Welcome to "Relationships, Sexuality and Personality", a web-based study that examines the interplays between your personality and your  relationships. Before taking part in this study, please read the consent form below and click on the "I Agree" button at the bottom of the page if you understand the statements and freely consent to participate in the study.

This web-based study is designed to understand more deeply which persons prefer what type of relationships, ranging from brief sexual encounters to ever-lasting committed long-term relationships. This international study is being conducted by Dr. Sascha Schwarz from the University of Wuppertal (Germany), and it has been approved by the local Ethics Commitee. No deception is involved, and the study involves no more than minimal risk to participants (i.e., the level of risk encountered in daily life).

Participation in the study typically takes 30 minutes and is strictly anonymous. Participants answer a series of questions about their personality and their sexual experiences.

All responses are treated as confidential, and in no case will responses from individual participants be identified. Rather, all data will be pooled and published in aggregate form only. Participants should be aware, however, that the study is not run from a "secure" https server of the kind typically used to handle credit card transactions, so there is a small possibility that responses could be viewed by unauthorized third parties (e.g., computer hackers).

Many individuals find participation in this study enjoyable, and no adverse reactions have been reported thus far. Participation is voluntary, and participants may withdraw from the study at any time.

At the end of this questionnaire, every participant receives immediately a graphical feedback from his/her individual personality profile, based on one of the most famous personality tests included in this study.

If participants have further questions about this study or their rights, or if they wish to lodge a complaint or concern, they may contact the principal investigator, Dr. Sascha Schwarz, at +49-202-439-2323 or Prof. Dr. Wolfgang Spiegel, the head of the Ethics Commitee from the University of Wuppertal at +49-202-439-2225.
