Final answer:
In-office interviewing requires interviewers to navigate around gatekeepers, which are individuals in professional settings who control access to information or people. CAPI and CATI, being computerized forms of data collection, usually do not face this issue as they directly contact respondents.
Step-by-step explanation:
The data collection mode that requires interviewers to navigate around gatekeepers is in-office interviewing. Gatekeepers are individuals who control access to people or information, often found in professional or organizational settings. When conducting in-office interviews, interviewers might encounter administrative assistants, receptionists, or other personnel who act as gatekeepers. It is the interviewer's task to negotiate with these gatekeepers to reach potential interviewees. This can be especially challenging in business or corporate environments where access to certain individuals is tightly controlled.
Unlike in-office interviewing, Computer-assisted personal interviewing (CAPI) and computer-assisted telephone interviewing (CATI) are modes of data collection that leverage technology and typically do not involve navigating gatekeepers in the same way as in-office interviews do. These methods involve direct interaction with the respondent using a computer or telephone, often bypassing the need for intermediate contacts.
