In Adler's Theory of Individual Psychology the significance of birth order position in the family constellation depends on the interpretation given to it by the child, which in turn influences his character. This study surveyed the perceptions of middle children in large families. Subjects (N=13) were middle children in families of more than five children and an odd number of children, selected from referrals by researcher's relatives, friends, colleagues, and students. Subjects were mailed a questionnaire requesting demographic characteristics, level of education, occupational status, family interactions, and family members' perceptions with space for comments. Results showed that for the middle child respondents: (1) 85 percent perceived that they were most like one of their parents; (2) 85 percent had taken care of the youngest child; (3) 77 percent reported that one family member was picked on; (4) 38 percent reported having received the most time of their parents; and (5) 31 percent felt they got away with the most in their families. In general, results of the survey indicated that middle children from large families with odd numbers of children were content with their birth order position. Fourteen tables and the study instrument are appended. (ABL)
