These represent personality domains associated with aspects of power, love, work, affect and intellect and are frequently labeled Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness
The purpose of this study is to examine the correlational structure of items used in many personality inventories. In addition, by allowing the public to participate in this web-based data collection project we hope to increase public knowledge about science-based models of personality. This questionnaire will compare your answers to those of prior respondents and give you an estimate of your level on each of several broad personality dimensions. These domains represent normal differences in personality that are typically known by friends and close colleagues. It will also estimate your level on a range of more narrow personality domains (see the content listed on this website for more details).
This personality assessment will not reveal any secret information about you, nor will it assess any serious psychological problems. The report 
is designed to be objective, not necessarily pleasing or flattering. Because you will be given a limited number of items, sampled from a broad pool of items, your scores will be sensitive to errors of measurement and will not necessarily agree with measures of the same traits using other items. If people who know you well disagree with the results of this assessment, then the assessment results are probably wrong. If you answer the survey carelessly or intentionally try to distort the results, then the results will be incorrect.
For more information about personality theory and research, please consult the Personality Project. Other online tests are discussed there, as well as links to reviews of current literature in personality assessment.
The questions are not timed and you may take as long as you want on every item
Procedures: As a participant in this study, you will be asked to indicate your level of agreement to many statements. Most of these statements are taken from the International Personality Item Pool. Some exploratory items are taken from other sources. This questionnaire typically takes about 20 minutes to complete, although you might finish it in less time or you might take more time. You do not need to answer every item, but the results will be less accurate if you skip items. If at any time, you decide to stop, you are welcome to do so. When you submit your answers, you will be given a page that shows the best interpretation of your responses and how your results compare to others. The report generated from your participation is designed to produce estimates that are as accurate as possible, but not necessarily flattering. Again, if knowledgeable acquaintances disagree with the results of this survey, then the survey’s results are probably inaccurate.
Confidentiality: Your results are anonymous. We are not asking nor recording your name or contact information, nor are we collecting any information that is directly identifying. We do not use “cookies” or any other tracking techniques that persist after you have left this website.
Data Sharing: None of the data collected through this project are used commercially. We do not sell or trade data with third-party organizations. Results of this study may be used for teaching, research, publications, or presentations at scientific meetings. For the sake of scientific transparency, these data are placed into the public domain at regular intervals (every couple of years) in hopes that other researchers will attempt to reproduce or extend our findings. Before placing any data into the public domain, any variables that could be used to re-identify individual participants (either independently or in combination) are removed from the data to the best of our ability. Please note that re-identification remains a possibility, though we believe that the motivation for doing so is low. We encourage concerned participants to skip any items that they are uncomfortable answering.
