- No. Please note that few screening questions (SC2, SC2.1, SC2.2, SC2.3, SC8.1, SC8.2) were removed during the NCS-R data collection in 2001-2002. The CPES released dataset included valid answers provided by NCS-R respondents who were interviewed before these questions were removed and NCS-R respondents who were not interviewed with these questions were counted as "Missing (System)" on these questions. Below is the list of questions and please click links to view the summary statistics and/or frequencies:
- SC2 - How long have you lived at your current address?
- SC2.1 - About how many years have you lived in this state?
- SC2.2 - About how many miles do you currently live from the place where you were raised during most of your childhood?
- SC2.3 - How many different houses or apartments have you lived in since the age of 18?
- SC8.1 - How would you rate your overall physical health -- excellent, very good, good, fair, or poor?
- SC8.2 - How would you rate your overall mental health -- excellent, very good, good, fair, or poor?
- No. Some questions were asked in one study and not in the others. Questions not asked of all respondents include the following:
- Age under 45: The Attention Deficit/Hyperactivity (AD), Oppositional Defiant Disorder (OD), and Conduct Disorder (CD) sections were administered only to individuals who were under the age of 45.
- The National Comorbidity Survey Replication (NCS-R) had two Parts: Part 1 included a core diagnostic assessment of all 9,282 respondents. Part 2 was administered only to 5,692 of the 9,282 Part 1 respondents, including all Part 1 respondents with a lifetime disorder plus a probability subsample of other respondents. See the Final Weights section of the User Guide section of About CPES for an explanation of the two parts and the implications for weighting analyses.
- The National Survey of American Life (NSAL) Black Caribbean sample had some questions that no one else had.
- The National Survey of American Life (NSAL) had several sections which were not administered to the White sample. See below for a list of sections skipped if the NSAL respondent was White.

- Unfortunately, the response options in CPES may never be defined to the level that you want. It was up to the respondent to determine whether they received services in either mental health setting or human service settings.
- All of the system missing cases are due to conditions in which a particular respondent did not receive the question but the reason could vary from case to case.
- The personality items can be found at Interactive Codebook and cover PEA40 - PEA49 (Zuckerman Social Desirability) and PEA50-PEA83 (IPDE).However, the IPDE scale was the scale used in the Lenzenweger paper. Using the clinical interview NCS-R came up with the best predictors of 6 IPDE diagnoses and generated predicted probabilities for each of the full part 2 NCS-R samples. However, NCS-R did not make the personality disorder diagnostic variables public since they are NCS-R has 10 multiply imputed values for each disorder (generated 10 yes/no values from the predicted probabilities).
- You can view the universe of respondents for each question in the separate surveys bychoosing the ?View Universe? link on the variable pages in the Interactive Codebook section of the CPES Web site. The actual questionnaires for each survey are also available through the links to each of the project sites on the CPES home page. These questionnaires also have routing instructions included.
- The SESTRAT within SECLUSTR values are currently set up as strata with a value of either 1 or 2 in the cluster or SECU variable. They are unique records within those variables but Mplus requires a unique cluster value within the strata. It is easy to just renumber and create new variables.For example, in a data set with 100 records and SESTRAT ranges from 1-20 (just an example) and there are values of 1 or 2 in SECLUSTR then they could be renumbered to NEWSTRAT in 1-20 and NEWCLUSTR in 1 to 100 the total number in each of the NEWSTRAT variables.Old Strata, Old Cluster, New Strata, New Cluster1 1 1 11 1 1 21 2 1 31 2 1 42 1 2 52 2 2 6Etc. ?20 2 20 100Mplus requires unique strata/cluster combinations so this method allows you to define the records within Strata/PSU without changing the basic complex sample variable structure or meaning. The user could use the define statement in Mplus or do this outside of Mplus in the software of choice.
- The questions asked in the three separate surveys that comprise CPES were all administeredthrough Computer-Assisted Personal Interviewing (CAPI) software so the routing of the questions was often quite complex. The actual questionnaires for each survey are also available through the links to each of the project sites on the CPES home page. These questionnaires also have routing instructions included.
- The Interactive Codebook section on the CPES Web site provides the universe for each question, that is, the path for each question. Having said that, however, this is a complex set of questions made even more so by the fact that it is impacted by the long/short version of the NCS-R (see ?About CPES? for a description).The following logic is all online but varies by study.
You also indicate an interest in knowing whether the respondent was hospitalized for either a mental/emotional problem or a substance problem. There is no way to know this for sure, since SR2 lumps these all together. However, you could go back to each of the section-specific items and determine which were endorsed. The pitfall here is that respondent may give a positive answer at SR2 without having revealed a hospitalization in earlier sections -- in this case, you would never know the cause(s).
- NCS-R: All respondents who reach the Services (SR) section (i.e. are in Long Group) are asked SR2, regardless of their response to the "ever hospitalized" item in each of the earlier disorder sections. So, the missing cases at SR2 are only Short Group respondents (good news here is that if a respondent got as far as the "ever hospitalized" question in an earlier section, there is a very high likelihood that they would have been in the Long Group -- so you don't have to worry much about missing respondents who never reached the Services section).
- NSAL: There is an extra checkpoint (SR1) that evaluates the responses to all of the earlier "every hospitalized" items. If at least one YES response to the disorder-specific items, SR2 is not asked. So, for the missing SR2 cases, you will need to cross-reference all of the earlier items to see which one was endorsed (please also note that White respondents were not asked the Services section, so all Whites contribute to the missing values). The entire list of disorder-specific hospitalization items is included in the on-line documentation for SR1.
- NLAAS: Same structure as NSAL -- extra SR1 checkpoint that evaluates earlier disorder-specific hospitalization items. If at least one YES, SR2 is not asked. Again, the entire list of hospitalization items is listed at the SR1 online documentation.
- The core questionnaire was based largely on the World Health Organization's (WHO) expanded version of the Composite International Diagnostic Interview (CIDI) developed for the World Mental Health (WMH) Survey Initiative, the WMH-CIDI.
For more information, consult the Questionnaire Development section of About CPES, or view a 22-minute video of Ron Kessler speaking on the development of CIDI.
- There is no FPC variable created in the data set for public-use. A person who wants to incorporate a finite population correction could do so by creating his own FPC variable. In general, analysis of the CPES does not use a correction for FPC as it amounts to a very small correction in the end, due to large sample sizes to begin with.
- Item SC10.4b reads "Do you have the following conditions? A hearing problem that prevents you from hearing what is said in normal conversation even with a hearing aid?" This item appears to be asked of all respondents.Further down, there are 2 interviewer query items dealing with hearing loss -If the respondent says no to the hearing question (or other impairment questions) but the interviewer observes a hearing problem (or other impairment), this is an opportunity to probe with the respondent to be sure she or he had understood the original question. This is repeated for several of the ?observable? impairments when there appears to be a discrepancy between what the respondent said and what the interviewer observes.
- This describes the main scales we used in the NCS-R and then again in the NCS-A:The questions in the Personality sections include items from the social desirability scale of the Zuckerman Personality Scales and a subset of the screening questions from the screening scale developed in conjunction with the International Personality Disorder Examination (IPDE). The Zuckerman items were included to facilitate the study of social desirability response bias in the survey.The IPDE screening questions were included as a screening scale for a small clinical reappraisal study of personality disorders that was carried out in a probability sub-sample of NCS-R respondents. This reappraisal study administered the full IPDE. The method of multiple imputation (MI) was used to generate predicted probabilities of DSM-IV diagnoses of Clusters A, B, C, and any PDs (including NOS) as well as diagnoses of antisocial personality disorder and borderline personality disorder. The latter two were the only specific personality disorders included in the MI analysis due to the fact that we had a special interest in them and we included the full set of IPDE screening questions for those two but only a subset of screening questions for other personality disorders.A paper reporting the results of the analysis was written by Mark Lenzenweger et al: Lenzenweger, M.F., Lane, M.C., Loranger, A.W., Kessler, R.C. (2007). DSM-IV personality disorders in the National Comorbidity Survey Replication. Biological Psychiatry 62(6), 553-564.

