Spss Laboratory

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.

2. 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.

3. 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).

4. 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.
