Meta Analysis

combining information from multiple studies that already existed

Longitudinal

studying same participants over a long period of time

Cross Sectional

collecting data once on multiple age groups

Operational Definition

Informed Assent

parental authorization for those 12-18

Protection from Harm

Confidentiality

nothing traced back to participants

Debriefing

told about the true nature of the study after it is completed

Generalizability