- You may do this by choosing a variable that only respondents who answered Part 2 completed and then do a cross tabulation by the variable ?sex?. For example, all 5,692 participants answered Question DA39 (Is biological mother still living?). When this variable is cross tabulated with the variable ?sex?, the distribution is 2,382 males and 3,310 females (unweighted). You may want to try other variables from the long form in similar crosstabs to check the gender breakdown.
- Looking through Questionnaire sections and average time to administer section by study table in the Questionnaire Development section of About CPES, it is possible to determine which sections were included in more than one study.
- Although the Screening section was a core section, only questions SC20 to SC36 were used in all three studies.
- In the Personality section, only a subset of 10 Personality questions were considered core. The service use questions at the end of each core section also varied by study.
- There are also questions interspersed throughout the three study instruments that were included in two or all three studies.

- One question asks about the sexual orientation of the respondent in the NCS-R and NLAAS surveys. Please fine the variable "CN11_3" in the Interactive Codebook. For the frequencies of this variable for each survey, please find the variable, and click the "view the summary statistics and/or frequencies" in the Web site and see the further information!
This variable is only available in the restricted-use versions of these data files. Please see also variable "CN11_3" in the list of restricted variables.
- The National Comorbidity Survey Replication (NCS-R) Part 1 included a core diagnostic assessment of all 9,282 respondents and Part 2 was administered only to 5,692 of the 9,282 Part 1 respondents, including all Part 1 respondents with a lifetime disorder plus a probability subsample of other respondents. See NCS-R Part 1 and 2 Sample for more information. See Final Weights and Special Analysis Considerations for Weighted Analysis in the Weighting section of About CPES for an explanation of the two parts and the implications for weighting analyses.
- The Suicidality section has a skip at the very beginning (SD1). If the respondent was able to read, they were asked SD2-SD14, if not, they were asked SD15-SD27. Therefore, you need to combine the data from this series, e.g., combine V01995 and V02025, etc. Please also note that these questions were not asked of the entire NSAL sample (only African-American respondents were asked this in NSAL).
