Question 4

RESEARCH STUDY 5.4
Dr. Li is interested in creating a measurement of religiosity. According to the dictionary, religiosity is "the quality of being religious; piety; devoutness." He creates a measure comprising 10 statements. People respond to each statement using the following scale (1 = strongly disagree, 3 = neither agree nor disagree, 5 = strongly agree). Some of the statements are below.
Statement 1: "I believe in a religion."
Statement 2: "Part of who I am stems from my religious beliefs."
Statement 3: "I believe that religion is unnecessary."
-Refer to Research Study 5.4 above to answer the following question.
Provide a suggestion for how Dr.Li could establish the predictive validity of his measure and a suggestion for how he could establish the concurrent validity of his measure.

Accepted Answer

Concurrent validity could be established

Question 5

RESEARCH STUDY 5.2
Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions and it takes 20 minutes to complete.
-Refer to Research Study 5.2 above to answer the following question. Dr.Sheffield decides to test the predictive validity of his measure.Dr.Sheffield gives his measure to a group of people that includes suspected problem gamblers and non-gamblers.Which of the following options below does he need to do in addition to get evidence for predictive validity?

Accepted Answer

A)  Give the measure to a group of people attending Gamblers Anonymous meetings 
B)  Two months later, ask the same group of people to report how many times they have gambled recently 
C)  Ask the participants to give their opinion on whether the measure is valid 
D)  Give a measure of alcohol addiction to the same group of clients 
E)  None of the above

Question 10

RESEARCH STUDY 5.1
Dr. Valencia is considering conducting a study examining whether narcissistic people have poorer social interactions than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Mayo scale. Question 1 reads, "I tend not to think about other people as much as myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special."
-Refer to Research Study 5.1 above to answer the following question. Before using the measure in her study,Dr.Valencia gives the measure to a group of students on Tuesday.She gives the measure to them again on Thursday.She then compares the scores between the two days.This is a test of which of the following?
