DIAGNOSTIC INTERVIEW SCHEDULE (DIS) The mental health component of NHANES III included the depression and mania modules from the Diagnostic Interview Schedule (DIS) originally developed for the National Institute of Mental Health (NIMH) Epidemiologic Catchment Area (ECA) program. Trained interviewers administered the NHANES III DIS questions in the MEC, using automated data entry, as part of the MEC Youth Questionnaire for examinees 15-16 years of age and as part of the MEC Adult Questionnaire for examinees 17-39 years of age. The data from the DIS permit diagnoses based on the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM- III). The final MEC examination weight (MTPFEX6) should be used for analysis of the questionnaires and measurements administered in the MEC, as well as for a combined analysis of measurements from the MEC examinations and associated medical history questions from the household interview. The household questionnaire data files include information on survey design and basic demographic variables which may be linked to the examination data file by using the unique survey participant identifier SEQN. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The DIS is a complicated questionnaire with a number of parallel series of questions and many skip instructions. The notes below describe these question series and skip patterns, and analysts are instructed to carefully read these notes in their entirety in order to facilitate analysis of this data. The Plan and Operation of the Third National Health and Nutrition Examination Survey, 1988-94, page 362, (NCHS, 1994; U.S. DHHS, 1996b) contains a flow chart of the probe questions and skips from the DIS. All variable names in the DIS portion of the MEC interviews start with the prefix MQP. The M indicates that it came from the MEC interview, the Q indicates that the data transcend the boundaries of separate adult (A) and youth (Y) interviews (sample persons ranged from ages 15-39) and the P indicates the data came from the primary interview. Any sample person who was age 15 to 39 was eligible to receive this section of the adult or youth MEC questionnaire. A sample person who was not eligible to receive this section of the questionnaire will have all blanks in this section. Note that selected questions may be blank in the DIS section if the question was not applicable for the sample person to answer because of answers they had given to other questions. Also note that many of the questions have combined the "Don't know" and "No" category into a single response and this combination will vary per question in the DIS section. Approximately 3.7% (322/8773) of the NHANES III sample did not have valid depression and mania sections of the questionnaire, with an additional 18 or 0.2% missing all or part of one section or the other. The major reasons for these missing data are that respondents: 1) ran out of time, 2) felt the material was too sensitive, usually because they were using an interpreter, 3) had comprehension problems due to cognitive impairment, 4) primary language was not English or Spanish, or 5) refused to answer or were not asked critical questions. All of the questions for these sample persons were coded "Blank but applicable."

There were 41 adults and 32 youth where this change was made in the study. Most Hispanic youth spoke English fluently enough that a Spanish translation was not necessary, therefore, no computerized version of the youth interview was available in Spanish. It was only given on hard copy. MQPDLANG was set to 4, Spanish Youth, only if the variable DMAETHNR was greater than or equal to 3 and MQPLANG was equal to 3, and the examination was given on hard copy (MQPHCFLG=1) or a specific comment was made that indicates the interview was given in Spanish. MQPDPFLG, MQPMNFLG: Depression and mania completeness flags When a code of "1" is given to the depression (MQPDPFLG) or mania (MQPMNFLG) completeness flag, the respondent only answered the lifetime symptom questions (16 for depression and 9 for mania) and any appropriate probe questions. It was then determined in MQPG21, a check item, that there were not enough positive symptom groups to continue asking questions (MQPG21=3 or MQPG50=3 for depression and mania, respectively). The diagnosis of major depressive episode (MQPDEP) or manic episode (MQPMANIA), respectively, is set to "No." When a code of "2" is given to the depression (MQPDPFLG) or mania (MQPMNFLG) completeness flag, the respondent answered not only the lifetime symptom questions (16 for depression and 9 for mania) and any appropriate probe questions but also one or more of the questions concerning clustering of the positive symptom groups. These sample persons can skip out of the section at several different points, but they never answer questions past MQPG26 or MQPG55, respectively, and they cannot have a positive diagnosis for major depressive episode (MQPDEP) or manic episode (MQPMANIA). The diagnosis of major depressive episode or manic episode, respectively, is set to "No." When