The Flint Infant Security Scale measures an infant's behavior in order to establish the child's ability to accept dependence upon their caretaker and to put forth effort when the occasion calls for it. Both these aspects of behavior are reflections of the child's sense of security and feeling of self-worth. The Scale, consisting of the Manual and the Scoring Booklet, reveals the extent of compatibility that exists between the mother or caretaker and the child, so that weaknesses may be identified and adjustments undertaken. When the "psychological parent" of the child is a caretaker other than the natural mother or father, the Scale proves of special value to physicians, social workers, and child care agencies responsible for adoption placements and foster care. The Manual discusses the theory behind the Scale and gives directions for administration, interpretation, and scoring. The method of development, validity and reliability, and distribution and range of scores are detailed also. The Scoring Booklet contains questions to show positive or negative behavior in situations common to young children and apparatus for determining the score of the observed child. (Author)
