This paper describes an alternative version of the Network of Relationships Inventory, which was designed to assess how frequently different relationships were used to fulfill the functions of three behavioral systems-attachment, caregiving, and affiliation. Psychometric and validational evidence is presented including: a) high internal consistency for all scales and composites, b) a second order factor structure of support and negative interactions for each relationship, c) moderately high stability over a one year period, d) moderate convergence among different reporters, e) theoretically meaningful differences among different relationships, f) moderate associations among different relationships, g) associations with the original Network of Relationships Inventory, and h) relations with observed interactions with mothers and friends.
