The present study focused on the psychometric properties of the Portuguese version of Trust in Physician Scale (TPS) in a sample of Portuguese type 2 diabetics and their partners. Three hundred and forty diabetics diagnosed in the year prior to the assessment participated in the study as well as their partners. The validity study revealed two factors that explained 53.66% of the total variance: "Trust in Relationship" explains 40.28% of the variance and "Trust in Competence" explains 13.38% of the variance for the diabetics; and for their partners 53.56% of total variance, 41.43% and 12.12%, respectively. The scale shows good convergent validity being correlated with adherence to medication and a good descriminant validity in terms of age and gender validity gathering the necessary conditions for its use with Portuguese diabetic patients and their partners.
