Informed Consent


You are invited to participate in this study of relationships between twins and their twin's children. This 3-part study takes about 15 to 20 minutes to complete.

Your participation is strictly voluntary. All information collected is anonymous and confidential. Although an initial computer identifier code is collected when responses are entered, this information is subsequently stripped from all data analyses and erased. No identifying information about your individual answers will be divulged. All research records will be kept confidential to the extent provided by law.

Your decision concerning whether or not to participate will not affect your future relations with California State University, or your relations with your current educational institution or place of business in any way. If you decide to participate, you are free to discontinue participation at any time. By completing this questionnaire, you have provided your consent to participate.

The survey has been tested utilizing Netscape Navigator and Internet Explorer only. Please use either browser to complete the study, or make sure that your alternate is able to process CGI scripts.

A summary of results (based on group data only) will eventually be placed at this website.

If you have questions about the research, please call 657-278-2568 (Twin Studies Center). If you have questions about subjects' rights, please contact the Institutional Review Board (IRB) representative at CSUF: Ms. Lori Jennex, 657-278-7640.
