FIRO-B stands for Fundamental Interpersonal Relationships Orientation - Behaviour. It is an assessment designed to see how an individual's personal needs impact on their behaviours towards other people. The measurement is in two different dimensions: expressed behaviour and behaviour desired from others. In essence, this assessment measures how we would usually behave with others and how we expect others to behave towards us. It's designed to help us see ourselves, based on our own interpersonal needs. It provides feedback in assessing our needs for inclusion, control and affection.
