DELGADO, Artur Barata  and  LIMA, Maria Luísa. Contribution to concurrent validity of treatment adherence . Psic., Saúde & Doenças [online]. 2001, vol.2, n.2, pp.81-100. ISSN 1645-0086.

Non-adherence to medical regimens is likely the major cause of therapeutic failure. Besides that health professionals face difficulties on the assessment of rates of adherence. Based on Morisky, Green e Levine (1986)’s measure of medication adherence, a version with 7 items was developed. It was analysed, in diverse conditions of response, the internal consistency of the 7 items Measure Treatment Adherence (MTA) and its concurrent validity, through the pill count criterion. The MTA presented a good internal consistency in the condition of Likert scale response, and raised correlations in any condition of response. The response in form of Likert scale disclosed to greater sensitivity and specificity to detect the diverse behaviours of adherence.

Keywords : Adherence; Internal consistency and concurrent validity; Measure.
