Victims were identified and contacted for an initial interview by trained police officers 48 to 72 hours following the report of the crime. A total of 160 out of the 259 victims contacted agreed to be interviewed, and 95 gave followup interviews 4 to 6 months later. Impact of criminal victimization was measured by several variables which were condensed into two scales: the debility scale based on effects on health, increased fearfulness, and suspicion and the isolation scale which involved increased self-protective behaviors, purchase of equipment to improve physical security, reduced mobility and independence in daily living activities, and social withdrawal. Financial losses from the crime were considered a separate area of impact. Measured social and demographic characteristics of the victims included age, sex, occupation, income, ethnicity, marital status, work status, and home ownership. The sample was further divided into 68 victims of personal contact crimes and 98 victims of property crimes. Analysis using the debility scale showed that higher socioeconomic status insulated victims from fearfulness and health problems, but that the isolation index was unrelated to victim and situational factors. Differences between moderate and high impact groups in the debility scale depended on the type of crime and the amount of loss rather than socioeconomic characteristics. Personal crimes and a stronger debilitating impact on middle class victims than property crimes. Lower class victims, however, were disturbed by both personal and property crimes. Because of the wide variance in impacts reported by victims, the study cautioned future researchers about the complexities involved in victimization surveys of the elderly.
