Explain the difference between longitudinal, cross-sectional, and sequential designs, and note what their similarities are, as well
What will be an ideal response?
Student responses should include

-sequential designs are like a cross-sectional design that goes on for a short, rather than extended, period of time
-all three of these designs allow for the study of developmental trends in abnormal behavior
-a longitudinal design might result in a high attrition rate, while a cross-sectional design does not run this risk
-a cross-sectional design might retain more participants, but might contain cohort effects
-a sequential design attempts to take the best of what longitudinal and cross-sectional designs have to offer and avoid their risks
