Comparative StudyMethods for the analysis of binary outcome results in the presence of missing data.
An important, frequent, and unresolved problem in treatment research is deciding how to analyze outcome data when some of the data are missing. After a brief review of alternative procedures and the underlying models on which they are based, an approach is presented for dealing with the most common situation--comparing the outcome results in a 2-group, randomized design in the presence of missing data. ⋯ This method allows the researcher to define the range of all possible results that could have resulted had the missing data been observed. Extensions to more complex designs are discussed.

Physical aggression in early marriage: prerelationship and relationship effects.
Spousal physical aggression at 30 months after marriage was predicted for 393 young couples who were interviewed for a longitudinal study. The prerelationship predictor variables were history of violence in the family of origin, aggression against others during childhood and adolescence, and personality characteristics. ⋯ For both sexes, there were direct paths to marital violence that were not mediated by characteristics of the relationship, as well as paths that originated in or flowed through indicators of the marital relationship. Implications for intervention through marital therapy, individual therapy, or both are discussed.
