Objective: To evaluate the psychometric characteristics, convergent validity and reliability of the antiretroviral treatment satisfaction scale (ESTAR, escala de satisfacción con el tratamiento antirretroviral). Method: Patient satisfaction with ART was determined using the ESTAR questionnaire, developed in Spanish based on the English language version of the HIV-Treatment-Satisfaction Questionnaire (HIVTSQ). In order to evaluate this, internal consistency and test-retest reliability were measured. The construct analysis was performed by studying the covariance and correlation of the questions, and the convergent validity was assessed by using the MOS-HIV (Medical Outcomes Study HIV Health Survey) questionnaire as the standard, as was the content validity by the correlation between the ESTAR and the clinical and therapeutic variables. Results: The ESTAR is structured in two dimensions (clinical satisfaction and satisfaction with lifestyle) with slight modifications to the original version; question 4, discarded in the original version, has been reworded in the Spanish version, and question 9 was deleted because of low communality. As regards the testretest reliability, all the questions show significant intraclass correlation coefficients (p < 0.001). The internal consistency shows higher values than the original version in the lifestyle dimension (α = 0.81 vs.α =0.74) and in the total score (α = 0.84 vs.α = 0.82). With regard to convergent validity, the ESTAR presents significant correlations with the MOS-HIV as a whole and with different dimensions of it, especially the association with mental health, health distress and cognitive functioning dimensions. Conclusions: The ESTAR turns out to be a suitable, reliable instrument for evaluating satisfaction with ART by HIV+ patients.
