Content analysis, a technique in which inferences are derived from the communication of interacting parties, is not utilized enough in mainstream negotiation research. The purpose of the present article is to outline the benefits and limitations inherent in the content analysis technique, to provide a comprehensive review of content analysis systems that have been used in the past, and to evaluate the existing systems in an effort to guide readers in the decision process. This article aids the potential consumer-any person considering the use of content analysis in negotiation research-in making informed choices regarding this technique. Choice among existing systems should be based upon one's research question and upon accepted standards of quality.A system that is relatively comprehensive, well grounded in theory, and demonstrates acceptable levels of reliability is advocated. Specific recommendations regarding quality systems are provided.Negotiation is pervasive in nearly all forms of human social interaction. Whenever the desires of two or more people are perceived to be mutually exclusive and the players involved choose to develop an agreement to satisfy their needs, a form of negotiation is at work. Negotiation can be applied to all levels ofsocial conflict, ranging from a quarrel between friends or family members to full-scale warfare between nations. As a result, social scientists have long been interested in the processes and outcomes associated with negotiation.Performance is a major issue for much of the negotiation literature. Optimal performance, in the form of an agreement that objectively maximizes the interests of all parties involved, is regarded as highly desirable. As such, most of the investigation to date has focused upon two forms of dependent measures: economic measures and social-psychological measures (Thompson, 1990). Economic measures focus solely upon outcomes of a negotiation. They do not take into consideration the process by which those outcomes are achieved, and a standard of optimal performance is often used as a comparison by which to judge the effectiveness of a negotiation. Socialpsychological measures focus on both the process and the outcome of negotiation. They are usually in the form of a set of ratings of the outcome, of one's opponent, and of oneself (Thompson & Hastie, 1990).
