The purpose of the present study was to determine the effects that the handicapped have on their siblings from two perspectives. Study 1 was conducted on a group of subjects who had handicapped siblings (the "handicapped siblings" group, hereafter called the HS group) and a group of subjects who did not have handicapped siblings (the "non handicapped siblings" group, hereafter called the NHS group). We used a questionnaire to compare the attitudes of these subjects toward their siblings. The results showed that the two groups had different attitudes toward their siblings. In particular, the fact that the subjects of the HS group had marriage problems and apprehensions about the future showed that they had a lot of conflict and stress when they reached a crossroad in their life. In study 2, we investigated the emotional characteristics of the HS group using the P-F Study (Picture-Frustration Study), which focused on feelings of frustration. The results showed that males in the HS group showed a tendency toward Extraggression (E-A) and females in the HS group showed a tendency toward Intraggression (I-A) and Imaggression (M-A).
