Codes and Frequencies
For sample adults age 18+ who lost interest in pleasurable activities for 2+ weeks during the past 12 months (DEPLIFUN), DEPLIDAYAMT reports responses to a question about the duration of respondents' symptoms related to major depression with anhedonia. Before reading this question, interviewers instructed respondents, "For the next few questions, please think of the two week period during the past 12 months when you had the most complete loss of interest in things." Respondents were then asked, "During that two week period, did the loss of interest usually last all day long, most of the day, about half the day, or less than half the day?"
Related Variables for Screening Major Depression
Respondents only received the question associated with DEPLIDAYAMT if they failed to pass a series of screening questions on major depression with dysphoric mood (feeling sad, blue, or depressed) (DEP2WKEV, DEPDAYAMT, DEPHOWOFT).
Respondents did not pass these screening questions if they:
- Did not feel sad, blue, or depressed for 2+ weeks in a row (a "No" in DEP2WKEV); or
- Volunteered in DEP2WKEV that they were on medication/anti-depressants; or
- Reported that their feeling sad, blue, or depressed lasted "Less than half of the day" in DEPDAYAMT; or
- Reported that their feeling sad, blue, or depressed lasted "Less often" in DEPHOWOFT; or
- Had an unknown response in DEP2WKEV, DEPDAYAMT, or DEPHOWOFT.
For more information on the dysphoric mood questions, see DEP2WKEV.
DEPLIDAYAMT was part of a series of mental health questions constituting the NHIS version of the Composite International Diagnostic Interview - Short Form (CIDI-SF) screening scale for major depression. More specifically, DEPLIDAYAMT was part of a group of questions on major depression with anhedonia (loss of interest in pleasurable activities).
According to the Field Representative's Manual for 1999, this set of questions was included "to determine if the Sample Adult has had or still has a loss of interest in things, indicating undiagnosed depression, in the past 12 months and, if so, how it affected them physically and emotionally, how long it has affected them, how they dealt with these problems, and how much these problems interfered with their life or activities."
DEPLIDAYAMT was the second of three screening questions used to determine whether individuals received a series of questions about the symptoms of anhedonia, along with supplemental questions about the duration and consequences of anhedonia.
In the NHIS instrument, respondents who answered "All day long," "Most of the day," or "About half of the day" to the question associated with DEPLIDAYAMT were asked a third screening question for anhedonia:
- During those two weeks, did you feel this way every day, almost every day, or less often? (DEPLIHOWOFT)
Respondents who passed the first two screening questions (DEPLIFUN, DEPLIDAYAMT) and who answered "Every day" or "Almost every day" in DEPLIHOWOFT received a series of symptom questions on major depression with anhedonia. Respondents who did not pass all three of the anhedonia screening questions received no further questions on major depression related to anhedonic symptoms.
Respondents who reported experiencing at least one symptom of major depression with anhedonia were also asked supplemental questions about the length of time they lost interest in pleasurable activities and about the effects of these symptoms on their lives.
The anhedonia questions contained in the NHIS version of the CIDI-SF can be used to calculate the probability of psychiatric caseness for major depression with anhedonia.
For more information on all the variables associated with the NHIS CIDI-SF screening scale for major depression, and for instructions on how to calculate scores for major depression with anhedonia, see DEPLIFUN.
This variable only occurs in 1999.
In 1999, a similar question, "During that time did the feelings of being sad, blue, or depressed usually last all day long, most of the day, about half of the day or less than half of the day?" (DEPDAYAMT), was asked of sample adults age 18+ who passed the first screening question for major depression with dysphoric mood (DEP2WKEV).
- 1999: Sample adults age 18+ who either did NOT feel sad/blue/depressed all day long, most of the day, or about half of the day, every day or almost every day, for 2+ weeks during past 12 months, OR were on medication/anti-depressants OR whose feelings of being sad/blue/depressed, or the duration of these feelings, or the frequency of these feelings is unknown AND lost interest in activities for 2+ weeks during the past 12 months.
