More generally, one key concern with questionnaires is that there may contain quite large measurement errors ( [10] ). These errors can be random or systematic. Random errors are caused by unintended mistakes by respondents, interviewers and/or coders. Systematic error can occur if there is a systematic reaction of the respondents to the scale used to formulate the survey question. Thus, the exact formulation of a survey question and its scale are crucial, since they affect the level of measurement error ( [11] ). Different tools are available for the researchers to help them decide about this exact formulation of their questions, for instance estimating the quality of a question using MTMM experiments or predicting this quality using the Survey Quality Predictor software ( SQP ). This information about the quality can also be used in order to correct for measurement errors ( [12] [13] )
