What is computer assisted telephone interviewing?

Computer assisted telephone interviewing (CATI) is a research method that combines telephone surveys with computer software to facilitate and streamline the data collection process. It involves the use of specialized computer programs that guide interviewers through the survey questions, capture responses, and manage the overall survey administration.

CATI systems offer numerous advantages over traditional telephone survey methods, such as increased interviewer efficiency and survey accuracy. The integration of computer technology enables real-time data validation, automatic skip patterns, and remote monitoring of interviewers, ensuring that the data collected is accurate and consistent.

How does computer assisted telephone interviewing work?

CATI works by connecting interviewers with respondents through telephone calls. The computer software provides a scripted questionnaire that guides the interviewer through each question and response option. The software typically includes built-in logic checks and skips patterns, ensuring that the questions are asked in a consistent manner and relevant follow-up questions are asked based on the respondent’s answers.

What are the benefits of computer assisted telephone interviewing?

Computer assisted telephone interviewing offers several benefits, including:

1. Increased efficiency: The use of CATI software simplifies the interviewing process, allowing interviewers to focus more on the conversation with the respondent rather than manually documenting responses.

2. Real-time data validation: CATI software can provide immediate feedback to interviewers if they input a response that violates any predefined rules or constraints, improving data quality.

3. Flexible survey administration: CATI systems enable remote monitoring and supervision of interviewers, ensuring the quality and consistency of data collection. This flexibility allows researchers to conduct surveys across different geographic locations.

4. Automatic skip patterns: CATI software automatically skips irrelevant questions based on the respondent’s answers, saving time and minimizing the chances of errors.

5. Lower costs: CATI eliminates the need for manual data entry and data cleaning, reducing operational costs and increasing the speed at which data can be analyzed.

6. Quick survey deployment: CATI systems allow for rapid survey deployment and data collection, making it a suitable method for time-sensitive research projects.

What types of surveys use computer assisted telephone interviewing?

CATI can be used for various survey types, including market research surveys, customer satisfaction surveys, political polls, social research, and public opinion surveys. CATI is particularly useful when it is necessary to collect large amounts of data from diverse populations in a short period.

Are CATI surveys more accurate than traditional telephone surveys?

CATI surveys generally provide higher accuracy compared to traditional telephone surveys. The use of scripting and skip patterns reduces interviewer bias and ensures that questions are consistently asked, minimizing the chances of errors. Additionally, real-time data validation features in CATI software help prevent data entry mistakes.

Can CATI be used for qualitative research?

While CATI is primarily used for quantitative research, it can also be adapted for qualitative research. CATI software allows for open-ended responses and the ability to record and transcribe respondents’ answers. However, it is important to note that CATI may not offer the same depth and richness of data as other qualitative research methods.

What are the limitations of computer assisted telephone interviewing?

Some limitations of CATI include:

1. Sampling bias: CATI relies on telephone directories or random digit dialing, which may exclude certain demographic groups without phone access, leading to potential sampling bias.

2. Limited respondent engagement: The absence of face-to-face interaction may result in lower respondent engagement and the potential for response bias.

3. Non-response bias: CATI surveys may suffer from non-response bias if certain individuals refuse to participate or cannot be reached.

4. Limited question complexity: Due to the constraint of verbal communication, CATI surveys may not be suitable for complex questionnaires that require visual aids or multimedia elements.

How is data stored and analyzed in CATI?

Data collected through CATI surveys is digitally stored within the CATI software or transferred to a central database for further analysis. The software typically offers data export options in various formats (e.g., CSV, Excel) for statistical analysis using specialized software like SPSS or Excel.

Can CATI be combined with other research methods?

Yes, CATI can be combined with other research methods to enhance data collection. For example, CATI surveys can be followed up with face-to-face or online surveys to gather more in-depth information or validate findings.

Are there any legal considerations when conducting CATI surveys?

When conducting CATI surveys, researchers must comply with applicable legal and ethical considerations, such as obtaining informed consent from respondents, ensuring data privacy and confidentiality, and following any relevant regulations or guidelines.

What are some popular CATI software options?

Some popular CATI software options include Voxco, Sawtooth Software, Quancept, Survey System, and Nebu Dub InterViewer, among others. The choice of software depends on specific research requirements and budget constraints.

Are CATI surveys suitable for international research?

CATI surveys can be adapted for international research, but specific considerations need to be taken into account. These include language translation, cultural sensitivity, time zone differences, and compliance with local regulations or norms.