a code of "3" is given to the depression (MQPDPFLG) or mania (MQPMNFLG) completeness flag, the respondent answered not only the lifetime symptom questions (16 for depression and 9 for mania) and any appropriate probe questions but also all the questions concerning clustering of the positive symptom groups and the worst episode. These sample persons should have answers to all questions in their respective sections and have the chance for a positive diagnosis for major depressive episode (MQPDEP) or manic episode (MQPMANIA). The diagnosis of major depressive episode ranges from 1-5 and the diagnosis of manic episode ranges from 1-3. When a code of "4" is given, the lifetime symptoms were completed and the sample person met criteria to continue answering questions (MQPG21=1 or 2), but the remaining section of questions needed to make a diagnosis were not ascertained (blank, but applicable) or were all answered "don't know." This is not the same as MQPG21=3 or MQPDPFLG=1 where sample persons only answered the lifetime symptom questions because they did not have enough positive symptoms to qualify to answer the remaining questions. When a code of "5" is given, the depression and/or mania section should have been given, but was not, so all fields are filled with 8's (blank but applicable). Lastly, a blank in this field indicates the sample person was not in the acceptable age range and was not eligible for the depression or mania questions. In short, the flags divide the data into five groups: 1. Lifetime symptoms answered, insufficient number positive to ask clustering questions 2. Sufficient lifetime symptoms present but do not cluster in spells of sufficient duration 3. Sufficient lifetime symptoms present and cluster in spells of sufficient duration, and may or may not meet criteria for positive diagnosis 4. Sufficient lifetime symptoms present but no information available if cluster in spells of sufficient duration - missing diagnosis 5. No information available, but should have been collected - missing diagnosis Blank values appear where the DIS not applicable. MQPHCFLG: Hard copy flag Although in almost all circumstances the DIS section of the interview was given using the computerized version, there were certain situations where a paper copy was used. This would occur only when there was a computer failure or for youth who required a Spanish version. These interviews are considered valid, but responses to probe questions were not recorded, and are therefore set to 8's (blank but applicable). MQPG0501-MQPG1301, MQPG05L-MQPG12L, MQPG1501-MQPG1601, MQPG14L-MQPG20L: Lifetime symptoms of depression The questionnaire inquires whether a symptom has occurred at any time in life (G5-G20). Each of these DIS symptom questions can take a value of "1-4." The value "2" means the respondent said "No" or "Don't know." If the respondent said "Yes," additional "probe" questions were asked. First, the respondent was asked if they told a doctor about the symptom. The answer to this probe question is included after each respective lifetime symptom. When the interview was given on hard copy (i.e., not by computer - See MQPHCFLG, a flag for hard copy), no probe questions were recorded so the probe questions are filled with 8's (blank but applicable). The respondent was then asked if the symptom was always due to a physical illness or injury (this included pregnancy). If the respondent said "Yes," then a "4" was coded. If the respondent said "No," then he/she was next asked whether the symptom always occurred when he/she used medicine, alcohol, or drugs. If the respondent said "Yes," then a "3" was coded. If the respondent said "No," then a "1" was coded. A value of "1" indicates that the possibility of this being a symptom of a mental disorder cannot be ruled out. Additional probes were asked for G13. (See notes for MQPG1302-MQPG1304.) As a word of caution, in the Spanish version of question G8, "Have you ever had a period of two weeks or more when you had trouble falling asleep, staying asleep, or with waking up too early?," the phrase used for "falling asleep" really meant "staying asleep" rather than what was intended. Still another phrase was used for the part of the question "staying asleep." Consequently, "staying asleep" was well covered and "falling asleep" was not. There is no way to tell to what extent this affected the number of positive responses. MQPDGP1L-MQPDGP8L: Summary questions The lifetime depressive symptom questions (G5-G20) are arranged in eight groups, each of which approximates one of the diagnostic criteria in Section B of the definition of a major depressive episode from the American Psychiatric Association's Diagnostic and Statistical Manual, Third Edition (DSM-III). MQPDGP1L- MQPDGP8L are the eight summary variables which indicate the number of positive (1's) lifetime symptoms in each of the respective groups. MQPG13L, MQPG1302-MQPG1304: Decreased interest in sex If the respondent answered "Yes" to the initial question (G13: decreased interest in sex), a series of additional