Based on information provided by 149 runaways staying in a Canadian shelter, the authors developed a model that explains repititious running away as the result of youths' cognitive confusion and unrealistic beliefs. The majority of the youths, who had run away an average of 8.9 times, felt that the events that led them to run away were unpredictable, yet 54 percent blamed only themselves for what happened. The paper describes the pathways, cycles, and outcomes of running away; analyzes the relationship between the youths' experiences with prostitution, delinquency, and sexual and physical abuse and the length of time they had been away from home; summarizes the youths' reasons for running away; compares the beliefs of runaways with and without a history of sexual abuse; and discusses interventions.
