STUDY DESCRIPTION: The California Department of Health Services conducts surveys of attitudes, behaviors, and media exposure regarding smoking and tobacco use as components of the smoking cessation evaluation effort required by California Assembly Bills AB75, AB99 and AB816. The objective of these surveys is to collect representative statewide data on cigarette smoking behavior, attitudes towards smoking, media exposure to smoking, and use of tobacco products other than cigarettes, from adults and teenagers living in California. These surveys are conducted approximately every three years through contracts with the University of California, San Diego (UCSD) and Westat, Inc. to measure changes in attitudes and behaviors in the California population. The California Tobacco Survey (CTS) was conducted in 1990-1991, 1992, 1993, 1996, 1999 and 2002. The 1990-1991 survey includes an adult pregnancy supplement.

Data for each survey year consists of a basic set of three surveys (household screener, adult ages 18+ and adolescent ages 12-17). Household screener surveys interview the initial household respondent and are used to select adult and adolescent survey respondents. Demographic and regional geographic variables are included in the surveys. The 1996 CTS contains a short adult survey that is similar to the 1993 adult survey and a long adult survey that is similar to the 1992 adult survey. The 1999 and subsequent CTS surveys use an adult survey similar to the 1996 long adult survey. Users of these data should note that variables are deleted, changed or added over time.

In addition to basic surveys, a Teen Longitudinal Survey was conducted from 1993 through 1999. The 1993 CTS Teen survey provided the baseline data, with follow-up surveys conducted in 1996 and 1999 (when participants were 18 years old and over). Both the teen-only (1993-1996) and full (1993-1996-1999) surveys have been released as public-use data. Each survey data file contains data for only those individuals interviewed in the relevant waves.

EXTENT OF COLLECTION: Data files + Technical Reports + Final Reports

• DOCUMENTATION: These data files are documented by printed and machine-readable reports and files. The majority of the machine-readable documentation is available in Portable Document Format. The PDF format was developed by Adobe Systems Incorporated and can be accessed using the Adobe Acrobat Reader. A copy of the Acrobat Reader can be downloaded free from Adobe.

• TECHNICAL REPORTS (PDF): Technical reports provide descriptions of survey methodology and include survey questionnaires. Survey questionnaires should be consulted for information on the exact wording of survey questions and for skip patterns. Technical reports also document variable names, labels and column locations for the ASCII data files in the Public Use Data File Documentation section (see volume two of the technical report).

• FINAL REPORTS (PDF): Final reports present summary analysis and data (figures and tables) that document the reduction in smoking prevalence following the increase in the tobacco excise tax and implementation of a comprehensive California Tobacco Control Program that was funded by the voter sponsored Tobacco Tax Initiative (Proposition 99 of 1988).

• SAS DATA DEFINITION STATEMENTS (ASCII): Data input statements are text files that can be used by SAS to read the ASCII data files. These statements include variable names, labels and column locations. Users should edit these files for compatibility with their systems, and to suit their specific requirements.

• DATA FILES: Data files for all surveys are available in three file formats.

1. ASCII
2. SAS for Windows
3. SAS Transport - These files are not specific to a computer platform and can be opened in any operating system running SAS statistical software.

RESTRICTIONS: These data are to be used only for the purpose of health statistical reporting and analysis. Participants in the surveys have been assured confidentiality; no effort should be made to determine the identity of any participant(s). Data used in published works or any form of public dissemination should acknowledge the California Tobacco Survey as the original source. The suggested citation, "Source: California Tobacco Survey, (year)", should appear at the bottom of all tables and figures. Published or publicly disseminated data must also include a disclaimer that credits any analyses, interpretations, or conclusions reached to the author and not to the California Tobacco Control Program or the University of California. Users who wish to publish a technical description of the data should make a reasonable effort to insure that the description is not inconsistent with that provided by the survey authors.
