The aim of this study was to assess the dimensionality of YFHS-Swe and identify possible unique factors in the evaluation of youth-friendliness. YFHS-Swe was answered by 1110 youths aged 16 to 25 years visiting youth clinics in Northern Sweden. Thirteen factors were identified by exploratory factor analysis and except for one factor they all proved to fit well and have good reliability when assessed by the confirmatory factor analysis. The YFHS-Swe proved to be credible and suitable for assessing youth-friendliness of differentiated health services in Sweden. With cultural and linguistic adaptations, it can be used in similar settings internationally.
