SANCHEZ-BERNARDOS, M. L; ALONSO RODRIGUEZ, E; HERNANDEZ-LLOREDA, M. J  y  BRAGADO, M. C. A preliminary study of the role of birth order and parental investment in adolescent interpersonal orientation. Clínica y Salud [online]. 2007, vol.18, n.1, pp.9-21. ISSN 2174-0550.

This paper addresses the role played by both birth order and perception of parental investment in adolescent interpersonal relationships and affectivity. A sample of 287 high-school students was administered the DOI-J, the PANAS, and a scale of parental investment. The results showed that firstborns did not differ significantly from laterborns on any of the interpersonal dimensions or affectivity. However, parental investment perception had significant effects in the sense that it favored that adolescents were more considerate with others, more able to experience positive affects, and less aggressive. The interaction effects emphasize the socializing role of the parental investment perception on laterborn interpersonal development. Results are discussed and new research trends are suggested.
