A common definition of "conflict" is readily retrievable and applicable in the context of clinical evaluation – i.e., conflict has no particularly unusual primary meaning in clinical psychology. "Interpersonal" also operates as an ordinary adjective with the usual meaning. Thus interpersonal conflict is conflict between persons, as might be distinguished from intrapersonal conflict (e.g., cognitive dissonance). In some cases, one might also distinguish interpersonal conflict from impersonal conflicts with people in general, such as alienation, aggression, or other antisocial impulses when these do not have a specific person or a small group of specific persons as the object of negativity or source of opposition.
Two important inferences that one might consider based on such an evaluation include the plausibility of problems with social skills and problems arising from the other person(s) involved. People who have not developed strong social skills like empathy, conflict resolution, tolerance, or politeness experience interpersonal conflicts more often, but even people with strong social skills and other essentials of psychological health may find themselves at conflict with others who are the primary source of distress or disagreement.
