The document discusses substance abuse in girls and women from a developmental theory perspective. It explores how developmental theories seek to describe psychological, emotional, and perceptual changes throughout the lifespan and identify key stages and changes. For example, the transition to college involves defining oneself and exploring culture and intellect, which can expose students to increased substance use opportunities. The document asks the reader to examine how developmental theories may account for substance abuse in girls and women by researching use of a specific substance, considering the immediate and long-term effects of abuse, and explaining how theory accounts for abuse and a theory-based intervention.
