If you prefer to work with smaller files, or files for a specific wave, you may wish to download the following codebook files. (Please note: All of the below documents are included in the larger codebook.pdf file above.)

For ease of use, the full CLOC study has been subset into four primary datasets. Users should use the dataset that corresponds to their particular analytic objective. All data files can be downloaded below, or can be accessed through the ICPSR webpage. Each file is available in a .sav format (SPSS file) or in a .por format (portable file).
CLOC: The Core Dataset: contains all available variables from all four waves (Baseline, W1, W2, W3) for the entire sample of 1532 persons (excluding clones). Almost all analyses can be performed using this large dataset. [spss] [.por]
CLOC Baseline Only: contains all variables collected at the baseline interview (v1-v957) for the entire sample of 1532 persons (excluding clones). It also contains the baseline physiological variables (v20001-v20991) from the subsample of 432 persons who also participated in the baseline MacBat portion of the study. This dataset is most useful for cross-sectional analyses of older adults. [spss] [.por]
CLOC Widowed-Control Only: contains all available data from anyone who participated as either a widowed person or a control subject in at least one of the three CLOC follow-up surveys (W1, W2, W3). This dataset is available with or without clones (n=545 subjects, excluding clones) (n=558, including clones). This dataset is most appropriately used for longitudinal analyses of the consequences of widowhood. [spss with no clones] [.por with no clones] [spss with clones] [.por with clones]
CLOC Couples Only: The CLOC study collected baseline data from both the husband and the wife of 423 couples (n=846). This datafile includes all available data from all four waves of data collection (BA, W1, W2, W3) for these 423 couples. Each line of data contains a set of "v" variables" and a set of "s" variables. The "v" variables are data from the wife of the couple, and the "s" variables are data from the husband. This dataset is appropriate for couple-level analyses. [spss] [.por]
A final CLOC Clones dataset is included for the advanced user. This datafile contains data for the 13 individuals who are identified as clones. Clones are people who participated twice in either the W1 or W2 follow-up interview - first as a control subject, and then later as a widowed subject. Unless you are using a case-control matched design, the average user will probably choose to exclude clones from their analyses. Please note: there is already a version of the widow-control datafile that contains the 'cloned' records. [spss] [.por]
