The growing concern for the development of teenagers has brought up issues regarding the role of the family system in shaping the personality traits of children. Alfred Adler (1870-1937), an Austrian psychiatrist who introduced the psychological/therapeutic model, "Individual Psychology," highlighted the importance of birth order positions in understanding the personality traits of children. Interestingly, Malaysian counselors, in particular, have been known to engage in using Adler's birth order theory. The purpose of this study was to determine whether or not a relationship exists between personality patterns of an adolescent and birth order position in Malaysian society. Generally, this research analyzes the suitability of using Alderman theory in Malaysian society. Respondents (N=161) were identified as male Form Five students in secondary school. The Sidek Personality Inventory was used to identify 15 basic personality traits. Data analysis was done using the Statistical Package for Social Science (SPSS). The research found certain dominant trait patterns although no significant relationship existed between birth order and personality trait. (Author/JDM)
