The Family-of-Origin Scale (FOS) is a recently developed 40-item instr
ument originally designed to assess adults' perceptions of the family
in which they were raised. A modified version of the FOS has shown pro
mise for assessing adolescents' perceptions of the extent to which the
ir family fosters autonomy and intimacy. The current study involved ad
ministration of the FOS to a large sample of adolescents currently res
iding with their family of origin. Confirmatory factor analysis suppor
ts the scale's original 13 theoretical constructs and establishes fact
orial validity. Follow-up hierarchical tests indicate the current conf
irmatory model provides a significant refinement over other plausible
models proposed by several different authors finding a similar unitary
factor employing exploratory factor analyses.
