[DSQ-13-youth: measuring instrument for patient satisfaction with dental attendance among adolescents, young adults and parents of young children].

The Dental Satisfaction Questionnaire (DSQ) is a questionnaire consisting of 31 items assessing patient satisfaction with dental attendance. By means of factor analysis (principal component analysis), the number of items of the DSQ was reduced to 13, which together constitute the DSQ-13-youth. The first objective was to investigate the psychometric properties of the DSQ-13-youth; the second was to compare the satisfaction scores on the various dimensions between and within subgroups (23-year-olds, 17-year-olds and parents of 5-year-olds). The DSQ-13-youth has 4 domains measuring patient satisfaction with dental attendance. The internal consistency of those domains was high; the correlation between the domains low to moderate and the factor structure was highly congruent in the various subgroups. The differences in satisfaction scores between and within subgroups were small. The DSQ-13-youth is a reliable instrument to assess patient satisfaction with dental attendance among adolescents, young adults and the parents of young children in urban areas.
