Influence of scale administrator on employee attitude responses.

"The results gave support to the following hypotheses: 1. A threat to employees' feelings of anonymity results in their responding more favorably to an attitude survey than employees not so threatened. 2. A threat to anonymity results in differential amounts of response distortion depending upon the content of different items comprising the questionnaire. 3. Employees feeling a threat to anonymity tend to give fewer and shorter responses to open-end questions than employees not so threatened." (PsycINFO Database Record (c) 2010 APA, all rights reserved)
