Question

Answers are one of the four for each one.

Identify the type of threats being described in the following table. Scenario Threat Micah has an intervention designed to encourage young homosexual men to get tested for HIV and other sexually transmitted infections. In the midst of his intervention, a well-known actor discloses that he is HIV positive, and he encourages everyone to be tested and to know their own status and the status of others with whom they are intimate. History Harry is conducting research that includes using physiological measures like EEGs. His research assistant is uncomfortable doing the setup for EEGs, so with his many years of experience, Harry does all of the setups for the first phase of the study but makes his research assistant do the setups for the second phase. Maturation Regressiorn Rory has developed an intervention for individuals with obsessive-compulsive disorder. Before he starts his intervention, he administers a test designed to measure the severity of obsessions and compulsions, and the group has an extremely high average score-well above the mean score that would be expected for individuals with obsessive-compulsive disorder. Following the intervention, there is a reduction in the groups' score on the test Shawna has developed an intervention to help young children who are struggling with quantitative skills. At the time of her initial testing, she realizes that the children are learning but that they are learning more slowly than are other students.

Explanation / Answer

1. Maturation. The revelation of HiV by the famous actor would lead to a change in the mentality and behavior of the homosexual participants psychologically. This is the common phenomenon of maturation wherein the action are influenced by a factor which imaoct the results of the study.

2. Instrumentation. This phenomenon would be instrumentation as the operationalization of an instrument leads to a discrepancy in the study ad the orientation of the instrument is different in the study setting. As is the case with Harry and His research assistant.

3. Regression. Roy has selected people who are above the avegarge threshold, that is, with extreme scores and extreme scores vitiate the results of a study as after pretest amd post test the results tend to veer towards the mean easily.

4. History. Within this when there are external factors looming, which threaten to influence the study and are not within the control of the investigator, then the results are impacted. For instance, the initial pahse of studying the skills is slacking, but the passage of time could impact the study if the children practice in their free time, then the validity of the intervention cannot be tested.
