DEPWTAMT is a variable with three columns and no implied decimal place.
000 = NIU (Not in Universe)
997 = Unknown-refused
998 = Unknown-not ascertained
999 = Unknown-don't know
For sample adults age 18+ who (1) felt sad, blue, or depressed (DEP2WKEV), (2) for all day long, most of the day, or about half of the day (DEPDAYAMT), (3) for every day or almost every day (DEPHOWOFT), for 2+ weeks during the past 12 months and (4) reported that their weight changed during this period (DEPWT), DEPWTAMT reports responses to the question, "About how much did [you gain/you lose/your weight change]?" The reference period for DEPWTAMT was the two-week period during the past 12 months when the feelings of being sad, blue, or depressed were the worst.
Respondents who did not know the amount of weight change in DEPWTAMT (IPUMS NHIS code 9) were asked, "Did your weight change by 10 pounds or more?" (DEPWT10).
Related Variables for Scoring Major Depression
DEPWTAMT 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, DEPWTAMT was part of a group of questions on major depression with dysphoric mood (feeling sad, blue, or depressed).
According to the Field Representative's Manual for 1999, this set of questions was included "to determine if the Sample Adult has been or still is depressed 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 (DEP2WKEV, DEPDAYAMT, DEPHOWOFT), respondents received an additional series of questions on symptoms of major depression with dysphoric mood. DEPWT, DEPWTAMT, and DEPWT10 were part of this series of symptom questions.
The other questions dealing with symptoms of depression with dysphoric mood related to the following:
- Lost interest in most things during 2+ weeks sad/blue/depressed, past 12 months (DEPLI)
- Felt more lethargic during 2+ weeks sad/blue/depressed, past 12 months (DEPLETH)
- Had trouble sleeping during 2+ weeks sad/blue/depressed, past 12 months (DEPINSOM)
- (For respondents who had trouble sleeping) How often had trouble sleeping during 2+ weeks sad/blue/depressed, past 12 months (DEPINSOMOFT)
- Had trouble concentrating during 2+ weeks sad/blue/depressed, past 12 months (DEPCONCEN)
- Felt worthless/no good during 2+ weeks sad/blue/depressed, past 12 months (DEPNOGOOD)
- Thought about death during 2+ weeks sad/blue/depressed, past 12 months (DEPSUICID)
Respondents who reported that their weight changed by 10+ pounds (a "Yes" response in DEPWT and either a report of 10+ pounds in DEPWTAMT or a "Yes" response in DEPWT10), or who gave affirmative answers to other symptom questions, were also asked supplemental questions about the length of time they felt sad, blue, or depressed and about the effects of these symptoms on their lives (see DEPWKNO).
Respondents who reported that their weight changed by 10+ pounds (according to DEPWT and DEPWTAMT or DEPWT10) received one point in the scoring system for major depression with dysphoric mood (a scale running from 0 to 7, with 3 or more classified as a probable case of major depression with dysphoric mood).
Additional points were given for affirmative responses to other symptom questions; see DEP2WKEV for details on the other CIDI-SF variables and the calculation of major depression scores.
This variable only occurs in 1999.
In 1999, a similar question, "About how much did [you gain/you lose/your weight change]?" (DEPLIWTAMT), was asked of sample adults age 18+ who passed the screening questions for major depression with anhedonia (loss of interest in pleasurable activities) (DEPLIFUN, DEPLIDAYAMT, DEPLIHOWOFT) and who reported that their weight changed during the two-week period they lost interest in pleasurable activities (DEPLIWT). Only persons who were skipped out of the survey section related to dysphoric mood (and who thus did not answer the question for DEPWTAMT) received the question associated with DEPLIWTAMT.
