(Coleman, 1968(Coleman, , 1969a(Coleman, , 1969b it has been argued that projective techniques can be used to study child development, particularly those aspects of development which are connected with interpersonal relationships. In the 1969b study pictures were used as stimuli, the children being required to tell a story about each picture, and by analysing the themes expressed by each age group a number of important dimensions of development began to emerge. However, it was felt that further exploration of these dimensions was necessary, preferably with a different technique, in order that some light might be shed on the results from a different angle. For this reason the sentencecompletion method was chosen as an additional means of studying the development of interpersonal relationships.Much work has been done on the use of the sentence-completion method as a diagnostic instrument (for review see Goldberg, 1965), but so f a r little attention has been paid to it as a means of studying child development. Two exceptions to this have been the papers of Harriss and Tseng (1 957) and Lessing, Pribyl and Patek (1966), though both papers have limited their scope by concentrating on positive and negative attitudes to parents and peers, the latter paper making a comparison between normal and disturbed children. In the present study, it was decided to concentrate on the normal adolescent but to investigate a range of interpersonal situations, and for this purpose an entirely new sentencecompletion test was developed.I I .-METHOD.
Subjects.Subjects were 153 adolescent girls from a grammar school in a workingclass area of London. They were drawn from the first year (N=52), the third year (N=56) and the sixth year (N=45) of the school, the mean ages of the three groups being 1 1 : 10, 13 : 9 and 16 : 1 I. In the first and third years two of the three classes in the school were included, while all the girls in the sixth year tock part.
Procedure.In order that the results should be comparable to those of the previous study (Coleman, 196913) a sentence-completion test was developed to cover 27
