Consent to Participate in a Research Study

Sociosexuality F12 Part 1

 

Introduction

You are being asked to participate in a research study that is being done by researchers from Oakland University. This study is being done by Guilherme Lopes (graduate student), under the direction of supervising faculty member Dr. Todd Shackelford (Professor of Psychology), the research Faculty Advisor for this project. The purpose of this Informed Consent is to let you know more about the study so you can decide whether to volunteer for the study or not.  Please read the form carefully. You may ask questions about why the research is being done, what you will be asked to do, the possible risks and benefits, your rights as a volunteer, and anything else about the research or this form that is not clear. You may talk with your friends and family about this research study before making your decision. When all your questions have been answered, you can decide if you want to be in this study. This process is called ‘informed consent.’ If you decide to participate, your participation will indicate that you have read this Informed Consent and that you understand what it says. If you decide to participate, you will be asked to sign this form and will receive a copy of this form.

 

Why is this study being done?

The present study is designed to examine the sexual behavior of heterosexual men, in order to determine if human males engage in sperm competition in a manner that is similar to other species. More specifically, we will be analyzing the semen that males produce when masturbating under different conditions (i.e., imagining different sexual scenarios). The purpose (s) of this research study is (are) to guide future research concerning male sexual behavior.

 

Who can participate in this study?
You are being asked to participate in the study because you are a sexually active, heterosexual man between the ages of 18 and 35 years who has been in a committed romantic relationship for at least three months with a female partner who is also between the ages of 18 and 35. Students from Oakland University are eligible to participate but participation is not limited to these students. Because we are analyzing men’s semen quality, men who are receiving fertility treatment or who have received a vasectomy are excluded from this study.

 

Who is sponsoring this study?

None

 

Where is this study being done?

Oakland University campus in Rochester, MI.

 

What procedures are involved with this study?

If you agree to take part in this research study, you will be asked to participate in the following procedures:

 

Session 1 – 90 minutes*

·         Watch Orientation Video

·         Sign consent

·         Complete various questionnaires concerning your sexual behavior (e.g., how long since the last time you had sex?), relationship satisfaction, and personality

·         Physiological measures are taken (e.g., height, weight, grip strength using a device called a dynamometer (a hand held device that you squeeze to see how strong your hand grip is), head circumference using a measuring tape, the circumference of your shoulders and your hips using a measuring tape).

·         Provide a saliva sample by spitting into a plastic pharmaceutical tube through a clean, disposable straw. We will use your saliva sample to measure your hormone levels.

·         The researchers will use a microphone to record your voice while you say aloud each vowel (“a”, “e”, “i”, “o”, and “u”).  Your voice recording will be rated by a third party panel (300 men and 300 women) that the researchers will recruit from online sources. The researchers will use a software program to measure the vocal pitch of your voice recordings.  (Note: You may choose not to submit your voice recording, but you can still participate in all other aspects of the study. You will not be penalized if you choose not to submit your voice recording).

·         The researchers will also take a digital face photograph of you.  Your photo will be rated by a third party panel (300 men and 300 women) that the researchers will recruit from online sources.  (Note: You may choose not to submit your face photo, but you can still participate in all other aspects of the study. You will not be penalized if you choose not to submit your face photo).

·         The researcher reviews the procedures regarding the production and transportation of semen.

·         Schedule Sessions 2 and 3: Both Sessions 2 and 3 will occur within 14 days of Session 1. Session 3 will occur at least two days after Session 2. Participants who fail to complete Sessions 2 and 3 within 14 days of Session 1 are excluded from the study.

·         You will be compensated $25 at the end of Session 1.

 

Prior to arriving to Session 2

·         Measure testicular volume at home using instructions and measurement tools (i.e., calipers) that we will provide. To be clear, this measurement will be conducted by you in the privacy of your own home (or other location of your choosing).

