Online data collection could advantageously replace paper-and-pencil questionnaires in epidemiological studies by reducing the logistic burden, the cost and the duration of data processing. However, there is a need for studies comparing these new instruments to traditional ones. Our objective was to compare the web-based version of the NutriNet-Santé self-administered anthropometric questionnaire to the paper-based version. The questionnaire included 17 questions divided into subquestions (55 variables in all) dealing with height, weight, hip and waist circumferences, weight history, restrictive diet and weight self-perception. Both versions of the questionnaire were filled out by 147 volunteers (paper version first, N = 76, or web-based version first, N = 71) participating in the SU.VI.MAX (''Supplémentation en VItamines Minéraux et AntioXydants'') cohort (age-range: 49-75 years; men: 46.3%). At the end of the test, subjects filled in a ''satisfaction'' questionnaire giving their opinions and feelings about each version. Agreement was assessed by intraclass correlation coefficients (ICCs) and kappas. We also quantified the number of errors inherent in the paper version.Agreement between the two versions was high. ICCs ranged from 0.86 to 1.00. Kappas ranged from 0.69 to 1.00 for comparable variables. A total of 82 data entry mistakes (1.5% of total entries), 60 missing values (1.1%), 57 inconsistent values (1.1%) and 3 abnormal values (0.1%) were counted in the paper version (non-existent in the webbased version due to integrated controls). The web-based version was preferred by 92.2% of users. In conclusion, the quality of information provided by the web-based anthropometric questionnaire used in the NutriNet-Santé Study was equal to, or better than, that of the paper version, with substantial logistic and cost advantages.

“…Thirdly, it is easier to reach respondents worldwide (Evans & Mathur, 2005). Internet reduces the time and distance between people, and makes communication more efficient (Ekman & Litton, 2007). In addition, online questionnaires may be more convenient to respondent as they can answer when suitable for them.…”

Projective techniques are used in psychology and consumer research to provide information about individuals' motivations, thoughts, and feelings. This paper reviews the use of projective techniques in marketing research and user experience research and discusses their potential role in understanding users, their needs and values, and evaluating user experience in practical product development contexts. A projective technique called sentence completion is evaluated through three case studies. Sentence completion produces qualitative data about users' views in a structured form. The results are less time-consuming to analyze than interview results. Compared to quantitative methods such as AttrakDiff, the results are more time consuming to analyze, but more information is retrieved on negative feelings. The results show that sentence completion is useful in understanding users' perceptions and that the technique can be used to complement other methods. Sentence completion can also be used online to reach wider user groups.
