A Adler, often thought of as the father of birth order research, claimed that birth order can have lasting effects on one’s personality. He stated that birth order differences in personality are mostly due to siblings trying to compete for the attention of their parents by claiming certain niches or roles within the family (Adler, 1964). One theory underlying this need to establish a role is th...

In a comprehensive study (15,356 Dutch 9th grade students from 651 classes in 95 schools) we empirically tested the dimensional comparison theory (DCT) propositions formulated by Möller & Marsh (2013) as an extension of I/E theory, exploring methodological, theoretical, and substantive insights. According to DCT, academic self-concepts (ASC) are formed in relation to dimensional comparisons in ...

The rationale for this presentation is a theoretical model indicating that people who perceive themselves to be more effective, more confident, and more able accomplish more than people with less positive self-perceptions. Support for this prediction is strongest in academic self-concept research where a substantial body of research in support of the reciprocal effects model now exists. On this...

This study tested a multi-faceted, hierarchical self-concept model for university students. Self-concept was conceptualized as composed of three 1 order facets, each with three 2 order facets: academic self-concept (capability, achievement and confidence), social self-concept (same-sex peer, opposite-sex peer and family) and self-concept presentation of self (personal confidence, physical and h...

A review of the literature indicates that (a) very little attention has been devoted to measurement problems plaguing the study of self-esteem and (b) few studies employ more than one type of self-esteem instrument. This study addresses these issues by using eight measures of self-esteem involving self-reports, ratings by others, and a projective instrument. Their intercorrelations are examined...

Data of n = 401 students (60.4% female) from German academically oriented secondary schools were collected at the middle of grade 10, at the end of grade 10, and in the middle of grade 12. Parallel measures for mathematics and English were collected, representing school grades, academic interest, academic selfconcept, and coursework selection (advanced vs. basic course). Consistent with a prior...
