This is my data set description and I need help, I put what I have so far but I am struggling on the dependent variable since there is no data for sti's they just have data for the answered questions:

Health researchers have identified a rise in contacting STIs (sexually transmitted infections) among young adults and are interested in understanding why.The researchers measured several variables related to condom use including: likelihood of using condoms in the future, previous use of condoms, perceived ability for self-control in sexual relationships, and perceived risk for contracting STIs.

Method

This study is looking to understand why there has been a rise in sexually transmitted infections. Participants were asked to answer 4 different questions and the results were analyzed.

Participants: Participants include 100 men and women ages ranging from 18-38. The mean age in this experiment is 24 years old and there is an equal amount of men and women.

Name of Independent Variable(s): Provide a description of all independent (or grouping) variables, including their levels. Each variable should be described separately and the name of each new variable should be indented and underlined.

Name of Dependent Variable:Provide a description of the dependent variable, including how it was operationalized.

Following the description of all your variables you should clearly state (in a sentence) the research question you intend to investigate.Next, you should say something along the lines of, "This research has the following hypotheses:

H_a: State the alternate hypothesis in BOTH conceptual and statistical form.

H₀: State the null hypothesis in BOTH conceptual and statistical form

I also need to know what spss analysis to complete
