Studying authoritarian parenting styles

Imagine you are a psychologist interested in studying how authoritarian parenting styles (parents who raise children in a strict up-bringing) influence college students’ performance in their classes. What independent variables would you select or manipulate? What dependent variables would you choose? What type of study would you use?

(To earn full points, your answer should clearly identify 1 or more independent variable(s), 1 or more dependent variable(s), and a brief description of the type of study, as well as a justification as to why you chose that type of study.)