questions was asked (MQPG1302- MQPG1304). If the respondent answered "No" to all three questions, then a code "6" (yes, but wasn't bothered) was entered for G13, indicating that the symptom was below the diagnostic threshold. If the respondent answered "Yes" to any one of these three additional questions, then the normal "probe" questions were asked, leading to an assignment of values 1, 3, 4, that is, whether the symptom was always due to physical illness or injury or medicine, alcohol, or drugs; any remaining parts of MQPG1302-MQPG1304 were skipped after a "Yes" response to any one of the probes. If the respondent volunteered that he/she had never been interested in sex, the value "5" (no interest ever) was coded. MQPG21-MQPG25: Depression module decision points Item G21 asks the interviewer whether three or more summary groups of the possible eight had at least one "Yes" response coded. If there were fewer than three, all the remaining DIS depression questions were skipped and the interviewer moved to the mania questions (G41-G49). If a respondent had three or more DSM-III symptoms during his/her life (G21), the interviewer asked one of two parallel series of questions to determine whether questions pertaining to the worst depressive episode should be asked. The series of questions are explained below: Series A, Questions G22, G23, and G26: G21 was coded "1" if there were three or more depressive symptoms and the respondent answered "Yes" to the initial question (G2) about two weeks or more of feeling sad, blue, or depressed. The respondent was then asked G22 about having these problems cluster in time, in the same month. If the answer was "Yes," G26 was asked. If the response to G22 was "No" (meaning the problems did not cluster in the same month), then a second question about temporal clustering was asked (G23). If the respondent again denied having problems cluster ("Yes, never been a period"), the remaining depression questions were skipped and the interviewer moved on to the mania questions. If the respondent said "No, has been a period" to G23, then G26 was asked. Series B Questions G24, G25, and G26: G21 was coded "2" if there were three or more depressive symptoms and the respondent answered "No" to the initial question (G2) about ever having had two weeks or more of feeling sad, blue, or depressed. G24 was then asked to determine if several of the depressive symptoms (G5-G20) were clustered together in the same month. If the answer to this was "No," then the remaining DIS depression questions were skipped and the interviewer moved on to the mania questions. If the answer was "Yes" then G25 was asked, which elicits symptoms of "masked depression." If the respondent indicated that he/she felt "low, gloomy, blue, or uninterested" then he/she was asked G26. If the respondent indicated that he/she felt "okay," the remaining DIS depression questions were skipped and the interviewer moved on to the mania questions. MQPG05W-MQPG20W: Worst episode depressive symptoms These questions ask about symptoms during the worst episode identified in G40. Each of the questions about a worst depressive episode is parallel to one of the lifetime depression questions: for example, MQPG05L asks "has there ever been a period of two weeks or longer when you lost your appetite?" The corresponding worst episode question, MQPG05W, asks, "Did you lose your appetite?" The worst episode question (in this example, MQPG05W) was only asked if the corresponding lifetime question (in this example, MQPG05L) was coded "1." The worst episode question was coded "Yes" or "No," indicating the presence or absence of the symptom during the worst depressive episode. A diagnosis of major depressive episode was based on the symptoms during the worst depressive episode (MQPG05W-MQPG20W) which are transformed into eight DSM-III symptom groups (MQPDGP1W-MQPDGP8W), and is not based on the lifetime depressive symptoms (MQPG05L-MQPG20L). MQPG41L-MQPG49L: Lifetime symptoms of mania The questionnaire inquires about whether a symptom has occurred at any time in life (G41-G49). Each of these (DIS) symptom questions can take a value of "1-3." The value "2" means the respondent said "No" or "don't know." If the respondent said "Yes," two additional "probe" questions were asked. The respondent was asked whether the symptom ever occurred when he/she used medicine, alcohol, or drugs. If the respondent said "Yes," then he/she was next asked whether the symptom always occurred when he/she used medicine, alcohol, or drugs. If the respondent said "Yes," then a "3" was coded. If the respondent said "No" to either question, than a "1" was coded. A value of "1" indicates that the possibility of this being a symptom of a mental disorder cannot be ruled out. When the interview was given on hard copy (i.e., not by computer - See MQPHCFLG, a flag for hard copy), responses to probe questions were not recorded so the probe questions are filled with 8's (blank but applicable). MQPG47EX: Examples of special gift or power If the respondent