Validating the school culture survey
Most cellphones also have caller identification or other screening devices that allow people to see the number that is calling before deciding to answer.
People also differ considerably in how they use their cellphones (e.g., whether they are turned on all the time or used only during work hours or for emergencies).
The choice of mode can affect who can be interviewed in the survey, the availability of an effective way to sample people in the population, how people can be contacted and selected to be respondents, and who responds to the survey.
In addition, factors related to the mode, such as the presence of an interviewer and whether information is communicated aurally or visually, can influence how people respond.
These payments, as well as the additional time necessary for interviewers to collect contact information in order to reimburse respondents, add to the cost of conducting cellphone surveys.Legal restrictions on the use of cellphones while driving, as well as concerns about safety, also have raised the issue of whether people should be responding to surveys on their cellphones while driving.In addition, people often talk on their cellphones in more open places where they may have less privacy; this may affect how they respond to survey questions, especially those that cover more sensitive topics.Response rates are typically lower for cellphone surveys than for landline surveys.In terms of data quality, some researchers have suggested that respondents may be more distracted during a cellphone interview, but our research has not found substantive differences in the quality of responses between landline and cellphone interviews.
