Description
For sample adults age 18+ who (1) lost interest in pleasurable activities (DEPLIFUN), (2) for all day long, most of the day, or about half the day (DEPLIDAYAMT), (3) for every day or almost every day (DEPLIHOWOFT), for 2+ weeks during the past 12 months, DEPLIINTFERE reports responses to the question, "How much did these problems interfere with your life or activities -- a lot, some, a little or not at all?"
Related Variables for Screening Major Depression
Respondents only received the question associated with DEPLIINTFERE if they failed to pass a series of screening questions on major depression with dysphoric mood (feeling sad, blue, or depressed) (DEP2WKEV, DEPDAYAMT, DEPHOWOFT).
[show more]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.
DEPLIINTFERE 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, DEPLIINTFERE was part of a group of questions on major depression with anhedonia (loss of interest in pleasurable activities).
[show more]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."
After passing three screening questions (DEPLIFUN, DEPLIDAYAMT, DEPLIHOWOFT), respondents received an additional series of questions addressing symptoms of depression related to anhedonia. DEPLIINTFERE is part of a series of supplemental questions asked of respondents who experienced at least one symptom of depression with anhedonia.
[show more]To be asked the question associated with DEPLIINTFERE, respondents had to report experiencing one of the following symptoms:
- Felt more lethargic than usual ("Yes" in DEPLILETH)
- Weight changed 10+ pounds ("Gain," "Lose," or "Volunteered 'both gained and lost weight'" in DEPLIWT and "10+" in DEPLIWTAMT or "Yes" in DEPLIWT10)
- Had trouble sleeping every night or nearly every night ("Yes" in DEPLINSOM and "Every night" or "Nearly every night" in DEPLINSOMOFT)
- Had trouble concentrating ("Yes" in DEPLICONCEN)
- Felt worthless or no good ("Yes" in DEPLINOGOOD)
- Thought about death ("Yes" in DEPLISUICID)
The reference period for these symptoms was the two-week period during the past 12 months when respondents had the most complete loss of interest in things. Respondents who reported experiencing one or more of these symptoms were asked the series of supplemental questions that included DEPLIINTFERE (Amount loss of interest in activities 2+ weeks during the past 12 months interfered with life). Before reading the first supplemental question, the interviewer stated, "To review, you had two weeks in a row during the past 12 months when you lost interest in most things and also had some other feelings or problems like:" and read up to three of the symptoms the respondent reported experiencing.
In addition to DEPLIINTFERE, supplemental questions were asked about the following:
- Total number of weeks lost interest in activities during past 12 months (DEPLIWKNO)
- Most recent month lost interest in activities 2+ weeks (DEPLIWHENMO)
- Most recent year, 1998-2000, lost interest in activities 2+ weeks (DEPLIWHENYR)
- Told doctor about losing interest in activities 2+ weeks during the past 12 months (DEPLITOLDDR)
- Told health professional about losing interest in activities 2+ weeks during the past 12 months (DEPLITOLDHP)
- Used medication/drugs/alcohol to cope with loss of interest in activities (DEPLIDRUGALC)
Although a part of the NHIS CIDI-SF screening scale for major depression, DEPLIINTFERE and the other supplemental questions listed above were not used in calculating major depression scores, but rather provide information about how long respondents were affected and the impact of symptoms on their lives.
[show more]In contrast, answers to the symptom questions can be used to calculate the probability of psychiatric caseness for major depression with anhedonia. For more information on the other CIDI-SF variables and for instructions on how to calculate scores for major depression with anhedonia, see DEPLIFUN.
Comparability
This variable only occurs in 1999.
In 1999, a similar question, "How much did these problems interfere with your life or activities -- a lot, some, a little or not at all?" (DEPINTFERE), was asked of sample adults age 18+ who passed the screening questions for major depression with dysphoric mood (feeling sad, blue, or depressed) (DEP2WKEV, DEPDAYAMT, DEPHOWOFT) and who reported experiencing at least one symptom of major depression with dysphoric mood. Respondents who received the questions associated with DEPINTFERE were not asked about symptoms of depression related to anhedonia, and therefore did not answer the question for DEPLIINTFERE.
