The aim of the study is to determine factors in health communication, when minorities areserviced in a language different from their mother tongue. Health care service satisfaction whendoctor and patient speaking the common language or the mother tongue is an important area ofinvestigation. On the other hand, when either of them speaking different languages, namely, generallypatients in the minority position speaking a language different from the one doctor speaks, healthcommunication becomes cumbersome for both sides resulting in low level of health care servicesatisfaction leading to ultimately wide range of complaints from minority patients. How attributesplaying roles on health care service satisfaction in minority patients by modeling the relationship isconducted. Therefore, single attributes and interrelated ones are determined. The data is collectedusing a questionnaire form based on stratified sampling method, 387 participants are included in theanalysis. Questionnaires were distributed among minorities living in Vienna area. The factors that areimpact on health care service satisfaction are extracted by factor analysis. Questionnaire datacollected as verbal statements representing the subjective evaluations of participants transformed intomathematical functions using fuzzy set theory enables to model attributes affecting health care servicesatisfaction using fuzzy logic called fuzzy rule based systems. Modeling tool called Fuzzy Rule BasedSystems is a mathematical model in order to explain which single factors and/or interrelated oneshaving impact on health care service satisfaction are determined by employing fuzzy set theory andfuzzy logic, which are the components of the mentioned mathematical model. The findings suggest thatthe first expectation by minority patients from doctors is to respect to their cultural differences. If it ismet at the first glance, then health care service satisfaction tends to increase with the positive effectsof other attributes. If not, health care service satisfaction stays at lower with no other attributesplaying major roles. According to the findings of the study, other attributes or interrelated ones playsignificant roles on the health care service satisfaction when they are singly evaluated, which lead tocomprehend not only single attributes but also interrelated ones by minorities.
