CATI vs Digital surveys

What are CATI surveys?

CATI is an abbreviation for “Computer-Assisted Telephone Interviewing.” It refers to a process of conducting surveys and data collection using telephone interviews and computer software. CATI surveys involve professional interviewers calling respondents and guiding them through the survey questionnaire using a computer programme.

Here’s how CATI surveys typically work:

  • Questionnaire Design
  • Sampling
  • Phone Calls
  • Data Entry
  • Real-time Data Management
  • Data Analysis

Example

Here’s a concise example of a Computer-Assisted Telephone Interviewing (CATI) survey:

Scenario: Customer Satisfaction Survey

A telecommunications company wants to assess customer satisfaction with their recent service experiences. They use CATI to conduct a quick survey.

  1. Questionnaire Design: The company designs a questionnaire with questions about call quality, customer service responsiveness, and overall satisfaction.
  2. Sampling: They randomly select phone numbers from their customer database.
  3. Phone Calls: Trained interviewers call the selected customers and introduce the survey. If the customer agrees to participate, the interviewer proceeds.
  4. CATI Software: Using a CATI software tool, the interviewer reads out the questions from the questionnaire while inputting the customer’s responses directly into the system.
  5. Real-time Validation: The CATI software helps the interviewer by skipping irrelevant questions based on previous responses and highlighting potential errors or inconsistencies.
  6. Data Collection: As the survey progresses, the software compiles the responses and ensures the data is accurately entered.

Advantages

CATI surveys offer several advantages:

  • Efficiency: The use of computer software streamlines the survey process, making data collection and management more efficient compared to traditional paper-based surveys.
  • Data Quality: Real-time validation and consistency checks can help improve the accuracy and quality of the collected data.

Differences Between CATI and Digital surveys

  Key Differences CATI Digital surveys
1.        Method of Data Collection: CATI surveys involve conducting interviews over the phone. Trained interviewers use a computer program to guide them through a structured questionnaire while interacting with respondents via telephone calls.

 

Digital surveys are conducted online, typically through web-based forms, email invitations, social media, or mobile applications. Respondents fill out the survey on their own using a computer or mobile device.

 

2.        Communication Medium:

.

 

CATI surveys involve direct verbal communication between interviewers and respondents over the phone. Interviewers ask questions and record responses in real-time.

 

Digital surveys rely on written communication. Respondents read and answer questions in text format through the online survey interface
3.        Mode of Administration: Interviews are administered by interviewers who read the survey questions aloud and input responses. The CATI software guides the interview process.

 

Respondents self-administer the survey without direct involvement from interviewers. They read and respond to questions at their own pace.

 

4.        Interaction and Engagement:

.

 

The interviewer’s tone, manner, and verbal cues can impact respondent engagement and responses. Interviewers can provide clarifications and encourage participation Interaction is limited to the written survey content. There are no direct verbal cues, and respondents might interpret questions differently without real-time clarification.

 

5.        Data Validation:

 

 

CATI software can include real-time validation checks, ensuring logical responses and preventing inconsistencies during the interview process  Some survey platforms include built-in validation to ensure accurate and consistent responses, but respondents might still provide incomplete or inaccurate information
6.         Reach and Sample:

 

 

Reach can be limited to individuals with accessible phone lines. There might be biases based on phone ownership and willingness to participate in phone surveys Digital surveys can reach a wider audience, including those with internet access, but might exclude individuals who are not comfortable with technology or lack online access

 

7.        Anonymity:

 

Respondents might be less comfortable providing sensitive information over the phone due to privacy concerns.

 

Respondents have the option of remaining anonymous, potentially leading to more honest and open responses
8.        Cost and Efficiency:

 

Can be more time-consuming and expensive due to the need for trained interviewers and phone call expenses.

 

 Generally cost-effective and efficient, with no need for interviewer involvement or phone call expenses.
