Retrospective - study people with a disorder by collecting information about their lives before they became sick.  Problem is faulty and selective memory, bias on the part of the person and the researcher.  Prospective - find people with high risk of developing a disorder before they have it, measure variables ahead of time and track the person to see who develops the disorder.  Problem - can't know how may will develop the disorder - small sample size