·         Masturbate at home while imagining one of the scenarios

·         Bring semen sample to lab within 60 minutes; call Guilherme Lopes if can’t get to lab in 60 minutes

 

Session 2 - 30 minutes*

·         Deliver semen sample

·         Complete Session 2 questionnaire

·         You will be compensated $25 at the end of Session 2.

 

Prior to arriving to Session 3

·         Measure testicular volume at home using instructions and measurement tools (i.e., calipers) that we will provide. To be clear, this measurement will be conducted by you in the privacy of your own home (or other location of your choosing).

·         Masturbate at home while imagining the other scenario

·         Bring semen sample to lab within 60 minutes; call Guilherme Lopes if can’t get to lab in 60 minutes

 

*Session 3 - 30 minutes*

·         Deliver semen sample

·         Complete Session 3 questionnaire

·         You will be compensated $25 at the end of Session 3.

 

*For Sessions 2 and 3: You will be asked to schedule your sessions 2 and 3 within 14 days of the first laboratory session and deliver your samples to the laboratory. To be clear, these other sessions will be the times when you will bring your semen samples to the laboratory so these sessions should be scheduled at times that will allow you to collect the samples in close proximity to the scheduled laboratory session (i.e., within 60 minutes). If issues arise that prevent you from bringing your sample to the laboratory at the arranged time, then you can simply reschedule your appointment by calling Guilherme Lopes (248-370-4857). You will collect your samples at home (or another private place of your choosing) and do your best to transport these samples to our laboratory within one hour of ejaculation. For each sample, you will be asked to masturbate while imagining a different scenario concerning yourself and your romantic partner. After providing each sample, you will be asked to complete some basic information (e.g., how long has it been since you had sex with your partner?). We anticipate that it will take you no more than 30 minutes to drop-off your samples and complete the questionnaire for each session. To be clear, these estimated times do not include travel time to (or from) the laboratory or the time spent masturbating before traveling to the laboratory. If you successfully complete all phases of the study, then you will receive $75. If you fail to schedule and attend the appropriate laboratory sessions within 14 days, then you will be excluded from the study.

 

Due to the fact that we will ask you to abstain from sexual activity for at least 48 hours prior to each session, we strongly encourage you to inform your romantic partner about your involvement in this study.

 

After you submit your semen samples to the laboratory, the researchers will assess your semen quality (e.g., sperm number, sperm concentration) using an automated semen analysis device. Additionally, the researchers may mix your semen with the semen from another man and investigate the interaction between the semen samples under a microscope. We will retain your semen for up to 48 hours to complete semen mixing procedures. Following these procedures, specimens and all disposable materials (e.g., fluorescent dyes, microscope slides, test tubes, pipettes) will be discarded immediately in the proper receptacle. Materials that come into contact with the specimen will be discarded in a clearly-marked red biohazard bag.

 

After collection of all data

 

Face photo and voice recording are rated by third party panelists.

Your face photo and voice recording will be retained for a third party panel (300 men and 300 women) to rate your face photo and voice recording on various dimensions (face: attractiveness, masculinity/femininity, maturity, symmetry, intelligence, dominance, aggressiveness, dominance, perceived age; voice: attractiveness, masculinity/femininity, maturity, intelligence, dominance, aggressiveness, dominance, perceived age). The third party panelists will be recruited from online sources (e.g., Facebook, the researchers’ personal websites), and all the ratings will be performed entirely online. There is a possibility that local community members or Oakland University students might participate in that study, and so some of those participants may recognize individuals depicted in the stimuli. However, it is important to note that participants of that online study will not know the conditions under which the face photos and voice recordings were obtained. After we secure third party ratings, we will destroy all identifying information, including your name, face photo, and voice recording.

 

How long will participation in this study last?

Session 1 will last approximately 90 minutes, Session 2 will last approximately 30 minutes, and Session 3 will last approximately 30 minutes. Sessions 2 and 3 will occur within 14 days of Session 1. Session 3 will occur at least 2 days after Session 2.