answered "Yes" to G47L, possessing a special gift or power, they were asked for an example. Since a high percentage of the examples given had to do with extra sensory perception (ESP), it was decided to code these examples into two categories, ESP and other. There were not enough examples with similar characteristics to code any other group. The query regarding special gifts or powers is intended to elicit reports of beliefs about the self which are psychotic in nature. If the example did not meet this precept, the symptom (MQPG47L) was coded "No" and the example deleted. MQPG50-MQPG54: Mania module decision points Item G50 asks the interviewer whether two or more lifetime symptoms of the possible eight (MQPG42L- MQPG49L) had at least one response of "1" coded. If there was a "Yes" response of one or less lifetime symptoms, all the remaining mania questions were skipped and the interviewer moved to the next section. The remaining DIS questions were coded as blank. If a respondent had two or more DSM-III symptoms during his/her life, the interviewer asked one of three parallel series of questions to determine whether questions pertaining to the worst episode of mania should be asked or possibly skipped to the next section. The three series are explained below: Series A, Questions G51, G52, and G55: G50 was coded "1" if there were two or more symptoms of mania and the respondent answered "Yes" to the initial question (G41) about one week or more of feeling high or manic. The respondent was then asked G51 about having these problems cluster in time, in the same month. If the answer was "Yes," G55 was asked. If the response to G51 was "No" (meaning the problems did not cluster in the same month), then a second question about temporal clustering was asked (G52). If the respondent again denied having problems cluster ("Yes, never been a period"), the remaining mania questions were skipped and the interviewer moved on to the next section. If the respondent said "No, has been a period" to G52, G55 was asked. Series B, Questions G53-G55: G50 was coded "2" if there were three or more symptoms of mania and the respondent answered "No" or "Always due to medication/drugs/alcohol" to the initial question (G41) about ever having had one week or more of feeling high or manic. G53 was then asked to determine if several of the depressive symptoms (G42-G49) were clustered together in the same month. If the answer to this was "No," then the remaining DIS mania questions were skipped and the interviewer moved on to the next section. If the answer was "Yes" then G54 was asked, which elicits symptoms of irritable mood. If the respondent indicated that he/she felt "unusually irritable or likely to fight or argue" then he/she was asked G55. If the respondent indicated that he/she never felt irritable, the remaining DIS mania questions were skipped and the interviewer moved on to the next section. Series C: G50 was coded "3" if: 1) there were only two symptoms of mania coded "1" and the respondent answered "No" or "Always due to medication/drugs/alcohol" to the initial question (G41) about ever having had one week or more of feeling high or manic, i.e., responses "2" or "3;" or, 2)there was only one or less symptoms of mania coded "1." With these combinations, the remaining DIS mania questions were skipped and the interviewer moved on to the next section. MQPG42W-MQPG49W: Worst episode symptoms of mania These questions ask about symptoms during the worst episode of mania identified in G66. Each of the questions about a worst episode of mania is parallel to one of the lifetime mania questions: for example, MQPG42L asks "has there ever been a period of a week or more when you were so much more active than usual that you or your family or friends were concerned about it?" The corresponding worst episode question, MQPG42W, asks, "Were you so much more active than usual that you or your family or friends were concerned about it?" The worst episode question (in this example, MQPG42W) was only asked if the corresponding lifetime question (in this example, MQPG42L) was coded "1." The worst episode question was coded "Yes" or "No," indicating the presence or absence of the symptom during the worst episode of mania. A diagnosis of manic episode was based on the symptoms during the worst episode of mania MQPG42W- MQPG49W) which were transformed into seven DSM-III symptom groups (MQPMNG1W-MQPMNG7W), and is not based on the lifetime symptoms of mania (MQPG42L- MQPG49L). MQPDGP1W-MQPDGP8W, MQPDYSFR, MQPDEP: The diagnostic variable "MQPDEP" The variable MQPDEP indicates the diagnosis of major depressive episode which is based on Criteria A and B of the DSM-III definition of major depressive episode. Criteria C and D were not assessed, and E was only assessed for bereavement. The minimum severity requirement is that these symptoms cause help-seeking or subjective impairment (at least one "Yes" to G28-G31). Criterion A for the diagnosis of major depressive episode in DSM- III calls for "dysphoric mood or loss of interest or