This study is a re-analysis of published data on psychological support for 609 junior high school students (317 boys, 292 girls, mean age = 14.1, SD = 0.8) based on the self-report, Psychological Support Scale, to evaluate sibling order as eldest or youngest and sex. In an earlier study, the questionnaire had been modified to be applicable to junior high school students. The study re-examined the data by extracting samples for categories of eldest and youngest siblings, for re-analysis of self-reported psychological support by sibling order and sex. Eldest children reported receiving more psychological support from both mother and father than youngest. Also, eldest boys received significantly greater psychological support from both the parents than the youngest boys or girls.
