Project Title: An investigation into the effect of Digit Ratio on prevailing Sexual Attitudes and Behaviour within the male student population


1. Invitation and brief summary

You are invited to take part in a research study undertaken by Maisie Andrew as credit for an MSc Psychology Conversion Thesis Project. Before you decide to participate it is important to read the following information for you to understand what will be required from you and why the research is being done.


2. What is the purpose of the project?

This study is investigating the effect of digit ratio on Sexual attitudes and  behaviour within the male student population. Digit ratio is the calculated length between for 1st (index finger) and fourth (ring finger) digit and is a marker of prenatal testosterone i.e the levels of testosterone you were exposed to in the womb. The purpose of this study is to investigate whether digit ratio has any effect on sexual attitudes and behaviour within the male student population.


3. Who is conducting the project?

The thesis project is being conducted as credit for an Msc Psychology Conversion at Leeds Trinity University. The project will be carried out by Maisie Andrew, under the supervision of Dr James Jackson, a Senior Lecturer in Psychology, School of Social and Behavioural Sciences, Leeds Trinity University.


4. What does the project involve?

You will be asked to complete two short online questionnaires. The questionnaires each measure different attitudes towards sex, as well as questions regarding your sexual behaviour. Due to the sensitive nature of these questions, anything you are not comfortable with may be skipped. The questionnaires should take around 5 minutes each, and the whole study should take around 20 minutes to complete. You will then be asked to provide a scanned copy of your right and left hand using a desktop scanner. This is to allow for the measurement of your finger lengths to obtain your digit ratio. You will be asked to remove all of your rings and draw small marks on the basal creases of your first and fourth finger using a ballpoint pen, as seen in the image below. You should then place your hands palm down and flat on the glass to ensure fingers are equally extended so the scanner can capture a clear picture of the full hand. The image below is an example photocopy used within Pintzka, Evensmoen, Lehn, & Håberg (2016) study, and highlights what your scanned image should look like. This process should take you no longer than 10 minutes. PLEASE EMAIL YOUR SCANNED IMAGE TO ALONG WITH YOUR UNQIUE PARTICIPANT CODE.

5. Can I withdraw from the project?

As this study is entirely voluntary, you are under no obligation to provide consent. Moreover if you do provide consent you are free to withdraw from the study at any point, whether that is during the study itself or after the data has been collected. If you wish to withdraw, both your digit ratio score and your responses to the two questionnaire scales will be destroyed immediately and not included in the results. However you will only have 10 working days once the data is collected to withdraw yourself from the study. To withdraw from the study please contact either the principle researcher, or the researcher supervisor, who’s contact details are included at the bottom of this sheet. You will need to provide your participant code (Initial/birth day/birth year eg MA2406) so the researcher can correctly identify your data.


6. How will the data be dealt with and who will see the results?

Participation within this study is entirely confidential, no information about your participation will be shared by the researcher or supervisor. Moreover, all data provided by participants including digit ratio scores, and questionnaire responses will be completely anonymised by unique participant codes. The results will be presented as part of a thesis project, in which only the researcher and supervisor having access. All data, including digit ratio scores, consent forms and questionnaire responses will be stored on a secure server at Leeds Trinity University for a period of 10 years. The anonymised data may be used by the researcher and supervisor to seek publication if the findings are recognised as being of academic interest.
