Participant information

Project Title: The Dark Tetrad and mating effort as predictors of propensity for sexual coaxing and coercion across different potential victim-perpetrator relationships.

Researcher: Roksana Koscielska

Supervisor: Dr Vincent Egan


This study has been approved by the Nottingham University Institutional Review Board 

Ethics Reference Number: 233


This is an invitation to take part in a research study about personality and use of sexual strategies. The term “sexual strategies” refers to different tactics that people might use to gain sexual contact when the other partner is unwilling to participate. This includes behaviours such as using humour, saying sweet things, threatening to leave, and using blackmail or physical restraint. This information is designed to tell you what the study will involve.

Your participation is voluntary, and you may change your mind about being involved, or decline to answer a particular question at any time, and without giving a reason. You are free to withdraw at any point before or during the study. However, because this is an anonymous questionnaire, once you have finished the questionnaire and submitted your answers it is not possible to withdraw the data.

What is the project about?

The current study aims to investigate personality in relation to use of sexual strategies. In particular, the study looks at the use of sexual strategies in imagined scenarios involving an unwilling partner.

Who is being asked to take part?

Because the study is investigating use of sexual tactics, individuals aged 18 and above are being asked to take part in the study. This involves males and females who are heterosexual, homosexual, or bisexual.

What will I be asked to do?

It should take about 30 minutes to take part in this study. You will be asked to complete a 3-part questionnaire. The questionnaire is completely anonymous so, please, be as truthful as you can when answering questions. All questions and scenarios used in the current study have been developed and validated in previous and already published research. In the first part, you will be asked to provide information such as your age, sexual orientation, sexual experience, education, employment, criminality, and country of residence. In the second part of the questionnaire, you will be asked to answer 106 questions relating to your personality and attitudes. Next, you will be asked to indicate which tactics you would use to obtain sexual contact in three imagined scenarios. These will involve a neighbour, an ex-partner, and a current romantic partner. 

Please note that some of the questions in the study may be upsetting. You can easily exit the survey at any point if you decide that you do not wish to continue anymore. This can be done by closing the browser window. Alternatively, at the end of each page you will find a sentence which states “I do not wish to go further. Please take me to the end of the survey”. If you select the button next to that sentence, the survey will automatically take you to the end page on which you will find more information and details of helplines and services which can provide support.

Will the research be of any personal benefit to me?

Although the research will not provide you with any personal benefits, it will greatly contribute to the field of psychology.

What will happen to the information I provide?

All data provided will be completely anonymous and treated as confidential. Only the researcher (Roksana Koscielska) and the project supervisor (Dr Vincent Egan) will have access to the data. All data will be stored on a personal, password-protected laptop of the researcher.

What will you do with the data?

The data will be analysed and used as part of a dissertation project by 1st of August 2017. You can contact Roksana Koscielska after this date, if you would like to learn about the results of the study.


If you have any questions or concerns, please do not hesitate to ask. We can be contacted before and after your participation at the above addresses.