pleasure in all or almost all usual activities and pastimes." If the respondent said "Yes" to the initial depression question (G2), or if there were at least two weeks of dysphoria combined with some other problems (G26), then the person was said to have "dysphoria," and was considered to have met Criterion A for the diagnosis of major depressive episode (MQPDYSFR=1). The DSM-III definition of Criterion B for major depressive episode contains eight symptoms, at least four (4 <=MQPDGPSW <= 8) of which must be present during a depressive episode in order to qualify for a diagnosis. These eight symptoms are approximated by the following NHANES III questions (Note that the DSM-III Symptoms are given in the order that they are asked in the DIS, rather than the order in the DSM-III Manual): DSM-III Symptom NHANES III Questions 1. Appetite or weight change G05W, G06W, or G07W 2. Insomnia or hypersomnia G08W or G09W 3. Loss or energy, fatigue G10W 4. Agitation or retardation G11W or G12W 5. Loss of interest in sex G13W 6. Feeling worthless or guilty G14W 7. Trouble thinking, concentrating G15W or G16W 8. Thoughts of death or suicide G17W, G18W, G19W, or G20W MQPDGP1W-MQPDGP8W give the number of positive items per group for the eight corresponding groups above. Criterion "E" is only assessed by the absence of uncomplicated bereavement as the cause of depression, i.e., depressed spells were never due to the death of someone close to the respondent or they may have been caused by things other than death (MQPG34 = 2). The variable MQPDEP can take seven values: 1 No diagnosis 2 Major depressive episode without severity 3 Major depressive episode with severity 4 Severe bereavement 5 Non-severe bereavement 88 Blank but applicable Blank MQPDEP = 1. No major depressive episode was diagnosed if the respondent answered sufficient questions so that Criteria A and B could be determined and did not qualify for a diagnosis of major depressive episode or bereavement (as defined below). MQPDEP = 2. Major depressive episode without severity was diagnosed if Criteria A, B and E were met but without severity (all no's for G28-G31). MQPDEP = 3. Major depressive episode with severity was diagnosed if Criteria A, B, and E were met plus severity (at least one "Yes" to G28-G31). MQPDEP = 4. Severe bereavement meets Criteria A and B plus severity (i.e., MQPDEP=3), but depressed spells ONLY due to death of someone close (MQPG34=1). MQPDEP = 5. Non-severe bereavement meets Criteria A and B but not severity (i.e., MQPDEP=2), but depressed spells ONLY due to death of someone close (MQPG34=1). MQPDEP = 88. The major depressive episode variable was coded a "Blank but applicable" value if the respondent did not answer sufficient questions so that Criteria A and B could be determined. The respondent must answer the initial depression question (MQPG02) and at least 11 of the lifetime symptom questions (MQPG05L-MQPG20L) as well as the appropriate worst episode symptom questions (MQPG05W-MQPG20W). MQPDEP = Blank. The major depressive episode variable was coded a "Blank" if the sample person was not eligible to receive the depression questions. MQPDPSX1-MQPDPSX2, MQPDGPSW: Total depressive symptom group counts The two variables MQPDGPSW and MQPDPSX2 report the total number of positive depressive symptom groups in the worst episode (sum of all groups where MQPDGP1W to MQPDGP8W contained at least one positive symptom) and lifetime (sum of all groups where MQPDGP1L to MQPDGP8L contained at least one positive symptom), respectively. The latter also adds dysphoria (MQPDYSFR=1). These variables range from 0-8 and 0-9, respectively. MQPDGPSW is used in determining the diagnosis of major depressive episode and MQPDPSX2 is used in the total symptom count. The variable MQPDPSX1 reports the total number of positive symptoms in the worst episode (sum of MQPDGP1W to MQPDGP8W) plus dysphoria (MQPDYSFR=1) with a range of 0-17. (Note that this variable is a sum of positive symptoms, not positive symptom groups.) MQPFDDP, MQPLDDP: Age of first and last depressive symptoms The two variables MQPFDDP and MQPLDDP code the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for any major depressive episode (2 <= MQPDEP <= 5). MQPFDDP uses the age in MQPG32 and MQPLDDP combine the age and time frame information in MQPG35, MQPG36 and MQPG37. MQPMNGP1-MQPNMGP7, MQPEUFOR, MQPMANIA: The diagnostic variable "MQPMANIA" The variable MQPMANIA indicates the diagnosis of manic episode which is based on Criteria A and B of the DSM-III definition of manic episode. Criteria C, D and E were not assessed. The minimum severity requirement is that these symptoms cause help-seeking or subjective impairment (at least one "Yes" in MQPG57-MQPG60). Criterion A for the diagnosis of manic episode in DSM-III calls for "one or more distinct periods with a predominantly elevated, expansive, or irritable mood." If the respondent said "Yes" to the initial mania question (MQPG41L=1) then the respondent was considered euphoric (MQPEUFOR=2). If the respondent said "Yes" (1) to MQPG54 