Reabuse was determined by matching sample names against information in a centralized reporting system. Reabuse was studied across demographic and socioeconomic variables, vulnerability days, initial and subsequent types of abuse, and other considerations. Results revealed that at the end of the 61- to 72-month followup period, the incidence of reabuse was 16.8 percent. The greatest risk of reabuse occurred during the first 2 years following an initial discharge diagnosis of maltreatment. Although no particular initial maltreatment diagnosis was a statistically significant predictor of the likelihood or type of reabuse, neglect was the most frequent type of reabuse. Children experiencing reabuse were also more likely than nonabused children to live in public housing or apartments, have parents who were unmarried or unemployed or both, and be Medicaid recipients.
