The presented study deals with the usability of the web-based questionnaires. On a sample of 130 university students (2 paired groups by 65 persons each) psychometric characteristics (means, variabilities, reliabilities, and relationships among variables) of paper/pencil and the web-based forms of three selected methods - The Oxford Happiness Questionnaire; Satisfaction With Life Scale; Extraversion Scale from the NEO-FFI - were evaluated. It was confirmed that these characteristics were not affected by the form of administration.
