The purpose of the present study was to make clear the feature of social dependency demand in junior-high school students. One hundred and eight male and 93 female junior-high school students were asked to rate 16 items to the extent of how dependent they were on 4 objects (mother, father, one of the most intimate friends of the same sex, one of the most intimate friends of the opposite sex). In analysis I, factor analysis revealed Intra-Dependency demand Organizations (Intra-DDO), and analysis of variance revealed their main dependency demands for each object. In analysis II, factor analysis revealed Inter-Dependency demand Organizations (Inter-DDO). Both Intra-DDO and Inter-DDO were different according to subject's sex. While male subjects had primarily instrumental dependency demand, female subjects had primarily psychological dependency demand, in addition to instrumental dependency demand.
