You give a survey on attitudes toward violence. You find that even without doing any intervention, students are less supportive of violence to solve problems the second time they take the survey than they were the first time. This is an example of

A social worker tests whether her school high school drop out program is effective. She gives her program and then measures how many students drop out of high school. This is an example of what type of study design?
What is one group post test only

You use a one group pre-post test design to evaluate bullying awareness created by a bully prevention program. At the pre-test you give a survey to a group of high school students they are sitting in a noisy cafeteria. At the post-test you give the survey in a quiet library. Name the threat to internal validity

The reason random assignment is so powerful is because it makes your program and comparison groups
What is equally susceptible to the threats to internal validity

O X O is an example of what type of design?
What is 1 group pre and post test design

In the Single Subject Experiment, the "B" or "C" or other letters stand for
What is the intervention, program, or independent variable

You have a 2-group pre and post test quasi experiment to test a suicide prevention program. You collect data in the Fall from your control group. In the Spring you collect data to evaluate your program. Between the Fall and Spring a well known, well liked student commits suicide. This threat to internal validity is called
What is history

You use random assignment when assigning participants to your control and experimental groups but you find that your groups differ on an important variable at the start of the study, i.e., your groups are not equivalent, what strategy can you use to minimize the selection bias (difference)?
What is matching
300
Name one reason why a two group pre and post test design is better than a one group pre and post test design because
By adding a second group you can control for the effects of history and testing

When no comparison group is used to evaluate a program's effectiveness (one group pre and post test design), name 3 threats to internal validity that are not controlled.
What is selection bias, testing, history, or maturation

TRUE OR FALSE In a true experiment you never use a comparison group
What is FALSE

Suppose a child welfare agency keeps good records of the rate of out of home placement in cases of child abuse/neglect starting in 2000. In 2005, a new policy is created to improve family preservation services. The agency continues to keep records in the same way until 2010. What are the IV and DV?
IV policy to improve family preservation services DV rate of out of home placements

You can infer cause-effect in an ABABA study design if....
Every time B is introduced A changes and every time B is taken away A changes again, back to baseline

You conduct a conflict resolution program during the school year. Before you begin your program you select children, who are identified by teachers to have trouble getting along with peers. You administer a pre test and post test to this group. You also collect data from a randomly chosen group of students at the same times as those in your program to serve as your control group. Name two threats that present the greatest problem to your evaluation study.
What is selection bias AND diffusion of treatment

Suppose you are evaluating the stability of attentional focus in a sample of first graders. You administer your pre-test at the start of the school day and your post-test at the school day. By the end of the day, the students are tired, hungry and cranky. 1) Name which threat to internal validity is described AND 2) Name one thing you can do to improve this study so stability of attentional focus can be evaluated
What is 1) Maturation 2) Administer the attentional focus test at the same time of day at the pre and post test OR give students a snack or rest period BEFORE giving the attentional focus pre test and post test.

Suppose a child welfare agency keeps good records of the rate of out of home placement in cases of child abuse/neglect starting in 2000. In 2005, a new policy is created to improve family preservation services. The agency continues to keep records in the same way until 2010. In 2011, the agency wants to know if the policy decreased out of home placements. What conclusions could the agency make?
Because of the repeated assessments, the agency could look at trends before and after the policy change. The more observations someone has over a long time period, the more confidence one has in the relationship between the independent and dependent variable.
