Victims of stalking often experience a number of negative psychological problems including such things as fear, symptoms of depression, and anger. However, research on factors that lead to these outcomes is limited. The goal of this study was to first identify distinct subgroups of stalking victims based on measures of psychological problems resulting from being stalked. Once identified, the next step was to examine the influence of demographic and stalking-related variables on the probability of subgroup membership. The results revealed that respondents who were female, had a prior relationship with the stalker, experienced a greater variety of stalking behaviors, were divorced/separated, and reported receiving government assistance were more likely to be classified into subgroups characterized by a high probability of experiencing multiple negative outcomes.
