Computer-assisted telephone surveys

In the computer-assisted telephone survey, participants are interviewed via telephone by a trained interviewer. BACES conducts the telephone survey using computers so that the interviewer can read out the questions and enter the answers directly into a computer programme. The particular advantage of a telephone survey is that additional or more in-depth information can be collected than in a written or online survey. Another advantage is that the population can be almost completely covered, since almost every household has a telephone connection. To avoid unwanted influence, BACES surveys are conducted exclusively by trained interviewers.

The implementation of a computer-assisted telephone survey by BACES includes the following services:

• Method consulting
• Questionnaire development and programming
• Preparation of sampling plans
• Sampling and administration
• Interviewing by trained interviewers under supervision
• Data cleaning and processing
• Coding of open questions
• Preparation of tables and presentations
• Preparation of survey reports
• Documentation of fieldwork
