When the stimulus pictures showed ambiguous male-female relationships, the assaultive men generated higher need-for-power scores than the average of both control groups combined but did not differ from the maritally conflicted group on need for power. The assaultive men had lower spouse-specific assertiveness scores than either control group, however. A discriminant analysis based on need-for-power and assertiveness scores correctly classified the wife assaulters and maritally conflicted males 90 percent of the time. The resulting profile of assaultive men was of a group high in the need to exert power in relationships with women but lacking in the verbal resources to do so. It was hypothesized that this combination of a high need for power and a deficit in verbal ability to generate influence produces chronic frustration, which may increase the risk of violence when combined with other factors.
