Aim of the study:
The aim of the study was to develop and validate the Polish version of the Family Genogram Interview (FGI), an instrument designed to measure emotional processess conceptualized by Bowen family systems theory.

Subject or material and methods:
A total of 300 married women with at least one child aged 4 to 10 years completed a survey test battery comprised of NFFS, GHQ-28, DAS, DSI-R and PAS.

The results indicated that the NFFS has good psychometric properties. The four-factor structure of the NFFS, validated using first exploratory, then confirmatory factor analysis, was replicated. We confirmed its satisfactory internal consistency and construct validity as well.

NFFS consists of 30 items examining the emotional processes in the nuclear family. Statistical and theoretical analyses led to a four-factor model with the following scales: Symptoms in a Spouse, Marital Conflict, Focus on a Child and Emotional Cutoff.

Our findings confirm that the NFFS in a reliable and valid instrument which can be applied both in clinical practice and in research.