then the respondent was considered irritable (MQPEUFOR=1). The DSM-III definition of Criterion B for manic episode requires a duration of at least one week during which, for most of the time, at least three of the seven symptoms have persisted (four if the mood is only irritable) and have been present to a significant degree. These seven symptoms are approximated by the following NHANES III questions: DSM-III Symptom NHANES III Questions 1. Hyperactivity/hypersexuality G42W or G44W 2. Pressure to keep talking G45W 3. Thoughts racing G46W 4. Inflated self-esteem e.g., special gifts or powers G47W 5. Decreased need for sleep G48W 6. Distractibility G49W 7. Excessive involvement in activities that have a high potential for painful consequences which is not recognized, e.g., buying sprees G43W MQPMNG1W-MQPMNG7W give whether the symptom is present or not for the seven corresponding groups above. The variable MQPMANIA can take five values: 1 No diagnosis 2 Manic episode without severity 3 Manic episode with severity 88 Blank but applicable Blank MQPMANIA = 1. No mania episode was diagnosed if the respondent answered sufficient questions so that Criteria A and B could be determined and did not qualify for a diagnosis of manic episode. MQPMANIA = 2. Manic episode without severity was diagnosed if Criteria A and B were met but without severity (all no's for MQPG57-MQPG60). MQPMANIA = 3. Manic episode with severity was diagnosed if Criteria A and B were met as well as severity (at least one "Yes" for MQPG57-MQPG60). MQPMANIA = 88. The manic episode variable was coded a "Blank but applicable" value if the respondent did not answer sufficient questions so that Criteria A and B could be determined. The respondent must answer the initial mania question (MQPG41), or the irritability question (MQPG54), and at least 6 of the lifetime symptom questions (MQPG41L-MQPG49L) as well as the appropriate worse episode symptom questions (MQPG42W-MQPG49W). MQPMANIA = Blank. The manic episode variable was coded a "Blank" if the sample person was not eligible to receive the mania questions. MQPMNGSW, MQPMNSX1-MQPMNSX2: Total manic symptom group counts The two variables MQPMNGSW and MQPMNSX2 code the total number of positive manic symptom groups in the worst episode (sum of groups MQPMNGP1 to MQPMNGP7 with a "Yes" response) and during lifetime (questions MQPG42L to MQPG49L are grouped into DSM-III groups 1 to 7 and the number of positive groups is counted), respectively. The latter also adds the euphoria or irritability symptom (1 <= MQPEUFOR <= 2). These variables range from 0-7 and 0-8, respectively. MQPMNGSW is used in determining the diagnosis of manic episode and MQPMNSX2 is used in the total symptom count. The variable MQPMNSX1 reports the total number of positive symptoms in the worst episode (sum of MQPMNGP1 to MQPMNGP8) plus euphoria or irritable mood (1 <= MQPEUFOR <= 2) with a range of 0-8. (Note that this variable is a sum of positive symptoms, not positive symptom groups). MQPFDMN, MQPLDMN: Age of first and last manic symptoms The two variables MQPFDMN and MQPLDMN report the age of the respondent the first and last time, respectively, he/she experienced manic symptoms if he/she ever met criteria for any manic episode (2 <= MQPMANIA <= 3). MQPFDMN uses the age in MQPG61 and MQPLDMN combines the age and time frame information in MQPG62, MQPG63 and MQPG64. MQPDEPSE: The diagnostic variable "MQPDEPSE" The variable MQPDEPSE indicates the DSM-III diagnosis of major depression, single episode, and is constructed using MQPDEP and MQPMANIA. The diagnosis of major depression, single episode is not made if the depression is the sole result of severe or non-severe bereavement (MQPDEP= 4 or 5) or if a manic episode is present (MQPMANIA= 2 or 3). There must be only one episode of major depression. The variable MQPDEPSE can take five values: 1 No diagnosis 2 Major depression, single episode without severity 3 Major depression, single episode with severity 88 Blank but applicable Blank MQPDEPSE = 1. No major depressive episode was diagnosed (MQPDEP=1) although there could be severe or non-severe bereavement (MQPDEP=4 or 5) or some form of mania was diagnosed (MQPMANIA=2 or 3). MQPDEPSE = 2. A single episode (MQPG27=1) of major depression without severity was diagnosed (MQPDEP=2) and no manic episodes were present (MQPMANIA=1). MQPDEPSE = 3. A single episode (MQPG27=1) of major depression with severity was diagnosed (MQPDEP=3) and no manic episodes were present (MQPMANIA=1). MQPDEPSE = 88. The major depression, single episode variable was coded "Blank but applicable" if one of the following is true: 1. MQPDEPSE=1 and MQPBIPOL= (Blank or 88) and MQPDEP= (Blank or 88) 2. MQPDEPSE=1 and MQPBIPOL= (Blank or 88) and MQPDEP=3 3. MQPDEPSE=1 and MQPBIPOL=1 and MQPDEP= (Blank or 88) 4. MQPDEPSE=1 and MQPBIPOL=1 and MQPDEP=3 and MQPG27= (Blank, 888, or 999) MQPDEPSE = Blank. The major depression, single episode variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDDSE, MQPLDDSE: Age of first and last depressive symptoms