Survey Research Core (SRC)

Survey Research Core (SRC)
The Survey Research Core (SRC) is a shared resource, supported by the City of Hope Comprehensive Cancer Center, to help investigators conduct research using survey methodology. The SRC provides a wide range of services in the areas of study design and sampling, survey instrument development and evaluation, data coding, collection, management, analysis and reporting.

The overall goal of the SRC is to provide high quality, standardized services to conduct survey-based research. The SRC staff work closely with investigators to design the best possible study to meet the specific challenges of the research question.

The SRC provides the expertise, resources, facilities, and staff and utilizes instruments such as telephone surveys, face-to-face interviews, web surveys, and mailed questionnaires.

Services provided include:


  • Study design and sampling
  • Instrument development and pre-testing
  • Data collection and entry
  • Data coding and entry
  • Data management
  • Data analysis and reporting
Research reported in this publication included work performed in the Survey Research Core supported by the National Cancer Institute of the National Institutes of Health under award number P30CA33572.

Abstract for Grants

Located in the Population Sciences building, the Survey Research Core (SRC) is a shared resource facility based in the Cancer Control and Population Sciences Program of the City of Hope Comprehensive Cancer Center.
It is directly involved in research at City of Hope, from the inception of a research idea involving survey-based methodology, to analysis and final publication of results.
The specific functions provided by the SRC include sample selection to meet the stated hypotheses and aims of the proposal, survey design and pre-testing, implementation and monitoring of mailed and on-line surveys, implementation of all aspects of telephone surveys, as well as tracking study subjects lost to follow-up and automated data entry.
The SRC has highly trained personnel to maximize the efficiency, reduce the cost and optimize the participation rates required for the various aspects of survey-based research. The Core works in close collaboration with Ph.D.-level biostatisticians to provide the expertise needed for projects of any type or scale.
The SRC utilizes a Tailored Design Method to organize multiple mailings for mailed survey to maximize response rate and minimize non-response bias.
The SRC ensures high volume; high accuracy automated content capture using the Cardiff Teleform Information Capture System. Cardiff Teleform is a complete system for creating and capturing data from printed forms. Teleform can perform hand-print, machine-print, check-box and barcode recognition with exceptional accuracy.

Study design and sampling
  • Consultation with investigators on the most appropriate design for the proposed research project.
  • Identification of a sampling frame that accurately reflects the target population.
Instrument development and pre-testing
  • The SRC provides assistance with the development and design of questionnaires. We work in close collaboration with investigators to ensure that valid, reliable data is obtained from the population surveyed.
Data collection and entry
  • Projects are administered by means of mailed, telephone, face-to-face, and on-line surveys.
  • An automated data entry system is used for mailed surveys.
Data coding and entry
  • Open-ended questionnaires are coded and entered by experienced staff.
Data management
  • A project database tailored to meet the needs of the study is created using a variety of software to suit the investigator’s preference, with the capability to export data into SAS, SPSS, SQL, EXCEL, ACCESS etc.
Data analysis and reporting
  • Statistical support for data analysis is provided, with generation of a final report with tables, charts, and graphs combined with narrative comments.

These services are offered individually, in a variety of combinations, or as a complete package, depending on the investigator’s preference.

Using the Facility

Quality Assurance
The SRC provides individualized attention to investigators during each stage of the research project, from initial data assessment to collection needs, to survey design and interpretation of results.
Well-tested and highly developed quality-assurance procedures and controls are in place throughout all stages of the project.
Surveys are pre-tested and well-developed coding procedures are followed for open-ended questions.
TheCardiff Teleform Information Capture Systemis a major component of the SRC’s quality control process. It eliminates potential errors that could occur with manual data entry.
For data entry, 100 percent verification is standard procedure. The SRC conducts verification checks of all data prior to issuing a final project report. Telephone and face-to-face interviews are conducted using strict quality-assurance and extensive tracking procedures. Multiple mailings, follow-up postcards, and postage-paid return envelopes are used to ensure high response rates in mailed surveys.
The SRC provides expertise in study design and sampling, survey and questionnaire design, data collection and management, and advanced statistical support.
An epidemiologist and a biostatistician will work closely with investigators to choose the right study and questionnaire design, determine the most efficient sampling frame and size for the study.
The SRC ensures high volume, high accuracy, high quality data collection, rapid turnaround time, and automated content capture using theCardiff Teleform Information Capture System. Cardiff Teleform is a complete system for creating and capturing data from printed forms. Teleform can perform hand-print, machine-print, check-box, and barcode recognition with exceptional accuracy.
Form inventory
The SRC maintains an inventory of standardized questionnaires for all purposes including psychological, demographic, food frequency, and quality of life, among others. Please contact the SRC Director for further information.
