Employee Survey

There advantages and disadvantages to conducting web or electronic surveys as opposed to traditional survey modes such as personal interviewing, telephone and mail.  One of the advantages of an online survey design is a possible reduction of what is known as social desirability bias. 

Social desirability bias occurs when survey respondents offer responses that portray them in a positive or more favorable manner to others. 

When a face-to-face interviewer asks personal or sensitive questions respondents feel have a “good answer” and a “bad answer” (such as criminal behavior), they may underreport bad behavior and overreport good behavior, for example.  While this bias may be reduced in online surveys due to the absence of an interviewer, there are topics that may produce invalid or unreliable data, regardless of survey mode.  This is something to consider before finalizing your online questionnaire design or web survey forms.
