Analog Studies and Quasi-Experiments

Question 1

Analog Study

Answer 1

• Applys the results of a study of undiagnosed individuals to understand psychopathology

Question 2

Quasi Experiments

Answer 2

• Involve some form of manipulation, such as variations in the information provided prior to undertaking a task

Question 3

Quasi Experiments with Diagnosed vs. Undiagnosed Groups

Answer 3

• No random assignment to diagnosed vs. undiagnosed groups
• People come to the study with a history of the variable
• Anything that correlates with this variable could be a ‘third variable’

Question 4

Strengths of Using Analog Groups

Answer 4

• Non-disordered participants are easier to recruit
• Less tricky ethical issues

Question 5

Weakness of Using Analog Groups

Answer 5

• Seen as less instructive
• Question of how representative a high-individual difference person is of a diagnosed person

Question 6

Strengths of Quasi-Experiments with Diagnosed vs. Undiagnosed Groups

Answer 6

• There is less inference needed

Question 7

Weaknesses of Quasi-Experiments

Answer 7

• Need to be careful that the effects of experimentation do not elevate the symptoms of diagnosed people
• More difficult for researchers to control nature or severity of symptoms
• Tricky ethical issues around withholding treatment
