Dr. Reynolds developed a treatment for social anxiety disorder. In his initial test of the treatment, he found it was effective in decreasing social anxiety symptoms in adults who only had social anxiety. Because Dr. Reynolds knows people who have social anxiety disorder also often are depressed, he designs a second study to test whether his treatment decreases social anxiety symptoms in two different groups of people - those who have social anxiety disorder only and those who have both social anxiety disorder and depression. This second study would be which of the following?
a- direct replication
b- meta-analysis replication
c- conceptual replication
d- replication-plus-extension

Replication-plus-extension study is a type of replication study which involves researchers replicating their original study but adding more variables or conditions that try to answer additional questions about the subject.

In this case, Dr Reynold has an effective treatment in decreasing social anxiety symptoms in adults who only had social anxiety but then decided to design a second study which adds variables such as those who have social anxiety disorder only and those who have both social anxiety disorder and depression.

Answer:

d) replication-plus-extension

Explanation:

replication-plus-extension. a study in which researchers replicate their original study but add variables to test additional questions/participant variable. These extraneous variables are related to individual characteristics of each participant that may impact how he or she responds.

Since the first treatment was effective in decreasing social anxiety symptoms in adults who only had social anxiety

Also Dr. Reynolds knows people who have social anxiety disorder also often are depressed so he designed the second study to test the additional variable. hence D
