基本人际关系取向（英文：Fundamental Interpersonal Relations Orientation, FIRO），由美国心理学家威廉·舒兹（William Schutz）于1958年创建的一种人际关系理论。该理论主要解释小型组群的底层人际关系，其基于分析人们在组群交往中追求的主要三种人际关系需求：爱（affection/openness）、归属（inclusion）和控制（control）。舒兹展开了一系列名为FIRO-B的测量方式，包括六类、九项的问答。该理论可用于测量和控制组织成员如何感受爱、归属和控制，或如何能够在组织中获取其他成员的回馈。

Fundamental Interpersonal Relations Orientation (FIRO) is a theory of interpersonal relations, introduced by William Schutz in 1958. This theory mainly explains the interpersonal underworld of a small group. The theory is based on the belief that when people get together in a group, there are three main interpersonal needs they are looking to obtain – affection/openness, control and inclusion. Schutz developed a measuring instrument that contains six scales of nine-item questions that he called FIRO-B. This technique was created to measure or control how group members feel when it comes to inclusion, control, and affection/openness or to be able to get feedback from people in a group. Unlike many instruments used to examine human interaction behaviors, and needs, the FIRO-B is and was extremely valid internally and externally using inferential statistics. Also, while no one knows exactly the "B" was thought to mean either behaviors, or it was version B. It is greatly useful to utilize on future managers, and employees, and from their training, workshops, and/or awareness can improve the individual, and groups of the organization. Lastly, college students overall test quite high in Control, possibly because they go to college so that it is more likely that they will have less bosses, or be one, thus satisfying their need for control.
