The Life Events Scale is a series of major life events adapted from Dodge, Pettit, & Bates (1994). Parents are read a series of 19 major life events (such as a move, birth of a child, divorce, death of a close family member, etc.) and are asked if that event has occured in the last year, indicating either yes or no.
