Özet

The importance of trust within health care is widely acknowledged. Measuring patients' trust in health care systems may contribute to plans for the financing, delivery, and outcomes of health services. Although many scales are available to measure patient trust, less attention has been paid to the multidimensional nature of trust in health care systems. The purpose of this methodological study was to adapt the Multidimensional Trust in Health-Care Systems Scale into Turkish and to evaluate its psychometric properties for a Turkish patient population. The scale was adapted into Turkish through a translation and back-translation process. The content validity of the scale was assessed using expert approval. The psychometric properties of the scale were investigated by collecting data from 232 hospitalised patients in Ankara during theperiod of 1 January-30 December 2010. An exploratory factor analysis identified that the eigenvalues for the three factors of the scale were 7.30, 2.61, and 1.21; these three factors explained 65 % of the variance. A confirmatory factor analysis indicated a sufficient model fit for the construct validity of the scale. Cronbach's alpha for the total scale was 0.87, as well as 0.91, 0.82, and 0.61 for the three subscales; the Spearman-Brown split half reliability coefficient was 0.67. Despite the low internal consistency of the subscale 3, evidence from this study supports the validity and reliability of the Multidimensional Trust in Health-Care Systems Scale. This instrument can be used to measure multiple aspects of trust in the health care system; however, as trust is a contextual phenomenon, further work is needed to test the psychometric properties of this scale both in Turkish and different cultures.
