The Center for
Epidemiologic Studies Depression Scale (CES-D Scale)

In the Assignment Instructions folder, there is an SPSS data file
that will be the basis for your analysis. The data included are fictional and
were created solely for this assignment.

The Center for
Epidemiologic Studies Depression Scale (CES-D scale) is often utilized to
measure depressive symptomology (Radloff, 1977). It is a self-assessment that
is completed by the individual. The CES-D contains 20-items rated on a 4-point
scale (0 = Rarely or None of the Time
to 3 = Most or All of the Time). The
phrase “Within the past week did you…” prefaces the questions in order to
emphasize 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 of
27 is considered a more useful cut-off (Zich, et al., 1990). The full scale can
be 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). Several
studies have validated four subscales across a variety of subgroups (i.e.,
depressive affect, well-being, somatic, and interpersonal) (Gliem & Gliem,
2003).

Reliability and Subtest
Scoring

You
will continue the analysis of the CES-D data by learning to score the survey
and create subtest scores. Note: we are creating our own norms on this survey for
Friberg University students so there are no scores for comparison.

According
to 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.  Reverse
code 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.  Compute
the total CES-D score.

3.  Compute
the four subscale scores. (Note: Be
careful when interpreting “well-being.”)

4.  Calculate
Cronbach’s alpha for the overall scale and each subscale.

5.  Create
a single table to show the appropriate measures of central tendency and dispersion
for all of the variables (total, depressive affect, well-being, somatic, and
interpersonal).

6.  Create
the appropriate graphs to show the distribution of scores for each subscale.

7.  Write
a summary paragraph explaining the outcome: Overall, scores ranged from X to XX
(M = X, SD = X.X), indicating…. Subscale scores revealed…. Be sure to include
means, standard deviations, Cronbach’s alphas, and interpretations of the data.
