SPSSAssignment Part 2 Instructions
The Center forEpidemiologic Studies Depression Scale (CES-D Scale)
In the Assignment Instructions folder, there is an SPSS data filethat will be the basis for your analysis. The data included are fictional andwere created solely for this assignment.
The Center forEpidemiologic Studies Depression Scale (CES-D scale) is often utilized tomeasure depressive symptomology (Radloff, 1977). It is a self-assessment thatis completed by the individual. The CES-D contains 20-items rated on a 4-pointscale (0 = Rarely or None of the Timeto 3 = Most or All of the Time). Thephrase “Within the past week did you…” prefaces the questions in order toemphasize recent depressive mood. Scores are summed and can range from 0 to 60.Traditionally, individuals with scores over 16 are identified as “depressed”(Weissman, et al., 1977), though due to high false positive rates, a score of27 is considered a more useful cut-off (Zich, et al., 1990). The full scale canbe accessed at: http://www.chcr.brown.edu/pcoc/cesdscale.pdf. Items 4, 8,12, and 16 are reversed to avoid “yay-saying” or “nay saying” (Radloff, 1977). Severalstudies have validated four subscales across a variety of subgroups (i.e.,depressive affect, well-being, somatic, and interpersonal) (Gliem & Gliem,2003).
Reliability and SubtestScoring
Youwill continue the analysis of the CES-D data by learning to score the surveyand create subtest scores. Note: we are creating our own norms on this survey forFriberg University students so there are no scores for comparison.
Accordingto Knight, Williams, McGee, and Olaman (1997) and many others (e.g., Gliem& Gliem, 2003), the following subscales can be calculated:
CES-D Subscales
DA = Depressive Affect
W = Well-being
S = Somatic
I = Interpersonal
1. S
2. S
3. DA
4. W
5. S
6. DA
7. S
8. W
9. DA
10. DA
11. S
12. W
13. S
14. DA
15. I
16. W
17. DA
18. DA
19. I
20. S
1. Reversecode the appropriate items (4, 8, 12, and 16) for calculating the total score(0 becomes 3, 1 becomes 2, 2 becomes 1, and 3 becomes 0).
2. Computethe total CES-D score.
3. Computethe four subscale scores. (Note: Becareful when interpreting “well-being.”)
4. CalculateCronbach’s alpha for the overall scale and each subscale.
5. Createa single table to show the appropriate measures of central tendency and dispersionfor all of the variables (total, depressive affect, well-being, somatic, andinterpersonal).
6. Createthe appropriate graphs to show the distribution of scores for each subscale.
7. Writea summary paragraph explaining the outcome: Overall, scores ranged from X to XX(M = X, SD = X.X), indicating…. Subscale scores revealed…. Be sure to includemeans, standard deviations, Cronbach’s alphas, and interpretations of the data.
This assignment is due by 11:59 p.m.(ET) on Monday of Module/Week 3.
