The improvement of user satisfaction with a product is the goal of all product-oriented businesses. Examining the user experience is essential to this process, which evaluates the hedonistic, aesthetic, and pragmatic properties of a product. Also, it studies the products’ usability, the user’s feelings, emotions, and desires before, after, and while using the product. Usability and user experience questionnaires are a popular method to collect user experience data. Here, these have been reviewed regarding their general characteristics, constituent factors, and their items’ content. The analysis of the items was based on the Component model of User Experience (CUE) by Thüring and Mahlke. It reveals shortcomings in usability questionnaires, such as a lack of consideration of hedonistic and aesthetic properties. Based on these findings, we propose a new questionnaire design, an extended model of the Post-Study System Usability Questionnaire (PSSUQ). Twelve new items and two new factors have increased to this questionnaire, examining Experiential Hedonic and Experiential Aesthetics qualities. The evaluation of the Extended-PSSUQ has been done by surveying the Mattermost software users in Otto-von-Guericke-University. All factors’ reliability results are above 0.8, indicating good results as standard usability and user experience questionnaire. Also, the concurrent validity of the overall Extended-PSSUQ correlated positively with the sum of the After Scenario Questionnaire (ASQ) ratings (r(21) = 0.624, p = 0.003).
