quasi-experimental design? Would the study involve measurement over time? Would there be a control group? 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?
