TI  - The Portuguese Version of the Immunosuppressant Therapy Adherence Scale (ITAS) 
      among Liver Transplant Recipient Patients: Translation and Psychometric 
      Properties.

AB  - INTRODUCTION AND AIM: Transplant recipients are chronically ill patients who rely 
      on medical treatment throughout life to achieve positive results. Despite that, 
      medication nonadherence after liver transplantation is extremely common. The 
      self-report, one of several methods for measuring adherence, is easy to apply and 
      low cost. Thus, this study aims to translate and validate the Immunosuppressant 
      Therapy Adherence Instrument (ITAS) in Brazilian Portuguese for liver transplant 
      recipients. MATERIAL AND METHODS: A total of 139 liver transplant recipients were 
      selected from a general hospital, who were assessed by using the Portuguese 
      version of ITAS. The scale was translated based on the model proposed by Wild, et 
      al. and its psychometric properties were assessed. RESULTS: The average 
      Cronbach's alpha coefficient was 0.830. ITAS and Basel Assessment of Adherence with 
      Immunosuppressive Medications Scale (BAASIS) presented significant correlation, 
      with a Spearman's rho coefficient = 0.300 (S = 309,580; p < 0.001). The area under 
      the receiver operating characteristics (ROC) curve was 0.638 (95% CI: 0.557 - 
      0.715). Factor analysis results indicated that the carelessness factor model was 
      the optimal model, and the factor "feeling worse" was the lowest. CONCLUSION: The 
      Portuguese version of ITAS has adequate psychometric properties to measure 
      adherence to immunosuppressant therapy.
