The assessment of relationship can take many forms. For starters, there are many types of relationships. A relationship between spouses is significantly different than a relationship between co-workers. But all relationships have to do with one individual interacting with others.
Our products that assess relationships include measurements of marital attitude (Marital Attitude Evaluation), how an individual uses relationships to influence the workplace (Profiles of Organizational Influence Strategies), and general interpersonal skills (Inventory of Interpersonal Problems).
