Which aspect of questionnaires can make them impersonal?

The aspect of questionnaires that can make them impersonal is the lack of verbal interaction. This means that respondents engage with the questionnaire in a solitary manner, without the presence of an interviewer or facilitator who might typically guide the conversation or provide clarification on questions. The absence of personal interaction can lead to a sense of distance between the researcher and the participants, as individuals can feel like they are simply providing answers to a set of predetermined questions rather than engaging in a dialogue. This can diminish the emotional connection and contextual understanding that often accompany face-to-face interactions, making the experience feel more mechanical and less personal.

While other factors can impact the personal nature of questionnaires, they don't inherently contribute to the same degree of impersonality. For instance, a structured format or the nature of anonymity may influence how responses are given or perceived, but these aspects do not directly address the human element of interaction. Similarly, the requirement to answer all questions can enhance the rigor of data collection but does not inherently affect the personal engagement experienced by the respondent.