associated with major depression, single episode The two variables MQPFDDSE and MQPLDDSE code the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for a major depression, single episode which was not due solely to bereavement (2 <= MQPDEPSE <= 3). MQPFDDSE uses the age in MQPFDDP and MQPLDDSE uses the age in MQPLDDP. MQPDEPRT: The diagnostic variable "MQPDEPRT" The variable MQPDEPRT indicates the DSM-III diagnosis of major depression, recurrent, and is constructed using MQPDEP and MQPMANIA. The diagnosis of major depression, recurrent, is not made if the depression is the sole result of severe or non-severe bereavement (MQPDEP=4 or 5) or if a manic episode is present (MQPMANIA= 2 or 3). There must be more than one episode of major depression. The variable MQPDEPRT can take five values: 1 No diagnosis 2 Major depression, recurrent without severity 3 Major depression, recurrent with severity 88 Blank but applicable Blank MQPDEPRT = 1. No major depressive episode was diagnosed (MQPDEP=1) although there could be severe or non-severe bereavement (MQPDEP=4 or 5) or some form of mania was diagnosed (MQPMANIA=2 or 3). MQPDEPRT = 2. Recurrent episodes (2 <= MQPG27 <= (whole life) or don't know how many spells) of major depression without severity were diagnosed (MQPDEP=2) and no manic episodes were present (MQPMANIA=1). MQPDEPRT = 3. Recurrent episodes (2 <= MQPG27 <= (whole life) or don't know how many spells) of major depression with severity were diagnosed (MQPDEP=3) and no manic episodes were present (MQPMANIA=1). MQPDEPRT = 88. The major depression, recurrent variable was coded "Blank but applicable" if one of the following is true: 1. MQPDEPRT=1 and MQPBIPOL= (Blank or 88) and MQPDEP= (Blank or 88) 2. MQPDEPRT=1 and MQPBIPOL= (Blank or 88) and MQPDEP=3 3. MQPDEPRT=1 and MQPBIPOL=1 and MQPDEP= (Blank or 88) 4. MQPDEPRT=1 and MQPBIPOL=1 and MQPDEP=3 and MQPG27= (Blank, 888, or 999) MQPDEPRT = Blank. The major depression, recurrent variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDDRT, MQPLDDRT: Age of first and last depressive symptoms associated with major depression, recurrent The two variables MQPFDDRT and MQPLDDRT report the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for major depression, recurrent, which was not due solely to bereavement (2 <= MQPDEPRT <= 3). MQPFDDRT uses the age in MQPFDDP and MQPLDDRT uses the age in MQPLDDP. MQPDYSA, MQPDYSD, MQPDYSTH: The diagnostic variable "MQPDYSTH" The variable MQPDYSTH indicates the diagnosis of dysthymic disorder. The diagnosis of dysthymic disorder is based on Criteria A through D of the DSM-III definition of dysthymic disorder. Criteria E and F were not assessed. This disorder differs from major depressive disorder in that during the past two years, the individual has been bothered most or all of the time by symptoms characteristic of the depressive syndrome but that are not of sufficient severity and duration to meet the criteria for a major depressive episode. Criteria A, B, and C of the DSM-III are encompassed in the variable MQPDYSA. This requires two years or more of predominately depressive mood or marked loss of interest or pleasure in all, or almost all, usual activities and pastimes (MQPG03=1 or 104 weeks <= MQPG26 <= whole life). The DSM-III definition of Criterion D for dysthymic disorder contains 13 symptoms, at least three (3 <= MQPDYSD <= 7) of which must be present during the depressive periods in order to qualify for a diagnosis. Seven of these symptoms are covered by the following NHANES III questions. DSM-III Symptom NHANES III Questions 1. Insomnia or hypersomnia G08L or G09L 2. Low energy, chronic tiredness G10L 3. Feeling inadequate/low self- esteem G14L 5. Trouble thinking G15L or G16L 7. Less interest in pleasurable activities G13L 10. Less active or talkative G11L or G12L 13. Recurrent thoughts of death or suicide G17L or G18L or G19L DSM-III symptoms not available in the NHANES III 4. Decreased effectiveness 6. Social withdrawal 8. Irritability 9. Lack of pleasure in rewards 11. Brooding about the past or self-pity 12. Crying spells The variable MQPDYSTH can take five values: 1 No diagnosis 2 Dysthymic disorder with no major depressive episode 3 Dysthymic disorder with major depressive episode 88 Blank but applicable Blank MQPDYSTH = 1. No dysthymic disorder was diagnosed if the respondent answered sufficient questions so that Criteria A through D could be determined and did not qualify for a diagnosis of dysthymic disorder. MQPDYSTH = 2. Dysthymic disorder was diagnosed if the respondent met Criteria A through D but did not have a diagnosis of major depressive episode (MQPDEP not equal to 3). MQPDYSTH = 3. Dysthymic disorder was diagnosed if the respondent met Criteria A through D and had a diagnosis of major depressive episode as well (MQPDEP = 3). MQPDYSTH = 88. The dysthymic disorder variable was coded a "Blank but applicable" value if the respondent did not answer sufficient questions so that Criteria A through D could be determined. The respondent must answer the initial two year