This research had three basic goals: (a) to identify manipulation tactics used in close relationships; (b) to document empirically the degree of generality and specificity of tactical deployment across relationship types (mates, friends, parents); and (c) to identify links between five major personality dimensions and the usage of manipulation tactics. Twelve manipulation tactics were identified through separate factor analyses of two instruments based on different data sources: Charm, Reason, Coercion, Silent Treatment, Debasement, and Regression (replicating Buss et al., 1987), and Responsibility Invocation, Reciprocity, Monetary Reward, Pleasure Induction, Social Comparison, and Hardball (an amalgam of threats, lies, and violence). The Big Five personality factors were assessed through three separate data sources: self-report, spouse report, and two independent interviewers. Personality factors showed coherent links with tactics, including Surgency (Coercion, Responsibility, Invocation), Desurgency (Debasement), Agreeableness (Pleasure Induction), Disagreeableness (Coercion), Conscientiousness (Reason), Emotional Instability (Regression), and Intellect-Openness (Reason). Discussion focuses on the consequences of the five personality factors for social interaction in close relationships.
