Use SPSS to compute the coefficient alpha (α) for the revised UCLA Loneliness Scale and for the University of Winnipeg Loneliness Scale. See the SPSS
directions below. Print the coefficient alphas onto a single page of output. Circle and clearly label the coefficient alpha (α) for each scale.
- What is coefficient alpha (α) for the revised UCLA Loneliness Scale? What is coefficient alpha (α) for the U of W Loneliness Scale? (Your answers should be
in the form of a complete sentence.
- Most investigators would be satisfied with an alpha of 0.7 or higher for an estimate of internal-consistency reliability. Does the U of W Loneliness Scale
pass this criterion? How about the revised UCLA Loneliness Scale? (Your answers should be in the form of a complete sentence; ‘yes/no’ is not a satisfactory
answer).
- Which scale has the higher reliability estimate? If one scale has a higher alpha than the other, is it necessarily a better measure of the loneliness
construct? Please explain your answer.
