Experience of caries has a clearly negative impact on the quality of life in preschool children. The instrument Early Childhood Oral Health Impact Scale (ECOHIS) measures the oral health-related quality of life in preschool children (Child Impact Section) and their families (Family Impact Section). The aims of the study were to develop a Swedish version of ECOHIS and to evaluate the instrument's reliability, validity, and internal consistency. Additionally, to analyse the oral health-related quality of life (OHRQoL) among preschool children who have experienced caries. The original ECOHIS questionnaire was translated into Swedish. Caregivers of preschool children aged 2-5 years were recruited at dental clinics in Sweden, to participate in the study and answer the Swedish version of the ECOHIS (S-ECOHIS). The internal consistency and reliability were assessed by using Cronbach's Alpha coefficient. In order to measure the consistency of the study, the questionnaire was re-tested two weeks later for 10 of the caregivers and assessed by using intra-class correlation coefficients (ICCs). The results from S-ECOHIS were described as descriptive data and independent t-test was performed. All data were calculated using SPSS (Statistical Package for the Social Sciences). S-ECOHIS was developed by translating the original English version using a double-blinded technique. A total of 274 caregivers participated in the study and completed the questionnaire. Cronbach's Alpha was 0.84 for S-ECOHIS, 0.83 for CIS, and 0.66 for FIS. The ICCwas 0.95 for the test-retest of S-ECOHIS. Among the respondents, 117 (43%) had children diagnosed with caries, while 157 (57%) had children without caries. The children with caries reported a higher total score of 5.97 (SD 6.16) of S-ECOHIS, compared to the score of the non-caries children 0.77 (SD 1.38) (p < 0.001). The Swedish version of ECOHIS that was developed demonstrates good validity, test-retest reliability, and internal consistency. The findings show that the oral health-related quality of life is adversely affected in preschool children with caries, with particular vulnerability observed among children with untreated caries. These results indicate that S-ECOHISis suitable for use in future clinical and research endeavors.
