DEPANHCDC is a one-column variable.
0 = No symptoms of anhedonic depression
1 = One symptom of anhedonic depression
2 = Two symptoms of anhedonic depression
3 = Three symptoms of anhedonic depression or took antidepressants
4 = Four symptoms of anhedonic depression
5 = Five symptoms of anhedonic depression
6 = Six symptoms of anhedonic depression
7 = Seven symptoms of anhedonic depression
9 = NIU
Description
For sample adults, DEPANHCDC reports results for a summary measure that allows researchers to calculate the likelihood a respondent met the diagnostic criteria (i.e., psychiatric caseness) for the mental disorder major depression with anhedonia (i.e., loss of interest in pleasurable activities). DEPANHCDC is an IPUMS NHIS-created variable that summarizes responses given to the series of questions making up the NHIS version of the Composite International Diagnostic Interview - Short Form (CIDI-SF) for major depression with anhedonia. Apart from the value of 9 for persons not asked these questions, DEPANHCDC has a value ranging from 0 to 7, with a score of 3 or more indicating a probable case for major depression with anhedonia.
Related Variables for Scoring Major Variables
As explained in greater detail in the variable description for DEPLIFUN, the NHIS version of the CIDI-SF instrument for major depression with anhedonia began with a series of three screening questions that determined whether respondents qualified for a second round of questioning on symptoms associated with anhedonia. Those who did not pass the first screening question received a score of 0 in DEPANHCDC. Those who passed the first screening question but not the second two received a score of 1 in DEPANHCDC. Those who reported taking anti-depressants during the filter questions were not asked about symptoms of depression but were given a value of 3 in DEPANHCDC. Those who passed all three screening questions on anhedonia received one point for each of the 6 symptoms of depression they endorsed. Summing the number of endorsed items relating to symptoms of depression and adding one point for passing the first screening question results in a score ranging from 1 to 7. As noted, those who did not pass the first screening question received a score of 0.
Two versions of the CIDI - SF for major depression with anhedonia were developed, one for the NHIS and one for the World Health Organization (WHO). The two versions differed in their skip patterns and thus their scoring system. As noted, DEPANHCDC is based on the NHIS version of the CIDI - SF for major depression with anhedonia; for a synonymous summary measure for the WHO version, see DEPANHWHO. For further information about the two versions of the CIDI - SF for major depression with anhedonia and the scoring of each, see DEPLIFUN.
Along with the inquiry into major depression with anhedonia, the NHIS made use of a CIDI - SF instrument to evaluate major depression with dysphoric mood (feeling sad, blue, or depressed) (see DEP2WKEV). There are, again, both an NHIS and a WHO version of this instrument, and a complementary summary measure of psychiatric caseness for each (see DEPDYSCDC and DEPDYSWHO).
