A latent variable model of the Family-of-Origin Scale for adolescents

The Family-of-Origin Scale (FOS) is a recently developed 40-item instrument originally designed to assess adults' perceptions of the family in which they were raised. A modified version of the FOS has shown promise for assessing adolescents' perceptions of the extent to which their family fosters autonomy and intimacy. The current study involved administration of the FOS to a large sample of adolescents currently residing with their family of origin. Confirmatory factor analysis supports the scale's original 13 theoretical constructs and establishes factorial validity. Follow-up hierarchical tests indicate the current confirmatory model provides a significant refinement over other plausible models proposed by several different authors finding a similar unitary factor employing exploratory factor analyses.
