Computer-Assisted Telephone Interviewing

Computer-assisted telephone interviewing (CATI) is a data collection method in which an interviewer conducts surveys over the phone using a computerized questionnaire. This approach combines the personal touch of telephone interviews with the efficiency and accuracy of computerized data collection.

Definition of CATI

CATI involves an interviewer using a computer system to guide the survey process while speaking with respondents over the phone. The interviewer reads questions displayed on the computer screen and enters the respondent’s answers directly into the system. This method improves data accuracy and streamlines the survey process.

Historical Context The concept of CATI emerged in the late 20th century as advancements in computer technology made it feasible to integrate computers into the survey process. Initially, CATI systems were used primarily by large market research firms and government agencies. Over time, as technology became more accessible and affordable, CATI gained widespread adoption across various industries.

Alternative Terms CATI is also known as:

Telephone Computer-Assisted Interviewing
Computer-Assisted Telephonic Interviewing

Who Uses CATI?

CATI is used by a wide range of organizations, including:

Market Research Firms: To conduct large-scale surveys and opinion polls.
Government Agencies: For census data collection and public opinion research.
Healthcare Organizations: To gather patient feedback and conduct health-related surveys.
Academic Researchers: For social science research and behavioral studies.

What is the Purpose of CATI?

The primary purpose of CATI is to improve the efficiency and accuracy of telephone surveys. It helps in:

Reducing Errors: Automated data entry minimizes manual errors associated with traditional paper-based surveys.
Enhancing Data Quality: Real-time validation and skip logic ensure consistent and complete responses.
Saving Time: Streamlined processes reduce the time needed for data collection and processing.

When is CATI Used?

CATI is particularly useful in situations requiring:

Large-Scale Surveys: Such as national opinion polls and customer satisfaction surveys.
Complex Questionnaires: Where skip patterns, branching, and real-time validations are needed.
High Response Rates: Telephone interviews generally yield higher response rates compared to other survey methods.

Why is CATI Important?

CATI offers several benefits that make it a valuable tool in data collection:

Efficiency: Speeds up the survey process by eliminating the need for paper-based data entry and subsequent digitization.
Accuracy: Reduces the likelihood of data entry errors and ensures that all responses are captured accurately.
Flexibility: Allows for complex questionnaire designs with automated skip patterns and branching logic.
Real-Time Data: Enables immediate data validation and storage, facilitating faster analysis and reporting.

How is CATI Conducted?

Conducting a CATI survey involves several steps:

Questionnaire Design: Creating a computerized questionnaire with necessary skip patterns, validations, and branching logic.
Interviewer Training: Training interviewers on how to use the CATI system and conduct the interviews effectively.
Data Collection: Interviewers conduct telephone interviews, entering responses directly into the computer system.
Data Validation: Real-time validation checks ensure data completeness and accuracy during the interview.
Data Analysis: Collected data is immediately available for analysis, reducing the time between data collection and reporting.

In conclusion, CATI (Computer-Assisted Telephone Interviewing) is a modern and efficient method for conducting telephone surveys. By leveraging technology, it enhances data accuracy, reduces errors, and speeds up the data collection process.