depression question MQPG03 or the length of spell question MQPG26 and at least nine of the 12 lifetime symptom questions listed above for Criterion D plus MQPG03. MQPDYSTH = Blank. The dysthymic disorder variable was coded a "Blank" if the sample person was not eligible to receive the depression questions. MQPBIPOL: The diagnostic variable "MQPBIPOL" The variable MQPBIPOL indicates the DSM-III diagnosis of bipolar disorder, and is constructed using MQPDEP and MQPMANIA. The diagnosis of bipolar disorder is made only if there has ever been a manic episode. The variable MQPBIPOL can take eight values: MQPBIPOL = 1. No bipolar disorder was diagnosed if there has never been a diagnosis of manic episode. MQPBIPOL = 2. Bipolar disorder is diagnosed if severity and exclusion criteria are met for both a manic and a major depressive episode (MQPMANIA=3 and MQPDEP=3). MQPBIPOL = 3. Bipolar disorder is diagnosed if severity and exclusion criteria are met for a manic episode (MQPMANIA=3), but a major depressive episode is either absent (MQPDEP=1, 4 or 5) or the diagnosis is missing (MQPDEP=Blank or 88). MQPBIPOL = 4. Bipolar disorder is diagnosed if severity and exclusion criteria are met for a manic episode (MQPMANIA=3), but not for a major depressive episode (MQPDEP=2). MQPBIPOL = 5. Bipolar disorder is diagnosed if no manic episode met both severity and exclusion criteria (MQPMANIA=2) and a major depressive episode is either absent (MQPDEP=1, 4 or 5) or the diagnosis is missing (MQPDEP=Blank or 88). MQPBIPOL = 6. Bipolar disorder is diagnosed if no manic episode met both severity and exclusion criteria (MQPMANIA=2) and the major depressive episodes may or may not meet both severity and exclusion criteria (MQPDEP=2 or 3). MQPBIPOL = 88. The bipolar disorder variable was coded a "Blank but applicable" value if the diagnosis for manic episode is missing (MQPMANIA=Blank or 88). MQPBIPOL = Blank. The bipolar disorder variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDBI, MQPLDBI: Age of first and last manic symptoms associated with bipolar disorder The two variables MQPFDBI and MQPLDBI report the age of the respondent the first and last time, respectively, he/she experienced manic symptoms if he/she ever met criteria for any bipolar diagnosis (2 <= MQPBIPOL <= 6). MQPFDBI uses age at first manic symptoms (MQPFDMN) when 2 <= MQPBIPOL <= 6 or age at first depressive symptoms (MQPFDDP) if MQPBIPOL=2, 4 or 6 and 0 <= MQPFDDP <= MQPFDMN. MQPLDBI uses age at last manic symptoms (MQPLDMN) when 2 <= MQPBIPOL <= 6 or age at last depressive symptoms (MQPLDDP) if MQPBIPOL=2, 4 or 6 and MQPLDDP >= 0 and MQPLDMN <= MGPLDDP <= 54. MQPBIPII: The diagnostic variable "MQPBIPII" The variables MQPDEP and MQPMANIA report the DSM- III syndromes of major depressive episode and manic episode, respectively, and are used to construct various DSM-III diagnoses. The variable MQPBIPII is the DSM-III diagnosis of atypical bipolar disorder (bipolar disorder, type II). The diagnosis of atypical bipolar disorder is made only if the respondent: 1. Does not meet criteria for bipolar disorder (MQPBIPOL=1) 2. Does not meet criteria for a manic episode (MQPMANIA=1) 3. Has a major depressive episode (MQPDEP=2 or 3) 4. Has euphoria or irritability (1 <= MQPEUFOR <= 2) 5. Has some symptoms of mania (1 <= MQPMNGSW <= 3) The variable MQPBIPII can take five values: 1 No diagnosis 2 Atypical bipolar disorder without severity 3 Atypical bipolar disorder with severity 88 Blank but applicable Blank MQPBIPII = 1. No atypical bipolar disorder is diagnosed if there has ever been a manic episode (2 <= MQPMANIA <= 3) or bipolar disorder (2 <= MQPBIPOL <= 6) and a major depressive episode is absent or missing (MQPDEP=1, 4, 5, 88, or Blank). MQPBIPII = 2. Atypical bipolar disorder without severity is diagnosed if a major depressive episode without severity is present (MQPDEP=2) and the criteria for a manic episode is not met (MQPMANIA=1) but euphoria or irritability is present (1 <= MQPEUFOR <= 2) and some manic symptoms are present (1 <= MQPMNGSW <= 3). MQPBIPII = 3. Atypical bipolar disorder with severity is diagnosed if a major depressive episode with severity is present (MQPDEP=3) and the criteria for a manic episode is not met (MQPMANIA=1) but euphoria or irritability is present (1 <= MQPEUFOR <= 2) and some manic symptoms are present (1 <= MQPMNGSW <= 3). MQPBIPII = 88. The atypical bipolar disorder variable was coded "Blank but applicable" if one of the following is true: MQPBIPII=1 and MQPDEP= (Blank or 88) 2. MQPBIPII=1 and MQPMANIA= (Blank or 88) and MQPDEP=3 MQPBIPII = Blank. The atypical bipolar disorder variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDBII, MQPLDBII: Age of first and last manic symptoms associated with atypical bipolar disorder The two variables MQPFDBII and MQPLDBII report the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for any atypical bipolar disorder diagnosis (2 <= MQPBIPII<= 3). MQPFDBII uses age at first depressive symptoms (MQPFDDP) and MQPLDBII uses age at last depressive symptoms (MQPLDDP).