 

The researcher may stop your participation in this study at any time without your consent. For example, the researcher may stop your participation in this study if you fail to complete all three Sessions within 14 days. The Principal Investigator, Guilherme Lopes, will contact you via phone or email (depending on the method in which you initiated contact with the research lab) to inform you that you have been removed from the study.

 

How many people will be participating in this study?

100 men

 

What are the risks, side effects or discomforts that can be expected from participating in this study?

By taking part in this study, you may be at risk for the following:

Participation in this study may be stressful for you because you will be asked to report your sexual behavior and provide semen samples to the researchers. If you feel upset or distressed as a result of your participation in this study, you may want to consider contacting the Oakland University Graham Health Center (248-370-2341), the Oakland University School of Education and Human Services Counseling Services (248-370-2633), or Oakland Family Services in Rochester Hills (866-903-8955). It is important that you contact the Principal Investigator (Guilherme Lopes, gslopes@oakland.edu), the Faculty Advisor (Dr. Todd Shackelford, shackelf@oakland.edu), and the Co-Investigators (Dr. Virgil Zeigler-Hill, zeiglerh@oakland.edu; Dr. Lisa Welling, welling@oakland.edu) if you are upset by your participation in the present study. To minimize the risk that someone else may gain access to your information, all of your responses will be kept in the strictest of confidence and will not be available to anyone other than the researchers conducting the study. After you receive payment for participation, we will destroy your identifying information, with the exception of your face photo and voice recording, which we will retain for use as stimuli for the third party panelists to rate. After we complete the part of the study in which third party panelists rate your face photo and voice recording, we will destroy all identifying information, including your face photo and voice recording. To protect your identity, your name will be separated from the information you provide and replaced with a 3-digit participant identification number. The researchers will keep a master list linking your name with your 3-digit participant identification numbers until data collection is complete. This master list will be kept in a locked laboratory that is separate from the data on campus in a password-protected computer. This master list will be destroyed when data collection is complete. This master list is necessary for us to keep track of the samples that you will provide during the study and to arrange your payment. The researchers supervising the study (Drs. Shackelford, Zeigler-Hill, and Welling) and the graduate students conducting the laboratory sessions will be the only individuals who will have access to this information. The results of this study will be presented in aggregate form with no identifying information to ensure your confidentiality. That is, we will only analyze the data as a group and no identifying information will ever be released.

A breach of confidentiality is also a possible risk.  Breach of confidentiality means that it is possible that individuals not associated with this research may accidentally gain access to information that personally identifies participants.  Appropriate safeguards are set in place to minimize a breach of confidentiality (e.g. researcher’s office is secure and computers and external storage devices are password protected); but no researcher can ever guarantee that this sort of breach will not occur.

 

Are there any known benefits from taking part in this study?

There are no direct benefits to you for participating in this study.  However, the results of this study may benefit others in the future.

 

What are the alternatives to participation in this study?

You may choose not to participate in this study.

 

What are the costs of taking part in the study?

There is no cost to you for participating in this study.

 

What compensation is being provided for participation?

For taking part in this study, you will be paid for your time and inconvenience: You will be paid $75 for successfully completing all sessions of the present study. Specifically, you will be paid $25 at the end of each session. This amounts to $25 per session for 3 sessions. Session One will last approximately 90 minutes, Session Two will last approximately 30 minutes, and Session Three will last approximately 30 minutes. If you fail to schedule and attend the appropriate laboratory sessions within 14 days, then you will be excluded from the study but you will be paid $25 per session for the sessions that you have completed.

 

What are your rights if you participate in this study?

Your decision to participate in this study is voluntary. You may choose to leave the study at any time, or refuse to answer any questions that may be asked during the study. You will not lose any benefits to which you are otherwise entitled and your decision will not affect your present or future relationship with Oakland University, the researcher, or the Psychology department.  If you are a student or employee at Oakland University, your decision about participation will not affect your grades or employment status.
