The Satisfaction With Family Life scale (SWFL) was developed by Zabriskie and McCormick to assess individuals’ satisfaction with family relationships and family life. The aim of our study was twofold: (a) to verify the psychometric properties of the Polish version of the SWFL scale, and (b) to confirm if it maintains the single-factor structure of the original SWFL. A total of 474 subjects from the general population were involved in the study, of whom 205 were women and 269 men. Confirmatory factor analysis (CFA) showed a very good fit of the single-factor structure of the tool. The Polish version of the SWFL scale demonstrated good psychometric properties with excellent test-retest reliability. The obtained results support the utility of the Polish version of the SWFL scale as a valuable measure of global satisfaction with own family.
